Processor Model vs Core Count vs Core Speed
I know it's a decade old question, and the answer is depends, but I still can't get my head around it. Especially on Lowendmarket where every drop of penny count.
My usage is for web / db server, nothing fancy. Just Nginx + mysql for Wordpress and NodeJS.
Let's look at the case
Intel Xeon E5645 12 cores, 24 threads @ 2.401GHz VS 2 x Dual Intel Xeon L5630 16 cores, 32 threads @ 2.13 GHz.
Intel Xeon E3-1265L v3 4 Cores, 8 Threads VS 2 x Intel Atom C2750 16 Cores, 16 Threads @ 2.4GHz
Intel i3-2130 2 cores, 4 threads @ 3.400GHz VS Intel Atom C2750 8 Cores, 8 Threads @ 2.4GHz
All of them have similar Price, but different cores count / speed and very different processor model.
Which of each case it will perform better and can handle more concurrent user / visitor ?
Does it always best to prioritize core count over everything else ? for a web and database server. Even tough it's just an atom. I mean 16 Cores @ 2.4 Ghz, isn't that bad. Also can the intel atom really beat the i3 in this regards ?
