Earlier this week on Phoronix were new benchmarks of Ubuntu
Linux vs. Mac OS X using a new Apple Mac Book Pro with an Intel Core i5
CPU and a NVIDIA GeForce GT 330M graphics processor. When looking at the
tests results overall it ended up being a competitive race between these
two Microsoft Windows competitors. In some areas, like the OpenCL
computational performance, Apple's operating system commanded a sizable
lead. In other areas, like the OpenGL graphics performance, Ubuntu Linux
backed by NVIDIA's official but proprietary driver was in control.
Here's an additional set of tests showing the measurable leads of NVIDIA
Linux over Mac OS X with Apple's NVIDIA driver.
