In preparing for the AP27 Oktoberfest Challenge some of you may be wondering "How many more points can I get by running my CPU also?" I did some testing and here are the results.

Core i7 7700k Kaby Lake 4 core
completes 4 workunits in about 47000 seconds
equivalent to 1 workunit done every 11750 seconds

Core i7 3770k Ivy Bridge 4 core
completes 4 workunits in about 62000 seconds
equivalent to 1 workunit done every 15500 seconds

Ok, now let's compare these CPUs to a 5+ year old Maxwell generation Nvidia GTX 750ti. Not exactly a high end GPU, but very power efficient when released.
It completes a workunit in 6800 seconds.
So, as you see the lowly 750ti is more than twice as fast as the Ivy Bridge CPU and still much faster than even the Kaby Lake!

Newer GPUs such as RTX 2080 Ti can be over 20 times faster than the Kaby Lake and the fastest current GPU, a Tesla V100 is over 45 times faster!

When I threw my 1950X at the AP challenge last year, it took a bit over 18 hours for one task. That's with HT on (pretty sure I established that it does help a bit for AP), so if you have all 32 threads loaded, it amounted to one task every 35 minutes, or close to a GTX 980 in throughput. Not too shabby.

We can HT AP?

We can HT AP?

I am wondering why after nearly 26 hours of running on 4 cpu's the Octoberfest why the elapsed time indicates only 50% of the total hours ran? Maybe the cpu's are not running at more than 50% effort?
