CPU Architecture

Description

  • x86

    The x86 CPU architecture uses complex instruction set computing (CISC). Each instruction can be used to execute low-level hardware operations. The number of instructions is large, and the length of each instruction is different. Therefore, executing such an instruction is complex and time-consuming.

  • Kunpeng

    The Kunpeng CPU architecture uses reduced instruction set computing (RISC). RISC is a microprocessor that executes fewer types of computer instructions but at a higher speed than CISC. RISC simplifies the computer architecture and improves the running speed. Compared with the X86 CPU architecture, the Kunpeng CPU architecture has a more balanced performance and power consumption ratio.

    Kunpeng CPUs offer a high density, low power option that is more cost effective for heavy workloads.

FAQs

Can I Switch a Kunpeng ECS to an x86 ECS?

No. The CPU architectures of the two ECSs are different, making some binary file formats in the OSs used by the two ECSs different, so a Kunpeng ECS cannot be switched to an x86 ECS.

Can a Private Image Created from an x86 ECS Be Used to Create a Kunpeng ECS?

No. Some binary files in a private image created from an x86 ECS can run only on this ECS and cannot be used to create a Kunpeng ECS.

Can I Create a Kunpeng ECS Running Windows?

No, you cannot use Windows images to change the OS of a Kunpeng ECS either.
