High-end models will deploy the full array of 16 Cluster A total of 512 CUDA Core computing unit, to support 384-bit GDDR5 memory body structure, body has a memory capacity of 1.5GB.Fermi 40nm 250W / 300W PCI-E 6-pin + PCI-E 8-pin Although the Fermi core has adopted 40nm manufacturing process, provided that such cards power up to 250W to 300W, and called for PCI-E 6-pin + PCI-E 8-pin power supply. 2 Cluster 1 448 CUDA Core 320-bit GDDR5 1.28GB 225W PCI-E 6-pin A second level model will take away the two Cluster group memory array and a body controller, which fell to 448 CUDA Core and 320-bit GDDR5, memory body with a total capacity of 1.28GB, power consumption is reduced to 225W, and only need two PCI-E 6-pin power supply.
