About Megabits per second
Megabit per second (Mbit/s) = 10⁶ bit/s (SI). Standard consumer broadband unit: ADSL2+ up to 24 Mbit/s; VDSL2 up to 100 Mbit/s; Wi-Fi 6 up to 9,608 Mbit/s; Gigabit Ethernet = 1,000 Mbit/s. Streaming: Netflix 1080p = 5 Mbit/s; 4K HDR = 15-25 Mbit/s; 4K Blu-ray up to 128 Mbit/s. ISP 100 Mbit/s ≈ 12.5 MB/s download. 1 Mbit/s = 10⁶ bit/s = 125 KB/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.
