Compare any two graphics cards:
Radeon HD 7770 vs Radeon R7 260X
IntroThe Radeon HD 7770 features a GPU core clock speed of 1000 MHz, and the 1024 MB of GDDR5 memory is set to run at 1125 MHz through a 128-bit bus. It also is made up of 640 SPUs, 40 Texture Address Units, and 16 ROPs.
Compare that to the Radeon R7 260X, which has a clock speed of 1100 MHz and a GDDR5 memory speed of 1625 MHz. It also uses a 128-bit bus, and uses a 28 nm design. It is comprised of 896 SPUs, 56 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the Radeon R7 260X should theoretically be much superior to the Radeon HD 7770 in general. (explain)
Texel RateThe Radeon R7 260X should be much (about 54%) faster with regards to texture filtering than the Radeon HD 7770. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon R7 260X is the winner, but only just. (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 largest amount of information (in units of megabytes per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total texture units of the card by the core clock 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 per second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
