GeForce RTX 3090 vs Radeon Pro Duo

Intro

Compare all that to the Radeon Pro Duo, which uses a 28 nm design. AMD has set the core speed at 1000 MHz. The HBM memory is set to run at a frequency of 500 MHz on this particular card. It features 4096 SPUs as well as 256 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the Radeon Pro Duo should be 7% quicker than the GeForce RTX 3090 in general, due to its greater bandwidth. (explain)

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

Texel Rate

The Radeon Pro Duo will be just a bit (about 12%) faster with regards to AF 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 a high resolution is important to you, then the GeForce RTX 3090 is superior to the Radeon Pro Duo, by far. (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: Bandwidth is the max amount of information (in units of megabytes per second) that can be moved over 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 it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also 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 of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
