GeForce GTX 1630 vs Radeon RX 550

Intro

Compare those specifications to the Radeon RX 550, which has GPU core speed of 1100 MHz, and 2048 MB of GDDR5 memory running at 1750 MHz through a 128-bit bus. It also is comprised of 512 SPUs, 32 TAUs, 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

In theory, the Radeon RX 550 will be 17% quicker than the GeForce GTX 1630 overall, because of its greater data rate. (explain)

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

Texel Rate

The GeForce GTX 1630 should be a lot (more or less 58%) faster with regards to AF 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 will be much (about 58%) better at anti-aliasing than the Radeon RX 550, and capable of handling higher screen resolutions more effectively. (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 (measured in MB per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better 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 number of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

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