That would depend on the type of CPU Linode is using. What the CPU's frequency is, the amount of cores, whether it has or does not have hyper-threading technology.

The hyper-threading technology is a pretty cheap way to add more virtual cores to your VPS's which is great. One thing is for sure and that is that Linode provides you 4 virtual cores and not 12 per VPS. But, that of course doesn't mean their CPU is better or worse. But, if you can run 6 cores at 3.8ghz, or 12 cores at 1.9ghz then I wouldn't worry too much about not having enough CPU power for your virtual private servers.
