Conversion Formula
GB/s = B/s × 1.000000000e-9
About Bytes per second
Byte per second (B/s) = 8 bit/s. The natural unit for file transfer speeds, disk I/O, and memory bandwidth reported by OS tools and storage benchmarks. ISP 'Mbit/s' ÷ 8 = MB/s download speed: a 100 Mbit/s connection delivers ≈ 12.5 MB/s. USB 2.0 = 60 MB/s; SATA III = 600 MB/s; Thunderbolt 4 = 5,000 MB/s. 1 B/s = 8 bit/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.
