About the gigabit per second and the gigabyte per second
Gigabits per second is used for fiber internet, Ethernet and Wi-Fi 6 link rates. One Gbps is 1,000 Mbps.
Gigabytes per second is used for NVMe SSD, memory and GPU bandwidth. One GB/s equals 8 Gbps.
One gigabyte per second equals 8 gigabits per second, which makes the gigabyte per second the faster unit of the two.

Gigabits per second to gigabytes per second FAQ
How many gigabytes per second are in one gigabit per second?
One gigabit per second equals exactly 0.125 gigabytes per second. In the other direction, one gigabyte per second equals 8 gigabits per second.
How do I convert gigabits per second to gigabytes per second without a calculator?
convert 4 gigabits per second to gigabytes per second. Using gigabytes per second ← gigabits per second ÷ 8, we get 4 × 0.125 = 0.5 GB/s. To check the result, convert back: 0.5 GB/s ÷ 0.125 = 4 Gbps. For a quick estimate, round the factor to 0.12. Then 4 Gbps is about 0.48 GB/s, compared with the exact 0.5 GB/s (an error of 4%). That is close enough for planning, but use the calculator above when the number matters.
What is gigabit fiber in gigabytes per second?
Gigabit fiber is about 1 gigabits per second, which is 0.125 gigabytes per second. Treat that as an approximate everyday figure rather than an official measurement.
Are the gigabits per second and gigabytes per second the same in every country?
One Gbps is exactly 1,000 Mbps (decimal prefixes are used for network speeds). One GB/s equals exactly 8 Gbps.
