GeForce 8800 GT 256MB vs GeForce 8800 GTS (G92)

Intro

The GeForce 8800 GT 256MB features core clock speeds of 600 MHz on the GPU, and 700 MHz on the 256 MB of GDDR3 memory. It features 112 SPUs as well as 56 Texture Address Units and 16 ROPs.

Compare those specs to the GeForce 8800 GTS (G92), which makes use of a 65 nm design. nVidia has clocked the core frequency at 650 MHz. The GDDR3 RAM works at a speed of 970 MHz on this particular card. It features 128 SPUs as well as 64 TAUs and 16 ROPs.

GeForce 8800 GTS (G92) 62080 MB/sec
GeForce 8800 GT 256MB 44800 MB/sec
Difference: 17280 (39%)

Texel Rate

The GeForce 8800 GTS (G92) is quite a bit (more or less 24%) better at texture filtering than the GeForce 8800 GT 256MB. (explain)

GeForce 8800 GTS (G92) 41600 Mtexels/sec
GeForce 8800 GT 256MB 33600 Mtexels/sec
Difference: 8000 (24%)

Pixel Rate

The GeForce 8800 GTS (G92) will be a little bit (about 8%) more effective at anti-aliasing than the GeForce 8800 GT 256MB, and capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce 8800 GTS (G92) 10400 Mpixels/sec
GeForce 8800 GT 256MB 9600 Mpixels/sec
Difference: 800 (8%)

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: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 processed per second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill 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 max fill rate.
