I'm looking forward to this card, will put G92 to shame IMO and I hope it can help AMD out of their current situation. This card and the recently released 780G chipset and Phenom 9850 could be the products that will bring AMD back. I might pick one up if the benches are good.
"while the 4870 will be the first mass-production GPU with a clock speed higher than 1 GHz. Prototype RV770 boards were clocked at about 1.05 GHz. "
"Both GDDR3 and GDDR5 memory will be supported by the chip, but ATI itself will only be offering GDDR5 cards"
"The graphics processor itself will integrate more texture memory units (TMUs)"
"With a 256-bit memory controller, we’re talking about 115 to 141 GB/s of bandwidth. This number equals the memory bandwidth record set by the 2900XT 1GB GDDR4 (512-bit interface with GDDR4 at 1.1 GHz DDR)."
"but we were told that the GDDR5 memory is currently running at a physical clock of 1.8 - 2.2 GHz."
