Convert Petabytes per second to Gibibits per second
Convert Petabytes per second (PB/s) to Gibibits per second (Gibit/s) instantly and accurately.
Conversion Formula
Gibit/s = PB/s × 7450580.597
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 Gibibits per second
Gibibit per second (Gibit/s) = 2³⁰ = 1,073,741,824 bit/s (IEC 80000-13). Preferred over Gbit/s in JEDEC DDR memory bandwidth specs: DDR5-4800 single channel = 38,400 MB/s = 307,200 Mbit/s ≈ 293 Gibit/s. HBM3 per stack = 819 Gbit/s ≈ 763 Gibit/s. LINPACK and memory benchmark literature may use Gibit/s for precision. 1 Gibit/s = 2³⁰ bit/s = 128 MiB/s.
