In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 620 are significantly better than the AMD Radeon X1650 PowerColor 256MB Edition.

The GeForce GT 620 was released over three years more recently than the X1650 PowerColor, and so the GeForce GT 620 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the X1650 PowerColor when running the latest games.

The GeForce GT 620 has 768 MB more video memory than the X1650 PowerColor, 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 X1650 PowerColor, which means that the memory performance of the GeForce GT 620 is marginally better than the X1650 PowerColor.

The Radeon X1650 PowerColor 256MB Edition has 12 Shader Processing Units and the GeForce GT 620 has 96. However, the actual shader performance of the X1650 PowerColor is 4 and the actual shader performance of the GeForce GT 620 is 134. The GeForce GT 620 having 130 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GT 620 delivers a slightly smoother and more efficient experience when processing graphical data than the X1650 PowerColor.

The GeForce GT 620 requires 49 Watts to run but there is no entry for the X1650 PowerColor. We would recommend a PSU with at least 350 Watts for the X1650 PowerColor and a PSU with at least 300 Watts for the GeForce GT 620. The X1650 PowerColor has been recommended a PSU with 50 Watts more than the GeForce GT 620. The difference is significant enough that the X1650 PowerColor may have a slight adverse affect on your yearly electricity bills in comparison to the GeForce GT 620.

GPU Mini Review

Mini ReviewRadeon X1650 PowerColor 256MB Edition is a special edition of the Radeon X1650.
This version features a 64 bits bus, instead of 128 bits and it's equipped with only 256MB. The core and memory clocks are clocked at the same speed. Therefore, the performance is inferior to the standard Radeon X1650.
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.
