AMD Discloses Initial Zen 2 Details

Almost certainly. Zen 1 supported ECC on everything down to low-end consumer chips. It's unlikely but within the realm of possibility that ECC support will move up-market slightly with Zen 2 but is almost unthinkable that Zen 2 won't support it at an architectural level.

Is it going to support ECC memory?

All AMD processors have supported ECC for a very long time, its trivial to support it, Intel have just decided to gate it as a premium feature.

Sort of - they let mainboard vendors decide whether to support it or not, which means it can be a crapshoot. For example, MSI's been known in the past to kill ECC support with a BIOS update; some vendors have tested that you can use ECC RAM but won't enable any of the error correction (for example, Gigabyte say this in [1]: "non-ECC mode".)

Selfishly I really wish they would make it easier, because I'm in the market for a new personal-use storage machine and I've spent far too long researching all this crap but it's looking like I'll have much more certainty that it'll all just work if I buy a Xeon E3/E-2000 series and that's unfortunate.

64 cores with 128 threads. Hope that comes to threadripper. I love and for bringing back competition to the CPU market. We've bought a ton of amd machines in the last year, great bargains in our space.

I recall hearing that certain motherboard manufacturers were disabling ECC for their lower-end AMD boards.

Does anyone know if this was ever confirmed or not?

>On the security side, Zen 2 introduces in-silicon enhanced Spectre mitigations that were originally offered in firmware and software in Zen.

does intel have something comparable on their roadmap?
