According to the rumours, LG is flat out trying to get the chip ready and avoid all the mess it made with the first generation Nuclun.

LG has been working with Intel and TSMC, and created two Nuclun 2 chips. The one made by Chipzilla had the best performance, but Intel didn’t get the contract.

Intel’s Nuclun 2 was based on the Cortex-A53 and Cortex-A72 cores which are working together in heterogeneous computing big.LITTLE architecture.

Intel’s SoC is using a 14nm FinFET tech, and is running at 2.4GHz and would throw in a XMM 7360 modem with support for category 10 4G LTE connectivity speeds.
TSMC’s flavour used a 16nm manufacturing process, and the CPU is running at 2.1GHz so Chipzilla should have won hand’s down.

The rumour is that LG did not think that Intel could manage the high production capacity and gave the contract to TSMC.
