I recently picked up a Founders Edition RTX 2070 GPU for other purposes, but since it also runs PG, I thought it might be useful to see how well the new card does against its most logical competitors: The GTX 1070 that it replaces and the GTX 1080 that more closely matches its price point. So here goes...

I will be comparing results from the RTX 2070 FE at $599 US dollars with the EVGA GTX 1080 SC2 at $450 US dollars (which is out of stock at that price and selling for $699 on Amazon) and with the PNY GTX 1070 XLR8 at $480 US Dollars (but selling for $400 on Amazon). It is also worth noting that the GTX 1080 is a second generation model with 352 GB/s sec. memory bandwidth rather than the 320 GB/s speed of the first generation 1080s.

The RTX 2070 is running the new 416.34 driver. Numbers for the GTX 1080 are with the 384.76 driver. The GTX 1070 is running the 399.24 driver.

Both the RTX 2070 and GTX 1080 numbers will come from an installation in the same machine: a Dell Precision T5810 workstation with Xeon E-1650 6-core Haswell CPU and 32GB of DDR4 RAM running Windows 7 Enterprise. The GTX 1070 numbers are from an installation in a Dell Precision T1600 workstation with Xeon E3-1270 4-core Sandy Bridge CPU and 8GB of DDR3 RAM running Windows 10 Pro. All GPU test numbers come from these machines while running either Cullen or Woodall LLR multi-threaded to match the number of real cores (either 4 or 6), with Hyper-threading left on.

GPU loads are all measured via GPU-Z software.

First up...PPS sieve. This is a CUDA application and the oldest GPU app at PG. The GTX 1070 comes in at a respectable 445 seconds per work unit, or about 650k credit per day if running 24/7 crunching. The GTX 1080 soundly beats that mark with a 290 seconds per work unit value, or about 1 million credit per day. The RTX 2070 betters both, however, by a fairly significant margin at about 230 seconds per work unit, or about 1.25 million credit per day. If PPS sieve is your pleasure, then the RTX 2070 is a clear winner (unless you're okay picking up a a used 1080 at lower prices).

Next up...GFN15. This GFN level uses the slowest OCL2 application, and higher end cards often struggle to maintain anywhere near a full work load completing such short units without running more than one work unit at a time. These tests are running only a single instance. The GTX 1070 comes in at 55 seconds per unit, or about 41k credit per day. The GTX 1080 manages 45 seconds per unit, or about 50k credit per day. The RTX 2070 comes in at 48 seconds per unit, or about 47k credit per day. Here, the 1080 would seem to be a better choice and the cheaper 1070 a great option as well, but that comes with a caveat. The RTX 2070 is typically running at about 60% load here and the 1080 at about 75%, so doubling up GFN15 work will likely yield a stronger performance for both cards (and potentially show the 2070 to be better overall). Frankly though, if the GFN15 numbers are your game, then a mildly overclocked GTX 1060 6GB model might be your best option as it runs at higher load on single units coming very close to the GTX 1070 numbers.

So what about GFN16...also on the slower OCL2 app, but larger than GFN15 and requiring less frequent communication between the GPU and CPU. Well, loads on all three cards are still not full, but they are notably higher than for GFN15 reaching upper 70s in percent load regularly. The GTX 1070 comes in at about 180 seconds per unit, or about 48k credit per day. The GTX 1080 is faster at about 150 seconds per unit, or about 57k credit per day. Both are smoked by the RTX 2070 here at 90 seconds per unit, or almost 96k credit per day. So why is this so different from the GFN15 result? The difference most likely reflects the more consistent load across all the cards, whereas on GFN15, the 2070 was considerably under less load than either Pascal card.

Next up...GFN17 mega. Again, the slower OCL2 app, but larger numbers now mean a consistently higher load breaking into the 90%+ range on all three cards. The GTX 1070 clocks in at 546 seconds per unit, or about 69k credit per day. The GTX 1080 is only modestly better at 499 seconds per unit, or about 75k credit per day. Much as with GFN16, the RTX 2070 crushes both Pascal cards coming in at 255 seconds per unit, or about 148k credit per day.

