Nvidia Titan Xp vs Radeon RX 6600 XT

Intro

Compare those specifications to the Radeon RX 6600 XT, which features a core clock frequency of 1968 MHz and a GDDR6 memory frequency of 2000 MHz. It also uses a 128-bit bus, and uses a 7 nm design. It is comprised of 2048 SPUs, 128 Texture Address Units, and 64 Raster Operation Units.

Radeon RX 6600 XT		262144 MB/sec
	Difference: 298701 (114%)

Texel Rate

The Nvidia Titan Xp is a lot (more or less 51%) more effective at anisotropic filtering than the Radeon RX 6600 XT. (explain)

Nvidia Titan Xp		379680 Mtexels/sec
Radeon RX 6600 XT		251904 Mtexels/sec
	Difference: 127776 (51%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Nvidia Titan Xp is the winner, by far. (explain)

Nvidia Titan Xp		151872 Mpixels/sec
Radeon RX 6600 XT		125952 Mpixels/sec
	Difference: 25920 (21%)

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 (measured in megabytes per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
