Convert Gigabytes per second to Bits per second
Convert Gigabytes per second (GB/s) to Bits per second (bit/s) instantly and accurately.
Conversion Formula
bit/s = GB/s × 8000000000
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.
About Bits per second
Bit per second (bit/s) is the fundamental SI data-rate unit - one binary digit transmitted per second. Shannon's channel capacity C = B log₂(1 + S/N) expresses maximum achievable bit/s. Early RS-232 serial links ran at 110-9,600 bit/s; GSM voice uses 13 kbit/s; a coin-flip entropy source produces 1 bit/s per flip. 1 bit/s = 0.125 B/s = 10⁻³ kbit/s.
