Compare any two graphics cards:
Geforce GTX 780 vs Radeon R9 270X
IntroThe Geforce GTX 780 features core speeds of 863 MHz on the GPU, and 1502 MHz on the 3072 MB of GDDR5 RAM. It features 2304 SPUs along with 192 TAUs and 48 Rasterization Operator Units.
Compare those specs to the Radeon R9 270X, which makes use of a 28 nm design. AMD has clocked the core frequency at 1000 MHz. The GDDR5 memory works at a speed of 1400 MHz on this model. It features 1280 SPUs along with 80 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the Geforce GTX 780 should be a lot faster than the Radeon R9 270X overall. (explain)
Texel RateThe Geforce GTX 780 should be a lot (approximately 107%) more effective at AF than the Radeon R9 270X. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Geforce GTX 780 is superior to the Radeon R9 270X, and very much so. (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 max amount of information (measured in megabytes per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, the result should 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 AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
