GPU Compute
'DirectCompute and OpenCL Benchmark' demonstrates the significance of what is already known, that Radeon is simply the choice when one needs GPU computing power especially in OpenCL, delivering up to 2x performance in OpenCL for this benchmark.
With Luxmark, having only selected the GPU under test and not the CPU, we see almost 3x between NVIDIA and AMD in OpenCL.
For Folding at Home, we were not able to run the CUDA test so we only compare using OpenCL and not CUDA optimisations.
Coin Mining
For AMD we used standard GUIMiner with OpenCL
GPU | Algorithm | Overclock | GPU clock | GPU temperature | Fan speed | Hashing Speed | Total Power |
---|---|---|---|---|---|---|---|
R9 270X | SHA | Out of the box | 1150 MHz | 80c | 44% | 400 to 420 mhash/s | 250 Watts |
GTX 760 | Scrypt | Out of the box | 1111 MHz | - | - | 179 to 205 khash/s | 242 Watts |
For reference, the HD 4600 Integrated GPU in Intel's current flagship consumer CPU, the i7-4770K only acheives 5.9 mhash/s in Guiminer/OpenCL.
For NVIDIA, Since CUDA generation GeForce GPUs are poor at standard mining algorithms, we tried the 'new' Cudaminer for Scrypt based mining by Christian Buchner and got better results from this software
C:\guiminer-scrypt-64-004\cudaminer>cudaminer --benchmark -C 2
