Apologize if I shouldn't ask this here.

I want to acquire a VPS or a Dedicated. I read about VPS and Dedicated and the differences but I don't understand something...

Is a VPS with some resources (X CPU cores, Y RAM, Z Bandwidth etc) the SAME as a Dedicated with exactly the same resources (X CPU cores, Y RAM, Z Bandwidth etc)?

I saw VPSs are cheaper than Dedicated even with same resources. What is the difference? If there is a difference is it big (affecting the performance so much)?

Thank you very much!

In the best case, it will be of similar performance (with a slight performance impact due to the virt overhead). In the worst case with a bad provider, you end up in a "up to X" situation where the provider overcommits resources and if people start to use those resources, things get slow.

VPSs are cheaper because even a good provider can overcommit (selling more resources then he really has, because in reality, most servers idle most of the time) and also because there is a big overhead to run a physical server and it's much cheaper to run one powerful server that then runs a number of smaller VPSs instead of running the same number of physical servers.