Next, we'll skip up to GFN19. Here we are running on either OCL5 or the slightly slower OCL3 depending on the card. The Pascal cards tend to be exclusively choosing the OCL5 option whereas the RTX 2070 tends to bounce between both (about two-thirds OCL5 and one-third OCL3), so I have averaged these for the 2070 results. Here we see some clear separation between the cards. The GTX 1070 is clearly the slowest at about 4800 seconds per unit, or about 134k credit per day. The GTX 1080 chimes in at about 3850 seconds per unit, or about 166k credit per day. The RTX 2070 is once again considerably faster at about 1920 seconds per unit, or about 334k credit per day.

So what about GFN20? These are quite large units, and on later generation NVidia cards should be expected to run exclusively the very fast OCL4 app version. That is true of both Pascal cards, but the RTX 2070 actually runs a mix of OCL4 and OCL5 across work units (with the OCL5 units being about 100 seconds slower than the OCL4 ones). Once again, I average these for the RTX 2070 numbers. The GTX 1070 gives very respectable numbers at about 13,500 seconds per unit, or about 203k credit per day. The GTX 1080 is of course faster at about 11,700 seconds per unit, or about 237k credit per day. Here again, the RTX 2070 is substantially faster at about 7,450 seconds per unit, or about 371k credit per day.

GFN21 units are quite large, and these typically run a mix of applications (OCL for AMD GPUs and older--i.e., Fermi--Nvidia GPUs and OCL4 for Kepler NVidia cards and newer, although some Titan, Quadro, and Tesla cards might choose OCL). The RTX card adds an oddity to the mix as these units are exclusively using OCL5 on this card. The results for the GTX 1070 come in at about 50,550 seconds per unit or about 252k credit per day. The 1080 predictably is better at about 43,350 seconds per unit or about 294k credit per day. The RTX 2070 is considerably faster than both Pascal cards at about 28,250 seconds per unit or about 451k credit per day. Indeed, that is faster than the typical GTX 1080 Ti (about 31-33k seconds per unit). Given that the RTX card chooses the usually slower OCL5 app makes this result particularly impressive, and may suggest some room for improvements for the Turing cards over all on larger GFN work.

The AP27 app (which uses OCL code) offers its own pattern. The GTX 1070 is able to do each work unit in about 1725 seconds resulting in about 202k credit per day. The 1080 outclasses its little brother by quite a bit doing each unit in about 1100 seconds for about 319k credit per day. The RTX 2070 is better still, but only by a modest amount at 963 seconds per unit for about 363k credit per day. Of note, these crunch at 99% GPU load even on the 2070, and it also has noticeable, but tolerable screen lag.

And one last test, manual sieving on for GFN21. Here I'll post results for the RTX 2070 only (if I have time later, I'll add the 1070 and 1080 comparisons). Running the manual sieve with the default B=7 option, I get a rate of about 172 p/day with zero screen lag. Pushing the option to B=10, the rate jumps to about 507 p/day with minimal screen lag. Maximizing the option to B=13, the rate climbs to about 580 p/day, but the screen lag is noticeable now though manageable (and very similar to running AP27).

So what can we conclude? Unlike many of the online gaming style review that show the RTX 2070 to be a 10% to 20% improvement in those venues, the new Turing card produces a very nice boost compared to its Pascal cousins. In all apps except GFN15 (where it is fairly even with the GTX 1080), the RTX 2070 is noticeably faster. Indeed, for anything but the smallest GFN work, the 2070 gives more bang for the buck, sometimes by a large margin.

Some things to keep in mind as you are digesting my evaluation. First, my 2070 is an FE, which means that it has a mild overclock already. Entry level 2070s at stock clocks can be gotten for $499 US dollars, but these will not produce the same numbers that you have seen here (although I expect that they will still be faster than the Pascal cards). Second, two other Pascal competitors should be considered: the GTX 1070 Ti and GTX 1080 Ti. I don't have access to either of these cards, but the 1070 Ti (being a bit cheaper than the 1080 with similar performance) might be a cost effective option compared to the 2070. The 1080 Ti, however, is more expensive than the 2070, and I suspect that in many cases, the 2070 will match or better that card. Third, if you don't mind the risk of picking up a used card, the cost-per-credit/speed equation might tip more in the favor of the Pascal cards as I have seen GTX 1070s going for between $200 - $225 US and GTX 1080s going for between $300 - $350 US. Fourth, if you have unlimited funds, buy a Volta card. There are some Tesla V100 cards that are on PG, and for example, there numbers on GFN20 are about one-half the seconds/twice the credit per day as the 2070 (but you really need unlimited funds as those cards go for several thousand US dollars).

