Pretty much what the title says, I was wondering, since I want to invest on self hosting applications and my raspberry pi 3 b+ can barely function. I don’t have enormous expectations, just docker containers, nextcloud, pihosted, jellyfin… Any further suggestions (regarding the hardware) will be much appreciated.
i3 are good enough for the things I wrote or should I got for i5/i7?
depends on how many services you plan on running, i think the i3 would be sufficient for what you listed, the i5 would give you room to grow.
the i7’s usually aren’t worth it for servers since they are just a clock speed increase.
Celeron would handle that (see my other reply)
In general, I’d say it’s good enough. i5 might have more cores if you need them, but then i7 only gets you slightly higher frequency, which may not be worth the price.
Check for the exact core configuration and cache size via Intel Ark first. More often than not i5 and i7 can have the same core configuration and cache size but difference base and boost frequencies.
