intel Skylake and Kabylake CPUs - Broken Hyperthreading

Fudzilla wrote an article about how intel's Skylake and Kabylake CPUs have a broken Hyperthreading and users must disable it for the meantime.

 

Originally from debian.org - 

Quote

This advisory is about a processor/microcode defect recently identified on Intel Skylake and Intel Kaby Lake processors with hyper-threading enabled.  This defect can, when triggered, cause unpredictable system behavior: it could cause spurious errors, such as application and system misbehavior, data corruption, and data loss.

Fudzilla -

Quote

Intel said that under complex micro-architectural conditions, short loops of less than 64 instructions that use AH, BH, CH or DH registers as well as their corresponding wider register (eg RAX, EAX or AX for AH) may cause unpredictable system behaviour.

This doesn't only affect Linux systems but other systems as well.

 

...i5 users rejoice! ...perhaps

You can bark like a dog, but that won't make you a dog.

You can act like someone you're not, but that won't change who you are.

How I plan my builds -

For me I start with the "There's no way I'm not gonna spend $1,000 on a system."

Followed by the "Wow I need to buy the OS for a $100!?"

Then "Let's start with the 'best budget GPU' and 'best budget CPU' that actually fits what I think is my budget."

Realizing my budget is a lot less, I work my way to "I think these new games will run on a cheap ass CPU."

Then end with "The new parts launching next year is probably gonna be better and faster for the same price so I'll just buy next year."

Dang you're right, didn't see it.

 

How to remove this?
