Qualcomm announced that their flagship Snapdragon 8 Gen1 SoC is manufactured in Samsung’s 4nm foundries, but some production issues are forcing Qualcomm to move part of its production to TSMC.
According to industry insiders, Qualcomm is not happy with Samsung’s performance and is unable to produce all the necessary chipsets, so TSMC is likely to take over part of the production. However, some believe that this would have a negative effect on uniformity.
TSMC’s manufacturing process is known to be more efficient than Samsung’s in terms of power and size, so it’s easy to assume that the chips produced in TSMC’s foundries will surpass those coming out of Samsung’s fab. We have seen this happen with the iPhone 6s back in the days when TSMC and Samsung were both vendors for the A9 processor.
Then again, things may have changed over the last few years and we may not see much of a difference or anyone at all.
