The AMD Radeon R9 270X & R9 270 Review: Feat. Asus & HIS
by Ryan Smith on November 13, 2013 12:01 AM ESTSynthetics
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.
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%.
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.
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.

Non-reference. There isn't a reference 280X, so we're using an XFX card as a proxy.garadante - Wednesday, November 13, 2013 - link
Ah, alright. And I also noticed that there's no overclocking section on this review, which is one of the most important aspects of any GPU review for me personally. Is there a specific reason for that?Erenhardt - Wednesday, November 13, 2013 - link
AMD cards cant be overclocked within "out of the box" policy. Contrary to nvidia cards, which overclocks nicely giving free performance for every CUDA user.garadante - Wednesday, November 13, 2013 - link
I don't know what you're smoking Erenhardt, because AMD cards overclock quite nicely. In fact, overclocking AMD cards is currently much more user open because they can be overvolted, whereas Nvidia has locked down on user overvolting. And I have no clue what "out of the box" policy you're trying to mention. Overclocking an AMD card won't void the warranty unless there's damage to the card itself. Please don't try to troll.ddriver - Wednesday, November 13, 2013 - link
Too bad most nvidia gpus suck in compute...Ryan Smith - Wednesday, November 13, 2013 - link
Solely a matter of timing. I have the data, but this launch happened opposite APU13. So it had to be written very quickly.The 270X topped out at 1150MHz Base (1200MHz boost) and 6.5GHz memory. The HIS 270 topped out at 1075MHz base (1100MHz boost) and 6GHz memory. The Asus topped out at 1125MHz (1150MHz boost) and 6GHz memory.

Ah, alright. Thanks Ryan! So unless it's a fluke, the 270X might be slightly better binned than the 270. Are the default BIOS still not allowing for overvolting like most of the 290 series? Or because these are refreshes, is overvolting already possible with current tools without updates?blanarahul - Wednesday, November 13, 2013 - link
How can the GTX 760 beat the R9 280X in Hitman: Absolution?!The Von Matrices - Wednesday, November 13, 2013 - link
It was said in previous articles (but it should be included in all articles that have the 280X in the chart) that there is no reference 280X card or heat sink so the results they are using are from an XFX card with custom PCB and cooling (but stock clock speeds).laskdfjoiewjfalsd - Wednesday, November 13, 2013 - link
For the love of God post the Nexus 5 review already. I come here everyday and see random stuff like this while a flagship is being put off to the side!
