Nvidia Titan X vs Radeon RX 6800 XT

Intro

Compare those specs to the Radeon RX 6800 XT, which has GPU core speed of 1825 MHz, and 16384 MB of GDDR6 RAM set to run at 2000 MHz through a 256-bit bus. It also features 4608 Stream Processors, 288 Texture Address Units, and 128 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Nvidia Titan X		250 Watts
Radeon RX 6800 XT		300 Watts
	Difference: 50 Watts (20%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6800 XT should be 7% quicker than the Nvidia Titan X in general, because of its greater bandwidth. (explain)

Radeon RX 6800 XT		524288 MB/sec
Nvidia Titan X		491520 MB/sec
	Difference: 32768 (7%)

Texel Rate

The Radeon RX 6800 XT will be much (approximately 66%) more effective at 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

If running with a high screen resolution is important to you, then the Radeon RX 6800 XT is a better choice, and very much so. (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: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the bus width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. 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 high 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 texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour 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 is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
