The NVIDIA GeForce 910M is an entry-level DirectX 12 compatible graphics card announced in late 2015. Its core is based on the 28nm GF117 chip (Fermi architecture) and is equipped with 64-bit DDR3 memory. The 910M is a renamed GeForce 820M, which already was based on the the old GT 620M, GT 720M and GeForce 710M.
The GF117 is based on the optimized GF108 Fermi chip (GeForce GT 540M) and offers 96 shaders, 16 TMUs and 4 ROPs. Each shader core is clocked twice as fast as the rest of the graphics chip, a technique known as hot clocking. More detailed information on Fermi can be found on the GT 435M GPU page.
It should be noted that the GF117 does not offer dedicated graphic ports and can therefore only be used in conjunction with Optimus.
The 820M supports GPU Boost 2.0, which can automatically overclock the card if the laptop cooling system allows it.
The gaming performance should be identical to the old GeForce 820M (see this page for benchmarks and game tests) and therefore also GT 720M and the Intel Iris Graphics 5100. This places the card in the entry level segment. Only old or low demanding games run fluent on this graphics card.
The shader cores (also called CUDA cores) can be used for general calculations with APIs such as CUDA, DirectCompute 2.1 and OpenCL. PhysX is theoretically possible, but the 910M is too slow to handle both PhysX and 3D rendering in modern games. 3D Vision is not supported according to Nvidia.
The power consumption of the Geforce 910M should be similar to the old 820M and GT 720M. As a result, the GPU is best suited for notebooks 13 inches in size or greater. The efficiency however cant be compared to a modern Maxwell based GPU like the GeForce 920MX.

The Nvidia GeForce 930MX is an entry-level DirectX 12 graphics card for laptops that was announced in the first quarter of 2016. It is the refresh of the GeForce 930M and now supports GDDR5 graphics memory. It is based on the same GM108 chip and may feature slightly increased clock rates.
The performance will depend on the used graphics memory. With fast GDDR5 it should be similar or slightly faster than the Maxwell GPU in the Surface Book. With DDR3 it performs be somewhere between the old 930M and 940M. That means that only non demanding games of 2017 run fluently (in lowest detail settings) on the GeForce 930M. Games with low demands like Dota 2 or Path of Exile should run in higher detail settings and resolution.
The power consumption should be quite similar to the 930M and 940M and therefore also suited for smaller laptops.

The NVIDIA GeForce 940M is a mid-range DirectX 11-compatible graphics card for laptops unveiled in March 2015. It is based on Nvidia's Maxwell architecture (GM108 chip) and manufactured in 28 nm. The 940M offers 384 shader units as well as 2 GB of DDR3 memory (64 bit, 2000 MHz effective).
Compared to the previous and technically very similar GeForce 840M, the GeForce 940M is clocked just slightly higher.
Compared to Kepler, Maxwell has been optimized in several details to increase power efficiency. Smaller Streaming Multiprocessors (SMM) with only 128 ALUs (Kepler: 192) and an optimized scheduler should lead to better utilization of the shaders. Nvidia promises that a Maxwell SMM with 128 ALUs can offer 90 percent of the performance of a Kepler SMX with 192 ALUs. GM108 features 3 SMMs and thus 384 shader cores, 24 TMUs and 8 ROPs (64-bit interface).
Another optimization is the massively enlarged L2 cache. The larger size can process some of the memory traffic to allow for a relatively narrow memory interface without significantly reducing performance.
Similar to Fermi and Kepler, the GM107/GM108 support DirectX 12 with feature level 11_0 only.
Due to its just 5 percent higher core clock, the GeForce 940M is only marginally faster than the previous GeForce 840M and similar to the older GeForce GT 750M (DDR3 version). Many games of 2014/2015 can be played fluently in WXGA resolution (1366 x 768) and medium detail settings. However, very demanding games such as Assassin's Creed Unity will require lower resolutions and/or details.
GM108 integrates the sixth generation of the PureVideo HD video engine (VP6), offering a better decoding performance for H.264 and MPEG-2 videos. Of course, VP6 supports all features of previous generations (4K support, PIP, video encoding via NVENC API). Unfortunately, HDMI 2.0 is still not supported.
The power consumption of the GeForce 940M should be about 30 Watts or lower. Therefore, the GPU is best suited for laptops 13 - 14 inches in size and above. The 900M series also supports Optimus to automatically switch between an integrated graphics card and the Nvidia GPU.
