Radeon Pro Duo vs Radeon RX 6650 XT

Intro

Compare those specs to the Radeon RX 6650 XT, which has a GPU core clock speed of 2055 MHz, and 8192 MB of GDDR6 memory set to run at 2190 MHz through a 128-bit bus. It also is comprised of 2048 SPUs, 128 TAUs, and 64 Raster Operation Units.

Texel Rate

The Radeon Pro Duo will be quite a bit (more or less 95%) more effective at anisotropic filtering than the Radeon RX 6650 XT. (explain)

Radeon Pro Duo		512000 Mtexels/sec
Radeon RX 6650 XT		263040 Mtexels/sec
	Difference: 248960 (95%)

Pixel Rate

The Radeon RX 6650 XT will be a little bit (more or less 3%) faster with regards to anti-aliasing than the Radeon Pro Duo, and will be capable of handling higher resolutions more effectively. (explain)

Radeon RX 6650 XT		131520 Mpixels/sec
Radeon Pro Duo		128000 Mpixels/sec
	Difference: 3520 (3%)

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 information (in units of megabytes per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the interface width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at handling 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 the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on 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.
