An nameless reader quotes a report from Ars Technica: After years of repackaging the identical primary smartwatch chip again and again, Qualcomm has graced Put on OS with a contemporary smartwatch SoC. Meet the Snapdragon Put on 4100, a Qualcomm smartwatch chip that, for the primary time ever, is quicker than the earlier chip. The Put on 4100 makes use of 4 1.7GHz Cortex A53 CPUs constructed on a 12nm manufacturing course of, a serious improve from the 28nm Cortex A7s that each different Qualcomm smartwatch chip has been up till now. It is not the state-of-the-art 7nm course of that Qualcomm’s high-end chip makes use of, and the Cortex A53 is an previous CPU design, however for Qualcomm, it is a main improve. Between the brand new CPU, the Adreno 504 GPU, and quicker reminiscence, Qualcomm is promising “85% quicker efficiency” in comparison with the Put on 3100.
There are literally two variations of the 4100, the vanilla “4100” and the “4100+.” The plus model is particularly for smartwatches with an always-on watch face, and like earlier Put on SoCs, comes with an additional low-power SoC (based mostly round a Cortex-M0) to maintain the time up to date and log sensor information (like step counts). Qualcomm is promising a greater show picture high quality on this low-power mode, with extra colours and a smoother show. There are additionally twin DSPs now, which Qualcomm says are for “optimum workload partitioning, assist for dynamic clock and voltage scaling, Qualcomm Sensor Assisted Positioning PDR Wearables 2.0, low energy location monitoring assist, and an enhanced Bluetooth 5.Zero structure.” There are additionally twin ISPs with assist for 16MP sensors (on a smartwatch?). As ordinary, connectivity choices are plentiful, with onboard LTE, GPS, NFC, Wi-Fi 802.11n, and Bluetooth 5.
