Nvidia Titan Xp vs Radeon RX 6900 XT

Intro

Compare those specifications to the Radeon RX 6900 XT, which has a clock frequency of 1825 MHz and a GDDR6 memory frequency of 2000 MHz. It also uses a 256-bit bus, and uses a 7 nm design. It is made up of 5120 SPUs, 320 Texture Address Units, and 128 Raster Operation Units.

Radeon RX 6900 XT		524288 MB/sec
	Difference: 36557 (7%)

Texel Rate

The Radeon RX 6900 XT will be quite a bit (about 54%) better at AF than the Nvidia Titan Xp. (explain)

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

Pixel Rate

The Radeon RX 6900 XT will be a lot (about 54%) more effective at full screen anti-aliasing than the Nvidia Titan Xp, and also will be capable of handling higher screen resolutions without losing too much performance. (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: Memory bandwidth is the largest amount of information (in units of MB per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the bus width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video 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 maximum number of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
