GeForce 8800 Ultra vs GeForce GTX 560

Intro

Compare all of that to the GeForce GTX 560, which uses a 40 nm design. nVidia has set the core frequency at 810 MHz. The GDDR5 RAM runs at a frequency of 1001 MHz on this specific card. It features 336 SPUs along with 56 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 560		150 Watts
GeForce 8800 Ultra		171 Watts
	Difference: 21 Watts (14%)

Memory Bandwidth

Performance-wise, the GeForce GTX 560 should theoretically be a lot superior to the GeForce 8800 Ultra in general. (explain)

GeForce GTX 560		128128 MB/sec
GeForce 8800 Ultra		103680 MB/sec
	Difference: 24448 (24%)

Texel Rate

The GeForce GTX 560 should be just a bit (about 16%) more effective at texture filtering than the GeForce 8800 Ultra. (explain)

GeForce GTX 560		45360 Mtexels/sec
GeForce 8800 Ultra		39168 Mtexels/sec
	Difference: 6192 (16%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 560 is the winner, by a large margin. (explain)

GeForce GTX 560		25920 Mpixels/sec
GeForce 8800 Ultra		14688 Mpixels/sec
	Difference: 11232 (76%)

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 (measured in megabytes per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
