In terms of overall gaming performance, the graphical capabilities of the Intel HD i5 6400T are significantly better than the AMD Radeon X1900 XT.

The HD i5 6400T was released over three years more recently than the Radeon X1900 XT, 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 Radeon X1900 XT when running the latest games.

The Radeon X1900 XT has 256 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 Radeon X1900 XT has 48. However, the actual shader performance of the HD i5 6400T is 182 and the actual shader performance of the Radeon X1900 XT is 20. The HD i5 6400T having 162 better shader performance and an altogether better performance when taking into account other relevant data means that the HD i5 6400T delivers a marginally smoother and more efficient experience when processing graphical data than the Radeon X1900 XT.

The HD i5 6400T requires 35 Watts to run and the Radeon X1900 XT requires 100 Watts. We would recommend a PSU with at least 300 Watts for the HD i5 6400T. The Radeon X1900 XT requires 65 Watts more than the HD i5 6400T to run. The difference is significant enough that the Radeon X1900 XT 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.

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.
Radeon X1900 XT is a high-end GPU based on the 90nm variant of the R500 architecture.
It's based on the R580 Core and offers 48 Pixel Shaders, 16 TMUs and 16 ROPs, on a 256-bit of standard GDDR3. The central unit runs at 625MHz and the memory clock operates at up to 725MHz.
Its much faster than Radeon X1900 GT due to the core configuration.
Most of today's games might be playable at medium settings although the low preset will have to suffice on some. As it's not based on a Shader-Unified architecture, both DirectX 10 & 11 games aren't supported.
