notes
VERIFIED NEGATIVE, recorded so a later pass does not go looking again. The MI350P board specification table has 'Bus Type: PCIe(R) 5.0 x16' and then goes straight to 'Supported Technologies', listing '4th Gen AMD Infinity Architecture'. There is NO 'Infinity Fabric(TM) Links' row, NO 'Peak Infinity Fabric(TM) Link Bandwidth' row, and NO 'Scale-up' / 'Scale-out' split on this page - unlike the MI350X and MI355X pages of the same CDNA 4 family. The MI350P is the 4-XCD / 1-IOD PCIe card (144 GB HBM3E, 4 TB/s, 128 MB Infinity Cache, up to eight per server), so the CDNA 4 scale-up mesh numbers do not transfer to it: with one IOD it has no IOD-to-IOD path to build the 8-GPU fabric. Any MI350P fabric figure would have to be null plus a note rather than inherited from MI350X.
