Radeon RX 550 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 clocked the core speed at 1968 MHz. The GDDR6 memory works at a speed of 2000 MHz on this model. It features 2048 SPUs as well as 128 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 550		50 Watts
Radeon RX 6600 XT		160 Watts
	Difference: 110 Watts (220%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6600 XT should be 129% quicker than the Radeon RX 550 overall, due to its greater bandwidth. (explain)

Radeon RX 6600 XT		262144 MB/sec
Radeon RX 550		114688 MB/sec
	Difference: 147456 (129%)

Texel Rate

The Radeon RX 6600 XT will be much (about 616%) more effective at texture filtering than the Radeon RX 550. (explain)

Radeon RX 6600 XT		251904 Mtexels/sec
Radeon RX 550		35200 Mtexels/sec
	Difference: 216704 (616%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 6600 XT is a better choice, and very much so. (explain)

Radeon RX 6600 XT		125952 Mpixels/sec
Radeon RX 550		17600 Mpixels/sec
	Difference: 108352 (616%)

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 megabytes per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one 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 number is calculated by multiplying the number of Raster Operations Pipelines by the the core 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 fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
