According to a leak on a Chinese website, local manufacturer Elephone may be the first to launch a device featuring MediaTek's recently announced Helio X20 SoC with a deca-core CPU.
Based on the leak, the Elephone P9000 is scheduled to make its debut October 20, boasting a price tag of $500. The MediaTek hardware powering the device — the MT6797 — is the successor to last year's octa-core MT6795, and features a tri-cluster architecture that includes two Cortex A72 clocked at 2.5GHz and eight Cortex A53 cores, four clocked at 2.0GHz and four at 1.4GHz.
The configuration is said to provide the ideal balance between power consumption and performance. The Cortex A53 core is already in use in several mid-range and high-end devices sold today, but the MT6797 will be one of the first SoCs to run the new Cortex A72 core. Designed as an upgrade to the Cortex A57, the Cortex A72 is faster and more energy-efficient than the outgoing A57. ARM is targeting a 2016 launch window for the A72 cores that will be built on a 16nm FinFET manufacturing process at TSMC, but the cores that will make their way onto the MT6797 will be built on a 28nm node, much like ARM's current-gen 64-bit cores such as the Cortex A53 and Cortex A57.
Other rumored specs of the Elephone P9000 include a 5.5-inch display, 4GB RAM, 32Gb storage, 20.7MP camera, 8MP front shooter, dual-SIM functionality and a 3,100mAh battery. Given that MediaTek has mentioned that the MT6797 will be sampling to manufacturers in the latter half of 2015, an October launch window seems optimistic. Until we hear more, we advise you take the information with a pinch of salt.
