GeForce 8800 GTS (G92) vs GeForce 8800 GTX

Intro

Compare all of that to the GeForce 8800 GTX, which features a clock speed of 575 MHz and a GDDR3 memory frequency of 900 MHz. It also makes use of a 384-bit bus, and makes use of a 90 nm design. It is made up of 128 SPUs, 64 TAUs, and 24 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8800 GTS (G92)		135 Watts
GeForce 8800 GTX		155 Watts
	Difference: 20 Watts (15%)

Memory Bandwidth

The GeForce 8800 GTX should in theory be quite a bit faster than the GeForce 8800 GTS (G92) in general. (explain)

GeForce 8800 GTX		86400 MB/sec
GeForce 8800 GTS (G92)		62080 MB/sec
	Difference: 24320 (39%)

Texel Rate

The GeForce 8800 GTS (G92) is just a bit (approximately 13%) better at anisotropic filtering than the GeForce 8800 GTX. (explain)

GeForce 8800 GTS (G92)		41600 Mtexels/sec
GeForce 8800 GTX		36800 Mtexels/sec
	Difference: 4800 (13%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce 8800 GTX is a better choice, and very much so. (explain)

GeForce 8800 GTX		13800 Mpixels/sec
GeForce 8800 GTS (G92)		10400 Mpixels/sec
	Difference: 3400 (33%)

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: Bandwidth is the largest amount of information (counted in megabytes per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total amount of texture units by the core 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 in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the card's 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 quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
