Re: Fully unrolled RC5 on FPGA

Oops, a slight mistake in the information on x86.  Didn't carefully check to
make sure I was looking at the highest clocked chips sold.

There is actually a 2.8 Ghz dual core Opteron out, the Opteron 2220, which
would make 23.3 mkeys/sec.
And even though the Core 2 architecture is slightly less efficent at RC5
than the Opterons, the fastest dual core Core 2 chip is 3.2 Ghz which would
make 23.8 mkeys/sec, narrowly beating out the Opteron 2220.

For x86 the fastest dual core chip is the AMD Opteron 285 (dual core; 2.6
Ghz) at 22 mkeys/sec, while the fastest overall chip is the Intel Core 2
QX6700 (quad core processor; 2.66 Ghz) at 40 mkeys/sec.
For the PPC it is the PowerPC G5 (dual core 2.5 Ghz) 38 mkeys/sec

The Opteron and G5 can also be run in dual processor configurations for
Opteron 285: 44 mkeys/sec system
PowerPc G5: 76 mkeys/sec system

(All those numbers are based off of benchmarks run on the v2.2012 client run
on slower versions of the chip and adjusted for the fastest speed currently
sold).

Hello,

Where those numbers come from?

>From the "Client Speeds Database" on disctributed.net I can't find
performances exceeding 10 Mkeys/sec for x86 processors.
For power PC, the best I can find is around 20 Mkeys/sec.

Thanks.
