Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

The GeForce RTX 4090 should in theory perform a bit faster than the GeForce RTX 3070 in general. (explain)

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

Texel Rate

The GeForce RTX 4090 will be 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

If using high levels of AA is important to you, then the GeForce RTX 4090 is the winner, and very much so. (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: Bandwidth is the largest amount of data (measured in megabytes per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
