Nvidia Titan Xp vs Radeon RX 6800 XT

Intro

Compare those specs to the Radeon RX 6800 XT, which makes use of a 7 nm design. AMD has clocked the core frequency at 1825 MHz. The GDDR6 memory is set to run at a frequency of 2000 MHz on this model. It features 4608 SPUs as well as 288 Texture Address Units and 128 ROPs.

Nvidia Titan Xp		379680 Mtexels/sec
	Difference: 145920 (38%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 6800 XT is superior to the Nvidia Titan Xp, by a large margin. (explain)

Radeon RX 6800 XT		233600 Mpixels/sec
Nvidia Titan Xp		151872 Mpixels/sec
	Difference: 81728 (54%)

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 (measured in MB per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the interface width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster 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 number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total texture units by the core speed of the chip. The better this number, 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 number of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called 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 reach the maximum fill rate.
