	Difference: 20 Watts (36%)

Memory Bandwidth

In theory, the GeForce GTX 1630 should perform quite a bit faster than the GeForce GTX 750 in general. (explain)

GeForce GTX 1630		98304 MB/sec
GeForce GTX 750		80000 MB/sec
	Difference: 18304 (23%)

Texel Rate

The GeForce GTX 1630 will be a lot (more or less 71%) more effective at anisotropic filtering than the GeForce GTX 750. (explain)

GeForce GTX 1630		55680 Mtexels/sec
GeForce GTX 750		32640 Mtexels/sec
	Difference: 23040 (71%)

Pixel Rate

The GeForce GTX 1630 will be quite a bit (approximately 71%) better at full screen anti-aliasing than the GeForce GTX 750, and capable of handling higher screen resolutions while still performing well. (explain)

GeForce GTX 1630		27840 Mpixels/sec
GeForce GTX 750		16320 Mpixels/sec
	Difference: 11520 (71%)

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 max amount of data (in units of MB per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the interface width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher 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 a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
