GeForce RTX 2080 SUPER vs Radeon Pro Duo

Intro

Compare that to the Radeon Pro Duo, which comes with a GPU core clock speed of 1000 MHz, and 4096 MB of HBM memory set to run at 500 MHz through a 4096-bit bus. It also is made up of 4096 SPUs, 256 TAUs, and 64 Raster Operation Units.

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

Theoretically speaking, the Radeon Pro Duo should perform a lot faster than the GeForce RTX 2080 SUPER in general. (explain)

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

Texel Rate

The Radeon Pro Duo is much (approximately 62%) more effective 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

The Radeon Pro Duo will be quite a bit (approximately 21%) more effective at AA than the GeForce RTX 2080 SUPER, and also will be capable of handling higher screen resolutions better. (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.

Specifications

Memory Bandwidth: Bandwidth is the max amount of information (in units of MB per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
