Before the release of new updates to Windows 10 May 2019 Update Microsoft traditionally has updated the requirements page to the processor. Now it appears Windows 10, 1903, also known as the may update.
In terms of iron changed nothing. The operating system still supports Intel until the ninth-generation Intel Xeon E-21xx, Atom J4xxx/J5xxx, Atom N4xxx/N5xxx, Celeron, Pentium, AMD 7th generation (A-Series Ax-9xxx & E – Series Ex-9xxx and FX-9xxx), Athlon 2xx, 2xxx Ryzen 3/5/7, Opteron, EPYC and 7xxx Qualcomm Snapdragon 850. But 8cx Snapdragon from Qualcomm, there is no reason. Perhaps this model will come after the release of Windows 10, 19H2 in October-November.
But this is not the only missing link. It is reported that in the list there is no AMD Ryzen 3000, although it is possible that this is a simple typo. Edition Neowin has turned to AMD for comment, but a response has not yet been reported.
Note that the server chips Intel Xeon, AMD Opteron and AMD EPYC is still only supported for Windows 10 and Windows 10 Enterprise. By the way, the missing ARM-processor Snapdragon 8cx expected to work in the corporate sector, because its inclusion is expected in the context of the Enterprise.
Windows 10 IoT Core version of the 1903 do not specify any requirements, but Windows 10 IoT Enterprise SAC 1903 exists, and it contains the same processor requirements as in a full version of Windows.
