Yesterday MediaTek announced the successor to last year's Helio P10. The Helio P10 was announced back in June with devices being announced and released in the following months. Even though the SoC is only 8 months old it still looks like MediaTek is keeping up the pace and looking forward with the new P20.

Going over the specifications what we see is a slight increase in frequency on the 8 Cortex A53 cores. Although we currently lack details on the clocks of the efficiency cluster, we can disclose that the performance cluster is now clocked in at 2.3GHz instead of 2.0. On the GPU side the Mali T860MP2 has been upgraded to a T880MP2 and clocks have been raised 200MHz to 900MHz. 

Due to the lack of a big core CPU cluster or wide GPU configuration, it seems clear that the P20 is still aiming at more conservative and low-power performance targets while trying to keep the cost of the SoC down.

An interesting addition is the integration of a new memory controller which is capable of LPDDR4X memory. LPDDR4X is a new standard which was finalized late last year and represents an evolution over LPDDR4 promising to improve power efficiency. This is done by lowering the VDDQ voltage of the memory down to 0.6V, which more than halve the output driver power and cuts overall total memory power by 20%.

The multimedia blocks see some enhancement in their capabilities and can now decode and encode in 4K, although the encoder is still limited to H.264 and thus lacks HEVC capability. The ISP has also seen upgrades and now has more processing power to support up to 24MP single cameras or 13+13MP dual cameras.

Finally, the biggest news here is that the P20 is manufactured on a 16nm FinFET node. The last weeks has seen a flurry of mid-range FinFET SoCs announced and this now marks MediaTek as the third vendor after Qualcomm and Samsung LSI to release a mid-range product on a high-end manufacturing process. Here at MWC we were able to have a chat with Executive Vice President and Co-Chief Operating Officer at MediaTek Jeffrey Ju and we were told to expect some 'outstanding' power efficiency from the P20.

Commercial devices with the P20 are reported to start shipping in the second half of 2016.

    "Useless" is a false interpretation.
    I and most people believe that it is better to have few cores with some being higher power.

    Those guys are insane, such lousy core configurations. Would love to see how this performs crippled at 7 GB\s memory bandwidth. Reply

    You mean same memory bandwidth as the Snapdragon 625, Qualcomm's alternative on 14nm? Qualcomm has lower clocks too i might add. Samsung went with 1.7GHz and Mali T830 on 14nm with the 7870.
    At least MTK has the LPDDR4X option.

    Clocks don't mean performance given the same core they can have some tangible metric but even then there are custom interconnects and cache systems that can make a difference. These guys need to stop pushing the CPU arms race and focus on the GPU and memory/storage bandwidth. Reply

    Is the HEVC encoding real or fake like the Qualcomm chips? Reply
