Aby taky ne, v pripade HW by museli prekopat 50% CPU a to je na 10 let. Proste jenom do mikrokodu zadratujou to, co ted vydavaj v podobe oprav. Jinak receno, pokud by se ti povedlo ziskat mikrokod bez tech oprav, dostanes takovych strednich +20% vykonu navrch.
BTW: 2 servery, generaci (=5let) od sebe. Ten novejsi ma sice 4x vic jader ale prakticky vse na nem je ... pomalejsi, protoze per jadro je o cca 500MHz nizsi takt.

The new desktop processors include protections for the security vulnerabilities commonly referred to as "Spectre", "Meltdown" and "L1TF". These protections include a combination of the hardware design changes we announced earlier this year as well as software and microcode updates.
* Speculative side channel variant Spectre V2 (Branch Target Injection) = Microcode + Software
* Speculative side channel variant Meltdown V3 (Rogue Data Cache Load) = Hardware
* Speculative side channel variant Meltdown V3a (Rogue System Register Read) = Microcode
* Speculative side channel variant V4 (Speculative Store Bypass) = Microcode + Software
* Speculative side channel variant L1 Terminal Fault = Hardware
