Radeon Pro Duo vs Radeon RX 460 2GB

Intro

Compare all of that to the Radeon RX 460 2GB, which features a GPU core clock speed of 1090 MHz, and 2048 MB of GDDR5 memory set to run at 1750 MHz through a 128-bit bus. It also is comprised of 896 SPUs, 56 TAUs, and 16 Raster Operation Units.

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

Theoretically speaking, the Radeon Pro Duo is 814% quicker than the Radeon RX 460 2GB overall, because of its higher bandwidth. (explain)

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

Texel Rate

The Radeon Pro Duo will be a lot (about 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 lots of anti-aliasing is important to you, then the Radeon Pro Duo is the winner, and very much so. (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: Bandwidth is the largest amount of data (counted in MB per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 processed per second. This is calculated by multiplying the total texture units of the card by the core clock 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 in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of 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 rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
