A leaked slide tipping AMD's next generation "Tenerife" GPU found its way to the Web (funny how that always happens), and it's a beast. As part of AMD's Sea Island based HD 8000 Series, the Tenerife part is a power user card that will dethrone the HD 7970. We'll go ahead and call it HD 8970, with the understanding that this isn't the official name (yet).
The proposed 8970 card is said to have 2,304 Stream Processors, 128 TMUs, and 48 ROPs. Clockspeeds are unknown, but it will be capable of more than 4.5 TFLOPS of processing power and 20 percent more compute performance than the current flagship part.
Other features include 3GB of GDDR5 memory racing along at 6GHz on a 384-bit bus, two mini DisplayPorts, an HDMI port, and DVI connectivity. TPD will be 250W.