I hope this is helpful, and would welcome some comparisons showing similar numbers for the GTX 1070 Ti, GTX 1080 Ti, and both the other Turing cards (2080 and 2080 Ti).

Thanks for the detailed look at the 2070!

I will provide some numbers for a 1070 TI later tonight or tomorrow. It is paired with a Coffee Lake i5-8400 running WOO on 5 of 6 cores and Windows 10 Pro.

To start: AP units take about 1350-1375 seconds.

I did run the GFN benchmark when I first bought the card, but instead of posting that I will run some real units and see what happens with those.

genefer benchmark results above.

AP27 around 1000 seconds
GFN16 around 75 seconds
PPS sieve around 160 seconds

Seems like I'm getting faster times in GFN16 and PPS Sieve. My card is the Gigabyte Windforce model. Driver as reported above. In case it makes a difference I was using a 6700k system for test with Windows 7.

http://www.primegrid.com/results.php?hostid=917270
AP units are still there at time of writing and a single GFN16 unit. Looks like sieve has already been purged.

Edit: also...

First up...PPS sieve. This is a CUDA application and the oldest GPU app at PG. The GTX 1070 comes in at a respectable 445 seconds per work unit, or about 650k credit per day if running 24/7 crunching. The GTX 1080 soundly beats that mark with a 290 seconds per work unit value, or about 1 million credit per day. The RTX 2070 betters both, however, by a fairly significant margin at about 230 seconds per work unit, or about 1.25 million credit per day. If PPS sieve is your pleasure, then the RTX 2070 is a clear winner (unless you're okay picking up a a used 1080 at lower prices).

Running two PPS Sieve units at a time, my MSI Gaming X GTX 1080 needs 462 seconds to complete them (ie 231 seconds/unit) and which translates to 1.26 million credits per day, thus matching the results for your 2070. I have the card on factory OC with no intervention from me while using driver 397.64.

Perhaps others with a 1080 can chime in with their PPS Sieve results.

1070 Ti: 522 seconds (two tasks), 345 seconds (one task)

AP:

GFN17M:
1080 Ti: 358
1070 Ti: 439

That's on Ubuntu with an Athlon 760K x4 crunching two WCG tasks, DDR3 RAM. A Gigabyte GTX 1080 Ti Turbo 11G and a Zotac GTX 1070 Ti Mini, to be precise.


Any chance of getting some data for manual sieving (GFN21) on the 2070?

Scott - thank you for the write up on 2070. Last night I ordered an FE 2070 open box for 430$.

I would add that RTX 2080 Turing has memory bottleneck on GFN similar Pascal 1080 vs. 1070.

Just as 970/980 or 1070/1080 - the RTX 2070 has better core/bandwidth ratio than a 2080. As we know Genefer thrives with fast memory bandwidth.
GV100 (Volta Titan) OCL transform with HBM2 is nearly 2x faster than the 2080 OCL4/5.


Some impressions of my RTX 2080

-- RTX 2080 overclocks to the moon with minimal difference in power compared to 1080.

-- RTX 2080 has double the GTX 1080 performance for same power point.

-- RTX 2080 3x faster than a GTX 1060 or GTX 980/970 on PPS Sieve and Genefer.

PPS Sieve runtimes increased per WU compared to 39* drivers runtimes. Power usage is up and down on Pascal and Turing while Maxwell steady.
Is an PPS Sieve app upgrade in order? 4** drivers have PPS Sieve GPU usage and power all over the place.

-- GT 630 @ 1.2GHz (20W); 1900 seconds/WU
-- GTX 970 @ 1.5GHz (165Wavg / 175W Max): 494 seconds/WU
-- GTX 1060 3GB @ 2.1GHz (106W / 125W): 493 s/WU
-- GTX 1070 @ 2.1GHz (135W / 150W ): 333 s/WU
-- GTX 1080 @ 2050GHz (165W / 225W): 267 s/WU
-- RTX 2080 @ 2085MHz (167W / 225W): 153sec/WU

My 1080 completed a PPS Sieve WU in 225s/WU while 1070 was 315s/WU with 3** drivers. Even the 4** branch GTX 1060 3GB and GTX 970 are affected with runtimes 20-25s slower. Overclocked Turing lacks PPS Sieve scaling Kelper / Maxwell have. I believe Pascal and Turing is not being utilized completely. Gpu usage is all over the place instead of being pinned at 98% Maxwell / Kelper. Maybe an CUDA update will help out the newer cards find full potential.
GPU usage on RTX 2080 and GTX 1080 (1070) is currently only 67% with no CPU WU. With 1 CPU WU instance the GPU usage tanks even more.

