GeForce GTX 1630		98304 MB/sec
	Difference: 84096 (86%)

Texel Rate

The Radeon R9 380 4G should be much (more or less 95%) faster with regards to AF than the GeForce GTX 1630. (explain)

Radeon R9 380 4G		108640 Mtexels/sec
GeForce GTX 1630		55680 Mtexels/sec
	Difference: 52960 (95%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon R9 380 4G is superior to the GeForce GTX 1630, not by a very large margin though. (explain)

Radeon R9 380 4G		31040 Mpixels/sec
GeForce GTX 1630		27840 Mpixels/sec
	Difference: 3200 (11%)

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

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