Inhlangano ye-PCI-SIG ebhekele ukuthuthukiswa kokucaciswa kwe-PCI Express imemezele ukwamukelwa kwezicaciso enguqulweni yokugcina yenguqulo 5.0. Ukuthuthukiswa kwe-PCIe 5.0 kwakuyirekhodi embonini. Imininingwane yathuthukiswa futhi yavunyelwa ezinyangeni eziyi-18 kuphela. I-PCIe 4.0 Imininingwane Ikhishiwe . Manje sesicishe singene ehlobo lika-2019, futhi inguqulo yokugcina ye-PCIe 5.0 isivele ilandwa kuwebhusayithi yenhlangano (yamalungu abhalisiwe). Ohlelweni lwendabuko lwe-bureaucratic, lokhu kuyisimangaliso sokusheshisa. Kungani kwaba khona ukuxhamazela okungaka?
Ukucaciswa kwenguqulo ye-PCIe 4.0 kuthathe iminyaka engu-7 ukuthuthukisa nokusetshenziswa. Ngesikhathi zigunyazwa, azibange zisahlangabezana nezinselele ezintsha: ukufundwa komshini, i-AI kanye neminye imithwalo enzima yokusebenza komkhawulokudonsa ngesikhathi sokushintshisana kwedatha phakathi komprosesa, amasistimu angaphansi kwesitoreji nama-accelerator, okuhlanganisa namakhadi evidiyo. Ukusheshisa kwebhasi ye-PCI Express kwakudingeka ukuze kusekelwe ngokugculisayo imithwalo emisha. Enguqulweni engu-5.0, isivinini sokushintshana saphinde saphindeka kabili uma kuqhathaniswa nesilinganiso sangaphambilini: kusukela ku-gigatransactions engu-16 ngomzuzwana kuya ku-32 gigatransactions ngomzuzwana (ngokwemigqa engu-8).
Ngakho-ke isivinini sokudlulisa ngomugqa ngamunye manje sesicishe sibe ngu-4 GB/s. Ngokucushwa kwakudala kwemigqa engu-16, eyamukelwe ukuxhumana kwamakhadi wevidiyo, ijubane laqala ukufika ku-64 GB/s. Ngenxa yokuthi i-PCI Express isebenza ngemodi ye-duplex egcwele, evumela ukudluliswa kwedatha ngesikhathi esisodwa kuzo zombili izinkomba, umkhawulokudonsa ogcwele webhasi le-PCIe x16 uzofinyelela ku-128 GB/s.
Ukucaciswa kwe-PCIe 5.0 kunikeza ukuhambisana okubuyela emuva namadivayisi ezizukulwane ezedlule, kuze kufike kunguqulo 1.0. Ngaphandle kwalokhu, isixhumi esikhwezayo sithuthukisiwe, nakuba singazange silahlekelwe ukuhambisana okubuyela emuva. Amandla emishini yesixhumi athuthukisiwe, njengoba kuye kwaba nezinguquko ezithile esakhiweni sesignali yesixhumi esibonakalayo ukuze kuqinisekiswe ubuqotho besignali (ukunciphisa umthelela we-crosstalk).
Amadivayisi anebhasi le-PCIe 5.0 ngeke avele emakethe namuhla noma kungazelelwe. Ku-Intel server processors, , ukusekelwa kwe-PCIe 5.0 kulindeleke ngo-2021. Nokho, izinga elisha ngeke lingene kuphela emkhakheni wekhompyutha osebenza kahle kakhulu. Ngokuhamba kwesikhathi, izophinde ifakwe kumakhompyutha womuntu siqu.
