Only c7a.48xlarge or (ideally) its c7a-48.metal equivalent instance. Otherwise you’ve got a CPU-stealing neighbor.

My understanding is that vCPUs are mapped to hyperthreads or (in this case) physical cores (note: not whole CPU packages). As some noted there’s shared L3 cache, but AFAIK this would not be “steal” as the kernel presents it.
