Here’s a brief comparison between x86 and ARM architectures :
| Feature | x86 | ARM | | --- | --- | --- | | **Architecture** | Complex Instruction Set Computing (CISC) | Reduced Instruction Set Computing (RISC) | | **Endianness** | Little-endian or Big-endian | Usually Little-endian | | **Power Consumption** | Generally higher power consumption | Generally lower power consumption | | **Performance** | Typically higher performance for desktops and servers | Often more power-efficient, commonly used in mobile devices and embedded systems | | **Instruction Set** | Larger and more complex instruction set | Simpler instruction set | | **Code Density** | Lower code density (larger executable size) | Higher code density (smaller executable size) | | **Applications** | Desktops, laptops, servers | Mobile devices, embedded systems, IoT | | **Manufacturers** | Intel, AMD | ARM Holdings, Qualcomm, MediaTek, Apple (for their custom ARM-based processors) | | **Compatibility** | x86 binaries are not compatible with ARM processors, and vice versa | Software needs to be compiled for the specific architecture | ARM and x86 processors
