Intel HD Graphics 620 vs NVIDIA GeForce GTX 1080 (Desktop) vs NVIDIA GeForce GTX 1050 Mobile

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 1080 (Desktop)

The Nvidia GeForce GTX 1080 is a fast desktop graphics card based on the Pascal architecture. It was announced in May 2016 and offers all 2,560 shader of the used GP104 chip. Furthermore, the GPU is coupled with 8 GB GDDR5X graphics memory using a 256 Bit interface (10 GHz, 320 GB/s). The chip is manufactured at TSMC in 16nm (FinFET). The TDP is specified at 180 Watt and therefore slightly higher than the predecessor, the GTX 980 with 165 Watt.

NVIDIA GeForce GTX 1050 Mobile

The Nvidia GTX 1050 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 640 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 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, but the notebook model is usually a bit slower. The GeForce GTX 960M is beaten by around 30%, so the GTX 1050 is comparable to a GTX 965M 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 is roughly on par with the old GTX 960M, which would mean around 40-50 Watts and (probably due to better selection and optimized parts) therefore much 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.
