Apple Inc. (NASDAQ:AAPL) kickstarted its virtual  Worldwide Developer's Conference Monday, and an analyst at BofA Securities sifted through the announcements to analyze their ramifications for the semiconductor sector.

Intel Logged Out of Macs: Apple's decision to replace Intel Corporation (NASDAQ:INTC)-based CPUs with custom ARM processors is a modest headwind to the chip giant, as Mac processors account for roughly 3.5% of Intel's sales, analyst Vivek Arya said in a note.

The analyst noted that support for Intel-based Macs will last for the foreseeable future.

Apple's plan to switch is a long-term negative but it is unlikely to be replicated in the remaining 90% of the PC market, given ARM-based PCs' struggle for establishing compatibility with the PC ecosystem dominated by x86-based applications, he said. 

Arya also feels adoption of new ARM-based PCs in late calendar year 2020 and the first-half of 2021 could be slow, as users wait for Apple to fix unforeseen compatibility issues.

Intel's transition to a data-centric focused firm, with data center now accounting for over 50% of total sales, can help it offset any long-term PC headwinds, he said. 

"We also expect Apple to continue to be a strong customer for INTC-based x86 servers (higher ASP/margins)." 

New Use Cases For Apple's U1 Chips: The U1 chip, incorporating ultra wideband technology, which allows transmission of data at low power, is likely to make an entry into the auto applications in a big way, Arya said.

The analyst also sees other long-term use cases such as:

• car acting as a key for entry to secure locations
• precise navigation of indoor parking lots
• improved in-car safety
• remote-controlled parking

The analyst said he expects UWB to enhance industrial applications such as asset tracking and health care and consumer applications such as mobile payments, connected home and AR/VR. 

The development of the UWB market will benefit NXP Semiconductors NV (NASDAQ:NXPI) and Qorvo Inc (NASDAQ:QRVO), Arya said. 

Other Beneficiaries

EDA Players: Arya expects electronic design automation players such as Synopsys, Inc. (NASDAQ:SNPS) and Cadence Design Systems Inc (NASDAQ:CDNS) to benefit as EDA tools become more critical to systems companies.

An Intel Rival: Advanced Micro Devices, Inc. (NASDAQ:AMD) is an indirect beneficiary, as the market perceives Apple's switch to internal chips for Macs as signaling dissatisfaction with Intel's technological progression, the analyst said. 

The PHLX Semiconductor Sector (NASDAQ:SOX) ended Tuesday's session up 0.22% at $1,987.73.
