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.

    I'm not sure I like the R9 270. It should have been a cut card ~18CU's. I mean you can edit the BIOS to let up to +50% power limit so the only differentiation of the 270 and 270X (power) can be side stepped rather easily.

    The only hope is the 270X is binned much much higher than the 270 (to the point where the 270's are dogs), else there really isn't that much reason to buy one.

    Also I'm surprised that the ASUS R9 270 wasn't a single 8pin connector.

    A single 8-pin connector would essentially make it a 270X. Reply

    Are you really complaining that the card is not handicapped enough and that you can get a very powerful card for a low price? And you say that you don't like that you can get this card this cheap? Reply

    WTH? Really? That is the dumbest thing I ever heard! That is like getting a million dollars and then saying you should have got less. What is wrong with you?
    I am glad the 270 is just the same as the 270X, I only paid $179 for it, And all I have to do is go into CCC and set my clock from 925mhz to 1050, And bam I got 270X , And with better power efficiency. However I leave it at 925mhz because it has more than enough power to max most games at stock. You can't get a better deal than this right now. Now if AMD can just get their drivers right and keep the artifact problem gone. So far 14.4 stable has no artifacts, But the new 14.6 beta has artifacts in games that require physx, (like Mafia 2) So I just keep 14.4 installed. It's sad that it has been over 2 years and AMD is still having artifact problems in their drivers. This has effected allot of 280/280X users. Some figure out that it is the drivers, And others just returned their cards, It's amazing how nobody wants to admit what the real problem is, It is like they want to worship and praise AMD instead of solving the artifact issue.

    The 270X seems like a pointless card to anyone willing to adjust clock speeds since it is the same GPU as its cheaper sibling, much like the 7970 GHz edition was to the 7970. I remember most 7970s (including mine) easily clocked to 7970 GHz edition speeds with little or no voltage increase. Is the 270 the same in regards to reaching the clock speed of the 270X? Reply

    I'm guessing the difference will be binning. So while you might end up with a 270 that can clock up to (or beyond) a 270X, there's a chance you may not if you were unlucky and ended up with lower quality silicon. Reply

    The difference will be TDP. I think the 270 is already operating near it's power limit. But the 270X has a lot of headroom. Reply

    The right choice would be to get a 7950 Boost for under $200 and skip the 270-series generation which is rebranded lower-level hardware. Reply

    Yeah, the 7950 Boost is a great bargain for now... until the supplies dry up. I managed to grab one for my nephew's new PC for $160 after rebate! It even came with the Never Settle Gold... going to be a great addition to his first PC :) Reply

    I'm not sure if I'm missing the section that points it out, but what does the asterisk behind the 280X in the graphs represent? Does it represent some sort of caveat or warning that we should be aware of? Reply
