Radeon Pro Duo vs Radeon RX 460 2GB

Intro

Compare those specifications to the Radeon RX 460 2GB, which comes with a clock frequency of 1090 MHz and a GDDR5 memory speed of 1750 MHz. It also uses a 128-bit bus, and makes use of a 14 nm design. It is comprised of 896 SPUs, 56 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 460 2GB		75 Watts
Radeon Pro Duo		350 Watts
	Difference: 275 Watts (367%)

Memory Bandwidth

The Radeon Pro Duo, in theory, should perform quite a bit faster than the Radeon RX 460 2GB in general. (explain)

Radeon Pro Duo		1024000 MB/sec
Radeon RX 460 2GB		112000 MB/sec
	Difference: 912000 (814%)

Texel Rate

The Radeon Pro Duo should be much (approximately 739%) more effective at AF than the Radeon RX 460 2GB. (explain)

Radeon Pro Duo		512000 Mtexels/sec
Radeon RX 460 2GB		61040 Mtexels/sec
	Difference: 450960 (739%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon Pro Duo is a better choice, by far. (explain)

Radeon Pro Duo		128000 Mpixels/sec
Radeon RX 460 2GB		17440 Mpixels/sec
	Difference: 110560 (634%)

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 max amount of data (counted in megabytes per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour 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 output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
