It's exactly what Ryzen needs. Biggest drawback with Ryzen at the moment is the much lower max frequency compared to Kaby/Coffee.

Depends on the clocks it hits.
Intel got a lot of flack for making meagre gains. If Ryzen 2/+ whatever it's called is the same, in the name of neutrality, I'd expect the same response.
Zen+ is expected to bring some actual architecture improvements and tad more frequenzy. Its also highly nothworthy Intel sold PREMIUM 4 CORE parts in 2017, they could given you more cores if they wanted, but they only wanted to be a cashgrab. So as expected, there might be some pushback at times like those.

Even if it is just was a frequency hike, which it isnt, it would be worth it as thats the big drawback to the first gen.
4.4 or 4.5 ghz with 5% ipc improvement would be great.

I would rather they worked on improving the inter-CCX communication and the latency of the current DDR4 controller,which seems a bit high.
Soldato
I would imagine that the memory controller will be one of the things they've worked on.
Not long til we can find out!

That's where I expect most architectural improvements to be.
Doing more wide spread changes to CPU's internal design needs lots of R&D resources and it's not like AMD has excess of resources.
(Zen2 with new manufacturing node needs lots of R&D to keep it in schedule)
So for Zen+ IPC improvements are likely tweaking of some bottle necks and such.

Intel got flack for making 3.5% increments to their CPU's, granted the step up from Devils Canyon to Skylake was a lot more than that and pretty good but Sandy > Ivy > Haswell > Devils Canyon | Skylake > KabyLake the flack was well deserved.

It isn't that great still relative to what they were saying though hey

If you take "actual" figures out of the equation and look at what AMD have kind of hinted at previously (referencing low hanging fruit and 10%'s). AMD will be making another big wave in the CPU market purely for the fact that an upgrade will make more than a 5% increase. It should be raising a lot of questions of Intel as to why they dripped out the improvements an kept the core count so low for so long.

No, it never is.
As a collective we don't really care, we never have, we just want AMD to be competitive so we can buy more Intel stuff.
And that's why Intel don't care.
This is not me trying to bait you at all but what would you define as a meagre gain? What have the actual total gains been for Intel for their last 4 chips as a comparison?
I don't believe AMD have made a definitive announcement but from their graph and the foundry announcement they are suggesting a 8-12% improvement. Anything north of that is more or less hype train hope. I know we are hoping for a 5%+ IPC gain and a 10%+ clock improvement for a 15% uplift, but AMD have not said that.
I would be pointing some flack at them if there is less than a 7% improvement as they were clearly indicating that level or more.
I would love to have an internet Flakometer -
<6% WTF and you though Intel was bad?
7%-8% C+ It is a pass, but barely.
9%-11% Awesome - Intel looking hard to justify right now.
12%-15% Epic win, the hype delivered.
15%+ The internet explodes.

10% makes it hard to justify the 8700k over AMDs stuff, anything like 15% and its impossible to justify Intel stuff at all until they spurt out something else later in the year.
Soldato
AMD could quite easily get a 10% improvement from clockspeed alone on the new process.
The average OC for a Ryzen is ~3.8GHz, so if the new chips can do 4.2GHz without much hassle then then that's your 10% uplift without even tweaking anything under the hood...

Mid march I think it is. 18-23 rings a bell without checking properly.

AMD are paper launching Ryzen 2 at GDC 2018, 19 to 23 March.

Clockspeed is not the whole ballgame though. If a processor design does more processes at a lower clock then it is better IMO.
Soldato
No, but it is probably the easiest way of improving performance without huge R&D costs and is generally what is expected from a smaller fab process.
I don't expect there to be huge architectural differences between Ryzen and the refresh, just a few easy wins that tick up IPC a few points, with the bulk of the performance improvements coming from using a process node that is designed for higher clocks rather than low power.
My only issue with this is that, however good this might be (or not), are there not rumours saying that the 2019 reiteration, Zen 2, is going to be the game changer, which makes me want to wait to see what it could be regardless.
I know the logic behind not waiting for the latest thing, as you'll in theory always be waiting...but I don't mind waiting for a bigger change instead of the usual 10% or whatever.
