GeForce GTX 980M		128000 MB/sec
	Difference: 3072 (2%)

Texel Rate

The GeForce GTX 980M is a small bit (more or less 20%) better at texture filtering than the GeForce GTX 1650. (explain)

GeForce GTX 980M		99648 Mtexels/sec
GeForce GTX 1650		83160 Mtexels/sec
	Difference: 16488 (20%)

Pixel Rate

The GeForce GTX 980M will be quite a bit (approximately 40%) more effective at FSAA than the GeForce GTX 1650, and capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 980M		66432 Mpixels/sec
GeForce GTX 1650		47520 Mpixels/sec
	Difference: 18912 (40%)

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 max amount of information (counted in MB per second) that can be transported across 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 it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better 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 number of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total amount of texture units by the core 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 in one second.

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