DirectCompute Benchmark for Vista SP2 with DX11 or Win7

[DDStriker]

In case you run into any compatibility issues, I assume. And it's quite obvious as to why the benchmark won't run on Windows XP. It doesn't support DX10, let alone DX11.

Yes thats why i was curious about why dx9 was provided ^_^

Core i7 920

GTX 275

GPU checksum: 1370969.153194

CPU checksum: 1370969.611431

*** PASSED ***

DirectCompute Score: D14171

OpenCL not supported...(will get back to that :p)

CPU Score: M2499

Tested with new version this time, specs are slightly overclocked 4870 and a 2.6 ghz phenom II 810

[Yusuf M. Veteran]

People should be using the newer 0.45b version.

ViperAFK: Looks like you beat me, slightly. My results are here. :p

[tsupersonic]

Don't know where it's getting the 1477MHz from for OpenCL shaders clk, but that's wrong. The shader clock on the graphics card is 1350 MHz...

[ViperAFK]

The difference between ati and nvidia in this benchmark is pretty surprising seeing as how nvidia has been the one pushing this kinda stuff.

My 4870 got like twice the score as the GTX 260 above.

[Faks]

well here are mine result's !

[Subject Delta]

I get the impression that this benchmark is poorly written at best, not only are cards that are meant to be slower than mine (9800 GT, 9500) achieving far higher results, we also have a faster card (GTX 260) achieving significantly lower results than my card achieved. Something about this benchmarking app doesn't seem right to me :/

From what I've seen that confusion is becuase some people are still posting results from the .35 version which gives much higher scores.

[Subject Delta]

tsupersonic has the GTX260 he is using 0.45 and his result is a lot lower than mine, but your point is well taken about the 2 folks with the 9500 and 9800

[Eric Veteran]

9800 GT 1024, Intel E7300 C2D, W7x64U, 4GB RAM

And yes, it runs my $13.59 Crysis quite well. :D

[Yusuf M. Veteran]

I can't explain the discrepancy between the scores for NVIDIA but from what I've read, ATI's video cards have less CPU usage which results in a better score. Don't take my word for it though, I could be 100% wrong.

[Subject Delta]

Can someone please update the first post to link to build 0.45d, these results are so variable it makes direct comparison almost impossible

I've tried the 0.45b version, the thing refuses to benchmark my GPU, but has no problem with my CPU, however that score jumps all over the place.

Indeed, the scoring is interesting. Just for comparative measures for the folks who are still posting with v0.35, I got D10670, C59900, M2900, as I mentioned in post #11.

I got > 14000 on a single 9800 GT. :)

Done. :)

You probably used v0.35. That one gave me a score greater than 150,000. Use v0.45b for more accurate results.

I think even my 0.35 scores where substantially higher than yours, even though you own a faster card :/

Edit: Thanks Anaron, now can everyone who used 0.35 please re-do it, so that I can decide whether the program is dodgy or if it just doesn't like tsupersonic's system for some reason :laugh:

His program does not support the latest ATI drivers properly.

According to his ReadMe:

2) You DON'T need DX11 hardware, DirectCompute is supported on DX10 class devices if only drivers support it (forceware >= 190.62, Catalyst currently doesn't support DirectCompute on DX10/10.1 GPUs)

Now according to the latest ATI drivers (9.12):

This release of ATI Catalyst™ provides full support for DirectCompute 10.1 for the ATI

Radeon™ HD 4800 Series, ATI Radeon™ HD 4700 Series for both single card and ATI

CrossFireX™ supported configurations.

The older version (0.35) seemed to work fine as I used it in the past, but now its almost as if he intentionally blocked using the GPU to do the DirectCompute calculations on ATI cards.

That being said, I cannot get the program to give me a DirectComputer Score, I can get a CPU score, and thats the only score that updates no matter what test API I use. I do not have the ATI OpenCL drivers installed so I do not have a score for that either. But even without OpenCL I should still be able to get a DirectCompute Score, I did so on the past versions with the same exact setup.

[ViperAFK]

The results are very consistent on my machine when I re-run the tests. It is definitely odd that there is such big discrepancies in some systems that have the same video cards. The most likely cause I can think of is people running different driver versions.

err.... this is something on your end bro. I have cat 9.12 and a 4870. .45 works perfectly for DirectCompute, OpenCL and cpu.

[Subject Delta]

Same here, I can get a DirectCompute score with my 4850, and I also get an OpenCL score with the 9.12 hotfix.

I doubt it, at least not exclusively.

DirectCompute Benchmark 0.35: Generates a DirectCompute Score without a problem.

DirectCompute Benchmark 0.45b: Refuses to generate a DirectCompute Score.

How exactly is that "On my end"?

It may well be :unsure: but if a benchmark program can't keep scores properly, then it doesn't do its job right. Hopefully the future versions keep the scores consistent.

The fact that most other people with ATI 4 series cards are able to generate scores suggests a problem with your setup, not the application.

Absolutely, suppose a number of things could be causing it to work like that, but regardless of where the fault lies, I believe we can safely say that your score probably isn't overly accurate xD

While that is true, an older version of the application works fine, while the newer version does not. This means he changed something in his application that caused it to refuse to generate a DirectCompute Score for my setup. It does not mean my setup is faulty, it means his application is not working 100%. Also, Cy-Kill has the same issue as I do, so its not something wrong with my setup and my setup only.
