I am not aware of any Zen3 ES let alone Vermeer ES thus far. In Contrast, Zen2 ES were common almost 8 months before launch.
I was expecting it last year in July when I would have bought it, alas it is most definitely not early at 10 months and counting since then.
I think a friend of mine with one 300 series MSI Tomahawk got from a pretty bios at release and now the newer one according to him is super ugly.
I think they are overdue to make some headway in the NUC/SFF market to be honest - once they are done plying Renoir to laptop OEM's they should switch to putting the thumb tacks on Zotac and co to get the ball rolling.
Wow, even 5-6 quarters from tapeout to mass production is a really long time, especially as mass production (at least for consumer parts) generally starts at least a quarter before launch. That has to mean mass production of the CCDs actually starts earlier but they are taking their time to build up stocks and bin chips while selling desktop chips earlier IMO. Otherwise that lead time is absolutely crazy.I am not aware of any Zen3 ES let alone Vermeer ES thus far. In Contrast, Zen2 ES were common almost 8 months before launch.
They stated that they have been sampling since Q4 last year. But till now not even a part number anywhere. Nothing.AMD Zen 2: Engineering Sample in Benchmark-Datenbank zeigt doppelten L3-Cache
In der Benchmark-Datenbank von Sisoftware Sandra ist offenbar ein Zen-2-Engineering-Sample von AMD aufgetaucht. Die CPU 2S1404E2VJUG5_20/14_N entspreche einem Rome-Prozessor mit 64 Kernen. Der L3-Cache wird mit insgesamt 256 MiByte ausgegeben, was die spekulierte Verdoppelung untermauert. Die...www.pcgameshardware.de
If they are this quiet it must be very good. Can't imagine otherwise. Looking at the 3100 vs 3300X comparison, just having a unified cache raised "IPC" considerably. Optimize some DRAM latency. Just like that, IPC will improve without touching the core.
From HarwardeNumber3rs testing, increasing frequency does not do much for Zen2, so I guess that was the reason they did not bother much with it. In fact would have been negative PR with higher frequency.

I still believe they will be on track for late Q3 this year at the latest just like they stated on their slide from last Nov (Also confirmed from the NERSC PR). Probably earlier for Desktop.
Otherwise it is going to be almost TWO years from tapeout to Launch and one year from sampling to launch. That is nuts. That is way too long.
I would love that too - those chips would be perfect for those applications. There was that tweet from Ian Cutress (I think) though about SFF PC OEMs being more or less strong-armed by Intel into having really, really slow development cycles for anything AMD-based (Ryzen 3000 mobile APU nuc-likes first arrived around new years, a full year after the chips launched). Wonder how much meat there is to that accusation. Certainly wouldn't surprise me.
I agree on that, though I would expect a September launch to mirror last year's with not quite a full lineup and availability stabilizing closer to Christmas. But anyhow, September is too late for desktop Renoir.
There is a good chance they are taking their sweet time since they want to spend more time on Zen 4 as well as not cannibalize their Zen 2 products too early. One needs to remember that the TTM pressure is based on what AMD years ago projected Intel being capable of launching now, and that turned out to be a constant stream of hot air so that pressure mostly dissipated.
There's also the issue of getting motherboards up to speed. The COVID related problems in China really killed production - it's pretty hard to continue development when there are no new boards coming out of production (from a firmware perspective). Where are Vermeer CPUs assembled? If China, getting enough ES samples could have been a problem. Anyway, all of this is occurring in a near vacuum of facts. Tech companies are so tight lipped nowadays that I find it a bit frustrating, personally.
I'm more inclined to think that Zotac do not even want to produce AMD based products - I believe they merely announce them to make themselves sound less like the obvious Intel/nVidia partisans that they have long since become, hoping that any AMD fans might tire of waiting for an AMD product from them and just buy Intel/nVidia anyway.
Not really, the new chiplet strategy meant that one single die was going to be in 3 different product lines (EPYC, TR, Ryzen), so they probably had to be very careful about testing and verification of that CCD + of course the separate IOD's associated with it.
But aren't these just rumors? Has AMD made any specific claim other than 'in 2020'?
All of AMD's CPUs are assembled in China by AMD/Tongfu JV. Additionally, they have a subsidiary in Penang, Malaysia.
I think as of now (the situation is fluidic) things are looking better in APAC (South Korea, Japan, China, Taiwan etc) and even our factories in China have also reopened since two weeks ago.
I am sure there is a surge in the interest for EPYC Rome recently. Last couple of weeks, there is a flood of PR announcements from Lenovo, HPE, ASUS, Gigabyte, Supermicro and what not about new EPYC offerings.
According to TSMC, much of the equipment is the same for the 7nm family (N7, N6, N7+, N7P) and the chips are actually produced in the same fabs. (Fab 12, Fab 14 and Fab 15 in Hsinchu Science Park, Tainan Science Park and Central Taiwan Science Park respectively).
One day they're can't sell them fast enough, the next day they can't make them fast enough. Gotta love the industry.
Enterprise and server hardware always goes through extremely intensive testing and verification, so I doubt that changes much between Zen 2 and Zen 3 - they are similar architectures on similar nodes, after all. Also, I don't think AMD can afford to wait a year and a half between taping out a design and starting mass production - the R&D costs at that point would be absolutely astronomical, and with nothing being mass produced, none of that would be recouped until 3-6 months later. Even with Zen 2 sales being very good, that is not the type of lead times you want on your products if you want to avoid financial issues.
It was also mentioned in AMD's earning call Q&A that there's a "strong" backlog for Rome, so that part's official.
Is that documentation already publicly available by chance? Know only of developer guides and tech docs.
Yes, look for tech docs mainly. You can go through all of them, but usually System Programming gives more hints about the processor capabilities. Media Extensions are also interesting
