Shipping manifests appear to be great sources of pre-release information—only a few hours ago, the existence of prototype AMD "Strix Point" and "Fire Range" mobile processors was highlighted by hardware sleuth harukaze5719. A related leak has appeared online fairly quickly after the discovery of laptop-oriented "Zen 5" chips. momomo_us joined in on the fun, with their exposure of speculated desktop silicon. Two brand-new AMD OPN codes have been linked to the upcoming "Granite Ridge" series of AM5 processors.

100-000001404-01 is likely an eight-core/ sixteen-thread "Zen 5" Ryzen CPU with a 170 W TDP—a stepping designation, B0, indicates engineering sample status. The other listing, 100-000001290-21, seems to be an A0-type engineering sample—leaked info suggests that this a six-core/twelve-thread (105 W TDP) next-gen mainstream desktop processor. AMD is likely nearing the finish line with its Ryzen 9000-series—a new generation of chipsets, including X870E, is reportedly in the pipeline. Additionally, VideoCardz posits that a refresh of 700-series boards could be on the cards. "Granite Range" CPUs are expected to retain the current-gen 6 nm client I/O die (cIOD), as sported by "Raphael" Ryzen 7000-series desktop processors.

AMD is readying the new 800-series motherboard chipset to launch alongside its next-generation Ryzen 9000 series "Granite Ridge" desktop processors that implement the "Zen 5" microarchitecture. The chipset family will be led by the AMD X870E, a successor to the current X670E. Since AMD isn't changing the CPU socket, and this is very much the same Socket AM5, the 800-series chipset will support not just "Granite Ridge" at launch, but also the Ryzen 7000 series "Raphael," and Ryzen 8000 series "Hawk Point." Moore's Law is Dead goes into the details of what sets the X870E apart from the current X670E, and it all has to do with USB4.

Apparently, motherboard manufacturers will be mandated to include 40 Gbps USB4 connectivity with AMD X870E, which essentially makes the chipset a 3-chip solution—two Promontory 21 bridge chips, and a discrete ASMedia ASM4242 USB4 host controller; although it's possible that AMD's QVL will allow other brands of USB4 controllers as they become available. The Ryzen 9000 series "Granite Ridge" are chiplet based processors just like the Ryzen 7000 "Raphael," and while the 4 nm "Zen 5" CCDs are new, the 6 nm client I/O die (cIOD) is largely carried over from "Raphael," with a few updates to its memory controller. DDR5-6400 will be the new AMD-recommended "sweetspot" speed; although AMD might get its motherboard vendors to support DDR5-8000 EXPO profiles with an FCLK of 2400 MHz, and a divider.
