Compare any two graphics cards:
Radeon HD 5750 512MB vs Radeon R7 250
IntroThe Radeon HD 5750 512MB features a GPU clock speed of 700 MHz, and the 512 MB of GDDR5 memory is set to run at 1150 MHz through a 128-bit bus. It also is made up of 720(144x5) Stream Processors, 36 TAUs, and 16 Raster Operation Units.Compare those specifications to the Radeon R7 250, which features a GPU core clock 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 Stream Processors, 24 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthBoth cards have the exact same bandwidth, so in theory they should perform the same. (explain)
Texel RateThe Radeon HD 5750 512MB is a small bit (more or less 5%) more effective at AF than the Radeon R7 250. (explain)
Pixel RateThe Radeon HD 5750 512MB should be much (more or less 40%) more effective at AA than the Radeon R7 250, and should be able to handle higher 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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
