Updated | Qualcomm Snapdragon Wear 5100 leaks as Snapdragon Wear W5 Gen 1 with generational battery life, performance and efficiency gains
Last week, Qualcomm teased the release of a new Snapdragon Wear chipset, having offered the Wear 4100 and Wear 4100+ platforms to OEMs for nearly two years at this point. While Qualcomm has not yet confirmed any details about any new smartwatch chipset, Evan Blass has shared three release slides on Twitter.
Previously believed to be the Snapdragon Wear 5100 and Wear 5100+, Qualcomm has re-branded future smartwatch SoCs in the same way it did last year with its smartphone ones. Hence, the Snapdragon W5 Gen 1 and W5+ Gen 1 will replace the Wear 4100 and Wear 4100+, respectively. As expected, Qualcomm has made numerous changes from the Wear 4100 series, albeit while retaining its ARM Cortex-A53 CPU cores.
On the one hand, both W5 Gen 1 chipsets utilise an Adreno 702 GPU clocked at 1 GHz, up from the 320 MHz that the outgoing Adreno A504 offers. Additionally, the W5 Gen 1 series supports LPDDR4X RAM running at 2,133 MHz, which should provide Wear OS with considerably more bandwidth than the Snapdragon Wear 4100 platforms currently do. Incidentally, the W5+ Gen 1 gains a Cortex-M55 co-processor with a 250 MHz clock speed, compared to the Cortex-M0 that peaks at 50 MHz.
On the other hand, the switch to 4 nm and 22 nm process nodes allows the W5 Gen 1 series to deliver 50% power improvements on a 30% smaller package. Separately, one slide outlines the various collaborations Qualcomm has engaged in, such as 'Find My Device' functionality with Tile. Moreover, another slide states that there are over two dozen W5 Gen 1-based smartwatch designs in the pipeline, with Mobvoi and Oppo delivering the first of these. Presumably, the first Snapdragon W5 Gen 1 and W5+ Gen 1 smartwatches will arrive this autumn.
