GeForce 8800 GT 1GB vs GeForce GTX 460 SE

Intro

Compare those specs to the GeForce GTX 460 SE, which has a GPU core clock speed of 650 MHz, and 1024 MB of GDDR5 RAM set to run at 850 MHz through a 256-bit bus. It also is comprised of 288 Stream Processors, 48 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8800 GT 1GB		105 Watts
GeForce GTX 460 SE		150 Watts
	Difference: 45 Watts (43%)

Memory Bandwidth

In theory, the GeForce GTX 460 SE is 89% quicker than the GeForce 8800 GT 1GB in general, due to its higher data rate. (explain)

GeForce GTX 460 SE		108800 MB/sec
GeForce 8800 GT 1GB		57600 MB/sec
	Difference: 51200 (89%)

Texel Rate

The GeForce 8800 GT 1GB should be a bit (about 8%) better at anisotropic filtering than the GeForce GTX 460 SE. (explain)

GeForce 8800 GT 1GB		33600 Mtexels/sec
GeForce GTX 460 SE		31200 Mtexels/sec
	Difference: 2400 (8%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 460 SE is the winner, and very much so. (explain)

GeForce GTX 460 SE		20800 Mpixels/sec
GeForce 8800 GT 1GB		9600 Mpixels/sec
	Difference: 11200 (117%)

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 largest amount of data (in units of MB per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics 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 amount of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many 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.
