Linux 3.18 Kernel: Not Much Change With Intel Haswell Performance

For those wondering whether there will be any exciting improvements with the Intel DRM graphics driver in the Linux 3.18 kernel, here's some OpenGL performance benchmarks.

At least when carrying out performance tests with Mesa Git master (now at Mesa 10.5.0-devel), there doesn't appear to be any significant performance improvements when testing with an Intel Core i7 4770K "Haswell" CPU bearing HD Graphics 4600. When comparing the stable Linux 3.16.0, 3.17.0, and 3.18.0 Git daily kernels for this system with standard HD Graphics 4600, there really isn't exciting about this latest Linux kernel.

There's roughly the same performance between Linux 3.16/3.17 and 3.18:

The performance changes appear to be minimal with the forthcoming Linux 3.18 kernel:
