GeForce GTX 950M vs Nvidia Titan X

Intro

Compare that to the Nvidia Titan X, which comes with a core clock speed of 1417 MHz and a GDDR5X memory speed of 1251 MHz. It also makes use of a 384-bit bus, and makes use of a 16 nm design. It is comprised of 3584 SPUs, 224 TAUs, and 96 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 950M		55 Watts
Nvidia Titan X		250 Watts
	Difference: 195 Watts (355%)

Memory Bandwidth

Theoretically speaking, the Nvidia Titan X is 1436% faster than the GeForce GTX 950M in general, due to its greater bandwidth. (explain)

Nvidia Titan X		491520 MB/sec
GeForce GTX 950M		32000 MB/sec
	Difference: 459520 (1436%)

Texel Rate

The Nvidia Titan X should be quite a bit (about 768%) better at anisotropic filtering than the GeForce GTX 950M. (explain)

Nvidia Titan X		317408 Mtexels/sec
GeForce GTX 950M		36560 Mtexels/sec
	Difference: 280848 (768%)

Pixel Rate

If running with a high screen resolution is important to you, then the Nvidia Titan X is superior to the GeForce GTX 950M, by far. (explain)

Nvidia Titan X		136032 Mpixels/sec
GeForce GTX 950M		14624 Mpixels/sec
	Difference: 121408 (830%)

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 across the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. 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 texture map elements (texels) that are processed per second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also 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 reach the max fill rate.
