Michal Ždanský Raws li qhov xav tau, MacBooks tshiab tau txais qhov tshiab-ceev Thunderbolt (LightPeak) chaw nres nkoj, thiab lwm lub khoos phis tawj Apple yuav ua raws. Hauv tsab xov xwm no, kuv xav ua tib zoo saib ntawm vaunted Thunderbolt, ob qho tib si los ntawm kev siv tshuab thiab kev xav ntawm kev xav.
Thunderbolt nyob rau hauv lub iav magnifying
Txawm hais tias LightPeak tham feem ntau txog kev sib kis ntawm fiber ntau, Thunderbolt, uas tau tshwm sim hauv MacBook Pro, yog xim hlau, piv txwv li kev sib kis yog raws li electrons, tsis yog photons. Qhov no txhais tau hais tias peb tsuas tuaj yeem npau suav txog qhov theoretical ceev ntawm 100 Gb / s rau tam sim no, nrog rau txog 100 m cables. Ntawm qhov tod tes, ua tsaug rau cov khoom siv hluav taws xob, Thunderbolt tseem tuaj yeem them cov khoom siv hluav taws xob mus txog 10 W, thiab tus nqi yuav qis dua vim tsis muaj optics. Kuv xav tias yav tom ntej kho qhov muag version tseem yuav muaj cov khoom siv hlau tsuas yog them nyiaj xwb.
Thunderbolt siv PCI Express 2.0 interface los ntawm kev sib txuas lus. Nws muaj peev xwm mus txog 16 Gb / s. PCI Express tam sim no tsuas yog siv los ntawm cov ntawv teev lus. Yog li, Thunderbolt dhau los ua ib yam ntawm PCI nthuav qhia sab nraud, thiab yav tom ntej peb kuj tseem tuaj yeem cia siab tias cov npav sab nraud txuas nrog Intel lub interface tshiab.
Thunderbolt, tsawg kawg raws li tau hais los ntawm Apple, tau ua ke nrog mini DisplayPort hauv kev kho dua 1.1 thiab tso cai rov qab sib raug zoo nrog nws. Yog li yog tias koj txuas, piv txwv li, Apple Cinema Display ntawm Thunderbolt, nws yuav ua haujlwm ib txwm, txawm tias Apple saib tseem tsis tau muaj Thunderbolt.
Dab tsi yog qhov nthuav heev yog qhov tshiab interface yog ob-channel thiab bidirectional. Cov kwj ntawm cov ntaub ntawv tuaj yeem ua haujlwm ua ke, ua rau tag nrho cov ntaub ntawv hloov mus txog 40 Gb / s, tab sis nrog qhov tseeb tias qhov siab tshaj plaws ceev ntawm ib channel hauv ib qho kev taw qhia tseem yog 10 Gb / s. Yog li nws zoo rau dab tsi? Piv txwv li, koj tuaj yeem sib pauv cov ntaub ntawv ntawm ob lub cuab yeej tib lub sijhawm ntawm qhov siab tshaj plaws tau nrawm thaum xa cov duab mus rau ib qho kev saib sab nraud.
Tsis tas li ntawd, Thunderbolt muaj peev xwm hu ua "daisy chaining", uas yog ib txoj hauv kev ntawm chaining li. Nyob rau hauv txoj kev no, koj tuaj yeem txuas mus txog 6 cov khoom siv nrog Thunderbolt chaw nres nkoj uas yuav ua haujlwm raws li cov khoom siv nkag / tso tawm thiab mus txog 2 tus saib nrog DisplayPort tom kawg ntawm cov saw hlau (nrog ob lub saib nws yuav yog 5 cov khoom siv), uas ua. tsis tas yuav muaj Thunderbolt. Tsis tas li ntawd, Thunderbolt muaj qhov qeeb qeeb (8 nanoseconds) thiab kev hloov pauv hloov pauv tau yooj yim, uas yog qhov tseem ceeb tsis yog rau daisy chaining nkaus xwb.
USB 3.0 killer?
Thunderbolt feem ntau hem qhov qeeb-tsim USB 3.0. Lub USB tshiab muaj kev hloov ceev txog li 5 Gb / s, piv txwv li ib nrab lub peev xwm ntawm Thunderbolt. Tab sis dab tsi USB tsis muab yog tej yam xws li ntau-channel kev sib txuas lus, daisy chaining, thiab kuv tsis txawm xav tias yuav siv rau A / V composite tso zis. USB 3.0 yog li no theej cov kwv tij nrawm dua ntawm yav dhau los dual version.
USB 3.0 tuaj yeem txuas ntxiv mus rau lub motherboard ntawm PCI-e, hmoov tsis Thunderbolt tsis tso cai rau qhov no. Nws yuav tsum tau siv ncaj qha rau ntawm lub motherboard, yog li yog tias koj tab tom txiav txim siab ntxiv Thunderbolt rau koj lub PC, kuv yuav tsum poob siab rau koj. Txawm li cas los xij, peb tuaj yeem cia siab tias Intel thiab thaum kawg lwm cov tuam txhab motherboard pib siv nws hauv cov khoom tshiab.
