AMD’s Radeon HD 5770 & 5750: DirectX 11 for the Mainstream Crowd

Resident Evil 5
As is often the case with console ports, the latest installment of Capcom’s popular survival horror series is not particularly GPU starved, and can crank out high numbers on just about anything.
The 5770 goes back to losing, but this time it’s only by a few percent. The GTX 260 wins here yet again though.
It’s another win for the 5750 though; 6-10%. It and the GTS 250 are virtually indistinguishable above 1680.
Finally, another $100 on a 5850 buys you 40%-50% more performance.

What in the world is going on with this game? 8800 GT beats the 4850? No, sorry, I don't buy that. Something is wrong here. The 5770 beats everything? If that is the case, then this game should immediately be removed from the bench suite - games in the bench suite should help us understand the general performance characteristics of the hardware and a game that returns such erratic results actually distorts that understanding.Griswold - Tuesday, October 13, 2009 - link
On page 13 you say:"The 3870 beats it by 14W at the cost of a significant degree of performance, while the 8800GT is neck-and-neck with the 4770, again with a decent-sized performance gap."
You certainly meant 5770 there. But this brings me to a question: Why isnt the 4770 included here? As an owner of that card, I'm very much interested in the performance/power/noise difference - just ditch one of the relatively irrelevant SLI or CF combos. I dont think too many care about comparing high-end multi-GPU with performance parts such as the 5770 and 5750, even if its 57xx in CF.

Ryan - thanks so much for the review. Nice job. It does seem like a 5750 Crossfire would be an interesting value - moreso than the 5770 since the latter is overpriced.And, Anand, I love your site, and don't take this personally, but, PLEASE GET A COMMENT SYSTEM THAT DOES NOT TOTALLY SUCK!
Check out TechReport for an example of the awesomest comment system in the universe.
PLEASE!

AMD only sent out 1 5750, so I don't have a second one to Crossfire at this time.Roland00 - Tuesday, October 13, 2009 - link
It makes no sense (beside bad drivers) for the 5770 to lose to the 4850. The 5770 has more memory bandwidth (76.8) compared to the 4850 (63.55 gb/s), due to the 4850 sticking with ddr3, even with the 128 bit bus. The 5770 is also clocked 36% faster than the 4850 (850 vs 625).Yet the 5770 underpeforms the 4850 being almost tied?

Maybe the 4*64bit memmory controlers on the perimeter of the chip keep up the data better than 2*64bit controlers with higher bandwith.I think that they could make it at least 192 bit (3*64bit).

Actualy where the hell are the Cypress and Juniper die shots ?I cant find a single one on net.

AMD is not releasing die shots.dgz - Tuesday, October 13, 2009 - link
Looks to me like AMD is trying to lure people into buying the remaining 48** cards. Once the old chips are cleared, the price of 57** will no doubt drop.GrizzlyAdams - Tuesday, October 13, 2009 - link
What really has me concerned is how the 5870 is scaling in these tests.The 5870 core is essentially two 5770s strapped together, and you would hope scaling would be near linear. When two 5770s in crossfire match or even beat a 5870 I'm left scratching my head.
Somewhere there is a significant bottleneck in the 5870's design, and I'm wondering where that is. Anyone have any clue?
Hopefully a driver update will fix these issues, because if not there is a lot of wasted silicon on each of these chips...
