GeForce GTX 560 vs Radeon HD 5750 1GB

Intro

Compare all that to the Radeon HD 5750 1GB, which has a clock speed of 700 MHz and a GDDR5 memory frequency of 1150 MHz. It also features a 128-bit memory bus, and makes use of a 40 nm design. It features 720(144x5) SPUs, 36 Texture Address Units, and 16 ROPs.

Memory Bandwidth

The GeForce GTX 560, in theory, should perform quite a bit faster than the Radeon HD 5750 1GB in general. (explain)

GeForce GTX 560		128128 MB/sec
Radeon HD 5750 1GB		73600 MB/sec
	Difference: 54528 (74%)

Texel Rate

The GeForce GTX 560 will be a lot (more or less 80%) better at anisotropic filtering than the Radeon HD 5750 1GB. (explain)

GeForce GTX 560		45360 Mtexels/sec
Radeon HD 5750 1GB		25200 Mtexels/sec
	Difference: 20160 (80%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 560 is the winner, and very much so. (explain)

GeForce GTX 560		25920 Mpixels/sec
Radeon HD 5750 1GB		11200 Mpixels/sec
	Difference: 14720 (131%)

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 (counted in megabytes per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster 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 in one second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines 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 output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
