Google is expected to release at least 1 successor to the mid-range Pixel 3a, as indeed it has been for some time. Its actual launch date has been a little hard to pin down ahead, despite all the leaks about this device. However, it now seems more certain it will debut with 6GB of RAM and a mid-tier Qualcomm processor.
This is due to new sets of Geekbench 5 results that pertain to a "Google Pixel 4a", rather than to one of its supposed code-names as in prior similar leaks. However, one of these terms (sunfish) is found in their listings under the "motherboard" field. It also has a processor that identifies as the "ARM implementer 81 architecture 8 variant 13 part 2052 revision 14".
This has been associated with the 5G-capable Snapdragon 765G SoC, although it has also been linked to the 730 instead. The Pixel 4a may indeed have a 5G variant; however, it may have the code-name bramble, meaning the latter may be the case in this new leak. Therefore, it may be the best estimation of the phone's properties before its launch.
