Nvidia Titan X vs Radeon RX 6800

Intro

Compare those specifications to the Radeon RX 6800, which makes use of a 7 nm design. AMD has clocked the core speed at 1700 MHz. The GDDR6 RAM is set to run at a speed of 2000 MHz on this specific model. It features 3840 SPUs along with 240 Texture Address Units and 96 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The Radeon RX 6800, in theory, should be a little bit faster than the Nvidia Titan X overall. (explain)

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

Texel Rate

The Radeon RX 6800 should be much (approximately 29%) faster with regards to AF than the Nvidia Titan X. (explain)

Radeon RX 6800		408000 Mtexels/sec
Nvidia Titan X		317408 Mtexels/sec
	Difference: 90592 (29%)

Pixel Rate

The Radeon RX 6800 will be just a bit (more or less 20%) better at AA than the Nvidia Titan X, and also capable of handling higher resolutions more effectively. (explain)

Radeon RX 6800		163200 Mpixels/sec
Nvidia Titan X		136032 Mpixels/sec
	Difference: 27168 (20%)

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 within a second. It is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better 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 can be applied per second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, 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 maximum number of pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
