Conversion Formula
PB/s = GiB/s × 1.073741824e-6
About Gibibytes per second
Gibibyte per second (GiB/s) = 2³⁰ B/s (IEC 80000-13). Precision unit for STREAM benchmark and LIKWID memory bandwidth measurements. Intel Xeon Platinum 8380 dual-socket STREAM ≈ 400 GiB/s. RTX 4090 GDDR6X = 1,008 GB/s ≈ 939 GiB/s. PCIe 5.0 ×16 = 64 GB/s ≈ 59.6 GiB/s. AMD EPYC Infinity Fabric (4-socket) ≈ 576 GiB/s cross-die. 1 GiB/s = 2³⁰ B/s = 8 Gibit/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.
