Apple is already part of the consortium of manufacturers supporting Draft 3.0 of 802.11ax. The question is whether the silicon already supports 802.11ax which can be accessed through a software upgrade just like Bluetooth 5.0. ) That appears to be the case with this USI module and Bluetooth 4.2 > 5. 802.11a/b/g hardware that included “draft n” features could become 802.11a/b/g/n via a software “enabler”. Thus a quick firmware or driver update can bump up the revision number because some of those features were already supported by the silicon. Apple is the only OEM I am aware of to ship a laptop with support for more than 2 spatial streams. In particular, OFDMA isn’t something that can just be bolted on via a firmware update.Īpple’s use of 3x3:3 Wi-Fi modules in MacBook Pros already makes them 50% faster than any integrated laptop solution from other H, 4 spatial streams are supported under 802.11ac, but usually only by access points. It is incredibly unlikely that this module contains certain functionality necessary to implement the more compelling aspects of 802.11ax. Newer specs often adopt and standardize features that already existed as proprietary extensions to the previous version. There was still only a single SSD controller located in the T2 chip on the logic board. Apple decided to put the NAND flash packages for the iMac Pro on a pair of removable modules, however they were in no way independent drives. RAID 0 in particular ditches the redundant bit and stripes across an array of independent drives purely for increased performance. This is a different concept than RAID though, which employs Redundant Arrays of Independent Drives to increase availability and in some cases performance. It is also likely that the drive can tolerate the failure of individual blocks and pages, or perhaps even whole NAND dies by using parity data. Both the T2 and the NAND flash packages are soldered directly to the logic board. Like most SSD controllers, it uses multiple channels (maybe 8 in this case?) to address the NAND flash dies and increase performance through parallelism. To elaborate on what Dan said, the T2 chip includes Apple’s own NVMe PCIe SSD controller, which they developed in house.
