Conversion Formula
GiB = Gibit × 0.125
About Gibibits
A gibibit (Gibit) = 2³⁰ = 1,073,741,824 bits (IEC 80000-13). JEDEC primary capacity unit for DRAM dies: LPDDR5 dies rated at 4/8/16/32 Gibit. HBM2e/HBM3: each die = 16 Gibit = 2 GiB (JEDEC JESD235E); HBM3 12-die stack = 192 Gibit = 24 GiB. NVIDIA H100 SXM 80 GiB = 640 Gibit across 5 HBM3 stacks. 1 Gibit = 2³⁰ bits = 128 MiB.
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.
