GeForce GTX 460 SE vs Radeon HD 5670

Intro

Compare all that to the Radeon HD 5670, which features a core clock frequency of 775 MHz and a GDDR5 memory frequency of 1000 MHz. It also uses a 128-bit bus, and makes use of a 40 nm design. It is made up of 400(80x5) SPUs, 20 TAUs, and 8 Raster Operation Units.

Radeon HD 5670		61 Watts
GeForce GTX 460 SE		150 Watts
	Difference: 89 Watts (146%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 460 SE is 70% quicker than the Radeon HD 5670 overall, due to its greater bandwidth. (explain)

GeForce GTX 460 SE		108800 MB/sec
Radeon HD 5670		64000 MB/sec
	Difference: 44800 (70%)

Texel Rate

The GeForce GTX 460 SE should be a lot (about 101%) faster with regards to texture filtering than the Radeon HD 5670. (explain)

GeForce GTX 460 SE		31200 Mtexels/sec
Radeon HD 5670		15500 Mtexels/sec
	Difference: 15700 (101%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 460 SE is superior to the Radeon HD 5670, by far. (explain)

GeForce GTX 460 SE		20800 Mpixels/sec
Radeon HD 5670		6200 Mpixels/sec
	Difference: 14600 (235%)

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 information (counted in MB per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 can be applied in one second. This is calculated 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
