According to a report by WinFuture, Qualcomm plans another new chipset for Wear OS devices, even though the existing Wear 3100 is found in hardly any device. The upcoming silicon will feature 64-bit support, 12nm nodes, and Cortex A53 CPU cores, with one of two possible names: "Snapdragon Wear 429" or "Snapdragon Wear 2700". In a nutshell, it seems like this is actually going to do the platform a decent job.
Qualcomm's current Wear 3100 compares a 32-bit design with A7-based CPU cores and a larger 28nm node. When Qualcomm unveiled the 3100 last year, it was claimed that the larger node used was a deliberate decision to conserve energy, and the chip would work more efficiently in sleep mode for extended periods of time. (Actually, there should even be an energy-saving "sports mode" that never materialized.) Regardless of Qualcomm's internal logic for the larger knot last year, this rumor suggests that the price has reversed on that decision.
WinFuture states that the current test platforms (WTP2700 and WTP429W) are each paired with a gig of LPDDR3 RAM and 8GB of EMMC memory, as well as another "Track3" feature allegedly related to a power saving mechanism associated with the hardware ̵
The "Wear 429" name, as well as the other listed specifications, suggests that this new chip may be present in a redesigned or scaled-down version of the Snapdragon 429 Mobile Platform, which has the same node size and core design, and in some newer Android Cell phones and tablets were used. As a result, clock speeds of up to 2.0GHz could be supported, significantly less than 1.2GHz in the Wear 3100.
Most Wear OS today devices run the old Wear 2100 platform, and only a handful of them the new Wear 3100 was released. Given the fact that Wear 429 / Wear 2700 only exists about this rumor, we may have to wait awhile for it to arrive in Wear OS devices – assuming Wear OS still exists.
