Intel Ironlake OpenGL Performance On Mesa 9.1

Last weekend there was a fair amount of chatter about Intel not planning to bring some OpenGL 3.0 functionality to Ironlake. The hardware supports some of GL3, but the Intel developers are more concerned about newer generations of Intel graphics hardware plus other driver features. How though is the Intel Ironlake (Clarkdale/Arrandale) performance with Mesa 9.1? Here's some benchmarks.

LLVMpipe Picks Up Support For New GL Extensions

While LLVMpipe is now commonly used as the default software fallback on the Linux desktop in cases where there is no OpenGL hardware driver available, it remains limited to OpenGL 2.1 compliance and doesn't see too much love by developers. Fortunately, VMware developers continue to take some care of this driver and today there's now support for two new OpenGL extensions pertaining to texture buffers.

OpenGL 3.0 Features For Intel Ironlake Unlikely

With the release of Mesa 9.1, Intel Sandy Bridge and Ivy Bridge graphics continue to be advanced while at the same time the Intel Linux developers are hard at work on future Haswell and Valley View graphics support. Having only limited resources to go around, Intel developers have quickly lost interest in earlier generations of hardware.
