GeForce GTX 1630 vs Radeon R9 390 8G

Intro

Compare all of that to the Radeon R9 390 8G, which uses a 28 nm design. AMD has clocked the core speed at 1000 MHz. The GDDR5 memory runs at a speed of 1500 MHz on this card. It features 2560 SPUs as well as 160 TAUs and 64 Rasterization Operator Units.

GeForce GTX 1630		98304 MB/sec
	Difference: 285696 (291%)

Texel Rate

The Radeon R9 390 8G will be a lot (about 187%) more effective at AF than the GeForce GTX 1630. (explain)

Radeon R9 390 8G		160000 Mtexels/sec
GeForce GTX 1630		55680 Mtexels/sec
	Difference: 104320 (187%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R9 390 8G is the winner, and very much so. (explain)

Radeon R9 390 8G		64000 Mpixels/sec
GeForce GTX 1630		27840 Mpixels/sec
	Difference: 36160 (130%)

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 largest amount of data (measured in MB per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
