Compare any two graphics cards:
GeForce GTX 780 Ti vs Radeon HD 5970
IntroThe GeForce GTX 780 Ti features core clock speeds of 875 MHz on the GPU, and 1750 MHz on the 3072 MB of GDDR5 RAM. It features 2880 SPUs along with 240 TAUs and 48 ROPs.Compare that to the Radeon HD 5970, which uses a 40 nm design. AMD has set the core frequency at 725 MHz. The GDDR5 RAM works at a frequency of 1000 MHz on this specific card. It features 1600 SPUs along with 160 TAUs and 64 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 780 Ti is 31% faster than the Radeon HD 5970 overall, due to its greater data rate. (explain)
Texel RateThe Radeon HD 5970 should be a little bit (more or less 10%) more effective at AF than the GeForce GTX 780 Ti. (explain)
Pixel RateIf using high levels of AA is important to you, then the Radeon HD 5970 is superior to the GeForce GTX 780 Ti, by a large margin. (explain)
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. Price Comparison

Memory Bandwidth: Bandwidth is the largest amount of information (measured in MB per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 again. If 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 higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
