GeForce GTX 1650		131072 MB/sec
	Difference: 44928 (34%)

Texel Rate

The Radeon R9 285 will be quite a bit (about 24%) better at anisotropic filtering than the GeForce GTX 1650. (explain)

Radeon R9 285		102816 Mtexels/sec
GeForce GTX 1650		83160 Mtexels/sec
	Difference: 19656 (24%)

Pixel Rate

The GeForce GTX 1650 is much (approximately 62%) more effective at FSAA than the Radeon R9 285, and also capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 1650		47520 Mpixels/sec
Radeon R9 285		29376 Mpixels/sec
	Difference: 18144 (62%)

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 max amount of data (measured in megabytes per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the bus width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. 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 are applied in one second. This figure is calculated by multiplying the total amount 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
