GeForce GT 620M Review

Overview
GeForce GT 620M is a entry-level Mobile Graphics Card based on the second 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 GF117 which has 2 Stream Multiprocessors activated and thus offers 96 Shader Processing Units, 16 TMUs and 8 ROPs. The Central Unit is clocked at 625MHz.
Additionally, GF117 is built using a 28nm technology.


Memory
The GPU accesses a 1GB frame buffer of DDR3, through a 64-bit memory interface. The size of the frame buffer is exaggerated and 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 15W, it is suited for small laptops.


Performance
Of all the GeForce GT 620M variants, this one is the slowest but also the one that consumes less energy and heats less, as it is built using a 28nm technology.
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.

Then you have a "rarer" version. Select GT 620M 2GB instead. It performs exactly like yours :D

Yeah. I know. There are two 620M - up to 625MHz - up to 128 bit.
No mention of Hybrid SLI..

SLI is two cards working together. In your case would be two 620M but this GPU doesn't support SLI.

Is the GT 620M just a slightly faster GT 525M…? I remember playing Modern Warfare 3 on a Dell Inspiron laptop with an i5 2410M and a GT 525M and it was running on high settings at 45 fps no problem and Crysis2 high settings and 36 fps…
