GeForce GTX 1650 vs GeForce GTX 980M

Intro

Compare all of that to the GeForce GTX 980M, which comes with a core clock speed of 1038 MHz and a GDDR5 memory frequency of 1000 MHz. It also makes use of a 256-bit bus, and uses a 28 nm design. It is comprised of 1536 SPUs, 96 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1650		75 Watts
GeForce GTX 980M		100 Watts
	Difference: 25 Watts (33%)

Memory Bandwidth

In theory, the GeForce GTX 1650 will be 2% faster than the GeForce GTX 980M overall, due to its greater bandwidth. (explain)

GeForce GTX 1650		131072 MB/sec
GeForce GTX 980M		128000 MB/sec
	Difference: 3072 (2%)

Texel Rate

The GeForce GTX 980M is a small bit (approximately 20%) faster with regards to 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

If running with lots of anti-aliasing is important to you, then the GeForce GTX 980M is the winner, by far. (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 transferred across the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. 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 amount of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output 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.
