GeForce GTX 1630 vs GeForce GTX 750 Ti

Intro

Compare those specs to the GeForce GTX 750 Ti, which uses a 28 nm design. nVidia has clocked the core speed at 1020 MHz. The GDDR5 memory is set to run at a frequency of 1350 MHz on this specific card. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 750 Ti		60 Watts
GeForce GTX 1630		75 Watts
	Difference: 15 Watts (25%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 1630 is 14% faster than the GeForce GTX 750 Ti in general, due to its greater data rate. (explain)

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%) better at 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

The GeForce GTX 1630 should be a lot (about 71%) more effective at full screen anti-aliasing than the GeForce GTX 750 Ti, and should be able to handle higher 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: Bandwidth is the max amount of information (in units of MB per second) that can be moved over the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in one 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 called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
