About Gigabyte per Second and Gigabit per Second
The gigabyte per second (GB/s) equals 8,000,000,000 bits per second (8 Gbps). It is used for high-end NVMe storage benchmarks, PCIe bandwidth, and GPU memory bandwidth specifications. The gigabit per second (Gbps) equals 1,000,000,000 bits per second (10⁹ bps). It is the standard for fibre-optic internet, data-centre interconnects, and NVMe storage throughput. One Gigabyte per Second equals 8 Gigabit per Second (1 GB-s = 8 Gbps). Gigabyte per Second is used in NVMe Gen 4/5 SSD throughput (5–14 GB/s) and in PCIe 4.0 × 16 bandwidth (~32 GB/s). Gigabit per Second is used in Gigabit and multi-gigabit fibre broadband (1–10 Gbps).
Precision and Rounding:Data transfer rates are almost always quoted in SI decimal prefixes (1 Kbps = 1,000 bps), not binary (1 Kibps = 1,024 bps). Internet service providers universally use SI prefixes. When converting to bytes per second, remember 1 byte = 8 bits exactly. Never round this factor.
