GeForce GTX 1050 3GB vs GeForce GTX 950M

Intro

Compare all of that to the GeForce GTX 950M, which comes with a clock frequency of 914 MHz and a DDR3 memory frequency of 1000 MHz. It also uses a 128-bit bus, and uses a 28 nm design. It features 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

GeForce GTX 950M		36560 Mtexels/sec
	Difference: 30256 (83%)

Pixel Rate

The GeForce GTX 1050 3GB will be much (more or less 128%) more effective at AA than the GeForce GTX 950M, and also capable of handling higher resolutions without losing too much performance. (explain)

GeForce GTX 1050 3GB		33408 Mpixels/sec
GeForce GTX 950M		14624 Mpixels/sec
	Difference: 18784 (128%)

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 information (counted in megabytes per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at 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 the video card 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 core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
