GeForce GTX 1630 vs Radeon RX 550

Intro

Compare all that to the Radeon RX 550, which comes with GPU core speed of 1100 MHz, and 2048 MB of GDDR5 RAM running at 1750 MHz through a 128-bit bus. It also is comprised of 512 Stream Processors, 32 TAUs, and 16 Raster Operation Units.

GeForce GTX 1630		98304 MB/sec
	Difference: 16384 (17%)

Texel Rate

The GeForce GTX 1630 is a lot (about 58%) more effective at AF than the Radeon RX 550. (explain)

GeForce GTX 1630		55680 Mtexels/sec
Radeon RX 550		35200 Mtexels/sec
	Difference: 20480 (58%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 1630 is superior to the Radeon RX 550, by a large margin. (explain)

GeForce GTX 1630		27840 Mpixels/sec
Radeon RX 550		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: Bandwidth is the maximum amount of data (in units of megabytes per second) that can be transported over the external memory interface in a second. It's worked out by multiplying the bus width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

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