In terms of overall gaming performance, the graphical capabilities of the Intel UHD Graphics 620 are significantly better than the Nvidia GeForce GT 550M 2GB.

The GT 550M has a 440 MHz higher core clock speed but 8 fewer Texture Mapping Units than the UHD Graphics 620. The lower TMU count doesn't matter, though, as altogether the GT 550M manages to provide 4.6 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 GT 550M has a 440 MHz higher core clock speed and 1 more Render Output Units than the UHD Graphics 620. This results in the GT 550M providing 2.1 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 UHD Graphics 620 was released over three years more recently than the GT 550M, and so the UHD Graphics 620 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GT 550M when running the latest games.

The GT 550M has 2048 MB video memory, but the UHD Graphics 620 does not have an entry, so the two GPUs cannot be reliably compared in this area.

The UHD Graphics 620 has 192 Shader Processing Units and the GeForce GT 550M 2GB has 96. However, the actual shader performance of the GT 550M is 142. The UHD Graphics 620 having 50 better shader performance is not particularly notable, as altogether the GT 550M performs better when taking into account other relevant data.

The UHD Graphics 620 transistor size technology is 26 nm (nanometers) smaller than the GT 550M. This means that the UHD Graphics 620 is expected to run slightly cooler and achieve higher clock frequencies than the GT 550M.

The UHD Graphics 620 requires 15 Watts to run and the GeForce GT 550M 2GB requires 35 Watts. The GT 550M requires 20 Watts more than the UHD Graphics 620 to run. The difference is not significant enough for the GT 550M to have a noticeably larger impact on your yearly electricity bills than the UHD Graphics 620.

GPU Mini Review

Mini ReviewOverview
Intel UHD Graphics 620 are integrated graphics in some of Intel's Kaby Lake mobile processors.

The Kaby Lake architecture succeeds the Skylake architecture and aims for increased CPU and graphics performance, via the same power requirements. It includes support for DirectX 12.1, OpenCL 2.1 and OpenGL 4.6.
The GPU solution, codenamed GT2, offers 192 shader processing units (SPU), 24 TMUs and 3 ROPs.

The central unit initially runs at 300MHz and goes up to 1000MHz, in turbo mode.

Memory: Speed
The operating memory clock depends at which speed the system's RAM is running and which memory type is installed and is ultimately limited by the highest operating speed that the processor supports.
Depending on whether or not the system's RAM is dual-channelled, it can access either a 64-bit or 128-bit Memory Interface.

Memory: Frame Buffer
The GPU Shares the system's RAM which varies according to the system. The GPU may reserve up to 1.7GB.

Because Performance depends heavily on the Memory Bandwidth, it may vary heavily from System to System.
Best case scenario, expect performance identical to a dedicated GeForce 525M.

System Suggestions
Intel UHD Graphics 620 is best suited for resolutions up to and including 1366x768. We recommend 4GB of RAM for optimal performance.
GeForce GT 550M 2GB is a middle-class Mobile Graphics Card based on the first revision of the Fermi Architecture.

The Fermi Architecture is manufactured with a 40nm technology and uses a technique known as Hot Clocking: The Shaders are clocked twice as fast as the Central Unit. While this leads to a reasonable performance boost, it causes enormous amounts of energy dissipation, leading, ultimately, to a significantly higher operating temperature.
Fermi is also the first GPU architecture with fully cached memory access which increases memory performance.

It equips a GPU Codenamed GF108 which has 2 Stream Multiprocessors activated and thus offers 96 Shader Processing Units, 16 TMUs and 4 ROPs. The Central Unit is clocked at 740MHz.

The GPU accesses a 2GB frame buffer of DDR3, through a 128-bit memory interface. The size of the frame buffer is exaggerated and in no way benefits the GPU. The Memory Clock Operates at 900MHz.

DirectX 11.0 Support (11.0 Hardware Default) and support for Optimus, 3D Vision Surround, PhysX, Realtime Raytracing and other technologies

Power Consumption
With a rated board TDP of 35W, it is suited for 15" or larger laptops.

Gaming benchmarks put its performance only slightly above a desktop GeForce GT 430.

System Suggestions
We recommend a modest processor (Intel Core i3 Mobile) and 4GB of RAM for a system with GeForce GT 550M 2GB.
