Intel HD Graphics 620 vs NVIDIA GeForce GTX 1060 Mobile vs NVIDIA GeForce GTX 1070 (Desktop)

Intel HD Graphics 620

The Intel HD Graphics 620 (GT2) is an integrated graphics unit, which can be found in various ULV (Ultra Low Voltage) processors of the Kaby Lake generation. This "GT2" version of the Kaby Lake GPU is clocked at up to 1050 MHz (depending on the CPU model). 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 HD Graphics 620 depends on various factors like L3 cache size, memory configuration (DDR3/DDR4) and maximum clock rate of the specific model but is very similar to the old HD Graphics 520 GPU. That means only some less demanding recent games like Farming Simulator 17 run fluently in low detail settings (see below for gaming benchmarks). Compared to dedicated graphics cards, the HD620 should be positioned between a GeForce 910M and 920M from Nvidia. For games, the drivers however are not that fast updated and tested as with GeForce graphics cards.

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 HD Graphics 620 can be found in mobile processors specified at 15 W TDP and is therefore suited for compact laptops and ultrabooks.

NVIDIA GeForce GTX 1060 Mobile

The mobile Nvidia GeForce GTX 1060 is a graphics card for high end laptops. It is based on the Pascal architecture and manufactured in 16 nm FinFET at TSMC. The GPU is using the smaller GP106 chip. Compared to the desktop version of the GTX 1060, the laptop version offers the same amount of shaders but slightly lower clock rates. The TDP is slightly less than the old GTX 970M (predecessor).

For thin and light laptops Nvidia offer a Max-Q called version of the GTX 1060 with lower TDP and also significantly lower performance. Sadly this variant im sold with the same GTX 1060 name, making it hard to judge the performance.

The performance of the mobile GTX 1060 is a few percent below a reference GTX 1060 desktop card. In our benchmark so far (no max-Q version) the mobile GTX 1060 was somewhere between -1 and -16% slower than a desktop variant. A comprehensive review of the dekstop GeForce GTX 1060 Founders Edition with 6 GB GDDR5 can be found here. Therefore, the card is most suited for Full HD or WQHD gaming in high to maximum details (see benchmarks below).

The GP106 chip is produced in 16nm FinFET at TSMC and offers a range of new features, like DisplayPort 1.4 (ready), HDMI 2.0b, HDR, Simultaneous Multi-Projection (SMP) and improved H.265 video de- and encoding (PlayReady 3.0). A list of improvements and features can be found in our article on the Pascal architecture.

The power consumption is specified with a TGP of 80 Watt and therefore slightly below the old GTX 970M. Since summer 2017 a low power variant (Max-Q) is available for thin and light laptops with reduced performance and a lower TGP of 60 - 70 Watt.

NVIDIA GeForce GTX 1070 (Desktop)

The Nvidia GeForce GTX 1070 is the second fastest Pascal based graphics card in mid May 2016. It is a high-end desktop graphics card. The mobile pendant is also called GeForce GTX 1070, but features more shaders and a lower core clock (see this page for details on the laptop version of the GTX 1070). Both cards are based on a cut down GP104 chip as the GTX 1080 and manufactured in 16 nm FinFET at TSMC. More details on the Pascal architecture including all features and comparisons to Maxwell, can be found here.

Compared to the GTX1080, the GTX1070 features less CUDA cores (1920 versus 2560) that are clocked a bit lower (maximum Boost 1683 versus 1733). Instead of the new GDDR5X, the GTX 1070 uses slower GDDR5 graphics memory - but still 8 GB. The TDP is also reduced from 180 Watt to 150 Watt.

The performance of the GTX 1070 is between the old GTX 980 Ti and the GTX 1080. Therefore, gaming in 4k at high details is possible with the card and also VR gaming is possible.
