I am looking to build a couple of new servers that will host OpenVZ and KVM virtual machines. As our experience shows, usually disk IO wins over processor performance in the long run, so there is no point in buying Xeon or Opteron grade hardware for us at 3-4x the price per server, we are better off by assembling more cheap nodes.
Currently there are two contenders for these new nodes:
AMD version
880G+SB850 motherboard, 16GB DDR3 RAM, PCIe RAID
Phenom II X6 hexa-core processor @ 3-3.2 GHz (1075T or 1090T)
Intel version
H67 motherboard, 16GB DDR3 RAM, PCIe RAID
Core i5 2x00 quad core processor @ 3.1-3.3 GHz (i5 2400 or 2500)
Since I was unable to find any meaningful comparison benchmarks between the two, I'm asking for advice: given the typical VPS workload (mainly OpenVZ LAMP servers and some KVM machines), which one would be the better choice?
I'm also interested in any comparison benchmarks showcasing CPU or IO performance regarding these two architectures that others have seen.
