GeForce 8800 GS vs GeForce 8800 GT 256MB

Intro

Compare those specs to the GeForce 8800 GT 256MB, which has GPU core speed of 600 MHz, and 256 MB of GDDR3 RAM running at 700 MHz through a 256-bit bus. It also is made up of 112 SPUs, 56 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the GeForce 8800 GT 256MB should be a little bit faster than the GeForce 8800 GS in general. (explain)

GeForce 8800 GT 256MB		44800 MB/sec
GeForce 8800 GS		38400 MB/sec
	Difference: 6400 (17%)

Texel Rate

The GeForce 8800 GT 256MB should be much (approximately 27%) faster with regards to texture filtering than the GeForce 8800 GS. (explain)

GeForce 8800 GT 256MB		33600 Mtexels/sec
GeForce 8800 GS		26400 Mtexels/sec
	Difference: 7200 (27%)

Pixel Rate

The GeForce 8800 GT 256MB will be quite a bit (about 45%) faster with regards to AA than the GeForce 8800 GS, and should be able to handle higher screen resolutions better. (explain)

GeForce 8800 GT 256MB		9600 Mpixels/sec
GeForce 8800 GS		6600 Mpixels/sec
	Difference: 3000 (45%)

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.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in MB per second) that can be moved across the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
