AMD’s Radeon HD 6670 & Radeon HD 6570: Two’s Company, Sub-$100’s A Crowd
by Ryan Smith on April 19, 2011 12:01 AM ESTDIRT 2
Codemasters’ 2009 off-road racing game continues its reign as the token racer in our benchmark suite. As the first DX11 racer, DiRT 2 makes pretty thorough use of the DX11’s tessellation abilities, not to mention still being the best looking racer we have ever seen.
DIRT 2 is another game where the 6670 could be playable at 1680 if only it was a bit faster; it can crack 30fps, but it’s certainly not a smooth experience even without AA. The 5750 is 22% ahead here, and it only gets worse from there.
Looking at 1280 however and the performance is much, much higher. Here the 6670 has an 11% lead on the 5670 and 13% on the 6570. Meanwhile the 6570 once again closely trails the 5670, this time by 2%. DIRT 2 has a number of different quality settings, so it should be possible to run it at a higher quality without significantly impacting the performance of the Turks cards.

Just a clarification:. I guess these don't support fp64?Ryan Smith - Tuesday, April 19, 2011 - link
Correct. AMD only supports FP64 on the 5800, 5900, and 6900 series.haplo602 - Tuesday, April 19, 2011 - link
6800 do not ?Ryan Smith - Tuesday, April 19, 2011 - link
Also correct. The 6800 series (Barts) does not support FP64; AMD opted not to include it to save on die space.haplo602 - Tuesday, April 19, 2011 - link
awww so my choices got reduced to the 5850 :-(Taft12 - Tuesday, April 19, 2011 - link
At $150, 5850 is the obvious choice anyway (today - 6570/6670 launch day)http://www.newegg.com/Product/Product.aspx?Item=N8...

Eh. If this is your price point you might as well go with a 5670.Taft12 - Tuesday, April 19, 2011 - link
Not if you want the 6xxx-series features.OzzieGT - Saturday, April 23, 2011 - link
Why? 5670 costs only $5 less on newegg right now and it uses more power. I would rather pay the extra $5 for the newest generation card if it offers the same performance.dagamer34 - Tuesday, April 19, 2011 - link
Don't these cards do AMD 3D? That's the only reason for someone to upgrade a previous HTPC card to something with a Turks GPU.
