Compute Performance
ComputeMark (DX11 Compute)
ComputeMark is first 100% DirectX 11 Compute Shader benchmark and ultimate GPU burner. From ComputeMark.com.
Computemark doesn’t support a second GPU so we find the result is within margin of error of a single card. The result is a little higher because the Gigabyte GTX 980 is GPU1 and as mentioned on the first page it has a slightly higher boost clock than the reference version.
Luxmark (OpenCL Compute)
LuxMark is a OpenCL benchmark tool. The idea for the program was conceived in 2009 by Jean-Francois ‘Jromang’ Romang. The idea was quite simple, wrap SLG inside an easy to use graphical user interface and use it as a benchmark for OpenCL. From LuxRender.net.
Luxmark scales with multiple GPUs and we saw perfect scaling: a great result for OpenCL fanatics.
