notes

Trn2 hardware: trn2.3xlarge = 1 Trainium2, 96 GB; trn2.48xlarge = 16 Trainium2, 1.5 TB HBM3, 46 TB/s; trn2u.48xlarge = same 16 chips but UltraServer-eligible (64 chips across 4 instances over NeuronLink). AWS's own claim: '30-40% better price performance than GPU-based EC2 P5e and P5en instances' - vendor claim, not independently verified here.
