GeForce RTX 3080 Ti vs Radeon Pro Duo

Intro

Compare all that to the Radeon Pro Duo, which features GPU core speed of 1000 MHz, and 4096 MB of HBM RAM running at 500 MHz through a 4096-bit bus. It also features 4096 SPUs, 256 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically speaking, the Radeon Pro Duo should perform a little bit faster than the GeForce RTX 3080 Ti in general. (explain)

Radeon Pro Duo		1024000 MB/sec
GeForce RTX 3080 Ti		934297 MB/sec
	Difference: 89703 (10%)

Texel Rate

The Radeon Pro Duo is just a bit (more or less 17%) better at texture filtering than the GeForce RTX 3080 Ti. (explain)

Radeon Pro Duo		512000 Mtexels/sec
GeForce RTX 3080 Ti		436800 Mtexels/sec
	Difference: 75200 (17%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce RTX 3080 Ti is superior to the Radeon Pro Duo, but it probably won't make a huge difference. (explain)

GeForce RTX 3080 Ti		152880 Mpixels/sec
Radeon Pro Duo		128000 Mpixels/sec
	Difference: 24880 (19%)

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 data (measured in MB per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total number of 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 in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out 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 outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
