GeForce GTX 1630 vs GeForce GTX 950M

Intro

Compare those specifications to the GeForce GTX 950M, which makes use of a 28 nm design. nVidia has set the core speed at 914 MHz. The DDR3 memory is set to run at a speed of 1000 MHz on this specific model. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 950M		55 Watts
GeForce GTX 1630		75 Watts
	Difference: 20 Watts (36%)

Memory Bandwidth

In theory, the GeForce GTX 1630 should perform much faster than the GeForce GTX 950M overall. (explain)

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

Texel Rate

The GeForce GTX 1630 should be quite a bit (more or less 52%) more effective at AF than the GeForce GTX 950M. (explain)

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

Pixel Rate

The GeForce GTX 1630 is much (about 90%) more effective at FSAA than the GeForce GTX 950M, and should be able to handle higher screen resolutions without slowing down too much. (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 largest amount of information (in units of megabytes per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at handling 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 the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
