Intel Core i7 5775C: Once Going, This Broadwell CPU Is Great On Linux

With the Core i7 5775C + MSI Z97-G45 GAMING setup running well on Fedora 22, already I've published some benchmarks in recent days. In particular, I've been infatuated by the Iris Pro 6200 graphics under Linux: the Iris Pro 6200 graphics are really a dream come true for open-source Linux fans. That article shows the i7-5775C with the open-source Intel Linux driver compared to Radeon and GeForce discrete graphics cards on their respective open-source Gallium3D drivers... The Iris Pro 6200 graphics can really compete with mid-range AMD/NVIDIA GPUs when all are running on the open-source drivers.

The performance is great and Intel continues to be leading the charge of advancing Mesa 3D, DRM, and the rest of the open-source Linux graphics stack. As shared in an article this weekend, the i7-5775C is a big upgrade over the i7-4790K and AMD's A10-7870K Godavari for Linux graphics performance.

The graphics performance of the Core i7 5775C is really outstanding when considering it's backed by an open-source driver that Intel supports very well. The power efficiency also makes the i7-5775C even more compelling over Haswell's i7-4770K or i7-4790K. Before getting to the rest of the results, here is a quick graphics power efficiency comparison I did earlier this month between the i7 4790K and i7 5775C. The results are looking at the performance-per-Watt:

Higher power use with the i7-5775C, but much better performance and efficiency.

You can look more at the power efficiency numbers via this OpenBenchmarking.org result file.

The i7-5775C was going through more power than the i7-4790K, but the performance is worth it.
