Matr1x is a custom kernel developed by XDA recognized developer mathkid95 who is also the dev behind the Matr1x custom kernel for the Google Nexus S. This time, the said dev is ready to mod another Nexus device with this new custom kernel.
The recent build is still being updated by the developer and many have commented on the amazing battery optimization that comes with the package. Its recent version comes with ARM CPU Topology which makes your device more efficient. The GPU has also been overclocked to 450 MHz and all cores have been undervolted to 100 mV.
