Compare any two graphics cards:
Radeon R9 390X 8G vs Radeon R9 M380
IntroThe Radeon R9 390X 8G uses a 28 nm design. AMD has clocked the core speed at 1050 MHz. The GDDR5 RAM is set to run at a frequency of 1500 MHz on this card. It features 2816 SPUs as well as 176 Texture Address Units and 64 ROPs.Compare those specifications to the Radeon R9 M380, which features core speeds of 1000 MHz on the GPU, and 1500 MHz on the 4096 MB of GDDR5 RAM. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the Radeon R9 390X 8G will be 300% quicker than the Radeon R9 M380 in general, due to its higher data rate. (explain)
Texel RateThe Radeon R9 390X 8G should be quite a bit (about 362%) faster with regards to AF than the Radeon R9 M380. (explain)
Pixel RateThe Radeon R9 390X 8G is quite a bit (more or less 320%) more effective at FSAA than the Radeon R9 M380, and will be able to handle 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 data (in units of MB per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total number of texture units of the card by the core clock 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 processed in one second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. 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 is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