My RTX 2080 boosted out the box at 2.0GHz. Running n=20 with these clocks had WU completion at 6920 seconds - choosing mostly the OCL5 transform.

n=19 runtime are 1800 seconds. Over 2X faster than GTX 1080.

I have a really busy schedule coaching soccer and working outside the office the next 4-5 days, but I'll see if I can do something along those lines later next week (been a long time since I manually sieved).

The AP27 app (which uses OCL code) offers its own pattern. The GTX 1070 is able to do each work unit in about 1725 seconds resulting in about 202k credit per day. The 1080 outclasses its little brother by quite a bit doing each unit in about 1100 seconds for about 319k credit per day. The RTX 2070 is better still, but only by a modest amount at 963 seconds per unit for about 363k credit per day. Of note, these crunch at 99% GPU load even on the 2070, and it also has noticeable, bu tolerable screen lag.

I can vouch for your AP27 results since I was getting a mean run time of 1080 seconds and which translates to 323,440 credits per day.

I may as well provide the rest of my figures:

GFN 15 -> 46 seconds/unit --> 47,916 credits/day
GFN 16 -> 171 seconds/unit -> 49,273 credits/day
GFN 17L -> 423 seconds/unit -> 86,155 credits/day
GFN 22 -> 44.3 hours/unit -> 364,497 credits/day

PPS Sieve -> 7.7 minutes/units* --> 1,260,842 credits/day (* 2 units running simultaneously)

Here's the testing I promised earlier!

System:
i5-8400 at stock
16GB DDR4-3000 2x8GB
GTX 1070 TI with factory overclock
Windows 10 Pro

Testing notes:
All times approximated after live task(s) run.
All tests were done one task at a time.
WOO was running on 5 of 6 cores.
All values are time in seconds.

Results:
AP27: 1360
PPS-SV: 415
GFN15: 61
GFN16: 190
GFN17L: 510
GFN17M: 542
GFN18: 1710
GFN19: 4230
GFN20: 12740

Post test thoughts:
So I'm pretty happy with the results of the 1070 TI given what it cost. haha. However, it seems to be a little slower than other 1070 TI's and even slower than Scott's 1070 in some tests. This may or may not be related to my testing methodology.
The screen lag I had on the larger GFN and AP units with the 1050 TI seems to be gone with the 1070 TI.
Currently the 1070 TI sells for about $550CAD and the 2070 is around $750CAD. So both offer similar bang/buck based on shared results here. So my old motto of "buy the best you can afford" is probably still the best thing to do.
My particular card does make a high pitch squeal when loaded to 100%. So GFN19 and larger give the squeal as everything else is less than 100% load.

Thanks again, Scott, for the insight into the 2070! There's not usually such in-depth posting about cards below the top end.

Cheers!

Thanks Scott for your post, very interesting!

ocl4 uses Shoup's modular multiplication (see Faster arithmetic for number-theoretic transforms, David Harvey, J.Symb.Comp. 60 (2014) 113-119) and ocl5 is based on Barrett's product/reduction.

The number of operations is smaller with Shoup's method but the value W' must be precomputed. Because of this, ocl4 lookup table (similar to the cos/sin table of the FFT) is twice the size of ocl5 table.
If GPU memory bandwidth is the bottleneck, ocl5 may run faster.
But what is surprising is that the RTX 2070 is the GPU which has the higher memory bandwidth per core.

To expand upon my results above I should also add which transform each test used for the GFN tests.
Also, since Scott added GFN21 I have also added GFN21 from my 1070 TI.

GFN15: OCL2
GFN16: OCL2
GFN17L: OCL2
GFN17M: OCL2
GFN18: OCL2
GFN19: OCL5
GFN20: OCL4
GFN21: OCL4 - 44700 seconds

So the 1070 TI nearly matches the 1080 in GFN21 and cost about $100CAD less at the time of purchase.

Any chance of getting some data for manual sieving (GFN21) on the 2070?


I have a really busy schedule coaching soccer and working outside the office the next 4-5 days, but I'll see if I can do something along those lines later next week (been a long time since I manually sieved).

