GeForce GTX 1630 vs GeForce GTX 970M

Intro

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

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the GeForce GTX 1630 should be just a 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 should be a lot (approximately 33%) better at texture 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 high levels of AA is important to you, then the GeForce GTX 970M is a better choice, by a large margin. (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 max amount of information (measured in megabytes per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out 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 rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
