While more thorough and extensive tests are ongoing (e.g. our four-way file-system comparison on the Linux 3.10 kernel), up this Saturday morning are some new Linux 3.8/3.9/3.10 benchmarks from a Lenovo ThinkPad W510 laptop with an Intel Core i7 720QM CPU with NVIDIA Quadro FX 880M graphics controlled by the Nouveau driver.
These brief benchmarks, where the only variable at play was swapping out the version of the mainline Linux kernel as obtained from the Ubuntu Mainline Kernel PPA, were posted to OpenBenchmarking.org in 1305168-UT-LINUX310K27.
There's some performance changes as it affects the open-source Nouveau graphics driver, though it depends on the hardware/software configuration. For more see our earlier Nouveau 3.10 benchmarks.
While there's been various core work to the Linux kernel, as it affects the computational benchmarks, the Intel Core i7 performance in this notebook wasn't affected much in this latest round of benchmarks.
