Compare any two graphics cards:
VS

GeForce 9600 GSO 512MB vs Radeon HD 4850 X2 1GB

Intro

The GeForce 9600 GSO 512MB features a GPU core speed of 650 MHz, and the 512 MB of GDDR3 RAM is set to run at 900 MHz through a 256-bit bus. It also features 96 SPUs, 48 Texture Address Units, and 16 Raster Operation Units.

Compare all of that to the Radeon HD 4850 X2 1GB, which comes with GPU clock speed of 625 MHz, and 1024 MB of GDDR3 RAM set to run at 993 MHz through a 256-bit bus. It also is comprised of 800(160x5) SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9600 GSO 512MB 90 Watts
Radeon HD 4850 X2 1GB 250 Watts
Difference: 160 Watts (178%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 4850 X2 1GB will be 121% faster than the GeForce 9600 GSO 512MB in general, because of its higher bandwidth. (explain)

Radeon HD 4850 X2 1GB 127104 MB/sec
GeForce 9600 GSO 512MB 57600 MB/sec
Difference: 69504 (121%)

Texel Rate

The Radeon HD 4850 X2 1GB should be much (approximately 60%) more effective at texture filtering than the GeForce 9600 GSO 512MB. (explain)

Radeon HD 4850 X2 1GB 50000 Mtexels/sec
GeForce 9600 GSO 512MB 31200 Mtexels/sec
Difference: 18800 (60%)

Pixel Rate

The Radeon HD 4850 X2 1GB is a lot (more or less 92%) better at AA than the GeForce 9600 GSO 512MB, and also will be able to handle higher screen resolutions while still performing well. (explain)

Radeon HD 4850 X2 1GB 20000 Mpixels/sec
GeForce 9600 GSO 512MB 10400 Mpixels/sec
Difference: 9600 (92%)

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 largest amount of information (in units of megabytes per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the bus width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
