I-Apple ingenye yalezo zinkampani ze-IT ezingavamisile ukuvuma izinqumo ezingalungile futhi kancane kancane ziphenduke zibe ukuhlehla. Lokho , ithimba le-Cupertino elafaka ukusebenza ngo-2016, alikwazi ukubizwa ngokuthi ubunjiniyela noma, ingasaphathwa, ukuhluleka kwezentengiselwano, kodwa iqiniso liwukuthi akuwona wonke umlimi we-poppy, ikakhulukazi phakathi kochwepheshe, abamukele izinguquko ngentshiseko. Amamodeli e-“retina” ka-2013–2015 abizwa ngokufanele ngokuthi uchungechunge lwe-MacBook Pro oluphumelele kakhulu. Baxoshe inqwaba yabasebenzisi kude neWindows nakumaMacs, kodwa u-Apple wabe esedinga ukuthi badele izinto eziningi abazijwayele ukuze bathole ukufinyelela esizukulwaneni esilandelayo sehadiwe. Ngaphezu kwalokho, iMacBook Pro isenenkinga ngokhiye bemvemvane obungakaxazululwa ngokuphelele iminyaka emithathu. Kodwa izikhathi azisafani nakuqala. Kudala, i-win-win bingo yekhibhodi yekhwalithi ephezulu, i-touchpad enethezekile kanye ne-matrix yesikrini esilinganisiwe yayitholakala kuma-Mac kuphela, kodwa manje okungenani amaphuzu amabili kwamathathu angatholakala kubancintisana nabo.
Ngenhlanhla, i-Apple ekugcineni ivumile ukuthi akuzona zonke izimiso ezitholakala kuma-laptops we-2016 okufanele zilwe. Ikhibhodi ngokusobala izoba noshintsho, futhi i-chassis ezacile kakhulu ayenzi okuningi ekupholiseni lapho ama-CPU cores ayisishiyagalombili eyinto evamile kukhompyutha ephathekayo ephezulu. Okokugcina, kunesidingo esinamandla sefomethi yesikrini enkulu kunamayintshi angu-15,4. Abaklami be-MacBook Pro entsha bacabangele zonke lezi zimo futhi, ngaphezu kwalokho, bakwandisa kakhulu ukusebenza komshini okungenzeka kube khona, kuyilapho behlala ngaphakathi kwebanga lentengo elifanayo. Hhayi-ke, silungiselele ukubuyekezwa okuphelele komkhiqizo omusha ngokugcizelela imisebenzi owadalelwa yona - isoftware yobuchwepheshe yokucubungula okuqukethwe okubukwayo.
Izici zobuchwepheshe, ububanzi bokulethwa, amanani
I-MacBook Pro 16 amayintshi (lena yindlela iwebhusayithi yomkhiqizi yolimi lwesiRashiya elibhala ngayo igama lekhompyutha) kwaba umphumela wokuthuthukiswa kwe-bidirectional. Ngakolunye uhlangothi, i-Apple yenze izinguquko ezidlule isikhathi eside ekwakhiweni nasekusetshenzisweni kwezingxenye eziningi zesiteshi sokusebenzela, esizokhuluma ngazo ngokuningiliziwe maduze nje. Ngakolunye uhlangothi, isikhathi sesifikile soshintsho lonyaka lwesisekelo se-silicon, lapho iqembu le-Cupertino ligxile engxenyeni eyodwa eyinhloko - i-GPU. I-AMD, umphakeli okhethekile wama-graphic processors we-Macs, yethule ama-navi chips angu-7-nanometer, futhi u-Apple waphuthuma ukufuna amalungelo okuthenga ama-chips e-Navi 14 asebenza ngokugcwele.
