Windows Server 2008 R2 Standard SP1 64-bit Note: The results in this article are likely notapplicable to NUMA systems with physical processors in multiple sockets, since these have very different memory, cache, and thread scheduling characteristics. Note: All cores run at 3.7GHz during multi-threaded benchmarks for single-threaded benchmarks, the core runs between 3.7 and 3.9GHz.Single Intel Core i7 4770K, 3.5GHz, 4 physical cores, 8 logical cores (when Hyper-Threading is enabled) Physical Hostĭesktop system where the CPU and motherboard were released in AD 2013: CPU VirtualBox warns if the guest is configured with more processors than there are physical cores on the hostĪs always, these results are only valid for my particular configuration and on my chosen benchmarks, including the assumptions that the physical host is idling while the single virtual machine is running flat out – do test with your own systems and tasks.
