Nvidia Titan Xp vs Radeon RX 6900 XT

Intro

Compare all of that to the Radeon RX 6900 XT, which features core speeds of 1825 MHz on the GPU, and 2000 MHz on the 16384 MB of GDDR6 RAM. It features 5120 SPUs along with 320 TAUs and 128 Rasterization Operator Units.

Power Consumption (Max TDP)

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

Memory Bandwidth

The Nvidia Titan Xp should in theory be a small bit faster than the Radeon RX 6900 XT overall. (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 quite a bit (approximately 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 running with a high resolution is important to you, then the Radeon RX 6900 XT is a better choice, by far. (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 largest amount of data (in units of MB per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

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