GeForce GTX 1630 vs GeForce GTX 750

Intro

Compare that to the GeForce GTX 750, which features a clock speed of 1020 MHz and a GDDR5 memory speed of 1250 MHz. It also features a 128-bit memory bus, and makes use of a 28 nm design. It features 512 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 750		55 Watts
GeForce GTX 1630		75 Watts
	Difference: 20 Watts (36%)

Memory Bandwidth

The GeForce GTX 1630, in theory, should perform a lot faster than the GeForce GTX 750 in general. (explain)

GeForce GTX 1630		98304 MB/sec
GeForce GTX 750		80000 MB/sec
	Difference: 18304 (23%)

Texel Rate

The GeForce GTX 1630 is quite a bit (more or less 71%) more effective at 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

If running with lots of anti-aliasing is important to you, then the GeForce GTX 1630 is the winner, by a large margin. (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 largest amount of data (measured in megabytes per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better 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 can be applied per second. This is calculated by multiplying the total texture units by the core 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 in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
