Convert Gibibits per second to Gibibytes per second
Convert Gibibits per second (Gibit/s) to Gibibytes per second (GiB/s) instantly and accurately.
Conversion Formula
GiB/s = Gibit/s × 0.125
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.
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.
