At the beginning of April, Jarred walked us through the refresh of the bottom two-thirds of NVIDIA's 700M series of GeForce GPUs, all under the GeForce GT heading. We still didn't have any idea what their solutions at the top end would be, though. Today we have those details with the launch of the GTX 700M series. GTX 660M GTX 760M GTX 670MX GTX 765M GTX 675MX GTX 770M GTX 680M GTX 780M GPU* GK107 GK106 GK104 or GK106 GK106 GK104 or GK106 GK106 GK104 GK104 CUDA cores 384 768 960 768 960 960 1344 1536 Base Clock 835MHz 657MHz+ 600MHz 850MHz+ 600MHz 811MHz+ 720MHz 823MHz+ Memory Clock 4GHz 4GHz 2.8GHz 4GHz 3.6GHz 4GHz 3.6GHz 5GHz Memory Bus Width 128-bit 128-bit 192-bit 128-bit 256-bit 192-bit 256-bit 256-bit Memory Config 2GB GDDR5 2GB GDDR5 3GB GDDR5 2GB GDDR5 2GB/4GB GDDR5 3GB GDDR5 2GB/4GB GDDR5 4GB GDDR5 Note that the 680MX (not listed) exceeded the 100W TDP and was never made available in notebooks; it was an iMac exclusive GPU. Spec-wise it was identical to the 780M, but had a slightly lower core clock at 720MHz. That means...
