Radeon Pro Duo vs Radeon RX 470 4GB

Intro

Compare that to the Radeon RX 470 4GB, which features core speeds of 926 MHz on the GPU, and 1650 MHz on the 4096 MB of GDDR5 RAM. It features 2048 SPUs along with 128 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 470 4GB		120 Watts
Radeon Pro Duo		350 Watts
	Difference: 230 Watts (192%)

Memory Bandwidth

In theory, the Radeon Pro Duo is 385% faster than the Radeon RX 470 4GB overall, because of its greater data rate. (explain)

Radeon Pro Duo		1024000 MB/sec
Radeon RX 470 4GB		211200 MB/sec
	Difference: 812800 (385%)

Texel Rate

The Radeon Pro Duo will be much (approximately 332%) faster with regards to anisotropic filtering than the Radeon RX 470 4GB. (explain)

Radeon Pro Duo		512000 Mtexels/sec
Radeon RX 470 4GB		118528 Mtexels/sec
	Difference: 393472 (332%)

Pixel Rate

The Radeon Pro Duo should be a lot (approximately 332%) more effective at anti-aliasing than the Radeon RX 470 4GB, and should be capable of handling higher resolutions without losing too much performance. (explain)

Radeon Pro Duo		128000 Mpixels/sec
Radeon RX 470 4GB		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: Bandwidth is the max amount of data (measured in MB per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video 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 that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
