Thunderbolt 4: Kodi ndi chiyani komanso momwe zimasiyanirana ndi Bingu 3 ndi USB4

Ngati mumadziwa pang'ono zaukadaulo wazidziwitso, kapena mukawerenga magazini athu, mwina mwamvapo kale za mawonekedwe a Bingu 4. Zowonadi, ndiye wolowa m'malo mwa Bingu 3, koma ziyenera kudziwidwa kuti mungayang'ane. kusiyana kwa liwiro, mawonekedwe a cholumikizira ndi magawo ena molimba kwambiri. Ndiye ngati Bingu 4 likufanana kwambiri ndi Bingu 3 loyambirira, chifukwa chiyani lidapangidwa poyambirira ndipo pali kusiyana kotani? Tiona zimenezi m’nkhani ino.

Kodi Thunderbolt 4 ndi chiyani?

Ukadaulo wa Thunderbolt ndi wa Intel, womwe umagwira ntchito kwambiri popanga mapurosesa. Mapurosesa awa amapezekabe m'makompyuta ena a Apple, ngakhale Apple pang'onopang'ono idzawalowetsa m'malo mwake. Thunderbolt 4 idaperekedwa pamsonkhano wa CES 2020, ndipo monga tafotokozera pamwambapa, poyang'ana koyamba, mungayang'ane zosintha zamitundu yonse pachabe. Maonekedwe ndi mawonekedwe a cholumikizira ndizofanana, zomwe ndi USB-C, ndipo liwiro lalikulu la 40 Gb/s limakhalabe lofanana. Kupatula apo, ndithudi, Thunderbolt 4 imagwiritsabe ntchito chithunzi chofanana cha mphezi. Kusintha kunachitika makamaka pothandizira ntchito zatsopano ndi zinthu zina zazing'ono. Titha kunena kuti Thunderbolt 4 idafinya pang'ono kuchokera kwa omwe adatsogolera.

Kodi pali kusiyana kotani?

Ndikofunikira kwambiri kuti Bingu 4 lizigwirizana kwathunthu ndi USB4. Poyerekeza ndi m'mbuyo mwake, mutha kugwiritsa ntchito kulumikiza zowunikira ziwiri za 4K m'malo mwa imodzi, kapena mutha kulumikiza polojekiti imodzi ya 8K. Oyang'anira apamwamba akuchulukirachulukira, kotero ndikofunikira kuti matekinoloje olumikizirana nawonso azigwirizana ndi nthawi. Malaputopu amathanso kulipiritsidwa kudzera pa Thunderbolt 4, mpaka kutulutsa kokwanira kwa 100 watts. Kutalika kwa chingwe chawonjezeka kufika mamita awiri ndipo kudzera mu basi ya PCIe ndizotheka kupeza liwiro lapamwamba mpaka 32 Gb / s, lomwe likuwonjezeka kawiri kuchokera ku 16 Gb / s yoyambirira. Ubwino wina ndi "kulumikizana" bwino - ndi Bingu limodzi 4 hub, mumatha linanena bungwe madoko anayi owonjezera.

Mwa zina, Thunderbolt 4 ili ndi ntchito yochepetsera kulumikizana kwa mitundu yonse ya zotumphukira kuti ogwiritsa ntchito asakumane ndi kulumikizana pogula chowonjezera chilichonse. Thunderbolt 4 si USB4 yokha - kuphatikiza apo, imabweranso ndi ma protocol a DisplayPort 1.4 otumizira zithunzi, kapena PCIe 4.0. Kuwonjezera pa anthu wamba, makampani ndi mabungwe osiyanasiyana adzayamikiranso izi, chifukwa adzakhala otsimikiza kuti Chalk ambiri adzakhala n'zogwirizana ndi laputopu antchito onse. Pulagi imodzi pachilichonse - imamveka bwino kwambiri. Tiyeni tiyang'ane nazo, ambiri a ife tiri ndi bokosi lodzaza ndi mitundu yonse ya zingwe zolumikizira kunyumba. Koma izi zimasintha pang'onopang'ono, ndipo pang'onopang'ono mukhoza kuyamba kutaya ambiri a iwo.

Kodi ndingadziwe bwanji ngati kompyuta yanga imathandizira Thunderbolt 4?

Ngati muli ndi kompyuta yomwe imathandizira Thunderbolt 3, imathandiziranso Thunderbolt 4 - ndi mosemphanitsa. Zachidziwikire, simungathe kugwiritsa ntchito maubwino onse a Thunderbolt 3 omwe atchulidwa pamwambapa pakompyuta ndi Bingu 4. Thunderbolt monga yotere poyamba idapangidwira makompyuta okhala ndi purosesa ya Intel, koma mwamwayi izi zikusintha ndikufika kwa Bingu 4 - Macs aposachedwa kwambiri okhala ndi Apple Silicon amangothandizira Thunderbolt 3, koma ali ndi chip chothandizira Bingu 4, kotero Apple. mwina amangotchinga ndi mapulogalamu. Komabe, makompyuta omwe ali ndi ma processor a Intel ayenera kukhala ndi mwayi wawung'ono komanso wocheperako akamagwiritsa ntchito Thunderbolt 4. Koma makompyuta amphamvu kwambiri, Bingu 4 ndi gawo la m'badwo wa 11 wa Intel processors, yomwe, mwa zina, kampaniyi yakhala ikugwirizana ndi opanga kope - mwachitsanzo, Lenovo, HP kapena Dell.

Thunderbolt 4 vs USB-C

Ponena za Bingu, kutchulidwa kwake ndikosavuta. Komabe, pankhani ya USB, pali kusiyana pakati pa mtundu wa cholumikizira ndi m'badwo. Ponena za mtundu wa cholumikizira, mwachitsanzo, mawonekedwe ake, titha kulankhula za USB-A, USB-B, USB-C, Mini USB kapena Micro USB. M'badwo womwewo umayikidwa ndi nambala, mwachitsanzo USB 3.2, USB4 ndi ena - zambiri za mutuwu m'nkhani yomwe ndikuyika pansipa. USB4 yaposachedwa yokhala ndi cholumikizira cha USB-C ikadali yofooka kuposa mawonekedwe a Thunderbolt 4, komanso ndi cholumikizira cha USB-C. Ngakhale Thunderbolt 4 imapereka, mwachitsanzo, kusamutsa liwiro mpaka 40 Gb/s ndi kulumikizidwa kwa zowonetsera ziwiri za 4K (kapena chiwonetsero chimodzi cha 8K), USB4 imapereka liwiro lalikulu la 20 Gb/s ndipo simungathe kulumikiza chowonera pogwiritsa ntchito. .

Kukambitsirana kwa nkhaniyo
