Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Nvidia Titan Xp		250 Watts
Radeon RX 7900 XTX		355 Watts
	Difference: 105 Watts (42%)

Memory Bandwidth

In theory, the Radeon RX 7900 XTX should be 75% quicker than the Nvidia Titan Xp in general, because of its greater data rate. (explain)

Radeon RX 7900 XTX		983040 MB/sec
Nvidia Titan Xp		560845 MB/sec
	Difference: 422195 (75%)

Texel Rate

The Radeon RX 7900 XTX is much (more or less 88%) better at texture filtering than the Nvidia Titan Xp. (explain)

Radeon RX 7900 XTX		712320 Mtexels/sec
Nvidia Titan Xp		379680 Mtexels/sec
	Difference: 332640 (88%)

Pixel Rate

The Radeon RX 7900 XTX will be quite a bit (more or less 135%) faster with regards to FSAA than the Nvidia Titan Xp, and should be able to handle higher screen resolutions while still performing well. (explain)

Radeon RX 7900 XTX		356160 Mpixels/sec
Nvidia Titan Xp		151872 Mpixels/sec
	Difference: 204288 (135%)

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 maximum amount of data (in units of megabytes per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 number of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The better 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 a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
