10 GCN Compute Units on Cape Verde XT site has come up with a full specification list for the upcoming AMD Radeon HD 7700 series graphics cards based on the 28nm Cape Verde GPU.

The Cape Verde GPU itself is based on 28nm GCN architecture and features 10 Compute Units clusters with 64 shader units and four texture units per cluster for a total of 640 Stream Processors and 40 TMUs as well as 16 ROPs. The GPU will be tied with 1GB of GDDR5 memory paired up with a 128-bit memory interface.

According to the post, the Radeon HD 7770 should pack a fully enabled Cape Verde GPU so it has 10 CUs and 640 Stream Processors and is set to work at 1000MHz for the GPU and 1125MHz (4.5GHz effective) for the memory. The TDP should be somewhere around 80W, which means that HD 7770 will end up with a single PCI-Express power connector after all.

The Radeon HD 7750, based on the Cape Verde Pro GPU will lack two CUs, so it will end up with 8 CUs enabled for a total of 512 Stream Processors. The rumoured clocks are set at 800MHz for the GPU and the same 1125MHz (4.5GHz effective) for the same 1GB of GDDR5 memory paired up with the same 128-bit memory interface. The TDP for the HD 7750 is set at around 55W so it should be quite happy with the 75W provided by the PCI-Express slot.

These specs are pretty much on par with what we have been hearing around and the expected performance, according to the post, should be somewhere around the HD 6850 for the HD 7770 and somewhere around HD 6770 for the Radeon HD 7750. The price for the HD 7770 is rumoured at around €115 while the price for the HD 7750 is set at around €90 to €100.

Cape Verde is still scheduled to launch on February 15th as far as we know and we are sure that there will be a leak or two in the upcoming five days. You can check out the original post here
