Some leaked info about AMD's HD7 series: HD7800 series (Thames) 1536 VLIW4 @ 950mhz, 2GB GDDR5 @ 5800mhz (256-bit, 186GB/s), 120W TDP (HD7870) 1408 VLIW4 @ 850Mhz, 2GB GDDR5 @ 5200mhz (256-bit, 166GB/s), 90W TDP (HD7850) compares to HD6900 series (Cayman) 1536 VLIW4 @ 880mhz, 2GB GDDR5 @ 5500mhz (256-bit, 176GB/s), 210W typical (250W max) (HD6970) 1408 VLIW4 @ 800mhz, 2GB GDDR5 @ 5000mhz (256-bit, 160GB/s), 170W typical (200W max) (HD6950) HD7670/HD7570 (Lombok) 768 VLIW4 @ 900Mhz, 1GB GDDR5 @ 5000mhz (128-bit, 80GB/s), 60W TDP 768 VLIW4 @ 750Mhz, 1GB GDDR5 @ 4000Mhz (128-bit, 64GB/s), 50W TDP compares to HD6700 series (Juniper) 800 VLIW5 @ 850Mhz, 1GB GDDR5 @ 4800mhz (128-bit, 76.8GB/s), 108W TDP (HD6770) 720 VLIW5 @ 700Mhz, 1GB GDDR5 @ 4600mhz (128-bit, 73.6GB/s), 86W TDP (HD6750) HD7900 series (Tahiti) 2048 GCN @ 1000Mhz, 2GB XDR2 @ 8000mhz (256-bit, 256GB/s), 190W TDP 1920 GCN @ 900Mhz, 2GB XDR2 @ 7200mhz (256-bit, 230GB/s), 150W TDP It's becoming pretty apparent that the switch to 28nm will offer HD6950/6970 performance including the memory capacity and bandwidth on a single PCIe 6-pin card. Here's hoping the pricing will be similarly low. The performance of the HD7900 series however, isn't immediately guessable, as it's a new architectural design, and new memory type as well. Theoretically we should be looking at something of the order of a 40% performance increase against a 10-20% power reduction. Not bad, but once again AMD are pretty conservative with the new architecture here, presumably because the silicon yields will once again be very low, causing availability to be very poor, much like the HD5 series. Once again, nvidia are several months behind at this stage with Kepler, but with a later release date this time around, it's difficult to say if AMD will get much of a retail headstart, if any.
