GeForce 8800 GT 512MB vs GeForce GTX 660

Intro

The GeForce 8800 GT 512MB uses a 65 nm design. nVidia has clocked the core speed at 600 MHz. The GDDR3 memory works at a frequency of 900 MHz on this particular card. It features 112 SPUs as well as 56 Texture Address Units and 16 ROPs.

Compare all of that to the GeForce GTX 660, which features core clock speeds of 980 MHz on the GPU, and 1502 MHz on the 2048 MB of GDDR5 RAM. It features 960 SPUs along with 80 Texture Address Units and 24 Rasterization Operator Units.

GeForce 8800 GT 512MB 105 Watts
GeForce GTX 660 140 Watts
Difference: 35 Watts (33%)

Memory Bandwidth

In theory, the GeForce GTX 660 is 150% faster than the GeForce 8800 GT 512MB in general, because of its higher data rate. (explain)

GeForce GTX 660 144192 MB/sec
GeForce 8800 GT 512MB 57600 MB/sec
Difference: 86592 (150%)

Texel Rate

The GeForce GTX 660 should be a lot (about 133%) better at AF than the GeForce 8800 GT 512MB. (explain)

GeForce GTX 660 78400 Mtexels/sec
GeForce 8800 GT 512MB 33600 Mtexels/sec
Difference: 44800 (133%)

Pixel Rate

The GeForce GTX 660 is quite a bit (more or less 145%) more effective at FSAA than the GeForce 8800 GT 512MB, and able to handle higher resolutions while still performing well. (explain)

GeForce GTX 660 23520 Mpixels/sec
GeForce 8800 GT 512MB 9600 Mpixels/sec
Difference: 13920 (145%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the bus width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
