GeForce GTX 1650 vs Radeon RX 550

Intro

Compare all that to the Radeon RX 550, which has GPU clock 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 SPUs, 32 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 550		50 Watts
GeForce GTX 1650		75 Watts
	Difference: 25 Watts (50%)

Memory Bandwidth

In theory, the GeForce GTX 1650 should be 14% faster than the Radeon RX 550 in general, due to its greater bandwidth. (explain)

GeForce GTX 1650		131072 MB/sec
Radeon RX 550		114688 MB/sec
	Difference: 16384 (14%)

Texel Rate

The GeForce GTX 1650 should be a lot (more or less 136%) faster with regards to texture filtering than the Radeon RX 550. (explain)

GeForce GTX 1650		83160 Mtexels/sec
Radeon RX 550		35200 Mtexels/sec
	Difference: 47960 (136%)

Pixel Rate

The GeForce GTX 1650 should be quite a bit (approximately 170%) more effective at anti-aliasing than the Radeon RX 550, and also capable of handling higher screen resolutions more effectively. (explain)

GeForce GTX 1650		47520 Mpixels/sec
Radeon RX 550		17600 Mpixels/sec
	Difference: 29920 (170%)

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 information (in units of MB per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs 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 is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
