Convert Gigabytes per second to Kilobits per second
Convert Gigabytes per second (GB/s) to Kilobits per second (kbit/s) instantly and accurately.
Conversion Formula
kbit/s = GB/s × 8000000
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 Kilobits per second
Kilobit per second (kbit/s) = 1,000 bit/s (SI). The classic unit for narrowband telecoms: dial-up (V.90) = 56 kbit/s; ISDN BRI = 64-128 kbit/s; G.711 VoIP = 64 kbit/s; Opus (WhatsApp, Discord) = 6-510 kbit/s adaptive; Bluetooth Classic = 1,000 kbit/s; Zigbee/Z-Wave = 20-250 kbit/s. 1 kbit/s = 1,000 bit/s = 125 B/s.
