AMD announces Navi GPUs, 3rd Gen Ryzen CPUs

[HEXUS]

12-core, 24-thread Ryzen 9 incoming!

First thread reply
Long awaited and nice to get past the rumour posts and disinformation.
Thank you for the morning update Hexus. Some staff and people must have stayed up and worked hard to see this happen.

Some personal observations:
3.8GHz base and 4.6GHz - 12 cores 24 threads - 70mb cache seems like a workstation or server ideal. I like it! Good luck for AMD with the 3900X units.

I would probably choose the [edit: 3700X is $329 rrp :/ below is under 16 threads. Can manage ~4.5 GHz I guess.] ... As the "a bunch of improvements culminate in an average 15 per cent IPC improvement over what we have seen before" statement (from AMD.) shows that if I can run 16 threads at 4.3 GHz or so that may be a value proposition.

My question for Hexus is - Will these chips work in an X470 motherboard? Particularly the MSI Gaming Plus X470.

I would probably choose the 3700 or 3600 assuming they were lower binned 3700x at some stage.

A bunch of X470 boards are certified for 3rd Gen. Manufacturers will update their respective lists, starting today.

At 499 for the 12 core 24 threads is a really good deal for Workstations.. and the cool thing is that we all know that there is a 16 core variant out there in the world but we wont see it until the next series like Ryzen 4000 or later and it will still be compatible with X series motherboards the high end of course... but i knew we wouldn't see Ryzen at 5ghz maybe if you will be able to get another 200mhz at the most so 4.7+ if lucky... and we still don't know the all core clock boost for long periods of time... but for rendering 500 bucks is still a REALLY GOOD DEAL compare to Intel

Yes I did post some silly speculation on 5+ghz 32 thread in a discussion a few days ago - sorry about this - reading too many iffy articles I guess. Curse of the 'net.

Another question for readers and perhaps Hexus - I have a B350 Gaming Plus from MSI too which has been really good after AGESA updates were deployed and perfectly good while it does have 1 or 2 PCI slots and 4 sata. Is this chipset series going to be Ryzen 3nnn compatible for us too? I saw a rumour that it may not (though it is 2nnn series compatible I believe).
I also have a smaller B450 board that I would expect over the next few months could be updated to a 3700(X) compatability status. It's an Asrock #B450M-HDV. I have a spare 2 series APU to do updates.

Why my rented flat is turning into a parts garage - I have no explanation so - good morning readers : ]

No 3600X listed for July? I guess that performance level is already catered for in the existing 2800X chips and they can use working core chiplets in the 12 core parts, but 6 cores is where I was expecting to buy. I guess that leaves me a choice, I could get a 2600X whilst they are cheap, or stump up for an 8 core Zen 2.

Edit:

Is this chipset series going to be Ryzen 3nnn compatible for us too? I saw a rumour that it may not (though it is 2nnn series compatible I believe).

Compatibility seems down to BIOS and power delivery rather than chipset. Some boards are dropping support for the old APUs like the A10-9800 to make BIOS space for the new CPU support, seems a decent trade. Cheaper boards may not handle the higher power requirement of a 12 core chip, but you probably wouldn't pair those together anyway.

[Millennium]

Thanks, DanceswithUnix (and nice to be in touch after some months!)

On your first point, I would wait for the 3600(x) part based on AMD stating a 15% potential IPC improvement [presumably over Zen 2!]. We would have to wait for ES or reliable MIPS tests - AMD is not as marketing led as their competitor might be them so I expect we could see a 10%+ average IPC improvement over the Zen 2 thread per thread. Worth waiting for most of us I think.

Thank you for your second answer and honestly I would not expect MSI to release a 2019 bios for my B350 board. Perhaps someone will make it work sometime in the future. 2 spare unused boards gives me pause. We shall see - perhaps Asus Gigabyte will update some high end B350 boards and that and some support email traffic might prod MSI into an update for their venerable B350 Plus boards.

I'll be eyeing up that 3700X.

[Tabbykatze]

This is the really important bit:

"...with Intel based on a more expensive platform - in both single- and multi-threaded tests while consuming a fair bit less power."

There's not that much difference in stock clocks, really looking forward to the independent reviews.

I wonder if there are any drawbacks associated with the dual chiplet layout of the 3900X? *If* the 3800X is a single chiplet design it might explain why they push that one as a gaming halo product instead. And I hope that they stick to a consistent layout for each model number - I don't want there to be a situation where reviewers get one layout but in retail it's a lucky dip...

Point well made, it could mean inter core access latencies may be different depending on chiplet layouts.

But that depends on howmuch inter core access really happens, it used tonhappen a lot on the Zen/+ series because of CCX based memory controller access which trashed memory latency sensitive applications.

But if they've homogenised how each individual core is accessed it won't matter if it's 1 core per 8 CCXes or 8 cores for 1. We'll know more once people like at STH and L1tech get their hands on.

It's likely R7 is just the marketing target for top end gaming that's all rather than capability limitations.

I may have just found my next motherboard, the ASUS PRO WS X570-ACE (https://www.asus.com/Motherboards/Pro-WS-X570-ACE/). ECC support, which is a must-have for me, is a headlining feature. Now to find out which Ryzen 3000 series processor to pair it with...

Update: Well, I may have been a bit too quick. Seems like this board is also actively cooled. That's really a no-go for me. Hopefully, a similar board comes along without active cooling.

You can put a 3k cpu into an old x370 or x470 mobo. Except you can't put a 1000 series cpu into a x570 mobo. This is the very thing I wanted to do. AMD pulled an Intel after all.

[smargh]

Oh myy!

I have a Xeon 6134 and was quite disappointed with full 6-channel memory speeds, so curious how well Rome will perform.

I can't see any indication that first gen cpus are not supported on 3rd gen boards. There is a stickler that 3rd gen CPUs will not be supported on 1st gen boards in most cases.
