What isMT/sec

MT/sec, or MegaTransfers per SECond, is a unit of measurement used to determine the speed of buses and channels. Unlike clock frequency, which measures the number of cycles per second, MT/sec reflects the actual speed of data delivered. This rating is often indicated as “MT/s.”

For example, a 400 MHz clock may produce an effective speed of 800 MT/sec when taking into account both the rising and falling edges of the cycle.

Gigatransfers (GT/sec)

In the case of gigatransfers, the “M” in “megatransfers” is replaced by a “G” to indicate gigatransfers. This unit of measurement, represented as GT/sec or GT/s, is used to measure data rates when the clock frequency is doubled.

For instance, if an 800 MHz clock is used, it would generate a data rate of 1.6 GT/sec.

Summary:

– MT/sec (MegaTransfers per SECond) is a measure of the actual delivered speed of buses and channels.
– It is not a measure of clock frequency, but rather reflects the effective speed of data transfer.
– Gigatransfers (GT/sec) replace the “M” in megatransfers, and are used to measure doubled data rates.
– For example, an 800 MHz clock would generate a data rate of 1.6 GT/sec.

FAQ:

Q: How is MT/sec different from clock frequency?

A: While clock frequency measures the number of cycles per second, MT/sec reflects the actual delivered speed of data.

Conclusion:

Understanding MT/sec is crucial when measuring the speed of buses and channels. By considering the actual speed of data transfer rather than just the clock frequency, you can accurately assess the performance of your system.
