GeForce GTX 860M vs Nvidia Titan X

Intro

Compare those specifications to the Nvidia Titan X, which makes use of a 16 nm design. nVidia has set the core frequency at 1417 MHz. The GDDR5X memory is set to run at a speed of 1251 MHz on this particular model. It features 3584 SPUs as well as 224 TAUs and 96 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 860M		45 Watts
Nvidia Titan X		250 Watts
	Difference: 205 Watts (456%)

Memory Bandwidth

As far as performance goes, the Nvidia Titan X should in theory be a lot superior to the GeForce GTX 860M in general. (explain)

Nvidia Titan X		491520 MB/sec
GeForce GTX 860M		64000 MB/sec
	Difference: 427520 (668%)

Texel Rate

The Nvidia Titan X will be quite a bit (approximately 315%) more effective at texture filtering than the GeForce GTX 860M. (explain)

Nvidia Titan X		317408 Mtexels/sec
GeForce GTX 860M		76512 Mtexels/sec
	Difference: 240896 (315%)

Pixel Rate

If using a high resolution is important to you, then the Nvidia Titan X is a better choice, by far. (explain)

Nvidia Titan X		136032 Mpixels/sec
GeForce GTX 860M		12752 Mpixels/sec
	Difference: 123280 (967%)

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 (measured in MB per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
