GeForce RTX 3080 Ti vs Radeon RX 6600

Intro

Compare all of that to the Radeon RX 6600, which features a GPU core clock speed of 1626 MHz, and 8192 MB of GDDR6 memory set to run at 1750 MHz through a 128-bit bus. It also is comprised of 1792 SPUs, 112 Texture Address Units, and 64 Raster Operation Units.

	Difference: 254688 (140%)

Pixel Rate

The GeForce RTX 3080 Ti should be much (more or less 47%) better at full screen anti-aliasing than the Radeon RX 6600, and also able to handle higher resolutions without slowing down too much. (explain)

GeForce RTX 3080 Ti		152880 Mpixels/sec
Radeon RX 6600		104064 Mpixels/sec
	Difference: 48816 (47%)

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 max amount of data (in units of MB per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total texture units of the card 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
