GeForce GT 520M Review
GeForce GT 520M is a entry-level Mobile Graphics Card based on the second 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 GF119 which has 1 Stream Multiprocessors activated and thus offers 48 Shader Processing Units, 8 TMUs and 4 ROPs. The Central Unit is clocked at 740MHz.
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 800MHz.
DirectX 11.0 Support (11.0 Hardware Default) and support for Optimus, 3D Vision Surround, PhysX, Realtime Raytracing and other technologies
With a rated board TDP of 12W, it is suited for very small laptops.
Gaming benchmarks put its performance somewhat below a desktop GeForce GT 420.
We recommend a modest processor (Intel Core i3 Mobile) and 4GB of RAM for a system with GeForce GT 520M.
