Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the GeForce GTX 1630 should perform just a bit faster than the Radeon R9 M385X overall. (explain)

GeForce GTX 1630		98304 MB/sec
Radeon R9 M385X		96000 MB/sec
	Difference: 2304 (2%)

Texel Rate

The Radeon R9 M385X is a bit (approximately 11%) more effective at anisotropic filtering than the GeForce GTX 1630. (explain)

Radeon R9 M385X		61600 Mtexels/sec
GeForce GTX 1630		55680 Mtexels/sec
	Difference: 5920 (11%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 1630 is a better choice, by a large margin. (explain)

GeForce GTX 1630		27840 Mpixels/sec
Radeon R9 M385X		17600 Mpixels/sec
	Difference: 10240 (58%)

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 information (counted in MB per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
