GeForce GT 545 1.5GB Game Requirement Analysis
GeForce GT 545 1.5GB is a Fast-Middle-Class 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 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.
The GPU accesses a 1.5GB frame buffer of DDR3, through a 192-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 800MHz.
DirectX 11.0 Support (11.0 Hardware Default) and support for SLI, 3D Vision Surround, PhysX, Realtime Raytracing and other technologies
The Cooling Solution consists of a Single-Fan.
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.
Gaming benchmarks put its performance slightly above Radeon HD 6670 v2.
We recommend a modest processor (Intel Core i3) and 8GB of RAM for a system with GeForce GT 545 1.5GB.
