I planning to upgrade one of my old harpertown based server to a new alternative but when I look at the comparison, this new one doesn't seem to be better at all, matter of fact if I look at the clock frequency it even seems to be worse:

http://ark.intel.com/compare/33082,64615

There is 6 years of difference between the two, would this comparison mean that I would actually get something worse for more money?

Bus Type FSB QPI System Bus 1333 MHz 6.4 GT/s

Well the bus type connecting the cpus seems to be the only advantage here and the new DDR3, DDR4? ram because the old 667mhz FB-DIMM heated up a lot.

This server is running 10 VMs (linux, windows, bsd). Would I get better performance or actually worse after the upgrade? Is that the new cpus clock speed (GHZ) lower means that it is actually slower than my old one was?

The power consumption is 80W for both, how can that be when the new one uses 32nm technology?

Thanks!

  • There is no comparison there. The new processor is _much_ faster in the real world. A less low-end processor, or a newer one, would be faster still. – Michael Hampton Aug 19 '15 at 18:10

Looking at the specs is only part of evaluating a new system. To do the job properly you have to benchmark the old and new systems under typical workloads. Only when you have done that can you make an informed decision.

  • Yes I didn't buy the Sandy yet that's why I asking here because maybe somebody did similar upgrade and noticed speed increase / slowdown compared to the old one. – juno83 Aug 19 '15 at 09:49

While Sandy Bridge is way faster than a similarly clocked Harpertown, you selected a very low-end Sandy: it has no Turbo, no HT, and its clock frequency is very low.

Here you can find some benchmark between two similarly clocked Harpertown and Nehalem system. As a rule of thumb, consider an equally clocked Sandy-Bridge system about 30% faster than a Nehalem one.

My suggestion is to go with a Sandy-Bridge enabled server, but with a model having Turbo Boost and HT at least.
