Best CPU for running ESX on an HP DL380 G9

Hi All,

I'm looking to buy two new HP DL380 G9's to run ESX server.  Due to licensing we are only buying a single CPU.

Here are the options I had in mind;

HP DL380 Gen9 Intel® Xeon® E5-2698v3 (2.3GHz/16-core/40MB/135W)
HP DL380 Gen9 Intel® Xeon® E5-2697v3 (2.6GHz/14-core/35MB/145W)

There is hardly any difference in price, around £2500 (per CPU).

Which is best (or is there a better CPU around that price point)

Many thanks

I would highly recommend the use of Dual Processors, but this will depend on the number of VMs, and workload.

I would opt for more Cores.

More Cores, More VMs, e.g. more virtual sockets available for VMs.

I'm replacing two servers that are only licensed for a single CPU, so it'll really bump up the price to add the second socket. I also like the option to double the horse power later if I need it.

Do you have any thoughts on the two CPU'S above.

One is 300mhz quicker, the other has two more cores.

Yes, I stated, purchase the one with more cores, more VMs per box!

I would go for more cores on a VM host. Having said that, would be almost impossible to detect any difference between those two in any sort of real-world benchmarks.

Thanks for the feedback.  I was hoping to compare the benefits of a higher clock speed vs more cores.
