Radeon RX 5700 XT 50th Anniversary Edition vs Radeon RX 6900 XT

Intro

The Radeon RX 5700 XT 50th Anniversary Edition comes with a GPU core clock speed of 1680 MHz, and the 8096 MB of GDDR6 memory is set to run at 1750 MHz through a 256-bit bus. It also is made up of 2560 Stream Processors, 160 Texture Address Units, and 64 ROPs.

Compare all of that to the Radeon RX 6900 XT, which has a clock speed of 1825 MHz and a GDDR6 memory frequency of 2000 MHz. It also makes use of a 256-bit bus, and makes use of a 7 nm design. It features 5120 SPUs, 320 Texture Address Units, and 128 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5700 XT 50th Anniversary Edition 235 Watts
Radeon RX 6900 XT 300 Watts
Difference: 65 Watts (28%)

Memory Bandwidth

In theory, the Radeon RX 6900 XT should be a little bit faster than the Radeon RX 5700 XT 50th Anniversary Edition overall. (explain)

Radeon RX 6900 XT 524288 MB/sec
Radeon RX 5700 XT 50th Anniversary Edition 458752 MB/sec
Difference: 65536 (14%)

Texel Rate

The Radeon RX 6900 XT is a lot (about 117%) better at anisotropic filtering than the Radeon RX 5700 XT 50th Anniversary Edition. (explain)

Radeon RX 6900 XT 584000 Mtexels/sec
Radeon RX 5700 XT 50th Anniversary Edition 268800 Mtexels/sec
Difference: 315200 (117%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 6900 XT is a better choice, and very much so. (explain)

Radeon RX 6900 XT 233600 Mpixels/sec
Radeon RX 5700 XT 50th Anniversary Edition 107520 Mpixels/sec
Difference: 126080 (117%)

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.

Memory Bandwidth: Bandwidth is the max amount of data (in units of MB per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is worked out by multiplying the total amount of texture units of the card 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 per second.

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