    Well I think you can call the "VR for 200 bucks" a feature. :lol:

    AMD is also focusing on one card per eye it seems. So 2 480s at $400 or 8 gigs at $450 / 460 would be a very nice vr feature if games took advantage.

    Features? The only thing these VR pinch-pennies care about is saving a few bucks.

    With 8xMSAA?.the test was with that level of anti aliasing.

    None. Let's hope we get something more exciting when NDA lifts.
    Yes.

    Meh then.It seems both Nvidia and AMD only got the improvements inherent to the new smaller finfet process.The thing is AMD needed a real architecture improvement.
    As someone has said this 200 dollars card is the logical improvement in perf/dollar we have had always with new nodes, nothing extraordinary.
    The thing is we have been stuck so much with the 28nm node that a 980 has become like a mytical expensive card (and Maxwell was in fact the biggest only architectural attributable jump in perf/wat ever, along with R300 and G80) that seemed imposible to be bought at decent prices.So being able now to buy a RX 480 with perf of a 970 seems incredible.

    If that is what you believe then you are not looking closely enough.

    Hint: Look at the clocks.

    Arent the clocks attributable to finfet nodes?.

    Two things:
    First, what we don't know yet is the actual power consumption of the RX 480. One 6-pin connector only means >75 watts. It still could be VERY low.
    Second, AotS is a showcase benchmark for AMD, yes. And here, we will probably see the least performance increase (uplift? ;)), because honestly, we expect to see improvements to the weak points of the architecture and AotS mostly shows off the strong ones. So, perf slightly above Hawaii XT could be the lower end of what to expect.

    AMD said 150W.

    some of the clocks but very little, Hexus article on this they asked the lead engineer on Pascal, about the clocks, they had to do extensive changes to the architecture to get those clocks.

    Techpowerup stated TBP 150, not sure if they are going by the slide or not though could be just some confusion.

    Just "Power: 150W". That isn't very specific. Is it powertune limit? Or TDP, or total board power, or typical gaming power, or just PCIe specification (75 W via PCIe + 75 W via 6pin)? AMD used a very vague formulation - maybe they have a reason. We'll see in less than four weeks.

    Hope AMD is deceiving, until than I assume 150W power draw.

    When was the last time you saw a graphics card draw exactly the amount of power provided by pcie-slot + power connectors? (excluding one dual gpu abomination which goes comfortably over what it shoudl draw)

    The card can physically draw 150W from the power sources. That means that in the worst case scenario it has to consume less by a safe margin than that.

    Well within 3d
    Usually there's some breathing room. If it really does push things to the point that board power is right up to the expansion slot spec, that would be worrisome.
    The Powertune target historically is lower, and generally has to be. The power delivery to the GPU is not perfect and other consumers of power take some out of the overall board power. The PCIe spec is not absolute about crossing the limit, but having a measurable chunk of consumption stuck above the power limit would stretch things to meaninglessness.

    GDDR5 7750 variant. Rated 75W, PCIe only, same for R250. R265/270 (150W with 1 6pin). GTX 640 (GK107 GDDR5) was PCIe at 75W.
