What Are Kunpeng and x86 CPU Architectures?

ECS supports the following architectures:

  • x86 architecture

    The x86 architecture uses the complex instruction set computer (CISC). CISC is a computer architecture in which single instructions can execute several low-level operations. There are a large number of instructions, and each of them has different lengths. CISC processors take longer time to execute instructions because they have more complex instructions.

  • Kunpeng architecture

    The Kunpeng architecture uses the reduced instruction set computer (RISC). RISC a microprocessor architecture with a simple collection and highly customized set of instructions. It is built to minimize the instruction execution time by optimizing and limiting the number of instructions.

    The Kunpeng architecture provides a better balance between performance and power consumption than the x86 architecture.
