Geforce GTX 1080 Ti vs Radeon RX 6600 XT

Intro

Compare those specifications to the Radeon RX 6600 XT, which comes with GPU core speed of 1968 MHz, and 8192 MB of GDDR6 RAM set to run at 2000 MHz through a 128-bit bus. It also is made up of 2048 Stream Processors, 128 TAUs, and 64 ROPs.

Radeon RX 6600 XT		262144 MB/sec
	Difference: 233472 (89%)

Texel Rate

The Geforce GTX 1080 Ti will be a lot (approximately 32%) better at AF than the Radeon RX 6600 XT. (explain)

Geforce GTX 1080 Ti		331520 Mtexels/sec
Radeon RX 6600 XT		251904 Mtexels/sec
	Difference: 79616 (32%)

Pixel Rate

If running with a high resolution is important to you, then the Geforce GTX 1080 Ti is the winner, but it probably won't make a huge difference. (explain)

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of megabytes per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the bus width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
