Conversion Formula
GiB = Pibit × 131072
About Pebibits
A pebibit (Pibit) = 2⁵⁰ bits (IEC 80000-13). Intel LA57 5-level paging extends virtual addressing to 57 bits = 128 PiB = 1 Pibit of byte-addressable virtual memory space per process. The Frontier supercomputer (ORNL, 2022) has ≈700 PiB = 5,600 Pibit of total Lustre storage. AMD EPYC Milan-X supports up to 52-bit physical addresses (4 PiB). 1 Pibit = 2⁵⁰ bits = 128 TiB.
About Gibibytes
A gibibyte (GiB) = 2³⁰ = 1,073,741,824 bytes (IEC 80000-13). The source of the 'storage discrepancy': a '500 GB' drive contains 500×10⁹ bytes ≈ 465.66 GiB as shown by Windows. RAM is manufactured in exact powers of 2: 4/8/16/32/64 GiB. GPU VRAM: RTX 4090 = 24 GiB; H100 = 80 GiB; MI300X = 192 GiB HBM3. Kubernetes memory limits use Gi suffixes. 1 GiB = 2³⁰ bytes = 1,024 MiB.
