    They have been so burned by 20nm failing that they seem to have changed their strategy. They'll no longer be first - Vega will release only when 14nm and HBM2 are mature. I doubt Polaris 10 will be G5X either.
    That's twice in four nodes they've had to scramble.
    32nm TSMC ... gone.
    20nm TSMC / GF - somewhere between 'gone' and 'nope'.

    Yes, what was supposed to be Pirate Islands was cancelled, Polaris should be an advanced Pirate Islands, I'm curious if we will see what Fottemberg said about a tiled architecture.

    Ah, nothing particularly new then, just the old 1266/2304 results, and a couple more that have turned up.

    Again, AMD may be keeping final clocks highly under wraps, and ditto for a potential 2560 shader SKU.

    And failing these, it'll have better perf/$ ... and be available. We hope.

    That's only an old benchmark with a 720p resolution and Fiji doesn't scale very well with old applications, it needs graphics engines more focused on compute and asynchronous compute.

    In any case if the benchmark is true and Polaris continues close to Fury using higher resolutions it will be an extremely good card for 300$ or less, because the 980ti goes from 18% faster at 1080p to 6% faster at 4k compared to Fury according to computerbase. Custom cards would close that gap or the ycould be faster with Dx12.

    Eh... that isn't exactly how history went down.
    In 2014, I knew there wasn't going to be any AMD GPUs on 20SOC. What was stated by AMD was that they were working on a few 20nm products. At the time that most likely meant some of the smaller APUs. It later turned out they were talking about some of their ARM chips.

    When 2012 TSMC roadmaps dropped 20G and 20SOC moved to line up with 28HPM, that was a strong indication of an underlying issue with 20nm (which turned out to be leakage). Around the same time they were talking about bringing 16FinFet forward, another strong indication of something wrong with 20nm planar.





    So if TSMC knew in 2012 that 20SOC was a big enough bust to bring 16FinFet forward by 2-3years... I'm pretty sure most of their customers were aware of that as well, and even if they weren't directly told the simulations and early shuttles would have made it clear.

    Wonder what info is so juicy that they can't talk about it for another month. One paper seems to have "Po" written on it which could mean one day is dedicated to Polaris. They might talk about Zen and Vega, maybe... Can't see why they'd try to keep such a tight lid on Polaris when people are already prepared to buy it and the 1080/1070 have already been detailed and "released".
