AMD is reportedly building its upcoming "Zen 5" and "Zen 5c" CPU Core Dies (CCDs) on two different foundry nodes, a report by Chinese publication UDN, claims. The Zen 5 CCD powering the upcoming Ryzen "Granite Ridge" desktop processors, "Fire Range" mobile processors, and EPYC "Turin" server processors, will be reportedly built on the 4 nm EUV foundry node, a slightly more advanced node than the current 5 nm EUV the company is building "Zen 4" CCDs on. The "Zen 5c" CCD, or the chiplet with purely "Zen 5c" cores in a high density configuration; on the other hand, will be built on an even more advanced 3 nm EUV foundry node, the report says. Both CCDs will go into mass production in Q2-2024, with product launches expected across the second half of the year.

The "Zen 5c" chiplet has a mammoth 32 cores spread across two CCXs of 16 cores, each. Each CCX has 16 cores sharing a 32 MB L3 cache. It is to cram these 32 cores, each with 1 MB of L2 cache; and a total of 64 MB of L3 cache, that AMD could be turning to the 3 nm foundry node. Another reason could be voltages. If "Zen 4c" is anything to go by, the "Zen 5c" core is a highly compacted variant of "Zen 5," which operates at a lower voltage band than its larger sibling, without any change in IPC or instruction sets. The decision to go with 3 nm could be a move aimed at increasing clock speeds at those lower voltages, in a bid to generationally improve performance using clock speeds, besides IPC and core count. The EPYC processor with "Zen 5c" chiplets will feature no more than six such large CCDs, for a maximum core count of 192. The regular "Zen 5" CCD has just 8 cores in a single CCX, with 32 MB of L3 cache shared among the cores; and TSV provision for 3D Vertical Cache, to increase the L3 cache in special variants.

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.

AMD's next generation Ryzen mobile processor family is undergoing a significant re-positioning of IP within its product stack, as the company introduces the new "elite experience" segment. The "Fire Range" mobile processor is a direct successor to "Dragon Range" MCM, with two 8-core "Zen 5" chiplets. It is essentially a BGA package of the desktop "Granite Ridge" processor, and comes with up to 16 "Zen 5" cores, for flagship gaming notebooks and mobile workstations. A segment below the current "Dragon Range" is the current "Hawk Point" silicon, driving premium experiences. There is a rather large CPU performance gap between the two, as would be the case between the upcoming "Fire Range" and "Kraken Point," which is why AMD is creating the "elite experience" segment, and filling it with "Strix Halo" and "Strix Point," which will square off against Core Ultra 7 and Core Ultra 9 processors, as well as certain HX-segment 14th Gen Core mobile processors. "Strix Point" has a significant core-count increase to 12, along with a large iGPU. We've extensively covered "Strix Point" in our older article, but now we have more information on the elusive "Kraken Point."

"Kraken Point" is codename for AMD's next-generation monolithic mobile processor silicon being designed to power Ryzen processor SKUs competing against the bulk of Intel Core Ultra 5 and Core Ultra 7 SKUs. This chip will be built on a refined 4 nm EUV node by TSMC, and will be monolithic. Its most interesting aspect is the CPU complex. It reportedly features a combination of four regular "Zen 5" cores, and four "Zen 5c" low power cores. All eight cores will likely share a single CCX, which means they share a common L3 cache, which enables easy movement of threads between the two kinds of cores, without having to make round-trips to the DRAM.

AMD is looking to debut its Ryzen 9000 series "Granite Ridge" desktop processors based on the "Zen 5" microarchitecture some time around May-June 2024, according to High Yield YT, a reliable source with AMD leaks. These processors will be built in the existing Socket AM5 package, and be compatible with all existing AMD 600 series chipset motherboards. It remains to be seen if AMD debuts a new line of motherboard chipsets. Almost all Socket AM5 motherboards come with the USB BIOS flashback feature, which means motherboards from even the earliest production batches that are in the retail channel, should be able to easily support the new processors.

