Lets assume worst case performance drop of 30% on average
then final performance level is down to 0.7^15 = 0.0047 times of original performance or performance drop up to 99.53%. for Intel.
or going performance go back to performance level
log 200/log 2 = 7.6438 years ago If we assume devolved "performance version" of Moore's law.
For AMD
0.7^4=0.240 so 76% performance drop at most.
I know that maximum performance drop for every bug at same time is highly improbable and impossible in real world applications.
