GeForce 8800 GT 1GB vs GeForce 8800 GTS (G92)

Intro

Compare all of that to the GeForce 8800 GTS (G92), which makes use of a 65 nm design. nVidia has clocked the core speed at 650 MHz. The GDDR3 memory is set to run at a frequency of 970 MHz on this model. It features 128 SPUs as well as 64 TAUs and 16 ROPs.

GeForce 8800 GT 1GB		57600 MB/sec
	Difference: 4480 (8%)

Texel Rate

The GeForce 8800 GTS (G92) should be much (more or less 24%) faster with regards to anisotropic filtering than the GeForce 8800 GT 1GB. (explain)

GeForce 8800 GTS (G92)		41600 Mtexels/sec
GeForce 8800 GT 1GB		33600 Mtexels/sec
	Difference: 8000 (24%)

Pixel Rate

The GeForce 8800 GTS (G92) will be a small bit (approximately 8%) more effective at anti-aliasing than the GeForce 8800 GT 1GB, and able to handle higher resolutions without losing too much performance. (explain)

GeForce 8800 GTS (G92)		10400 Mpixels/sec
GeForce 8800 GT 1GB		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.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of MB per second) that can be moved across the external memory interface in one second. It's worked out by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
