Synthetics

As always we’ll also take a quick look at synthetic performance to get a better look at our video cards' underpinnings. These tests are mostly for comparing cards from within a manufacturer, as opposed to directly comparing AMD and NVIDIA cards.

We’ll start with 3DMark Vantage’s Pixel Fill test, a mix of a ROP test and a bandwidth test to see if you have enough bandwidth to feed those ROPs.

Synthetic: 3DMark Vantage Pixel Fill

Moving on, we have our 3DMark Vantage texture fillrate test, which does for texels and texture mapping units what the previous test does for ROPs.

Synthetic: 3DMark Vantage Texel Fill

Finally we’ll take a quick look at tessellation performance with TessMark. We have everything turned up to maximum here, which means we're looking at roughly 11 million polygons per frame.

    Not at 176GB/s, unless they're clocking that GDDR5 VERY high. The 7790 is good for 96GB/s. Reply

    Sony's previous two consoles (PS2 and PS3)have traditionally favored high frequency/bandwidth proprietary Interconnects between components (see Cell's EIB) so this is likely where the "secret sauce" Sony R&D came in, thus facilitating the 176GB/S.
    AMD was quoted (can't find link) that said Sony engineering would be excluded if/when they release a PC variant of said APU.

    Very, very interesting indeed. It tallies well with the numbers. There was me thinking they had bolted Pitcairn onto the side of their CPUs but this combo might make more sense (and yet also less sense). Reply

    Totally agree with memory size. At this performance and price level, 2 GB should be default. Reply

    Then again, it would be strange if AMD doesn't release "larger" cards based on this updated GCN core. Reply

    Perhaps the reason for the lack of a 2GB version would be that it would be too close to the 7850...? Reply

    NO it SLOWS THE CARD DOWN with it's crappy amd core...
    Haven't you been paying attention for like the YEARS you've been here ?
    My apologies if you're an epileptic.

    I don't understand why you haven't been banned yet. You add nothing to the discussion with your posts other than vitriol. Please either be civil and logical, or go away. Reply

    AMD always releases 1GB models and 2GB models so the amd fanboys can quote the 1GB model cheapo powercolor low end price, claim it wins price perf, then go on raging about how the 2GB model covers the high end ...

    ROFL - That's what they do - they even do it when comparing to a 2GB nVidia, suddenly forgetting amd makes crapster 1GB they swore off years ago, even though that's the screamer amd fanboy price "they pay" because "it's such a deal! Man! "

    Brainfart Bart they should be called.

    Actually, they didn't with the 7770.

    Your constant whining is about as welcome as a bout of herpes, scram.
