which would be a better cpu a Pentium N3700 or a Celeron N3150?

[BirdDad]

they both dissipate the same amount of Watts and seem almost the same.
They both have AES-NI

I plan to have 150Mbps cable connection real soon and want to be ready for it. So Pentium or Celeron? which do I need? It will be for openVPN with PIA on a pfSense box.

 

[BirdDad]

they are both quad core and seem about the same except for the Pentium's higher burst clock speed.
Thanks

The Pentium looks a bit better. Much higher burst speed. Better graphics.

the graphics don't interest me. What interests me is the computational abilities of the chips, which one is better for encrypting/decrypting a connection on the fly?
AES256,SHA256, and RSA4096?

 

[LTC8K6]

They are both Braswell chips with identical capabilities as far as I can see.

The Pentium should be faster with it's much higher burst frequency of 2.4Ghz.

You never know, you might need the IGP at some point.

The biggest difference I see between the two is the amount of excecution units in the igp (12 vs 16). The extra 300 MHz will probably amount to somewhere between 10-16% performance difference.

If the price difference is significant, go with the Celeron.

Because Braswell boards are not yet widely deployed, I suspect you will not find direct, authoritative guidance. However the Silvermont architecture has been around a while and Braswell is almost the same CPU architecture with a process shrink. Go nuts with Google searching for PFSense and J1800, for example, to get a sense of what to expect. I read some of the posts to suggest that a J1800 is generally good for 1 GbE WAN speeds so I would be comfortable with a Celeron N3000 (the really slow dual core you did not ask about) for your 0.15 GbE WAN connection. Iptables, however branded, is what PFSense is built around and it is a notoriously non CPU intensive kernel feature. It might not hurt to repost the question on a dedicated PFSense forum for greater certainty.

I do not like the motherboard you did not specify because it either features an onboard Realtek NIC or is ungodly expensive with onboard Intel NIC's and a power sucking BMC (Supermicro). Double check to verify that the onboard NIC is supported in PFSense as this has sometimes been a problem in the past. BSD and it's derivative distributions generally value Intel NIC's highly. Your unspecified motherboard may feature only a single PCIe slot. Consider a, perhaps used, Intel PRO/1000 PT Dual Port Server Adapter.

Do not get overexcited by TDP specifications. Intel shares a chassis thermal solution between several processors so they throw a bunch of different processors into an identical TDP rating. To date, I have not found a solid, apples to apples comparison of power requirements for different Braswell processors.

I bought the Pentium N3700 and it is much faster.
