GeForce GTX 1630 vs GeForce GTX 950M

Intro

Compare all that to the GeForce GTX 950M, which comes with GPU core speed of 914 MHz, and 2048 MB of DDR3 memory set to run at 1000 MHz through a 128-bit bus. It also features 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

GeForce GTX 950M		32000 MB/sec
	Difference: 66304 (207%)

Texel Rate

The GeForce GTX 1630 should be much (more or less 52%) more effective at texture filtering than the GeForce GTX 950M. (explain)

GeForce GTX 1630		55680 Mtexels/sec
GeForce GTX 950M		36560 Mtexels/sec
	Difference: 19120 (52%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 1630 is the winner, by far. (explain)

GeForce GTX 1630		27840 Mpixels/sec
GeForce GTX 950M		14624 Mpixels/sec
	Difference: 13216 (90%)

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 data (counted in megabytes per second) that can be moved across the external memory interface within 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, the result should be multiplied by 2 once again. If it uses 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 number of texture map elements (texels) that are processed per second. This is calculated by multiplying the total 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka 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 of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
