Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1650		75 Watts
GeForce RTX 3080		320 Watts
	Difference: 245 Watts (327%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 3080 will be 494% faster than the GeForce GTX 1650 overall, due to its higher bandwidth. (explain)

GeForce RTX 3080		778547 MB/sec
GeForce GTX 1650		131072 MB/sec
	Difference: 647475 (494%)

Texel Rate

The GeForce RTX 3080 is quite a bit (more or less 371%) faster with regards to texture filtering than the GeForce GTX 1650. (explain)

GeForce RTX 3080		391680 Mtexels/sec
GeForce GTX 1650		83160 Mtexels/sec
	Difference: 308520 (371%)

Pixel Rate

The GeForce RTX 3080 is quite a bit (more or less 191%) more effective at AA than the GeForce GTX 1650, and also should be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce RTX 3080		138240 Mpixels/sec
GeForce GTX 1650		47520 Mpixels/sec
	Difference: 90720 (191%)

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 data (in units of megabytes per second) that can be transferred over the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the graphics 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 number of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
