GeForce GTX 650 vs Nvidia Titan X

Intro

Compare that to the Nvidia Titan X, which uses a 16 nm design. nVidia has clocked the core speed at 1417 MHz. The GDDR5X RAM is set to run at a frequency of 1251 MHz on this particular model. It features 3584 SPUs along with 224 Texture Address Units and 96 ROPs.

Nvidia Titan X		317408 Mtexels/sec
GeForce GTX 650		33856 Mtexels/sec
	Difference: 283552 (838%)

Pixel Rate

If running with a high resolution is important to you, then the Nvidia Titan X is superior to the GeForce GTX 650, by a large margin. (explain)

Nvidia Titan X		136032 Mpixels/sec
GeForce GTX 650		16928 Mpixels/sec
	Difference: 119104 (704%)

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 max amount of data (in units of MB per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