Undoubtedly, Thunderbolt yog tus sib tw ncaj qha ntawm USB tshiab, thiab yuav muaj kev sib ntaus sib tua hnyav ntawm lawv. USB twb tau sib ntaus sib tua zoo sib xws nrog rau qhov tshiab FireWire interface. Txog hnub no, FireWire tau dhau los ua qhov teeb meem tsawg, thaum USB yuav luag txhua qhov chaw. Txawm hais tias Firewire muaj kev hloov pauv ntau dua, nws tau cuam tshuam los ntawm kev them nyiaj tso cai, thaum lub USB daim ntawv tso cai tsis pub dawb (tshwj tsis yog rau qhov tshwj xeeb high-speed USB version). Txawm li cas los xij, Thunderbolt tau kawm los ntawm qhov ua yuam kev no thiab yuav tsum tsis muaj daim ntawv tso cai them nqi los ntawm cov tuam txhab thib peb.
Yog li yog tias Thunderbolt yeej nws qhov chaw hauv lub hnub, cov lus nug yuav yog seb USB 3.0 puas yuav xav tau txhua. Kev sib raug zoo nrog USB tseem tuaj yeem ua tau nrog Thunderbolt los ntawm kev txo qis, thiab tam sim no USB 2.0 yuav txaus rau cov ntaub ntawv hloov pauv ntawm flash drive. Yog li USB tshiab yuav muaj lub sijhawm nyuaj, thiab hauv ob peb xyoos Thunderbolt yuav raug tshem tawm tag nrho. Tsis tas li ntawd, 2 tus neeg muaj zog heev sawv tom qab Thunderbolt - Intel thiab Apple.
Nws yuav zoo rau dab tsi?
Yog tias peb tuaj yeem tham txog lub sijhawm tam sim no, ces Thunderbolt tsis yog siv hauv kev xyaum, feem ntau yog vim tsis muaj cov khoom siv nrog qhov kev sib tshuam no. Nws tsis yog qhov xav tsis thoob, Apple yog thawj tus tshaj tawm tshwj xeeb tshaj tawm Thunderbolt hauv nws phau ntawv sau, ntxiv rau, qhov tshwj xeeb tau lees paub rau ntau lub hlis, yam tsawg kawg ntawm kev koom ua ke ntawm motherboards.
Txawm li cas los xij, lwm cov tuam txhab lag luam nyuam qhuav pib flirt nrog Thunderbolt. Western Digital, Kev cog lus a LaCie tau tshaj tawm txog kev tsim cov ntaub ntawv khaws cia thiab lwm yam khoom siv nrog Intel tshiab interface, thiab nws tuaj yeem cia siab tias lwm cov players muaj zog xws li Seagate, Samsung, A-Cov Ntaub Ntawv thiab ntau ntxiv yuav sai sai no, raws li ob peb yuav xav tsis tawm ntawm nthwv dej tshiab uas lawv tuaj yeem caij nyob rau hauv qhov chaw. Apple tau dhau los ua ib lub cim ntawm qhov tseeb hais txog kev siv cov thev naus laus zis tshiab, thiab feem ntau ntawm cov thev naus laus zis uas nws tau siv tau dhau los ua qhov tseem ceeb hauv qee lub sijhawm, coj los ntawm thawj USB.
Peb tuaj yeem cia siab tias Apple yuav xav siv Thunderbolt hauv feem ntau ntawm nws cov khoom. Kev hloov kho tshiab ntawm Lub Sijhawm Capsule yog yuav luag 100% qhov tseeb, ib yam li iMacs tshiab thiab lwm lub khoos phis tawj Apple uas yuav raug qhia yav tom ntej. Kev xa tawm tuaj yeem xav tau rau cov khoom siv iOS no, qhov twg Thunderbolt yuav hloov cov khoom txuas uas twb muaj lawm. Nws tsis tuaj yeem hais meej tias nws yuav yog xyoo no, tab sis kuv yuav muab kuv txhais tes rau hauv qhov hluav taws kub vim tias iPad 3 thiab iPhone 6 yuav tsis zam nws ntxiv lawm.
Yog tias Thunderbolt tiag tiag ua tiav hauv kev sib tsoo ntawm I / O cov khoom siv, ces peb tuaj yeem cia siab tias yuav muaj dej nyab ntawm cov khoom lag luam nrog qhov kev sib txuas no thaum kawg ntawm lub xyoo. Thunderbolt yog ntau yam uas nws tuaj yeem hloov tau tag nrho cov khoom qub qub nrog rau cov kev sib txuas niaj hnub xws li HDMI, DVI thiab DisplayPort yam tsis tau ntsais qhov muag. Thaum kawg, tsis muaj laj thawj vim li cas nws tsis tuaj yeem hloov LAN classic. Txhua yam tsuas yog nyob ntawm kev txhawb nqa ntawm cov tuam txhab tsim khoom thiab lawv txoj kev ntseeg siab hauv lub interface tshiab thiab, qhov kawg tab sis tsis kawg, ntawm kev ntseeg siab ntawm cov neeg siv khoom.
Ouch. Zoo, qhov ntawd yog qhov tso dag :)
Tsis muaj leej twg yuav hais li ntawd, tsis yog WOOOW...!!! Kuv zoo siab tos txais rau lub sijhawm uas kuv yuav muaj mini-pidi Mabook Air qhov twg nws yuav siv tau zoo thaum mus ncig thiab thaum kuv mus txog tsev thiab txuas mus rau Cinema tshiab thiab nws yuav muaj cov duab muaj zog thiab lub suab kaw lus. siv rau hauv nws thiab kuv tsis paub dab tsi ntxiv thiab dheev nws yuav dhau los ua lub tshuab muaj zog rau kev xyaum txhua yam. Qhov ntawd yuav zoo heev, tus tswv. Los yog ntsiav tshuaj thiab xinesmas kuj yuav zoo :-)
