    How do you think intel can sort this? The only way is a complete new arch

    I have asked both my vps providers to move me to an epyc server as they keep doing reboot maintenance for intel patches.

    Will all the issues in this thread also apply to the 9700k? Just got the funds to buy a new cpu, mono and ram but don’t want performance killed off over the months with bios updates to fix these issues

    Any of the hyperthreading issues obviously won't impact the 9700k. Three issues have been resolved in hardware in the 9 series and the fixes for the rest are down to patches and updates to the affected os, software, bios or microcode that runs on the cpu.
    There is no way of escaping the issue (right now) because it is so prevalent, however you don't need to install every fix. Weigh up the cost of the fix vs the likelihood that your machine is vulnerable and going to be targeted and decide for yourself if the performance hit is worth it.

    There are going to be new exploits going forward as well as fixes for those exploits. Security is a game of cat and mouse. They can predict what avenues of attack might be used and try to mitigate the threat, but until the hardware and software is in the wild you don't know how secure it really is. Even years after release like in this instance.

    You may see less issues with ARM or AMD depending on your environment, but that doesn't mean there wont be issues in the future that require fixes that impact performance. Hopefully this isn't the case, in which case AMD is a slightly more secure and viable alternative given that not all the exploits are proven to affect their current hardware.

    Do what I did, give up until Rome is here! In the meantime I implemented Darktrace network AI and push every single little bit of traffic at it. Properly pricey solution to what "might be a problem". Awesome bit of kit though.

    Thank you for taking the time to reply. I would wait but my x58 mobo died a few weeks back and now needs replacing. Got a budget of £550 and can just squeeze in a 9700k, 8gb 3200mhz ram and a gigabyte z390 UD mobo

    I don’t upgrade often so want to get the best I can for my money and all I do is game on it and the forums so not used for much else

    Unbelievable.

    I should have gone with EPYC...

    Another reason to go AMD this generation. Intel's architecture is inherently insecure, and even the recent ones still need mitigation.

    Intel have the cheek to charge you more for insecure chips, glad I went zen.

    We are fortunate really that the Intel Management Engine hasn't been exploited yet as if that ever happens in a serious way there is little you can do but take an Intel CPU completely offline:

    It isn't so much the architecture is inherently insecure any more or less than any other though - even my 4820K is 6 years old let alone the architecture that these CPUs are based on - that is a long time in security terms - though if they'd have taken a less head in sand approach the last couple of generations could have had a full raft of hardware mitigations.

    Just read about the new one a 3 percent performance Impact, oh well glad the desktop is AMD
