GeForce RTX 3070		220 Watts
GeForce RTX 4090		450 Watts
	Difference: 230 Watts (105%)

Memory Bandwidth

In theory, the GeForce RTX 4090 will be -100% quicker than the GeForce RTX 3070 in general, due to its higher bandwidth. (explain)

GeForce RTX 4090		1042432 MB/sec
GeForce RTX 3070		(Unknown) MB/sec
	Difference: 1042432 (-100%)

Texel Rate

The GeForce RTX 4090 is quite a bit (approximately 315%) faster with regards to AF than the GeForce RTX 3070. (explain)

GeForce RTX 4090		1144320 Mtexels/sec
GeForce RTX 3070		276000 Mtexels/sec
	Difference: 868320 (315%)

Pixel Rate

The GeForce RTX 4090 will be quite a bit (about 173%) more effective at AA than the GeForce RTX 3070, and should be capable of handling higher screen resolutions more effectively. (explain)

GeForce RTX 4090		393360 Mpixels/sec
GeForce RTX 3070		144000 Mpixels/sec
	Difference: 249360 (173%)

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 largest amount of data (measured in MB per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total texture units of the card by the core 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 applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
