GeForce GTX 1630 vs GeForce GTX 750

Intro

Compare all of that to the GeForce GTX 750, which uses a 28 nm design. nVidia has clocked the core speed at 1020 MHz. The GDDR5 RAM works at a speed of 1250 MHz on this model. It features 512 SPUs as well as 32 TAUs and 16 Rasterization Operator Units.

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

Texel Rate

The GeForce GTX 1630 should be much (more or less 71%) faster with regards to texture 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 much (approximately 71%) faster with regards to AA than the GeForce GTX 750, and should be able to handle 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: Memory bandwidth is the max amount of information (measured in MB per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better 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 can be applied per second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a 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. Pixel rate is calculated by multiplying the number of Render Output Units by the the core clock speed. 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 is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
