GeForce GTX 460 SE vs Radeon HD 5570

Intro

Compare all that to the Radeon HD 5570, which comes with core clock speeds of 650 MHz on the GPU, and 900 MHz on the 512 MB of DDR3 RAM. It features 400(80x5) SPUs along with 20 TAUs and 8 Rasterization Operator Units.

Radeon HD 5570		43 Watts
GeForce GTX 460 SE		150 Watts
	Difference: 107 Watts (249%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 460 SE should be 278% faster than the Radeon HD 5570 in general, because of its higher bandwidth. (explain)

GeForce GTX 460 SE		108800 MB/sec
Radeon HD 5570		28800 MB/sec
	Difference: 80000 (278%)

Texel Rate

The GeForce GTX 460 SE should be much (more or less 140%) faster with regards to AF than the Radeon HD 5570. (explain)

GeForce GTX 460 SE		31200 Mtexels/sec
Radeon HD 5570		13000 Mtexels/sec
	Difference: 18200 (140%)

Pixel Rate

The GeForce GTX 460 SE will be quite a bit (approximately 300%) faster with regards to FSAA than the Radeon HD 5570, and also capable of handling higher resolutions better. (explain)

GeForce GTX 460 SE		20800 Mpixels/sec
Radeon HD 5570		5200 Mpixels/sec
	Difference: 15600 (300%)

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 largest amount of data (counted in megabytes per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 once 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, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the graphics 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 could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also 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 of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
