I’m currently on a desktop sandybridge i7-2600. 3.4Ghz 4 cores/8 threads … so not really comparable . With a “normal” set of workloads, I see 20-30% base cpu utilization with spikes up from there.
I know on the desktop side, IPC gains have been pretty minimal with focus being mostly on efficiency. I don’t really have a good feel of how that translates on the mobile side. I also don’t keep up with the low-power mobile chips since I tend to deal mostly with tower/mobile workstations with the more powerful chips for my users. On an older ivy bridge laptop (with upgraded ram & ssd), I remember virtualization performance not being terrible (not sure which processor; probably the i5-2430M)
I was hoping someone in the community had experience running VMs on a U-series processor vs a Y-series.
