GeForce GTX 460 SE vs Radeon HD 6750

Intro

Compare all that to the Radeon HD 6750, which features a GPU core clock speed of 725 MHz, and 512 MB of GDDR5 RAM set to run at 1000 MHz through a 128-bit bus. It also is comprised of 720 Stream Processors, 36 Texture Address Units, and 16 Raster Operation Units.

Radeon HD 6750		86 Watts
GeForce GTX 460 SE		150 Watts
	Difference: 64 Watts (74%)

Memory Bandwidth

The GeForce GTX 460 SE, in theory, should perform quite a bit faster than the Radeon HD 6750 in general. (explain)

GeForce GTX 460 SE		108800 MB/sec
Radeon HD 6750		64000 MB/sec
	Difference: 44800 (70%)

Texel Rate

The GeForce GTX 460 SE should be just a bit (more or less 20%) better at AF than the Radeon HD 6750. (explain)

GeForce GTX 460 SE		31200 Mtexels/sec
Radeon HD 6750		26100 Mtexels/sec
	Difference: 5100 (20%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 460 SE is superior to the Radeon HD 6750, by a large margin. (explain)

GeForce GTX 460 SE		20800 Mpixels/sec
Radeon HD 6750		11600 Mpixels/sec
	Difference: 9200 (79%)

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 (counted in megabytes per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 amount of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
