The debate over whether ARM is faster than x86 hinges on various factors, including application type, power efficiency, and processing capabilities. While traditional benchmarks often favored x86 for raw performance, advancements in ARM technology have led to competitive performance levels, particularly in mobile devices.

What are the main differences between ARM and x86 architectures?

ARM (Advanced RISC Machine) utilizes a Reduced Instruction Set Computing (RISC) architecture, which emphasizes simplicity and energy efficiency. In contrast, x86 employs a Complex Instruction Set Computing (CISC) architecture, allowing it to execute more complex instructions per cycle. This fundamental difference impacts their respective performances across various applications.Architecture Comparison Chart
