GeForce GTX 1630 vs GeForce GTX 970M

Intro

Compare those specifications to the GeForce GTX 970M, which has GPU clock speed of 924 MHz, and 3072 MB of GDDR5 RAM running at 1000 MHz through a 192-bit bus. It also is comprised of 1280 SPUs, 80 TAUs, and 48 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The GeForce GTX 1630, in theory, should perform a bit faster than the GeForce GTX 970M in general. (explain)

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

Texel Rate

The GeForce GTX 970M should be a lot (more or less 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 using a high resolution is important to you, then the GeForce GTX 970M is the winner, by far. (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: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
