AMD Bulldozer for chess

[Joerg Oster]

Hi,

for those interested, here are some numbers on my new 8-core machine.
Specs: AMD-FX8120@4GHz, 8 GB RAM, Asus M5A99X EVO, Ubuntu 12.04 LTS

Komodo3sse42 up to depth 19:

Code: Select all

info depth 19 time 28392 nodes 27770784 score cp 19 nps 978120 pv g1f3 d7d5 d2d4 g8f6 c1f4 c8f5 e2e3 e7e6 f1d3 f5d3 d1d3 b8c6 b1c3 a7a6 a2a3 f8d6 e1g1 e8g8 h2h3 h7h6 b2b4 d6f4

Stockfish 2.2.2, own compile:

Not too bad!

It would be nice to have a comparison with say an Octa Intel setup to see how things stack up. There must be a lot of positive things in having 8 cores on a single die, and at 4 Ghz the speed is very good.

Hi
How those that compare to an i7 3930k ?

The i7-3930K better perform much above it, as its price is almost 4x as the AMD CPU. ($600 vs $175)

Indeed, some numbers for comparison would be nice.

Here you can find some bulldozer benchmarks:

Maybe you missed that I'm running Linux on my box.
So no Fritz Benchmark. Thank you anyway.

Well, it is nice to have 8 cores on one die. Unfortunately, Bulldozer CPUs are running on the hotter side. So you definitely need a very good cooling.

But the speed at 4 GHz is better than I expected. I read several reviews about the Bulldozers and their poor performance, especially with 1 core.

Of course, an Intel 8 core system is faster. But you have to spend much more bucks, too.
