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 Gibibits per second
Gibibit per second (Gibit/s) = 2³⁰ = 1,073,741,824 bit/s (IEC 80000-13). Preferred over Gbit/s in JEDEC DDR memory bandwidth specs: DDR5-4800 single channel = 38,400 MB/s = 307,200 Mbit/s ≈ 293 Gibit/s. HBM3 per stack = 819 Gbit/s ≈ 763 Gibit/s. LINPACK and memory benchmark literature may use Gibit/s for precision. 1 Gibit/s = 2³⁰ bit/s = 128 MiB/s.
