In terms of overall gaming performance, the graphical capabilities of the AMD FirePro V5900 are noticeably better than the Intel HD i5 6400T.

The FirePro V5900 has a 250 MHz higher core clock speed and 16 more Texture Mapping Units than the HD i5 6400T. This results in the FirePro V5900 providing 13.6 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 FirePro V5900 has a 250 MHz higher core clock speed and 24 more Render Output Units than the HD i5 6400T. This results in the FirePro V5900 providing 16.4 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 FirePro V5900, 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 FirePro V5900 when running the latest games.

The FirePro V5900 has 2048 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 FirePro V5900 has 512. However, the actual shader performance of the HD i5 6400T is 182 and the actual shader performance of the FirePro V5900 is 200. The FirePro V5900 having 18 better shader performance and an altogether better performance when taking into account other relevant data means that the FirePro V5900 delivers a massively smoother and more efficient experience when processing graphical data than the HD i5 6400T.

The HD i5 6400T transistor size technology is 26 nm (nanometers) smaller than the FirePro V5900. This means that the HD i5 6400T is expected to run slightly cooler and achieve higher clock frequencies than the FirePro V5900.

The HD i5 6400T requires 35 Watts to run and the FirePro V5900 requires 75 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 FirePro V5900. The FirePro V5900 requires 40 Watts more than the HD i5 6400T to run. The difference is significant enough that the FirePro V5900 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.

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.
FirePro C5900 is a server Graphics Card based on the 40nm Terascale 2 architecture.
It's based on the Cayman Core (related to Radeon HD 6950) and therefore offers 512 Shader Processing Units, 32 TMUs and 32 ROPs on a 256-bit interface of fast GDDR5. The central unit is clocked 600MHz while the memory clock operates at 1000MHZ.
Despite featuring a Cayman Core, its LE variant features over 100% less Shader Processing Units and thus its performance lies between Radeon HD 6670 and Radeon HD 6750.
