Tipster Claims AMD "Kraken Point" APU Configured with Zen 5 & Zen 5c Cores

Everest (@Olrak29_) has kept track of many AMD processor families over the past couple of years—his latest insight provides an early look at the alleged internal makeup of Team Red's "Kraken Point" APU series. The rumor mill has designated these next-gen mobile processors as 2025 follow-ups to the recently launched Ryzen 8040 "Hawk Point" family of mainstream laptop APUs. The tipster's initial social media post only mentioned the presence of both Zen 5 and Zen 5c cores within Kraken Point processors, but he later clarified that a total of eight cores would include four large units and four smaller types. TPU's past coverage of Kraken Point pointed to rumors of an 8-core, 16-thread configuration, but leaked slides (from late 2023) did not mention the integration of efficiency-tuned Zen 5c "Prometheus" cores, along with presumed Zen 5 "Nirvana" cores.

Everest's continuous flow of insider information reveals that "Kraken Point" shares many "Hawk Point" traits—four workgroup processors (WGP) could be present on final retail products, granting eight compute units (8 CUs in total). He responded to a query regarding AMD's choice of integrated graphics technology—the succinct answer being RDNA 3.5. Past leaks allege that XDNA 2 will drive the NPU side of things—offering a performance range of around 45 to 50 TOPS. The Kraken Point APU is believed to be sticking with a safe monolithic die design, manufactured on a non-specific 4 nm process. Team Red is rumored to be in TSMC's order books for all sorts of next generation silicon.

AMD Zen 5 Microarchitecture Referenced in Leaked Slides

A couple of slides from AMD's internal presentation were leaked to the web by Moore's Law is Dead, referencing what's allegedly the next-generation "Zen 5" microarchitecture. Internally, the performance variant of the "Zen 5" core is referred to as "Nirvana," and the CCD chiplet (CPU core die) based on "Nirvana" cores, is codenamed "Eldora." These CCDs will make up either the company's Ryzen "Granite Ridge" desktop processors, or EPYC "Turin" server processors. The cores themselves could also be part of the company's next-generation mobile processors, as part of heterogenous CCXs (CPU core complex), next to "Zen 5c" low-power cores.

In broad strokes, AMD describes "Zen 5" as introducing a 10% to 15% IPC increase over the current "Zen 4." The core will feature a larger 48 KB L1D cache, compared to the current 32 KB. As for the core itself, it features an 8-wide dispatch from the micro-op queue, compared to the 6-wide dispatch of "Zen 4." The integer execution stage gets 6 ALUs, compared to the current 4. The floating point unit gets FP-512 capabilities. Perhaps the biggest announcement is that AMD has increased the maximum cores per CCX from 8 to 16. At this point we don't know if it means that "Eldora" CCD will have 16 cores, or whether it means that the cloud-specific CCD with 16 "Zen 5c" cores will have 16 cores within a single CCX, rather than spread across two CCXs with smaller L3 caches. AMD is leveraging the TSMC 4 nm EUV node for "Eldora," the mobile processor based on "Zen 5" could be based on the more advanced TSMC 3 nm EUV node.

AMD Zen 5 "Nirvana" and Zen 6 "Morpheus" Core Codenames Leaked, Confirm Foundry Nodes

An AMD engineer inadvertently leaked the core codenames of the company's upcoming "Zen 5" and "Zen 6" microarchitectures. It's important to understand here what has been leaked. "Zen 5" and "Zen 6" are microarchitecture names, just like the current "Zen 4" and past "Zen 3" or older. AMD uses codenames for the CCD (CPU complex dies) based on these microarchitectures, which it shares between Ryzen client and EPYC enterprise processors. For example, the CCD codename for "Zen 3" is "Brekenridge," and for "Zen 4" it is "Durango." AMD also uses codenames for the CPU cores themselves. "Zen 3" CPU cores are codenamed "Cerebrus," and "Zen 4" CPU cores "Persphone." And now, the leak:

The CCD based on the upcoming "Zen 5" microarchitecture is codenamed "Eldora," and the "Zen 5" CPU core itself is codenamed "Nirvana." There's no codename for the CCD based on "Zen 6," but its CPU cores are codenamed "Morpheus." The "Zen 5" microarchitecture will be based on the 3 nm EUV foundry node; while "Zen 6" will be 2 nm EUV. The engineer in the screenshot is contributing to the power-management technology behind "Zen 5" and "Zen 6," and states that their work on "Zen 5" spanned January-December of 2022, which means the development phase of the next "Zen" architecture is probably complete, and the architecture is undergoing testing and refinement. It's also claimed that work on at least the power-management aspect of "Zen 6" has started from January 2023.
