Convert Zettabits per second to Gigabytes per second
Convert Zettabits per second (Zbit/s) to Gigabytes per second (GB/s) instantly and accurately.
Conversion Formula
GB/s = Zbit/s × 125000000000
About Zettabits per second
Zettabit per second (Zbit/s) = 10²¹ bit/s (SI). Entirely theoretical. The entire global internet traffic in all of 2024 (≈40 Zbit) could be transferred in ≈40 seconds at 1 Zbit/s. The full electromagnetic spectrum (radio to gamma, ≈10³⁰ Hz bandwidth) at Shannon capacity still cannot sustain 1 Zbit/s with any known physical medium. 1 Zbit/s = 10²¹ bit/s = 125 EB/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.
