GeForce GTX 950M vs Nvidia Titan X

Intro

Compare that to the Nvidia Titan X, which features core speeds of 1417 MHz on the GPU, and 1251 MHz on the 12288 MB of GDDR5X memory. It features 3584 SPUs as well as 224 Texture Address Units and 96 ROPs.

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 should be a lot faster than the GeForce GTX 950M overall. (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 (more or less 768%) more effective at texture 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 the winner, 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: Memory 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's worked out by multiplying the card's bus width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 applied in one second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock 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 is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
