In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 620 are significantly better than the AMD Radeon HD 5450 256MB.

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 GeForce GT 620 has 768 MB more video memory than the HD 5450, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GeForce GT 620 also has superior memory performance overall.

The GeForce GT 620 has 8 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 GeForce GT 620 has 96 Shader Processing Units and the Radeon HD 5450 256MB has 80. However, the actual shader performance of the GeForce GT 620 is 134 and the actual shader performance of the HD 5450 is 52. 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 and the Radeon HD 5450 256MB requires 19 Watts. We would recommend a PSU with at least 300 Watts for the GeForce GT 620 and a PSU with at least 400 Watts for the HD 5450. The GeForce GT 620 requires 30 Watts more than the HD 5450 to run. The difference is not significant enough for the GeForce GT 620 to have a noticeably larger impact on your yearly electricity bills than the HD 5450.

GPU Mini Review

Mini ReviewOverview
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.
The Evergreen series is a family of GPUs developed by AMD graphics products division. The existence was spotted on a presentation slide from AMD Technology Analyst Day July 2007 as 'R8xx'. ATI held a press event in the USS Hornet museum on September 10, 2009 and announced ATI Eyefinity multi-display technology and specifications of the Radeon HD 5800 series' variants. The first variants of the Radeon HD 5800 series were launched September 23, 2009, with the HD 5700 series launching October 12 and HD 5970 launching on November 18 The HD 5670, was launched on January 14, 2010, and the HD 5500 and 5400 series were launched in February of 2010, completing what has appeared to be most of ATI's Evergreen GPU lineup.
Demand so greatly outweighed supply that more than two months after launch, many online retailers were still having trouble keeping the 5800 and 5900 series in stock.
