Conversion Formula
PB/s = TiB/s × 0.001099511628
About Tebibytes per second
Tebibyte per second (TiB/s) = 2⁴⁰ B/s (IEC 80000-13). HPC memory scale: AMD MI300A APU = 5.3 TB/s ≈ 4.82 TiB/s; Frontier compute blade (4 GPUs + 1 CPU) ≈ 20 TiB/s aggregate HBM bandwidth. DGX H100 (8 GPUs via NVSwitch) ≈ 6.55 TiB/s GPU-GPU bandwidth. CXL 3.0 rack-scale pooled memory fabric targets low TiB/s. 1 TiB/s = 2⁴⁰ B/s = 8 Tibit/s.
About Petabytes per second
Petabyte per second (PB/s) = 10¹⁵ B/s (SI). Theoretical for single systems. NTT 2024 fibre lab record = 191 TB/s ≈ 0.19 PB/s. Exascale HPC with 10,000 nodes × 10 TB/s memory bandwidth each = 100,000 TB/s = 100 PB/s in aggregate - plausible as a cluster total but not a single link. Global all-data-centre combined write throughput ≈ 1-10 PB/s. 1 PB/s = 10¹⁵ B/s = 8 Pbit/s.
