GeForce GTX 580 vs Radeon HD 5750 1GB

Intro

Compare that to the Radeon HD 5750 1GB, which has a GPU core clock speed of 700 MHz, and 1024 MB of GDDR5 RAM running at 1150 MHz through a 128-bit bus. It also features 720(144x5) SPUs, 36 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 5750 1GB		86 Watts
GeForce GTX 580		244 Watts
	Difference: 158 Watts (184%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 580 will be 161% faster than the Radeon HD 5750 1GB in general, because of its greater bandwidth. (explain)

GeForce GTX 580		192384 MB/sec
Radeon HD 5750 1GB		73600 MB/sec
	Difference: 118784 (161%)

Texel Rate

The GeForce GTX 580 should be much (more or less 96%) more effective at AF than the Radeon HD 5750 1GB. (explain)

GeForce GTX 580		49408 Mtexels/sec
Radeon HD 5750 1GB		25200 Mtexels/sec
	Difference: 24208 (96%)

Pixel Rate

The GeForce GTX 580 will be a lot (about 231%) more effective at full screen anti-aliasing than the Radeon HD 5750 1GB, and should be able to handle higher screen resolutions better. (explain)

GeForce GTX 580		37056 Mpixels/sec
Radeon HD 5750 1GB		11200 Mpixels/sec
	Difference: 25856 (231%)

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 information (counted in MB per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

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