Gaming Performance Comparison

In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 8800 GT are significantly better than the Nvidia GeForce GT 630 2GB DDR3.

The GT 630 has a 210 MHz higher core clock speed than the GeForce 8800 GT, but the GeForce 8800 GT has 40 more Texture Mapping Units than the GT 630. As a result, the GeForce 8800 GT exhibits a 20.6 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 210 MHz higher core clock speed than the GeForce 8800 GT, but the GeForce 8800 GT has 12 more Render Output Units than the GT 630. As a result, the GeForce 8800 GT exhibits a 6.4 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 8800 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 8800 GT when running the latest games.

The GT 630 has 1536 MB more video memory than the GeForce 8800 GT, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the GeForce 8800 GT has superior memory performance.

The GeForce 8800 GT has 28.8 GB/sec greater memory bandwidth than the GT 630, which means that the memory performance of the GeForce 8800 GT is slightly better than the GT 630.

The GeForce GT 630 2GB DDR3 has 96 Shader Processing Units and the GeForce 8800 GT has 112. However, the actual shader performance of the GT 630 is 192. The GT 630 having 80 better shader performance is not particularly notable, as altogether the GeForce 8800 GT performs better when taking into account other relevant data.

The GT 630 transistor size technology is 25 nm (nanometers) smaller than the GeForce 8800 GT. This means that the GT 630 is expected to run slightly cooler and achieve higher clock frequencies than the GeForce 8800 GT.

The GeForce 8800 GT requires 105 Watts to run but there is no entry for the GT 630. We would recommend a PSU with at least 450 Watts for the GeForce 8800 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.
GeForce 8800 GT is a high-end GFX based on the 65nm variant of the first-shader unified architecture.
It's based on the G92 Core and offers 112 Shader Processing Units, 56 TMUs and 16 ROPs, on a 256-bit memory interface of GDDR3. The central unit runs at 600MHz and the memory clock operates 900MHz. It will consume no more than 105 Watt.
GeForce 8800 GT was added later to the GeForce 8000 Series and was manufactured with an upgraded G8X Core known as G92 (later used on the GeForce 9000 Series). It's manufactured with a smaller technology (65nm VS 90nm) and therefore heats less and consumes less power. GeForce 8800 GTS 512 also falls in the same situation but performs better thanks to the extra shading units. However, it also heats more and consumes more power.
Today's modern demanding games can be played at medium (most) or high settings (some) smoothly. However, DirectX 11 based games aren't supported and its performance will decrease substantially, as the resolution increases.
