NVIDIA GeForce MX150 vs NVIDIA GeForce 930MX vs NVIDIA GeForce 920M

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 920M

The NVIDIA GeForce 920M (sometimes also NVIDIA GeForce GT 920M) is an entry level DirectX 12 graphics card. It is based on the 28 nm Kepler architecture and uses the same GK208 chip as the GeForce GT 730M, 825M and 740M. The 384 shaders are clocked at 954 MHz, while the memory (64-bit DDR3 interface) runs at 900 MHz (1800 MHz effective).

Architecture

GK208 is based on the Kepler architecture and offers two shader blocks, called SMX, each with 192 shaders for a total of 384 shader cores. The shaders are clocked at the same speed as the rest of the chip. Furthermore, the GK208 chip has 16 TMUs and 8 ROPs on a 64-bit memory interface.

PCIe 3.0 is now supported by the mobile Kepler series and GPU Boost 2.0 mode can automatically overclock the card if the laptop cooling system allows it. This feature is available on any notebook with a graphics card from the 800M series.

Performance

The GeForce 920M offers a performance similar to the AMD Radeon R7 M260 or R7 M360 and will handle modern games (as of 2014/2015) in low settings only. For comparison, a GeForce 930M is about 20 to 30 percent faster than the 920M.

Features

The feature set of the 920M corresponds to the GT 730M and 825M. This includes support for up to 4 active displays. Furthermore, high resolution monitors of up to 3840x2160 pixels can now be connected using DisplayPort 1.2 or HDMI 1.4a if available. HD-Audio codecs, such as Dolby TrueHD and DTS-HD, can be transmitted via bitstream mode through the HDMI port. However, as most laptops will feature Optimus, the integrated GPU will likely have direct control over the display ports and may limit the feature set available by the Nvidia Kepler cards.

The 5th generation PureVideo HD video processor (VP5) offers hardware decoding of HD videos. Common codecs such as MPEG-1/2, MPEG-4 ASP, H.264 and VC1/WMV9 are fully supported up to 4K resolutions while VC1 and MPEG-4 are supported up to 1080p. Two streams can be decoded in parallel for features such as Picture-in-Picture. Another feature is the inclusion of a dedicated video encoding engine similar to Intel QuickSync that can be accessed via the NVENCI API.

Power Consumption

The power consumption of the GeForce 920M is similar to the 825M and suited for 13-inch laptops and above.
