Intel HD Graphics 620 vs NVIDIA GeForce GTX 1050 (Desktop) vs NVIDIA GeForce GTX 1070 SLI (Laptop)

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 1050 (Desktop)

The Nvidia GeForce GTX 1050 is an entry level graphics card for desktops based on the Pascal architecture. It uses the same GP107 chip as the GTX 1050 Ti, but with only 640 instead of 768 shaders. The chip is manufactured at Samsung in 14 nm (opposed to the 16 nm TSCM based Pascal chips of the 1060 and up). The performance and specs should be similar to the GTX 1050 laptop version, that will be released later (early 2017). Compared to the faster GTX 1050 Ti, the 1050 offers less shaders (640 instead of 768) and only 2 GB of GDDR5 (instead of the 4 GB of the 1050 Ti).

Gaming benchmarks by Nvidia state that the GTX 1050 is about 30% faster on average than the Radeon RX 460 with 2 GB VRAM. The 4 GB version of the RX 460 should be about 10% slower and the older GTX 950 should reach a similar performance level as the new GTX 1050. Therefore, the GTX 1050 should be ideal for 1080p gaming with high detail settings (but not max settings).

NVIDIA GeForce GTX 1070 SLI (Laptop)

The Nvidia GeForce GTX 1070 SLI for laptops is a combination of two GTX 1070 graphics cards in SLI mode. Each card renders one frame at a time (AFR mode) but depends for most games on a good profile in the driver. Therefore, the performance can range from no gains over a single GTX 1070 to up to 90% faster performance. In most games with SLI support, the GTX 1070 SLI is therefore faster than a single GTX 1080. However, sometimes the combination also suffers from micro-stuttering.

The technical details of the card are identical to a single GTX 1070 (see for more information) and the power consumption is doubled. Therefore, the 1070 SLI combination is only found in huge clunky laptops.
