GeForce GTX 1630 vs GeForce GTX 750

Intro

Compare all of that to the GeForce GTX 750, which comes with GPU core speed of 1020 MHz, and 1024 MB of GDDR5 memory set to run at 1250 MHz through a 128-bit bus. It also is comprised of 512 Stream Processors, 32 TAUs, and 16 ROPs.

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

Pixel Rate

The GeForce GTX 1630 is much (approximately 71%) faster with regards to FSAA than the GeForce GTX 750, and also capable of handling higher 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 largest amount of data (in units of megabytes per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the 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 texture map elements (texels) that are applied in one second. This is calculated by multiplying the total amount of texture units of the card by the core 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 applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated 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 outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
