I collected some speeds on various platforms (using ppsieve-0.3.3 on CPU and 0.1.3f on GPU), all values in M p/s

749; Intel C2Q Q9550 (4 Threads)
533; Intel Xeon E5405 (4 Threads)
1334; Intel Xeon E5420 x2 (8 Threads)
1140; Intel Xeon L5408 x2 (8 Threads)
602; Intel Xeon E5504 ES (8 Threads)
870; Intel Xeon W3520 (8 Threads)
2193; Intel Xeon L5640 x2 (24 Threads)
895; Nvidia GeForce GTX 260 216
2005; Nvidia GeForce GTX 460

Interesting that the GTX 460 is only 10% slower than the newest L5640 in dual-config. This server was around 2700 Euro exklusive VAT and used 270 Watt during the test according to the built-in power-monitor (60 Watt per CPU).

For the CPUs, is the speed the cumulative speed across all threads, or the speed for a single thread? I'm assuming those are cumulative speeds.

This is done on the console, the sieve started with as much threads as the computer is able to handle. So it is cumulative for a computer with the stated CPU-count.
