In a “Meet the Experts” event earlier this week, AMD made the Ryzen 8000 CPU series public. A roadmap shows that this next-generation “Zen 5” + “Navi 3.5” mainstream desktop processor lineup is anticipated to launch in 2024. According to information that was leaked (last month), AMD’s codename for the new processor product line is “Granite Ridge,” with high-end models having a maximum of 16 CPU cores spread across two CCDs. A pair of intriguing-looking AMD engineering samples have recently been discovered by Benchleaks; entries have appeared on the einstein@home and LHC@home distributed computing platforms.

The mysterious SKU appears to be a prototype CPU with 8 cores and 16 threads; it has the AMD product number (OPN) “00-000001290-11_N,” which does not match anything that is currently available on the market. Given that the previous Family 25 (19H) identity was given to Zen 3 and 4, Benchleaks speculates that this number assignment is “Zen 5” specific and specifies a Family ID of 26. It should be noted that one of AMD’s purported test systems appears to have been using unreleased graphics hardware; einstein@home’s information dump mentions a non-specific Radeon unit (with 12 GB of VRAM), which may be a future mid-range RX 7000-series card. The entry for LHC@home lists a Radeon RX 7900 GRE GPU with an extremely small 16 GB video memory allocation.
