Radeon Pro Duo vs Radeon RX 480 4GB

Intro

Compare that to the Radeon RX 480 4GB, which comes with a core clock frequency of 1120 MHz and a GDDR5 memory frequency of 1750 MHz. It also features a 256-bit bus, and makes use of a 14 nm design. It is comprised of 2304 SPUs, 144 Texture Address Units, and 32 Raster Operation Units.

The Radeon Pro Duo should be much (about 217%) faster with regards to AF 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

The Radeon Pro Duo is quite a bit (about 257%) faster with regards to AA than the Radeon RX 480 4GB, and also will be capable of handling higher screen resolutions without losing too much performance. (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 (measured in MB per second) that can be moved past the external memory interface in one second. It is worked out by multiplying the bus width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If 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 higher screen resolutions.

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

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