Nvidia Titan X vs Radeon RX 6800 XT

Intro

Compare all of that to the Radeon RX 6800 XT, which features a clock frequency of 1825 MHz and a GDDR6 memory frequency of 2000 MHz. It also makes use of a 256-bit memory bus, and uses a 7 nm design. It features 4608 SPUs, 288 Texture Address Units, and 128 ROPs.

Nvidia Titan X		491520 MB/sec
	Difference: 32768 (7%)

Texel Rate

The Radeon RX 6800 XT is quite a bit (about 66%) faster with regards to anisotropic filtering than the Nvidia Titan X. (explain)

Radeon RX 6800 XT		525600 Mtexels/sec
Nvidia Titan X		317408 Mtexels/sec
	Difference: 208192 (66%)

Pixel Rate

The Radeon RX 6800 XT should be quite a bit (about 72%) more effective at anti-aliasing than the Nvidia Titan X, and also will be able to handle higher resolutions without losing too much performance. (explain)

Radeon RX 6800 XT		233600 Mpixels/sec
Nvidia Titan X		136032 Mpixels/sec
	Difference: 97568 (72%)

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: Bandwidth is the maximum amount of information (measured in megabytes per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 can be processed per second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip 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 number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
