GeForce GTX 970M vs Nvidia Titan X

Intro

Compare that to the Nvidia Titan X, which has a GPU core clock speed of 1417 MHz, and 12288 MB of GDDR5X RAM set to run at 1251 MHz through a 384-bit bus. It also is comprised of 3584 Stream Processors, 224 TAUs, and 96 Raster Operation Units.

GeForce GTX 970M		73920 Mtexels/sec
	Difference: 243488 (329%)

Pixel Rate

The Nvidia Titan X is quite a bit (approximately 207%) faster with regards to full screen anti-aliasing than the GeForce GTX 970M, and also capable of handling higher resolutions without slowing down too much. (explain)

Nvidia Titan X		136032 Mpixels/sec
GeForce GTX 970M		44352 Mpixels/sec
	Difference: 91680 (207%)

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 information (in units of megabytes per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 again. If 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 high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at 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 that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
