    Phoronix: Intel Iris Pro 5200 Graphics

    While we have delivered tons of Intel Haswell coverage on Phoronix -- more than 100 stories on the latest-generation Intel processors and graphics written by your's truly -- one of the areas not yet covered have been the high-end Iris Pro Graphics with integrated eDRAM. We haven't been able to run any Linux benchmarks of the Iris Pro due to lack of hardware, but System76 is said to be soon sending over a review sample of their Galago UltraPro with Iris Pro Graphics 5200. In the meantime, however, a Phoronix reader has graciously lent us remote access to his Iris Pro system for Ubuntu Linux graphics testing.

    HD5200 seems very compelling. If they fixed their ogl stack i would give them my two thumbs up, now they only get one.

    It looks like one of the fastest Linux CPUs with open drivers. Will see if the "R" desktop CPUs are ever available somewhere, but no rush though, it still apparently needs 3+ months to be reasonably optimized.

    Can the eDRAM be used as an L4 cache for the CPU or is exclusively used for the GPU?

    Michael, could you include a comparator in the graphs, such as HD4400, please?

    As far as I've heard, it's a general-purpose cache. Would be interesting to hear more about how it affects performance (e.g. by comparing to a similar CPU without eDRAM).

    Looking forward to the review and benchmarks! Might I also suggest doing power draw tests with different kernels as well as battery life tests, given that this is meant to be an "ultrabook".

    Thanks!

    That's exactly it for me... Run a haswell with just a text console as a server and see how much that eDRAM helps vs the same CPU without when running various workloads. PostgreSQL anyone?
