GeForce 8800 GTS (G92) vs GeForce GTX 560

Intro

Compare those specifications to the GeForce GTX 560, which uses a 40 nm design. nVidia has clocked the core speed at 810 MHz. The GDDR5 RAM is set to run at a speed of 1001 MHz on this model. It features 336 SPUs as well as 56 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8800 GTS (G92)		135 Watts
GeForce GTX 560		150 Watts
	Difference: 15 Watts (11%)

Memory Bandwidth

In theory, the GeForce GTX 560 should perform quite a bit faster than the GeForce 8800 GTS (G92) in general. (explain)

GeForce GTX 560		128128 MB/sec
GeForce 8800 GTS (G92)		62080 MB/sec
	Difference: 66048 (106%)

Texel Rate

The GeForce GTX 560 should be a little bit (more or less 9%) more effective at AF than the GeForce 8800 GTS (G92). (explain)

GeForce GTX 560		45360 Mtexels/sec
GeForce 8800 GTS (G92)		41600 Mtexels/sec
	Difference: 3760 (9%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 560 is a better choice, by far. (explain)

GeForce GTX 560		25920 Mpixels/sec
GeForce 8800 GTS (G92)		10400 Mpixels/sec
	Difference: 15520 (149%)

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 max amount of data (in units of MB per second) that can be transported over the external memory interface within a second. It's worked out by multiplying the interface width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
