In terms of overall gaming performance, the graphical capabilities of the Intel HD i7 6700K are significantly better than the AMD Radeon HD 2900 Pro.

The HD 2900 has a 250 MHz higher core clock speed and the same number of Texture Mapping Units as the HD i7 6700K. This results in the HD 2900 providing 4 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 HD 2900 has a 250 MHz higher core clock speed and 8 more Render Output Units than the HD i7 6700K. This results in the HD 2900 providing 6.8 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 HD 2900, 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 HD 2900 when running the latest games.

The HD 2900 has 512 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 Radeon HD 2900 Pro has 320. However, the actual shader performance of the HD i7 6700K is 221 and the actual shader performance of the HD 2900 is 125. The HD i7 6700K having 96 better shader performance is not particularly notable, as altogether the HD 2900 performs better when taking into account other relevant data.

The HD i7 6700K transistor size technology is 66 nm (nanometers) smaller than the HD 2900. This means that the HD i7 6700K is expected to run massively cooler and achieve higher clock frequencies than the HD 2900.

The HD i7 6700K requires 91 Watts to run and the Radeon HD 2900 Pro requires 200 Watts. We would recommend a PSU with at least 300 Watts for the HD i7 6700K and a PSU with at least 550 Watts for the HD 2900. The HD 2900 requires 109 Watts more than the HD i7 6700K to run. The difference is significant enough that the HD 2900 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.
Radeon HD 2900 Pro is a high-end GPU based on the 80nm variant of the second unified shader architecture, R600.
It's based on the R600 Pro Core and offers 320 Shader Processing Units, 16 TMUs and 16 ROPs on a 256-bit memory interface of standard GDDR3. The central unit runs at 600MHz and the memory clock runs at up to 800MHz.
Its performance is quite superior to Radeon HD 2900 GT due to offering extra Shading Units. A GDDR4 version, paired with a 512-bit bus width and with a frame buffer of 1GB is also available should be significantly faster on high resolutions (thus better suited for today's modern games at 720p).
Today's games should run fluently at high settings using a 1024x768 resolution but beyond that, will require very reduced settings and DirectX 11 games aren't supported.
