Radeon Pro Duo vs Radeon RX 460 2GB

Intro

Compare all that to the Radeon RX 460 2GB, which comes with a GPU core clock speed of 1090 MHz, and 2048 MB of GDDR5 RAM set to run at 1750 MHz through a 128-bit bus. It also is comprised of 896 SPUs, 56 Texture Address Units, and 16 ROPs.

Texel Rate

The Radeon Pro Duo will be much (approximately 739%) more effective at texture filtering 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

The Radeon Pro Duo will be a lot (more or less 634%) better at anti-aliasing than the Radeon RX 460 2GB, and also able to handle higher resolutions without losing too much performance. (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 maximum amount of information (in units of megabytes per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better 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 processed in one second. This number is calculated by multiplying the total number of 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of 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 number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as 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.
