Umbutho we-PCI-SIG ojongene nokuphuhliswa kweenkcukacha ze-PCI Express ubhengeze ukwamkelwa kweenkcukacha kwinguqu yokugqibela ye-5.0. Ukuphuhliswa kwePCIe 5.0 yayiyirekhodi yoshishino. Iinkcukacha zaphuhliswa kwaye zamkelwa kwisithuba nje seenyanga ezili-18. PCIe 4.0 iinkcukacha ziphumile . Ngoku sele sisondele kwihlobo lika-2019, kwaye inguqulelo yokugqibela yePCIe 5.0 sele ikhutshiwe kwiwebhusayithi yombutho (kumalungu abhalisiweyo). Kwinkqubo yesiqhelo ye-bureaucratic, lo ngummangaliso wokukhawulezisa. Kwakutheni ukuze kubekho ukungxama okungaka?
Inkcazo yenguqulo ye-PCIe 4.0 ithathe iminyaka eyi-7 ukuphuhlisa nokwamkelwa. Ngethuba lokuvunywa kwabo, abazange baphinde bahlangabezane nemingeni emitsha: ukufundwa komatshini, i-AI kunye neminye imithwalo yemisebenzi ye-bandwidth-intensive ngexesha lokutshintshiselana kwedatha phakathi kweprosesa, i-subsystems yokugcina kunye ne-accelerators, kubandakanywa namakhadi evidiyo. Ukukhawuleziswa kwebhasi ye-PCI Express ebalulekileyo yayifuneka ukuxhasa ngokwanelisayo umthwalo omtsha wokusebenza. Kwinguqulo ye-5.0, isantya sotshintshiselwano saphinda saphindwa kabini xa kuthelekiswa nomgangatho wangaphambili: ukusuka kwi-gigatransactions ye-16 ngesibini ukuya kwi-32 gigatransactions ngesibini (ngokwemigqaliselo ye-8).
Isantya sokudlulisa ngomgca ngamnye ngoku ngoku malunga ne-4 GB / s. Ukucwangciswa kweklasikhi yemigca ye-16, eyamkelwe kwi-interfaces yekhadi levidiyo, isantya saqala ukufikelela kwi-64 GB / s. Ngenxa yokuba i-PCI Express isebenza kwimodi epheleleyo ye-duplex, evumela ukuhanjiswa kwedatha ngaxeshanye kumacala omabini, i-bandwidth epheleleyo yebhasi ye-PCIe x16 iya kufikelela kwi-128 GB / s.
Iimpawu zePCIe 5.0 zibonelela ngasemva ukuhambelana nezixhobo zezizukulwana zangaphambili, ukuya kuthi ga kwinguqulo ye-1.0. Ngaphandle koku, isinxibelelanisi esixhomayo siphuculwe, nangona singakhange siphulukane nokuhambelana ngasemva. Amandla omatshini wokudibanisa aphuculwe, njengoko kukho utshintsho oluthile kwisakhiwo somqondiso we-interface ukuqinisekisa ukunyaniseka komqondiso (ukunciphisa impembelelo ye-crosstalk).
Izixhobo ezinebhasi ye-PCIe 5.0 aziyi kubonakala kwimarike namhlanje okanye ngokukhawuleza. Kwi-Intel server processors, , Inkxaso ye-PCIe 5.0 ilindeleke kwi-2021. Nangona kunjalo, umgangatho omtsha awuyi kungena kuphela kwicandelo lekhompyutheni elisebenza kakuhle. Ngokuhamba kwexesha, iya kufakwa nakwiikhompyutha zomntu.