Sibhale kabanzi mayelana nokuthi le GPU ikwazini ekubuyekezeni kwethu ama-accelerator edeskithophu , kodwa ngamafuphi, i-Navi 14 ebhodini elicacile ilingana cishe ne-Radeon RX 580 ethandwayo. Uma kuziwa ezingxenyeni ze-laptop, kufanelekile ukwenza imvume enkulu yejubane eliphansi lewashi, kodwa lokhu kuqhathanisa kakade kwenza kucace ukuthi yini. I-AMD izuze ngokukhipha amakristalu ezingeni eliqhubekayo le-7 nm futhi, vele, isebenzisa ukwakheka kwe-RDNA okusha. Ngaphezu kwalokho, i-MacBook Pro engu-16-intshi okwamanje iyona kuphela i-laptop ethola inguqulo ye-Navi 14 enesethi ephelele yamayunithi ekhompyutha asebenzayo (1536 shader ALUs) ngaphansi kohlobo lweRadeon Pro 5500M. Kukhona ukuthuthukiswa okukhulu kwehluzo ezicacile uma kuqhathaniswa ne-Radeon Pro 560X (inani le-1024 shader ALUs) - ikhadi levidiyo eliyisisekelo lesizukulwane esedlule i-15-inch MacBook Pro - ngisho ngaphandle kokucabangela umehluko wamafrikhwensi wewashi kanye nezinzuzo. ye-RDNA logic ekusebenzeni okuthile. I-Radeon Pro 5500M igqama ngisho nangemuva kwe-Radeon Pro Vega 20 (1280 shader ALUs), i-Apple eyisebenzise ekucushweni okudala. Ngaphezu kwalokho, i-GPU entsha, ngesicelo somthengi, ingahlonyiswa ngamagigabhayithi ayisishiyagalombili enkumbulo yendawo ye-GDDR6 esikhundleni sesine esijwayelekile - futhi uzothola i-Mac ephathwayo enohlelo olungaphansi lwehluzo olusebenza kahle kakhulu lapho amandla aphelele egcinwa khona. i-CPU ingahlangana - cishe i-100 W. Sizothola ukuthi kungani kunje nokuthi yini esivimbela ekuhlomiseni iMacBook Pro nge-analogue ye-Radeon RX 5600M noma i-RX 5700M kamuva nje.

Njengenguqulo yokonga yomgogodla wehluzo, i-MacBook Pro ebuyekeziwe inikeza i-Radeon Pro 5300M - empeleni, ukuyekethisa okuhle kakhulu phakathi kokusebenza okungenzeka kanye nezindleko zomshini. I-chip ye-Navi 14, ngokusho kokucaciswa kwemodeli esezingeni eliphansi, inqanyuliwe isuka ku-1536 kuya ku-1408 shader ALUs egcwele futhi ilahlekelwa ngu-50 MHz kuphela wejubane lewashi elingosomathuba (iwashi layo le-Boost ngu-1205 esikhundleni se-1300 MHz), kodwa kukhona ukubamba okukodwa: akuvumeli ukwandisa inani le-RAM kusuka ku-4 kuye ku-8 GB. Kepha ezinhlelweni ezisebenzayo, okuhloswe ngazo iMacBook Pro (izinhlelo ezifanayo zokuhlela ividiyo), le pharamitha isho okungaphezu kwemidlalo. Ngakolunye uhlangothi, umthengi ngeke alahlekelwe lutho uma ukuhamba kwakhe komsebenzi kungadali umthwalo osindayo ku-GPU. Khona-ke i-chip eqondile izophumula isikhathi esiningi, futhi ihluzo ezihlanganisiwe ze-Intel zizonikeza isixhumi esibonakalayo sohlelo lokusebenza.
Ngokuqondene ne-repertoire yamayunithi okucubungula aphakathi nendawo atholakalayo ku-16-inch MacBook Pro, i-Intel ayikakwazi ukukhama amanye ama-megahertz angamakhulu ambalwa kubuchwepheshe bayo obuvuthiwe (nabuvuthwe ngokweqile) be-14 nm ukuze ithole ama-Core chips esizukulwane se-10. iphakethe le-laptop. I-Apple isakunikeza kuphela ukukhetha phakathi kwezinketho ezimbili ze-CPU eziyisisekelo eziyisithupha kanye ne-flagship eyisishiyagalombili-core Core i9-9980HK. Inzuzo yomkhiqizo omusha ukuthi i-chassis eklanywe kabusha kanye nepholile ivumela ama-algorithms e-auto-overclocking ukuthi afinyelele isivinini esiphezulu sewashi kunakumalaptop akamuva e-Apple angu-15-intshi.
