Intel Atom 2750 vs 2758



  • Hello all,

    As I've been digging around even more for a solid, near-future proof (because eventually, everything needs to be updated), motherboard/CPU for my build, I came across the new series of Intel Atom processors.  Supermicro makes some awesome-looking boards for the 2750 and 2758.

    They both have the same specs it seems (IPMI, 4 GbE Intel LAN, etc), with the obvious exception of the CPU.  From what I can see, the only significant difference between the two is that the 2750 (ARK) has a Turbo-boost mode, while the 2758 (ARK) has Intel's Quick Assist.

    Which would be a better fit for a pfSense box?  Would the added speed of Turbo Boost be more helpful, or would Quick Assist?  I don't know much about Quick Assist or if pfSense is even designed to be able to take advantage of it…I'm curious what insight the community might have.



  • After digging around a bit more, I found this thread, and it links to a passing statement that pfSense hasn't implemented QuickAssist yet.  Is that a planned feature of 2.2?  I've seen in a few places that AES-NI is supposed to have better support in 2.2…

    Also, when is 2.2 slated for release?

    2.2 is still in alpha. It was originally guessed to be June/July, but that's not going to happen. In general, they say "It's done when it's done". Assuming 1-2 months of testing after beta starts, don't expect sooner than near end of year.



  • Long term, the C2758 is the better choice since Rangeley was designed for networking devices.  There will eventually be support in FreeBSD & pfSense, you'll just need to wait a bit.



  • I was certainly leaning towards the C2758.  I've heard similar things about Rangeley in other places as well.

    So, I understand that FreeBSD and pfSense are always lagging behind on the latest and greatest hardware features, but would one of those Supermicro boards at least run pfSense, or is the hardware too new that it wouldn't run at all?

    Also, I read somewhere that a Marvel controller is used in these Supermicro Atom boards to help with the Quad GbE LAN ports.  Would that be an issue?

    Obviously, I'm hoping that the boards would at least run pfSense, and then just become more awesome as pfSense matures even more.

    I've got a SuperMicro C2758 at home and it works fine.  The NICs are Intel i354 with a Marvell PHY.
