AMD - Zen chitchat

[Terbinator]

Annoying it is later in the day but to be expected.

Do we think these are already in the hands of reviewers and results will go live tonight or tomorrow?

If reviewers have them, none of them have leaked anything yet which is highly unusual.
CPU do not really have drivers to deny OEMs the possibility of leaks like with the recent Nvidia Amphere launch.
The BIOS microcodes cannot be used like that as there is just too much testing to be done.

X470/B450 official BIOS for Zen 3 support comes in Mid-Nov

And who is that guy?

Zen3 capable BIOSes for B450/X470 won't be out until next year:

Interesting comment from Charlie here that the IO controller on 5000 series is identical to the 3000 series, only the compute chiplets have changed.

I suspect Zen3 is costing AMD less to make than Zen2 cost them last year!

lol, yeah even with those compute chiplets on a new process it is unlikely to be any more.

oh well, back to pricing up possible 3000 series upgrades...

hmmm, I understood zen 2 and zen 3 were on the same 7nm process?

AIUI, they are both on 7nm, but not the same 7nm process. Sort of a 7nm++.

But not with EUV yet, which should make them cheaper.

Thanks for the explaining it.. cheaper is what im waiting for.

I thought Zen 3 was meant to be using N7+ that uses EUV, perhaps I'm reading it wrong though.

On Investor's Day in May 2017 Jim Anderson, AMD Senior Vice President, confirmed that Zen 3 is set to utilize 7nm+ process.

The N7+ node is TSMC's first process technology to adopt EUV lithography.

Have i mistaken/mixed up 7nm+ with N7P and/or N7+?

EDIT: No, yes. I looked it up and found Anandtech clarified it, you're right and I'm wrong.

Because AMD labeled those as 7nm+, when TSMC called its version of 7nm with EUV to be N7+, one of the obvious assumptions that people have made is that where AMD wrote 7nm+, it was to be on the N7+ process. We have since learned that this is not entirely correct.

In order to avoid confusion, AMD is dropping the ‘+’ from its roadmaps. In speaking with AMD, the company confirmed that its next generations of 7nm products are likely to use process enhancements and the best high-performance libraries for the target market, however it is not explicity stating whether this would be N7P or N7+, just that it will be ‘better’ than the base N7 used in its first 7nm line.

I though they had confirmed that what they meant by have said is "7nm +" it being a slight refinement which was already used for the 3000 series XT models.
From the AT launch event coverage:

On process node technology, AMD clarified that these processors are using the same 7nm process that the company has contracted from TSMC as it did with the Ryzen 3000XT processors. Users may remember that AMD and TSMC were able to eke some extra efficiency from the base 7nm process, which was productized in the 3000XT family that launched mid-cycle.

I guess they could have claimed some kind of customisation like Nvidia did with Samsung's 8nm, but it would have been marketing waffle.

Chinese sellers have made a motherboard which has the original XBox One SOC on it:

Apparently its under £100.

Does this mean the 5950x is actually slower than the 3950x in multi threaded tasks?
