The Core m5-6Y54 CPU is part of the Skylake generation processors and it’s part of the very power efficient SoCs from the m lineup. Due to its extremely low TDP, which can be adjusted from 3.5W up to 7W, but normally being 4.5W, the SoC can be integrated into passively cooled 2-in-1 devices, ultrabooks or tablets. The processor incorporates two cores supporting the crucial Hyper-Threading technology ticking at 1.1 GHz and can go up to 2.7 GHz for one active core and 2.7 GHz for two active cores. It’s manufactured using the latest 14nm FinFET process.
Normally the CPU can reach the core i5-6200U CPU in some short synthetic benchmark tests, but since the CPU is heavily temperature dependent, during prolonged usage the SoC won’t be able to keep up. So its performance relies quite a lot on the passive cooling system of the device.
The SoC also integrates Intel’s HD Graphics 515 GPU, codenamed GT2, with 24 EUs (Execution Units) clocked at 300 MHz and can go up to 900 MHz. Anyway, the whole SoC, including the GPU and memory controller (dual-channel LPDDR3-1866/DDR3L-1600), is rated at 4.5W TDP but it can be lowered down to 3.5W or raised as much as 7W but that’s up to the OEM that builds the machine.
