GeForce 940M vs Nvidia Titan X

Intro

Compare those specifications to the Nvidia Titan X, which features clock speeds of 1417 MHz on the GPU, and 1251 MHz on the 12288 MB of GDDR5X memory. It features 3584 SPUs as well as 224 Texture Address Units and 96 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Nvidia Titan X should perform quite a bit faster than the GeForce 940M overall. (explain)

Nvidia Titan X		491520 MB/sec
GeForce 940M		16000 MB/sec
	Difference: 475520 (2972%)

Texel Rate

The Nvidia Titan X is a lot (approximately 1134%) more effective at AF than the GeForce 940M. (explain)

Nvidia Titan X		317408 Mtexels/sec
GeForce 940M		25728 Mtexels/sec
	Difference: 291680 (1134%)

Pixel Rate

If running with a high resolution is important to you, then the Nvidia Titan X is superior to the GeForce 940M, by a large margin. (explain)

Nvidia Titan X		136032 Mpixels/sec
GeForce 940M		8576 Mpixels/sec
	Difference: 127456 (1486%)

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.

Price Comparison

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster 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 number of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total texture units of the card by the core clock 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 in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
