ON MAY 20, a week ago, Microsoft announced its new line of CoPilot PCs led by new versions of its Surface computers.
Microsoft's Surface computers are not just a product, they are the company's concept machines, luxury devices that are supposed to inspire design cues among the many partners that build computers to run its software.
The biggest cue Microsoft offered in these new computers was an apparent commitment to ARM-based processors from Qualcomm, specifically its new SnapDragon X CPU, Hexagon NPU and Adreno GPU.
Microsoft is making lots of noise about the AI capabilities of its new Surface computers and the system design it hopes will be taken up by its hardware manufacturing partners.
Acer, ASUS, Dell, HP, Lenovo and Samsung have announced new computers using the new chip designs that run Windows on ARM, which is now a product in wide release.
The new computers are also a signal from Microsoft that it is willing to support other processors for mainstream use. Since the company was founded, its OS and apps have been almost exclusively coded for chips manufactured by Intel.
But it's not the first time that Intel has looked to another manufacturer of CPUs for a product. In 2005, the company launched its new Xbox line of gaming consoles with the PowerPC chip developed by Apple, Motorola and IBM, which had previously been used by Apple as its second-generation processors between 1994 and 2006.
In 2012, Microsoft took its first stab at an ARM-based Surface computer, the ill-fated Surface RT which ran a severely pruned version of Windows on underpowered hardware. (The company would eventually write off US$900 million after it failed.)
Intel's chips use what's known as CISC, or complex instruction set computing. Chipsets based on ARM computing designs are described as RISC, or reduced instruction set computing.
The differences between the two, even in simplified form, are deeply technical, but the way the two chip architectures process the instructions that are written into code is different.
Those differences have blurred over time, but RISC chips offer a more elegant way of executing code on hardware delivering more performance while drawing less power.
It isn't surprising then for Microsoft to openly compare its new Surface systems with Apple's popular M3 MacBook Air.
"(The ARM Surface computers) are up to 20x more powerful and up to 100x as efficient for running AI workloads and deliver industry-leading AI acceleration," Yusuf Mehdi, Microsoft's consumer chief marketing officer, wrote on Microsoft's announcement blog.
"They outperform Apple's MacBook Air 15' by up to 58 per cent in sustained multithreaded performance, while delivering all-day battery life."
So where do these new Windows computers fit into Microsoft's PC strategy?
They reaffirm the company's commitment to Windows everywhere, crafting a uniform and predictable interface for its core operatin
