In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 620 are significantly better than the AMD Radeon HD 5450 Asus Silent 1GB Edition.

The GeForce GT 620 has a 50 MHz higher core clock speed and 8 more Texture Mapping Units than the HD 5450. This results in the GeForce GT 620 providing 6 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GeForce GT 620 has a 50 MHz higher core clock speed than the HD 5450 and the same number of Render Output Units. This results in the GeForce GT 620 providing 0.2 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GeForce GT 620 was released over a year more recently than the HD 5450, and so the GeForce GT 620 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 5450.

The Radeon HD 5450 Asus Silent 1GB Edition and the GeForce GT 620 have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GeForce GT 620 has 7.2 GB/sec greater memory bandwidth than the HD 5450, which means that the memory performance of the GeForce GT 620 is marginally better than the HD 5450.

The Radeon HD 5450 Asus Silent 1GB Edition has 80 Shader Processing Units and the GeForce GT 620 has 96. However, the actual shader performance of the HD 5450 is 52 and the actual shader performance of the GeForce GT 620 is 134. The GeForce GT 620 having 82 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GT 620 delivers a marginally smoother and more efficient experience when processing graphical data than the HD 5450.

The GeForce GT 620 requires 49 Watts to run but there is no entry for the HD 5450. We would recommend a PSU with at least 300 Watts for the GeForce GT 620, but we do not have a recommended PSU wattage for the HD 5450.

GPU Mini Review

Mini ReviewRadeon HD 5450 Asus Silent 1GB Edition is a special edition of the entry level Radeon HD 5450 that is optimized to generate less heat and noise. Compared to the standard card, it has a lower memory clock which lowers even more its already low memory bandwidth. Expect its performance to be up to 5% worse than the reference card.Overview
GeForce GT 620 is an Entry-Level Graphics Card based on the first 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 Fermi GF108-100-KB-A1 which has 2 Stream Multiprocessors activated and thus offers 96 Shader Processing Units, 16 TMUs and 4 ROPs. The Central Unit is clocked at 700MHz.

Memory
The GPU accesses a 1GB 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 500MHz.

Features
DirectX 11.0 Support (11.0 Hardware Default) and support for 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 49W, it requires at least a 300W PSU and it relies entirely on the PCI Slot for power, meaning no extra connectors are required.

Performance
Gaming benchmarks put its performance is somewhat better than Radeon HD 7470.

System Suggestions
We recommend a modest processor (Intel Celeron) and 4GB of RAM for a system with GeForce GT 620.
