Nvidia Titan Xp vs Radeon RX 6800

Intro

The Nvidia Titan Xp uses a 16 nm design. nVidia has clocked the core speed at 1582 MHz. The GDDR5X memory is set to run at a speed of 1426 MHz on this card. It features 3840 SPUs along with 240 TAUs and 96 ROPs.

Compare those specifications to the Radeon RX 6800, which has a clock frequency of 1700 MHz and a GDDR6 memory speed of 2000 MHz. It also uses a 256-bit memory bus, and makes use of a 7 nm design. It is comprised of 3840 SPUs, 240 TAUs, and 96 Raster Operation Units.

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 in general. (explain)

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

Texel Rate

The Radeon RX 6800 will be a bit (more or less 7%) better at texture filtering 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 should be a small bit (more or less 7%) faster with regards to FSAA than the Nvidia Titan Xp, and will be able to handle higher screen resolutions better. (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.

Memory Bandwidth: Bandwidth is the largest amount of data (counted in megabytes per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
