Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the GeForce GTX 1630 should be a bit faster than the GeForce GTX 970M overall. (explain)

GeForce GTX 1630		98304 MB/sec
GeForce GTX 970M		96000 MB/sec
	Difference: 2304 (2%)

Texel Rate

The GeForce GTX 970M is a lot (more or less 33%) better at AF than the GeForce GTX 1630. (explain)

GeForce GTX 970M		73920 Mtexels/sec
GeForce GTX 1630		55680 Mtexels/sec
	Difference: 18240 (33%)

Pixel Rate

The GeForce GTX 970M will be a lot (approximately 59%) faster with regards to anti-aliasing than the GeForce GTX 1630, and should be capable of handling higher resolutions without losing too much performance. (explain)

GeForce GTX 970M		44352 Mpixels/sec
GeForce GTX 1630		27840 Mpixels/sec
	Difference: 16512 (59%)

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 max amount of information (in units of MB per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
