GeForce GTX 965M vs Nvidia Titan X

Intro

The GeForce GTX 965M makes use of a 28 nm design. nVidia has clocked the core speed at 944 MHz. The GDDR5 memory is set to run at a speed of 1000 MHz on this specific card. It features 1024 SPUs along with 64 TAUs and 32 ROPs.

Compare those specs to the Nvidia Titan X, which features a GPU core clock speed of 1417 MHz, and 12288 MB of GDDR5X RAM running at 1251 MHz through a 384-bit bus. It also features 3584 Stream Processors, 224 Texture Address Units, and 96 Raster Operation Units.

GeForce GTX 965M 60 Watts
Nvidia Titan X 250 Watts
Difference: 190 Watts (317%)

Memory Bandwidth

In theory, the Nvidia Titan X will be 668% quicker than the GeForce GTX 965M in general, because of its higher bandwidth. (explain)

Nvidia Titan X 491520 MB/sec
GeForce GTX 965M 64000 MB/sec
Difference: 427520 (668%)

Texel Rate

The Nvidia Titan X should be quite a bit (about 425%) faster with regards to anisotropic filtering than the GeForce GTX 965M. (explain)

Nvidia Titan X 317408 Mtexels/sec
GeForce GTX 965M 60416 Mtexels/sec
Difference: 256992 (425%)

Pixel Rate

The Nvidia Titan X should be much (approximately 350%) better at AA than the GeForce GTX 965M, and will be able to handle higher screen resolutions while still performing well. (explain)

Nvidia Titan X 136032 Mpixels/sec
GeForce GTX 965M 30208 Mpixels/sec
Difference: 105824 (350%)

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: Memory bandwidth is the largest amount of data (measured in MB per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better 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 one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
