With the upcoming Intel 3.0 X.Org driver the highly-tuned SNA acceleration architecture is replacing UXA as the default 2D means of Intel hardware acceleration. For complementing the recent Linux benchmarks of the Haswell Core i3 4130 with HD Graphics 4400, here are 2D benchmarks testing the Core i3 2120 with HD Graphics 2000 (Sandy Bridge), Core i5 3470 with HD Graphics 2500 (Ivy Bridge), Core i5 2500K with HD Graphics 3000 (Sandy Bridge), Core i7 3770K with HD Graphics 4000 (Ivy Bridge), Core i3 4130 with HD Graphics 4400 (Haswell), and Core i7 4770K with HD Graphics 4600 (Haswell).
The SNA testing was done on the same configurations as the earlier testing with Ubuntu 13.10 and the Linux 3.11 kernel and Mesa 9.2.0. More details and the 2D/3D Intel Linux GPU benchmark results can be found via 1310097-SO-HDGRAPHIC26.
The results are basically as expected -- with Haswell generally doing the best for the GTK+ and Qt tests -- given the processors and the current state of the SNA back-ends.
