Gaming Performance Comparison

In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 630 2GB DDR3 are noticeably better than the Nvidia GeForce 7950 GT.

The GT 630 has a 260 MHz higher core clock speed than the GeForce 7950 GT, but the GeForce 7950 GT has 8 more Texture Mapping Units than the GT 630. As a result, the GeForce 7950 GT exhibits a 0.2 GTexel/s better Texture Fill Rate than the GT 630. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GT 630 has a 260 MHz higher core clock speed than the GeForce 7950 GT, but the GeForce 7950 GT has 20 more Render Output Units than the GT 630. As a result, the GeForce 7950 GT exhibits a 10 GPixel/s better Pixel Fill Rate than the GT 630. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GT 630 was released over three years more recently than the GeForce 7950 GT, and so the GT 630 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GeForce 7950 GT when running the latest games.

The GT 630 has 1536 MB more video memory than the GeForce 7950 GT, so is likely to be much better at displaying game textures at higher resolutions. However, the overall memory performance is about the same.

The GeForce 7950 GT has 16 GB/sec greater memory bandwidth than the GT 630, which means that the memory performance of the GeForce 7950 GT is slightly better than the GT 630.

The GeForce GT 630 2GB DDR3 has 96 Shader Processing Units and the GeForce 7950 GT has 24. However, the actual shader performance of the GT 630 is 192. The GT 630 having 168 better shader performance is not particularly notable, as altogether the GeForce 7950 GT performs better when taking into account other relevant data.

The GT 630 transistor size technology is 50 nm (nanometers) smaller than the GeForce 7950 GT. This means that the GT 630 is expected to run much cooler and achieve higher clock frequencies than the GeForce 7950 GT.

The GeForce 7950 GT requires 65 Watts to run but there is no entry for the GT 630. We would recommend a PSU with at least 350 Watts for the GeForce 7950 GT, but we do not have a recommended PSU wattage for the GT 630.

GPU Mini Review

Mini ReviewGeForce GT 630 2GB DDR3 is another version of middle-class GeForce GT 630.
This version comes equipped with a 2GB frame buffer whilst the other specifications are exactly like the standard GeForce GT 630.
Therefore, GeForce GT 630 2GB DDR3 can be addressed as a gimmick: marketing to lure consumers into paying more for the same product as GeForce GT 630 2GB DDR3 is not powerful enough to use 2GB of frame buffer, due to its limited bandwidth and processing power.
The NVIDIA GeForce 7 Series graphics processing units (GPUs) represent a significant leap forward in 3D graphics design, delivering the unparalleled horsepower and revolutionary technologies you need to tackle the latest games and video applications. The GeForce 7 Series GPUs deliver blazing frame rates and outstanding image quality so you can experience full-throttle graphics performance.
