Stream

[Brucifer]

For anyone that's interested, we've had a bit of a discussion going on the distributed.net threads of the FDC forums concerning benchmarks on some of the Nvida GeForce and AMD Stream GPU's.

I picked up a Radeon HD 4850 last night, and the benchmarks are;

[Aug 21 15:35:18 UTC] RC5-72: using core #0 (IL 4-pipe c).
[Aug 21 15:35:29 UTC] RC5-72: Benchmark for core #0 (IL 4-pipe c)
0.00:00:08.84 [489,096,269 keys/sec]
[Aug 21 15:35:29 UTC] RC5-72: using core #1 (IL 4-pipe c alt).
[Aug 21 15:35:42 UTC] RC5-72: Benchmark for core #1 (IL 4-pipe c alt)
0.00:00:10.59 [411,941,905 keys/sec]
[Aug 21 15:35:42 UTC] RC5-72 benchmark summary :
Default core : #0 (IL 4-pipe c)
Fastest core : #0 (IL 4-pipe c)

So it moves along at better than twice what I'm getting out of a cuda BFG GTX 260. Uses one PCIE 6-pin power cable, not two like the GTX 260. Feels like its putting out about the same (maybe less) heat than the 260. It crunches one single work unit each 8 seconds, so it's like rocking along like the cuda 260 was before the compiler problem hit. And it's not the fastest card of the stream line, but I'm pretty happy with the way it runs.

So there you go Nflight, your AMD world is now in the thick of it in the GPU world as far as crunching on RC5-72 anyway!!!

Bok made this statement which will rock the world of AMD. 8-18-09

They've just announced that they should have the ATI integration into the BOINC 6.10.x stream within a month, it's basically the major thing they are working on now that the gridrepublic/facebook 6.8.x version is out the door..

Woo Hoo

yup, these cards rock!!!
