Nvidia Titan Xp vs Radeon RX 6900 XT

Intro

Compare those specs to the Radeon RX 6900 XT, which has GPU core speed of 1825 MHz, and 16384 MB of GDDR6 memory running at 2000 MHz through a 256-bit bus. It also is comprised of 5120 SPUs, 320 TAUs, and 128 ROPs.

Power Consumption (Max TDP)

Nvidia Titan Xp		250 Watts
Radeon RX 6900 XT		300 Watts
	Difference: 50 Watts (20%)

Memory Bandwidth

As far as performance goes, the Nvidia Titan Xp should in theory be a small bit superior to the Radeon RX 6900 XT in general. (explain)

Nvidia Titan Xp		560845 MB/sec
Radeon RX 6900 XT		524288 MB/sec
	Difference: 36557 (7%)

Texel Rate

The Radeon RX 6900 XT is much (about 54%) faster with regards to anisotropic filtering than the Nvidia Titan Xp. (explain)

Radeon RX 6900 XT		584000 Mtexels/sec
Nvidia Titan Xp		379680 Mtexels/sec
	Difference: 204320 (54%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 6900 XT is the winner, by a large margin. (explain)

Radeon RX 6900 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: Bandwidth is the max amount of information (counted in MB per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure 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 video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
