One of AMD’s regional AIB partners, Yeston, is preparing a radical new non-reference design – a Radeon HD 5770 X2. As the name suggests, it is a dual GPU product based on two Juniper XT. This brings the total specifications to 1600 SP, 80 TMU and 32 ROP – identical to Cypress. It features the dual-128 bit memory, the standard 850 MHz core and 4.2 GHz memory clock.

The dual-GPU interconnect is not served by Crossfire, but with Lucid Hydra. Amazingly, the card features a single PCI-e connector which at first seems impossible. The single HD 5770 has a TDP of 108W, and doubling up will surely cross 150W.

The timing of the Yeston HD 5770 X2 is rather strange – coming in with the Radeon HD 6000 series. With the HD 5770′s price dropping, this could be a novel way of “stock clearance” by offering two Juniper dies instead of one in a single package. It could be available at a very reasonably priced card offering HD 5850 levels of performance. Unfortunately, since Yeston is a China regional AIB, the HD 5770 X2 is unlikely to be on sale outside of Asia.
