Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically speaking, the GeForce GTX 1650 should be 147% quicker than the Radeon HD 3850 256MB in general, due to its greater data rate. (explain)

GeForce GTX 1650		131072 MB/sec
Radeon HD 3850 256MB		52992 MB/sec
	Difference: 78080 (147%)

Texel Rate

The GeForce GTX 1650 is a lot (about 678%) better at AF than the Radeon HD 3850 256MB. (explain)

GeForce GTX 1650		83160 Mtexels/sec
Radeon HD 3850 256MB		10688 Mtexels/sec
	Difference: 72472 (678%)

Pixel Rate

The GeForce GTX 1650 is much (approximately 345%) better at FSAA than the Radeon HD 3850 256MB, and also will be able to handle higher resolutions while still performing well. (explain)

GeForce GTX 1650		47520 Mpixels/sec
Radeon HD 3850 256MB		10688 Mpixels/sec
	Difference: 36832 (345%)

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 megabytes per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 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 texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the video card will be at handling 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 the video card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
