Radeon Pro Duo vs Radeon RX 6950 XT

Intro

Compare those specs to the Radeon RX 6950 XT, which comes with GPU clock speed of 1925 MHz, and 16384 MB of GDDR6 memory running at 2250 MHz through a 256-bit bus. It also is made up of 5120 Stream Processors, 320 TAUs, and 128 ROPs.

Radeon Pro Duo		512000 Mtexels/sec
	Difference: 104000 (20%)

Pixel Rate

The Radeon RX 6950 XT is a lot (approximately 93%) faster with regards to FSAA than the Radeon Pro Duo, and capable of handling higher resolutions without losing too much performance. (explain)

Radeon RX 6950 XT		246400 Mpixels/sec
Radeon Pro Duo		128000 Mpixels/sec
	Difference: 118400 (93%)

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 maximum amount of information (counted in megabytes per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 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 anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