Thanks. Wow, it seems increasing B values makes much more of a difference than I've seen on my Pascal cards. B13 is more than twice as fast as my 1080 Ti (270 P/day; though I've observed that manual sieving on Ubuntu is a bit slower than on Windows).

My 1070 Ti manages 180 P/day (B13 as well) on the same system as the 1080 Ti.

Thanks. Wow, it seems increasing B values makes much more of a difference than I've seen on my Pascal cards. B13 is more than twice as fast as my 1080 Ti (270 P/day; though I've observed that manual sieving on Ubuntu is a bit slower than on Windows).

My 1070 Ti manages 180 P/day (B13 as well) on the same system as the 1080 Ti.

How many instances are you running at a time? I settled on 2 with B11 (B9 if I'm browsing the web) on a 1080. I think there was minimal increase (maybe a decrease?) at B12 and stopped testing there.

maybe the reservation limit should be reconsidered

The reservation limit has been increased on an as-needed basis for those individuals who ask.

Only one, none of my cards* has ever needed more than one instance of the OCL executable to max out the core load. I didn't see any improvements whenever I tested it with two. B13 is usually the best choice, but there are exceptions.

*Speaking of exceptions, despite what I just said my new RTX 2070 FE runs best with two instances of manual sieving at the same time (590 P/day). With only one it's slower by about 15 P, but more importantly the load is fluctuating between 70 and 100% regularly (and P/day is going up and down correspondingly). With two, it's at 100% all the time. As Scott posted, B13 is best and screen lag isn't an issue for me, since I have the screen connected to another card (a 1060 3GB, Msieving at B9 when I'm using the computer and B13 when I'm not).

Update: I just increased my RAM speed from 2133 to 2666 (I got bluescreens when trying 3200 MHz first, apparently max. recommended memory speed for first gen Ryzens is 2666? Haven't dug too much into it, just glad my PC is working again). This greatly reduced the fluctuations with a single instance (P/day varying between 585 and 593, mostly the former), however two instances still seem a bit more consistent and efficient.

CPUs have an official ram speed support, so buying and using ram faster than that is a kind of overclock. The ram might be up to it, but there are there variables in the mobo and CPU that mean the ram may not run at its rated speed in any given system. This gets worse the faster the ram.

On Turing the same power behavior as at Pascal under CUDA applications? (pstate P2 instead P0 with reduced memory clock)

Yeah um, I have to admit I didn't actually realize this. I assumed if the RAM was compatible it would just run at the given speed (3200 in my case) and case closed. I only noticed this by chance when checking memory via the task manager. The BIOS had the speed set to auto, which apparently amounts to 2133. The more you know.

err, didn't take the CPU-only part at the beginning into account, it's more like 108,000 seconds (30 hours) based on pure GPU work. Based on this, that's 5% faster than a 1080 Ti.

This is some news. As I was considering getting 3600 or 4000 RAM for the new i7-9700k build... it may not run that fast? I know I can auto adjust the speeds, but, my impression was faster memory just sort of worked if you configured the speed settings right....

For primegrid and other crunching I for sure thought that faster memory would make a huge difference.

RAM may not often work at the advertised speed. So if you buy say 3600 expect to to max out stable at 3333 say. But at least you bought faster RAM in the first place.

It is hard to say anything with 100% certainty when running higher ram speeds than officially supported by the CPU. I've ran into my share of problems even at below 3000, but with modern Intel systems and modern ram kits, this seems to be less of a problem now. In my opinion, a modern 3600 kit is probably ok, but 4000 is starting to push it, both in speed and on the wallet. You can try to match a kit from the mobo manufacturer's QVL, but there are so many kits this is usually difficult. Otherwise, buy a kit that was released about same time as the platform you will be using it with. For example, I've heard sub timings were set a little differently for Coffee Lake than earlier. Doesn't mean you have to match them, but it just increases the chances of it working.

Faster ram will help with bigger FFT size projects, but not smaller ones.

OK, thank you for this valuable input. How about CAS latency? Worth it going for faster and not just worrying about MHz?

Within the limits of my testing for LLR-like use cases, it only has a very minor factor. Maybe leave it as a nice to have after you have optimised the rest. You may find, for high speed kits, manufacturers might be using similar chips to get the high speed. So timings are kinda similar in that area too.

Sounds good.

Do you think the memory speeds would affect the performance of an rtx 2070 or 2080? The main system RAM... I would think it will improve things all around in general.

