Convert Terabytes per second to Gigabytes per second
Convert Terabytes per second (TB/s) to Gigabytes per second (GB/s) instantly and accurately.
Conversion Formula
GB/s = TB/s × 1000
About Terabytes per second
Terabyte per second (TB/s) = 10¹² B/s (SI). Achieved in HPC memory fabrics: NVIDIA GB200 NVL72 rack-scale system ≈ 130 TB/s aggregate memory bandwidth. SK Hynix HBM-PIM ≈ 1.2 TB/s per HBM stack. NTT 2024 fibre record = 1.53 Pbit/s = 191 TB/s. Multi-socket server PCIe 6.0 aggregate approaching TB/s scale. 1 TB/s = 10¹² B/s = 8 Tbit/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.
