wasn’t the ryzen susceptible to hacking or something? Or had soem defect that slows it down or soemthing?

You mean Qualcomm joins Intel, Apple, Arm, AMD in confirming its CPUs suffer hack bugs , too

Then you have, AMD Immune to Crippling MDS Vulnerabilities

Perhaps unsurprisingly at this point, new security vulnerabilities have been found in Intel's CPUs dating all the way back to 2008. Known as Zombieload, RIDL, Fallout, and MDS (Intel's official naming), these holes in Intel's architecture are the latest in a string of vulnerabilities that have been revealed one after the other since the early 2018 debut of Meltdown. Meanwhile, AMD maintains that Zombieload, just like Meltdown, Foreshadow, and Spoiler before, only affects Intel processors and not any produced by AMD.

It wasn’t just Ryzen. It was every CPU with branch prediction logic, including Intel and ARM.
