Does the Neoverse core have hyperthreading? I know that vCPU threads on the major cloud providers are hyperthreads instead of real hardware cores.

- _msw_ 7y agoDisclosure: I work for AWS on EC2 infrastructure (among other things) No, the Graviton and Graviton2 processors do not have SMT. Each vCPU (or logical processor, for a bare metal instance) is a core.

From https://aws.amazon.com/ec2/instance-types/ https://aws.amazon.com/ec2/instance-types/ "Each vCPU is a thread of either an Intel Xeon core or an AMD EPYC core, except for A1 instances... Each vCPU on A1 instances is a core of an AWS Graviton Processor."
