GeForce GTX 590 vs Radeon HD 5750 1GB

Intro

Compare that to the Radeon HD 5750 1GB, which uses a 40 nm design. AMD has clocked the core frequency at 700 MHz. The GDDR5 RAM is set to run at a speed of 1150 MHz on this specific card. It features 720(144x5) SPUs along with 36 TAUs and 16 Rasterization Operator Units.

Radeon HD 5750 1GB		86 Watts
GeForce GTX 590		365 Watts
	Difference: 279 Watts (324%)

Memory Bandwidth

In theory, the GeForce GTX 590 should be 346% quicker than the Radeon HD 5750 1GB overall, because of its higher data rate. (explain)

GeForce GTX 590		328320 MB/sec
Radeon HD 5750 1GB		73600 MB/sec
	Difference: 254720 (346%)

Texel Rate

The GeForce GTX 590 is much (more or less 208%) better at anisotropic filtering than the Radeon HD 5750 1GB. (explain)

GeForce GTX 590		77696 Mtexels/sec
Radeon HD 5750 1GB		25200 Mtexels/sec
	Difference: 52496 (208%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 590 is the winner, by far. (explain)

GeForce GTX 590		58272 Mpixels/sec
Radeon HD 5750 1GB		11200 Mpixels/sec
	Difference: 47072 (420%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