Ijubane elijwayelekile lewashi le-dual-channel DDR4 RAM ku-MacBook Pro manje sekungu-2667 MHz, futhi ivolumu yayo ifinyelela ku-64 GB emangalisayo. Ama-SSD afanayo kubalawuli be-Apple bomklamo wabo asetshenziswa njengesitoreji; ivolumu ayikho ngaphansi kuka-512 GB (ekugcineni!), futhi ngokuzikhethela ifika ku-8 TB. Ekugcineni, ukuhlinzeka idivayisi ngempilo yebhethri abasebenzisi be-Mac abalindele ukuyilindela, i-Apple yashintsha ibhethri engu-83,6 Wh nebhethri elingu-XNUMX-watt. Lokhu akusanakwenzeka, ngaphandle kwalokho ngeke bakuvumele endizeni.
Manje, ngaphambi kokuthi siqale ukuhlola okubonakalayo kwesampula yethu ye-MacBook Pro engu-16-inch, sekuyisikhathi sokumemezela izinombolo ezibaluleke kakhulu. Ngokuphambene nokwesaba kwethu, izintengo zokuthengisa zomkhiqizo omusha esitolo se-inthanethi se-Apple ziqala ku-$2 efanayo nesizukulwane sangaphambilini, futhi yeka ukuthi kungcono kangakanani ukucushwa okuyisisekelo! Kodwa ngohlu oluphelele lokuthuthukiswa kokuzikhethela, izindleko zemoto, ngokwemvelo, zikhuphuka - kufika ku-$ 399, noma ama-ruble angu-6. I-MacBook Pro engu-099 amayintshi ephezulu ibiza cishe ngokufana nedeskithophu yokudlala , esiye sayihlola muva nje, noma kunjalo, ngokukhetha i-Apple, umthengi udela ingxenye enhle yokusebenza (ikakhulukazi maqondana ne-GPU) ngenxa yokuphatheka, ukunethezeka nokugcinwa okubanzi.
Ukubukeka kanye ne-Ergonomics
Ngokuvamile, lapho ihhovisi lokuhlela le-3DNews lithola i-laptop entsha, futhi ngisho nangaphezulu umthwali wezinguquko ezinkulu kuhlu lwamamodeli womkhiqizi owaziwayo, unganikela amagama amaningi ngaphandle kwayo. Enye into i-Apple, isisekelo se-conservatism. Lapha kuyisiko ukwenza ngokohlelo lweminyaka emithathu kuya kwemihlanu, futhi konke ukuthuthukiswa okuphakathi kufihlwe ngaphansi komzimba wemoto. Asazi nokuthi sithini mayelana nomqondo ojwayelekile wokuklama we-16-inch MacBook Pro ongakashiwo emakhasini e-3DNews ekubuyekezweni kwakudala. . Uma ubheka idivayisi ngemuva futhi ingenalo irula ezandleni zakho, awukwazi nje ukuhlukanisa nabanduleli bayo abaseduze.
Kodwa uma ubhekwa ngaphambili, asikho isidingo samathuluzi, ngoba i-Apple ikhulise i-diagonal ye-matrix yesikrini kusuka ku-15,4 kuya kumayintshi angu-16 agcwele, futhi lokhu kubonakala ngokushesha. Nakuba ngezinombolo indawo yesikrini inyuke ngo-7,9% kuphela, umuntu obukele ojwayele izinga elingu-15,4-intshi uzowubona ngokushesha umehluko. Ngakolunye uhlangothi, kusanda kuvela ama-laptops ambalwa ahlangene anamaphaneli angu-17,3-intshi, futhi umkhiqizo omusha we-Apple usondelene nawo. Iphuzu lonke, kunjalo, yi-aspect ratio eyimpumelelo engu-16:10. Izikrini ezilandela izinyathelo zefomethi ye-16:9 HD azinayo nje indawo encane ene-diagonal efanayo, kodwa, njengomthetho, zihambisana nama-laptops ngama-indent aphezulu avela emaphethelweni aphansi nangaphezulu kwesivalo. Futhi okubaluleke kakhulu, isixhumi esibonakalayo sezinhlelo zokusebenza eziningi sisasebenzisa okuqondile ngokuphumelela kakhulu kunezivundlile. Ngokuqondene namafreyimu e-MacBook Pro engu-16-intshi ngokwayo, ayengemakhulu ngokulinganayo ngaphambili. Eqinisweni, i-Apple kwadingeka ikhulise ubukhulu be-laptop kusuka ku-34,93 × 24,07 kuya ku-35,79 × 24,59 cm. lowo ukala 15 × 35,9 cm.
