    Maybe, but an independent command stream was one of the requirements for the flexible scalar. That would entail increasing the instruction buffer, by one "per wave", instead of using the first lane for wave level operations. It's possible the ALUs are 4x(16+1)+1. That could give each ALU/executing wave a scalar to prefetch and run wave level ops in addition to a dedicated scalar for the CU. Might also explain part of the transistor disparity and why we aren't seeing more CUs. It seems odd they made all those slides and didn't mention how many processors were in there. Quantities on ACEs, HWS, TMUs, ROPS, etc. Everything but the actual processor count, which is the big number everyone likes to show.

    Since the number of texture units do not change, it seems to be unchanged. Since GCN 1.0, it is capable of loading sixteen consecutive 32-bit (or four 128-bit) values from the L1 cache per clock, with the texture & data conversion unit sitting on the return data path.

    If we look at this https://www.techpowerup.com/reviews/MSI/GTX_980_Ti_Lightning/21.html, basically 480 furmark number is close to 270X and 760. With better (new) power management, I think on typical gaming situation 480 can be a bit lower than 270X. I can't find 1080 number since Nvidia throttle their card to never exceed their TDP(?), thus on game and on furmark, 1080 numbers are the same http://www.tomshardware.com/reviews/nvidia-geforce-gtx-1080-pascal,4572-10.html

    I guess performance magically jumped from vanilla 290 to 390X in the past month. How else do you explain 1.83 CF scaling and 6% ahead of 1080 a month ago.

    It's not GPU revision, it's used by AMD to differentiate SKUs which use same PCI device ID

    All it took is one post to trigger you, grow a thicker skin. And while you're at it merge all the Nvidia threads as well, maybe merge ALL threads into one megathread to keep it interesting :lol: This forum is really going downhill.

    too slow. Doesn't overclock.

    But hey, its cheap- ish. There's better value on second hand market.

    This single thread for all AMD is silly. All architectures all cards in the same thread? Impossible to find any info for the things you are specifically interested in.
    Please split these threads back out into some sort of usable manner. Per architecture at least.
    I also like the old "speculation thread, production thread" scheme.

    Have a vote to determine final thread setup ... until then mimic the GTX 1080/1070 thread setup. I'd agree having multiple thread fractures/spinoffs does tend to dilute and sometimes shorten the lifespan of threads.

    Take 20% off the power usage, and its still very high lol.

    Why only take 20%? 270X on typical gaming load is 119W according to techpowerup while on furmark it is 173W. 285 on typical gaming load is 184w, but on furmark it is 250w. 980ti exhibited a greater than 20% difference between typical gaming load vs furmark. Basically what I mean is just wait for the review.

    Good price on the FE, here its sold at 859 to 899 CHF ( apply a nearly 1:1 ratio with $ )
