USB4 2.0 Kwikuba kabiri Umuvuduko, Kazoza Hano Hano
Nkuko PC yububiko bwa PC ibishyira mubikorwa40 Gbps USB4, abantu ntibabura kwibaza intego ikurikira yuru rwego rwo guhuza abantu bose izaba irihe? Biragaragara ko ari USB4 2.0, itanga80 Gbpsumurongo wa data muri buri cyerekezo na 60W itanga amashanyarazi (PD) kumuhuza. Amashanyarazi ya USB4 2.0 arashobora kugera kuri 240 W (48 V, 5 A). Buri gihe habaye verisiyo nyinshi za USB, zishobora gusobanurwa zitandukanye. Ariko, hamwe no guhuza buhoro buhoro intera, umubare wa USB verisiyo wagabanutse cyane. Mugihe cya USB4, hasigaye gusa USB-C. Kuki hakiri verisiyo ya 2.0? Ivugurura rinini rya USB4 2.0 ninkunga yaryo yo kohereza amakuru agera kuri 80 Gbps, irenga rwose interineti ya Thunderbolt 4. Reka ducukumbure birambuye.
Mbere, USB4 1.0 isanzwe yatunganijwe hashingiwe ku ikoranabuhanga rya Thunderbolt 3, hamwe n’igipimo ntarengwa cyo kohereza amakuru ya40 Gbps. Verisiyo ya 2.0 yatunganijwe hashingiwe ku bikoresho bishya byubatswe byubaka, byongera igipimo cyo kohereza amakuru kuva ku gipimo cya 40 Gbps kugeza kuri 80 Gbps, hashyirwaho igisenge gishya cy’ibinyabuzima bya USB-C. Twabibutsa ko igipimo gishya cya 80 Gbps gisaba insinga zikora kandi gishobora gushyigikirwa gusa nibicuruzwa byo mu rwego rwo hejuru mugihe kizaza. UwitekaUSB4 2.0ubwubatsi bwamakuru nabwo bwaravuguruwe. Turabikesha uburyo bushya bwububiko bwububiko bushingiye kuburyo bwa kodegisi ya PAM3 hamwe nuburyo bushya bwa 80 Gbps bwibikoresho bifatika, ibikoresho birashobora gukoresha byuzuye kandi byumvikana mugukoresha umurongo. Iri vugurura riragira ingarukaUSB 3.2, Kwerekana amashusho yoherejwe, hamwe na PCI Express yamakuru. Mbere, igipimo ntarengwa cyo kohereza USB 3.2 cyari 20 Gbps (USB3.2 Gen2x2). Munsi yububiko bushya bwamakuru, igipimo cya USB 3.2 kizarenga 20 Gbps kandi kigere kumurongo wo hejuru.
Kubijyanye no guhuza, USB4 2.0 izaba isubira inyuma ihuza USB4 1.0, USB 3.2, na Thunderbolt 3, ntabwo rero bikenewe guhangayikishwa nibibazo bihuza. Byongeye kandi, kwishimira igipimo cyo kohereza amakuru ya 80Gbps, ikintu gishya kandi gikoraUSB-C kugeza USB-Cumugozi wamakuru urasabwa kugirango ugere kuri uyu muvuduko. USB-C yihuta kandi yinjiza USB-C insinga za data ziracyafite umurongo ntarengwa wa 40Gbps. Kugirango usobanure neza ibyiciro byubu bya USB, interineti ya USB yatangiye guhuzwa mukuyita amazina ashingiye kumurongo wohereza. Kurugero, USB4 v2.0 ihuye na USB 80Gbps, USB4 ihuyeUSB 40Gbps, USB 3.2 Gen2x2bihuye na 20Gbps, USB 3.2 Gen2 bihuyeUSB 10Gbps, naUSB 3.2 Itangbihuye na USB 5Gbps, nibindi. Ibirango bipakira, ibirango byimbere, hamwe namakuru ya kabili yamakuru arashobora kuboneka mumashusho akurikira.
Ukwakira 2022, USB-NIBA yari imaze gusohora USB4 verisiyo ya 2.0, ishobora kugera kumikorere ya 80 Gbps. Bifitanye isanoUSB Ubwoko-CnaGutanga ingufu za USB (USB PD)ibisobanuro nabyo byaravuguruwe. Mubisobanuro bya USB4 verisiyo ya 2.0, interineti ya USB Type-C yerekana ibimenyetso nayo irashobora gushyirwaho muburyo butemewe, itanga umuvuduko ntarengwa wa 120 Gbps muburyo bumwe mugihe ugumana umuvuduko wa 40 Gbps mubindi byerekezo. Kugeza ubu, monitor nyinshi zo mu rwego rwo hejuru 4K zihitamo gushyigikira USB-C umurongo umwe uhuza mudasobwa zigendanwa. Nyuma yo gutangiza 80 Gbps USB4 2.0 igisubizo, bimwe4K 144Hzmonitor cyangwa 6K, 8K monitor irashobora guhuza byoroshye na mudasobwa zigendanwa ukoresheje USB-C. Imigaragarire ya 80 Gbps ya USB igumana icyambu cya USB Type-C kugirango yizere ko ishobora guhuza USB 4 Version 1.0, USB 3.2, USB 2.0 na Thunderbolt 3. Byongeye kandi, "80 Gbps USB Type-C Data Cable" yasohotse mu mpera zuyu mwaka ishyigikira verisiyo yihuta ya 80 Gbps mugihe nayo ishyigikira ingufu zishyurwa za 240W 48V / 5A (USB PD EPR). Mudasobwa zigendanwa nshya-biteganijwe ko zizashyirwa ahagaragara mu mpera zuyu mwaka cyangwa umwaka utaha biteganijwe ko zizatangira gushyigikira USB 80 Gbps. Ku ruhande rumwe, PC na monitor zikoresha imbaraga nyinshi cyane zizashobora gukoresha neza ikarita yerekana ishusho; kurundi ruhande, PCIe yo hanze-ikomeye nayo irashobora gukora kubushobozi bwuzuye.
