GeForce RTX 3090 vs Radeon Pro Duo

Intro

Compare that to the Radeon Pro Duo, which has clock speeds of 1000 MHz on the GPU, and 500 MHz on the 4096 MB of HBM RAM. It features 4096 SPUs along with 256 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the Radeon Pro Duo should perform a little bit faster than the GeForce RTX 3090 in general. (explain)

Radeon Pro Duo		1024000 MB/sec
GeForce RTX 3090		958668 MB/sec
	Difference: 65332 (7%)

Texel Rate

The Radeon Pro Duo will be a bit (more or less 12%) better at texture filtering than the GeForce RTX 3090. (explain)

Radeon Pro Duo		512000 Mtexels/sec
GeForce RTX 3090		457560 Mtexels/sec
	Difference: 54440 (12%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce RTX 3090 is superior to the Radeon Pro Duo, by a large margin. (explain)

GeForce RTX 3090		156240 Mpixels/sec
Radeon Pro Duo		128000 Mpixels/sec
	Difference: 28240 (22%)

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 data (in units of MB per second) that can be moved across the external memory interface in a second. The number is worked out by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
