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 set the core speed at 2321 MHz. The GDDR6 RAM works at a frequency of 2000 MHz on this particular model. It features 2560 SPUs along with 160 TAUs and 64 ROPs.

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

Performance-wise, the Radeon Pro Duo should in theory be quite a bit superior to 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 is much (about 38%) better at AF 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 will be a small bit (approximately 16%) faster with regards to FSAA than the Radeon Pro Duo, and should be capable of handling higher screen resolutions while still performing well. (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: Memory bandwidth is the largest amount of data (counted in megabytes per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
