Since last week's release of OS X 10.9 "Mavericks", I've begun benchmarking my few Apple systems to see how the performance compares over OS X 10.8. In this article are our first benchmarks of OS X Mavericks final as we look at how the performance changes for a Haswell-based 2013 MacBook Air.

With our investigation into the potentially large performance changes in the Linux 3.12 kernel due to a CPUfreq change that can vastly improve the 3.12 kernel Radeon graphics performance, I also checked for Core i7 Haswell performance changes with this latest kernel. However, if using a low-end Core i3 CPU is the performance any different for 3.12? Here's test results.

Most often when running Intel Linux graphics benchmarks these days we're using Haswell hardware since that's where the most exciting developments are now happening with it being the latest-generation Intel products. However, we routinely go back and test older generations of hardware. With it having been a while since last running Mesa benchmarks with Ivy Bridge, especially now this week Mesa 10.0 receiving OpenGL 3.3 support, it's time for some new benchmarks.

A few days back I delivered Linux OpenGL benchmarks of many different Intel graphics processors spanning the Sandy Bridge, Ivy Bridge, and Haswell generations. In this article are complementary Intel 2D benchmarks of the various generations of Intel processors using the now-default SNA acceleration architecture.

The Core i7 4960X Extreme Edition processor is Intel's new $1000+ CPU built atop their "Ivy Bridge" architecture and features six physical cores plus Hyper Threading. The i7-4960X is running at 3.6GHz with a 4.0GHz Turbo Frequency and is all around a super-fast processor. Under Linux, the performance is fantastic and it runs great on modern Linux distributions.
