Radeon HD 4770 Released, Industry's First 40 nm GPU
AMD today released the ATI Radeon HD 4770 graphics card. The release marks several milestones for the company, mainly winning the race for the first GPU to be built on the 40 nm process, and the introduction second-generation GDDR5 memory for the mainstream consumer segment.
The brains of this card is the 40 nm AMD RV740 GPU. Its specifications include 640 stream processors that churn out over 900 GFLOPs of shader compute power, 32 texture memory units, and 16 render back-ends. The GPU is aided by 512 MB of fast GDDR5 memory across a 128-bit wide interface. This provides the same amount of bandwidth as 256-bit GDDR3 commonly found in most graphics card in the range. The card is DirectX 10.1 compliant, and supports the ATI CrossFireX multi-GPU standard.
The card has been launched worldwide, with its initial US price set at $109, and an optional rebate that can send its price further down. In its range, it competes with NVIDIA GeForce 9800 GT, and AMD's own Radeon HD 4830. TechPowerUp is one of the first technology portals to publish a thorough review of the Radeon HD 4770.

Again...very impressive crossfire performance.
Does anyone know if these are coming in 1gb variants?
A couple of months i suppose there might be custom designs with performance passing 4850 with all the little things that make ocers happy...
:banghead: :banghead: :banghead:
The card could be a supreme 2D IDLE low power contender if they reigned in the memory clocks. Way to go useless PowerPlay! Enable driver-based state switching (like the HD4870X2), and there would be power savings galore.
Well smart users can still do the underclocking themselves. It works but it's not automatic. :(
