Sirin'i inokwira: PCI Express 5.0 yakatarwa inogamuchirwa

Sangano rePCI-SIG rinotarisira kuvandudzwa kwePCI Express zvakatemwa yakazivisa kugamuchirwa kwezvakatemwa mushanduro yekupedzisira yevhezheni 5.0. Iko kuvandudzwa kwePCIe 5.0 yaive rekodhi yeindasitiri. Izvo zvakatemwa zvakagadziridzwa uye zvakabvumidzwa mumwedzi 18 chete. PCIe 4.0 Zvinyorwa Zvakaburitswa zhizha 2017. Isu tave kuda kupinda muzhizha ra2019, uye iyo yekupedzisira vhezheni yePCIe 5.0 inogona kutotorwa kubva kuwebhusaiti yesangano (yenhengo dzakanyoreswa). Kune yechinyakare bureaucratic system, ichi chishamiso chekuwedzera. Nei pakanga paine kumhanya kwakadaro?

Iyo PCIe 4.0 vhezheni yakatarwa yakatora makore manomwe kugadzira uye kutora. Nenguva yavakatenderwa, ivo havachasangana nematambudziko matsva: kudzidza muchina, AI uye mamwe bandwidth-yakanyanya kurema basa panguva yekutsinhana kwedata pakati pe processor, masisitimu ekuchengetedza uye accelerators, kusanganisira makadhi evhidhiyo. Yakakosha PCI Express bhazi kukwidziridzwa kwaidiwa kutsigira zvinogutsa mabasa matsva. Mushanduro 7, iyo yekutsinhana kukurumidza yakapetwa kaviri zvakare kana ichienzaniswa neyekare chiyero: kubva 5.0 gigatransactions pasekondi kusvika 16 gigatransactions pasekondi (maererano ne32 mitsetse).

Iyo yekumhanyisa yekumhanyisa pamutsetse saka ikozvino inenge 4 GB/s. Nekugadziriswa kwekare kwemitsara gumi nematanhatu, yakagamuchirwa yevhidhiyo kadhi interfaces, kumhanya kwakatanga kusvika 16 GB / s. Nekuti PCI Express inoshanda mune yakazara duplex modhi, ichibvumira panguva imwe chete kuendesa data mumativi ese, iyo yakazara bandwidth yePCIe x64 bhazi ichasvika 16 GB/s.

PCIe 5.0 zvakatemwa zvinopa kuseri kuenderana nemidziyo yezvizvarwa zvakapfuura, kusvika kushanduro 1.0. Pasinei neizvi, iyo inosungirirwa yekubatanidza yakagadziridzwa, kunyangwe isina kurasikirwa nekudzokera kumashure. Simba remagetsi rekubatanidza rakagadziridzwa, sezvakaita dzimwe shanduko kune chimiro chechiratidzo chechimiro chekuona kutendeseka kwechiratidzo (kuderedza kukanganisa kwe crosstalk).

Midziyo ine PCIe 5.0 bhazi haizooneke pamusika nhasi kana kamwe kamwe. Mune Intel server processors, somuenzaniso, PCIe 5.0 rutsigiro inotarisirwa muna 2021. Nekudaro, iyo chiyero chitsva haingopindire iyo yepamusoro-inoshanda komputa chikamu. Nekufamba kwenguva, ichaiswawo mumakomputa emunhu.
