When Qualcomm officially announced the Snapdragon 8 Plus Gen 1, the biggest difference separating this SoC from the Snapdragon 8 Gen 1 was the manufacturing process. Both chipsets are mass produced on the 4nm architecture but from different vendors, and that alone appears to be the deciding factor in energy efficiency, as one tipster speaks praises of the latest silicon.

The Snapdragon 8 Gen 1 saw its fair share of performance and efficiency analysis, with results not being kind to Qualcomm’s last flagship SoC, claiming that several smartphones witnessed some level of thermal throttling. This could be attributed to the fact that the Snapdragon 8 Gen 1 was made on Samsung’s 4nm node. Apart from being inferior to TSMC’s 4nm process, Samsung was also said to be experiencing difficulty producing a large quantity of Snapdragon 8 Gen 1 shipments, which ultimately forced Qualcomm to side with TSMC.
