GeForce GTX 1630 vs Radeon RX 550

Intro

Compare that to the Radeon RX 550, which features GPU clock speed of 1100 MHz, and 2048 MB of GDDR5 memory set to run at 1750 MHz through a 128-bit bus. It also is comprised of 512 SPUs, 32 TAUs, and 16 ROPs.

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

Performance-wise, the Radeon RX 550 should theoretically be a little bit better than the GeForce GTX 1630 overall. (explain)

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

Texel Rate

The GeForce GTX 1630 is quite a bit (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 lots of anti-aliasing is important to you, then the GeForce GTX 1630 is superior to the Radeon RX 550, and very much so. (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: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 amount of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock 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 in one second.

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