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

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the Geforce GTX 780 should in theory be a lot better than the Radeon R9 270X in general. (explain)
Texel RateThe Geforce GTX 780 is a lot (more or less 107%) better at texture filtering than the Radeon R9 270X. (explain)
Pixel RateThe Geforce GTX 780 is quite a bit (more or less 29%) faster with regards to anti-aliasing than the Radeon R9 270X, and also should be able to handle higher screen resolutions more effectively. (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 (in units of megabytes per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory speed. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one 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 graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
