AMD EPYC Turin Power Profile Selection Impact On Performance & Efficiency

([Software] 26 February 11:00 AM EST 4 Comments)

A man is born gentle and weak.
At his death he is hard and stiff.
Green plants are tender and filled with sap.
At their death they are withered and dry.

Therefore the stiff and unbending is the disciple of death.
The gentle and yielding is the disciple of life.

Thus an army without flexibility never wins a battle.
A tree that is unbending is easily broken.

The hard and strong will fall.
The soft and weak will overcome.
