As is standard practice when a new Windows 10 feature update is being released, Microsoft updated its Windows Processor Requirements page today. It now lists Windows 10 version 1903, also known as the May 2019 Update.
For the first time since Windows 10 version 1703, nothing has changed. The new version of Windows 10 still supports up to ninth-generation Intel processors, Intel Xeon E-21xx, Atom J4xxx/J5xxx, Atom N4xxx/N5xxx, Celeron, Pentium, AMD 7th-gen processors (A-Series Ax-9xxx & E-Series Ex-9xxx & FX-9xxx), Athlon 2xx, Ryzen 3/5/7 2xxx, Opteron, EPYC 7xxx, and the Qualcomm Snapdragon 850.
While nothing has changed, what's more interesting is what's not there. For one thing, Qualcomm's new Snapdragon 8cx chip - which promises the performance of a U-series Core i5 - isn't on the list. That chipset is slated to launch later on this year, so presumably, it's coming after Windows 10 19H2 launches.
Interestingly, AMD's Ryzen 3000 series isn't on there, although that could be a misprint. We've reached out to AMD for comment.
Intel Xeon, AMD Operon, and AMD EPYC chips are still only supported for Windows 10 Pro for Workstations and Windows 10 Enterprise. There's no additional Enterprise-specific data shown, but when the Snapdragon 8cx does show up on the list, it should be the first ARM processor supported for that SKU.
There are no requirements listed for Windows 10 IoT Core version 1903, but Windows 10 IoT Enterprise SAC 1903 is there, and it shows the same processor requirements as full Windows.
