Nvidia Titan X vs Radeon RX 6800

Intro

Compare those specifications to the Radeon RX 6800, which comes with a core clock frequency of 1700 MHz and a GDDR6 memory speed of 2000 MHz. It also features a 256-bit memory bus, and uses a 7 nm design. It is comprised of 3840 SPUs, 240 TAUs, and 96 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically speaking, the Radeon RX 6800 should perform a small 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 is a lot (more or less 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

If running with high levels of AA is important to you, then the Radeon RX 6800 is superior to the Nvidia Titan X, not by a very large margin though. (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 information (in units of megabytes per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