Sizokhuluma ngekhwalithi yesithombe esikrinini se-MacBook Pro engu-16-intshi ngokwehlukana esigabeni sokuhlola sokubuyekezwa, kodwa kufanele sibonge ngokushesha i-Apple nge-anti-reflective ne-oleophobic coating enhle kakhulu. Kodwa-ke, nakuba umenzi kudala elisusile igama elithi Retina egameni lamadivayisi, yilokhu esinakho phambi kwethu: ukuze sigcine ukuminyana kwephikseli okufanayo okungama-220-226 ppi, ukulungiswa okugcwele kwe-matrix izonyuswa isuka ku-2880 × 1800 iye ku-3072 × 1920. Ngakho, yilokho kuphela Akukabi iphaneli ye-4K abanye abakhiqizi abasonakalisa ngayo, futhi umbhalo nezithombe zibukeka zicijile kugridi ye-pixel ecinene. Maye, i-Apple kufanele igxile ekulinganisweni okuphelele kwezinto ezisetshenziswayo futhi ingashintshi le ngxenye ekuhambeni, ukuze abathuthukisi bezinhlelo ezinezici zesithombe ezigqamile bangabi namakhanda angenasidingo.
Ubukhulu be-laptop bukhulile: kunombolo yezinombolo ngokuphawulekayo - ukusuka ku-1,55 cm nesivalo sivaliwe kuya ku-1,62 - kodwa hhayi kakhulu ku-subjective dimension. Kunoma yikuphi, imoto isencane kakhulu kune-"Retina" edumile ka-2012-2015. Kulula ukucabanga ukuthi manje kukhona ngempela indawo ngaphakathi kwecala lomfundi wekhadi. Kodwa futhi, maye, isethi ye-interfaces enezintambo ayizange ibe noshintsho oluncane: umnikazi unezimbobo ezine ze-Thuderbolt 3 kuphela ezihlanganiswe ne-USB 3.1 Gen 2 (kanye ne-mini-jack yehedisethi). Isixhumi ngasinye siqinisekisa ukuphuma okugcwele okungu-40 Gbps, kodwa uma uthembele kulesi sikhombimsebenzisi ukuze uxhumeke ngesivinini esiphezulu kwisitoreji sangaphandle nama-eGPU, kufanele ukukhumbula ukuthi izikhathi ezine i-40 Gbps iyi-arithmetic engalungile uma kubhekwa i-topology ye-Intel mobile. izinhlelo . Sonke isiteshi sokuxhumana phakathi kwe-chipset, iklayenti lalo abalawuli be-Thuderbolt 3, kanye neprosesa emaphakathi isanqunyelwe umkhawulokudonsa webhasi le-DMI 3.0. Eyokugcina ingu-3,93 GB/s, ecishe ilingane nemizila emine ye-PCI Express 3.0. Kodwa ama-monitor amane angaphandle anesinqumo se-4K kanye neziteshi zombala we-10-bit zamukelekile. Ngaphezu kwalokho, i-MacBook Pro entsha ingeyokuqala futhi kuze kube manje ukuphela kwendawo yokusebenza yeselula ye-Apple engasekela ama-monitor amabili e-6K Apple Pro Display XDR ngesikhathi esisodwa, uma kuvela isidingo nethuba elinjalo.
