Spec wise, the Radeon HD 6770 features 800 stream processors, 40 texture units, 16 ROP units, a GPU clock of 850MHz, a 128-bit memory interface, and 1GB of GDDR5 video buffer that is clocked at 1200MHz (4800MHz data rate). These changes were made possible by the fact that HDMI 1.3 and HDMI 1.4a both have the same bandwidth requirements, while the 6700-series cards are fast enough to process MVC if the video decoding clocks are slightly increased.Īs these features are implemented in the card's BIOS, so there is a possibility that these could also be enabled on the HD 5700-series card via a BIOS flash.
Thanks to these changes, the Radeon HD 6770 and HD 6750 are now HDMI 1.4a compliant and support some of the additional resolutions and bitrates required by Blu-Ray 3D’s MVC(H.264) profiles. The two cards features the same specifications, clocks, power requirements and PCB designs as their Juniper counterparts since the modifications brought by AMD were limited to the card's BIOS. The leaks regarding AMD's plans to launch the OEM-only Radeon HD 6700-series graphics cards into the retail market have come true at last as the company has now announced the introduction of the HD 6770 and HD 6750 GPUs that are just rebranded versions of the previous HD 5700-series.
