iFixit Teardown Guide Puts Spotlight on Apple Vision Pro Logic Board

iFixit has finally posted photos of the Apple Vision Pro's inner bits, following on from the release of a video teardown (uploaded last week)—the American e-commerce and how-to website spent plenty of hours exploring the expensive mixed reality headset's "creepy" features, before breaking seals and deconstructing the device's highly complex interior. The iFixit teardown team have often complained about Apple computer products being notoriously difficult to deal with—the Vision Pro is no exception, but they eventually managed to isolate the headset's logic board. The onboard M2 octa-core chipset is identified as a APL1109/339S01081E part, while its assistant R1 sensor co-processor sports an APL1W08/339S01186 identifier. Micron has supplied 8 GB of LPDDR5 SDRAM memory (MT62F1G64D8WT-031 XT), and Kioxia has Apple covered with its K5A4RC2097 256 GB NAND flash.

Tech experts have spent time poring over iFixit's latest set of snaps, as laid out in their teardown guide—one such enthusiast, Yining Karl Li, posted an intriguing Apple Vision Pro Logic Board observation to social media: "There's this interesting shot of the main logic board (in Step 1). The R1 chip (in the red box) has interesting lines all over it dividing the surface into sub-boxes. Is the R1 chip using a chiplet design?" A small debate erupted from this quick inspection—one commenter believes that the co-processor is not all that fancy: "(it is) likely sporting low-latency fan-out memory," citing the presence of very faint horizontal and vertical lines. As pointed out by Wccftech, Li also presented a chiplet design example (for comparison purposes)—a close-up shot of Intel's Ponte Vecchio Xe-HPC GPU. The lines are a lot more pronounced on Team Blue's chip design.

Heh, whenever I see iFixit mentioned, JayzTwoCents' in-video ad pops up to my mind:

So what's the HW BoM cost?

A $1500-1600 guesstimate from last May.
I got a chance to mess with one and it's much better built as well compared to the PC, mobile, and even the PS VR (which is the only gaming focused one that's actually pretty good). It's still got to come down in price and it will eventually. They'll release a cheaper one just as they did with their high end monitor.

I wonder how many people are going to get run over wearing this.

I wonder what those 3 Apple branded "power management" IC's are REALLY doing? When you combine the size and pin count, they must be doing a lot of something...

I'm sure it won't be long before the first reports come in. There are a lot of rich nerds deliberately using these in public, as they have become a nerd status symbol overnight!
