The mid-range chips will power major smartphone brands, which will first hit the Indian market later this month.
"The smartphone gaming market is expanding, and MediaTek's G series chipsets deliver powerful performance and game-play features that let device makers innovate and cater to consumer gaming demands," Yenchi Lee, Assistant General Manager of MediaTek's Wireless Business Unit, said in a statement.
"The G series chips have an impressive combination of hardware and software to optimise performance, provide superb image quality, smooth game-play and ensure uninterrupted connectivity for dedicated gamers," added Lee.
Built on 12nm process, MediaTek's Helio G70 and G80 incorporate a pair of powerful Arm Cortex-A75 CPUs operating up to 2GHz, plus six Cortex-A55 CPUs operating at up to 1.8GHz for improved single and multi core performance.
For gaming, an efficient, high-performance Arm Mali-G52 class graphics processor operates at 820 MHz on the Helio G70 chipset and has a 15 per cent enhancement of up to 950 MHz on the Helio G80, thus, improving peak performance and ensuring a highly responsive user experience.
Both the chips also include a multitude of hardware accelerators dedicated depth engine, Camera Control Unit (CCU), Electronic Image Stabilisation (EIS) and Rolling Shutter Compensation (RSC) technology that enhances video panning and ultra-fast recording (up to 240fps).
