GeForce GT 420		28800 MB/sec
	Difference: 102272 (355%)

Texel Rate

The GeForce GTX 1650 should be a lot (about 1385%) faster with regards to texture filtering than the GeForce GT 420. (explain)

GeForce GTX 1650		83160 Mtexels/sec
GeForce GT 420		5600 Mtexels/sec
	Difference: 77560 (1385%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 1650 is a better choice, and very much so. (explain)

GeForce GTX 1650		47520 Mpixels/sec
GeForce GT 420		2800 Mpixels/sec
	Difference: 44720 (1597%)

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 data (counted in megabytes per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the interface width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called 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 - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
