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.

Because people are impatient and need instant gratification. This happens everywhere...erple2 - Wednesday, October 14, 2009 - link
That, and people walking into stores to buy computer equipment aren't generally looking for the best deal.Ananke - Wednesday, October 14, 2009 - link
I respect the MONEY :). Wasting money for something that doesn't quite fit my intention is not my way. But, people are different, I guess not everybody would do the same...My point is, better pay and get what you exactly want and need, otherwise later you'll regret. Now, if you have so much money to waste, buy anything :) that's different story.5770 with that anemic 128bit bus is worth less than $100, in my opinion. Above $100 it is just wasting money for getting nothing :)

Thing is, people shopping for a new card probably do not have one of the latter cards.. or what they do have is fairly sub par. While they may have a good idea what they'd like to get...... alot of times you see them settle. Hell even those among us who are tech savvy have done that from time to time. Seems to me that's sort of what Nvidia's doing right now.

I need a new card, I want it to be DX11, but the performance isn't there. I want something about 10 percent faster than a 1GB 4870 for about 150 bucks, and something about 10 percent faster than a 4890 for less than 200 bucks; with DX11. Once I see a card like that, from AMD or Nvidia; I'll buy it. Stupid X1650Pro is REALLY limping along in modern games and I'm starting to get sick of low res and min settings.Ananke - Tuesday, October 13, 2009 - link
Really good cards.....not worth the money though :)Did I just summarized it well ?

it would be nice to see some benches with crysis w/o aa.if they really are bandwidth limited that would make the difference.
also overclocked performance, if the memory is the limiting factor then the 5750 would probably be a pretty good bang for the buck.

The HD 5850 was "wow". The HD 5770 is a little "meh". Its great you have something that sits between the HD 4850 and HD 4870 in performance with such low power requirements and noise, but that price has to come down.silverblue - Tuesday, October 13, 2009 - link
I view the 5770 as a natural successor to the 4770/4830/4850 (so I wouldn't expect a 5830 to appear, for example) as opposed to a replacement for the 4870. By now I'd expect 40nm yields to be much better than a few months back when TSMC had issues producing the RV740 variants so hopefully any dies that are defective are only minimally so and ATI can put them on the 5750 cards. Makes me wonder about the lower-range cards due next year though.The Eyefinity ports are an enigma, however it could make for a very nice business class card assuming anyone can afford those dongles.

If you are building an Eyefinity (EF) setup, you prolly don't have three monitors. You prolly have one or two. This means you will be buying at least one monitor. My advice: buy a DP monitor that matches the physical size & resolution of your existing monitors. That way you don't need to get an adapter.CarrellK
