Pat has released a new version of DirectCompute Benchmark. This tool allows you to benchmark DirectX 11 latest general-purpose computing feature by calculating tons of FFT-like data and some memory transfers. DirectCompute is an application programming interface (API) that takes advantage of the massively parallel processing power of a modern graphics processing unit (GPU) to accelerate PC application performance.

Minimum Requirements
Windows Vista SP2 or Windows 7
DirectX 11
Latest DirectX End-User Runtimes
GPU with DirectX 10 support and above.

Recommended Drivers
ATI Catalyst 9.12
Nvidia ForceWare 195.81

Update: A new version (0.35) is now available.

Download this file in our downloads section.

Great tool!! At last the numbers make some sense?

Got now: GPU:M34027 CPU: M3157 (multithreaded)

GPU:S34036 CPU: S535 (singlethreaded)

Finally the GPU shows its true coloros agains the goold ol cpu.

Hi! The numbers you get represent relative computing performance. M15k for GPU is a 'typical' result for 9800gt (OC/AMP Edition, 700/1800/900 clocks, 112SPs, 16ROPs) so if you get M30k it means your card is twice as fast as 9800gt AMP+. The same for CPU, getting M5k means your CPU reach 1/3 of 9800gt performance doing the same job (same codepath, sse2 optimized multithreaded code).

"S" for CPU means singlethreaded code while "S" for GPU means passing D3D11_CREATE_DEVICE_SINGLETHREADED flag to the DirectX11 device (could be misunderstood as a singlethreaded code execution on GPU)

Unfortunetly ATI has not yet published DirectCompute enabled drivers for HD4xxx/DX10.1 GPUs...:/ You need HD5xxx or any GeForce8+.

Please try 0.25 version, if it's still not working for you, try latest NOT beta forceware (191.07 for now). If it still doesn't work, please write me PM and I will try to help/fix it.

Any chance you could explain why a GTX 260 is scoring over double that of a 5870? Something looks really wrong with this benchmark, does the code favour Nvidia cards somehow?

ok it seems it was with 0.15

it seems working fine now (well results are less strange)

i do M13000 with gtx 280 factory settings (which seems very low)
and M1100 with Q6600 @ 3Ghz
