GeForce RTX 2080 vs Radeon Pro Duo

Intro

The GeForce RTX 2080 makes use of a 12 nm design. nVidia has clocked the core speed at 1515 MHz. The GDDR6 RAM is set to run at a frequency of 14 MHz on this card. It features 2944 SPUs as well as 184 Texture Address Units and 64 Rasterization Operator Units.

Compare that to the Radeon Pro Duo, which makes use of a 28 nm design. AMD has set the core speed at 1000 MHz. The HBM memory works at a frequency of 500 MHz on this particular card. It features 4096 SPUs along with 256 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2080 215 Watts
Radeon Pro Duo 350 Watts
Difference: 135 Watts (63%)

Memory Bandwidth

The Radeon Pro Duo should theoretically be quite a bit faster than the GeForce RTX 2080 overall. (explain)

Radeon Pro Duo 1024000 MB/sec
GeForce RTX 2080 458752 MB/sec
Difference: 565248 (123%)

Texel Rate

The Radeon Pro Duo is much (about 84%) more effective at texture filtering than the GeForce RTX 2080. (explain)

Radeon Pro Duo 512000 Mtexels/sec
GeForce RTX 2080 278760 Mtexels/sec
Difference: 233240 (84%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon Pro Duo is the winner, and very much so. (explain)

Radeon Pro Duo 128000 Mpixels/sec
GeForce RTX 2080 96960 Mpixels/sec
Difference: 31040 (32%)

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.

Memory Bandwidth: Bandwidth is the largest amount of data (counted 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 its memory speed. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 are processed in one second. This is calculated by multiplying the total texture units 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
