GeForce GTX 850M vs GeForce GTX 950M

Intro

The GeForce GTX 850M comes with a core clock frequency of 876 MHz and a DDR3 memory frequency of 1000 MHz. It also makes use of a 128-bit memory bus, and makes use of a 28 nm design. It is made up of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Compare all that to the GeForce GTX 950M, which features a core clock speed of 914 MHz and a DDR3 memory speed of 1000 MHz. It also makes use of a 128-bit bus, and makes use of a 28 nm design. It is comprised of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

GeForce GTX 850M 40 Watts
GeForce GTX 950M 55 Watts
Difference: 15 Watts (38%)

Memory Bandwidth

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

Texel Rate

The GeForce GTX 950M should be a bit (about 4%) more effective at anisotropic filtering than the GeForce GTX 850M. (explain)

GeForce GTX 950M 36560 Mtexels/sec
GeForce GTX 850M 35040 Mtexels/sec
Difference: 1520 (4%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 950M is a better choice, but only just. (explain)

GeForce GTX 950M 14624 Mpixels/sec
GeForce GTX 850M 14016 Mpixels/sec
Difference: 608 (4%)

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 (in units of megabytes per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called 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, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
