Compare any two graphics cards:
Radeon R9 M270X vs Radeon RX 580
IntroThe Radeon R9 M270X comes with a GPU clock speed of 725 MHz, and the 2048 MB of GDDR5 memory is set to run at 1125 MHz through a 128-bit bus. It also is made up of 640 Stream Processors, 40 TAUs, and 16 Raster Operation Units.Compare that to the Radeon RX 580, which features GPU clock speed of 1257 MHz, and 8192 MB of GDDR5 memory running at 2000 MHz through a 256-bit bus. It also is comprised of 2304 Stream Processors, 144 TAUs, and 32 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the Radeon RX 580 should be 264% quicker than the Radeon R9 M270X overall, because of its greater data rate. (explain)
Texel RateThe Radeon RX 580 is a lot (more or less 524%) more effective at AF than the Radeon R9 M270X. (explain)
Pixel RateThe Radeon RX 580 is much (approximately 247%) better at AA than the Radeon R9 M270X, and also will be capable of handling higher resolutions while still performing well. (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: Bandwidth is the largest amount of information (measured in MB per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output 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 max fill rate.
