In terms of overall gaming performance, the graphical capabilities of the Intel HD i5 6600T are very slightly better than the Intel HD i5 6400T.

The HD i5 6400T and the HD i5 6600T have both the same core clock speed and the same Texture Fill Rate. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The HD i5 6400T and the HD i5 6600T have both the same core clock speed and the same Pixel Fill Rate. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

Both the HD i5 6400T and the HD i5 6600T were released at the same time, so are likely to be quite similar.

The HD i5 6400T and the HD i5 6600T have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The memory bandwidth of the HD i5 6400T and the HD i5 6600T are the same, which means the HD i5 6400T and the HD i5 6600T have equal limitations when it comes to graphical data transfer.

Both the HD i5 6400T and the HD i5 6600T have 24 Shader Processing Units. Having the same number of SPUs and using the same architecture means that the performance they offer can be compared by looking at the memory bandwidth, Texture and Pixel Rates. In this case, the two GPUs have extremely similar stats, so any gaming performance difference would most likely be negligible.

The HD i5 6400T requires 35 Watts to run and the HD i5 6600T requires 65 Watts. We would recommend a PSU with at least 300 Watts for the HD i5 6400T and a PSU with at least 300 Watts for the HD i5 6600T. The HD i5 6600T requires 30 Watts more than the HD i5 6400T to run. The difference is not significant enough for the HD i5 6600T to have a noticeably larger impact on your yearly electricity bills than 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.
