Nvidia Titan Xp vs Radeon RX 6600 XT

Intro

The Nvidia Titan Xp features a GPU core speed of 1582 MHz, and the 12288 MB of GDDR5X RAM runs at 1426 MHz through a 384-bit bus. It also is made up of 3840 SPUs, 240 Texture Address Units, and 96 Raster Operation Units.

Compare those specifications to the Radeon RX 6600 XT, which features a GPU core clock speed of 1968 MHz, and 8192 MB of GDDR6 memory running at 2000 MHz through a 128-bit bus. It also is made up 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 should be much (more or less 51%) more effective at AF 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 a high screen resolution is important to you, then the Nvidia Titan Xp is the winner, and very much so. (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.

Memory Bandwidth: Bandwidth is the maximum amount of data (measured in megabytes per second) that can be transferred over the external memory interface in a second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 number of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total texture units by the core clock 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 in one second.

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