In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 9600 GSO EVGA Dual-Slot 768MB Edition are significantly better than the Nvidia GeForce GT 620.

The GeForce GT 620 has a 150 MHz higher core clock speed than the 9600 GSO, but the 9600 GSO has 32 more Texture Mapping Units than the GeForce GT 620. As a result, the 9600 GSO exhibits a 15.2 GTexel/s better Texture Fill Rate than the GeForce GT 620. 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 150 MHz higher core clock speed than the 9600 GSO, but the 9600 GSO has 8 more Render Output Units than the GeForce GT 620. As a result, the 9600 GSO exhibits a 3.8 GPixel/s better Pixel Fill Rate than the GeForce GT 620. 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 three years more recently than the 9600 GSO, 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 9600 GSO when running the latest games.

The GeForce GT 620 has 256 MB more video memory than the 9600 GSO, so is likely to be slightly better at displaying game textures at higher resolutions. However, the overall memory performance is about the same.

The 9600 GSO has 24 GB/sec greater memory bandwidth than the GeForce GT 620, which means that the memory performance of the 9600 GSO is slightly better than the GeForce GT 620.

Both the GeForce 9600 GSO EVGA Dual-Slot 768MB Edition and the GeForce GT 620 have 96 Shader Processing Units. While the two GPUs have the same number of SPUs, the actual performance delivered by the GeForce GT 620 is 134 and by the 9600 GSO is 134. Knowing that the shader performance of the GeForce GT 620 is superior, it is not necessary to examine the GPUs' respective Texture and Pixel Fill Rates.

The GeForce GT 620 transistor size technology is 25 nm (nanometers) smaller than the 9600 GSO. This means that the GeForce GT 620 is expected to run slightly cooler and achieve higher clock frequencies than the 9600 GSO.

The GeForce 9600 GSO EVGA Dual-Slot 768MB Edition requires 84 Watts to run and the GeForce GT 620 requires 49 Watts. We would recommend a PSU with at least 400 Watts for the 9600 GSO and a PSU with at least 300 Watts for the GeForce GT 620. The 9600 GSO requires 35 Watts more than the GeForce GT 620 to run. The difference is significant enough that the 9600 GSO may have a slight adverse affect on your yearly electricity bills in comparison to the GeForce GT 620.

GPU Mini Review

Mini ReviewGeForce 9600 GSO EVGA Dual-Slot 768MB Edition is a special edition of the middle-class GeForce 9600 GSO.
It offers twice as much video memory which will only offer a performance boost on superior resolutions which the card isn't very suited for from the begining. Nevertheless, expect an overall 7% performance boost over the reference 384MB card.
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.
