In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 620 are significantly better than the AMD Radeon R5 220.

The GeForce GT 620 has a 50 MHz higher core clock speed and 8 more Texture Mapping Units than the Radeon R5 220. 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 Radeon R5 220 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 Radeon R5 220 was released over a year more recently than the GeForce GT 620, and so the Radeon R5 220 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GeForce GT 620.

The Radeon R5 220 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 5.9 GB/sec greater memory bandwidth than the Radeon R5 220, which means that the memory performance of the GeForce GT 620 is marginally better than the Radeon R5 220.

The Radeon R5 220 has 80 Shader Processing Units and the GeForce GT 620 has 96. However, the actual shader performance of the Radeon R5 220 is 26 and the actual shader performance of the GeForce GT 620 is 134. The GeForce GT 620 having 108 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 Radeon R5 220.

The Radeon R5 220 requires 19 Watts to run and the GeForce GT 620 requires 49 Watts. We would recommend a PSU with at least 250 Watts for the Radeon R5 220 and a PSU with at least 300 Watts for the GeForce GT 620. The GeForce GT 620 requires 30 Watts more than the Radeon R5 220 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 Radeon R5 220.

GPU Mini Review

Mini ReviewOverview
Radeon R5 220 is an OEM only, entry-level Graphics Card based on the first revision of the Terascale Architecture.

Architecture
Terascale was AMD's first Unified Shader Architecture. In addition to being manufactured with a 40nm Technology, against the 55nm of previous Graphics Cards, it supports DirectX 10 and the Shaders now called Shader Processing Units have been redesigned and do all the Graphical work of Pixel and Vertex Shaders.

GPU
It equips a GPU codenamed Cedar PRO which has 1 Compute Units activated and thus offers 80 Shader Processing Units, 8 TMUs and 4 ROPs. The Central Unit Operates at 650MHz.

Memory
The GPU accesses a 1GB frame buffer of GDDR3, through a 64-bit memory interface. The memory clock operates at 800MHz. The size of the frame buffer is exaggerated and in no way benefits the GPU.

Features
DirectX 11.0 Support (11.0 Hardware Default) and support for Eyefinity, Stream Acceleration, PowerPlay and other technologies.

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

Power Consumption
With a rated board TDP of 18W, it requires at least a 250W PSU and it relies entirely on the PCI Slot for power, meaning no extra connectors are required.

Performance
Radeon R5 220 is a direct re-brand of Radeon HD 5450.
Gaming benchmarks indicate its performance is extremely limited and even the older GeForce GT 220 is still faster.

System Suggestions
We recommend a modest processor (Intel Celeron) and 2GB of RAM for a system with Radeon R5 220.
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.
