GeForce GTX 480 vs Radeon HD 5750 1GB

Intro

Compare all of that to the Radeon HD 5750 1GB, which makes use of a 40 nm design. AMD has set the core speed at 700 MHz. The GDDR5 RAM works at a frequency of 1150 MHz on this particular card. It features 720(144x5) SPUs as well as 36 TAUs and 16 ROPs.

Radeon HD 5750 1GB		86 Watts
GeForce GTX 480		250 Watts
	Difference: 164 Watts (191%)

Memory Bandwidth

In theory, the GeForce GTX 480 should be quite a bit faster than the Radeon HD 5750 1GB in general. (explain)

GeForce GTX 480		177408 MB/sec
Radeon HD 5750 1GB		73600 MB/sec
	Difference: 103808 (141%)

Texel Rate

The GeForce GTX 480 should be much (more or less 67%) more effective at AF than the Radeon HD 5750 1GB. (explain)

GeForce GTX 480		42000 Mtexels/sec
Radeon HD 5750 1GB		25200 Mtexels/sec
	Difference: 16800 (67%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 480 is the winner, by a large margin. (explain)

GeForce GTX 480		33600 Mpixels/sec
Radeon HD 5750 1GB		11200 Mpixels/sec
	Difference: 22400 (200%)

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 maximum amount of data (counted in MB per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

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