GeForce GTX 1630		75 Watts
GeForce GTX 470		215 Watts
	Difference: 140 Watts (187%)

Memory Bandwidth

As far as performance goes, the GeForce GTX 470 should in theory be much superior to the GeForce GTX 1630 in general. (explain)

GeForce GTX 470		133920 MB/sec
GeForce GTX 1630		98304 MB/sec
	Difference: 35616 (36%)

Texel Rate

The GeForce GTX 1630 will be quite a bit (about 64%) more effective at texture filtering than the GeForce GTX 470. (explain)

GeForce GTX 1630		55680 Mtexels/sec
GeForce GTX 470		33992 Mtexels/sec
	Difference: 21688 (64%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 1630 is the winner, but only just. (explain)

GeForce GTX 1630		27840 Mpixels/sec
GeForce GTX 470		24280 Mpixels/sec
	Difference: 3560 (15%)

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 information (in units of megabytes per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better 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 texture map elements (texels) that are applied in one second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the graphics 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 amount of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
