In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 660 Zotac AMP Edition are massively better than the Nvidia GeForce 8800 GS.

The GTX 660 has a 496 MHz higher core clock speed and 32 more Texture Mapping Units than the GeForce 8800 GS. This results in the GTX 660 providing 57.3 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 GTX 660 has a 496 MHz higher core clock speed and 12 more Render Output Units than the GeForce 8800 GS. This results in the GTX 660 providing 18.5 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GTX 660 was released over three years more recently than the GeForce 8800 GS, and so the GTX 660 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GeForce 8800 GS when running the latest games.

The GTX 660 has 1664 MB more video memory than the GeForce 8800 GS, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GTX 660 also has superior memory performance overall.

The GTX 660 has 120.2 GB/sec greater memory bandwidth than the GeForce 8800 GS, which means that the memory performance of the GTX 660 is massively better than the GeForce 8800 GS.

The GeForce GTX 660 Zotac AMP Edition has 960 Shader Processing Units and the GeForce 8800 GS has 96. However, the actual shader performance of the GTX 660 is 1067 and the actual shader performance of the GeForce 8800 GS is 132. The GTX 660 having 935 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 660 delivers a massively smoother and more efficient experience when processing graphical data than the GeForce 8800 GS.

The GTX 660 transistor size technology is 37 nm (nanometers) smaller than the GeForce 8800 GS. This means that the GTX 660 is expected to run much cooler and achieve higher clock frequencies than the GeForce 8800 GS.

The GeForce 8800 GS requires 105 Watts to run but there is no entry for the GTX 660. We would recommend a PSU with at least 450 Watts for the GeForce 8800 GS, but we do not have a recommended PSU wattage for the GTX 660.

GPU Mini Review

Mini ReviewGeForce GTX 660 Zotac AMP Edition a special edition of GeForce GTX 660.
The new features include a new cooling system and in terms of overclocking, the base-clock was increased from 980MHz to 1046MHz and the boost clock can now reach 1111MHz, instead of 1033MHz. The memory clock was raised to 1652MHz.
Benchmarks indicate a 5.5% performance when compared to the reference card.
GeForce 8800 GS 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 96 Shader Processing Units, 48 TMUs and 12 ROPs, on a 192-bit memory interface of GDDR3. The central unit runs at 550MHz and the memory clock operates 800MHz. It will consume no more than 105 Watt.
GeForce 8800 GS 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. Compared to GeForce 8800 GT, it performs significantly worse - especially at higher resolutions.
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.
