    Not a problem until the mitigation via kernel update enforces it. I'm still curious for other confirmations about increase in watts drawn for Gen9+, I'll take the local vulnerability over losing a notable hit on battery life..

    Intel sucks. It needs real competition, more than AMD and Chinese-only market CPUs derived from VIA.

    It's a mitigation, not a fix. Disabling an entire kernel module and losing functionality is NOT a fix unless the whole hardware is malware and must be turned off.

    Which in case of Intel it's not THAT far off from the truth anyway.

    Does Intel Graphics even run Crysis? I'm pretty sure they still can't.

    ​​​​​Its the opposite case, if it was important enough it would be fixed on 0 day, it's not a major problem but you do want to mitigate it then disable i915 for now. Its not a recommendation for normal users.

    You'd have to run a malicious binary anyway, which can already do whatever it wants, and far worse than the end result of this.

    The funny thing here is that I spent the last two years with my older ryzen based laptop getting faster and faster as new updates came out. In fact I'd have to say that the drivers are now pretty good and kernel support is close to complete. To put it another way most of the grief of the bleeding edge has passed. I'm expecting Renoir to be even better.

    So much better in fact that I'm seriously considering an early upgrade. The only thing it will not be is an HP! HP BIOS support sucks and their batteries simply don't last and are hard to replace. To that end I'm looking for a model/manufacture that builds decent hardware and actually supports it.
