Overview
GeForce GT 545 3GB is a Fast-Middle-Class 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 GF116-400-A1 which has 3 Stream Multiprocessors activated and thus offers 144 Shader Processing Units, 24 TMUs and 16 ROPs. The Central Unit is clocked at 720MHz.

Memory
The GPU accesses a 3GB frame buffer of DDR3, through a 192-bit memory interface. The size of the frame buffer is exaggerated and in no way benefits the GPU. The Memory Clock Operates at 800MHz.

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

Cooling Solution
The Cooling Solution consists of a Single-Fan.

Power Consumption
With a rated board TDP of 70W, it requires at least a 400W PSU and it relies entirely on the PCI Slot for power, meaning no extra connectors are required.

Performance
Gaming benchmarks put its performance slightly above Radeon HD 6670 v2.

System Suggestions
We recommend a modest processor (Intel Core i3) and 8GB of RAM for a system with GeForce GT 545 3GB.
