GeForce GTX 460 SE vs Radeon HD 5570

Intro

Compare those specs to the Radeon HD 5570, which comes with GPU clock speed of 650 MHz, and 512 MB of DDR3 memory running at 900 MHz through a 128-bit bus. It also is made up of 400(80x5) Stream Processors, 20 TAUs, and 8 Raster Operation Units.

Radeon HD 5570		13000 Mtexels/sec
	Difference: 18200 (140%)

Pixel Rate

The GeForce GTX 460 SE is much (about 300%) more effective at anti-aliasing than the Radeon HD 5570, and also able to handle higher screen 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: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be moved over the external memory interface within a second. It's worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total number 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 per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
