If the point isn't x86 but rather running Linux then look at IBM's zSeries servers. You can have up to 54 IFLs with each IFL equivalent in horsepower to between 10 and 30 x86 cores.

zSeries run zLinux with the best virtualization software, zVM, you can find anywhere. To find out more about Oracle on zLinux contact
