Conversion Formula
Tibit/s = PB/s × 7275.957614
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.
About Tebibits per second
Tebibit per second (Tibit/s) = 2⁴⁰ bit/s (IEC 80000-13). Used in exascale HPC academic papers for memory bandwidth: AMD MI300A APU = 5.3 TB/s ≈ 4.82 TiB/s = 38.6 Tibit/s. NVIDIA H100 HBM3 = 3.35 TB/s ≈ 24.5 Tibit/s. GPU-GPU NVLink 4.0 = 900 GB/s ≈ 6.55 Tibit/s. 1 Tibit/s = 2⁴⁰ bit/s = 128 GiB/s.
