Transfers per second

Source: Wikipedia, the free encyclopedia.

In computer technology, transfers per second and its more common secondary terms gigatransfers per second (abbreviated as GT/s) and megatransfers per second (MT/s) are informal language that refer to the number of operations transferring data that occur in each second in some given

billion
transfers per second.

Units

These terms alone do not specify the

GiB/s. The bit rate
for this example is 64 Gbit/s (8 × 8 × 109 bit/s).

The formula for a data transfer rate is: Channel width (bits/transfer) × transfers/second = bits/second.

Expanding the width of a channel, for example that between a CPU and a

throughput without requiring an increase in the channel's operating frequency (measured in transfers per second). This is analogous to increasing throughput by increasing bandwidth but leaving latency
unchanged.

The units usually refer to the "effective" number of transfers, or transfers perceived from "outside" of a system or component, as opposed to the internal speed or rate of the clock of the system. One example is a

where data is transferred on both the rising and falling edge of the clock signal. If its internal clock runs at 100 MHz, then the effective rate is 200 MT/s, because there are 100 million rising edges per second and 100 million falling edges per second of a clock signal running at 100 MHz.

Buses like

Infinity Fabric
operate at the gigatransfer rate.

The choice of the symbol T for transfer conflicts with the International System of Units, in which T is the symbol for the tesla, a unit of magnetic flux density (so "megatesla per second" (MT/s) would be a reasonable unit to describe the rate of a rapidly changing magnetic field, such as in a pulsed field magnet or kicker magnet).
