What Memory Crunch? Microsoft AI Roadmap Leak Points To 128GB Builder PCs
We'll start from the bottom: the image shows "Tier 0" Windows PCs as having 8GB of memory. Frankly, at this point, I'm just glad they're starting from 8GB. This isn't really a surprise given the Windows team's recent focus on improving the experience of using Windows on 8GB machines, but considering that the slide dates itself for calendar years 2026-2027, Microsoft clearly expects the RAM shortage to continue through next year. The presence of "Copilot+" is interesting too, given that Microsoft's Surface executive Brett Ostrum recently confirmed that new Surface products would no longer actually be called Copilot+ PCs, and Qualcomm has indicated that it may move away from the terminology as well.
Microsoft describes the bottom two tiers of Copilot+ PCs as being based on "Intel Core Ultra Series 3 & 4, AMD Ryzen AI 400 & 500," and Snapdragon X/X2 hardware. There's nothing too shocking here except that AMD hasn't confirmed Ryzen AI 500 branding for its next-gen "Medusa" processors so this is the first official mention of any such thing, although it comes from Microsoft, not AMD directly. It's likely that Nova Lake, which will reportedly be branded the Core Ultra 4000 series, will also be called "Core Ultra Series 4" by Intel, so that tracks.
The next tier up, 64GB machines, is described as using AMD Ryzen AI Max+ 400 (Gorgon Halo), NVIDIA's "RTX Spark N1X," and "Intel Core Ultra Next". This is pretty interesting, too, because the specific mention of 'RTX Spark N1X' could be seen as a demarcation, an indication that NVIDIA is planning a direct follow-up that will also sport RTX Spark branding. Beyond that, it's not clear why a 64GB machine based on a Nova Lake processor apparently wouldn't qualify for "Local long-running tasks", but that seems to be what Microsoft is implying. Perhaps Razor Lake, said to be the next processor family after Nova Lake, will come with a big AI speed boost.
Moving up once again, it's interesting that Microsoft considers "Builder PCs" to be a large enough category of the market to warrant inclusion in this sort of breakdown. It's clearly talking about high-end RTX Spark laptops, as well as systems like the AMD Ryzen AI Halo development machine. These systems are popular with AI developers to be sure, but their pricing has kept them well out of the realms of regular users, and certainly they don't present a significant portion of the market, though that's admittedly conjecture.
Finally, the last category is the cheekily-named "Supercomputer, " which has a few interesting details, too; Microsoft lists the NVIDIA GB300 DGX Station as an example, and that follows, but it also lists Intel's Crescent Island and simply "AMD Next". The choice to include Crescent Island is an odd one given that everything else listed on the slide is a CPU or a platform, while Crescent Island is the codename for the Intel GPU D-Series accelerators that the blue team detailed last month. They're GPUs, making them fairly distinct even from the GB300 DGX Station, which is a full system platform. And then "AMD Next" is tantalizingly mysterious; AMD has already revealed a high-end competitor to the GB300 DGX in the Threadripper Halo Station, although that machine was only revealed this past September and may not have been announced when this slide was created.
Ultimately there's not much concrete to really glean from the slide, but it's fascinating to see Microsoft's fantasies of people purchasing machines with 128GB of RAM in 2027. It would be great if Microsoft's vision of a future filled with 128GB-plus AI workstations came to pass, but it's difficult to imagine that happening without some pretty substantial changes in the economics of PC memory. Unless the AI market hits a double whammy soon, that's probably not in the cards for 2027.
