GeForce GTX 860M vs Nvidia Titan X

Intro

Compare all of that to the Nvidia Titan X, which has a core clock speed of 1417 MHz and a GDDR5X memory frequency of 1251 MHz. It also features a 384-bit bus, and uses a 16 nm design. It is comprised of 3584 SPUs, 224 Texture Address Units, and 96 ROPs.

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

Memory Bandwidth

In theory, the Nvidia Titan X is 668% quicker than the GeForce GTX 860M in general, because of its greater data rate. (explain)

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

Texel Rate

The Nvidia Titan X should be a lot (about 315%) more effective at AF than the GeForce GTX 860M. (explain)

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

Pixel Rate

The Nvidia Titan X will be much (about 967%) better at FSAA than the GeForce GTX 860M, and will be able to handle higher screen resolutions without slowing down too much. (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 (in units of MB per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory speed. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total number of texture units by the core 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 applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
