Convert Megabytes per second to Gigabytes per second
Convert Megabytes per second (MB/s) to Gigabytes per second (GB/s) instantly and accurately.
Conversion Formula
GB/s = MB/s × 0.001
About Megabytes per second
Megabyte per second (MB/s) = 10⁶ B/s (SI). Standard for storage benchmarks and USB speeds. NVMe SSDs: Samsung 990 Pro (PCIe 4.0) = 7,450 MB/s; PCIe 5.0 drives = 10,000 MB/s; SATA HDD = 80-220 MB/s. USB 3.2 Gen 1 = 625 MB/s; USB4 Gen 3 = 5,000 MB/s. Memory: DDR5-4800 dual-channel = 76,800 MB/s. A 4K RAW cinema camera generates ≈1,000 MB/s. 1 MB/s = 10⁶ B/s = 8 Mbit/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.
