Convert Petabits per second to Gigabytes per second
Convert Petabits per second (Pbit/s) to Gigabytes per second (GB/s) instantly and accurately.
Conversion Formula
GB/s = Pbit/s × 125000
About Petabits per second
Petabit per second (Pbit/s) = 10¹⁵ bit/s (SI). Research-scale only: NTT (2024) achieved 1.53 Pbit/s over a single fibre using space + wavelength division multiplexing. The combined peak of the world's largest internet exchange points (DE-CIX, AMS-IX) is multi-Tbit/s. Global IP traffic ≈ 1.8 Pbit/s sustained average in 2030 forecast. 1 Pbit/s = 10¹⁵ bit/s = 125 TB/s.
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.
