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.
