Key Takeaways
- USB4.0 zoo li USB 3.2, tsuas yog nrawm dua.
- Thunderbolt 4 yog ib yam nkaus li Thunderbolt 3.0 hais txog kev nrawm thiab muaj peev xwm.
- Koj tseem yuav zaum kawg tuav txoj kab tsis raug.
USB4 thiab Thunderbolt 4 tab tom los rau lub cuab yeej-chaw nres nkoj ze koj, ntxiv lwm txheej txheej ntawm kev xaiv rau qhov tsis meej pem ntawm qhov muaj peev xwm uas yog USB-C.
Txoj xov zoo yog, Thunderbolt 4 yooj yim. Cov xov xwm tsis zoo yog tias USB4 tsis muaj qhov tsis meej pem tsawg. Txawm li cas los xij, tag nrho koj cov khoom qub USB thiab Thunderbolt tseem yuav ua haujlwm thaum ntsaws rau hauv cov chaw nres nkoj tshiab. Tab sis peb tab tom ua ntej ntawm peb tus kheej. Thunderbolt tseem zoo dua, tab sis tsawg dua. Thiab USB4 sai dua tab sis tseem fragmented thiab tseem nyob deb dhau ntawm cov kab uas zoo tib yam.
"Thunderbolt 4 cables tsuas yog hais txog cov kab hluav taws xob thoob ntiaj teb uas koj tuaj yeem tau txais tam sim no. Tau tshaj txhua yam ntawm Thunderbolt, nrog rau txhua qhov tshwj xeeb ntawm USB-C, suav nrog USB 4," hais tias Thunderbolt accessory maker CalDigit ntawm Twitter.
Rollin', hauv Kuv 4.0
thawj qhov tsis meej pem yog nrog cov npe. USB-C yog lub npe ntawm qhov chaw nres nkoj thiab lub ntsaws. USB-3.0, 3.1, 3.2 gen.2, thiab 4.0 yog cov npe ntawm ntau cov qauv USB uas siv tib qhov chaw nres nkoj. Thunderbolt kuj siv tib qhov chaw nres nkoj thiab ntsaws. Thiab ntxiv rau qhov tsis meej pem, tib qhov chaw nres nkoj siv tau los muab lub zog nkaus xwb, tsis muaj ntaub ntawv.
Qhov teeb meem, txawm li cas los xij, tsis yog cov chaw nres nkoj, tab sis cov cables. Ib tug 6-taw cable tsim los them cov xov tooj yuav lossis tsis dhau cov ntaub ntawv, thiab yog tias nws ua, nws yuav luv luv ntawm USB-3.2 spec. Thiab yog tias koj xav siv cov khoom siv Thunderbolt, koj yuav tsum tau siv cov khoom zoo nkauj Thunderbolt-certified cables, uas yog kim. Cov lus qhia Pro: saib rau Thunderbolt li uas suav nrog cov kab hauv lub thawv. Nws tau lees tias ua tau zoo thiab tuaj yeem txuag tau li ntawm $ 50. Nws tsis tsim nyog dag tawm ntawm Thunderbolt cable.
Kuj tseem ceeb yog qhov ntev. Rau ib tug cable muab tag nrho USB 3.2 gen.2, los yog 4 speeds, nws yuav tsum tau luv luv zoo nkauj. Txawm hais tias USB-C fais fab cable tsuas yog xav tau los muab lub zog, yog li nws tuaj yeem ua tau ntev dua.
Hauv luv luv, USB-C thiab Thunderbolt yog qhov zoo, tsuav yog koj muaj lub cable raug. Yog tsis yog, nws hloov mus ua npau suav phem sai sai.
"Qee cov khoom siv tsis tuaj yeem them nrog lub chargers txhawb nqa Kev xa tawm, txawm tias lawv muaj USB-C chaw nres nkoj. Piv txwv li, kuv lub xov tooj OnePlus charger yuav tsis them kuv Google Pixelbook," hluav taws xob engineer Rob Mills hais rau Lifewire ntawm email."Xav txog qhov sib txuas ntawm lub cev USB-C yog tib yam, tsis muaj txoj hauv kev uas tus neeg siv khoom yuav tuaj yeem txiav txim siab qhov no. Ib qho kev daws teeb meem yuav yog kos lub chargers kom meej meej raws li kev txhawb nqa tus qauv fais fab."
4vs4
Cia peb saib qhov sib txawv ntawm Thunderbolt thiab USB. Lawv sib koom tib qhov chaw nres nkoj tab sis muaj peev xwm sib txawv. Thunderbolt yog superset ntawm USB. Yog tias koj muaj qhov chaw nres nkoj Thunderbolt ntawm koj lub computer, koj tuaj yeem ntsaws ib qho USB-C ntaus ntawv rau hauv nws, thiab nws tsuas yog ua haujlwm xwb.
Thunderbolt 4 yeej yog tib yam li Thunderbolt 3 hauv txhua txoj kev, tshwj tsis yog tias nws ntxiv kev ua raws li USB4, qhov Thunderbolt 3.0 tsuas yog lav ua haujlwm nrog USB 3.
Keeb kwm, qhov sib txawv tseem ceeb ntawm TB thiab USB tau ceev thiab bandwidth. Thunderbolt muaj txog li 40 GB / s cov ntaub ntawv xa mus, tab sis tam sim no USB4 tau ntes tau, nrog lub peev xwm los muab tib qhov ceev. Qhov no yog qhov zoo heev rau cov khoom xws li USB-C SSD drives lossis loj USB-C cov lus qhia, tab sis qee lub khoos phis tawj USB4-tshaj yuav tsuas muab 20 GB / s, uas tau tso cai los ntawm 4.0 specs.
Tab sis Thunderbolt tseem muaj ob peb qhov zoo. Ib qho yog tias Thunderbolt tau tsim los ua daisy-chained, yog li koj tuaj yeem ntsaws ib qho Thunderbolt ntaus ntawv rau hauv, hais tias, MacBook Pro thiab tom qab ntawd ntsaws lwm Thunderbolt ntaus ntawv rau thawj tus. Cov cuab yeej thib ob tau txais lub zog thiab tuaj yeem ua haujlwm ntawm qhov nrawm (nyob ntawm seb cov ntaub ntawv ntau npaum li cas thawj Thunderbolt ntaus ntawv siv).
Yog li, Koj Yuav Ua Li Cas Nrog Lawv?
Cov lus teb luv luv yog "txhua yam, tsuas yog sai dua." USB-txuas SSDs tam sim no tuaj yeem khiav ceev li Thunderbolt sawv daws yuav. Lub Thunderbolt 4 chaw nres nkoj yuav tsum muaj peev xwm muab cov array ntawm super-ceev USB4 ports, uas tej zaum yuav xaus rau saturating koj Thunderbolt kev twb kev txuas, tab sis yuav muaj kev lom zem heev txog thaum koj ua.
Thaum kawg, USB4 tsis daws qhov teeb meem loj tshaj plaws ntawm USB-C-qhov yooj yim-rau-siv-txheej cable hom-tab sis nws yuav ua kom txhua yam nrawm dua, uas yog ib qho xov xwm zoo.
