Microsoft has so far neither confirmed nor denied Bloomberg's claims regarding in-house CPU designs.
Enlarge / Microsoft has thus far neither confirmed nor denied Bloomberg’s claims relating to in-house CPU designs.

This afternoon, Bloomberg reported that Microsoft is within the means of creating its personal ARM CPU designs, following within the footsteps of Apple’s M1 cellular CPU and Amazon’s Graviton datacenter CPU.

Bloomberg cites off-record conversations with Microsoft staff who did not need to be named. These sources mentioned that Microsoft is presently creating an ARM processor for datacenter use and exploring the potential of one other for its Floor line of cellular PCs.

Bloomberg’s sources paint the datacenter half as “extra probably” and a Floor half as “potential.” This appears believable, on condition that Microsoft’s chip design unit experiences to the Azure cloud VP, with no direct reporting ties to the Floor division. Microsoft declined to touch upon any particular plans, saying solely that it “[continues] to put money into our personal capabilities in areas like design, manufacturing and instruments, whereas additionally fostering and strengthening partnerships with a variety of chip suppliers.”

Microsoft collaborated with Qualcomm on the SQ1 processor in its Surface Pro X laptops.

Given Microsoft’s deep partnerships with Intel, AMD, and now Qualcomm, this might be a delicate subject for the software program large. With nothing greater than nameless sources to go on, it is a bit of early to make sure what, precisely, Microsoft plans to get out of its silicon analysis. Microsoft may nonetheless be merely co-developing designs with present {hardware} companions like Qualcomm, the best way it already has with the SQ1 and SQ2 processors in Floor Professional X.

If Microsoft does observe Apple’s and Amazon’s lead in designing its personal customized ARM processors, it stands probably to shorten its provide chain and add one other supply of revenue—however relying on scale, fabrication of the brand new designs may show to be a stumbling block.

Even when Bloomberg’s report proves 100% correct, the top result’s more likely to observe Amazon’s lead far more intently than Apple’s. Though Amazon tightened its provide chain by producing its personal Graviton {hardware}, its software program ecosystem stays open—with out strong Linux working system assist, a server’s future in a datacenter could be very poor certainly. Microsoft would face the identical challenges with a datacenter-focused product, and for a similar causes—though the “much less probably” Floor ecosystem can be significantly much less constrained.

We’ve got reached out to Microsoft for remark, and we’ll replace this story with any new data because it arrives.
