GeForce GTX 950 vs Nvidia Titan X

Intro

Compare that to the Nvidia Titan X, which uses a 16 nm design. nVidia has set the core frequency at 1417 MHz. The GDDR5X RAM is set to run at a frequency of 1251 MHz on this card. It features 3584 SPUs as well as 224 TAUs and 96 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 950		90 Watts
Nvidia Titan X		250 Watts
	Difference: 160 Watts (178%)

Memory Bandwidth

Theoretically speaking, the Nvidia Titan X is 365% faster than the GeForce GTX 950 in general, due to its greater data rate. (explain)

Nvidia Titan X		491520 MB/sec
GeForce GTX 950		105728 MB/sec
	Difference: 385792 (365%)

Texel Rate

The Nvidia Titan X is a lot (about 546%) faster with regards to AF than the GeForce GTX 950. (explain)

Nvidia Titan X		317408 Mtexels/sec
GeForce GTX 950		49152 Mtexels/sec
	Difference: 268256 (546%)

Pixel Rate

The Nvidia Titan X should be a lot (more or less 315%) better at anti-aliasing than the GeForce GTX 950, and also will be able to handle higher resolutions without losing too much performance. (explain)

Nvidia Titan X		136032 Mpixels/sec
GeForce GTX 950		32768 Mpixels/sec
	Difference: 103264 (315%)

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: Memory bandwidth is the max amount of data (counted in MB per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 once 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, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is calculated 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 graphics card will be at handling 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 can possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour 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 rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
