In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 8800 GTS 640MB are significantly better than the Nvidia GeForce GT 630 Palit 2GB Edition.

The GT 630 has a 267 MHz higher core clock speed but 8 fewer Texture Mapping Units than the 8800 GTS. The lower TMU count doesn't matter, though, as altogether the GT 630 manages to provide 0.2 GTexel/s better texturing performance. 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 267 MHz higher core clock speed than the 8800 GTS, but the 8800 GTS has 16 more Render Output Units than the GT 630. As a result, the 8800 GTS exhibits a 7.2 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 8800 GTS, 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 8800 GTS when running the latest games.

The GT 630 has 1408 MB more video memory than the 8800 GTS, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the 8800 GTS has superior memory performance.

The 8800 GTS has 46.3 GB/sec greater memory bandwidth than the GT 630, which means that the memory performance of the 8800 GTS is noticeably better than the GT 630.

Both the GeForce 8800 GTS 640MB and the GeForce GT 630 Palit 2GB Edition have 96 Shader Processing Units. While the two GPUs have the same number of SPUs, the actual performance delivered by the GT 630 is 150 and by the 8800 GTS is 150. Knowing that the shader performance of the GT 630 is superior, it is not necessary to examine the GPUs' respective Texture and Pixel Fill Rates.

The GT 630 transistor size technology is 50 nm (nanometers) smaller than the 8800 GTS. This means that the GT 630 is expected to run much cooler and achieve higher clock frequencies than the 8800 GTS.

The GeForce 8800 GTS 640MB requires 143 Watts to run and the GeForce GT 630 Palit 2GB Edition requires 65 Watts. We would recommend a PSU with at least 400 Watts for the 8800 GTS and a PSU with at least 300 Watts for the GT 630. The 8800 GTS requires 78 Watts more than the GT 630 to run. The difference is significant enough that the 8800 GTS may have an adverse affect on your yearly electricity bills in comparison to the GT 630.

GPU Mini Review

Mini ReviewGeForce 8800 GTS 640MB is a high-end GFX based on the 90nm variant of the first-shader unified architecture.
It's based on the G80 Core and offers 96 Shader Processing Units, 24 TMUs and 20 ROPs, on a 320-bit memory interface of GDDR3. The central unit runs at 513MHz and the memory clock operates 792MHz. It will consume no more than 143 Watt.
Technically, next in series, when compared to GeForce 8800 GT, it performs worse as the amount of Shader Processing Units and TMUs was reduced and the GPU comes under-clocked, in exchange for a wider bus-width and extra video memory.
Today's modern demanding games can be played at medium (most) or high settings (some) smoothly. However, DirectX 11 based games aren't supported.
GeForce GT 630 Palit 2GB Edition is a special edition of NVIDIA's Middle-Class GeForce GT 630, created by Palit.

Overclock: Central Unit
The Central Unit runs at 780MHz.

Overclock: Memory Clock
The Operating Memory Clock runs at 535MHz and the Frame Buffer was raised to 2GB. This is a gimmick and in no way benefits the GPU.

Cooling Solution
The Cooling System Remains The Same.

Due to being under-clocked, GeForce GT 630 Palit 2GB Edition is actually slower than the reference GeForce GT 630.
