Convert Exabits per second to Gigabytes per second
Convert Exabits per second (Ebit/s) to Gigabytes per second (GB/s) instantly and accurately.
Conversion Formula
GB/s = Ebit/s × 125000000
About Exabits per second
Exabit per second (Ebit/s) = 10¹⁸ bit/s (SI). Theoretical: Shannon limit for a single-mode fibre over 50 THz optical bandwidth ≈ 100 Pbit/s - still ~10,000× below 1 Ebit/s. Reaching 1 Ebit/s would require ≈1 million parallel fibres each at 1 Pbit/s. Global internet backbone installed capacity in 2024 ≈ 5-10 Pbit/s. 1 Ebit/s = 10¹⁸ bit/s = 125 PB/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.
