AMD made its upcoming Ryzen 8000 CPU series official earlier this week during a "Meet the Experts" presentation - a roadmap demonstrates that this next-generation "Zen 5" + "Navi 3.5" mainstream desktop processor lineup is expected to arrive in 2024. Leaked information (from last month) points to "Granite Ridge" being AMD's codename for the upcoming processor product range, with high-end examples maxing out at 16 CPU cores across two CCDs. Benchleaks has recently spotted a pair of curious looking AMD engineering samples - entries have appeared on the einstein@home and LHC@home distributed computing platforms.

The mystery SKU seems to be a prototype CPU model that sports 8 cores and 16 threads - the AMD product number (OPN) for this unit is "00-000001290-11_N" which does not correspond to anything currently on the market. A Family ID of 26 is specified - Benchleaks theorizes that this number assignment is "Zen 5" specific - given that the existing Family 25 (19H) identifier was assigned to Zen 3 and 4. It should be noted that one of AMD's alleged test systems appears to have been running unreleased graphics hardware - a non-specific Radeon unit (with 12 GB of VRAM) is mentioned within einstein@home's information dump, this could be a potential mid-range RX 7000-series card. A Radeon RX 7900 GRE GPU with an unusually low video memory allocation of 16 GB is listed in LHC@home's entry.
