GeForce GTX 1630 vs GeForce GTX 750 Ti

Intro

Compare those specifications to the GeForce GTX 750 Ti, which has GPU clock speed of 1020 MHz, and 2048 MB of GDDR5 RAM set to run at 1350 MHz through a 128-bit bus. It also features 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

GeForce GTX 1630		98304 MB/sec
GeForce GTX 750 Ti		86400 MB/sec
	Difference: 11904 (14%)

Texel Rate

The GeForce GTX 1630 should be quite a bit (about 36%) more effective at texture filtering than the GeForce GTX 750 Ti. (explain)

GeForce GTX 1630		55680 Mtexels/sec
GeForce GTX 750 Ti		40800 Mtexels/sec
	Difference: 14880 (36%)

Pixel Rate

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

GeForce GTX 1630		27840 Mpixels/sec
GeForce GTX 750 Ti		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: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the interface width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better 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 texture map elements (texels) that can be processed per second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at 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 can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called 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, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
