Intel Broadwell users will love Ubuntu 15.04
The upcoming Ubuntu 15.04 Vivid Vervet is going to be an important release for users of new Intel Broadwell systems. It is expected to ensure that the hardware performs at its best and realises its true potential. The Ubuntu 15.04 release is still a couple of months away, but it already consists of a newer version of the Linux kernel and other new packages that have been shipped with Ubuntu 14.10, out-of-the-box. Ubuntu 15.04 is still on Mesa 10.3, but by the time of its release it will be on Mesa 10.4, if Mesa 10.5 is not possible.
The new Intel Broadwell systems have several updated Linux configuration benchmarks, which makes Intel Linux graphics more mature for the Broadwell hardware. When a comparison test was done between Ubuntu 14.10 stable and the current build of Ubuntu 15.04 to figure out the performance differences, it was proved that beyond the graphics, the latest Linux kernel is quite crucial for the best hardware support too.
The latest kernel also integrates CPU performance improvements, as optimisations have been made to the P-State scaling driver. There will be no GCC 5 in Ubuntu 15.04, which means the next version of Ubuntu will ship with GCC 4.9 as its code compiler. If the latest GCC code is upgraded into the system, there is always a possibility that the processors will perform much better.
