TL; DR
- Qualcomm is working with a brand-new wearable chip, the “SW6100”, likewise called “aspena”
- The cpu is not based upon any type of previous Qualcomm item, unlike its previous wearable chips
- The specifications consist of 1x Arm Cortex-A78 + 4x Arm Cortex-A55, an LPDDR5X RAM controller, all improved a TSMC procedure node
Wear OS smartwatches have actually remained in a little bit of a standstill recently. After launching Snapdragon W5/+ Gen 1 in 2022, Qualcomm hasn’t offered the system any type of focus, with just Samsung remaining to establish brand-new chips for wearables. Google smartwatches, as an example, have actually been stuck on the very same Qualcomm system for 3 years currently. There was some discuss feasible RISC-V-based SoCs in addition to next-generation chips for some time currently, yet with no concrete information.
That is, previously. Android Authority has actually seen qualified proof that Qualcomm is working with a brand-new wearables system and a few of its specifications. If it does see the light of day, it can provide the future generation of Put on OS wearables a much-needed efficiency dive.

Qualcomm Snapdragon Put on 4100 recommendation layout from my collection
Historically, Qualcomm’s wear chips have not gotten the very same focus to information as its mobile phone versions. They are commonly existing mobile phone chips with small adjustments, and some are likewise improved a more recent procedure node. Actually, a few of the earlier recommendation layouts Qualcomm gives to OEMs make use of unmodified mobile phone chips! Naturally, some job still enters into them (like enhancing sensing unit centers and cordless), yet a totally custom layout has actually never ever been a top priority for Qualcomm. The only totally personalized component of the system was the exterior coprocessor chips, yet also those were integrated in the most affordable means feasible, making use of a great deal of off-the-shelf IP.
For instance, Snapdragon W5+ Gen 1’s QCC5100 coprocessor makes use of an Arm-designed Values ML core, Tempo’s HiFi 5 DSP and Assume Silicon’s Nema|pico 2.5 D GPU, despite the fact that Qualcomm has its very own cores to do every one of these features and scaling them down for usage in a coprocessor is flawlessly feasible.
I assembled a table of Qualcomm’s previous wearable chips, in addition to the mobile phone chips I presume they are based upon:
| Wearable chip | Based upon |
|---|---|
|
Put on 2100|Put on 2500|Put on 3100 |
Snapdragon 210 |
|
Put On 4100 |
Snapdragon 429 |
|
W5 Gen 1|W5+ Gen 1 |
QCS2290 (IoT chip) |
It resembles Qualcomm may begin taking the group much more seriously currently, though. Based upon the info we watched, a brand-new chip called SW6100, codenamed Aspen, is presently in the screening stage at Qualcomm. We do not understand what the brand-new chip will certainly be called, yet my hunch is that it will certainly either be W5 Gen 2 or W6 Gen 1.
We likewise discovered a fair bit regarding it– initially, it’s based upon a TSMC procedure node. Regrettably, we do not understand which certain one it is. Whatever the instance, it needs to boost the system’s effectiveness, as Samsung procedure nodes are presently behind because location. In addition, the RAM controller was updated to sustain LPDDR5X (whereas W5 Gen 1 just sustained LPDDR4), which must provide a tiny yet non-negligible battery life increase. There’s likewise the QCC6100 coprocessor, which we regrettably do not understand anything around right now.
Qualcomm can lastly provide its wearable system the efficiency increase it seriously requires.
We likewise figured out the CPU core arrangement– 1x Arm Cortex-A78 + 4x Arm Cortex-A55. This would certainly stand for a substantial upgrade over the previous generation. Going from Cortex-A53 cores (initially presented in 2012, incidentally) to a much more recent Cortex-A55 collection with an extra huge core like Cortex-A78 must boost efficiency. Remarkably, Qualcomm isn’t the just one placing that config right into a wearable chip, as the Samsung Exynos W1000 makes use of the specific very same one.
Naturally, these cores are still dated, and it would certainly behave to see something more recent in a watch one day, yet they’re still a significant enhancement over the previous generations. Ideally, it was a determined choice to supply far better effectiveness as opposed to added efficiency that’s most likely not required in a watch anyhow.
What’s fascinating is that Qualcomm was dealing with Google to bring RISC-V wear chips to the marketplace. This leakage recommends that’s not taking place anytime quickly, if ever before. The Cortex-A78 core in SW6100 is likewise unusual– there are virtually no licensable RISC-V cores that are that effective, so it will certainly be fascinating to see just how Qualcomm manages that.
We do not understand when the brand-new chip will certainly be launched, yet if it does get to manufacturing, we can see it in Put on OS smartwatches in 2026.
