Um... where are the RAM slots? Are they soldered on?
Yes, because if the article is to believed, the desktop kit comes with GDDR6 memory, which you can't find in loose modules. And this makes sense because if it really is based off defective Xbox Series X APUs, then they come natively with a GDDR6 controller, not a standard DDR4 controller.
Which would make for some interesting memory benchmarks.
Another curiosity is the support for USB 3.2 Gen 2. The Xbox Series X and S only support Gen 1. This will become a notable issue as more and more giant games are released that require the limited internal/slot SSD to be played. The necessity for moving games to and from external USB drives will be a given for anybody with a decent sized library that likes day to day variety in their play. The performance of the USB ports makes a big difference in how convenient this is. Sony is supporting Gen 2 on the PS5, though they initially didn't allow for games to moved offline to USB storage. They've since fixed that glaring omission in the firmware. Now I'm wondering if the Series x/s can be upgrade via firmware for Gen 2 support or with a minor hardware revision. The latter would be annoying to owners of the 7 million or so units sold so far between the two models but an improvement for the larger pool of machines that can be expected to be sold in the next few years.
According to Microsoft's provided block diagram of the Xbox Series X, USB support is provided on a separate chip because the APU itself doesn't have any USB controllers built in:
So no, the Series X can't get USB 3.2 Gen 2 support with a firmware update.
