GeForce RTX 3080 Ti vs Radeon Pro Duo

Intro

Compare that to the Radeon Pro Duo, which uses a 28 nm design. AMD has clocked the core speed at 1000 MHz. The HBM RAM is set to run at a frequency of 500 MHz on this particular model. It features 4096 SPUs along with 256 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Performance-wise, the Radeon Pro Duo should theoretically be a little bit better 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 (approximately 17%) faster with regards to 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 resolution is important to you, then the GeForce RTX 3080 Ti is a better choice, but not by far. (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 maximum amount of data (measured in MB per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, 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 amount of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
