GeForce GT 420 is an OEM only entry-level 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 GF108-200-A1 which has 1 Stream Multiprocessors activated and thus offers 48 Shader Processing Units, 4 TMUs and 4 ROPs. The Central Unit is clocked at 700MHz.
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 3D Vision Surround, PhysX, Realtime Raytracing and other technologies.
The Cooling Solution consists of a Single-Fan.
With a rated board TDP of 50W, it requires at least a 300W PSU and it relies entirely on the PCI Slot for power, meaning no extra connectors are required.
Gaming benchmarks put its performance around of a Radeon HD 5450.
We recommend a modest processor (Intel Celeron) and 4GB of RAM for a system with GeForce GT 430.
de_dank-est card ever :P
420 blaze it
