AMD implemented its plans to rebrand Radeon HD 5700 series to HD 6700 series, by listing up Radeon HD 6770 and HD 6750 on its website. For now, it's available only to OEMs. There are no changes between the 5700 and 6700 as far as specifications go, except HDMI 1.4a support. At most, you can see a different-looking cooler shroud on the reference-design graphics cards. Other than that, they're the same. The HD 6770 is based on the 40 nm Juniper silicon, with 800 VLIW5 stream processors, and 1 GB of GDDR5 memory over a 128-bit wide memory interface. The HD 6750 on the other hand has 720 stream processors. There's no information at present on when (or if) AMD plans to release this to the consumer market.
