Judge casts doubt on RISC-V viability in Qualcomm v Arm case

During proceedings in the ongoing legal dispute between Qualcomm and Arm, a Delaware federal judge directly questioned the practicality of RISC-V CPU architecture, stating it is not currently usable at scale. The judge expressed the view that only Arm and Intel’s x86 architectures are viable options for the industry today. This remark came as Arm argued it faces competitive pressures from RISC-V, which the judge dismissed as not an immediate contender.

• Qualcomm and Arm are in a licensing dispute in Delaware court
• Judge stated RISC-V is not currently practical for use
• Arm maintains it faces competition from RISC-V and x86
• Qualcomm alleges Arm withheld key technical support
• The court's view may affect industry perceptions of RISC-V
