Compare any two graphics cards:
VS

Radeon Pro Duo vs Radeon R9 Nano

Intro

The Radeon Pro Duo comes with clock speeds of 1000 MHz on the GPU, and 500 MHz on the 4096 MB of HBM memory. It features 4096 SPUs as well as 256 TAUs and 64 Rasterization Operator Units.

Compare all of that to the Radeon R9 Nano, which has core clock speeds of 1000 MHz on the GPU, and 500 MHz on the 4096 MB of HBM memory. It features 4096 SPUs along with 256 Texture Address Units and 64 Rasterization Operator Units.

Radeon R9 Nano 512000 MB/sec
Difference: 512000 (100%)

Texel Rate

The Radeon Pro Duo should be a lot (about 100%) faster with regards to anisotropic filtering than the Radeon R9 Nano. (explain)

Radeon Pro Duo 512000 Mtexels/sec
Radeon R9 Nano 256000 Mtexels/sec
Difference: 256000 (100%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon Pro Duo is a better choice, and very much so. (explain)

Radeon Pro Duo 128000 Mpixels/sec
Radeon R9 Nano 64000 Mpixels/sec
Difference: 64000 (100%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of MB per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the 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 texture map elements (texels) that are applied per second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
