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

Batman: Arkham Asylum
Batman: Arkham Asylum is another brand-new PC game, and has been burning up the review charts. It’s an Unreal Engine 3 based game, something that’s not immediately obvious from just looking at it, which is rare for UE3 based games.
As Batman: Arkham Asylum implements anti-aliasing differently between AMD and NVIDIA cards, this is the one title that we do not test AA on, as doing so produces results that can’t be compared.
The 5770 goes back to losing by a wider margin compared to the 4870, roughly 10% this time. The story of it compared to the GTX 260 is also the same, with another GTX 260 win.
Meanwhile the 5750 gets another win over the 4850, although this is one of the only times it loses to the GTS 250.
Finally, a 5850 will buy you another 45%-55% in performance, for $100.

That may be due to some architectural improvements in the 5770's shaders. The drop in performance in other games may be due to the decreased memory bandwidth, which may not matter with regards to Far Cry 2.papapapapapapapababy - Tuesday, October 13, 2009 - link
this cards are super lame... 5750, now with +80 stream processors ! XD that 5750 is basically a ( lower clocked!) 4770... guess what ati? that cost me $85 bucks 6 months ago! but who cares right? nvidia is dead so why bother? just slap a dx11 sticker, rice the price ati?The0ne - Tuesday, October 13, 2009 - link
Just wanted to say I like the conclusion and it's dead spot on on the suggestions and advices.I'm very surprise almost no one is talking or bringing up the subject of DirectX. DX11 has more chance to succeed yet less attention. It's amazing how badly DX10 was to sway consumers about face.

The problem with DX10 was that you had to buy Vista to get it...MadMan007 - Tuesday, October 13, 2009 - link
DX10 rendering paths of games that were also DX9 (meaning all of them at the time and even now) were also *slower* and provided little to no i.q. improvements. So even if it hadn't been Vista-only (and only morans keep on with the Vista FUD after SP1) there was no real benefit. DX11 looks to be different in all respects.Lifted - Wednesday, October 14, 2009 - link

Quite strange that with die size 166mm2 againts 260mm2(rv770) and with 128bit memmory it costs this much. And the 5750 has disabled one simd which even increase the amount of usable chips (but maybe its disabled just for the diference or else the two cards would be exatly the same except clocks).The Tessellation part with fixed units is exatly the same as 5800 series or tuned down ?

I chalk it up to lowish 40nm yields at TSMC.Spoelie - Wednesday, October 14, 2009 - link
+ higher cost per wafer as a 55nm one+ ddr5 prices

Unless you absolutely need to take advantage of the lower power requirements of the 40nm process (e.g. you pay a ton for power)...According to your tests, the 5770 consumes a whopping 48W less idle power than the 4870, and other reviews have comparable results. If your computer is out of standby a modest 10 hours a day, that works out to 175 kWh per year. That's easily $15/year even for people with cheap electricity.
The funny thing is that I usually see people overstating the savings from power efficiency...
