GeForce RTX 2080 SUPER vs Radeon Pro Duo

Intro

Compare those specs to the Radeon Pro Duo, which features a clock frequency of 1000 MHz and a HBM memory speed of 500 MHz. It also uses a 4096-bit memory bus, and uses a 28 nm design. It features 4096 SPUs, 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

Theoretically speaking, the Radeon Pro Duo should perform much 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 will be a lot (approximately 62%) faster with regards to AF 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 should be quite a bit (about 21%) more effective at full screen anti-aliasing than the GeForce RTX 2080 SUPER, and also should be able to handle higher screen resolutions while still performing well. (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: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
