Nvidia Titan Xp vs Radeon RX 6800 XT

Intro

Compare that to the Radeon RX 6800 XT, which has clock speeds of 1825 MHz on the GPU, and 2000 MHz on the 16384 MB of GDDR6 RAM. It features 4608 SPUs along with 288 Texture Address Units and 128 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Performance-wise, the Nvidia Titan Xp should in theory be a small bit better than the Radeon RX 6800 XT in general. (explain)

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

Texel Rate

The Radeon RX 6800 XT is quite a bit (approximately 38%) more effective at texture filtering than the Nvidia Titan Xp. (explain)

Radeon RX 6800 XT		525600 Mtexels/sec
Nvidia Titan Xp		379680 Mtexels/sec
	Difference: 145920 (38%)

Pixel Rate

The Radeon RX 6800 XT is a lot (more or less 54%) better at anti-aliasing than the Nvidia Titan Xp, and also should be capable of handling higher resolutions without slowing down too much. (explain)

Radeon RX 6800 XT		233600 Mpixels/sec
Nvidia Titan Xp		151872 Mpixels/sec
	Difference: 81728 (54%)

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 max amount of information (measured in MB per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 are applied in one second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the clock speed of the card. 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 quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
