Compare any two graphics cards:
GeForce GTX 650 vs Radeon R7 250
IntroThe GeForce GTX 650 features core speeds of 1058 MHz on the GPU, and 1250 MHz on the 1024 MB of GDDR5 RAM. It features 384 SPUs as well as 32 TAUs and 16 ROPs.
Compare all of that to the Radeon R7 250, which features a core clock speed of 1000 MHz and a GDDR5 memory frequency of 1150 MHz. It also uses a 128-bit memory bus, and makes use of a 28 nm design. It is comprised of 384 SPUs, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce GTX 650 is 9% faster than the Radeon R7 250 overall, due to its greater data rate. (explain)
Texel RateThe GeForce GTX 650 is a lot (more or less 41%) more effective at anisotropic filtering than the Radeon R7 250. (explain)
Pixel RateThe GeForce GTX 650 should be much (more or less 112%) better at full screen anti-aliasing than the Radeon R7 250, and will be capable of handling higher screen resolutions without slowing down too much. (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: Bandwidth is the maximum amount of data (in units of MB per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
