GeForce GTX 880M vs Nvidia Titan X

Intro

Compare all that to the Nvidia Titan X, which has GPU core speed of 1417 MHz, and 12288 MB of GDDR5X RAM running at 1251 MHz through a 384-bit bus. It also is comprised of 3584 SPUs, 224 Texture Address Units, and 96 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 880M		130 Watts
Nvidia Titan X		250 Watts
	Difference: 120 Watts (92%)

Memory Bandwidth

Theoretically, the Nvidia Titan X should be quite a bit faster than the GeForce GTX 880M in general. (explain)

Nvidia Titan X		491520 MB/sec
GeForce GTX 880M		128000 MB/sec
	Difference: 363520 (284%)

Texel Rate

The Nvidia Titan X will be a lot (about 160%) faster with regards to anisotropic filtering than the GeForce GTX 880M. (explain)

Nvidia Titan X		317408 Mtexels/sec
GeForce GTX 880M		122112 Mtexels/sec
	Difference: 195296 (160%)

Pixel Rate

If running with 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 880M		30528 Mpixels/sec
	Difference: 105504 (346%)

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 max amount of information (in units of megabytes per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