AMD is giving its next-gen desktop processors the Ryzen 9000 series processor model numbering, as it used the Ryzen 8000 series for its recently announced Socket AM5 desktop APUs based on the "Hawk Point" monolithic silicon. "Granite Ridge" will be a chiplet-based processor, much like the Ryzen 7000 series "Raphael." In fact, it will even retain the same 6 nm client I/O die (cIOD) as "Raphael," with some possible revisions made to increase its native DDR5 memory frequency (up from the current DDR5-5200), and improve its memory overclocking capabilities. It's being reported that DDR5-6400 could be the new "sweetspot" memory speed for these processors, up from the current DDR5-6000.

AMD concentrated on the promotion of new Zen 4-based APU products at last week's CES trade show, and they even lobbed in a couple of new Zen 3 offerings for PC enthusiasts who are more than happy to stick with Team Red's last generation AM4 socket. Future-focused folks were a little bit disappointed with Team Red keeping quiet about their next-generation "Zen 5" CPUs at CES 2024—one seeker of information, Peter Weltzmaier, turned to a notorious source of hardware leaks on X. Kepler has a decent track record of providing accurate inside tracks—and they more than happy to address Weltzmaier's query regarding the status of AMD's upcoming "Granite Ridge" desktop CPU series.

Kepler believes that Granite Ridge has reached the mass production phase, but did not provide any further elaboration beyond a brief reply on social media—this information should be taken with a grain of salt. We have not heard a lot about Granite Ridge processors since last November, with AMD choosing to not preview next-gen desktop processors at a December "Advancing AI" event. The rumor mill proposed that XDNA-based Ryzen AI acceleration will not be a key feature present on Granite Ridge and a mobile-oriented derivative called "Fire Ridge."

With Windows 11 23H2 setting the stage for increased prevalence of AI in client PC use cases, the new hardware battleground between AMD and its rivals Intel, Apple, and Qualcomm, will be in equipping their mobile processors with sufficient AI acceleration performance. AMD already introduced accelerated AI with the current "Phoenix" processor that debuts Ryzen AI, and its Xilinx XDNA hardware backend that provides a performance of up to 16 TOPS. This will see a 2-3 fold increase with the company's 2024-25 mobile processor lineup, according to a roadmap leak by "Moore's Law is Dead."

At the very top of the pile, in a product segment called "ultimate compute," which consists of large gaming notebooks, mobile workstations, and desktop-replacements; the company's current Ryzen 7045 "Dragon Range" processor will continue throughout 2024. Essentially a non-socketed version of the desktop "Raphael" MCM, "Dragon Range" features up to two 5 nm "Zen 4" CCDs for up to 16 cores, and a 6 nm cIOD. This processor lacks any form of AI acceleration. In 2025, the processor will be succeeded with "Fire Range," a similar non-socketed, mobile-friendly MCM that's derived from "Granite Ridge," with up to two 4 nm "Zen 5" CCDs for up to 16 cores; and the 6 nm cIOD. What's interesting to note here, is that the quasi-roadmap makes no mention of AI acceleration for "Fire Range," which means "Granite Ridge" could miss out on Ryzen AI acceleration from the processor. Modern discrete GPUs from both NVIDIA and AMD support AI accelerators, so this must have been AMD's consideration to exclude an XDNA-based Ryzen AI accelerator on "Fire Range" and "Granite Ridge."

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 is aiming to launch its Ryzen 8000 desktop CPUs, codenamed "Granite Ridge," at some point next year. The next generation Zen 5 core microarchitecture is expected to arrive alongside (Navi) RDNA 3.5 iGPU cores according to the last batch of Team Red product roadmaps. Today, hardware tipsters Olrak29_ and Kepler_L2 have made claims on social media that part of the Ryzen 7000 CPU legacy will continue with the succeeding desktop processor lineup—we already know that Granite Ridge will exist as a Socket AM5 package, but today's leak proposes that these next-gen chips are lined up to utilize the same IO die as sported by AMD's current Zen 4 desktop family.

