In case you missed it, AMD's new madcap enthusiast silicon engineering effort, the "Strix Halo," is real, and comes with the Ryzen AI Max 300 series branding. These are chiplet-based mobile processors with one or two "Zen 5" CCDs—same ones found in "Granite Ridge" desktop processors—paired with a large SoC die that has an oversized iGPU. This arrangement lets AMD give the processor up to 16 full-sized "Zen 5" CPU cores, and an iGPU with as many as 40 RDNA 3.5 compute units (2,560 stream processors), and a 256-bit LPDDR5/x memory interface for UMA.

"Strix Halo" is designed for ultraportable gaming notebooks or mobile workstations where low PCB footprint is of the essence, and discrete GPU is not an option. For enthusiast gaming notebooks with discrete GPUs, AMD is designing the "Fire Range" processor, which is essentially a mobile BGA version of "Granite Ridge," and a successor to the Ryzen 7045 series "Dragon Range." The Ryzen AI Max series has three models based on CPU and iGPU CU counts—the Ryzen AI Max 395+ (16-core/32-thread with 40 CU), the Ryzen AI Max 390 (12-core/24-thread with 40 CU), and the Ryzen AI Max 385 (8-core/16-thread, 32 CU). An alleged Ryzen AI Max 390 engineering sample surfaced on the Geekbench AI benchmark online database.

The first die shot of AMD's new 4 nm "Strix Point" mobile processor surfaced, thanks to an enthusiast on Chinese social media. "Strix Point" is a significantly larger die than "Phoenix." It measures 12.06 mm x 18.71 mm (L x W), compared to the 9.06 mm x 15.01 mm of "Phoenix." Much of this die size increase comes from the larger CPU, iGPU, and NPU. The process has been improved from TSMC N4 on "Phoenix" and its derivative "Hawk Point," to the newer TSMC N4P node.

Nemez (GPUsAreMagic) annotated the die shot in great detail. The CPU now has 12 cores spread across two CCX, one of which contains four "Zen 5" cores sharing a 16 MB L3 cache; and the other with eight "Zen 5c" cores sharing an 8 MB L3 cache. The two CCXs connect to the rest of the chip over Infinity Fabric. The rather large iGPU takes up the central region of the die. It is based on the RDNA 3.5 graphics architecture, and features 8 workgroup processors (WGPs), or 16 compute units (CU) worth 1,024 stream processors. Other key components include four render backends worth 16 ROPs, and control logic. The GPU has its own 2 MB of L2 cache that cushions transfers to the Infinity Fabric.

AMD is readying a successor to its Ryzen 7045 series "Dragon Range" mobile processor for gaming notebooks and portable workstations. While we don't know its processor model naming yet, the chip is codenamed "Fire Range." We are learning that it will retain the FL1 package as "Dragon Range," which means it will be pin-compatible. This would significantly reduce development costs for notebook OEMs, as they can simply carry over their mainboard designs from their notebooks based on "Dragon Range."

"Fire Range" is essentially a mobile BGA version of the upcoming Ryzen 9000 "Granite Ridge" desktop processor. The FL1 package measures 40 mm x 40 mm in size, and has substrate for two CCDs and a cIOD, just like the desktop chip. "Fire Range" hence features one or two 4 nm "Zen 5" CCDs, depending on the processor model, and the 6 nm client I/O die. Much like "Dragon Range," the "Fire Range" chip will lack support for LPDDR5, and rely on conventional PC DDR5 memory in the SO-DIMM or CAMM2 form-factors. Besides the CPU core count consisting exclusively of full-sized "Zen 5" cores, the main flex for "Fire Range" over "Strix Point" will be its 28-lane PCIe Gen 5 root-complex, which can wire out the fastest discrete mobile GPUs, as well as drive multiple M.2 NVMe slots with Gen 5 wiring, and other high-bandwidth devices, such as Thunderbolt 4, USB4, or Wi-Fi 7 controllers wired directly to the processor.

AMD's upcoming "Strix Halo" mobile processor that features up to 16 "Zen 5" CPU cores and a powerful iGPU with 40 compute units, is beginning to surface in online benchmark databases. We've gone into the juicy technical bits about the processor in our older articles, but put simply, it is a powerful mobile processor meant to square off against the likes of the Apple M3 Pro and M3 Max. A chiplet-based processor, much like the upcoming "Granite Ridge" desktop processor and "Fire Range" mobile processor, "Strix Halo" features up to 16 full-sized "Zen 5" cores, as it uses up to two of the same "Eldora" CCDs as them; but wired to a large I/O die that contains the oversized iGPU, and an NPU, besides the memory controllers. The iGPU has 40 compute units (2,560 stream processors), and is based on the RDNA 3.5 graphics architecture, while the NPU is the same 50 TOPS-class unit carried over from "Strix Point."

