Intel UHD Graphics 620 vs NVIDIA GeForce MX150 vs Intel Iris Plus Graphics 645

Intel UHD Graphics 620

The Intel UHD Graphics 620 (GT2) is an integrated graphics unit, which can be found in various ULV (Ultra Low Voltage) processors of the Kaby Lake Refresh generation (8th generation Core). Compared to the similar named Intel HD Graphics 620 in the 2016 Kaby Lake CPUs, only the name changed from HD to UHD. It is clocked with up to 1.150 MHz and therefore 100 MHz higher than the old HD Graphics 620 (max. 1.050 MHz) and offer a comparable performance. Due to its lack of dedicated graphics memory or eDRAM cache, the HD 620 has to access the main memory (2x 64bit DDR3/DDR4).

Performance

The exact performance of the UHD Graphics 620 depends on various factors like L3 cache size, memory configuration (DDR3/DDR4) and maximum clock rate of the specific model and as is similar to the Intel HD Graphics 620 and Intel HD Graphics 630. Compared to the average HD Graphics 620, the UHD graphics profits from the quad-core CPU a bit in our gaming benchmarks. Therefore, should be positioned between a GeForce 910M and 920M dedicated graphics card from Nvidia. For games, the drivers however are not that fast updated and tested as with GeForce graphics cards. In our tests, the UHD 620 is most suited for casual games like Team Fortress 2, Rocket League or Farming Simulator 17. See below for a list of modern games tested with various models.

Features

The revised video engine now supports H.265/HEVC Main10 profile in hardware with 10 bit colors. Furthermore, Googles VP9 codec can also be hardware decoded. The first models do not support HDCP 2.2 and therefore Netflix 4K. This was added with the new models in 2017 and beginning of May 2017 also the older CPU models like the i3-7100U are now shipped with a new S-Spec Code that supports HDCP 2.2. HDMI 2.0 however is still only supported with an external converter chip (LSPCon).

Power Consumption

The UHD Graphics 620 can be found in mobile processors specified at 15 W TDP and is therefore suited for compact laptops and ultrabooks. The power consumption during playing The Witcher 3 (with an external monitor) was comparable to a Intel HD Graphics 620 based laptop and on the lowest end of all of our measurements. Dedicated GPUs, like the GeForce 940MX, needed a lot more power.

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.
