GeForce GTX 1630		75 Watts
GeForce RTX 4090		450 Watts
	Difference: 375 Watts (500%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 4090 will be 960% faster than the GeForce GTX 1630 overall, due to its higher data rate. (explain)

GeForce RTX 4090		1042432 MB/sec
GeForce GTX 1630		98304 MB/sec
	Difference: 944128 (960%)

Texel Rate

The GeForce RTX 4090 is a lot (more or less 1955%) more effective at AF than the GeForce GTX 1630. (explain)

GeForce RTX 4090		1144320 Mtexels/sec
GeForce GTX 1630		55680 Mtexels/sec
	Difference: 1088640 (1955%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce RTX 4090 is a better choice, by far. (explain)

GeForce RTX 4090		393360 Mpixels/sec
GeForce GTX 1630		27840 Mpixels/sec
	Difference: 365520 (1313%)

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 maximum amount of data (measured in megabytes per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better 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 texture map elements (texels) that are processed in one second. This number is worked out 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
