AMD did not say whether updates would affect the machine speed, as well as if servers using EPYS processors were heavily affected.
AMD tried to avoid being the focus of Meltdown and Specter, as their processor didn't have Meltdown errors. Although Specter variant 2 is also forcing suppliers to quickly update the firmware. According to Intel, they will try to fix this error for 90% of processors manufactured in the last 5 years before January 15.
AMD also revealed that the Radeon GPU architecture is not affected by Meltdown and Specter. Along with the release of copies and security, AMD will also gradually make official statements.
We still have to wait for news from Apple to see if they have firmware updates for iOS and Mac devices. Android is even more complicated because there are many devices running this OS.
