Fritz Chess Benchmark (Windows 32-bit)

WinRAR and Fritz Chess are probably less important to most people than the other benchmarks we ran. However, the reason why we include them in this article is that their profile is so different from the other applications. In this way, we get more insight into the different new architectures.

Fritz Chess
Profile Total
Average IPC (on AMD 2350) 0.99
Instruction mix
Floating Point 4%
SSE 0%
Branches 17%
Performance indicators on Opteron 2350
Branch misprediction 12%
L1 datacache ratio 0.65
L1 Instruction ratio 0.37
L1 datacache miss 1%
L1 Instruction cache miss 1%
L2 cache miss 0%

We have said this before but it warrants repeating: you'll find a decent amount of complex branches in a chess program. 17% branches is not that extraordinary, but the fact that 12% of those branches are mispredicted is. If we compare a 2GHz Opteron 22xx with an Opteron 23xx, we should see if the improvements in branch prediction pay off.

The Opteron 2350 is about 3% faster than the Opteron 22xx, core for core, clock for clock. We believe we can assume that the branch prediction improvements are minor, as the Fritz chess benchmark runs in the L1 and L2 cache.

HPC

Several of the HPC benchmarks are too expensive for us to test, but we can get some information from AMD's and Intel's own benchmarking. According to Intel, the new Intel Xeon 5472 (1.89 score) is about 26% faster than the Xeon 5365 (1.5 score) when running the fluent benchmark. According to AMD, the Opteron 2350 is about 10% to 60% faster than a 2.33GHz Xeon E5345. That doesn't give us much comparison data, but at first sight it seems that AMD will be competitive in Fluent even at lower clock speeds (2.5GHz versus 3GHz).

We get a little more data in LS-DYNA. Both AMD and Intel have published results.



Intel's own marketing material seems to admit that a Xeon E5472 with 800MHz memory is just as a fast as AMD's quad-core at 2GHz. AMD's 2.5GHz model will surely take the lead in LS-DYNA. Looking at the Fluent and LS-DYNA benchmarks it appears that AMD will remain very competitive in the HPC market.

One benchmark where Intel's newest chip really shines is the Black-Scholes algorithm: as most of the calculations involve divisions, the new Xeon 54xx chips are about 50% faster than their older Xeon 53xx siblings, clock for clock. Unfortunately, our compilation of Black-Scholes failed on the quad-core AMD, so we have to postpone those results for now.

    Then why are you here? Details is what technology is about!

    I for one have a pet peeve with tech sites that use the wrong formats in their stories. Slightly damages credibility. Not to say this is a big deal in this case, though .gif is pretty much dead, unless you use an old browser on old tech, but then why would you be reading this story?

    Look on the bright side, at least this isnt a Codec vs. Codec story, where the author uses jpgs for such color-limited screenshots.

    I think the color depth was decreased alot more than 8 bit. That image only has 33 unique colors in it. Something went wrong with the dithering maybe? 256 is usually more than enough. Reply

    Who cares? The only part that suffers is the gradient at the top, all the relevant information is there, and this file is about half the size of what a PNG would be. Reply
