I have two linodes. Both are 4 cores with 8GB RAM. I see different CPUs on both the linodes. I use one for production and one for test. Below is the CPU information I see. Please advise which one should I retain and use it for production. Which CPU is better?

Linode one:

  • Do you have these as bare metal machines? Or are they virtual machines where you share the CPU with other instances? If the latter, we can't possibly answer without knowing, for example, how many cores your instance is allowed to use. – David Schwartz Dec 22 '18 at 17:36
  • These are virtual machines. My plan has 4 cores. – Zoya Dec 22 '18 at 17:38
  • So you asked the wrong question. You don't want to know which is the better CPU, you want to know which CPU has faster cores. (If one has twice as many cores as the other, but the other has 15% faster cores, you want the one with the faster cores, not the one with twice as many cores.) – David Schwartz Dec 22 '18 at 17:40
  • You are correct. Both run Magento 2 with 200 visitors per day. 1000 SKUs – Zoya Dec 22 '18 at 17:41

The Xeon Gold 6148 has much faster cores than the E5-2680v2, primarily because it is four years newer. So that's the one you want. It also has twice as many cores, but that doesn't help you.

  • Thanks for the advice. So Xeon Gold is better for Magento 2 with 200 visitors per day. 1000 SKUs. Can you please confirm? – Zoya Dec 22 '18 at 17:44
  • The CPU is better for that task if you are limited to four cores on it. However, I can imagine theoretical cases where the other would be better. For example, say the Xeon Gold has lots of other customers on it who are using lots of memory bandwidth and the E5-2680v2 is idle so all the memory bandwidth is yours. But judging just from the CPUs and the fact that you have four cores, yes, the Xeon Gold would be better for almost any application. (I'm also assuming both physical machines are sensibly configured, for example, all memory channels populated.) – David Schwartz Dec 22 '18 at 17:47
