Compare any two graphics cards:
Radeon R9 380 2G vs Radeon R9 M390X
IntroThe Radeon R9 380 2G features a GPU clock speed of 970 MHz, and the 2048 MB of GDDR5 RAM runs at 1425 MHz through a 256-bit bus. It also is made up of 1792 Stream Processors, 112 Texture Address Units, and 32 Raster Operation Units.Compare those specifications to the Radeon R9 M390X, which comes with a GPU core clock speed of 723 MHz, and 4096 MB of GDDR5 memory set to run at 1250 MHz through a 256-bit bus. It also is made up of 2048 SPUs, 128 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon R9 380 2G is 14% faster than the Radeon R9 M390X in general, due to its higher data rate. (explain)
Texel RateThe Radeon R9 380 2G should be just a bit (approximately 17%) more effective at AF than the Radeon R9 M390X. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Radeon R9 380 2G is the winner, and very much so. (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 data (measured in MB per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total amount of texture units by the core clock 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 processed in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units 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 quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
