No, the Intel CEO indicated 8th Gen Core. Just means a new stepping will come out. It makes sense as 8th Gen Core products will still be shipping for the next several years.

I was thinking the same thing. Why do they HAVE to build SE into the chips in the first place. Like if you clearly know what the issue is, why continue to build chips with that "feature"? I get that it saves time, but at the cost of security? Is this lost on them or am I missing something here?
That last line in this article is conjecture. Apple’s patches for these vulnerabilities have significantly slowed down my MacBook.
Wish there were a way to disable them like in Windows.

That's not right.
I got a logic board replacement on MBP 15" (Late 2016) last week. After the repair my MBP came with 10.12.3 installed and I upgrade to 10.13.3. As per Geekbench CPU benchmark, there is 10% performance loss as below:
https://browser.geekbench.com/v4/cpu/compare/7364843?baseline=7353633
So far the performance has gone down progressively with Mac OS updates over time so I haven't realised but it was quite evident when I ran Geekbench before and after the upgrade with no other changes to the default installation.
Bit late isn’t it.... hmm seems Intel couldn’t of cared less until they were exposed, a bit like Apple and it’s battery scandle...
So 2019 before see in any Macs. Expected? Not very good track record even with 6 month window giving themselves.
That's why Torvalds had a major rant about it.
Great progress, until other devastating bugs come to be revealed that are hardware-flawed too
With no speculative execution at all, just brutally turned off, I'd say your processor slows down by a factor 3 or so. That means your high end Intel processor runs slower than the slowest AMD processor.
Honestly, the cure is worse than the disease. Nobody knew about the issue for decades and look where we are. Someone mentions it and it becomes this HUGE CRISIS. For what? No reason what so ever. It would have been better to not say anything at all to be honest.
Security stuff these past few years is getting hugely out of hand. Making huge deals out of nothing. It's quicker for me to go through your trash, social media, email you or text you and get whatever I need than take the time to exploit something nearly impossible to do on your stupid computer.
Hell, most people these days practically give away everything on social media anyways.
I read this and I see, no new Mac Mini until 2020 chip release.... But I may be cynical.
I have seen though that Intel DID know about it for a long time, it did nothing about it. That’s an issue when it’s such a security breach, and it is a very very very big something, think how much of the planets infrastructure relies on Intel processors, and they are all open to some pretty serious hacking. Cyber ware fare and hacking idiots are bad enough without Intel opening the door to them wide open.

This is what I was coming to ask. I've got an Intel 8700K, which is 8th gen. So, they are just releasing a new version with a hardware fix. What kind of warranty do processors have? Maybe I deserve a free upgrade.
I thought Ice Lake (9th gen) would be the first generation to be fixed. This will be confusing to have different fixed and unfixed variants of the same generation which itself is already confusing with a mix of Kaby Lake R, Coffee Lake, Cannonlake and possibly Coffee Lake R.
only a matter of time before a class action lawsuit pushes computer tech companies to forcing Logic Boards to be replaced in the name of updating CPUs with "fixed" vulnerabilities.
I have to wonder... if mitigating these issues does NOT result in a significant or even measurable decline in performance, (as was written, "Apple's software mitigations for the vulnerabilities have not resulted in any significant measurable decline in performance," in the article,) then either the mitigation doesn't actually DO anything, or the feature itself didn't actually do anything, did it?
I mean, if I can use an analogy here, if you've been taking medicine for YEARS that's supposed to improve your health, and it turns out to be toxic, so you have to stop taking it, and whatever it WAS supposedly doing for you is no longer being done, but you have no meaningful harm from NOT receiving anymore, whatever the benefit you were supposedly deriving from taking the medication, what was it ever actually DOING in the first place?
Unless you're going to say that the mitigation allows the techniques of speculative execution, and whatever the other thing was, but in a way that magically does NOT allow for loss of data or arbitrary code execution... how are we supposed to believe we're safe, and have taken no "significant, measurable" hit to performance? OR... was the performance gained through the use of these techniques trivial in the first place? Can they give us a PERCENT degradation on performance of particular tasks, or percent in general? What is their notion of "significant, measurable?" Do they mean measurable with a sundial? Because a lot of these benchmark utilities produce results with several significant figures.
The lack of specifics I find suspicious. So, hence, I'm curious as to what they are, as should anyone else who paid for these products too. When this happens in other fields of endeavor, like when cars are revealed to have safety issues, recalls are issued, and the items are FIXED or replaced. Will we see that here?

Intel CEO Brian Krzanich today announced that its next-generation Xeon Scalable (Cascade Lake) processors and its 8th-generation Intel Core processors will feature redesigned components to protect against the Spectre and Meltdown vulnerabilities that affect all modern processors.
Spectre variant 1 of the vulnerabilities will continue to be addressed in software, while Intel is implementing hardware-based design changes to offer future protection against Spectre variant 2 and Meltdown variant 3.
Intel's new Xeon Scalable processors and its 8th-generation Intel Core processors are expected to start shipping out to manufacturers in the second half of 2018.
Ahead of the hardware changes, Intel says that software-based microcode updates have now been issued for 100 percent of Intel products launched in the past five years, and all customers should make sure to continue to keep their systems up-to-date with software updates.
Krzanich also reaffirmed Intel's commitment to customer-first urgency, transparent and timely communications, and ongoing security reassurance.
Apple began addressing the Meltdown and Spectre vulnerabilities back in early January with the release of iOS 11.2, macOS 10.13.2, and tvOS 11.2, which introduced mitigations for Meltdown. Subsequent iOS 11.2.2 and macOS High Sierra 10.13.2 Supplemental updates introduced mitigations for Spectre, as did patches for both macOS Sierra and OS X El Capitan in older machines.
Apple's software mitigations for the vulnerabilities have not resulted in any significant measurable decline in performance.
