Compare any two graphics cards:
Radeon HD 5750 512MB vs Radeon R7 250
IntroThe Radeon HD 5750 512MB has a GPU core clock speed of 700 MHz, and the 512 MB of GDDR5 RAM runs at 1150 MHz through a 128-bit bus. It also features 720(144x5) Stream Processors, 36 Texture Address Units, and 16 Raster Operation Units.Compare those specifications to the Radeon R7 250, which features a clock frequency of 1000 MHz and a GDDR5 memory speed of 1150 MHz. It also uses a 128-bit memory bus, and uses a 28 nm design. It features 384 SPUs, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthBoth cards have the exact same bandwidth, so in theory they should have identical performance. (explain)
Texel RateThe Radeon HD 5750 512MB should be a small bit (approximately 5%) better at AF than the Radeon R7 250. (explain)
Pixel RateThe Radeon HD 5750 512MB should be a lot (about 40%) faster with regards to full screen anti-aliasing than the Radeon R7 250, and capable of handling higher resolutions without losing too much performance. (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 max amount of information (counted in megabytes per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
