In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 8800 GS are marginally better than the Intel HD i5 6400T.

The GeForce 8800 GS has a 200 MHz higher core clock speed and 32 more Texture Mapping Units than the HD i5 6400T. This results in the GeForce 8800 GS providing 20.8 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 GeForce 8800 GS has a 200 MHz higher core clock speed and 4 more Render Output Units than the HD i5 6400T. This results in the GeForce 8800 GS providing 3.8 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 i5 6400T was released over three years more recently than the GeForce 8800 GS, 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 8800 GS when running the latest games.

The GeForce 8800 GS has 384 MB video memory, but the HD i5 6400T does not have an entry, so the two GPUs cannot be reliably compared in this area.

The HD i5 6400T has 24 Shader Processing Units and the GeForce 8800 GS has 96. However, the actual shader performance of the HD i5 6400T is 182 and the actual shader performance of the GeForce 8800 GS is 132. The HD i5 6400T having 50 better shader performance is not particularly notable, as altogether the GeForce 8800 GS performs better when taking into account other relevant data.

The HD i5 6400T transistor size technology is 51 nm (nanometers) smaller than the GeForce 8800 GS. This means that the HD i5 6400T is expected to run massively cooler and achieve higher clock frequencies than the GeForce 8800 GS. While they exhibit similar graphical performance, the HD i5 6400T should consume less power than the GeForce 8800 GS.

The HD i5 6400T requires 35 Watts to run and the GeForce 8800 GS requires 105 Watts. We would recommend a PSU with at least 300 Watts for the HD i5 6400T and a PSU with at least 450 Watts for the GeForce 8800 GS. The GeForce 8800 GS requires 70 Watts more than the HD i5 6400T to run. The difference is significant enough that the GeForce 8800 GS may have an 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.

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-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.

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 i5 6400T is best suited for resolutions up to and including 1366x768. We recommend a Decent Processor and 4GB of RAM for Optimal Performance.
GeForce 8800 GS is a high-end GFX based on the 65nm variant of the first-shader unified architecture.
It's based on the G92 Core and offers 96 Shader Processing Units, 48 TMUs and 12 ROPs, on a 192-bit memory interface of GDDR3. The central unit runs at 550MHz and the memory clock operates 800MHz. It will consume no more than 105 Watt.
GeForce 8800 GS was added later to the GeForce 8000 Series and was manufactured with an upgraded G8X Core known as G92 (later used on the GeForce 9000 Series). It's manufactured with a smaller technology (65nm VS 90nm) and therefore heats less and consumes less power. Compared to GeForce 8800 GT, it performs significantly worse - especially at higher resolutions.
Today's modern demanding games can be played at medium (most) or high settings (some) smoothly. However, DirectX 11 based games aren't supported and its performance will decrease substantially, as the resolution increases.
