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 Mebibits per second

Mebibit per second (Mibit/s) = 2²⁰ = 1,048,576 bit/s (IEC 80000-13). Used in FPGA-to-memory interface specs and JEDEC memory bus timing documents where bit rates are derived from 2ⁿ clock frequencies. A 100 MHz 8-bit parallel bus = 800 Mibit/s. Contrasted with Mbit/s (= 10⁶ bit/s). 1 Mibit/s = 1,048,576 bit/s ≈ 131 KB/s.
