Compare any two graphics cards:

GeForce RTX 2080 SUPER vs Radeon Pro Duo

Intro

The GeForce RTX 2080 SUPER makes use of a 12 nm design. nVidia has set the core frequency at 1650 MHz. The GDDR6 RAM runs at a frequency of 15500 MHz on this specific model. It features 3072 SPUs as well as 192 TAUs and 64 ROPs.

Compare those specs to the Radeon Pro Duo, which has a GPU core clock speed of 1000 MHz, and 4096 MB of HBM RAM set to run at 500 MHz through a 4096-bit bus. It also is comprised of 4096 Stream Processors, 256 Texture Address Units, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2080 SUPER		250 Watts
Radeon Pro Duo		350 Watts
	Difference: 100 Watts (40%)

Memory Bandwidth

In theory, the Radeon Pro Duo should be 102% quicker than the GeForce RTX 2080 SUPER in general, because of its higher data rate. (explain)

Radeon Pro Duo		1024000 MB/sec
GeForce RTX 2080 SUPER		507904 MB/sec
	Difference: 516096 (102%)

Texel Rate

The Radeon Pro Duo is a lot (about 62%) better at texture filtering than the GeForce RTX 2080 SUPER. (explain)

Radeon Pro Duo		512000 Mtexels/sec
GeForce RTX 2080 SUPER		316800 Mtexels/sec
	Difference: 195200 (62%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon Pro Duo is the winner, by far. (explain)

Radeon Pro Duo		128000 Mpixels/sec
GeForce RTX 2080 SUPER		105600 Mpixels/sec
	Difference: 22400 (21%)

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.

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is calculated by multiplying the total 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. 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 many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
