Talk:Gigabit per second


 * Gbit/s
 * Gbyte/s
 * Gibit/s
 * GiB/s

None of these have enough information to be a full article, but clumping them all into the Gbit/s article is not the best, either. Maybe rename to Giga- bit rates or something?

That sounds even worse... — Omegatron 14:42, 21 October 2005 (UTC)

Regarding Removal
Text removed:


 * However, some computer data interfaces are referred to using the phrase "GigaBytes per second"; for example the PCI Express 16x (PCIe) interface is sometimes said to have a transfer rate of "4 GB/s" (meaning 4,000,000,000 [Bytes per second]).


 * The term Gibibit per second (Gibit/s) has been suggested as an alternative (see table), but it is unclear what this value would be used for, as data transfer rates has always been measured in base-10 bits (for example, a "14.4k modem" transmitted at 14,400 bits per second).

Reason given: "This is wrong."

Question: Aside from the typo (KB instead of Bytes), why is it wrong?

Reference:
 * "As an example of recent technology, a Pentium 4 with DDR memory can shift 2.1GB/s across the memory bus. The 8x AGP bus can pass about 2.1GB/s of data a second too."


 * "The PCI Express bus is no longer a single parallel data bus through which all data is routed at a set rate. Rather, an assembly of serial, point-to-point wired, individually clocked ‘lanes’ each consisting of two pairs of data lines carries data upstream and downstream. As the technology goes to market, each of these lanes is capable of a 2.5Gb/s data rate in each direction....The 164-pin X16 slot provides a total usable bandwidth of around 4GB/s in each direction, double the 2.1GB/s bandwidth that the 8x AGP spec boasts. "

Reasons it is wrong:
 * 1) Gibibit is not an alternative for gigabyte.  Gibibyte is.
 * 2) The PCI express measurement is already in decimal billions of bytes.  The unit is gigabyte.  Although gigabyte can vary in meaning, gibibyte means binary billions of bytes always, so the entire example is wrong anyway.  — Omegatron 05:27, 22 October 2005 (UTC)

Transmission speed and throughput
How long does it take to transmit a 1 GB file on a 1 Gigabit per second transmission line? Are there parity bits being sent? --Uncle Ed (talk) 19:25, 20 December 2007 (UTC)
