GeForce GTX 1630 vs GeForce GTX 750 Ti

Intro

Compare those specifications to the GeForce GTX 750 Ti, which makes use of a 28 nm design. nVidia has set the core frequency at 1020 MHz. The GDDR5 RAM works at a speed of 1350 MHz on this card. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

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

Memory Bandwidth

As far as performance goes, the GeForce GTX 1630 should in theory be a bit superior to the GeForce GTX 750 Ti overall. (explain)

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

Texel Rate

The GeForce GTX 1630 will be quite a bit (approximately 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 using a high screen resolution is important to you, then the GeForce GTX 1630 is a better choice, by far. (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 (counted in megabytes per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total number of texture units of the card by the core clock 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 applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the clock 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 also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
