    I fondly remember half year ago Intel disclosed that some of their chips that Apple used affected by some critical bugs. Apple released a patch for it but mentioned that performance would drop to roughly 25%. Although these bugs are hard to implement but still bugs are bugs.

    My question is would the new Mac Pro with the new processors coming out in the Fall 2019 also affected by these bugs?

    Thanks

    No, not right away...

    By the time the 2019 is released, the exact particular threat of today, will have, had been addressed in the new system in my opinion.

    That said, it doesn't mean it will forever be safe.

    If a burglar wants to break into your house, and he is smart and talented, and determined. He will eventually break into your house.

    The trick is to continually upgrade your house (or computer) with countermeasures that make it harder and harder for him (enter the 2019 MP). Hopefully, by the time he's able to defeat your countermeasures, you will have upgraded to even more advanced security system or moved to a new house (computer platform I suppose).

    The newer system is more secure and you should be safe for a while. How long? Who knows...

    This is just my opinion... I actually know nothing, and can barely turn on my own computer, so take from that what you will...

    This is academically debatable since MDS vulnerabilities will always be present while modern processors depends on speculation to get better performance. All modern processors, X86 / ARM / Power etc, are architecturally vulnerable to MDS in a way or another and it's a mitigation process.

    The newest Intel processors have a lot of corrections implemented and work a lot better with the current mitigations, and without the performance problems of old processors, but it's not a resolved issue and MDS will be a problem in the future again.

    Okay, then yes. It's debatable. Threats will always continue to exist and evolve regardless of platform. No system is ever completely safe forever.

    My point is that at the time of release, the exact threat of today, will have been mitigated as much as possible for this platform, to an extent that will have to be considered acceptable by Intel / Apple.

    Some stuff has hardware fixes and some stuff doesn’t . There are several variants with same root name . The Xeon W-32xx processors are part of the Cascade Lake group of products . If you look at table here

    https://www.anandtech.com/show/1330...e-intel-clarifies-whiskey-lake-and-amber-lake

    Even the newer stuff still requires OS and /or firmware fixes for some variants of these issues . But the hardware fixes that Intel has worked out are in Cascade Lake.

    There were some more somewhat based on similar/same foundation bugs that Intel labeled as MDS . However, Intel again says Cascade Lake has fixes for MDS

    “.. MDS is addressed in hardware starting with select 8th and 9th Generation Intel® Core™ processors, as well as the 2nd Generation Intel® Xeon® processor Scalable family ...”
    https://www.intel.com/content/www/us/en/architecture-and-technology/mds.html

    2nd Generation Xeon Scalable is the official product name for part of Cascade Lake group of products . The W-32xx came out after this press release .


    I don’t think anything Apple has released so far has the hardware fixes available . Mac Pro will probably be the first .

    Intel’s Ice Lake May not be all that much better on hardware fixes . It has some better hardware for the fixes and some more hardware to help wth the firmware/OS fixes . There is little indication that it closes all known ones with no overhead .

    I suspect it will be 2021 until Intel largely cleans these know ones up and remove the need for lots of band-aids . This Mac Pro is unlikely to get those processors ( or anything else Apple does this year ) .
