GeForce GTX 1630 vs Radeon R9 M390X

Intro

Compare all that to the Radeon R9 M390X, which makes use of a 28 nm design. AMD has set the core speed at 723 MHz. The GDDR5 RAM runs at a speed of 1250 MHz on this particular model. It features 2048 SPUs along with 128 TAUs and 32 ROPs.

GeForce GTX 1630		75 Watts
Radeon R9 M390X		125 Watts
	Difference: 50 Watts (67%)

Memory Bandwidth

As far as performance goes, the Radeon R9 M390X should theoretically be much superior to the GeForce GTX 1630 overall. (explain)

Radeon R9 M390X		160000 MB/sec
GeForce GTX 1630		98304 MB/sec
	Difference: 61696 (63%)

Texel Rate

The Radeon R9 M390X should be quite a bit (more or less 66%) better at anisotropic filtering than the GeForce GTX 1630. (explain)

Radeon R9 M390X		92544 Mtexels/sec
GeForce GTX 1630		55680 Mtexels/sec
	Difference: 36864 (66%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 1630 is the winner, not by a very large margin though. (explain)

GeForce GTX 1630		27840 Mpixels/sec
Radeon R9 M390X		23136 Mpixels/sec
	Difference: 4704 (20%)

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 (in units of MB per second) that can be moved across the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the 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 texture map elements (texels) that are processed in one second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

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