Convert Gigabytes per second to Petabytes per second
Convert Gigabytes per second (GB/s) to Petabytes per second (PB/s) instantly and accurately.
Conversion Formula
PB/s = GB/s × 1.000000000e-6
About Gigabytes per second
Gigabyte per second (GB/s) = 10⁹ B/s (SI). Dominant unit for memory bandwidth and GPU interconnects. DRAM: Intel i9-13900K DDR5 = 89.6 GB/s; AMD EPYC Genoa 8-channel = 460.8 GB/s. H100 HBM3 = 3,350 GB/s; RTX 4090 GDDR6X = 1,008 GB/s. PCIe 5.0 ×16 = 128 GB/s. HPC Lustre on Frontier ≈ 5,000 GB/s aggregate. 100 Gbit/s Ethernet = 12.5 GB/s. 1 GB/s = 10⁹ B/s = 8 Gbit/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.
