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.

    It's like different people work on different products! Reply

    A commandment of any cell phone reviews, thou shall not rush battery life tests. Reply

    Be thou particularly careful testing battery life when thine available anecdotes vary wildly. Be thou definitive. Reply

    I may not read the article very carefully, and I keep wondering that why 280X has a star behind it. Reply

    I'm getting a little tired of this TDP nonsense. Two cards with the same TDP from the same product family of the same manufacturer that clearly consume different amounts of power - the TDP numbers are now meaningless. And don't get me started on Intels SDP. Reply

    If both are under 150W, then where is the problem? Maybe R9 270 consumes close to 130W-140W and not 150W, giving the necessary room to AMD's partners to oc the chip without passing the 150W limit. Reply

    OCed 270 is 270x Reply

    Under 150W means it only needs one 6-pin power connector (like the 7850 or 660 which it replaces/competes with) and in general is much more power-efficient. The 270 (non-x) is aimed more at builders with power limits or old systems that can't support a dual-6-pin GPU, or perhaps computational tasks where performance per watt is more important than performance per card. The 270x is full-powered but less efficient and is better suited for gamers and tweakers. I wouldn't get a 270 to save $20 unless the lower power limit was important, in which case it's actually a good buy, as it should still edge out a gtx 660 while staying under 150W total power. Reply

    SDP at least makes sense. Reply

    quick comment on the DCUII coolers from asus. I too have been very impressed with them. my goal was silent yet powerful computing, and the DCUII cooler on my GTX670 plays that part admirably. Reply
