GeForce GTX 460 SE vs Radeon HD 5570

Intro

Compare those specs to the Radeon HD 5570, which features GPU clock speed of 650 MHz, and 512 MB of DDR3 RAM running at 900 MHz through a 128-bit bus. It also is comprised of 400(80x5) Stream Processors, 20 Texture Address Units, and 8 ROPs.

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

Memory Bandwidth

In theory, the GeForce GTX 460 SE is 278% quicker than the Radeon HD 5570 in general, because of its greater 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 is quite a bit (more or less 140%) faster with regards to texture filtering 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 much (about 300%) more effective at AA than the Radeon HD 5570, and capable of handling higher resolutions without losing too much performance. (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 over the external memory interface in one second. It is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better 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 can be processed in one second. This number is calculated by multiplying the total number of texture units 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 applied in one second.

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