Compare any two graphics cards:
Geforce GTX 780 vs Radeon R9 270X
IntroThe Geforce GTX 780 features a GPU clock speed of 863 MHz, and the 3072 MB of GDDR5 memory runs at 1502 MHz through a 384-bit bus. It also features 2304 Stream Processors, 192 TAUs, and 48 Raster Operation Units.
Compare those specs to the Radeon R9 270X, which comes with a core clock speed of 1000 MHz and a GDDR5 memory speed of 1400 MHz. It also uses a 256-bit memory bus, and makes use of a 28 nm design. It features 1280 SPUs, 80 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Geforce GTX 780 should theoretically be a lot faster than the Radeon R9 270X overall. (explain)
Texel RateThe Geforce GTX 780 should be much (more or less 107%) faster with regards to AF than the Radeon R9 270X. (explain)
Pixel RateThe Geforce GTX 780 will be a lot (approximately 29%) more effective at full screen anti-aliasing than the Radeon R9 270X, and able to handle higher screen resolutions without losing too much performance. (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.

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be moved over the external memory interface in a second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 applied per second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the 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 the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
