Definition of ARM and x86 processors

Here’s a brief comparison between x86 and ARM architectures :

ArchitectureComplex Instruction Set Computing (CISC)Reduced Instruction Set Computing (RISC)
EndiannessLittle-endian or Big-endianUsually Little-endian
Power ConsumptionGenerally higher power consumptionGenerally lower power consumption
PerformanceTypically higher performance for desktops and serversOften more power-efficient, commonly used in mobile devices and embedded systems
Instruction SetLarger and more complex instruction setSimpler instruction set
Code DensityLower code density (larger executable size)Higher code density (smaller executable size)
ApplicationsDesktops, laptops, serversMobile devices, embedded systems, IoT
ManufacturersIntel, AMDARM Holdings, Qualcomm, MediaTek, Apple (for their custom ARM-based processors)
Compatibilityx86 binaries are not compatible with ARM processors, and vice versaSoftware needs to be compiled for the specific architecture
