PCI Express 4.0 for 2015

The announcement was made by Al Yanes, President of the PCI SIG during a meeting with the Semi Accurate publication.

PCI SIG announced at the end of June that it formed a group for the research for the fourth generation of the PCI Express standard. That team included members of companies such as Intel, AMD, Hewlett-Packard and IBM.

For the organization PCI-SIG (Peripheral Component Interconnect Special Interest Group) in charge of the creation of the PCI standards, the final PCIe 4.0 standard will be ready by 2014 for the manufacturers to create products this year to be released in 2015.

It is said that it will double the efficiency of the PCIe 3.0 turning from 8 to 16 GT/s (gigatransfers per second on PCI data bus). We are talking about speeds per lane, and we must consider that each PCIe bus usually has up to 16 lanes (16x).

In addition to the increase of transfer speeds of the standard, developers will also have to reduce the latencies of the PCIe interface Gen 4, apart from remain alert to other aspects of the standard, such as, for example, error fixing, a deeper juxtaposition or the notification and control of errors.
