New TriCluster Deca-Core CPU For Smartphone

Smartphones have become an integral part for staying connected round the clock which has led to quest for a longer battery power and an efficient smooth experience. Looking forward to meet the following demand, MediaTek has announced the launch of Helio X20 — the world’s first mobile processor with Tri-Cluster CPU architecture and ten processing cores (Deca-core). Referring to the release, Helio X20 boasts several features designed to maximise device display performance and enhance the multimedia experience for the consumer. According to the media release, “The Tri-Cluster CPU architecture is enabled by MediaTek’s new CorePilot 3.0 heterogeneous computing scheduling algorithm. CorePilot 3.0 schedules the tasks for all CPUs and GPUs on the SoC while managing power and thermal effects so that extreme performance can be attained while creating less heat. It provides up to a 30 per cent reduction of power consumption compared with conventional dual cluster architectures.”

Referring to the MediaTek datasheet, “The Tri-Cluster CPU architecture in the Helio X20 provides three processor clusters, each designed to more efficiently handle different types of workloads. The Tri-Cluster CPU consists of one cluster of two ARM Cortex-A72 cores (running at 2.5GHz for extreme performance) and two clusters of four ARM Cortex-A53 cores (one running at 2.0GHz for medium loads and one running at 1.4GHz for light activities). Each cluster is designed to more efficiently handle different types of workloads. Much like adding gears to vehicles, dividing the cores into three clusters provides a more efficient allocation of tasks for optimum performance and extended battery life. It can delegate simple tasks to one cluster of cores, while directing more-complex (and more-power-hungry) tasks to the other clusters. If the smartphone is doing only simple tasks – such as sending text messages or running the calculator – on one cluster, the other clusters can power down, and therefore drive smoother performance and extended battery life.”

The Helio X20 features include:

  • Dual main cameras with a built-in 3D depth engine that allows for a faster shot-to-shot experience in creating complex depth-of-field images
  • Multi-scale de-noise engines to deliver high quality images with unprecedented detail, color accuracy, and sharpness even under extreme conditions
  • A 120Hz mobile display that breaks the barriers of the current 60Hz refresh rate to provide crisp and responsive browsing and uncompromising motion viewing
  • An integrated, low power sensor processor – ARM Cortex-M4 – to support diverse always-on applications such as MP3 playback and voice activation. The sensor hub operates on an isolated, low power domain to assist with tasks for better battery efficiency
