Intel HD Graphics 620 vs NVIDIA GeForce GTX 1050 Max-Q vs Intel HD Graphics 615

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 Max-Q

The Nvidia GeForce GTX 1050 with Max-Q design is a mainstream GPU based on the Pascal architecture and was announced in January 2018. Contrary to the faster models, the GTX 1050 uses the GP107 chip, which is manufactured in a 14 nm process at Samsung.

The clock is not the only difference compared to the regular GTX 1050 though. The drivers for the Max-Q version were optimized for efficiency (and not performance; only for Max-Q models), there are optimized voltage converters for 1V operation, high-end cooling methods, and a 40 dB limit for the fan noise (with clock adjustments to ensure this at all times).

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 Max-Q should be around 10-15 % below a regular GTX 1050 for laptops. This means the GPU is most suited for full HD gaming at high settings (not maximum).

Power Consumption

The power consumption of the GeForce GTX 1050 Max-Q is rated at 34 to 40 Watt and therefore significantly lower than the normal laptop GTX 1050 (53 Watt). Therefore, the Max-Q variant is also suited for thin and light laptops.

Intel HD Graphics 615

The Intel HD Graphics 615 (GT2) is a low-end integrated graphics unit, which can be found in the Y-series of the Kaby Lake generation. This "GT2" version offers 24 Execution Units (EUs) clocked at up to 1050 MHz (depending on the CPU model). Due to its lack of dedicated graphics memory or eDRAM cache, the HD 615 has to access the main memory (2x 64bit DDR3L/LPDDR3).

Performance

The 3D performance of the HD 615 depends on the CPU model and the cooling / TDP-setting of the laptop. Furthermore, the used main memory (single channel, DDR3(L), amount) is influencing performance. On average the HD graphics 615 should be around 20 to 30 percent faster than the previous generation, the HD Graphics 615. Therefore, it may even reach the performance of the HD Graphics 520. Some low demanding games should therefore be playable with the chip.

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 m3-7Y30 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 615 can be found in Y processors with 4.5 W TDP (can be manipulated by the laptop manufacturers) and is therefore suited for very thin, mostly passively cooled 2-in-1 notebooks and tablets.
