Iyo USB Implementers Foramu (USB-IF), iro sangano rinotsigira uye rinokurudzira kutorwa kweUSB (kana Universal Serial Bus) tekinoroji zviyero, ichangobva kuziviswa kupedzwa kweiyo USB 4 standard uye yakasimbisa kuti yakagadzirira kutumirwa kukuru.
Kune izvi, USB 4 maratidziro aburitswa, zvichiratidza kuti tekinoroji inovimba zvakanyanya pane iyo Thunderbolt tsananguro ichangoburwa (vhezheni 3) uye inovimbisa yakafanana yakakwira data mareti (anosvika makumi mana Gb / s). Iyo USB 4 standard inotora mukana weiyo yakasarudzika USB-C chinongedzo uye iri kumashure inoenderana neyamberi USB zviyero, kusanganisira USB 3.2 iyo inopeta kumhanyisa kumhanya kweiyo USB yekubatanidza (kubva 10 Gb / s kusvika 20 Gb / s), USB 2.0 uye Thunderbolt 3.
Brad Saunders, CEO weUSB Promoter Group, akati sangano rake rinongoda kuita zvinhu zvakapfava uye kudzivirira kuwanda kwezvigadzirwa zvakadhonzwa nenhamba dzeshanduro dzinogona kukanganisa vatengi.
Tine USB 4, isu hatidi kuenda munzira 4.0, 4.1, 4.2, "akatsanangura," tinoda kuichengeta iri nyore sezvinobvira.
Kubva 2007, Intel yakabatana mukugadzira iyo Thunderbolt interface neApple, yakagadzirirwa kubatanidza komputa kubatana.
Yechitatu iteration o Kutinhira 3 kwakatangwa muna 2015 uye kunopa kumhanya kwe40 Gb / s . Kubatana pakati peThunderbolt neUSB kwaifungidzirwa, sezvo vhezheni 3, Thunderbolt inoshanda USB-C, saka chiteshi cheThunderbolt 3 chinogona kugamuchira zvishandiso zveUS3.
Iyo USB 3 standard yakaunza kugona kushandisa tambo imwe kubhadharisa mamwe majaira, chinja data uye chiratidzo chevhidhiyo. Asi dzimwe nguva, zvinoenderana nekugadziriswa kwako, zvaigona kuita imwe chete yeaya mashandiro uye nekumhanya zvakanyanya.
Iyo itsva USB 4 yakajairika inovimbisa kugadzirisa izvi nekupa iye Anogashira nekwanisi yekukwira zvakaringana migove yedata kuyerera uye kuratidza.
USB 4 inobvumira 4K kana 8K kuratidzira kuve kwakabatana ne USB, kune daisy cheni dzinoverengeka dzakabatanidzwa USB zvishandiso kune imwechete chiteshi uye inotsigira magetsi emidziyo inoratidza yakakwira simba ye100 watts kuburikidza nemagetsi kuendesa mashandiro.
USB 4 inofanirawo kuve yakabatana chete kune USB Type-C chinongedzo nemapini makumi maviri nemana (pachinzvimbo chechina kana zvipfumbamwe sedzimwe shanduro dzekare dze USB).
Zvimwe zvakakosha zveiyo USB 4 mhinduro inosanganisira:
- Nzira mbiri-nzira uchishandisa aripo USB Type-C tambo uye anosvika makumi mana Gbps mashandiro pamusoro yakasimbiswa 40 Gbps tambo
- Akawanda data uye ekuratidzira mapuroteni zvakanyatso kugovera yakanyanya kuwanda bandwidth
- Kudzokera kumashure kuenderana kweUSB 3.2, USB 2.0, uye Thunderbolt 3
Kubatsirwa chaiko USB yakatarwa 4 ndeyekuti huripo USB Type-C kubatana kuchakwanisa kubata iyo yepamusoro data rwizi, pamwe neyechipiri nzira yekutaurirana.
Kwete izvozvo chete, asi kugona kutyaira Thunderbolt 3 zvishandiso kunounzawo zvakanakira nhaka yeThunderbolt tekinoroji, inoshanda mushe mushe.
Izvo zvakafanana chaizvo kana uchifunga nezve izvo izvo CFExpress vagadziri vakawana nekuwedzera zviripo XQD zvirevo kuti vashandisi varambe vachishandisa zvishandiso zvavo neyakareruka firmware yekuvandudza.
Kufambisa kugamuchirwa kweichi chitsva chiyero, Intel yakaona kuti chizvarwa chayo chinotevera chema x86 processor, kutanga paIqhwa Lake, ichatsigira USB 4 natively uye chiratidzo chako chinangwa chekuburitsa iyo Thunderbolt 3 kududzira nekubvumidza iyo yemahara-yemahara kushandiswa kweiyi tekinoroji.
Yekutanga USB 4-inoenderana zvishandiso haifanire kusvika pamberi pa2020 zvachose uye zvingangoda kushandiswa kweadapter yakatengesa zvakasiyana kushandisa zvakazara kugona kwechiteshi cheUSB 4.
Uye chikamu chakanakisa ndechekuti vashandisi avo vakadzivisa kubhadhara mitengo yakakwira yeThunderbolt 3 kumhanya havangopihwe chete vhezheni inodhura, asi vachakwanisa kuzviita vachishandisa zviripo zveChipiri-C zveyakaenzana-ekupedzisira mashandiro. bhenefiti hombe inofanirwa kutakura USB 4 mune ramangwana re8K.
Iyo USB-IF iri kuronga zvehunyanzvi kudzidziswa pane izvo zvirevo panguva yeUSUS Developer Mazuva ekupedzisira mwedzi uno muSeattle uye kupera kwaNovember muTaipei, Taiwan.
