Compare any two graphics cards:
Radeon HD 6750 1GB vs Radeon R7 250
IntroThe Radeon HD 6750 1GB has a core clock frequency of 725 MHz and a GDDR5 memory frequency of 1000 MHz. It also makes use of a 128-bit memory bus, and uses a 40 nm design. It is made up of 720 SPUs, 36 TAUs, and 16 Raster Operation Units.Compare those specs to the Radeon R7 250, which features a GPU core clock speed of 1000 MHz, and 1024 MB of GDDR5 RAM set to run 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 BandwidthAs far as performance goes, the Radeon R7 250 should theoretically be a bit better than the Radeon HD 6750 1GB overall. (explain)
Texel RateThe Radeon HD 6750 1GB should be a small bit (about 9%) more effective at texture filtering than the Radeon R7 250. (explain)
Pixel RateThe Radeon HD 6750 1GB should be a lot (more or less 45%) more effective at anti-aliasing than the Radeon R7 250, and capable of handling higher screen 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 megabytes per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the graphics 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 maximum amount of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
