Nvidia Titan Xp vs Radeon RX 6800

Intro

Compare all that to the Radeon RX 6800, which makes use of a 7 nm design. AMD has clocked the core frequency at 1700 MHz. The GDDR6 RAM works at a speed of 2000 MHz on this particular model. It features 3840 SPUs along with 240 Texture Address Units and 96 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the Nvidia Titan Xp should be a small bit faster than the Radeon RX 6800 overall. (explain)

Nvidia Titan Xp		560845 MB/sec
Radeon RX 6800		524288 MB/sec
	Difference: 36557 (7%)

Texel Rate

The Radeon RX 6800 is a little bit (about 7%) faster with regards to AF than the Nvidia Titan Xp. (explain)

Radeon RX 6800		408000 Mtexels/sec
Nvidia Titan Xp		379680 Mtexels/sec
	Difference: 28320 (7%)

Pixel Rate

The Radeon RX 6800 will be a small bit (more or less 7%) more effective at FSAA than the Nvidia Titan Xp, and also will be capable of handling higher resolutions without losing too much performance. (explain)

Radeon RX 6800		163200 Mpixels/sec
Nvidia Titan Xp		151872 Mpixels/sec
	Difference: 11328 (7%)

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 largest amount of information (measured in megabytes per second) that can be transported over the external memory interface in one second. The number is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type 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 AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is calculated by multiplying the total number of texture units 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 applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
