In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 550M 2GB are very slightly better than the Nvidia GeForce GT 620M v2.

The GT 550M has a 80 MHz higher core clock speed and the same number of Texture Mapping Units as the GT 620M. This results in the GT 550M providing 1.2 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 GT 550M has a 80 MHz higher core clock speed than the GT 620M and the same number of Render Output Units. This results in the GT 550M providing 0.4 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 GT 620M was released over a year more recently than the GT 550M, and so the GT 620M is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GT 550M.

The GT 550M has 1024 MB more video memory than the GT 620M, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GT 550M also has superior memory performance overall.

The memory bandwidth of the GeForce GT 620M v2 and the GeForce GT 550M 2GB are the same, which means the GT 620M and the GT 550M have equal limitations when it comes to graphical data transfer.

Both the GeForce GT 620M v2 and the GeForce GT 550M 2GB have 96 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 GT 550M has 1.2 GTexel/s better Texture Fill Rate and 0.4 GPixel/s better Pixel Fill Rate, but the has GB/sec greater memory bandwidth. Although the GPUs are very similar in performance, the GT 550M takes the edge.

The GeForce GT 620M v2 requires 25 Watts to run and the GeForce GT 550M 2GB requires 35 Watts. The GT 550M requires 10 Watts more than the GT 620M 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 GT 620M.

GPU Mini Review

Mini ReviewOverview
GeForce GT 620M v2 is a entry-level Mobile Graphics Card based on the first revision of the Fermi Architecture.

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.

GPU
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 660MHz.

Memory
The GPU accesses a 1GB frame buffer of DDR3, through a 128-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 900MHz.

Features
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 15W, it is suited for small laptops.

Performance
Of all the GeForce GT 620M variants, this one is the fastest but also the one that consumes more energy and heats more, as it is has the highest clock frequencies.
Gaming benchmarks indicate its performance is on average with the older GeForce GT 540M. Gaming benchmarks indicate its performance is slightly below the older GeForce GT 525M.

System Suggestions
We recommend a modest processor (Intel Core i3 Mobile) and 4GB of RAM for a system with GeForce GT 620M v2.
Overview

While this leads to a reasonable performance boost, it causes enormous amounts of energy dissipation, leading, ultimately, to a significantly higher operating temperature.

GPU
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.

Memory
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.

Features
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.

Performance
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.