These new rumors suggest that the "reused" Ryzen 7000 IOD (I/O Die) chiplet will grant the familiar allocation of 28 PCIe Gen 5 lanes, memory controllers, USB functions, plus RDNA 2 iGPU cores. Wccftech points out that: "...interestingly, AMD lists the Ryzen 7000 "desktop" CPUs with Navi 3.0 support whereas the Radeon 710M iGPU in fact is based on the RDNA 2 graphics core. The next-gen lineup was mentioned to support the newest RDNA 3.5 GPU core which will be coming to the Strix APU family next year but that isn't the case either." The article proposes that "RDNA 3.5 GPU cores on the AM5 platform" could arrive with the advent of upcoming Ryzen APUs—namely 6 nm Rembrandt (6000G) and 4 nm Phoenix (7000G) desktop solutions.

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.

In no mood to cede its market-share growth to Intel, AMD has reportedly decided to accelerate the development of its next-generation "Zen 5" microarchitecture for debut within 2023. In its mid-2022 presentations, AMD had publicly given "Zen 5" a 2024 release date. This is part of a reading-in-between the lines for a recent GIGABYTE press release announcing server platforms powered by relatively low-cost Ryzen desktop processors. The specific sentence from that release reads "The next generation of AMD Ryzen desktop processors that will come out later this year will also be supported on this AM5 platform, so customers who purchase these servers today have the opportunity to upgrade to the Ryzen 7000 series successor."

While the GIGABYTE press release speaks of a next-generation Ryzen desktop processor, it stands to reason that it is referencing an early release of "Zen 5," and since AMD shares the CPU complex dies (CCDs) between its Ryzen client and EPYC server processors, the company is looking at a two-pronged upgrade to its processor lineup, with its next-generation EPYC "Turin" processor competing with Xeon Scalable "Emerald Rapids," and Ryzen "Granite Ridge" desktop processors taking on Intel's Core "Raptor Lake Refresh" and "Meteor Lake-S" desktop processors. It is rumored that "Zen 5" is being designed for the TSMC 3 nm node, and could see an increase in CPU core count per CCD, up from the present 8. TSMC 3 nm node goes into commercial mass-production in the first half of 2023 as the TSMC N3 node, with a refined N3E node slated for the second half of the year.

AMD in its 2022 Financial Analyst Day presentation announced the codename for the second generation of Ryzen desktop processors for Socket AM5, which is "Granite Ridge." A successor to the Ryzen 7000 "Raphael," the next-generation "Granite Ridge" processor will incorporate the "Zen 5" CPU microarchitecture, with its CPU complex dies (CCDs) built on the 4 nm silicon fabrication node. "Zen 5" will feature several core-level designs as detailed in our older article, including a redesigned front-end with greater parallelism, which should indicate a much large execution stage. The architecture could also incorporate AI/ML performance enhancements as AMD taps into Xilinx IP to add more fixed-function hardware backing the AI/ML capabilities of its processors.

The "Zen 5" microarchitecture makes its client debut with Ryzen "Granite Ridge," and server debut with EPYC "Turin." It's being speculated that AMD could give "Turin" a round of CPU core-count increases, while retaining the same SP5 infrastructure; which means we could see either smaller CCDs, or higher core-count per CCD with "Zen 5." Much like "Raphael," the next-gen "Granite Ridge" will be a series of high core-count desktop processors that will feature a functional iGPU that's good enough for desktop/productivity, though not gaming. AMD confirmed that it doesn't see "Raphael" as an APU, and that its definition of an "APU" is a processor with a large iGPU that's capable of gaming. The company's next such APU will be "Phoenix Point."

Today, we have talked about AMD's upcoming Raphael lineup of processors in the article you can find here. However, it seems like the number of leaks on AMD's plans just keeps getting greater. Thanks to the "itacg" on Weibo, we have learned that AMD's Ryzen 8000 desktop series of processors are reportedly codenamed as Granite Ridge. This new codename denotes the Zen 5 based processors, manufactured on TSMC's 3 nm (N3) node. Another piece of information is that AMD's Ryzen 8000 series APUs are allegedly called Strix Point, and they also use the 3 nm technology, along with a combination of Zen 5 and Zen 4 core design IPs. We are not sure how this exactly works out, so we have to wait to find out more.
