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

Intro

The Radeon RX 5700 XT 50th Anniversary Edition makes use of a 7 nm design. AMD has clocked the core frequency at 1680 MHz. The GDDR6 RAM runs at a frequency of 1750 MHz on this model. It features 2560 SPUs along with 160 TAUs and 64 Rasterization Operator Units.

Compare that to the Radeon RX 6900 XT, which has a core clock speed of 1825 MHz and a GDDR6 memory frequency of 2000 MHz. It also makes use of a 256-bit bus, and uses a 7 nm design. It is made up of 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

Performance-wise, the Radeon RX 6900 XT should in theory be just a bit better 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 (more or less 117%) more effective 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 using lots of anti-aliasing is important to you, then the Radeon RX 6900 XT is a better choice, by far. (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: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better 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 number of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
