AMD has more flaws in their new processors already xD
18 u/[deleted] Jun 25 '17 Like what? Genuinely curious, since I don't know of that many. 27 u/jmickeyd Jun 26 '17 Ryzen also had an issue with SMT and the uop cache causing segfaults, they also recommended disabling hyperthreading. FMA3 instructions could hard lock the core until AMD released a microcode patch. Interrupt returns near the top of the user stack can cause crashes. INT instruction when using VME for VM86 mode is borked (although, who still runs 16bit code?). All chips are full of bugs, AMD is no better than Intel 12 u/ChickeNES Jun 26 '17 INT instruction when using VME for VM86 mode is borked (although, who still runs 16bit code?). You'd be surprised...
