GeForce GTX 860M vs GeForce GTX 965M

Intro

The GeForce GTX 860M comes with a GPU core speed of 797 MHz, and the 4096 MB of GDDR5 RAM is set to run at 1000 MHz through a 128-bit bus. It also is comprised of 1152 SPUs, 96 Texture Address Units, and 16 Raster Operation Units.

Compare those specifications to the GeForce GTX 965M, which comes with a GPU core clock speed of 944 MHz, and 2048 MB of GDDR5 memory running at 1000 MHz through a 128-bit bus. It also features 1024 Stream Processors, 64 TAUs, and 32 Raster Operation Units.

Memory Bandwidth

Both cards have exactly the same bandwidth, so in theory they should perform exactly the same. (explain)

Texel Rate

The GeForce GTX 860M is a lot (about 27%) faster with regards to anisotropic filtering than the GeForce GTX 965M. (explain)

GeForce GTX 860M 76512 Mtexels/sec
GeForce GTX 965M 60416 Mtexels/sec
Difference: 16096 (27%)

Pixel Rate

The GeForce GTX 965M should be much (approximately 137%) more effective at full screen anti-aliasing than the GeForce GTX 860M, and will be able to handle higher resolutions better. (explain)

GeForce GTX 965M 30208 Mpixels/sec
GeForce GTX 860M 12752 Mpixels/sec
Difference: 17456 (137%)

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 largest amount of information (counted in MB per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units 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 fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
