Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 1630 should be 514% quicker than the Radeon R5 M230 overall, due to its higher bandwidth. (explain)

GeForce GTX 1630		98304 MB/sec
Radeon R5 M230		16000 MB/sec
	Difference: 82304 (514%)

Texel Rate

The GeForce GTX 1630 will be a lot (about 257%) faster with regards to AF than the Radeon R5 M230. (explain)

GeForce GTX 1630		55680 Mtexels/sec
Radeon R5 M230		15600 Mtexels/sec
	Difference: 40080 (257%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 1630 is the winner, by far. (explain)

GeForce GTX 1630		27840 Mpixels/sec
Radeon R5 M230		3120 Mpixels/sec
	Difference: 24720 (792%)

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 data (counted in megabytes per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the bus width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR 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 of the card by the core clock 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 number of pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines 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 rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
