AMD is working on a full stack of Zen 5 "Ryzen" CPU families including Granite Ridge, Fire Range, Strix Halo, Strix & Krackan. These families will target various desktop and mobile platforms with chiplet and monolithic offerings.
It won't be the first time that we have talked about AMD's Zen 5 CPU families featured in the Ryzen segment. We know that the initial round of chips will include a total of five product lineups starting with the highest-end segment which is desktop. A few hours ago, we covered that AMD's Zen 5 core architecture is rumored to feature an IPC improvement of around 10%.
The AMD Granite Ridge and Fire Range CPUs will be very similar to each other. The former is aimed at desktops while the latter is aimed at mobile platforms. Both feature the same Zen 5 dies but in a slightly varied manner since the mobile chips are tuned with conservative power limits in mind. The two Zen 5 families will feature an MCM package with up to two Zen 5 CCDs based on the N4 node & a single Raphael IOD based on the N6 node.
In terms of configuration, both AMD Granite Ridge & Fire Range "Ryzen" CPUs will feature up to 16 Zen 5 cores and 32 threads. Each CCD will retain the 32 MB L3 cache which will be shared with each core and there's also a mention of up to 128 MB of L3 cache (X3D) variants which means we aren't getting dual CCD configurations just yet despite the company having several prototypes of those hidden in the labs.

Other details include the use of two RDNA 3 Compute Units in a single WGP and 28 PCIe 5.0 lanes. It's interesting that RDNA 3 CUs are mentioned instead of RDNA 2. The IOD is supposedly the same as Raphael chips and that packed RDNA 2 CUs. So RDNA 3 might be listed by mistake or we might be looking at a slightly upgraded version of the Raphael iGPU.
Neither the desktop nor laptop SKUs will feature an NPU but they will be supported on existing platforms. For desktops, it's going to be AM5 and motherboard vendors are already rolling out BIOS support. One can also expect better DDR5 memory support in the upcoming Ryzen Desktop lineup.
