GeForce GTX 1650 vs Radeon RX 550

Intro

Compare those specifications to the Radeon RX 550, which makes use of a 14 nm design. AMD has set the core frequency at 1100 MHz. The GDDR5 RAM works at a speed of 1750 MHz on this particular card. It features 512 SPUs along with 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% quicker than the Radeon RX 550 overall, 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 will be quite a bit (more or less 136%) more effective at 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 a lot (about 170%) better at full screen anti-aliasing than the Radeon RX 550, and capable of handling higher 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 maximum amount of information (in units of MB per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the bus width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 amount of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
