Helio P30 Boosts Camera, Battery Life

September 19, 2017

MediaTek’s new Helio P30 and Helio P23 processors offer a modest upgrade over the popular Helio P20 for midrange smartphones. The P30 and P23 retain the basic eight-core architecture from the P20, packing two clusters of four CPUs: one 2.3GHz cluster and one 1.65GHz cluster. The Mali-G71 is ARM’s first GPU using its Bifrost architecture, which cuts power by up to 20% relative to the older T880 design. To save die area, the P30 uses a dual-core configuration at a top speed of 950MHz. The P23 also uses a G71 MP2 but is limited to 770MHz. MediaTek claims an overall power savings of 8–15% from the power-optimized CPUs and the new GPU.

The P30 sports the same camera subsystem as the X30, which handles dual rear-facing cameras of up to 16Mpixels each. The VPU, based on Cadence’s Vision P5 DSP and operating at 500MHz, accelerates vision-processing and deep-learning applications. The P23 lacks the VPU, and its dual cameras are limited to 13Mpixels.

Like the older P20, the new chips support 4K video encoding and decoding, 1080p displays, and two LPDDR4X-3200 memory channels. For power-efficient operation, they use the same 16nm FinFET process. The LTE modem remains at 300Mbps on the downlink using two-carrier aggregation (2xCA), but MediaTek boosted the uplink from 50Mbps to 150Mbps for faster sharing of large photos and other media. The new chips have extensive dual-SIM capability, including voice-over-LTE on both SIMs, which the company claims is an industry first. The P23 and P30 should appear in phones in 4Q17, starting with Chinese models.
