Radeon Pro Duo vs Radeon RX 480 4GB

Intro

Compare those specifications to the Radeon RX 480 4GB, which comes with GPU core speed of 1120 MHz, and 4096 MB of GDDR5 memory set to run at 1750 MHz through a 256-bit bus. It also features 2304 Stream Processors, 144 TAUs, and 32 Raster Operation Units.

Radeon RX 480 4GB		229376 MB/sec
	Difference: 794624 (346%)

Texel Rate

The Radeon Pro Duo is quite a bit (approximately 217%) faster with regards to anisotropic filtering than the Radeon RX 480 4GB. (explain)

Radeon Pro Duo		512000 Mtexels/sec
Radeon RX 480 4GB		161280 Mtexels/sec
	Difference: 350720 (217%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon Pro Duo is a better choice, by far. (explain)

Radeon Pro Duo		128000 Mpixels/sec
Radeon RX 480 4GB		35840 Mpixels/sec
	Difference: 92160 (257%)

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: Bandwidth is the max amount of information (counted in MB per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the interface width by the speed of its memory. In the case of DDR type memory, 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 high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
