In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 660 MSI Hawk 2GB Edition are massively better than the Intel HD i5 6600T.

The GTX 660 has a 735 MHz higher core clock speed and 64 more Texture Mapping Units than the HD i5 6600T. This results in the GTX 660 providing 81.2 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 GTX 660 has a 735 MHz higher core clock speed and 16 more Render Output Units than the HD i5 6600T. This results in the GTX 660 providing 23.2 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 6600T was released over a year more recently than the GTX 660, and so the HD i5 6600T is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GTX 660.

The GTX 660 has 2048 MB video memory, but the HD i5 6600T does not have an entry, so the two GPUs cannot be reliably compared in this area.

The HD i5 6600T has 24 Shader Processing Units and the GeForce GTX 660 MSI Hawk 2GB Edition has 960. However, the actual shader performance of the HD i5 6600T is 211 and the actual shader performance of the GTX 660 is 1104. The GTX 660 having 893 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 660 delivers a massively smoother and more efficient experience when processing graphical data than the HD i5 6600T.

The HD i5 6600T transistor size technology is 14 nm (nanometers) smaller than the GTX 660. This means that the HD i5 6600T is expected to run slightly cooler and achieve higher clock frequencies than the GTX 660.

The HD i5 6600T requires 65 Watts to run but there is no entry for the GeForce GTX 660 MSI Hawk 2GB Edition. We would recommend a PSU with at least 300 Watts for the HD i5 6600T.

GPU Mini Review

Mini ReviewOverview
Intel HD i5 6600T is the specific version of Intel HD Graphics 530 Desktop that is integrated in the Core i5-6600 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 1100MHz, 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 6600T is best suited for resolutions up to and including 1366x768. We recommend a Decent Processor and 4GB of RAM for Optimal Performance.
GeForce GTX 660 MSI Hawk 2GB Edition a special edition of GeForce GTX 660.
The new features include the Twin Frozr III Thermal Design cooling solution which, according to MSI, generates 20% more airflow than traditional fan design.
In terms of overclocking, the base-clock was increased from 980MHz to 1085MHz and the boost clock can now reach 1150MHz, instead of 1033MHz. The memory clock was left untouched.
The overclocking is therefore extreme and the performance boost is around 8% when compared to the standard GeForce GTX 660.
