Intel Pentium N4200 vs Intel Atom C2558 or something else

[Vaseer]

I am going to build new OPNsense firewall and currently I am choosing hardware.

Internet speed: I have fiber 300 Mb/s download and 100 Mb/s upload speed but in near future I am expecting to get 1G/1G connection.

I will be using Suricata, VPN, proxy and probably some other applications as well. For VPN I need to get reach 50-100 Mb/s upload and 50 Mb/s download speed with IPSec and ~20 Mb/s upload/download with OpenVPN (not simultaneously).

I am choosing between Intel Pentium N4200 and Intel Atom C2558, but I am open for suggestions.

Are Intel Pentium N4200 and/or Intel Atom C2558 powerfull enough for current (300M/100M) and possible future (1G/1G) internet speed? Can they provide desired VPN speeds?

Both are quad cores with AES, so would be suitable for your needs. The Pentium is a mobile CPU so likely more prone to power saving but it is more modern than the Atom (14nm vs 22nm). The Atom supports more RAM (64GB vs 8GB).

Since I have neither the line speed nor the hardware, I can only give you a best guess. My choice would be the Pentium.
