Linux 3.19, 3.20/4.0 Doesn't Do Much For Intel HD 5500 Performance

Yesterday I ran some benchmarks from the new Core i3 Broadwell NUC to see how the latest Mesa Git affects the OpenGL performance for the Core i3 5010U chip with HD Graphics 5500. Today I'm complementing that testing to see if the latest Linux kernel Git makes any difference for this low-end, low-power Broadwell chip.

Intel Iris Graphics Performance On Linux 3.19 Shows Some Regressions

For any Intel Haswell Linux users with Iris Graphics thinking of switching to the Linux 3.19 kernel when it's released in what might just be a few hours, be forewarned as testing this weekend revealed there looks to be an OpenGL performance regression attributed to this new kernel.

A Five Year Old NVIDIA GPU Can Still Beat Broadwell HD Graphics 5500

I'm still benchmarking many laptops around here with the current build of Ubuntu 15.04 as part of my large forthcoming laptop comparison pitted against the new Lenovo ThinkPad X1 Carbon with Intel Broadwell processor. For another perspective on the Broadwell HD Graphics 5500 OpenGL performance, here's a laptop comparison against an old ThinkPad with discrete NVIDIA graphics.

Broadwell Linux Ultrabook Running MUCH Cooler Than Haswell

Aside from the performance benefits of Broadwell, particularly in having greater graphics capabilities, laptops and ultrabook designs are much more power efficient than former Haswell products. Here's some quick tests I did today comparing the Broadwell-based Core i7 ThinkPad X1 Carbon to my former Haswell-based Core i7 ASUS Zenbook ultrabook.
