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 ESTBattlefield: Bad Company 2
Now approaching a year old, Bad Company 2 remains as one of the cornerstone DX11 games in our benchmark suite. Based on the Frostbite 1.5 engine, it will be replaced in complexity by the DX10+ only Frostbite 2 engine (and Battlefield 3) later this year. As BC2 doesn’t have a built-in benchmark or recording mode, here we take a FRAPS run of the jeep chase in the first act, which as an on-rails portion of the game provides very consistent results and a spectacle of explosions, trees, and more.
Bad Company 2 is another game where the 6670 delivers technically playable performance at 1680. Given that it’s a first person shooter it might be reasonable to drop down in resolution and/or quality to keep the entire experience smooth, but it’s playable. Indeed of the cards we test at 1680, it’s the slowest card we’d call playable.
In any case, depending on the resolution the 6670 has a 12-14% lead over the 5670, while the 6570 trails the 5670 by as little as 2%. Everything here is well ahead of the GT 430 and other slower cards, but well behind the GTS 450 and faster cards. Turks fits in very well between GF108 and GF106, it would seem.

Our primary focus on reviews is for the North American market. I'm not sure about Europe and Asia, but in North America the 6450 does (did?) not go on sale in retail until today. It has been available to OEMs for a couple of months however.mino - Tuesday, April 19, 2011 - link
Even ignoring your global audience, if a card was available for MONTHS in the OEM channel, calling it "paper launch" is absurd.But; who pays, he gets. :(

Consider opening an European branch. Many of us do not agree with many things in the reviews.Targon - Tuesday, April 19, 2011 - link
If a game is CPU limited after that many years, that hints that the game is not multi-threaded by design. Both Intel and AMD have really been more focused on multi-core designs, rather than really pushing the performance of individual cores. Yes, there have been improvements, but it has not been the real focus of CPU development. AMD looks to be working on getting the core design improved to be more competitive with Intel, but that is pretty much it at this point. Going to a 32nm CPU design should also help.vavutsikarios - Tuesday, April 19, 2011 - link
I guess it's not really multithreaded, and even if it is, it definitely won't use more than 2 cores. Afterall, it's a 2005 game. But this is besides the point. The game is CPU limited because of its nature. It is not a design flaw or anything. To clarify: the CPU is the limiting factor not from a performance POV but from a gaming experience POV. After you do whatever you have to do you click the "end turn" button. Then you have to wait for the AI to make their move. This takes awhile. It was minutes, worst case, on the PC I had when I first played the game, it may be less than a minute on the 3GHz quadcore I use now. Still, in order to have smooth gameplay, I need this to become 100x faster.SlyNine1 - Wednesday, April 20, 2011 - link
Thats like saying ChessMaster is CPU limited. Or saying Every game out there is HDD/SDD limited. Yes you will have to wait for complexe operations, but it doesn't interfer with gameplay. Because of that its hard pressed to say its CPU limited, as It doesn't limit gameplay.vavutsikarios - Wednesday, April 20, 2011 - link
I understand what you re saying. The CPU speed, at these levels of CPU performance, doesnt interfere with the functions of the game, that is true. But it does affect the gaming experience. Imagine having to wait a couple of hours for the AI. Wouldnt that be really frustrating? More than that, wouldnt it render the game unplayable? The way you define gameplay, having to wait any amount of time doesnt matter. So, I guess, it is a matter of semantics, of definition of what gameplay is.In the broader sense, which, IMHO, is what matters, things like that are important. They directly affect the pleasures we make for ourselves in the precious little time we have. So, yes, obviously, Every Game out there is HDD Limited! -nice line that one :)
Btw: Chessmaster is not CPU limited, although it should be. It is not though, because having to wait for your opponent to move is part of the normal chess experience. Truth is, chessmaster moves way too fast sometimes, and sometimes it thinks a lot when what it has to do is obvious, but still.

CPU limited on an i7-2600k Sandy Bridge? Or CPU limited on the cpu you bought 6 years ago to play Heroes 5?vavutsikarios - Tuesday, April 19, 2011 - link
See my reply to Targon above. An i7-2600 Sandy would probably be a nice improvement over my phenom2, but still a long way from not being the limiting factor.
