Gallium3D LLVMpipe Driver Shows Progress
The last time there were thorough LLVMpipe performance benchmarks on Phoronix was last November when benchmarking Mesa 9.1-devel with LLVM 3.1/3.2. Since that point, Mesa 9.1 has become stable and there's been many Gallium3D/LLVMpipe driver changes in the past three months. LLVM itself also continues to advance and saw the release of LLVM 3.2 while LLVM 3.3 is now under heavy development.
For some quick benchmarks of the latest LLVMpipe code to end out February, benchmarks were done on the AMD FX-8350 Eight-Core "Vishera" system used for yesterday's Low-End NVIDIA/AMD GPU Comparison On Open-Source Drivers.
The same software/hardware setup was used and the lowest of these low-end graphics cards on the open-source Gallium3D stack were compared to LLVMpipe as of the same code revision. Aside from the OpenGL performance, with this latest LLVMpipe testing it seems the software driver running off the CPU is now working better for a larger selection of the OpenGL Linux games commonly used at Phoronix for benchmarking.
