Compare any two graphics cards:
Radeon R7 250X 2GB vs Radeon R9 M280X
IntroThe Radeon R7 250X 2GB has a GPU core clock speed of 1000 MHz, and the 2048 MB of GDDR5 memory is set to run at 1125 MHz through a 128-bit bus. It also is made up of 640 Stream Processors, 40 TAUs, and 16 ROPs.Compare those specifications to the Radeon R9 M280X, which makes use of a 28 nm design. AMD has clocked the core speed at 900 MHz. The GDDR5 memory is set to run at a speed of 1375 MHz on this card. It features 896 SPUs as well as 56 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon R9 M280X should in theory be a lot better than the Radeon R7 250X 2GB in general. (explain)
Texel RateThe Radeon R9 M280X will be much (approximately 26%) faster with regards to AF than the Radeon R7 250X 2GB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon R7 250X 2GB is the winner, though not 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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the clock 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 quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
