GeForce RTX 3070		220 Watts
GeForce RTX 3090		350 Watts
	Difference: 130 Watts (59%)

Memory Bandwidth

Theoretically, the GeForce RTX 3090 should be a little bit faster than the GeForce RTX 3070 in general. (explain)

GeForce RTX 3090		958668 MB/sec
GeForce RTX 3070		(Unknown) MB/sec
	Difference: 958668 (-100%)

Texel Rate

The GeForce RTX 3090 should be a lot (approximately 66%) faster with regards to texture filtering than the GeForce RTX 3070. (explain)

GeForce RTX 3090		457560 Mtexels/sec
GeForce RTX 3070		276000 Mtexels/sec
	Difference: 181560 (66%)

Pixel Rate

The GeForce RTX 3090 is a small bit (about 9%) better at AA than the GeForce RTX 3070, and also capable of handling higher screen resolutions while still performing well. (explain)

GeForce RTX 3090		156240 Mpixels/sec
GeForce RTX 3070		144000 Mpixels/sec
	Difference: 12240 (9%)

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 largest amount of data (measured in megabytes per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video 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 Raster Operations Pipelines 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 also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
