Radeon RX 5500 XT vs Radeon RX 6600

Intro

Compare those specs to the Radeon RX 6600, which uses a 7 nm design. AMD has clocked the core speed at 1626 MHz. The GDDR6 memory is set to run at a speed of 1750 MHz on this particular card. It features 1792 SPUs as well as 112 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5500 XT		130 Watts
Radeon RX 6600		132 Watts
	Difference: 2 Watts (2%)

Memory Bandwidth

Both cards have exactly the same memory bandwidth, so in theory they should perform the same. (explain)

Texel Rate

The Radeon RX 6600 is a lot (about 21%) more effective at AF than the Radeon RX 5500 XT. (explain)

Radeon RX 6600		182112 Mtexels/sec
Radeon RX 5500 XT		151096 Mtexels/sec
	Difference: 31016 (21%)

Pixel Rate

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

Radeon RX 6600		104064 Mpixels/sec
Radeon RX 5500 XT		54944 Mpixels/sec
	Difference: 49120 (89%)

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 max amount of information (measured in megabytes per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the bus width by its memory speed. In the case of DDR 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 anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at 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 that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
