The future AMD 900 series chipsets They promise to significantly shake up the desktop PC market. This is not only due to the new AM5 motherboards, but also to the changes coming to Windows and the DDR5 memory ecosystem. Although much of the information comes from leaks, we can already draw a fairly complete picture of what's to come and what we can expect in terms of both hardware and compatibility with Windows 10 and Windows 11.
Meanwhile, Microsoft and AMD They are working side by side to polish the performance of Ryzen 9000 and future generations In Windows 11, while the Ryzen AI family definitively closes the door on Windows 10 for laptops. All of this is intertwined with the development of new memory formats (CUDIMM and CAMM), a major overhaul of AMD EXPO technology, and the gradual rollout of Windows 11 24H2, which is a game-changer for Zen 2 and beyond.
What do we know about AMD 900 series chipsets for AM5
The big question is what real innovations they will bring. motherboards with AMD 900 series chipsets for socket AM5There are no official technical specifications yet, but leaks point to high-end models such as a possible X970 or X970E that could be shown in the form of prototypes during Computex, starting with brands like Biostar, although it is logical to think that the rest of the manufacturers will want to show something, whether functional or not.
According to leaks, the 900 series chipsets would not be based on a completely new design, but would continue to use the Promontory 21 silicon developed by ASMediaThe same one we already see in the 600 and 800 series. It's a highly scalable and cost-effective chip that can be duplicated on high-end motherboards to multiply connectivity and available lanes. This is already happening with chipsets like the X670, X670E, and X870E.
Although at the pure silicon level there would be almost no changes, that doesn't mean motherboards will be "more of the same." The key is that AMD plans to push new features through the BIOS, expand memory support and enable capabilities that will only be fully available when Zen 6 processors are combined with 900 series chipsets.
Technical updates: BIOS, memory and EXPO 1.2
The main focus of the 900 series will be on the memory subsystem. Future processors AMD Ryzen Olympic Ridge (Zen 6) will integrate a new I/O chip or cIOD (central I/O die), manufactured using a 4 nm process, which includes integrated graphics, input/output management, and a deeply revised memory controller.
That new controller is aimed at higher DDR5 frequencies, lower latency and native compatibility with more advanced memory formats. The idea is that future motherboards with the 900 series chipset will be the ideal vehicle for taking full advantage of this new generation cIOD. This includes significant changes at the BIOS level and in memory profile management.
Currently, the AM5 platform operates relatively comfortably around DDR5-6000 in synchronous mode and values ​​close to DDR5-8000 in asynchronous mode, although this isn't an "official" limit set in stone. With Zen 6 and the new 900 series motherboards, the expectation is to go well beyond these figures, provided the rest of the system (memory and BIOS) supports it.
In this context, the following comes into play AMD EXPO 1.2EXPO 1.2 is the next revision of the company's memory overclocking profile technology. This version is designed to simplify the tuning of high-frequency DDR5 memory, allowing for significant performance increases with just a few clicks in the BIOS or motherboard utilities. Various leaks suggest that EXPO 1.2 will debut with the 900 series motherboards.
Support for CUDIMM and CAMM memory on AM5
One of the great strengths of the new platform will be the CUDIMM and CAMM memory formatsThese standards, which still sound new to many users, are designed to facilitate DDR5 modules capable of operating at very high frequencies with good stability. This all fits perfectly with the goals of Zen 6.
Motherboards with AMD 900 series chipsets will offer native support for CUDIMM and CAMM. One aspect that clearly distinguishes them from most current motherboards. The combination of these formats with EXPO 1.2 and the new memory controller should allow them to easily overcome the frequency barriers currently considered reasonable for home platforms.
AMD wants to reach the level of what it is already achieving Intel with its latest platformsThese technologies allow for very high-frequency memory modules in their official configuration. In fact, models like the Core Ultra 200K Plus already advertise official support for DDR5-7200, compared to DDR5-6400 in the variants without the "Plus" designation. With CUDIMM, CAMM, and EXPO 1.2, the goal is for AM5 to finally catch up in this area.
Another interesting aspect is that Some current motherboards from the 600 and 800 series They will receive new BIOS versions with partial support for EXPO 1.2 and CUDIMM modules. These BIOS updates will allow for the stable installation and use of CUDIMM modules.
For users, this opens the door to a rather practical scenario: Buy CUDIMM modules nowUse them on a current 600/800 series motherboard with reasonable performance and later migrate those same modules to a 900 series chipset motherboard (or a compatible Intel platform) to unlock their full frequency and latency potential without having to reinvest in new memory.
Relationship between 900 series chipsets, Zen 6 and AM5 compatibility
The emerging message is clear. The 900 series of chipsets will be the natural partner for the Zen 6 Olympic Ridge processorsAlthough these processors will be able to work on current AM5 motherboards, full access to the new memory controller features and the most advanced BIOS functions will primarily be available on motherboards with 900 series chipsets.
This means that if we install a future Ryzen Olympic Ridge on an AM5 motherboard from the 600 or 800 series, the processor He will not be able to deploy all his memory-related tricksYes, it will be compatible and will work correctly, but it will fall short of what can be achieved by combining it with a motherboard designed from the ground up for its updated memory controller, CUDIMM/CAMM and EXPO 1.2.
