Theoretically should work on both AMD and Intel
Microsoft has already shown some functions of Windows 11, which they presented formally as exclusives for Copilot+ computers, that is, equipped with processors with NPU units. There were no details about the operation of these functions on other CPUs, but now they have appeared from third-party sources. It looks like everything should work without NPU.
A programmer under the pseudonym Albacore said that his team has made progress in launching the Recall function on an Arm processor system, but it is not Snapdragon X. More precisely, it is far from the most powerful SoC Snapdragon 7c+ Gen 3, which There is no dedicated NPU block at all. The author also reports that theoretically everything should work on regular Intel and AMD CPUs, but so far manufacturers have only received ML model packages for Arm64, so this cannot be verified.
Microsoft itself is in no hurry to explain how all these new features will work on millions of PCs with processors without an NPU. It will be especially interesting to find out whether this will work on fairly old CPUs, where even the iGPU cannot boast of performance.
