The Radeon HD 5870 Eyefinity 6 is clocked at the same 850MHz core/1200MHz memory as the original card, but with the added memory comes a higher power draw as the Eyefinity 6 board's max TDP increases to 228W. That's 40W more than the Radeon 5870 1GB, but still a fair bit lower than Nvidia'a 250W for the GeForce GTX 480.
To accompany the announcement Asus released its own take on the card and called it the Republic of Gamers 5870 Matrix. As the ROG branding suggests, you can expect some souped-up specs compared to AMD's reference design. Although the memory runs at a standard 4,800MHz, the GPU is pre-overclocked to run at 894MHz, and Asus' Super Hybrid Engine (SHE) will reportedly deliver an average performance boost of 19% whilst gaming at high detail.
Providing the overclocking crowd with a little extra control, Asus has included independent voltage controllers and card-mounted voltage measurement points, as well as a custom cooler that promises greater air flow and temperature drops of at least 13% compared to AMD's reference design. No pricing or availability has been announced.
