Theoretically speaking, the GeForce GTX 1650 is 82% quicker than the Radeon R7 250X 2GB overall, because of its higher data rate. (explain)

GeForce GTX 1650		131072 MB/sec
Radeon R7 250X 2GB		72000 MB/sec
	Difference: 59072 (82%)

Texel Rate

The GeForce GTX 1650 should be quite a bit (more or less 108%) faster with regards to texture filtering than the Radeon R7 250X 2GB. (explain)

GeForce GTX 1650		83160 Mtexels/sec
Radeon R7 250X 2GB		40000 Mtexels/sec
	Difference: 43160 (108%)

Pixel Rate

The GeForce GTX 1650 should be much (more or less 197%) more effective at full screen anti-aliasing than the Radeon R7 250X 2GB, and also will be able to handle higher resolutions while still performing well. (explain)

GeForce GTX 1650		47520 Mpixels/sec
Radeon R7 250X 2GB		16000 Mpixels/sec
	Difference: 31520 (197%)

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 data (counted in megabytes per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total texture units by the core speed of the chip. The higher the texel rate, 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 most pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant 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.
