Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically speaking, the GeForce GTX 1630 should be 12% faster than the Radeon R9 M280X in general, because of its higher data rate. (explain)

GeForce GTX 1630		98304 MB/sec
Radeon R9 M280X		88000 MB/sec
	Difference: 10304 (12%)

Texel Rate

The GeForce GTX 1630 is a little bit (approximately 10%) better at anisotropic filtering than the Radeon R9 M280X. (explain)

GeForce GTX 1630		55680 Mtexels/sec
Radeon R9 M280X		50400 Mtexels/sec
	Difference: 5280 (10%)

Pixel Rate

The GeForce GTX 1630 should be a lot (about 93%) faster with regards to full screen anti-aliasing than the Radeon R9 M280X, and will be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 1630		27840 Mpixels/sec
Radeon R9 M280X		14400 Mpixels/sec
	Difference: 13440 (93%)

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 (in units of MB per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses 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 number of texture map elements (texels) that are applied per second. This is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the video 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 amount of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
