Nvidia Titan Xp vs Radeon RX 6800 XT

Intro

Compare those specifications to the Radeon RX 6800 XT, which features GPU clock speed of 1825 MHz, and 16384 MB of GDDR6 memory running at 2000 MHz through a 256-bit bus. It also features 4608 SPUs, 288 TAUs, and 128 Raster Operation 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

Theoretically speaking, the Nvidia Titan Xp should be 7% faster than the Radeon RX 6800 XT overall, because of its greater bandwidth. (explain)

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

Texel Rate

The Radeon RX 6800 XT should be a lot (more or less 38%) more effective at anisotropic 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 should be much (about 54%) faster with regards to anti-aliasing than the Nvidia Titan Xp, and also will 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 largest amount of information (in units of megabytes per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, it should 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 amount of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total amount of texture units of the card 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 in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
