VS

Radeon Pro Duo vs Radeon RX 6750 XT

Intro

The Radeon Pro Duo has core speeds of 1000 MHz on the GPU, and 500 MHz on the 4096 MB of HBM RAM. It features 4096 SPUs as well as 256 Texture Address Units and 64 Rasterization Operator Units.

Compare all that to the Radeon RX 6750 XT, which has a clock frequency of 2150 MHz and a GDDR6 memory speed of 2250 MHz. It also makes use of a 192-bit bus, and uses a 7 nm design. It is comprised of 2560 SPUs, 160 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6750 XT 250 Watts
Radeon Pro Duo 350 Watts
Difference: 100 Watts (40%)

Memory Bandwidth

Theoretically speaking, the Radeon Pro Duo is 131% quicker than the Radeon RX 6750 XT in general, due to its greater data rate. (explain)

Radeon Pro Duo 1024000 MB/sec
Radeon RX 6750 XT 442368 MB/sec
Difference: 581632 (131%)

Texel Rate

The Radeon Pro Duo will be a lot (approximately 49%) better at texture filtering than the Radeon RX 6750 XT. (explain)

Radeon Pro Duo 512000 Mtexels/sec
Radeon RX 6750 XT 344000 Mtexels/sec
Difference: 168000 (49%)

Pixel Rate

The Radeon RX 6750 XT should be a bit (about 8%) faster with regards to full screen anti-aliasing than the Radeon Pro Duo, and also will be able to handle higher screen resolutions while still performing well. (explain)

Radeon RX 6750 XT 137600 Mpixels/sec
Radeon Pro Duo 128000 Mpixels/sec
Difference: 9600 (8%)

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.

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. 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 texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
