GeForce RTX 4090 vs Radeon Pro Duo

Intro

Compare those specs to the Radeon Pro Duo, which features core speeds of 1000 MHz on the GPU, and 500 MHz on the 4096 MB of HBM RAM. It features 4096 SPUs along with 256 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon Pro Duo		350 Watts
GeForce RTX 4090		450 Watts
	Difference: 100 Watts (29%)

Memory Bandwidth

The GeForce RTX 4090 should in theory be a little bit faster than the Radeon Pro Duo overall. (explain)

GeForce RTX 4090		1042432 MB/sec
Radeon Pro Duo		1024000 MB/sec
	Difference: 18432 (2%)

Texel Rate

The GeForce RTX 4090 is a lot (more or less 124%) faster with regards to anisotropic filtering than the Radeon Pro Duo. (explain)

GeForce RTX 4090		1144320 Mtexels/sec
Radeon Pro Duo		512000 Mtexels/sec
	Difference: 632320 (124%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce RTX 4090 is the winner, by far. (explain)

GeForce RTX 4090		393360 Mpixels/sec
Radeon Pro Duo		128000 Mpixels/sec
	Difference: 265360 (207%)

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 max amount of data (counted in megabytes per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses 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 amount of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs 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 fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
