The latest version of HWiNFO has preliminary support for AMD's next-gen Navi GPU architecture, but also a new mysterious CPU architecture from Intel teased as Emmitsburg.
HWiNFO v6.04 also features added support for Intel's new Cooper Lake and Snow Ridge, as well as full monitoring support for AMD's still-kinda-new Radeon VII graphics card. There is also 'improved' Zen 2 support with the latest version of HWiNFO and a bunch of other things tweaked, added, and now supported. You can grab HWiNFO v6.04 right here.
A few people replied to the original tweet, including Ashraf Eassa who is a Senior Technology Specialist with The Motley Fool, where he said Emmitsburg is "probably CPL/ICX PCH", meaning that Emmitsburg will be the chipset codename for the upcoming Cooper Lake/Ice Lake-X platform on LGA4189. He added that he feels like this "will be the last PCH before SPR. Then I/O will just be another chiplet on the package".
