In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 8800 GTS 640MB are noticeably better than the Intel HD i7 6700K.

The 8800 GTS has a 163 MHz higher core clock speed and 8 more Texture Mapping Units than the HD i7 6700K. This results in the 8800 GTS providing 6.7 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The 8800 GTS has a 163 MHz higher core clock speed and 12 more Render Output Units than the HD i7 6700K. This results in the 8800 GTS providing 7.5 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The HD i7 6700K was released over three years more recently than the 8800 GTS, and so the HD i7 6700K is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the 8800 GTS when running the latest games.

The 8800 GTS has 640 MB video memory, but the HD i7 6700K does not have an entry, so the two GPUs cannot be reliably compared in this area.

The HD i7 6700K has 24 Shader Processing Units and the GeForce 8800 GTS 640MB has 96. However, the actual shader performance of the HD i7 6700K is 221 and the actual shader performance of the 8800 GTS is 123. The HD i7 6700K having 98 better shader performance is not particularly notable, as altogether the 8800 GTS performs better when taking into account other relevant data.

The HD i7 6700K transistor size technology is 76 nm (nanometers) smaller than the 8800 GTS. This means that the HD i7 6700K is expected to run massively cooler and achieve higher clock frequencies than the 8800 GTS.

The HD i7 6700K requires 91 Watts to run and the GeForce 8800 GTS 640MB requires 143 Watts. We would recommend a PSU with at least 300 Watts for the HD i7 6700K and a PSU with at least 400 Watts for the 8800 GTS. The 8800 GTS requires 52 Watts more than the HD i7 6700K to run. The difference is significant enough that the 8800 GTS may have an adverse affect on your yearly electricity bills in comparison to the HD i7 6700K.

GPU Mini Review

Mini ReviewOverview
Intel HD i7 6700K is the specific version of Intel HD Graphics 530 Desktop that is integrated in the Core i7-6700K Processor.

Architecture
The Skylake Core includes support for DirectX 12.1, OpenCL 2.0 and OpenGL 4.4. Additionally, it also supports DDR4 Memory.

GPU
It equips a GPU Codenamed GT2 which offers 24 Shader Processing Units, 16 TMUs and 8 ROPs. The Central Unit Initially Runs at 350MHz and goes up to 1150MHz, in Turbo Mode.

Memory
The GPU Shares the System's RAM which varies from laptop to laptop. Typically, the GPU reserves 1.7GB. Depending on whether or not the system's RAM is Dual-Channeled, it can access either a 64-bit or 128-bit memory interface. The operating memory clock also depends on the at which speed the System's RAM is running and is limited by the highest operating speed that the Processor supports. In this case, it is 1067MHz.
It is then obvious the Memory Bandwidth depends on a lot of factors and thus this Graphics Card performance may vary heavily from system to system.

Performance
Gaming benchmarks put its performance almost on level with a dedicated GeForce 920M.

System Suggestions
Intel HD i7 6700K is best suited for resolutions up to and including 1366x768. We recommend a Decent Processor and 4GB of RAM for Optimal Performance.
GeForce 8800 GTS 640MB is a high-end GFX based on the 90nm variant of the first-shader unified architecture.
It's based on the G80 Core and offers 96 Shader Processing Units, 24 TMUs and 20 ROPs, on a 320-bit memory interface of GDDR3. The central unit runs at 513MHz and the memory clock operates 792MHz. It will consume no more than 143 Watt.
Technically, next in series, when compared to GeForce 8800 GT, it performs worse as the amount of Shader Processing Units and TMUs was reduced and the GPU comes under-clocked, in exchange for a wider bus-width and extra video memory.
Today's modern demanding games can be played at medium (most) or high settings (some) smoothly. However, DirectX 11 based games aren't supported.
