TSMC 3nm Wafer Shipments Pushed Into Q1 2023, 2.5 Years After N5 | TSMC 2nm, Samsung 2nm, And Intel 20A Battle It Out In 2025

SemiAnalysis has been hearing murmurings about TSMC’s N3 having poor yields, poor metal stack performance, being very expensive, and being too late for Apple’s 2022 iPhone. These can’t be confirmed, but we can confirm that TSMC N3 is now shipping in Q1 2023.
The hiccup on N3 brings many questions about TSMC’s competitive positioning versus Intel 20A and Samsung 2nm. Both these nodes are very aggressive and aimed at getting back into a competitive position against TSMC. Intel and Samsung even claim the nodes will bring leadership.

Apple CPU Gains Grind To A Halt And The Future Looks Dim As The Impact From The CPU Engineer Exodus To Nuvia And Rivos Starts To Bleed In

Apple’s leading CPU team looks to be struggling as they have now delivered no CPU gains for the first generation ever. Apple likely had to delay their next core architecture due due to personnel overturn from the Nuvia exodus. Furthermore, with a new exodus surrounding Rivos, the future doesn’t look so bright. Apple currently has the best client CPU cores, but can they hold this lead against stronger competition from Intel, AMD, and Qualcomm?

Rivos Inc | A Chip Off The Old Block? New RISC-V Startup Garners Many Senior CPU Architects From Apple, Google, Marvell, Qualcomm, Intel, and AMD

SemiAnalysis believes this will be the first truly high-performance RISC V design! We are still not sure what their business model is. Licensing, datacenter, mobile, or building until they are acquired by a larger firm all could be viable. Regardless, there seems to be a new, aggressive startup on the block, but this time in the RISC V flavor!

Qualcomm Lost the iPhone 12 mmWave Antenna Module Contract to a Chinese Company

iFixit’s teardown of the iPhone 12 has revealed that there are 3 mmWave antenna modules built by USI. USI is a Shanghai based SiP design and manufacturing company. This would be their first design win in the space. Apple ditching Qualcomm on this component despite using the rest of the Qualcomm X55 5G Modem RF system is quite the shocker. To emphasize the magnitude of this design win, every US phone shipment which included 5G mmWave to date has used antennas from Qualcomm.
