The interesting question becomes what the IPC of Zen 2 will be.
AMD claimed that they had major changes that they could utilize to improve Zen 2, perhaps in time to oppose an Intel 10nm Skylake shrink.
I'd be very interested to see everyone's thoughts on the type of IPC that we might see...
6 cores per CCX? So does that mean the follow on has 12 cores?
Then 24 for Threadripper 2 and 48 for Epyc 2?
I am wondering too about the clockspeeds on 7nm:

I meant when you run RAM in 2T, there is a performance penalty. OFten though, 2T means you can get faster clocks or tighter timings. The question is if the extra clocks/tight timings outweighs the 2T penalty.
But if it is looking like 2T is a liability rather than an asset, then it is 1T all...
Just a head's up everyone, it may be worth upgrading to Kernel 4.10 or newer for testing.

Anyways, you can use the Ubuntu Kernel Updater (works with Mint too as Mint is based on Ubuntu)...

Il y a bien des Ryzen 16C/32T axés HEDT prévus sur X399 dans 4/6 mois. Clocks ~2.4/2.8G. 2 dies MCM. 4 chan DDR4. Socket LGA SP3r2. ~150W.
16 core is 150W, not 180W...

Canard PC says 3.1 GHz base, 3.6 GHz turbo, 180W TDP.
That's not far from 3.2 GHz - only 100 MHz for the QS. Engineering samples are often a bit slower.
Thinking about your power consumption figures, do you think that the 32 core could run 180W at around 3.2 or 3.3 GHz? Ryzen seems to be uber efficient at the optimal clocks.

Has anyone tried ECC on Ryzen? Asrock's boards should support X370. No idea about the other vendors.
AIDA64 wasn't giving correct numbers for L2 and L3, I know, but they said that L1 and RAM were ok.
From what I understood, it was to be incorporated into the next version of AIDA64? Do you...
True, but the data was from Hardware.fr, which is a pretty solid source. In any event, the memory latency numbers, while an interpretation might be incorrect, the numbers themselves are not going to change.
I might have an answer for you.
Memory latency is 98 ns on Ryzen.

Let's think about this.
We get about 45ns or so within cores. We get 98ns or so within RAM. 45 ns (from within the...
On the X399 report. this was just Tweeted:

Canard PC maintains CPU-Z, so I'm thinking this rumor is legit.
Yeah that would be good.
The SMT performance drops we are seeing would disappear if that were to happen.
I'm thinking:
L4 cache
If they could get the clocks up to 14LPU, we're looking at a few hundred more MHz - very good if they want to go head to head with Skylake E (out in a few...
