After shedding the job of constructing the Snapdragon 8 Gen 1 chipset to TSMC in 2022 due to its low yield fee, Samsung Foundry improved its efficiency a lot that this previous April a report mentioned that (*4*) to twin-supply the Snapdragon 8 Gen 4 SoC for subsequent yr. However in August, one tipster mentioned that each one Snapdragon 8 Gen 4 utility processors (AP) would be produced by Samsung Foundry utilizing its extra superior 3nm Gate All-Round (GAA) course of node.
Not like TSMC’s FinFET transistors used with its 3nm course of node, the GAA transistors used by Samsung embrace vertically positioned horizontal nanosheets that enable the gate to encompass the channel on all 4 sides (it is only three sides with FinFET). This helps scale back present leakage and will increase the drive present leading to higher-performing chips that do not devour as a lot vitality. TSMC will not be switching to GAA transistors till it begins producing chips at 2nm.
At present, now we have a brand new rumor to move alongside. To recap, to this point now we have heard that the Snapdragon 8 Gen 4 SoC will be twin-sourced. Then we heard that Samsung Foundry would get the job. Now, Taiwan’s Tech News (by way of AndroidAuthority) says that TSMC will get the nod from Qualcomm to be the lone producer of its subsequent flagship AP, the Snapdragon 8 Gen 4. Supposedly, the chip will be produced utilizing TSMC’s 3nm course of node.
Qualcomm continues to be interested by twin-sourcing its flagship AP however not till 2025
San Diego-primarily based Qualcomm has lots using on the Snapdragon 8 Gen 4 chipset. It can be the primary to sport Qualcomm’s customized Oryon cores so you already know that there are going to be loads of eyeballs taking a look at Geekbench outcomes to see how the AP performs no matter which foundry the element is coming from.
For you twin-sourcing followers on the market (and we know that you just’re on the market…someplace), the excellent news is that Qualcomm hasn’t given up on having each TSMC and Samsung Foundry construct its flagship AP. Tech Information says that twin-sourcing has merely been pushed again to 2025 for the manufacturing of the Snapdragon 8 Gen 5 AP.
For those who’re questioning whether or not twin-sourcing has been used to produce chipsets for a serious smartphone earlier than, in 2015 Apple twin-sourced the A9 SoC from each TSMC and Samsung for the iPhone 6s and iPhone 6s Plus. The chip was made by Samsung Foundry utilizing its 14 nm FinFET LPE course of and by TSMC on its 16 nm FinFET course of.
