Compare any two graphics cards:
Radeon R7 250X vs Radeon RX 580
IntroThe Radeon R7 250X has a GPU clock speed of 1000 MHz, and the 1024 MB of GDDR5 memory runs at 1125 MHz through a 128-bit bus. It also features 640 Stream Processors, 40 Texture Address Units, and 16 ROPs.Compare those specifications 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 SPUs, 144 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon RX 580 should theoretically perform much faster than the Radeon R7 250X overall. (explain)
Texel RateThe Radeon RX 580 should be quite a bit (about 353%) faster with regards to texture filtering than the Radeon R7 250X. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon RX 580 is a better choice, by far. (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 over the external memory interface in a second. The number is worked out by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total texture units by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
