Compare any two graphics cards:
Radeon R9 380 4G vs Radeon R9 M390X
IntroThe Radeon R9 380 4G features a GPU core speed of 970 MHz, and the 4096 MB of GDDR5 memory is set to run at 1425 MHz through a 256-bit bus. It also is comprised of 1792 Stream Processors, 112 TAUs, and 32 ROPs.Compare those specs to the Radeon R9 M390X, which comes with GPU clock speed of 723 MHz, and 4096 MB of GDDR5 RAM set to run at 1250 MHz through a 256-bit bus. It also features 2048 SPUs, 128 TAUs, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon R9 380 4G should in theory be just a bit better than the Radeon R9 M390X overall. (explain)
Texel RateThe Radeon R9 380 4G will be a little bit (approximately 17%) better at anisotropic filtering than the Radeon R9 M390X. (explain)
Pixel RateThe Radeon R9 380 4G should be much (about 34%) better at full screen anti-aliasing than the Radeon R9 M390X, and also should be capable of handling higher screen resolutions without slowing down too much. (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 information (counted in megabytes per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the bus width by its memory speed. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the 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 number of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel 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 ability to reach the maximum fill rate.
