GeForce GTX 1650 vs GeForce GTX 980M

Intro

Compare those specs to the GeForce GTX 980M, which has GPU clock speed of 1038 MHz, and 4096 MB of GDDR5 RAM set to run at 1000 MHz through a 256-bit bus. It also features 1536 Stream Processors, 96 TAUs, and 64 ROPs.

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

Texel Rate

The GeForce GTX 980M should be a bit (about 20%) more effective at anisotropic 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 using a high screen resolution is important to you, then the GeForce GTX 980M is a better choice, and very much so. (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: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the 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 are applied in one second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core speed of the card. 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 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 max fill rate.
