Radeon R9 M390X 160000 MB/sec
Radeon R7 M360 16000 MB/sec
Difference: 144000 (900%)

Texel Rate

The Radeon R9 M390X should be much (more or less 243%) more effective at AF than the Radeon R7 M360. (explain)

Radeon R9 M390X 92544 Mtexels/sec
Radeon R7 M360 27000 Mtexels/sec
Difference: 65544 (243%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 M390X is superior to the Radeon R7 M360, by a large margin. (explain)

Radeon R9 M390X 23136 Mpixels/sec
Radeon R7 M360 9000 Mpixels/sec
Difference: 14136 (157%)

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.

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in MB per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
