Compare any two graphics cards:

GeForce GTX 590 vs Radeon HD 5750 1GB

Intro

The GeForce GTX 590 makes use of a 40 nm design. nVidia has clocked the core frequency at 607 MHz. The GDDR5 memory works at a speed of 855 MHz on this particular card. It features 512 SPUs along with 64 TAUs and 48 ROPs.

Compare those specifications to the Radeon HD 5750 1GB, which features core clock speeds of 700 MHz on the GPU, and 1150 MHz on the 1024 MB of GDDR5 memory. It features 720(144x5) SPUs as well as 36 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

In theory, the GeForce GTX 590 should perform a lot faster than the Radeon HD 5750 1GB in general. (explain)

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

Texel Rate

The GeForce GTX 590 is quite a bit (more or less 208%) better at AF 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 running with a high screen resolution is important to you, then the GeForce GTX 590 is the winner, and very much so. (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.

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in MB per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
