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 ESTMetro 2033
The next game on our list is 4A Games’ tunnel shooter, Metro 2033. Metro is quite a resource intensive game, and if Crysis is a tropical GPU killer, then Metro would be its underground counterpart.
Being a GPU killer, the 6670 and 6570 don’t even stand a chance at 1680, so it’s to 1280 we go. Normally we’d classify Metro as being shader-bound, which is why we’re surprised the 6670 only takes a 6% lead over the 5670 and an 11% lead over the 6570. At these settings we’re looking at either being ROP or memory bandwidth bound, with the former being the more likely outcome given that our results closely match the differences in clockspeed. With that said the 5570 is certainly vulnerable to both ROP and memory bandwidth limitations, which is why the 6570 takes a sizable 33% lead.

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.
