Radeon RX 5600 XT vs Radeon RX 6600 XT

Intro

Compare those specs to the Radeon RX 6600 XT, which makes use of a 7 nm design. AMD has set the core frequency at 1968 MHz. The GDDR6 memory runs at a speed of 2000 MHz on this particular model. It features 2048 SPUs as well as 128 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The Radeon RX 5600 XT, in theory, should perform much faster than the Radeon RX 6600 XT overall. (explain)

Radeon RX 5600 XT		344064 MB/sec
Radeon RX 6600 XT		262144 MB/sec
	Difference: 81920 (31%)

Texel Rate

The Radeon RX 6600 XT is much (approximately 27%) more effective at AF than the Radeon RX 5600 XT. (explain)

Radeon RX 6600 XT		251904 Mtexels/sec
Radeon RX 5600 XT		198000 Mtexels/sec
	Difference: 53904 (27%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 6600 XT is superior to the Radeon RX 5600 XT, and very much so. (explain)

Radeon RX 6600 XT		125952 Mpixels/sec
Radeon RX 5600 XT		88000 Mpixels/sec
	Difference: 37952 (43%)

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: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be transferred across the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines 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 output rate also depends 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 max fill rate.
