Intel Corp (INTC  ) is facing a crucial struggle for survival amid fierce competition in the semiconductor industry.

The once-dominant company now confronts challenges from various rivals, including Qualcomm Inc (QCOM  ), Nvidia Corp (NVDA  ), Advanced Micro Devices, Inc (AMD  ), Amlogic, and MediaTek, endangering the iconic "Intel Inside" brand on PCs.

This shift results from decades of ARM Holdings Plc's (ARM  ) growth in the mobile processor market, which Intel failed to penetrate effectively, the Wall Street Journal reports.

Apple Inc (AAPL  ) pioneered ARM-based processors in desktop computers, gaining a significant advantage over Intel and others in chip design focused on energy efficiency.

The move has influenced other major players like Alphabet Inc (GOOG  ) (GOOGL  ) Google, Qualcomm, and Amazon.Com Inc (AMZN  ) to design custom chips based on ARM's architecture, primarily manufactured by Samsung Electronics Co (SSNLF  ) and Taiwan Semiconductor Manufacturing Co (TSM  ).

Intel's market share faces a threat as Apple moves away from Intel chips, and Google's Chromebooks and Microsoft Corp's (MSFT  ) Windows devices increasingly adopt non-Intel processors.

Apple's market share in desktops and notebooks has risen significantly, intensifying the competition.

Microsoft, once a close ally in the "Wintel" partnership, is distancing itself from Intel. Microsoft's focus on cloud-based Windows experiences and ARM-based data center chips signifies a significant shift.

Amazon's cloud-streamed Windows devices and Qualcomm's ARM-based chips for notebooks further pressure Intel.

Despite these challenges, Intel remains a formidable competitor, planning new chip generations and aiming to match TSMC's manufacturing technology by 2025.

Price Action: INTC shares traded lower by 0.66% at $43.45 premarket on the last check Monday.
