Radeon Pro Duo vs Radeon RX 470

Intro

Compare that to the Radeon RX 470, which uses a 14 nm design. AMD has clocked the core speed at 926 MHz. The GDDR5 RAM works at a speed of 1650 MHz on this card. It features 2048 SPUs along with 128 TAUs and 32 Rasterization Operator Units.

Radeon RX 470		211200 MB/sec
	Difference: 812800 (385%)

Texel Rate

The Radeon Pro Duo will be quite a bit (approximately 332%) more effective at anisotropic filtering than the Radeon RX 470. (explain)

Radeon Pro Duo		512000 Mtexels/sec
Radeon RX 470		118528 Mtexels/sec
	Difference: 393472 (332%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon Pro Duo is the winner, by far. (explain)

Radeon Pro Duo		128000 Mpixels/sec
Radeon RX 470		29632 Mpixels/sec
	Difference: 98368 (332%)

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 (counted in megabytes per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core 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 fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
