GeForce GTX 1630 vs GeForce GTX 750 Ti

Intro

Compare all of that to the GeForce GTX 750 Ti, which features a clock speed of 1020 MHz and a GDDR5 memory speed of 1350 MHz. It also makes use of a 128-bit memory bus, and makes use of a 28 nm design. It features 640 SPUs, 40 Texture Address Units, and 16 ROPs.

Texel Rate

The GeForce GTX 1630 will be much (about 36%) faster with regards to anisotropic 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

If running with a high resolution is important to you, then the GeForce GTX 1630 is a better choice, by a large margin. (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: Bandwidth is the largest amount of information (measured in MB per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
