Performance - Xeon E5 v3 vs v4 processor

You're looking at the wrong benchmarks. Your first link is to a single v4 CPU, while your second link is for dual CPU, i.e. two v3 CPUs. Notice the [Dual CPU] in the name, and also the cpuCount=2 in the URL.

A single v3 is only ~6000 on PassMark.

And here's the correct PassMark comparison, where the v4 rates higher on overall performance but lower single-thread performance owing to the lower per-core clock speeds. Whether this is beneficial will depend on your use-case.

I was going to purchase an E5-2609v4 CPU for a new server - but then noticed that according to Passmark tests it has a significantly lower benchmark at 6973 then the V3 version at 9885 - but I can't understand why this is - can anyone advise ?

Here is a link to the Intel Ark comparison - which shows that the v3 is 1.5 years older, has fewer cores which are slightly faster (1.9 as opposed to 1.7). I would have thought that Intel would have made incremental improvements for the same model CPU with a different version number, but this seems not to be the case ? As someone who will never need more then 768GIGS of RAM in the server, is there any reason I should buy the newer CPU at the same price?

  I always pause for a moment of silence when someone says, I'll never need more than X amount of memory...

  You're comparing a single v4 to dual v3...

  @Twisty - I did say "In this server".

  @davidgo I'm only joking. Unlike Bill Gates you didn't make a universal declaration meant to apply to all people for all time.
