Intel Processors to Have "In-silicon" Fixes to Meltdown and Spectre This Year
Intel, which benefited from the post-Q4 public-disclosure of Meltdown and Spectre vulnerabilities in its latest results, is hoping to mitigate its fallout on Q1-2018. The company, along with several other CPU designers, such as AMD and ARM, are firefighting the two devastating security vulnerabilities through OS kernel patches and CPU micro-code updates; which come at a slight expense of performance. In a bid to unnerve investors, company CEO Brian Krzanich announced that Intel is working on "in-silicon" fixes to Meltdown and Spectre.
An "in-silicon" fix would entail a major CPU micro-architecture design that's inherently immune to the two vulnerabilities and yet offers the benefits of modern branch-prediction and speculative execution. Krzanich says processors with in-silicon fixes to the two vulnerabilities will be released to market by the end of 2018.

This is hurting Intel's image more than helping it in the enterprise space (where the most money is made) as well. Many of those customers might be taking a look at otherwise dead in the water EPYC.
As a conspiracy theory, it's pretty awful.
The research on current issues started far longer ago than 6-8 months.
They did not have necessary stuff before to check, mainly know-how (in case of Meltdown and Spectre, necessary details on microarchitectural behaviour of Intel's branch predictor and speculative execution).
They did not always have tools (as an example, one of the methods used in research Flush+Reload is from 2013).
Intel has more know-how but they also have a different perspective on things and I do not mean it in the way they are not interested in plugging up every security problem they find. No doubt they do exactly that for a lot of them. There is a significant amount of people poking at CPUs (among other things) trying to find a hole, a malfunction, a vulnerability. Different approach, often lacking specific knowledge of how things work, poking at a black box, can yield intererting results and ideas that you would not get when looking at a known piece of technology.
Also, the 6000 series is being phased out of manufacturing. Hoping for the 4000 series which is long out of warranty by all standards is just silly.
Intel holds 99% of the server market. Even if it was losing 9% because of EPYC and Meltdown, the 90% that would stay with them, will be forced to update sooner rather than latter. So Intel will gain much more money from that 90%, compared to what would make from a 99% that doesn't feel the need to rush any update. Also Intel does have the stuff and money to create a new line of processors that are truly the most secured in the market. So a NEW Intel image will be created super fast in the end of this year, an image that will look even better compared to that OLD Intel image that was hit by Spectre and especially Meltdown. Meaning MORE sales.
A real, actual fix for both Meltdown and especially Spectre cant realistically be expected before 2021.
Meltdown has been fixed fine. It hurts performance but it works. Spectre effects all modern speculative CPUs. Are you seriously suggesting we recall all present high-performance CPUs? Cause that's when the world ends. No CPU = no problem... yay!
It takes months and years of development, revisions, steppings, validations etc to make sure new hardware works as expected while not introducing new bugs or compatibility issues with existing code.
No way they are that fast putting something in sillicon while they cant get their "rather simple" micro code fix to work properly...

Fixing it requires massive and fundamental changes which maybe has Sapphire Rapids but definitely not a Lake based arch.
