    I wonder what happens at a normal 4xAA and higher res. It might even be behind HD7970. At least in
    a few games. Might even be further ahead who knows.

    No word necessary: it's impossible to engineer such thing to have the mass production version skirt the edge of what's possible. You •have• to add a guard band to avoid excessive returns. It's probably different with the x990 and x90 cards because those are low volume affairs anyway, but you cannot afford to be inundated with returns.

    17.18 x 18.55 comes out to 318 mm^2. So is that with the heat spreader on? The slide on that site still says it being 294 mm^2.

    Manufacturer die-sizes are always a bit below, that the ones you can measure on a package.

    I'd say you covered the bases there.

    That slide shows the 580 as having the exact same load temp as a 7970. All of the reviews I've seen put the 7970 anywhere from 4°C to 10°C cooler under load. Seems fishy.

    That measurement includes the encapsulator, the chip itself will be smaller.

    Txaa, 128 tmus, 256 sfus, adaptive vsync etc there is also a dieshot

    I wonder why they left the LDS/L1 combo size inchanged?

    With only 0.5 million transistors more than GTX 580 they get 40-50% more performance. So, how?. Have they ditched DP logic?.

    No mention of cache sizes?

    Now I wonder why AMD's boards are longer when Nvidia has faster memory and yet has shorter boards.

    Because Nvidia has better cooling solution?.

    Wasnt it due to requiring longer traces on the board?

    SMX reminds me old TPC but CCs were seperated 3 parts there.. Fermi is 1, Kepler 2 and Maxwell will be 3 again through the Evolution to Einstein i hope

    Apparently, Kepler architecture is simply exploiting the opportunities in the 28nm process, applying the same old Fermi "magic" with some new power managing features. Maxwell should start another new cycle of fresh architectural design all over again.

    I assume you meant Billion. But anyway the right comparison would be to GF114. It has 80% more transistors than GF114 (1.95 Billion), and about 70-80% more performance.

    Thanks!

    On one of the slides they mention "8 Geometry Units". But I see only 4 GPC's?

    On paper, the process is supposed to be 40% better (faster transistors). It's a HKMG process vs bulk.

    The big question is not why is it so good, it's why Tahiti sucks so much.
