In terms of overall gaming performance, the graphical capabilities of the Intel HD i7 6700K are marginally better than the Nvidia GeForce GTS 450 v4 Asus DirectCU Silent 1GB Edition.

The GTS 450 has a 244 MHz higher core clock speed and 8 more Texture Mapping Units than the HD i7 6700K. This results in the GTS 450 providing 8.7 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 GTS 450 has a 244 MHz higher core clock speed and 8 more Render Output Units than the HD i7 6700K. This results in the GTS 450 providing 6.7 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 GTS 450, 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 GTS 450 when running the latest games.

The GTS 450 has 1024 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 GTS 450 v4 Asus DirectCU Silent 1GB Edition has 144. However, the actual shader performance of the HD i7 6700K is 221 and the actual shader performance of the GTS 450 is 171. The HD i7 6700K having 50 better shader performance and an altogether better performance when taking into account other relevant data means that the HD i7 6700K delivers a marginally smoother and more efficient experience when processing graphical data than the GTS 450.

The HD i7 6700K transistor size technology is 26 nm (nanometers) smaller than the GTS 450. This means that the HD i7 6700K is expected to run slightly cooler and achieve higher clock frequencies than the GTS 450. While they exhibit similar graphical performance, the HD i7 6700K should consume less power than the GTS 450.

The HD i7 6700K requires 91 Watts to run and the GeForce GTS 450 v4 Asus DirectCU Silent 1GB Edition requires 75 Watts. We would recommend a PSU with at least 300 Watts for the HD i7 6700K and a PSU with at least 350 Watts for the GTS 450. The HD i7 6700K requires 16 Watts more than the GTS 450 to run. The difference is not significant enough for the HD i7 6700K to have a noticeably larger impact on your yearly electricity bills than the GTS 450.

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.

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

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.

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.

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 GTS 450 v4 Asus DirectCU Silent 1GB Edition is a special edition of NVIDIA's fast-middle-class GeForce GTS 450 v4, created by Asus.

Overclock Out of The Box
The Central unit is actually underclocked reducing the power consumption and thus reducing the heat produced. Also, the Graphics Card relies entirely on the PCI Slot for power, meaning no extra connectors are required.

Cooling Solution
The Cooling System was replaced by Asus's DirectCU Silent Solution which has flattened copper heat-pipe in contact with the GPU directly for a 0dB cooling experience.

Because of being underclocked, GeForce GTS 450 v4 Asus DirectCU Silent 1GB Edition is actually slower than the reference GeForce GTS 450 v4.
