Speaking of compatibility, is it safe to assume if i got parts for the new AMD cpu that comes out in NOV, the 3950X, that they will work out of the box when i get the CPU? Like i have all the parts pretty much picked out for it..but hesitant to get motherboard.
As in going from a Zen to Zen+ required a Zen to flash. If the board supports one Zen+ it had some level of basic support for all Zen+.
The 570 is designed around Zen 2, so it should have basic support for all Zen 2, including the 16 core.
I can't think of a time where I could run one CPU in a generation but not another. It may need an update to correctly identify a CPU but generally that's not even an issue.
Oh that thing, guess it depends on which board you get. Some allow you to do that, some don't. But if you're waiting just for the cpu I'd wait, they'll probably get cheaper by a bit.
According to other sites the 3500/3500x chips are 6C6T chips which is a change from previous gens being 4c8t chips. The 3500x seems to be a 3600 without SMT from the specs I've been able to find. Sad that I had to search for articles on other sites to find the 6C6T detail as that's rather important.
"6C6T chips which is a change from previous gens being 4c8t chips" That is a weird way to phrase that. Previously we had 4C/4T, 4C/8T and 6C/12T CPUs from AMD in the Ryzen lineup (plus others of course). Now we also have 6C/6T. So we've had non-SMT chips before, just not at 6 cores. I'd rather have 6 real cores than 8 threads, personally. :) Will have to see how much these cost, might pick one up for my secondary build. That is, if the leaks are accurate.
I wonder if the HP Pavilion in question has a chipset cooling fan. Big OEMs are usually reluctant to pick up parts that have potential warranty replacement risks so if anyone can keep one of those new, blistering hot chipsets cool with something passive, it's probably a company like HP.
Price...and e-peen size. Mainly e-peen size though as we all know that the letter X makes it feel bigger when you put it in the socket or post a photo of it to show it off to random people on Reddit.
According to other comments, 3500X is 6C6T while 3600 is 6C12T. I had the same question when I read the article as the table shows everything as equal.
Pretty large difference in MT performance then. Previous-gen Ryzen had up to +50% on MT performance with SMT, with ST improvements in Zen 2 it is probably not as large as there are fewer underutilized resources in ST per core, but still should be noticeable, maybe up +30%?
Other sources are indicating that the 3500 will have half the L3 size of the 3500X. This may be a cost recovery effort by finding a use for CCDs that have defective L3 cells. Given the lower thread count of the 3500/3500x, the halving of the L3 may not make that big of a difference to overall performance. Also, since one of the effects of SMT is to hide memory access latency in high MT scenarios, not having that enabled on these chips may exacerbate the issues that AMD has with overall RAM access latency with respect to Intel, meaning that, the L3 size change may instead be a bigger performance issue, and that DRAM performance tuning and overclocking may play a much larger role in the performance of these chips than the 3600s.
It'll be interesting to see the benchmarks of the 3500/3500x as compared to the 3600 and the 2600/2600x. I suspect that the 2600X will be priced very similarly, and, when carefully tuned, will likely be faster than the 3500 in most cases, and likely only trail the 3500x in highly single threaded tasks.

It'll work on all x570 mobos, just need bios update. They're all made to support 16 core cpus.JoeyJoJo123 - Tuesday, September 24, 2019 - link
Yes, but I believe his question relates to whether it'll even be possible to do the initial bios flashback without an "out-of-the-box" compatible CPU.0ldman79 - Tuesday, September 24, 2019 - link
Typically that's only a generational issue.As in going from a Zen to Zen+ required a Zen to flash.
If the board supports one Zen+ it had some level of basic support for all Zen+.

x570 should support OUT THE BOXextide - Tuesday, September 24, 2019 - link
Go look at the support page for the mobo you want -- it might already be listed. If not .. well I am not exactly sure.kpb321 - Tuesday, September 24, 2019 - link

Yes search for info that was available already before this was posted.TheinsanegamerN - Tuesday, September 24, 2019 - link
Given the chips are unanounced, and the specs unconfirmed by AMD at this point, would you prefer that Anandtech star posting rumors whenever possible?This isnt WCCFtech. The listings do not report on core/thread count, so Anandtech did not inject the suspected counts into their report.
0ldman79 - Tuesday, September 24, 2019 - link
^^This.Anandtech posted what they could somewhat confirm, not speculation.

A quick check on HP's website does wonders: under "chipset" it lists "AMD Promontory B550A"peevee - Tuesday, September 24, 2019 - link
So what is the diff between 3500x and 3600?PeachNCream - Tuesday, September 24, 2019 - link
