Radeon RX 5600 XT vs Radeon RX 6600

Intro

Compare all that to the Radeon RX 6600, which uses a 7 nm design. AMD has set the core speed at 1626 MHz. The GDDR6 memory works at a frequency of 1750 MHz on this specific card. It features 1792 SPUs along with 112 Texture Address Units and 64 Rasterization Operator Units.

Radeon RX 6600		229376 MB/sec
	Difference: 114688 (50%)

Texel Rate

The Radeon RX 5600 XT should be a bit (about 9%) faster with regards to AF than the Radeon RX 6600. (explain)

Radeon RX 5600 XT		198000 Mtexels/sec
Radeon RX 6600		182112 Mtexels/sec
	Difference: 15888 (9%)

Pixel Rate

The Radeon RX 6600 is just a bit (more or less 18%) better at FSAA than the Radeon RX 5600 XT, and able to handle higher screen resolutions without slowing down too much. (explain)

Radeon RX 6600		104064 Mpixels/sec
Radeon RX 5600 XT		88000 Mpixels/sec
	Difference: 16064 (18%)

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 (in units of MB per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 once again. If 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 high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
