In terms of overall gaming performance, the graphical capabilities of the Intel HD i5 6400T are significantly better than the Nvidia GeForce 7900 GTX.

The HD i5 6400T was released over three years more recently than the GeForce 7900 GTX, and so the HD i5 6400T is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GeForce 7900 GTX when running the latest games.

The GeForce 7900 GTX has 512 MB video memory, but the HD i5 6400T does not have an entry, so the two GPUs cannot be reliably compared in this area.

Both the HD i5 6400T and the GeForce 7900 GTX have 24 Shader Processing Units. While the two GPUs have the same number of SPUs, the actual performance delivered by the HD i5 6400T is 182 and by the GeForce 7900 GTX is 16. Knowing that the shader performance of the HD i5 6400T is superior, it is not necessary to examine the GPUs' respective Texture and Pixel Fill Rates.

The HD i5 6400T requires 35 Watts to run and the GeForce 7900 GTX requires 84 Watts. We would recommend a PSU with at least 300 Watts for the HD i5 6400T and a PSU with at least 400 Watts for the GeForce 7900 GTX. The GeForce 7900 GTX requires 49 Watts more than the HD i5 6400T to run. The difference is significant enough that the GeForce 7900 GTX may have a slight adverse affect on your yearly electricity bills in comparison to the HD i5 6400T.

GPU Mini Review

Mini ReviewOverview
Intel HD i5 6400T is the specific version of Intel HD Graphics 530 Desktop that is integrated in the Core i5-6400T 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-R0 which offers 24 Shader Processing Units, 16 TMUs and 8 ROPs. The Central Unit Initially Runs at 350MHz and goes up to 950MHz, 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 i5 6400T is best suited for resolutions up to and including 1366x768. We recommend a Decent Processor and 4GB of RAM for Optimal Performance.
The NVIDIA GeForce 7 Series graphics processing units (GPUs) represent a significant leap forward in 3D graphics design, delivering the unparalleled horsepower and revolutionary technologies you need to tackle the latest games and video applications. The GeForce 7 Series GPUs deliver blazing frame rates and outstanding image quality so you can experience full-throttle graphics performance.
