Radeon Pro Duo vs Radeon RX 6700 XT

Intro

Compare all that to the Radeon RX 6700 XT, which makes use of a 7 nm design. AMD has clocked the core speed at 2321 MHz. The GDDR6 memory is set to run at a speed of 2000 MHz on this specific model. It features 2560 SPUs along with 160 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6700 XT		230 Watts
Radeon Pro Duo		350 Watts
	Difference: 120 Watts (52%)

Memory Bandwidth

Theoretically, the Radeon Pro Duo should perform much faster than the Radeon RX 6700 XT in general. (explain)

Radeon Pro Duo		1024000 MB/sec
Radeon RX 6700 XT		393216 MB/sec
	Difference: 630784 (160%)

Texel Rate

The Radeon Pro Duo should be a lot (more or less 38%) faster with regards to anisotropic filtering than the Radeon RX 6700 XT. (explain)

Radeon Pro Duo		512000 Mtexels/sec
Radeon RX 6700 XT		371360 Mtexels/sec
	Difference: 140640 (38%)

Pixel Rate

The Radeon RX 6700 XT is just a bit (about 16%) more effective at anti-aliasing than the Radeon Pro Duo, and able to handle higher screen resolutions better. (explain)

Radeon RX 6700 XT		148544 Mpixels/sec
Radeon Pro Duo		128000 Mpixels/sec
	Difference: 20544 (16%)

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 data (counted in MB per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the 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 number of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher 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 maximum number of pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the clock 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 many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
