The Inquirer claims to have some good knowledge of the upcoming R580 specifications include a 695 MHz core clock and 1550 MHz memory clock!
OUR CHINESE colleagues have reported that R580 comes in a couple of flavours and our Theo wrote about this before. But this time these guys have a picture of the actual hardware and have some of the clock details. The card looks very much like the previous R520 based chip. It comes at very similar clock speeds, or should I saw at almost identical speeds to X1800XT OC cards that are still missing in action, except Asus that already has them ready.