It's worth remembering that the current AM5 chipset family is quite varied. B840 chipset employs Promontory 19While the B650, B650E, B850, and X870 utilize the Promontory 21 chip, the higher-end X670, X670E, and X870E employ two Promontory 21 chips to expand connectivity. This approach will continue with the 900 series, but will be tailored to the needs of Zen 6.
AMD Ryzen 9000, real-world performance and settings in Windows 11
While the future of chipsets is being shaped, the Ryzen 9000 series based on Zen 5 They're already on the market. However, their launch hasn't been as smooth as AMD would have liked. The first tests in games They showed a rather modest performance improvement compared to the Ryzen 7000 series. With increases of only 3-5% on average, far from the 10% that the brand had suggested during Computex 2024.
After analyzing the situation, the company discovered that the main bottleneck was not in silicon, but in how Windows 11 handled certain features of the Zen 5 architectureSpecifically, aspects related to branch prediction units. The surprise came when it was discovered that the way in which the tests were executed significantly influenced the observed performance.
Some media outlets had performed their benchmarks by running the tools on normal user modeOthers, however, did so in administrator mode. There were notable differences. AMD explained that, in administrator mode, Windows was enabling a "correct" branch prediction behavior that was not yet present in the version of Windows 11 used by most reviewers for their tests.
To address the discrepancy between real-world user experience and internal demos, AMD partnered with Microsoft to carry over the "good" predictive behavior of administrator mode to standard user mode in Windows 11. These changes are being incorporated into the Windows 11 24H2 release.
Impact of Windows 11 24H2 on Ryzen 9000, 7000 and 5000
The improvements aren't limited to the Ryzen 9000 series. Research has shown that performance differences due to execution mode This also affects previous Ryzen processors, specifically those based on Zen 3 (Ryzen 5000) and Zen 4 (Ryzen 7000). In other words, a significant number of AMD users will benefit from this collaboration with Microsoft.
Recent tests conducted by specialized media outlets such as Hardware Unboxed show that, with the latest Windows 11 24H2 builds, the The Ryzen 7 9700X can perform up to 11% better in a wide range of 1080p games. Even exceeding the 9% average that AMD had announced in its official presentation. In any case, the improvement varies from title to title.
What's striking is that, when comparing again Ryzen 9000 vs Ryzen 7000 Using the updated Windows 11 24H2 build, the effective performance difference between the two generations becomes much smaller than initially perceived. In other words, Zen 5's relative advantage diminishes when Windows optimizes both architectures equally.
The comparisons have used both Windows 11 23H2 (build 22631)This is the official stable version, like Windows 11 24H2 build 26100, which hasn't yet been released to the general public. With previous 24H2 builds, Ryzen 9000 processors showed performance virtually identical to 23H2 and slightly below what was achieved with certain Linux distributions, such as Ubuntu tuned for specific workloads.
Ryzen AI, Windows 10 and the push towards Windows 11
In parallel with all of the above, AMD is making moves in the field of AI in laptop PCs with the Ryzen AI familyHere, Windows compatibility takes a rather drastic turn: these processors do not support Windows 10. Anyone wanting to enjoy all their capabilities will have to upgrade to Windows 11.
AMD itself has explained that the Ryzen AI 9 HX 370 and Ryzen AI 9 365 They are designed from the ground up to work seamlessly with Windows 11, and especially with features related to Copilot+ and the system's integrated AI acceleration. The architecture and firmware are geared towards this reality. Therefore, it's no surprise that Windows 10 is excluded.
In fact, the new Ryzen AI 300 series only declares compatibility with Windows 11 64-bit and UbuntuIt's clear that the focus is on modern, AI-optimized systems. In practice, this could significantly boost the adoption of Windows 11, which has so far progressed much more slowly than Microsoft would like.
The current market share figures speak for themselves. Windows 10 continues to hover around 70%. of the installed base, while Windows 11 hovers around 26%. end of official support for Windows 10The announcement for October 2025 will already push many users to consider switching, but the arrival of new hardware that directly ignores Windows 10 further accelerates this pressure.
AMD AI platform and software ecosystem
AMD's strategy during this period also involves reinforcing its role as reference platform for AI workloads on PCCombining their next-generation Ryzen processors with product lines PCIe 5.0 The company boasts of being able to simultaneously offer full-performance PCIe 5.0 storage and 16 full PCIe lanes for the discrete graphics card.
This means that, in theory, There is no need to sacrifice the complexity of AI models or GPU bandwidth to achieve maximum disk access speeds. This is crucial when working with large datasets or loading very heavy models from NVMe PCIe 5.0 drives. It's an interesting proposition for both content creators and developers.
Beyond hardware, AMD has spent years refining its ecosystem of software and utilities to get the most out of their CPUs. Tools like Precision Boost Overdrive offer a "one-button" overclocking system that automatically adjusts frequencies and voltages to squeeze out extra performance, while maintaining a certain thermal and electrical safety margin.
For those who want more granular control, there is AMD Ryzen MasterThe official utility for manual and automatic overclocking allows you to change core-by-core frequencies, adjust memory timings, voltages, and other advanced parameters. It's a key tool for enthusiasts who want to fine-tune their configurations, especially on unlocked processors.
The technology itself amd expoThe previously mentioned version 1.2 is part of this ecosystem, enabling certified DDR5 modules to operate at frequencies and latencies well above the JEDEC standard simply by activating a profile in the BIOS. This combination of modern hardware and mature tools should allow users to get the most out of the next generation of AM5 platforms, including those based on 900 series chipsets.
