GeForce GTX 1630 vs Radeon RX 550

Intro

Compare those specifications to the Radeon RX 550, which uses a 14 nm design. AMD has clocked the core speed at 1100 MHz. The GDDR5 memory is set to run at a frequency of 1750 MHz on this card. It features 512 SPUs as well as 32 Texture Address Units and 16 ROPs.

Radeon RX 550		35200 Mtexels/sec
	Difference: 20480 (58%)

Pixel Rate

The GeForce GTX 1630 should be a lot (approximately 58%) more effective at anti-aliasing than the Radeon RX 550, and also capable of handling higher screen resolutions better. (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 (counted in megabytes per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many 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.
