While the 3100 chip supported Bluetooth v4.2, the 4100 chip now includes Bluetooth v5.0. This is good news for Wear OS smartwatches as it will enable better detailed graphic display and also reduce the workload on battery and by extension longer battery life.Īnother improvement that comes with the 4100+ chip is the improved Bluetooth performance. This is a big move forward which Qualcomm claims represent 2.5x improvement in GPU performance. Display resolution has increased from 640 x 480 60fps to 1920 x 1080 30fps as a result of moving from Adreno 304 400MHz to Adreno 504 750MHz.

The next generation of Wear OS smartwatches powered by the 4100+ will have better graphics displays, thanks to the increased graphics processor. Hopefully, it gets included in the next upgrade. LPDDR4 which is faster and low-power consuming would have been a more worthwhile upgrade. The memory had been boosted from 400MHz to 750MHz, but still same LPDDR3 technology. So manufacturers would probably want to improve the camera quality.Īnother improvement that’s coming with the 4100/4100+ is a faster memory processor. Moreover, smartwatches from Kospet, Zeblaze, Lemfo, and KingWear make some of the best smartwatches with cameras. I don’t think this is actually necessary, but going by the high demand for smartwatches for kids most of which are equipped with a camera, it could be worth it. Qualcomm also doubled the ISPs to support up to 16MP camera sensor. This partitions and reduces the workload which contributes to the claimed 25% increase in battery life. One is an MDSP for Modem and GPS, while the second is an ADSP for Open Sensor Execution Environment (SEE) and audio. Secondly, Qualcomm doubled the DSPs on the 4100+ chip from one QDSP V56 to two of the same QDSP V56. Hopefully, the lags experienced on many Wear OS smartwatches become a thing of the past. This, according to Qualcomm represents an 85% increase in performance. Instead of a 32bit Arm Cortex-A7 with a 28nm process node and 1.2GHz processor, the 4100+ chip is built on a 64bit 12nm process with 1.7GHz speed. Improved CPU – 85% Increase in Performance.The 4100 chip without the co-processor will power many smartwatches for kids with fewer features where always-on display or activity tracking is not so important. The co-processor is a standalone chip, so manufacturers can actually design applications specifically for the chip. But now, both the chip and co-processor have seen significant upgrades as discussed below. This is also the difference between the 31 chip. The 41+ chips are basically the same, except that the 4100+ comes with an always-on QCC1110 co-processor that handles support for a range of sensors as well as support for sport mode as utilized by Suunto 7 and support for the dual-display architecture.