I thought I saw somewhere that some systems can't "feed" enough info to the new 2070's and 2080's fast enough to use them at max efficiency. I would think RAM would be a somewhat limiting factor so faster would be better.

GPUs have similar problems to CPUs, but within their local ram. That is, video ram can limit the GPU cores from reaching their maximum potential. I'm not aware of system ram limiting GPU operation, unless you're so starved overall it is impacting wider system performance. Also some apps may be affected by the PCIe bandwidth. I don't know how PrimeGrid projects are impacted by this, if at all. Folding@home is apparently somewhat affected, coin mining isn't.

Thanks to all for this very informative and helpful post. This has made me to buy an overclockable 2070 card over 1070 Ti. It should be up and running towards end of this month. This will be my first upgrade in 5 years for a desktop GPU ;-)

Interesting thread. Anybody tried a 2060 yet? I don't see any on the Fastest GPUs page yet.

Thankyou for your very detailed post.

I very recently bought a pc and within a week, the graphics card died - so I get to replace it. I am strongly considering the 2070 or 2080 as I'll get a hunk of cash back which makes the original purchase less crazy. The place that is replacing the card doesn't have 10xx cards.
The original card was a generic 2080Ti FE which could do AP27 in 525 seconds and PPS sieve in 94 seconds. GFN20 in approx 90 minutes and GFN21 in just over 6 hours.

However the stats on PG's fastest GPUs is a little confusing as it contradicts what you have measured on the 2070 and my results on the 2080Ti.

PG's fastest GPU stats for AP27, (and considering just the 2070, 2080 & 2080Ti) suggest that the 2080 is the best choice, the 2070 the next best and the 2080Ti is less than half the speed of the 2080. I understand that the stats don't include what else the computers are doing or other details. And these stats change a bit.

I think I should pay more attention to your stats and what I know of the 2080Ti performance and guess that in fact for AP27, the 2080Ti is actually the fastest, with 2080 next and then 2070.

The 2070 is probably better value compared to the 2080.
And at this stage I am only considering Asus Rog Strix. Once I have decided on 2070, or 2080 I'll look at cheaper versions and consider the value of going with one of those.

If it comes down to it maybe I'll just flip a coin?

Someone could please comment to add to the fun? I've got a couple of days (or longer if need be) to decide.

It's computer parts...meaning get the best you can afford because tomorrow a newer, faster and better one comes out. Don't 'settle' for a 2070 if you can get a 2080 and don't settle' for 2080 if you can get a 2080Ti. Doing things faster is never a bad thing, PG just came out with the "Lucky" wu's and they are projected to take 24 hours to a couple of days on the 2080Ti. On a 1080Ti it's projected to take about 4 days.

Cheers Mikey. Thanks for your comments. You are correct, if I can afford the 2080Ti, it should be at least back on the table - which may/will ultimately lead to me choosing it. At least I have the weekend to convince myself that I reasoned carefully.

You answered you own question correctly.

If the collected statistics gathered from the results in the database seem wrong, they probably are wrong. There's many reasons why there will be confusing information in those statistics.

Have there been a change in how credits is calculated since this thread was active ?

I'm more or less a newbie running Boinc for 9 months now. I've added a lot of GPU's lately but the results are not what I expected. I have five 1660ti, one 2080ti and one Gt740 - this is installed in five computers. My total Boinc credit per day is around 1million to 1.1 million is that normal so I'm expecting to much ? Looking at the numbers in the evaluation in this thread I'm way off.

I'm running Primegrid mainly but a little GPUgrid, Einstein, Seti and Milkyway as well. I've tried running 2 WUs in parallell and it gives just a little better results.

Credit formulas haven't changed at PrimeGrid for several years. I can't speak to what other projects are doing.

Get a program like Gpu-Z or MSIAfterburner and check the load on your gpu, you may find that it's not using the full potential of your gpu and you can run multiple tasks at one time instead of just one at a time. That will also not only change from sub-project to sub-project here at PG but also from Boinc Project to Boinc Project as not all apps use the full gpu's capabilities. For instance I have a 1660Ti running Amicable Numbers and at one task at a time it only uses 3% of the gpu's processing power.

It also helps to match the gpu to the Project, some Projects run much better on an AMD gpu than an Nvidia gpu, you can look at the stats at each Project or just run one brand then the other brand and figure it out for yourself.
