Google Pixel 6 is expected to be powered by an in-house custom chipset, codenamed "Whitechapel". This was reported last month where we learned that Google's first custom-made SoC was being built in a partnership with Samsung SLSI (semiconductor's system large-scale integration division). Now, fresh evidence hints that the next Google Pixel 6 will be using the custom Whitechapel chipset.
In a code change submitted to the Android Open-Source Project (AOSP), one of the Googlers precisely mention “Whitechapel,” “GS101,” and “P21” in his comment, where GS101 may stand for the first chip in the "Google Silicon" line, wheres P21 may refer to Pixel 2021. The Pixel 5a can be ruled out of this as it is expected to feature a Snapdragon 765G SoC.
Past reports have claimed that it will be a 5-nm octa-core ARM processor with 2 Cortex A78 cores, 2 Cortex A76 cores, and 4 Cortex A55 cores.
