Intel server-grade CPUs impacted by new NetCAT attack
Academics from the Vrije University in Amsterdam have detailed today a new attack on Intel CPUs.
Named NetCAT, this is a vulnerability in all Intel chips that support the Data-Direct I/O Technology (Intel DDIO) and Remote Direct Memory Access (RDMA) features.
When these two features are enabled, academics have shown that they can launch an attack on remote, networked computers, and infer certain types of data that is being processed inside the CPU's cache.
Intel Apollo Lake CPUs May Die Sooner Than Expected
As detailed in a recent Product Change Notification (PCN) document, Intel is refreshing four of the company's Celeron and Pentium Apollo Lake processors due to degradation concerns. The problem stems from the same issue that initially cropped up with the C2000 Atom family, which had enough of an impact that Intel had to establish a reserve fund to cover the costs associated with replacing the processors.

I switched to the latest version of mint from an unupdated windows 7 and can definately notice a difference in performance. How do I turn this off?

It depends on whether it was a good or bad difference in performance...

Well, on windows I tried to view some nazi content and when I left the room for a moment the computer restarted itself. On linux it just let me view the content.

Does that mean the SPLC and ADL use Linux? They can't have their computers rebooting every time they want to track the Nahtzees.

Generally Linux was always a bit slower in responsiveness than equivalent Windows, but faster at computation. This is usually connected to different time allocation (you aren't used kernel built for servers?) as well as some device drivers which have really poor routines while handling some data structures, this is especially visible in some storage block device drivers. Linux is also poor in efficiency while using hardware ports and this is by design. It is just not possible to use ports in realtime, you need to purchase another computer or microcontroller for it.

Yes, but it's still a progress: you can't use win7 virtually anytime. (grin)
