GeForce GTX Titan vs Nvidia Titan X

Intro

Compare all that to the Nvidia Titan X, which uses a 16 nm design. nVidia has clocked the core frequency at 1417 MHz. The GDDR5X memory works at a frequency of 1251 MHz on this specific model. It features 3584 SPUs as well as 224 Texture Address Units and 96 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Performance-wise, the Nvidia Titan X should in theory be quite a bit superior to the GeForce GTX Titan overall. (explain)

Nvidia Titan X		491520 MB/sec
GeForce GTX Titan		288384 MB/sec
	Difference: 203136 (70%)

Texel Rate

The Nvidia Titan X will be quite a bit (about 69%) faster with regards to AF than the GeForce GTX Titan. (explain)

Nvidia Titan X		317408 Mtexels/sec
GeForce GTX Titan		187488 Mtexels/sec
	Difference: 129920 (69%)

Pixel Rate

The Nvidia Titan X is much (approximately 239%) better at full screen anti-aliasing than the GeForce GTX Titan, and should be able to handle higher resolutions better. (explain)

Nvidia Titan X		136032 Mpixels/sec
GeForce GTX Titan		40176 Mpixels/sec
	Difference: 95856 (239%)

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: Bandwidth is the max amount of data (counted in megabytes per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

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