AMD Ryzen AI MAX 300-series processors, codenamed "Strix Halo," have been on in the news for close to a year now. These mobile processors combine "Zen 5" CPU cores with an oversized iGPU that offers performance rivaling discrete GPUs, with the idea behind these chips being to rival the Apple M3 Pro and M3 Max processors powering MacBook Pros. The "Strix Halo" mobile processor is an MCM that combines one or two "Zen 5" CCDs (some ones featured on "Granite Ridge" desktop processors and "Turin" server processors), with a large SoC die. This die is built either on the 5 nm (TSMC N5) or 4 nm (TSMC N4P) node. It packs a large iGPU based on the RDNA 3.5 graphics architecture, with 40 compute units (CU), and a 50 TOPS-class XDNA 2 NPU carried over from "Strix Point." The memory interface is a 256-bit wide LPDDR5X-8000 for sufficient memory bandwidth for the up to 16 "Zen 5" CPU cores, the 50 TOPS NPU, and the large 40 CU iGPU.

Golden Pig Upgrade leaked what looks like a company slide from a notebook OEM, which reveals the iGPU model names for the various Ryzen AI MAX 300-series SKUs. Leading the pack is the Ryzen AI MAX+ 395. This is a maxed out SKU with a 16-core/32-thread "Zen 5" CPU that uses two CCDs. All 16 cores are full-sized "Zen 5." The CPU has 64 MB of L3 cache (32 MB per CCD), each of the 16 cores has 1 MB of dedicated L2 cache. The iGPU is branded Radeon 8060S, it comes with all 40 CU (2,560 stream processors) enabled, besides 80 AI accelerators, and 40 Ray accelerators. The Ryzen AI MAX 390 is the next processor SKU, it comes with a 12-core/24-thread "Zen 5" CPU. Like the 395, the 390 is a dual-CCD processor, all 12 cores are full-sized "Zen 5." There's 64 MB of L3 cache, and 1 MB of L2 cache per core. The Radeon 8060S graphics solution is the same as the one on the Ryzen AI MAX+ 395, it comes with all 40 CU enabled.

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.

According to Geekerwan, Apple's latest M4 silicon has achieved a remarkable milestone by using liquid nitrogen to chill Apple's M4 iPad Pro. This unconventional approach unlocked great single-core performance, surpassing even the M3 Max and M2 Ultra processors in Geekbench v6 benchmark tests. The setup involved cooling the M4 iPad Pro, equipped with a 3+6 core configuration, using a Kingpin Cooling T-Rex Rev 4 CPU LN2 pot filled with liquid nitrogen. This extreme cooling allowed the M4 processor to operate at an astonishing 4.41 GHz during the benchmark run, resulting in a staggering single-core score of 4,001 points. This score represents a 28% increase over the M3 Max found in the 16-inch MacBook Pro and an impressive 44% improvement over the M2 Ultra powering the Mac Studio.

Notably, the M4's single-core performance is capable of reaching scores in the 3,000s. With liquid nitrogen cooling, it suprases the 4,000-point mark, making this achievement all the more remarkable. While the M4's multi-core performance did not match the lofty expectations set by its single-core power, it still managed to achieve a score of 13,595 points, outperforming both the M3 Max and M2 Ultra, which scored 20,957 and 21,330 points, respectively. This was done on the 3+6 core configuration with three P-cores and six E-cores, which is not the top-end M4 configuration. This shows that with adequate cooling, like MacBooks, the upcoming M4 Pro and M4 Max chips could achieve much higher performance than their predecessors.

As we witness Apple's generational updates of the M series of chips, the highly anticipated SKU of the 3rd generation of Apple M series yet-to-be-announced top-of-the-line M3 Ultra chip is growing speculations from industry insiders. The latest round of reports suggests that the M3 Ultra might step away from its predecessor's design, potentially adopting a monolithic architecture without the UltraFusion interconnect technology. In the past, Apple has relied on a dual-chip design for its Ultra variants, using the UltraFusion interconnect to combine two M series Max chips. For example, the second generation M Ultra chip, M2 Ultra, boasts 134 billion transistors across two 510 mm² chips. However, die-shots of the M3 Max have sparked discussions about the absence of dedicated chip space for the UltraFusion interconnect.

While the absence of visible interconnect space on early die-shots is not conclusive evidence, as seen with the M1 Max not having visible UltraFusion interconnect and still being a part of M1 Ultra with UltraFusion, industry has led the speculation that the M3 Ultra may indeed feature a monolithic design. Considering that the M3 Max has 92 billion transistors and is estimated to have a die size between 600 and 700 mm², going Ultra with these chips may be pushing the manufacturing limit. Considering the maximum die size limit of 848 mm² for the TSMC N3B process used by Apple, there may not be sufficient space for a dual-chip M3 Ultra design. The potential shift to a monolithic design for the M3 Ultra raises questions about how Apple will scale the chip's performance without the UltraFusion interconnect. Competing solutions, such as NVIDIA's Blackwell GPU, use a high-bandwidth C2C interface to connect two 104 billion transistor chips, achieving a bandwidth of 10 TB/s. In comparison, the M2 Ultra's UltraFusion interconnect provided a bandwidth of 2.5 TB/s.

Apple's M-series chips frighten Intel, AMD, and Microsoft like nothing else can, as they have the potential to power MacBooks to grab a sizable share of the notebook market share. This is based squarely on the phenomenal performance/Watt on offer with Apple's chips. A user installed Windows 11 Arm on a virtual machine running on an M2-powered MacBook, opened up CPU-Z (which of course doesn't detect the chip since it's on a VM). They then ran a CPU-Z Bench session for a surprising result—a single-threaded score of 749.5 points, with a multithreaded score of 3822.3 points.

The single-thread score in particular is comparable to Intel's 12th Gen Core "Alder Lake" chips (their "Golden Cove" P-cores); maybe not on the fastest Core i9-12900K, but of the mid-range Core i5 chips, such as the i5-12600. It's able to do this at a fraction of the power and heat output. It is on the backs of this kind of IPC that Apple is building bigger chips such as the M3 Pro and M3 Max, which are able to provide HEDT or workstation-class performance, again, at a fraction of the power.

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."
