Radeon Pro Duo vs Radeon R9 Nano

Intro

Compare all that to the Radeon R9 Nano, which comes with GPU core speed of 1000 MHz, and 4096 MB of HBM RAM set to run at 500 MHz through a 4096-bit bus. It also is made up of 4096 SPUs, 256 Texture Address Units, and 64 Raster Operation Units.

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

Pixel Rate

The Radeon Pro Duo will be quite a bit (about 100%) faster with regards to FSAA than the Radeon R9 Nano, and also will be able to handle higher screen resolutions while still performing well. (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.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in MB per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, the result should 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 AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
