Compare any two graphics cards:
Radeon HD 5750 512MB vs Radeon R7 250X 2GB
IntroThe Radeon HD 5750 512MB comes with a core clock speed of 700 MHz and a GDDR5 memory speed of 1150 MHz. It also uses a 128-bit bus, and makes use of a 40 nm design. It is made up of 720(144x5) SPUs, 36 Texture Address Units, and 16 ROPs.Compare that to the Radeon R7 250X 2GB, which comes with a core clock frequency of 1000 MHz and a GDDR5 memory frequency of 1125 MHz. It also uses a 128-bit bus, and makes use of a 28 nm design. It features 640 SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 5750 512MB should theoretically perform a small bit faster than the Radeon R7 250X 2GB overall. (explain)
Texel RateThe Radeon R7 250X 2GB will be a lot (more or less 59%) more effective at texture filtering than the Radeon HD 5750 512MB. (explain)
Pixel RateThe Radeon R7 250X 2GB will be quite a bit (approximately 43%) more effective at anti-aliasing than the Radeon HD 5750 512MB, and should be able to handle higher screen resolutions better. (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 largest amount of data (counted in MB per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better 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 number of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
