I-Thunderbolt 4: Iyini nokuthi ihluke kanjani ku-Thunderbolt 3 ne-USB4

Uma okungenani ujwayelene nobuchwepheshe bolwazi, noma uma ufunda umagazini wethu, kungenzeka ukuthi usuzwile kakade mayelana nesixhumi esibonakalayo se-Thunderbolt 4. Yiqiniso, lo ngumlandeli we-Thunderbolt 3, kodwa kufanele kuqashelwe ukuthi uzobheka. ngomehluko ngokuya ngesivinini, ukubukeka kwesixhumi namanye amapharamitha kanzima kakhulu. Ngakho-ke uma i-Thunderbolt 4 ifana kakhulu ne-Thunderbolt 3 yasekuqaleni, kungani yadalwa kwasekuqaleni futhi imuphi umehluko wangempela? Sizobheka lokho kulesi sihloko.

Iyini i-Thunderbolt 4?

Ubuchwepheshe be-Thunderbolt bungeka-Intel, esebenza ngokuyinhloko ekukhiqizeni ama-processor. Lawa maphrosesa asatholakala kwamanye amakhompyutha akwa-Apple, nakuba i-Apple izowashintsha kancane kancane ifake awayo. I-Thunderbolt 4 yethulwe engqungqutheleni ye-CES 2020, futhi njengoba kushiwo ngenhla, ekuqaleni, ubungabheka zonke izinhlobo zezinguquko ngeze. Ukubukeka nokuma kwesixhumi kuyafana, okuyi-USB-C, futhi isivinini esiphezulu esingu-40 Gb/s sisafana. Ngaphandle kwalokho, vele, i-Thunderbolt 4 isasebenzisa isithonjana sombani esifanayo. Izinguquko zenzeke ikakhulukazi ekusekelweni kwemisebenzi emisha nezinye izinto ezincane. Kungashiwo ukuthi i-Thunderbolt 4 incinde kancane kancane kweyandulelayo.

Uyini umehluko?

Kubaluleke kakhulu ukuthi i-Thunderbolt 4 ihambisane ngokugcwele ne-USB4. Uma iqhathaniswa neyandulelayo, ungayisebenzisa ukuze uxhume kufika kumamonitha amabili e-4K esikhundleni seyodwa, noma ungaxhuma imonitha eyodwa ye-8K. Iziqaphi zokuxazulula okuphezulu ziya ngokuya zithandwa, ngakho-ke kuyadingeka ukuthi ubuchwepheshe bokuxhumana ngokwabo buhambisane nezikhathi. Amakhompyutha aphathekayo angashajwa ngeThunderbolt 4, kuze kufike ekuphumeni okuphezulu kwama-watts ayi-100. Ubude bekhebula obukhulu bunyusiwe baba ngamamitha amabili futhi ngebhasi le-PCIe kungenzeka ukuthola isivinini esifinyelela ku-32 Gb/s, okuwukunyuka okuphindwe kabili ukusuka ku-16 Gb/s yasekuqaleni. Enye inzuzo "ukuxhumana" okungcono - ngehabhu elilodwa le-Thunderbolt 4, uyakwazi ukukhipha amachweba amane angeziwe.

Phakathi kwezinye izinto, i-Thunderbolt 4 inomsebenzi wokwenza lula ukuxhumana kwazo zonke izinhlobo zama-peripherals ukuze abasebenzisi bangabhekana nokuxhuma lapho bethenga into ngayinye. I-Thunderbolt 4 akuyona i-USB4 kuphela - ngaphezu kwayo, futhi iza nemigomo ye-DisplayPort 1.4 yokudlulisa isithombe, noma nge-PCIe 4.0. Ngaphezu kwabantu abajwayelekile, izinkampani kanye nezinhlangano ezahlukahlukene zizokwazisa lokhu, njengoba zizoqiniseka ukuthi izesekeli eziningi zizohambisana nawo wonke amalaptop abasebenzi. Ipulaki eyodwa yayo yonke into - izwakala ipholile ngempela. Ake sibhekane nakho, iningi lethu linebhokisi eligcwele zonke izinhlobo zezintambo zokuxhuma ekhaya. Kodwa lokhu ekugcineni kushintsha kancane kancane, futhi ungaqala kancane ukulahla eziningi zazo.

Ngazi kanjani ukuthi ikhompyutha yami isekela i-Thunderbolt 4?

Uma unekhompyutha esekela i-Thunderbolt 3, iphinde isekele i-Thunderbolt 4 - futhi ngokuphambene nalokho. Yebo, ngeke ukwazi ukusebenzisa zonke izinzuzo ze-Thunderbolt 3 ezisohlwini olungenhla kukhompuyutha ene-Thunderbolt 4. I-Thunderbolt njengoba injalo ekuqaleni yayihloselwe kuphela amakhompyutha ane-Intel processor, kodwa ngenhlanhla lokhu kuyashintsha ngokufika kwe-Thunderbolt 4 - ama-Mac akamuva ane-Apple Silicon asasekela kuphela i-Thunderbolt 3, kodwa ane-chip yokusekela i-Thunderbolt 4, ngakho-ke i-Apple mhlawumbe uyivimba kuphela nge-software. Noma kunjalo, amakhompyutha anama-Intel processors kufanele abe nenzuzo encane futhi engasho lutho uma usebenzisa i-Thunderbolt 4. Ngokuqondene namakhompyutha anamandla kakhulu, i-Thunderbolt 4 iyingxenye yesizukulwane se-11 se-Intel processors, lapho, phakathi kwezinye izinto, le nkampani ibambisene nabakhiqizi abahamba phambili be-notebook - isibonelo, i-Lenovo, i-HP noma i-Dell.

I-Thunderbolt 4 vs USB-C

Ngokuqondene ne-Thunderbolt, ukuqokwa kulula kakhulu. Nokho, endabeni ye-USB, kunomehluko phakathi kohlobo lwesixhumi nesizukulwane. Mayelana nohlobo lwesixhumi, okungukuthi ukubonakala kwaso nje, singakhuluma nge-USB-A, USB-B, USB-C, Mini USB noma Micro USB. Isizukulwane ngokwaso sibe sesimakwa ngenombolo, okungukuthi isibonelo i-USB 3.2, USB4 nezinye - okwengeziwe ngalesi sihloko esihlokweni engisinamathisela ngezansi. I-USB4 yakamuva enesixhumanisi se-USB-C isebuthakathaka kunesixhumi esibonakalayo se-Thunderbolt 4, futhi inesixhumi se-USB-C. Ngenkathi i-Thunderbolt 4 inikeza, isibonelo, isivinini sokudlulisa esingafika ku-40 Gb/s kanye nokuxhumeka kwezibonisi ezimbili ze-4K (noma isibonisi esisodwa se-8K), i-USB4 inikeza isivinini sokudlulisa esiphezulu esingu-20 Gb/s futhi awukwazi ukuxhuma isibonisi usebenzisa sona. .
