GeForce 840M vs GeForce GTX 1650

Intro

Compare that to the GeForce GTX 1650, which comes with core speeds of 1485 MHz on the GPU, and 2001 MHz on the 4096 MB of GDDR5 RAM. It features 896 SPUs as well as 56 Texture Address Units and 32 ROPs.

GeForce 840M		30 Watts
GeForce GTX 1650		75 Watts
	Difference: 45 Watts (150%)

Memory Bandwidth

Performance-wise, the GeForce GTX 1650 should theoretically be a lot better than the GeForce 840M overall. (explain)

GeForce GTX 1650		131072 MB/sec
GeForce 840M		16000 MB/sec
	Difference: 115072 (719%)

Texel Rate

The GeForce GTX 1650 is a lot (more or less 237%) better at AF than the GeForce 840M. (explain)

GeForce GTX 1650		83160 Mtexels/sec
GeForce 840M		24696 Mtexels/sec
	Difference: 58464 (237%)

Pixel Rate

The GeForce GTX 1650 is quite a bit (approximately 477%) more effective at full screen anti-aliasing than the GeForce 840M, and should be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce GTX 1650		47520 Mpixels/sec
GeForce 840M		8232 Mpixels/sec
	Difference: 39288 (477%)

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 largest amount of data (counted in MB per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed 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 processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
