Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically speaking, the GeForce GTX 1650 should be 147% faster 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 will be quite a bit (about 678%) faster with regards to anisotropic filtering 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 will be much (about 345%) more effective at AA than the Radeon HD 3850 256MB, and also able to handle higher screen resolutions without slowing down too much. (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: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better 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 applied in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The number 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 fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
