GeForce GTX 880M vs Nvidia Titan X

Intro

Compare all of that to the Nvidia Titan X, which makes use of a 16 nm design. nVidia has set the core speed at 1417 MHz. The GDDR5X RAM is set to run at a frequency of 1251 MHz on this model. It features 3584 SPUs as well as 224 TAUs and 96 Rasterization Operator 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 speaking, the Nvidia Titan X is 284% quicker than the GeForce GTX 880M in general, because of its higher bandwidth. (explain)

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

Texel Rate

The Nvidia Titan X is much (approximately 160%) more effective at AF than the GeForce GTX 880M. (explain)

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

Pixel Rate

The Nvidia Titan X will be quite a bit (about 346%) faster with regards to AA than the GeForce GTX 880M, and also should be able to handle higher resolutions without losing too much performance. (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: Bandwidth is the maximum amount of data (measured in megabytes per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total amount of texture units of the card 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 processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write 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 core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
