While Intel Thunder Bay sparked rumors years ago as potentially being a mix of Intel x86 cores and Movidius VPU cores, although the Linux patches put it as ARM cores paired with the Movidius VPU, Thunder Bay is no more. As I wrote back in March, Intel Linux engineers have acknowledged Thunder Bay is cancelled and there are no end-customers/users so they are going ahead and removing the Linux support...

Recently I noticed out-of-the-box on Ubuntu Linux the performance of Intel Xeon Scalable "Sapphire Rapids" processors was much improved for some workloads compared to tests done just weeks ago on the same Sapphire Rapids server. It ended up being an issue coming full-circle and ultimately boils down to one line of code added within the Linux kernel.
