Yeston Designs Radeon HD 5770 X2 Graphics Card
Now that AMD seems to have given the 40 nm Juniper GPU (on which are based the Radeon HD 5700 series models) a new lease of life, manufacturers can continue to get innovative with the Radeon HD 5770 GPU. One such board partner, Yeston, designed a Radeon HD 5770 X2 graphics card, which simply put, is a dual-GPU graphics accelerator that makes use of two Radeon HD 5770 GPUs, each with its own 1 GB of GDDR5 memory, that share the PCI-Express interface using a PLX-made bridge chip (perhaps the same one used on the Radeon HD 5970).
The PCB holds both GPUs on the obverse side, the PCI-Express bridge chip on the reverse side, and memory chips on both sides. A 4+1 phase VRM is used, additional power is drawn in from just one 6-pin PCI-E power connector. Both GPUs work in tandem via an internal CrossFire interface, it can pair with another Juniper-based graphics card for 3-GPU or 4-GPU CrossFireX. The duo are cooled by a large heatsink, air is circulated by two 90 mm fans. AMD reference clock speeds (for the Radeon HD 5770) of 850 MHz core, and 1200 MHz (4800 MHz GDDR5 effective) memory are used. Display connectivity includes two DVI, one HDMI, and a DisplayPort. Knowing Yeston's reach, it's not very likely that this card will be sold in the US more towards the Asian market.

I'm supprised at the single 6 pin and size of the card, but i would expect it to have to be cheaper than a 5850 to be that useful as if you only want a single card then it becomes pointless after the price range of a higer powered single card although its low power usage and small size could be a good selling points over a more powerful single slot card if both are limitations within a prospective buyers computer/case.
*edit*beat me to it :p
Also the 5770 - 6770 re-brand story has no official source so it's just a maybe until these cards are released.
Full speed HD 5750 is possible at 62 watts. So full speed of HD 5770 X2 under 150 watts should be possible. Maybe they are decrease voltage on core and memory.
wow, if this thing was priced for $160 then i'm sold
At the right price, it could make me go ATI again :eek:
Shame that it won't be available here though :(
I can't see this being 160 bucks though
On topic....... I just hope that this becomes a success (at the right price point) and therefore other manufacturers adopt it otherwise it will become Sapphire's HD4850x2 which to be fair was a decent card but poorly supported generally...... Choice is always good.
I have to wonder if a dual 5/6770 might cut into the sales of 5830's 5/6850's (and 6830's if they will exsist) though.
It's been well established that barts is a new chip for ages and ages and ages :laugh:
It has a different shader architecture man :laugh:
