Power Consumption (Max TDP)

GeForce 840M		30 Watts
GeForce GTX 1630		75 Watts
	Difference: 45 Watts (150%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 1630 is 514% faster than the GeForce 840M in general, due to its higher data rate. (explain)

GeForce GTX 1630		98304 MB/sec
GeForce 840M		16000 MB/sec
	Difference: 82304 (514%)

Texel Rate

The GeForce GTX 1630 should be quite a bit (more or less 125%) faster with regards to texture filtering than the GeForce 840M. (explain)

GeForce GTX 1630		55680 Mtexels/sec
GeForce 840M		24696 Mtexels/sec
	Difference: 30984 (125%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 1630 is superior to the GeForce 840M, by a large margin. (explain)

GeForce GTX 1630		27840 Mpixels/sec
GeForce 840M		8232 Mpixels/sec
	Difference: 19608 (238%)

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 (counted in megabytes per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, the result 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 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 processed per second. This figure is worked out by multiplying the total texture units of the card by the core clock 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 in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
