Snapdragon W5+ Gen 1 is a boost for Wear OS w/ 4nm SoC


Qualcomm’s subsequent chip for smartwatches is the Snapdragon W5+ Gen 1, and it’s a significant development from what got here earlier than.

The chipmaker begins by dropping its earlier naming scheme (e.g., Put on 2100, 3100, 4100+) for “W5+” adopted by the “Gen,” which is in keeping with the conference for smartphones.

Notably, the Snapdragon W5+ Gen 1 has a 4nm SoC (system on a chip) in an enormous improve from the 4100+’s 12nm (and 28nm earlier than that). Qualcomm isn’t naming the foundry, however there are 4 A53 cores at 1.7GHz with twin Adreno 702 GPUs (1GHz) and almost thrice quicker reminiscence (LPDDR 750MHz to 2133MHz). In all, two instances increased efficiency is touted.

This SW5100 SoC permits for responsive app scrolling, clean 1080p video playback, real-time picture recognition, and even two-way video calling (twin ISP supporting 16+16MP assist). It will possibly additionally assist “3D watch faces” and maps with navigation.

The opposite main facet of the W5+ Gen 1 is its hybrid structure with the 22nm (from 28nm on the 4100+) always-on co-processor operating a real-time OS. The QCC5100 encompasses a Cortex M55 core, its personal “2.5D” GPU, U55 machine studying core, and handles Bluetooth 5.3 immediately. 

Along with dealing with sensors (e.g., coronary heart price, accelerometer, and gyroscope) and the always-on show, this part is now liable for audio (music playback) and delivering low-power notifications. 

Consequently, the W5+ makes use of 30-60% much less energy than the 4100+ in widespread use circumstances. This consists of the always-on show (42% much less), background notifications (-57%), Bluetooth music (-36%), GPS location (-42%), show scrolling (-41%), and VoLTE calling (-34%). Moreover 50% longer battery life, the W5+ is a bodily smaller chip by 30% that permits for thinner designs and even a single international LTE modem SKU. 

Qualcomm can also be providing the Snapdragon W5 Gen 1, which lacks the co-processor, to producers of wearables for the Chinese language market, seniors, youngsters, well being, and enterprise. Throughout each chips, over 25 designs are within the pipeline, and W5+ Gen 1 is already within the mass manufacturing stage.

The chipmaker labored with Compal and Pegatron on reference designs to hurry up growth, whereas Google is enthusiastic:

Google and Qualcomm Applied sciences have a longstanding historical past of serving to our companions ship nice person experiences. We applaud the technological breakthroughs that Qualcomm Applied sciences is bringing to the wearables business with the launch of its Snapdragon W5+ platform,” stated Bjorn Kilburn, GM and Senior Director of Put on OS at Google. “With the Snapdragon W5+ platform, we’re excited for what’s attainable in bringing new ranges of efficiency, functionality and battery life to Put on OS smartwatches.

Mobvoi shall be making the primary Put on OS gadget powered by the Snapdragon W5+ Gen 1 this fall and you may be taught extra about that right here.
