Are there recent performance gains in virtualization by newer CPU generations?

Hello together,

I am using a workstation with Westmere Xeon CPUs and the performance I get in Virtual Box is a little bit disappointing. I have a Notebook at work with an i7-8550U at work which performs way better in terms of “smoothness” and general performance inside VMs.
Were there any important changes in CPUs/CPU-extensions in the last generations that made virtualization faster?

Looking forward for your answers
