Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 4070 Ti		285 Watts
Radeon RX 6900 XT		300 Watts
	Difference: 15 Watts (5%)

Memory Bandwidth

The Radeon RX 6900 XT should in theory be a bit faster than the GeForce RTX 4070 Ti in general. (explain)

Radeon RX 6900 XT		524288 MB/sec
GeForce RTX 4070 Ti		516096 MB/sec
	Difference: 8192 (2%)

Texel Rate

The Radeon RX 6900 XT should be a little bit (about 5%) more effective at anisotropic filtering than the GeForce RTX 4070 Ti. (explain)

Radeon RX 6900 XT		584000 Mtexels/sec
GeForce RTX 4070 Ti		554400 Mtexels/sec
	Difference: 29600 (5%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 6900 XT is superior to the GeForce RTX 4070 Ti, and very much so. (explain)

Radeon RX 6900 XT		233600 Mpixels/sec
GeForce RTX 4070 Ti		184800 Mpixels/sec
	Difference: 48800 (26%)

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 max amount of data (measured in MB per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the interface width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. 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 ability to reach the maximum fill rate.
