New huge issues

PowerGPU, which builds and sells PCs, says that it records a very impressive number of failures or defects in the latest AMD CPUs.

More precisely, the source data is as follows:

• Ryzen 9 5950X - 8 dead CPUs per 50 units (16%)
• Ryzen 9 5900X - 4 "dead" CPUs at 50 units (8%)
• Ryzen 7 5800X - 4 dead CPUs per 100 units (4%)
• Ryzen 5 5600X - 3 "dead" CPUs at 120 units (2.5%)

And it is not even returns that can happen within 1-2 year, it is dead CPUs.

New PBO coming

Chiplet

IO Die (same as Zen 2)

Chiplets difference

Single thread performance

BIOSTAR also will do standard things and add support to some older MBs, but not 3xx series.

MSI on motherboards support

• X370, B350 and A320 board won't get any support
• B450 and X470 boards will get some support

Main reason that AMD provides fully solid and encrypted AGESA or AMD Generic Encapsulated System Architecture BIOS part. Such way they can prevent old chipset from getting modern CPU support.

Exactly same way they disabled PCIe 4.0 support on older chipsets (actually main M.2 and PCIe x16) spots onall B450 and B350 motherbaords can work in PCIe 4.0.

Such way corporation is making tens of billions of damages and huge ecology impact by forcing unnecessary updates, and all for 3-4 main investors and less than 100 of top managers to get their big cut. This guys are open criminals.

ASUS will provide updated BIOS' for the X470 and B450 chipsets based on AMD's current release schedule of new AGESA code in January 2021. This original report was based on incorrect information.

AMD IO die part

It is exactly same as in Zen 2, cheap as shit, 12nm thing.

x570 chipset is also exactly same die :-)

AMD had much better memory controller in mobile and hybrid latest CPUs, but did not updated IO chiplet, as this required changing masks (aka few less Ferrari cars for AMD top management). All extra profits will be guided to more buybacks and top managers bonuses, none into development.
