    Phoronix: LVI Attack Hits Intel SGX - Defeats Existing Mitigations, More Performance Hits

    Load Value Injection (LVI) is being disclosed today as a new class of transient-execution attacks and the researchers claim can defeat all existing mitigations around Meltdown, Foreshadow, Zombieload, RIDL and Fallout. The researchers say LVI can affect virtually any access to memory and compiler-based mitigations can be expensive...

          My 10 core i9 suddenly feels like a big action replay. Were any of the former AR engineers hired by intel?

            Intel should just quit x86, nothing will be missed.

              ARM64 is looking rather nice right about now. Just need a super fast x86-64 translator for Steam games and Wine.

                Cheers!

                  Any specific reason you would buy a i9 nowadays, with AMD being an absolutely compelling option in the high core count area?

                  Genuinely curious, please don't read this with a "how dumb" tone.

                    Not a hardware guy, but the first prerequisite (Incorrect transient forwarding) already sounds crazy to me.
                    What the h*** are they doing inside the processors sold to us?
