GeForce GTX 1630 vs GeForce GTX 970M

Intro

Compare all that to the GeForce GTX 970M, which has core clock speeds of 924 MHz on the GPU, and 1000 MHz on the 3072 MB of GDDR5 RAM. It features 1280 SPUs as well as 80 Texture Address Units and 48 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The GeForce GTX 1630 should theoretically perform a small bit faster than the GeForce GTX 970M overall. (explain)

GeForce GTX 1630		98304 MB/sec
GeForce GTX 970M		96000 MB/sec
	Difference: 2304 (2%)

Texel Rate

The GeForce GTX 970M will be much (approximately 33%) better at anisotropic filtering than the GeForce GTX 1630. (explain)

GeForce GTX 970M		73920 Mtexels/sec
GeForce GTX 1630		55680 Mtexels/sec
	Difference: 18240 (33%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 970M is a better choice, and very much so. (explain)

GeForce GTX 970M		44352 Mpixels/sec
GeForce GTX 1630		27840 Mpixels/sec
	Difference: 16512 (59%)

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 maximum amount of information (in units of MB per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

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