GeForce 8800 GTS (G92) vs GeForce GTX 560

Intro

Compare that to the GeForce GTX 560, which has a clock frequency of 810 MHz and a GDDR5 memory speed of 1001 MHz. It also makes use of a 256-bit bus, and makes use of a 40 nm design. It is made up of 336 SPUs, 56 Texture Address Units, and 32 ROPs.

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 is 106% faster than the GeForce 8800 GTS (G92) in general, because of its greater data rate. (explain)

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

Texel Rate

The GeForce GTX 560 will be just a bit (about 9%) better 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

The GeForce GTX 560 should be a lot (more or less 149%) more effective at full screen anti-aliasing than the GeForce 8800 GTS (G92), and also will be able to handle higher screen resolutions without slowing down too much. (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 maximum amount of data (counted in megabytes per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

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