GeForce 8800 Ultra vs GeForce GTX 460 (OEM)

Intro

Compare that to the GeForce GTX 460 (OEM), which has core clock speeds of 650 MHz on the GPU, and 850 MHz on the 1024 MB of GDDR5 RAM. It features 336 SPUs along with 56 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 460 (OEM)		150 Watts
GeForce 8800 Ultra		171 Watts
	Difference: 21 Watts (14%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 460 (OEM) is 5% faster than the GeForce 8800 Ultra in general, because of its higher bandwidth. (explain)

GeForce GTX 460 (OEM)		108800 MB/sec
GeForce 8800 Ultra		103680 MB/sec
	Difference: 5120 (5%)

Texel Rate

The GeForce 8800 Ultra is just a bit (about 8%) more effective at anisotropic filtering than the GeForce GTX 460 (OEM). (explain)

GeForce 8800 Ultra		39168 Mtexels/sec
GeForce GTX 460 (OEM)		36400 Mtexels/sec
	Difference: 2768 (8%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 460 (OEM) is superior to the GeForce 8800 Ultra, and very much so. (explain)

GeForce GTX 460 (OEM)		20800 Mpixels/sec
GeForce 8800 Ultra		14688 Mpixels/sec
	Difference: 6112 (42%)

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 maximum amount of data (in units of MB per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics 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 most pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 potential to get to the max fill rate.
