About Gibibytes per second
Gibibyte per second (GiB/s) = 2³⁰ B/s (IEC 80000-13). Precision unit for STREAM benchmark and LIKWID memory bandwidth measurements. Intel Xeon Platinum 8380 dual-socket STREAM ≈ 400 GiB/s. RTX 4090 GDDR6X = 1,008 GB/s ≈ 939 GiB/s. PCIe 5.0 ×16 = 64 GB/s ≈ 59.6 GiB/s. AMD EPYC Infinity Fabric (4-socket) ≈ 576 GiB/s cross-die. 1 GiB/s = 2³⁰ B/s = 8 Gibit/s.
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.
