Nvidia Titan Xp vs Radeon RX 7900 XT

Intro

Compare that to the Radeon RX 7900 XT, which has core speeds of 1500 MHz on the GPU, and 2500 MHz on the 20480 MB of GDDR6 RAM. It features 5376 SPUs as well as 336 TAUs and 192 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Nvidia Titan Xp		250 Watts
Radeon RX 7900 XT		300 Watts
	Difference: 50 Watts (20%)

Memory Bandwidth

Theoretically, the Radeon RX 7900 XT should be much faster than the Nvidia Titan Xp in general. (explain)

Radeon RX 7900 XT		819200 MB/sec
Nvidia Titan Xp		560845 MB/sec
	Difference: 258355 (46%)

Texel Rate

The Radeon RX 7900 XT is quite a bit (more or less 33%) more effective at AF than the Nvidia Titan Xp. (explain)

Radeon RX 7900 XT		504000 Mtexels/sec
Nvidia Titan Xp		379680 Mtexels/sec
	Difference: 124320 (33%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 7900 XT is a better choice, by a large margin. (explain)

Radeon RX 7900 XT		288000 Mpixels/sec
Nvidia Titan Xp		151872 Mpixels/sec
	Difference: 136128 (90%)

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 maximum amount of data (counted in MB per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 can be applied per second. This is worked out by multiplying the total texture units of the card by the core clock 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 in one second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory per 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 filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
