An apk archive revealed that HMD had the Nokia 4 and Nokia 7 Plus lined up this year. The latter has seen some time in the headlines of recent, with it touted to be powered by a Snapdragon 660, and to feature dual rear cameras. The Nokia 4 has been a lot more subdued, however, and the first actual detail of the device has surfaced, with sources claiming it will feature a Snapdragon 450.
The Snapdragon 450 was released midway through 2017. The SoC, an entry in Qualcomm's budget series, was the first 4-series SoC to be built on a 14nm manufacturing process.The Snapdragon 450 is, for all intents and purposes, an underclocked Snapdragon 625. That means it offers excellent efficiency, without sacrificing much in the performance department.
The inclusion of the Snapdragon 450 on the Nokia 4 throws a spanner into the works of HMD's naming scheme, though. The Snapdragon 450 is more powerful than the Snapdragon 430 on the Nokia 5 and 6, so it may be a tad hard for the average person to figure out where the Nokia 4 stands on the HMD pyramid.
