AMD’s Radeon HD 6670 & Radeon HD 6570: Two’s Company, Sub-$100’s A Crowd

Metro 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.
