Compare any two graphics cards:
Radeon HD 6750 1GB vs Radeon R7 250
IntroThe Radeon HD 6750 1GB comes with a GPU core speed of 725 MHz, and the 1024 MB of GDDR5 memory is set to run at 1000 MHz through a 128-bit bus. It also is made up of 720 Stream Processors, 36 Texture Address Units, and 16 Raster Operation Units.Compare those specs to the Radeon R7 250, which features clock speeds of 1000 MHz on the GPU, and 1150 MHz on the 1024 MB of GDDR5 RAM. It features 384 SPUs along with 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon R7 250 should in theory perform just a bit faster than the Radeon HD 6750 1GB overall. (explain)
Texel RateThe Radeon HD 6750 1GB will be a small bit (more or less 9%) better at AF than the Radeon R7 250. (explain)
Pixel RateThe Radeon HD 6750 1GB will be a lot (more or less 45%) better at FSAA than the Radeon R7 250, and will be capable of handling 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 max amount of data (in units of MB per second) that can be moved past the external memory interface in a second. It's worked out by multiplying the bus width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is worked out by multiplying the total amount of 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 in a second. Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
