Yeston gives birth to Radeon HD 5770 X2
Basically it is two Radeon HD 5770 video cards, based on 40 nm Juniper GPU, that are linked via PLX-made bridge chip.
China regional AIB, Yeston, has introduced its new product — Radeon HD 5770 X2 Graphics Card. Basically it is two Radeon HD 5770 video cards, based on 40 nm Juniper GPU, that are linked via PLX-made bridge chip. Therefore, the product features doubled specs: 2×1 GB of GDDR5, 2×128 bit memory, 2×800 SPs, 2×40 TMUs, 2×16 ROPs. GPU and memory clocks are the same as the original HD 5770 has: 850 MHz for core, and 1200 MHz (4800 MHz GDDR5 effective) for memory.
Both GPUs are located on a single PCB of non-reference design and operate in tandem via an internal CrossFire interface. The graphic card has 4+1 phase VRM followed by additional power drawn from ONLY ONE! 6-pin PCI-E power connector. However, there is no exact info on power consumption. But we assume it can be greater that 150W since reference-design HD 5770 has TDP of 108W.
The back of the PCB hold the PCI-Express bridge chip, while memory chips are located on both sides. It is clear that this card can also operate with another Juniper-based graphics card in multi-gpu CrossFireX mode.
The cooling systems features two 90 mm fans with a large heatsink making it a dual-slot graphic card. The display connectors includes two DVI, one HDMI, and a DisplayPort.
As Radeon HD 6000 series are coming to the market soon, the HD 5000 series will definitely see the price cut, which will make HD 5770 X2 Graphics Card (with performance level of HD 5850) a good bargain. On the other hand, Yeston is not likely to have HD 5770 X2 sold in US but in Asia.
