PCI-SIG® Announces Upcoming PCI Express® 6.0 Specification to Reach 64 GT/s

I/O Band­width Dou­bles Every Three Years (Quel­le: Busi­ness Wire)

SANTA CLARA, Calif.–(BUSINESS WIRE)–PCI-SIG Deve­lo­pers Con­fe­rence 2019 – PCI-SIG® today announ­ced that PCI Express® (PCIe®) 6.0 tech­no­lo­gy will dou­ble the data rate to 64 GT/s while main­tai­ning back­wards com­pa­ti­bi­li­ty with pre­vious genera­ti­ons and deli­vering power effi­ci­en­cy and cost-effec­tive per­for­mance. The PCIe 6.0 spe­ci­fi­ca­ti­on is actively tar­ge­ted for release in 2021.

PCIe 6.0 Spe­ci­fi­ca­ti­on Fea­tures

  • Deli­vers 64 GT/s raw bit rate and up to 256 GB/s via x16 con­fi­gu­ra­ti­on
  • Uti­li­zes PAM‑4 (Pul­se Ampli­tu­de Modu­la­ti­on with 4 levels) enco­ding and lever­ages exis­ting 56G PAM‑4 in the indus­try
  • Inclu­des low-laten­cy For­ward Error Cor­rec­tion (FEC) with addi­tio­nal mecha­nisms to impro­ve band­width effi­ci­en­cy
  • Main­tains back­wards com­pa­ti­bi­li­ty with all pre­vious genera­ti­ons of PCIe tech­no­lo­gy

PCI Express tech­no­lo­gy has estab­lished its­elf as a per­va­si­ve I/O tech­no­lo­gy by sustai­ning band­width impro­ve­ments for five genera­ti­ons over two deca­des,” Den­nis Mar­tin, an ana­lyst at Princi­pled Tech­no­lo­gies, said. “With the PCIe 6.0 spe­ci­fi­ca­ti­on, PCI-SIG aims to ans­wer the demands of such hot mar­kets as Arti­fi­ci­al Intel­li­gence, Machi­ne Lear­ning, net­wor­king, com­mu­ni­ca­ti­on sys­tems, sto­rage, High-Per­for­mance Com­pu­ting, and more.”

Con­ti­nuing the trend we set with the PCIe 5.0 spe­ci­fi­ca­ti­on, the PCIe 6.0 spe­ci­fi­ca­ti­on is on a fast time­li­ne,” Al Yanes, PCI-SIG Chair­man and Pre­si­dent, said. “Due to the con­ti­nued com­mit­ment of our mem­ber com­pa­nies, we are on pace to dou­ble the band­width yet again in a time frame that will meet indus­try demand for through­put.”
