Intel Iris Plus Graphics 655 vs NVIDIA GeForce GTX 1050 Ti Mobile vs Intel UHD Graphics 620

Intel Iris Plus Graphics 655

NVIDIA GeForce GTX 1050 Ti Mobile

The Nvidia GTX 1050 Ti is a mainstream GPU based on the Pascal architecture and was announced in January 2017. Contrary to the faster models, the GTX 1050 uses the GP107 chip, which is manufactured in a 14 nm process at Samsung.

The notebook version differs a bit in terms of clocks, but is equipped with 768 shader units, just like the desktop model. It is shipped with up to 4 GB GDDR5-VRAM attached via 128-bit interface and a 7 Gbps memory data rate (112 GB/s).

Features

The GP107 chip is manufactured in a 14 nm FinFET process at Samsung and offers a number of new features, including support for DisplayPort 1.4 (ready), HDMI 2.0b, HDR, Simultaneous Multi-Projection (SMP) as well as improved H.265 video de- and encoding (PlayReady 3.0). A full list of improvements and the new Pascal desktop GPUs is available in our dedicated Pascal architecture article.

Performance

The performance of the GeForce GTX 1050 Ti can vary quite a lot depending on the cooling performance of the laptop. It can be just as fast as the desktop model under ideal conditions. The GeForce GTX 965M and the regular GTX 1050 are beaten by around 30%, so the GTX 1050 Ti is comparable to a GTX 970M in general. It is therefore an upper mainstream GPU. Games from 2016 can be played in high settings an the Full HD resolution.

Power Consumption

The power consumption of the GeForce GTX 1050 Ti is roughly on par with the old GTX 965M, which would mean around 70 Watts and (probably due to better selection and optimized parts) therefore slightly lower compared to the desktop counterpart. This means the graphics card will usually be used for powerful multimedia notebooks and entry-level gaming systems with at least 15.4 inches.

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.
