Power Consumption (Max TDP)

GeForce GTX 1650		75 Watts
GeForce GTX 275		219 Watts
	Difference: 144 Watts (192%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 1650 will be 3% faster than the GeForce GTX 275 overall, because of its higher bandwidth. (explain)

GeForce GTX 1650		131072 MB/sec
GeForce GTX 275		127008 MB/sec
	Difference: 4064 (3%)

Texel Rate

The GeForce GTX 1650 is a lot (more or less 64%) better at texture filtering than the GeForce GTX 275. (explain)

GeForce GTX 1650		83160 Mtexels/sec
GeForce GTX 275		50640 Mtexels/sec
	Difference: 32520 (64%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 1650 is the winner, by a large margin. (explain)

GeForce GTX 1650		47520 Mpixels/sec
GeForce GTX 275		17724 Mpixels/sec
	Difference: 29796 (168%)

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 maximum amount of information (in units of megabytes per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the bus width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 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, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics 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 most pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
