Obviously there's a lot more to talk through. So we talked about the core clocks, specifications and memory partitions. Let's again put most of the data in a chart to get an idea and better overview of changes: Graphics card (reference) A 4 GB version will be manufactured as well.Īs you can understand, the massive memory partitions, bus-width and combination of GDDR5 memory (quad data rate) allow the GPU to work with a very high framebuffer bandwidth (effective). Each memory partition utilizes one memory controller on the respective GPU, which will get 256/512 MB of memory tied to it. The result is this memory speeds up-to 6 Gbps. The hardware engineers of NVIDIA reworked the memory subs system quite a bit, enabling much higher memory clock frequency speeds compared to previous generation GeForce GPUs.

Memory wise NVIDIA has nice large memory volumes due to their architecture, we pass 2 GB as standard these days for most of NVIDIA's series 690 graphics cards.

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 the acual GK104 die: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 being reviewed today is based on the new Kepler GPU architecture.
