OS X Mavericks Brings Not Many Performance Changes

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.

Core i3 Haswell Linux 3.12 Kernel Benchmarks

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.

Intel Ivy Bridge Benchmarks On Mesa 10.0 With GL 3.3

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.
