GeForce GTX 1630 vs GeForce GTX 970M

Intro

Compare those specs to the GeForce GTX 970M, which comes with a clock speed of 924 MHz and a GDDR5 memory frequency of 1000 MHz. It also uses a 192-bit memory bus, and makes use of a 28 nm design. It features 1280 SPUs, 80 TAUs, and 48 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Performance-wise, the GeForce GTX 1630 should theoretically be a bit superior to 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 is quite a bit (about 33%) more effective at AF 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 largest amount of information (counted in megabytes per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher 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 amount of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
