Gigabyte per Second (GB/s)
A gigabyte per second is 10⁹ bytes each second, 8 Gbit/s. NVMe SSDs read at 3.5–7 GB/s and memory bandwidth runs to tens of GB/s.
Symbol: GB/s
Quantity: data transfer rate (bandwidth)
SI relation: 1 GB/s = 8000000000 bps (exact)
Derivation: 1 GB/s = 10⁹ B/s = 8 Gbit/s.
Exact: yes, by definition
Typical uses
- NVMe SSD speeds
- Memory and PCIe bandwidth
- GPU and server throughput
