The Differences between x86, ARM, and RISC-V Explained

TLDRA comprehensive summary of the differences between x86, ARM, and RISC-V architectures in terms of instruction sets, power consumption, security, virtualization, and more.

Key insights

🔄The differences between x86, ARM, and RISC-V architectures are subtle and relate to memory addressing, branch execution, exception handling, and more.

🔐All three architectures offer security features such as Intel's SGX, ARM's TrustZone, and RISC-V's Multi-Zone Security.

🖥️While x86 and ARM support I/O virtualization, RISC-V is working towards implementing it.

💡RISC-V's open-source nature allows for collaboration and security audits, providing a potential advantage in vulnerability detection and improvement.

📚RISC-V's instruction set architecture (ISA) is published, allowing chip manufacturers to produce CPUs based on it without licensing fees.
