USB4 2.0 irushaho kuba umuvuduko inshuro ebyiri, ahazaza ni hano
Nkuko abakora motherboard ya PC bashyira mu bikorwa40 Gbps USB4, abantu ntibashobora kwirinda kwibaza icyo iyi gahunda rusange yo guhuza izaba igamije? Byagaragaye ko ari USB4 2.0, itanga80 Gbpsbandwidth y'amakuru muri buri cyerekezo n'ingufu za 60W (PD) kuri connector. Ingufu za USB4 2.0 zishobora kugera kuri 240 W (48 V, 5 A). Habayeho verisiyo nyinshi za USB, zishobora kuvugwa ko zitandukanye. Ariko, hamwe no guhuzwa buhoro buhoro kwa interfaces, umubare wa verisiyo za USB waragabanutse cyane. Mu gihe cya USB4, niyo yonyine isigaye kuri interface ya USB-C. Kuki hakiri verisiyo ya 2.0? Ivugurura rikomeye rya verisiyo ya USB4 2.0 ni inkunga yayo yo kohereza amakuru kugeza kuri 80 Gbps, irenga burundu interface ya Thunderbolt 4. Reka twige byinshi ku bisobanuro birambuye.
Mbere, uburyo bwa USB4 1.0 bwakozwe hashingiwe ku ikoranabuhanga rya Thunderbolt 3, aho umubare ntarengwa w’amakuru wageraga kuri40 GbpsVerisiyo ya 2.0 yakozwe hashingiwe ku buryo bushya bwo kohereza amakuru, yongera umuvuduko wo kohereza amakuru kuva kuri 40 Gbps kugera kuri 80 Gbps, bishyiraho urwego rushya rw'imikorere kuri sisitemu ya USB-C. Byakagombye kumenyekana ko umuvuduko mushya wa 80 Gbps usaba insinga zikora kandi ushobora gushyigikirwa gusa n'ibindi bikoresho byiza mu gihe kizaza.USB4 2.0Imiterere y'amakuru nayo yavuguruwe. Kubera imiterere mishya y'urwego rw'amakuru ishingiye ku buryo bwo gusimbuza ikimenyetso cya PAM3 hamwe n'insinga nshya ya 80 Gbps, ibikoresho bishobora gukoresha neza bandwidth. Iri vugurura rirushaho kugira ingaruka kuUSB 3.2, kohereza amashusho ya DisplayPort, n'imiyoboro y'amakuru ya PCI Express. Mbere, igipimo ntarengwa cyo kohereza USB 3.2 cyari 20 Gbps (USB3.2 Gen2x2)Muri gahunda nshya y’amakuru, igipimo cya USB 3.2 kizarenga 20 Gbps kandi kigere ku gipimo cyo hejuru.
Ku bijyanye no guhuza, USB4 2.0 izaba ijyanye na USB4 1.0, USB 3.2, na Thunderbolt 3, bityo nta mpamvu yo guhangayikishwa n'ibibazo byo guhuza. Byongeye kandi, kugira ngo wishimire kohereza amakuru kuri 80Gbps, ikoresha uburyo bushya kandi bukoraUSB-C kuva kuri USB-CUmugozi w'amakuru urakenewe kugira ngo ugere kuri uyu muvuduko. Insinga z'amakuru zikoresha USB-C na USB-C zidafite umuvuduko kandi zikora ziracyafite umuvuduko ntarengwa wa 40Gbps. Kugira ngo bisobanuke neza ibyiciro bya USB ubu, uburyo bwo guhuza USB bwatangiye guhuzwa no kuyiha izina hashingiwe ku muvuduko wo kohereza amakuru. Urugero, USB4 v2.0 ihuye na USB 80Gbps, USB4 ihuye naUSB 40Gbps, USB 3.2 Gen2x2ihuye na 20Gbps, USB 3.2 Gen2 ihuye naUSB 10Gbps, naUSB 3.2 Gen1bihuye na USB 5Gbps, nibindi. Ibirango byo gupakira, ibirango byo guhuza, n'ibirango by'insinga z'amakuru biboneka ku ishusho ikurikira.
Mu Ukwakira 2022, USB-IF yari imaze gusohora ibisobanuro bya USB4 verisiyo ya 2.0, ishobora kugera ku muvuduko wa 80 Gbps. Ibi bifitanye isanoUbwoko bwa USB CnaGutanga Ingufu za USB (USB PD)Ibisobanuro nabyo byavuguruwe. Dukurikije ibisobanuro bya USB4 verisiyo ya 2.0, uburyo bwo guhamagara bwa USB Type-C bushobora kandi gushyirwaho mu buryo bungana, butanga umuvuduko ntarengwa wa 120 Gbps mu cyerekezo kimwe mu gihe bugumana umuvuduko wa 40 Gbps mu kindi cyerekezo. Kuri ubu, moniteur nyinshi zo mu rwego rwo hejuru za 4K zihitamo gushyigikira umurongo umwe wa USB-C kuri mudasobwa zigendanwa. Nyuma yo gushyira ahagaragara uburyo bwa 80 Gbps USB4 2.0, zimwe muri zo4K 144HzMoniteri cyangwa moniteri za 6K, 8K zishobora guhuzwa byoroshye na mudasobwa zigendanwa binyuze kuri USB-C. Interface ya USB ya 80 Gbps igumana umuyoboro wa USB Type-C kugira ngo ihuze na USB 4 Verisiyo 1.0, USB 3.2, USB 2.0 na Thunderbolt 3 isanzweho. Byongeye kandi, "80 Gbps USB Type-C Data Cable" yasohotse mu mpera z'uyu mwaka ishyigikira verisiyo yihuta ya 80 Gbps mu gihe inashyigikira imbaraga zo gusharija za 240W 48V/5A (USB PD EPR). Mudasobwa nshya ziteganijwe gushyirwa ahagaragara mu mpera z'uyu mwaka cyangwa umwaka utaha ziteganijwe gutangira gushyigikira USB 80 Gbps. Ku ruhande rumwe, mudasobwa na moniteri zifite imbaraga nyinshi zizashobora gukoresha neza imikorere ya karita y'amashusho; ku rundi ruhande, PCIe yo hanze ishobora gukora neza.
