Introducing Snapdragon W5 Gen 1 and W5+ Gen 1 – Qualcomm’s 4nm and low-power chips for wearables
News unit EMGblog.com: Last week, Qualcomm released a mysterious teaser from Announced the imminent introduction of a new chipset for smartwatches equipped with Wear OS. In confirmation of this teaser, the American company Qualcomm on Tuesday, July 19, 2022 (28 July 1401) officially released two new chips for wearable devices unveiled. These chipsets – or “platforms” as Qualcomm calls them – are the Snapdragon W5 Gen 1 and its more powerful version, the Snapdragon W5+ Gen 1. According to Qualcomm, the features of this new generation of wearable chips include longer battery life, higher performance and Less space pointed out. In the following, you will see more details of the specifications of these two chips.
Pankaj Kedia, who heads the global smart wearables business at Qualcomm. He believes that the wearables industry has continued to grow at an unprecedented rate and has provided many opportunities in many sectors. According to Kadia, the new Snapdragon W5 Gen 1 and Snapdragon W5+ Gen 1 chips are Qualcomm’s most advanced step yet. These chips have been produced with the aim of being used in the next generation of wearable devices and have considered the most critical needs of consumers, such as low consumption, high performance and integrated packaging. According to Kedia, by making these two chips, Qualcomm has actually expanded its proven hybrid architecture with new innovations in the field of consumption – such as Deep Sleep and Hibernate.
Snapdragon W5+ Gen 1 is made with 4nm lithography, compared to 12nm lithography The nanometer of the previous generation of this chip (i.e. 4100 and 4100+ – Qualcomm’s new foray into smartwatches (Snapdragon Wear 4100+) represents a significant improvement. One of the most prominent features of the Snapdragon W5+ Gen 1 is the presence of a 22nm always-on co-processor, which is generally more efficient than the 28nm co-processor in the Snapdragon Wear 4100+. According to Qualcomm, thanks to this new architecture in the Snapdragon W5+ Gen 1, the chipset offers the following improvements compared to the Snapdragon Wear 4100+:
– Up to 50% longer battery life
– Up to two times better performance
– Up to 30% less space occupation
Architecture Low consumption Bluetooth 5.3, low consumption islands for Wi-Fi, satellite navigation and voice, as well as low consumption modes such as Deep Sleep and Hibernate are other features of Snapdragon W5+ Gen 1. Of course, this is not the whole story. According to Qualcomm, the new chip can host a host of new interactive experiences – including 3D watchfaces, 3D navigation and maps, real-time scene recognition and two-way smart calling. Keyword recognition, low-power notifications and improved performance of the always-on display are also among the features of this mobile platform.
Snapdragon W5+ Gen 1 chip apparently contains 4 Cortex-A53 cores and one Cortex-M55 core (for artificial intelligence and machine learning tasks). Maybe it would have been better for Qualcomm to make this chip from Cortex-A55 or Cortex-A510, but due to the updated Snapdragon W5+ Gen 1 architecture, the chip is expected to be significantly different from the Snapdragon Wear 4100+ in terms of consumption and performance (despite the fact that in Both use Cortex-A53 cores). Needless to say, the graphics processing of Snapdragon W5+ Gen 1 is also handled by the Adreno 702 (with a clock speed of 1 GHz), which is undoubtedly more powerful than the Adreno 504 with a frequency of 320 MHz (used in the Snapdragon Wear 4100+).
Currently, Qualcomm has not mentioned the specifications of Snapdragon W5 Gen 1, But based on the differences between Snapdragon Wear 4100 and +Snapdragon Wear 4100, we can guess that Snapdragon W5 Gen 1 is practically the same as Snapdragon W5+ Gen 1, A terminal with a few less features. For example, the Snapdragon W5 Gen 1 is likely to lack a co-processor, unlike the Plus version (the same difference that can be seen between the Snapdragon Wear 4100 and its Plus version).
Finally, it should be noted Oppo and Mobvoi will be the first companies to use these two chips in their products. It is rumored that Oppo will launch Oppo Watch 3 with Snapdragon W5 Gen 1. did Snapdragon W5+ Gen 1 will also be used for the first time in the next generation TicWatch smart watch (Mobvoi product), which will probably be launched this fall.
