Yeston has designed a Radeon HD 5770 X2 card that features two Radeon HD 5770 chips with 1GB GDDR5 per GPU. At first sight it looks like the company is a bit late to the party, but considering that AMD decided to rebrand the Radeon HD 5700 series to Radeon HD 6700, the company may have a chance to sell a few of these cards as Radeon HD 6770 X2 parts.
The card features a PLX-made bridge chip, 4+1 phase VRM, just one 6-pin PCIe power connector, and a large heatsink with two 90mm fans. The two cores feature a 850MHz clockspeed and the GDDR5 memory has a frequency of 4200MHz. Outputs include dual-DVI, HDMI and DisplayPort.
