NVIDIA GeForce MX150 vs NVIDIA GeForce 930MX vs NVIDIA GeForce 940M

NVIDIA GeForce MX150

The Nvidia GeForce MX150 is a dedicated entry-level mobile graphics card for laptops based on the GP108 chip with the Pascal architecture. It was announced mid 2017 and is the mobile version of the desktop GeForce GT 1030. It offers the same 384 shader cores and 64 Bit memory bus manufactured in 14 nm. The clock rates and performance however are a bit higher than the desktop GT 1030. Officially it is the successor to the older Maxwell based GeForce 940MX.

Currently there are two variants of the MX150, a "normal" N17S-G1-A1 with 1468 - 1531 MHz and 25 Watt TDP and a power efficient variant named N17S-LG-A1 with 936 - 1037 MHz (-32%) and 10 Watt TDP (-60%) for thin and light laptops.

The GP108 chip is manufactured in a 14 nm FinFET process at Samsung (LPP) and offers a number of new features, including support for DisplayPort 1.4 (ready), HDMI 2.0b, HDR and improved H.265 video de- and encoding (PlayReady 3.0). 4K HDR with Netflix however wont run due to the minimum 3 GB graphics memory that is required. Compared to the bigger Pascal chips, the small GP108 does not support Simultaneous Multi-Projection (SMP) for VR and G-Sync. A full list of improvements and the new Pascal desktop GPUs is available in our dedicated Pascal architecture article.

The performance however is higher than the old GeForce GTX 950M with GDDR5 memory. Still modern and demanding games only run in low settings and resolutions fluently. E.g. Assassin's Creed Origins was only playable in lowest settings and 1280x720 pixels. Less demanding games like Call of Duty WW2 also ran in medium settings and Full HD fluently. See below for more and detailed gaming benchmarks.

The power efficient N17S-LG-A1 ULV variant is clearly slower than the normal one (due to the 32% lower boost clock).

The power consumption (25 Watt TDP of the chip alone) however lies on a level of the old 940MX (23 Watt). The older 950M and the new GTX 1050 are rated much higher with 40 Watt TDP. The GeForce MX150 also uses a small 23 x 23 mm package due to the small chip size.

NVIDIA GeForce 930MX

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.

NVIDIA GeForce 940M

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.

Architecture

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.

Performance

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.

Features

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.

Power Consumption

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.
