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

The GeForce GT 620 was released over three years more recently than the Radeon X1650 SE, 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 Radeon X1650 SE when running the latest games.

The GeForce GT 620 has 512 MB more video memory than the Radeon X1650 SE, so is likely to be much better at displaying game textures at higher resolutions. However, the overall memory performance is about the same.

The Radeon X1650 SE has 11.2 GB/sec greater memory bandwidth than the GeForce GT 620, which means that the memory performance of the Radeon X1650 SE is slightly better than the GeForce GT 620.

The GeForce GT 620 has 96 Shader Processing Units and the Radeon X1650 SE has 12. However, the actual shader performance of the GeForce GT 620 is 134 and the actual shader performance of the Radeon X1650 SE is 4. 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 marginally smoother and more efficient experience when processing graphical data than the Radeon X1650 SE.

The GeForce GT 620 requires 49 Watts to run and the Radeon X1650 SE requires 42 Watts. We would recommend a PSU with at least 300 Watts for the GeForce GT 620 and a PSU with at least 350 Watts for the Radeon X1650 SE. The GeForce GT 620 requires 7 Watts more than the Radeon X1650 SE 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 X1650 SE.

GPU Mini Review

Mini ReviewOverview
GeForce GT 620 is an Entry-Level Graphics Card based on the first 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 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.

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.

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.

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.
ATI's 'R520' core (codenamed Fudo) is the foundation for a line of DirectX 9.0c and OpenGL 2.0 3D accelerator X1000 video cards. It is ATI's first major architectural overhaul since the 'R300' core and is highly optimized for Shader Model 3.0. The Radeon X1000 series using the core was introduced on October 5, 2005, and competed primarily against nVidia's GeForce 7000 series. ATI released the successor to the R500 series with the R600 series on May 14, 2007. ATI does not provide official support for any X1000 series cards for Windows 7
