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

BattleForge
BattleForge is EA’s card-based online-only RTS. As the first DirectX11 title it’s of particular importance for the latest rendition of DirectX, although in this case we aren’t using any features that would be impacted by it. Even without ambient occlusion, BattleForge manages to be a rather punishing game for GPUs.
BattleForge is another game that punishes the 5700 series. The performance hit coming from the 4870 starts at 25% at 1680, and ends at just 18% at 2560. This also means that the 5770 loses to the GTX 260.
As for the 5750, it loses at 1680 by 7%, but eeks out a very slight win at 1920. Apparently being memory bandwidth starved isn’t so bad when your competitor is too.
Finally, this gives us one of the larger gaps between the 5770 and 5850. $100 buys you 60%-70% more performance.

With any luck they'll become plentiful in a short space of time, offering early adopters the chance to set up a decent EF, umm, setup.If you think the typical EF setup will be two or three monitors, do you expect the full six monitor glory with an X2 part? I'm still wondering if even the 5870 can handle three monitors and still offer smooth gaming performance. That said, despite their power they're not going to strictly be gaming cards.

the fact that this cards consume little power is irrelevant when you have that great efficiency on the 5800... also including the Eyefinity gimmick here is a mistake, it only diminishes the value of that feature on the 5800. It should have been 1 card. HD 5770:no Eyefinity, 800 SP, 750MHz, 512MB = $99 USD

Eyefinity (EF) will be in all 5xxx products for a multiplicity of useful reasons, many of which aren't apparent yet. There will be frequent roll-outs of new EF goodness. There will be many, many customers who will find EF very useful. Hopefully you will realize what EF can do for you and buy one of our products. We'd like for you to be a happy customer of ours.CarrellK

" It should have been 1 card. HD 5770:no Eyefinity, 800 SP, 750MHz, 512MB = $99 USD "
Close, but no. 1GB of VRAM is mandatory anymore, and it needs the 256-bit bus or more texturing units and ROPs. And then it could be $125.

Something's wrong when two of these in CrossFire can't match a single 5850. Blah.qwertymac93 - Tuesday, October 13, 2009 - link
why no mention of 4770? i know its older and slower, but its also 40nm like the 5750 and is the same price, it would be nice to see the difference between the two as they are specked quite closely(640sp@750mhz, 720sp@700mhz, both 128bit gddr5)snarfbot - Tuesday, October 13, 2009 - link
legion hardware has a good review comparing them both.the 5750 is between 1-3 fps faster.
the 5750 has better overclocking potential thanks to the ram i guess, but im not sure if its worth the extra 25 bucks.
kinda a wait and see thing for this part

Yet another good reviews from AT, thanks Ryan. However, it becomes clear cards like HD5870 and HD5770 isnt a very good performer for its price. HD5850 and HD5750 512MB repeesents a more solid bang for bucks. Again its very amazing that AMD has been able to bring us so many next gen DX11 cards when Windows 7 isnt even launched yet and their competitor is being super slow by onli recently releasing a non high end part of G200 derivatives. That being said, from the point of view of solely performance, Cypress and Juniper is kinda a disappointing performer for its price, as well as for its specifications.pullmyfoot - Tuesday, October 13, 2009 - link
Hmm. I was expecting the 5770 to perform either at the 4890 levels or slightly slower at very least while running cooler and taking up less power. This is quite disappointing. I was all ready to get one to replace my 4850 if the price was right. I wonder how well they can tweak the drivers for this thing.yacoub - Tuesday, October 13, 2009 - link
Same here, although I'd replace my 8800GT with it. I expected about 25% more performance, and about $10 less MSRP ($150).
