The upcoming ATI R600 GPU from AMD will only use GDDR4 memory, The Inq reports:
In the end, Nvidia went with GDDR-3 memory in its G80 line-up, but ATI continued to develop both GDDR-4 (Pele) and GDDR-3 (UFO) variants. Being late on the market enabled ATI to optimise. However, bean counters at AMD recently gave a "go ahead" signal for full-GDDR-4 line-up. So, forget about the dual-SKUs, 1Gig and 2Gig versions, GDDR-4 is the only way DAAMIT will go .
Memory layout remains the same, as does the GPU. The chip itself is rotated at 45 degree angle – not the 60 degree this tired hack wrote a week ago. Also, the chip whose pictures were leaked was not a functional chip, but rather a mechanical "dummy".
