Radeon R9 M395X 160000 MB/sec
Difference: 352000 (220%)

Texel Rate

The Radeon R9 Nano is a lot (more or less 177%) faster with regards to anisotropic filtering than the Radeon R9 M395X. (explain)

Radeon R9 Nano 256000 Mtexels/sec
Radeon R9 M395X 92544 Mtexels/sec
Difference: 163456 (177%)

Pixel Rate

If using a high resolution is important to you, then the Radeon R9 Nano is superior to the Radeon R9 M395X, by far. (explain)

Radeon R9 Nano 64000 Mpixels/sec
Radeon R9 M395X 23136 Mpixels/sec
Difference: 40864 (177%)

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 maximum amount of information (measured in MB per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 amount of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

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