Compare any two graphics cards:
VS

GeForce GTX 650 Ti 2GB vs Radeon HD 5970

Intro

The GeForce GTX 650 Ti 2GB comes with a GPU core clock speed of 928 MHz, and the 2048 MB of GDDR5 memory runs at 1350 MHz through a 128-bit bus. It also is made up of 768 SPUs, 64 TAUs, and 16 ROPs.

Compare all that to the Radeon HD 5970, which has a clock speed of 725 MHz and a GDDR5 memory frequency of 1000 MHz. It also features a 256-bit memory bus, and uses a 40 nm design. It is made up of 1600 SPUs, 160 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 650 Ti 2GB 110 Watts
Radeon HD 5970 294 Watts
Difference: 184 Watts (167%)

Memory Bandwidth

Theoretically, the Radeon HD 5970 should be quite a bit faster than the GeForce GTX 650 Ti 2GB in general. (explain)

GeForce GTX 650 Ti 2GB 86400 MB/sec
Difference: 169600 (196%)

Texel Rate

The Radeon HD 5970 is much (about 291%) more effective at texture filtering than the GeForce GTX 650 Ti 2GB. (explain)

Radeon HD 5970 232000 Mtexels/sec
GeForce GTX 650 Ti 2GB 59392 Mtexels/sec
Difference: 172608 (291%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon HD 5970 is superior to the GeForce GTX 650 Ti 2GB, by far. (explain)

Radeon HD 5970 92800 Mpixels/sec
GeForce GTX 650 Ti 2GB 14848 Mpixels/sec
Difference: 77952 (525%)

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 max amount of information (counted in megabytes per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the bus width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at handling 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 card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
