Gallium3D LLVMpipe Still Needs A Very Fast CPU
Phoronix: Gallium3D LLVMpipe Still Needs A Very Fast CPU
The Gallium3D LLVMpipe driver is capable of running some old OpenGL games on the CPU at low resolutions assuming your processor is powerful enough...
i can t see any interess to use cpu as gpu in games
I agree completely. The point in LLVMpipe is so the compositor will still work, therefore it's the compositor/window manager that should be benchmarked.

well if an operation fail it do fallback to software rendering which translate into softpipe or llvmpipe[you choose the backend] and as far as i remember AMD use it as fallback for hardware that lacks vertex shaders like the IGP 4200 series[is in an post from couple of years ago, use forum search]

GPU-s use many cores too.
well llvmpipe can improve but never enough to replace an GPU unless in the future CPU suffer a very nasty redesign. that said the function of LLVM is to be the last resort and keep the compositor running not play games for that you have an GPU(that failed tho).
an additional benefits come from specific scenarios where you need a very simple compositor and an specialized GUI and you don't wanna waste power on an GPU[industrial systems, embedded, micro servers, gadgets,etc] and for this is magnitudes faster than the previous softpipe
