At my work we are researching a new Server to purchase and we are looking a a Dell R730 server. We have a quote from last year and this year. The processors for both quotes are listed below.
2016: Intel Xeon E5-2660 v3 2.6 Ghz, 25M Cache, 9.60GT/s QPI, Turbo, HT, 10C/20T (105W) Max Mem 2133Mhz (338-BFFG).
Upgrade to 2 Intel Xeon E5-2660 V3 2.6Ghz… (374-BBGN)
2017: Intel Xeon E5-2660 v4 2.0GHz,35M Cache,9.60GT/s QPI,Turbo,HT,14C/28T (105W) Max Mem 2400MHz
My question is, how can we tell which of the 2 processors provides better performance? Are there other factors to include as well such as system board?
A brief summary is as follows:
2016 - 10 cores per socket
2017 = 14 cores per socket
2016 - Version 3 with 2.6 Ghz
2017 - Version 4 with 2.0 Ghz
In the past we have been burned by purchasing new ESXi hosts that performed much slower with our applications than older models. For example a Dell T710 with 6 cores per socket and 2.8 Ghz out performs an HP ProLiant Gen9 with 8 cores per socket and 2.6 Ghz. I do not wish to purchase a server that will provide lower performance than the Dell T710 (6 yers old server).
How can we judge how the processors or how the server will perform compared to another server?
