GeForce GTX 950M vs Nvidia Titan X

Intro

The GeForce GTX 950M comes with a core clock speed of 914 MHz and a DDR3 memory frequency of 1000 MHz. It also features a 128-bit bus, and uses a 28 nm design. It is made up of 640 SPUs, 40 TAUs, and 16 ROPs.

Compare those specifications to the Nvidia Titan X, which has a GPU core clock speed of 1417 MHz, and 12288 MB of GDDR5X memory set to run at 1251 MHz through a 384-bit bus. It also features 3584 Stream Processors, 224 TAUs, and 96 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 950M 55 Watts
Nvidia Titan X 250 Watts
Difference: 195 Watts (355%)

Memory Bandwidth

The Nvidia Titan X should in theory perform much faster than the GeForce GTX 950M in general. (explain)

Nvidia Titan X 491520 MB/sec
GeForce GTX 950M 32000 MB/sec
Difference: 459520 (1436%)

Texel Rate

The Nvidia Titan X is quite a bit (approximately 768%) more effective at anisotropic filtering than the GeForce GTX 950M. (explain)

Nvidia Titan X 317408 Mtexels/sec
GeForce GTX 950M 36560 Mtexels/sec
Difference: 280848 (768%)

Pixel Rate

If using high levels of AA is important to you, then the Nvidia Titan X is a better choice, by far. (explain)

Nvidia Titan X 136032 Mpixels/sec
GeForce GTX 950M 14624 Mpixels/sec
Difference: 121408 (830%)

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.

Memory Bandwidth: Bandwidth is the max amount of data (in units of MB per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 can be processed in one second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill 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 max fill rate.
