With Windows 8, 7 and Vista also being DX11.1 ready all we need are some games to take advantage of DirectCompute, multi-threading, hardware tessellation and the latest shader 5.0 extensions.įor your reference here's a quick overview of some past generation high-end GeForce cards opposed to the new Kepler based GeForce GTX 680.įor Kepler, NVIDIA kept their memory controllers GDDR5 compatible. The new graphics adapters are of course DirectX 11.1 ready.

With this release, NVIDIA now has the first series 600 cards on its way. One clock to rule them all (well internally there are dozens of different other clocks really, but let's keep it simple). It's actually similar bandwidth to the GeForce GTX 580.Īn immediate difference to the GPU core versus the shader processor domain is that both will be clocked at 1:1, meaning both the core and shader domain clock in at 1006 MHz, that means that the 2x shader hotclock from the last generation products is a thing of the past. This boils down to to a memory bandwidth of 192 GB/s on that 256-bit memory bus.
On the memory controller side of things you'll see very significant improvements as the reference memory clock is now set at 6 GHz / Gbps. But let me first show you GK104:Īs far as the memory specs of the GK104 Kepler GPU are concerned, the boards will feature a 256-bit memory bus connected to 2 GB of GDDR5 video buffer memory, but later versions will also be available with 4 GB of VRAM. The product is obviously PCI-Express 3.0 ready and has a TDP of around 195W with a typical draw of 170W. The 10" long GeForce GTX 680 boasts an impressive 1536 CUDA (shader) cores.
Interestingly enough it is based on the 28nm GK104 GPU which typically would have indicated a mid-range product. The GeForce GTX 680 released today is based on the new Kepler GPU architecture.
