GeForce GTX 1630 vs Radeon RX 550

Intro

Compare those specifications to the Radeon RX 550, which features a clock speed of 1100 MHz and a GDDR5 memory frequency of 1750 MHz. It also features a 128-bit bus, and uses a 14 nm design. It is made up of 512 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 550		50 Watts
GeForce GTX 1630		75 Watts
	Difference: 25 Watts (50%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 550 should be 17% faster than the GeForce GTX 1630 overall, because of its higher bandwidth. (explain)

Radeon RX 550		114688 MB/sec
GeForce GTX 1630		98304 MB/sec
	Difference: 16384 (17%)

Texel Rate

The GeForce GTX 1630 should be quite a bit (more or less 58%) better at anisotropic filtering than the Radeon RX 550. (explain)

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

Pixel Rate

The GeForce GTX 1630 is much (about 58%) more effective at full screen anti-aliasing than the Radeon RX 550, and also should be capable of handling higher screen resolutions while still performing well. (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 largest amount of data (in units of megabytes per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, 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 that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the clock 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 fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
