GeForce RTX 3080 Ti vs Radeon Pro Duo

Intro

Compare all of that to the Radeon Pro Duo, which comes with core speeds of 1000 MHz on the GPU, and 500 MHz on the 4096 MB of HBM memory. It features 4096 SPUs along with 256 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The Radeon Pro Duo should in theory be just a bit faster than the GeForce RTX 3080 Ti overall. (explain)

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

Texel Rate

The Radeon Pro Duo is a little bit (more or less 17%) better at anisotropic 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

The GeForce RTX 3080 Ti will be just a bit (approximately 19%) faster with regards to FSAA than the Radeon Pro Duo, and should be capable of handling higher resolutions better. (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: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 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, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
