MediaTek's 12nm Helio P40 series mobile chips have been adopted by Oppo and Vivo for their upcoming smartphone models, according to a report from Taiwan's TechNews.

Orders of the Helio P40 chips placed by Oppo and Vivo will help MediaTek perform better-than-expected during the first half of 2018, said the report, without citing its source.

MediaTek's revenues are expected to reach the lowest levels for 2018 in the first quarter, and will start growing in the second quarter. Meanwhile, gross margin will also begin to climb in the second quarter, according to the report.

MediaTek will likely improve its gross margin to more than 38% in 2018, when revenues are forecast to increase 6-10%, the report quoted unspecified market watchers as saying.
