Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 3070		220 Watts
Radeon RX 7900 XT		300 Watts
	Difference: 80 Watts (36%)

Memory Bandwidth

The Radeon RX 7900 XT should in theory be just a bit faster than the GeForce RTX 3070 overall. (explain)

Radeon RX 7900 XT		819200 MB/sec
GeForce RTX 3070		(Unknown) MB/sec
	Difference: 819200 (-100%)

Texel Rate

The Radeon RX 7900 XT should be a lot (about 83%) better at AF than the GeForce RTX 3070. (explain)

Radeon RX 7900 XT		504000 Mtexels/sec
GeForce RTX 3070		276000 Mtexels/sec
	Difference: 228000 (83%)

Pixel Rate

The Radeon RX 7900 XT will be quite a bit (approximately 100%) better at anti-aliasing than the GeForce RTX 3070, and will be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon RX 7900 XT		288000 Mpixels/sec
GeForce RTX 3070		144000 Mpixels/sec
	Difference: 144000 (100%)

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 moved past the external memory interface within a second. It is worked out by multiplying the bus width by its memory speed. In the case of DDR type RAM, the result should 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 AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the 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 maximum number of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units 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 output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
