Intel Processor Refresh in Spring - 100 MHz bumps
Earlier this week you've already read the funny news about a KFC edition, in the upcoming weeks more processors will be added into the lineup from Intel, they, however, all are refreshes mostly 100 MHz increase on the frequency. In the desktop segment, You've already seen the Intel Core i5-9400 / 9400F.
In retail you can already spot most of the new SKUs listed, for the desktop, processors in the Coffee Lake Refresh will be available as the Core i-9000 processors.
Similar to the Core i5-9400, most models will be a higher-clocked Coffee Lake, typically 100 MHz more clock. The naming is a little weirder though. If you look at the below overview the Celeron sticks to two cores and two threads, Pentium procs offers at least four of them (two cores + two threads) now going to 4 GHz (Pentium Gold 5260). This is an entry-level Pentium Gold G5260 model is already present in some European stores along with a prominent availability date on March 4th. It is not known which architecture the Pentium Gold G5260 is based on, but according to a current Intel roadmap, this should be Coffee Lake-R. With the Pentium Gold G5260, six additional models are planned: Pentium Gold G5420, Pentium Gold G5420T, Pentium Gold G5600T, Celeron G4950, Celeron G4930 and Celeron G4930T. Pentium models should come in combination with two processor cores and a total of four threads, while two processor cores and two triads are expected in Celeron.
It is expected that Intel will bring the entire range of new models to market in April. Some of the KF versions can already be found.

What people like you don't understand is that I don't want to buy a CPU for some theoretical future that may or may not come in 5 or 10 years. I buy a CPU for things that I do with a PC right now, and in 2019 or 2020 that still requires strong ST performance. By the time this changes we'll have had 3 new generations of CPUs.
As a developer myself, I can ensure you that such a change will not come over night, because there is a lot of fundamental limitations to multi-threading everything. Its extremely complex and in some cases requires fully re-thinking from scratch. As such, ST will still be an important factor for years to come, and people that try to talk that away are just blinding themselves.
People here asking for better ST performance dont understand, that 5.5ghz is about max where we have room to go. In next 5-7 years. St performance was an old way of doing things. Parallel processing/computing is a way forward. Right now ST prorgramming rules, because 4Cores was a norm just 2 years ago. Developers are slowly but steadily adjusting to more core count CPUs. Because of the hard 5.5ghz fall ahead of us. Even at 3nm manufacturing process. Only way to get more performance is to add cores and programs that are built to use multiple threads at same time. ST performance cheering is like cheering for the use of coal in the age of rocketfuel.

The big question for me around Zen 2 is not single thread performance or clocks. I think they are going to nail that.
the concern for me is Latency. going for a chiplet design can have some latency issues between the cores and the I/O. hopefully it will be good.
>60ns latencies are possible on older platforms like lga775 where the memory controller is pretty far away from the cpu, with it on package , so long as the interconnect is clocked high enough, there shouldn't be any problems.
I think if amd decouples the fabric from the memory speed, or at least provides some ratios to select(3:2 ,5:4 , instead of only 1:1), that would probably negate the issue for the most part.

On a 7nm process, I would want it to crush Intel, not just match a 14nm CPU, almost a year later at that. Anything else is still "catching up". If I wanted 9900K performance, thats what I would have bought last year already.
I want performance to progress forward, and this year apparently is not the time for that yet. Maybe in 2020 with Icelake and whatever AMD has to counter that.
I am almost sure that Zen 2.0 goint to have Equal or even better single core performance then Intel's 9900K, Remember if the ES 8 Core Zen2 was head to head with 9900K thar run @ 4.7Ghz all core turbo, then add ~5% for single core boost and you get at least 9900K single core performance level, what do you need more?

While AMD are on 7 nm
Somebody has to pay for intel's multi year push to 10nm.
