Radeon RX 5700 XT 50th Anniversary Edition vs Radeon RX 6600 XT

Intro

Compare those specs to the Radeon RX 6600 XT, which has GPU core speed of 1968 MHz, and 8192 MB of GDDR6 memory set to run at 2000 MHz through a 128-bit bus. It also features 2048 SPUs, 128 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6600 XT		160 Watts
Radeon RX 5700 XT 50th Anniversary Edition		235 Watts
	Difference: 75 Watts (47%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 5700 XT 50th Anniversary Edition is 75% faster than the Radeon RX 6600 XT in general, because of its greater data rate. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		458752 MB/sec
Radeon RX 6600 XT		262144 MB/sec
	Difference: 196608 (75%)

Texel Rate

The Radeon RX 5700 XT 50th Anniversary Edition should be just a bit (more or less 7%) more effective at anisotropic filtering than the Radeon RX 6600 XT. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		268800 Mtexels/sec
Radeon RX 6600 XT		251904 Mtexels/sec
	Difference: 16896 (7%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 6600 XT is a better choice, but it probably won't make a huge difference. (explain)

Radeon RX 6600 XT		125952 Mpixels/sec
Radeon RX 5700 XT 50th Anniversary Edition		107520 Mpixels/sec
	Difference: 18432 (17%)

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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (counted in MB per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the video 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 record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
