Compare any two graphics cards:
Radeon HD 7750 vs Radeon R7 250
IntroThe Radeon HD 7750 makes use of a 28 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR5 RAM runs at a speed of 1125 MHz on this particular card. It features 512 SPUs as well as 32 Texture Address Units and 16 Rasterization Operator Units.
Compare that to the Radeon R7 250, which comes with GPU core speed of 1000 MHz, and 1024 MB of GDDR5 memory running at 1150 MHz through a 128-bit bus. It also is made up of 384 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the Radeon R7 250 is 2% faster than the Radeon HD 7750 overall, because of its greater bandwidth. (explain)
Texel RateThe Radeon HD 7750 is a bit (more or less 7%) better at AF than the Radeon R7 250. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon HD 7750 is the winner, by far. (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 data (counted in MB per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the graphics 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 most pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core speed of the card. 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 fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
