Radeon Pro Duo vs Radeon RX 6950 XT

Intro

Compare that to the Radeon RX 6950 XT, which makes use of a 7 nm design. AMD has clocked the core frequency at 1925 MHz. The GDDR6 RAM runs at a frequency of 2250 MHz on this model. It features 5120 SPUs as well as 320 TAUs and 128 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6950 XT		335 Watts
Radeon Pro Duo		350 Watts
	Difference: 15 Watts (4%)

Memory Bandwidth

The Radeon Pro Duo, in theory, should be much faster than the Radeon RX 6950 XT in general. (explain)

Radeon Pro Duo		1024000 MB/sec
Radeon RX 6950 XT		589824 MB/sec
	Difference: 434176 (74%)

Texel Rate

The Radeon RX 6950 XT is a bit (about 20%) faster with regards to texture filtering than the Radeon Pro Duo. (explain)

Radeon RX 6950 XT		616000 Mtexels/sec
Radeon Pro Duo		512000 Mtexels/sec
	Difference: 104000 (20%)

Pixel Rate

The Radeon RX 6950 XT should be quite a bit (approximately 93%) better at anti-aliasing than the Radeon Pro Duo, and should be capable of handling higher resolutions while still performing well. (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 largest amount of data (in units of megabytes per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 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 anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total texture units of the card by the core 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 applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
