Radeon RX 550 vs Radeon RX 6600

Intro

Compare that to the Radeon RX 6600, which uses a 7 nm design. AMD has set the core frequency at 1626 MHz. The GDDR6 RAM runs at a speed of 1750 MHz on this particular card. It features 1792 SPUs as well as 112 Texture Address Units and 64 ROPs.

Radeon RX 550		35200 Mtexels/sec
	Difference: 146912 (417%)

Pixel Rate

The Radeon RX 6600 should be quite a bit (approximately 491%) faster with regards to full screen anti-aliasing than the Radeon RX 550, and also capable of handling higher resolutions while still performing well. (explain)

Radeon RX 6600		104064 Mpixels/sec
Radeon RX 550		17600 Mpixels/sec
	Difference: 86464 (491%)

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 data (counted in MB per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The better 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 most pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
