GeForce GTX 650 vs Nvidia Titan X

Intro

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 650		64 Watts
Nvidia Titan X		250 Watts
	Difference: 186 Watts (291%)

Memory Bandwidth

In theory, the Nvidia Titan X is 514% quicker than the GeForce GTX 650 overall, because of its higher data rate. (explain)

Nvidia Titan X		491520 MB/sec
GeForce GTX 650		80000 MB/sec
	Difference: 411520 (514%)

Texel Rate

The Nvidia Titan X should be quite a bit (approximately 838%) better at AF than the GeForce GTX 650. (explain)

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

Pixel Rate

If using a high screen resolution is important to you, then the Nvidia Titan X is a better choice, and very much so. (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 information (in units of megabytes per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total number of 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

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