A prototype HP laptop powered by a "Strix Halo" processor that uses a single 8-core "Zen 5" CCD, was spied on the web. This chip has eight full-sized "Zen 5" cores that share a 32 MB L3 cache. The iGPU on the I/O die has its own 32 MB Infinity Cache memory that cushions memory transfers. In our older reports, we speculated as to what the memory interface of "Strix Halo" would be. It turns out that the chip exclusively features a 256-bit wide LPDDR5X memory interface, which is double the bus width of "Strix Point." This is essentially what a "quad-channel DDR5" memory interface would be, and AMD is using a memory speed standard of at least LPDDR5X-8000. From the machine's point of view, this would be just a couple of hardwired LPDDR5X chips, or a pair of LPCAMM 2 modules. Back to the benchmarks, and we are shown a single-thread CPU score of 2099 to 2177 points, and a multithreaded score ranging between 5477 points to 13993 points. The laptop was tested with an unknown version and distribution of Linux. The CPU cores are shown boosting up to 5.35 GHz.

Apparently the AMD "Strix Halo" processor is real, and it's large. The chip is designed to square off against the likes of the Apple M3 Pro and M3 Max, in letting ultraportable notebooks have powerful graphics performance. A chiplet-based processor, not unlike the desktop socketed "Raphael," and mobile BGA "Dragon Range," the "Strix Halo" processor consists of one or two CCDs containing CPU cores, wired to a large die, that's technically the cIOD (client I/O die), but containing an oversized iGPU, and an NPU. The point behind "Strix Halo" is to eliminate the need for a performance-segment discrete GPU, and conserve its PCB footprint.

According to leaks by Harukaze5719, a reliable source with AMD leaks, "Strix Halo" comes in a BGA package dubbed FP11, measuring 37.5 mm x 45 mm, which is significantly larger than the 25 mm x 40 mm size of the FP8 BGA package that the regular "Strix Point," "Hawk Point," and "Phoenix" mobile processors are built on. It is larger in area than the 40 mm x 40 mm FL1 BGA package of "Dragon Range" and upcoming "Fire Range" gaming notebook processors. "Strix Halo" features one or two of the same 4 nm "Zen 5" CCDs featured on the "Granite Ridge" desktop and "Fire Range" mobile processors, but connected to a much larger I/O die, as we mentioned.

Enthusiasts on the ChipHell forum scored an alleged image of AMD's upcoming "Strix Halo" mobile processor, and set out to create some highly plausible schematic slides. These are speculative. While "Strix Point" is the mobile processor that succeeds the current "Hawk Point" and "Phoenix" processors; "Strix Halo" is in a category of its own—to offer gaming experiences comparable to discrete GPUs in the ultraportable form-factor where powerful discrete GPUs are generally not possible. "Strix Halo" also goes head on against Apple's M3 Max and M3 Pro processors powering the latest crop of MacBook Pros. It has the same advantages as a single-chip solution, as the M3 Max.

The "Strix Halo" silicon is a chiplet-based processor, although very different from "Fire Range". The "Fire Range" processor is essentially a BGA version of the desktop "Granite Ridge" processor—it's the same combination of one or two "Zen 5" CCDs that talk to a client I/O die, and is meant for performance-thru-enthusiast segment notebooks. "Strix Halo," on the other hand, use the same one or two "Zen 5" CCDs, but with a large SoC die featuring an oversized iGPU, and 256-bit LPDDR5X memory controllers not found on the cIOD. This is key to what AMD is trying to achieve—CPU and graphics performance in the league of the M3 Pro and M3 Max at comparable PCB and power footprints.

Two of AMD's upcoming mobile processors that implement the "Zen 5" microarchitecture, "Strix Point" and "Fire Range," were spotted in shipping manifests. These are prototypes moving between AMD and its OEM partners. The manifest explicitly mentions a "Fire Range" 16-core processor sample with 55 W TDP, another "Fire Range" chip with an 8-core configuration and the same 55 W power; and a trio of "Strix Point" processors with a 28 W power design. Two of these are Ryzen 9 SKUs, and one of them is a Ryzen 7.

VideoCardz has the OPN codes for the samples being moved. The Ryzen 7 "Strix Point" sample bears 100-0000001335. One of the two Ryzen 9 "Strix Point" chips bears 100-000000994. The 16-core "Fire Range" is marked 100-000001028, while the 8-core "Fire Range" is 100-000001029. "Strix Point" will be AMD's most imporant mobile processor silicon, as this will be the one with a "Zen 5" CPU core count relevant to the notebook market, pack an RDNA 3+ iGPU, and that alleged 40 TOPS+ XDNA 2 NPU that can run Microsoft Copilot locally. A step up from this will be "Strix Halo," with a higher CPU core count, a much larger iGPU designed for performance-segment gaming. "Fire Range" is essentially a low Z-height BGA version of the "Granite Ridge" chiplet processor that has up to two "Zen 5" CCDs and an I/O die.

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'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.

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."
