Samsung to start producing chip for Galaxy S3 successor by year's end

Samsung has started the production of the application processor that will power its next-generation flagship smartphone, which has been tentatively named the Galaxy S4, according to a report published by Korean newspaper Digital Daily.

The handset is expected to be released in the first half of next year (the S3 was released in May 2012) and the first system-on-chip, which bears the codename Adonis and will carry the Exynos 5400 series moniker, will be sampled towards the end of the year.

The SoC will be a quad-core model etched using a 28nm high-K metal gate process and will be based on the Cortex-A15.

Although the report doesn’t mention the GPU, one would expect that the chip will be a variant of the one used by the latest Chromebook, in which case it will be a Mali-T604 or a variant thereof.

The 5400 will take over from the 5250, which is manufactured using a 32nm process, and will almost certainly be the part used in future Windows RT-based tablets, Android tablets and Chromebooks.

Moving to a finer process will improve power consumption although, according to the report, there are some concerns over current leakage.
