GeForce RTX 2080 SUPER vs Radeon Pro Duo

Intro

Compare those specs to the Radeon Pro Duo, which has core clock speeds of 1000 MHz on the GPU, and 500 MHz on the 4096 MB of HBM RAM. It features 4096 SPUs along with 256 TAUs and 64 ROPs.

GeForce RTX 2080 SUPER		316800 Mtexels/sec
	Difference: 195200 (62%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon Pro Duo is superior to the GeForce RTX 2080 SUPER, 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.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in MB per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the bus width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
