    Default 20-Way Intel/AMD/NVIDIA GPU Comparison With Ubuntu 14.04 LTS

    Phoronix: 20-Way Intel/AMD/NVIDIA GPU Comparison With Ubuntu 14.04 LTS

    Last week we covered a 13-way Radeon GPU comparison on Ubuntu 14.04 and we also looked at the state of Nouveau on Ubuntu 14.04 with many NVIDIA GeForce graphics cards. In concluding our latest round of open-source graphics driver tests from the upcoming Ubuntu 14.04 LTS "Trusty Tahr", here's a 20-way graphics processor comparison using AMD Radeon, NVIDIA GeForce, and Intel HD Graphics hardware.

    I chose the Radeon HD 6870 based on past reviews by Phoronix. Still seems like a perfect choice.

    Odd that new generation cards still don't run fast enough under the open-source driver to even equal it yet. Using non-free drivers would not be acceptable to me.

    Using catalyst the 6870 is still faster in some benchs... or too close to the performance of the new generation cards.

    Once again a misleading title on Phoronix. This is not a GPU comparison (it should be no question that a GTX680 is faster than a HD6870), this is a driver performance comparison.

    GCN hardware is newer architecture and use different driver, maybe that hardware architecture is just slower for these tests .

    But when we look closely only Radeon 6870 performs strange yes strange , it perfoms very good but why (so) better then Radeon 6950 And if we exclude that particular card Radeon 6870, results are very scalable and GCN hardware performs better .

    Oh, if it shows the same behavior with fglrx , then that prove 6870 is nothing but just some kind of exception rather than the rule .

    Unhappy as a 7790/260X/Bonaire owner...

    I'm in a glass case of emotion. https://www.youtube.com/watch?v=NJwveNAc1lo

    Lots of low numbers for me.

    One issue might be that the apps which would show off the GCN capabilities are also the apps where register allocation issues are preventing them from running on GCN hardware.

    Compare what Intel Haswell 4600 doing now and two moths ago in Prey especialy

    http://www.phoronix.com/scan.php?pag..._opengpu&num=4

    And now it is just double faster then Radeon 6450, but that is of course in line with expected performance difference if we look for example passmark results it is

    http://www.videocardbenchmark.net/gp...=Intel+HD+4600
    http://www.videocardbenchmark.net/gp...Radeon+HD+6450

    So that is now corrected, and now compare Radeon 6870, 6950 and 7850:

    http://www.videocardbenchmark.net/gp...Radeon+HD+6870
    http://www.videocardbenchmark.net/gp...Radeon+HD+6950
    http://www.videocardbenchmark.net/gp...Radeon+HD+7850

    I dont have these cards , but i am happy to assume that 6870 just does not have correct rendering .
