Synthetics

As always we’ll also take a quick look at synthetic performance. The 270 series is based on the same Pitcairn GPU we’ve come to know over the last year and a half, so there shouldn’t be any surprises here other than slightly better performance.

Synthetic: TessMark, Image Set 4, 64x Tessellation

Tessmark sees tessellation performance rise with the clockspeed increases and then some. For whatever reason the 270 actually jumps the 7850 by a larger margin than we’d expect, improving on its predecessor by 25%.

Synthetic: 3DMark Vantage Texel Fill

With Vantage’s texel fill test, we can see the impact of higher clockspeeds, and in the case of the 270 also the additional enabled CUs.

Synthetic: 3DMark Vantage Pixel Fill

Finally, our pixel fill test is almost entirely memory bandwidth bound on Pitcairn. As a result the performance gains are quite significant, in line with the memory bandwidth increases afforded by the faster 5.6GHz memory.

    What!...no hatchet job on these new cards from Wreckage?
    The hurt just keeps on coming eh Wrecky?

    It's not beating the 760 so his stocks are safe... for now. Besides, you need to give him a break. Poor man must be tired after the release of the 780Ti and 290/X. Reply

    Would really have liked to see CFX numbers. Reply

    Agreed, i need to compare 270X crossfire performance/heat/noise to a single 290X.
    Right now i'm hesitating, for my 3 monitor setup:
    1. Dual 270X for 400$. -Advantage of lower cost, lower heat, lower noise, turn off one GPU when not gaming. Don't know if it's strong enough for 3600X1920.
    2. Single 290 for 450$. -Best price/performance, noisy, hot.
    3. Single GTX 780 superclocked for 530$. - If only for Nvidia cooler and energy efficiency, else i'm an AMD guy.
    4. Single 290X for 550$. -I would pick this over vanilla 290 for chip binning, it should have higher quality GPU as far as energy concumption goes.
    Titan and 780ti are above my budget.

    I'm strongly doubting two of these would game at 3600x1920 comfortable. That's almost 4k resolution. Remember that any AMD card below the 290 series still uses the Crossfire bridge and can't transfer 4k resolution frame buffers through it. Making the second card completely useless as the buffer is just dropped instead. And I haven't seen technical info yet, but I wonder if that's part of the reason why the 290 series outperforms the 780/780 Ti in 4k gaming so well. Perhaps the SLI bridge is also becoming a bottleneck, depending on how it handles frame buffers.

    For that resolution, personally I'd say waiting for aftermarket 290s and 290Xs would be a good choice. Get either much better binned chips in a high end aftermarket 290 or 290X, better thermals, and acoustics for both (and thus better overclocking headroom). With the performance those cards were getting at 4K gaming, they could probably handle single card 3600x1920 at decent settings, though probably not highest without dropping significantly below 60 FPS. But it leaves room for adding a 2nd card, whereas starting with 270X doesn't. Looks like it only has 1 Crossfire bridge which means you can't add a third card.

    Good advice. I'll discard option number 1 then, and yes i'm waiting until we see custom coolers on the 290 series before i make a move, probably an MSI one to match my MB. Although that Nvidia cooler is cool looking as hell.....

    At "3.5K", i find that disabling AA or adjusting just a step below "ultra freaking high details" makes all games playable. By playable i mean above 30FPS.

    Where is the noise equalization test?
    It looks like the asus card is around 853% faster than the nearest competitor.

    Ryan, will you be adding the results from the various R7/R9 models tested in the last month or two to Bench eventually? The entire new series is absent so far, as is the GTX 780 Ti. I often use Bench for comparing my current card to potential upgrades, so it would be great to have. Reply

    Yes. GPU14 Bench will be up next week; I need to clean up the DB a bit first. Reply

    So how come no mention of the 7950 in the conclusion? It's clearly the right choice, as you get 3GB of VRAM in addition to superior performance, and all for a price well under $200. Reply