Oh yebo, masingakhohlwa ukuthi esinye sezixhumi ze-Thuderobolt 3 sidinga ukuzinikela ekunikezeni amandla i-laptop, ngakho-ke zintathu kuphela ezizohlala zitholakala ngokukhululekile, futhi lokhu kungaphansi kwe-USB ye-MacBook Pro 2012-2015 (ama-splitters nama-adaptha - basengabangane abakhulu bomlimi wesimanje wepoppy). Ngendlela, i-Apple ikhulise amandla eshaja efakiwe ukusuka ku-87 kuya ku-96 W. Ngokwezindinganiso zamalaptop esimanje, ikakhulukazi ezokudlala, lokhu akukuningi, kodwa iqiniso liwukuthi izintambo nezixhumi ze-Thunderbolt 100 aziklanyelwe amandla angaphezu kuka-3 W. Isimo sakamuva sibeka umkhawulo oqondile hhayi ebhethri kuphela. isivinini sokushaja, kodwa nakunhlanganisela ye-CPU ne-GPU i-Apple eyikhethele i-MacBook Pro entsha. Noma ngabe yimaphi ama-chips ofuna ukuwabona ebhodini lomama lekhompuyutha ephathekayo ye-Apple, gcina le nombolo engqondweni, futhi kuzocaca ngokushesha ukuthi i-Apple ingasebenzisa ini nokuthi yini engeke ikwazi - kungakhathalekile ukuthi luhle kangakanani uhlelo lokupholisa. Ngakolunye uhlangothi, i-Thunderbolt 3 interface ngokwayo inganikeza amandla kumadivayisi angaphandle - 15 W kuwo wonke amachweba amabili. Kungajabulisa ukuthola ukuthi kulesi simo amagajethi angaphandle anikwe amandla yikhompyutha ephathekayo athatha isabelo sawo kusabelomali sama-watt ayi-100, kodwa maye, asizange sibe nalo ithuba elinjalo ngenkathi umkhiqizo omusha usavakashela i-3DNews.
Kodwa i-physics eyanele, sinikeze i-ergonomics. Ushintsho olukhulu ku-MacBook Pro, okungenzeka ukuthi lwafezwa ngobunzima obukhulu ngabantu abaziqhenyayo baseCupertino, luhlobene nokwakhiwa kwekhibhodi. Akuyona imfihlo ukuthi indlela entsha yovemvane, u-Apple aqala ukuyisebenzisa ezinguqulweni eziyekiwe manje ze-intshi eziyi-12 zeMacBook, ngomqondo ongokomfanekiso, ayizange isebenze. Ukunethezeka kwekhibhodi yephrofayili ephansi enohambo olufushane kakhulu kungaxoxwa ngakho. Ngakho-ke, ngokwami, ngokwesibonelo, ngesinye isikhathi ngathola ukuthi ukuthayipha ngokungaboni ngemuva kwesikhathi esifushane sokuzijwayeza kusheshe, futhi okubaluleke kakhulu, okhiye abanyakazi nhlobo ezikhundleni zabo.
Ngesikhathi esifanayo, "uvemvane" lukhala kakhulu lapho lucindezelwa, futhi ezinyangeni ezimbalwa nje ngemva kokuqala kokuthengisa, i-Apple yathola izicelo zokulungiswa nokushintshwa kwamalaptops. Umshini ontekenteke uphenduke waba sengozini enkulu yothuli, futhi le nkinga ayikwazanga ukuxazululwa ngokuphelele ngisho nangemva kokuphindaphindwa kaningana kokuthuthukiswa. Manje indiza yovemvane ekugcineni isiphelile - okungenani kumalaptop ochwepheshe. I-Apple ihlanganise izici ezinhle kakhulu zomklamo omdala nomusha: okhiye be-MacBook Pro engu-16-inch baphakeme, banokuhamba okuphawulekayo okungaba ngu-1 mm, kodwa ngesikhathi esifanayo bacwila emzimbeni ngokulinganayo, ngokufanayo. “uvemvane”. Kuzwakala sengathi kunomehluko phakathi kokuphrinta ku-Retina endala naku-16-inch MacBook Pro, kodwa uvuna umkhiqizo omusha kuphela. Ikhibhodi entsha icishe ifane nokushintshwa kwemishini ephelelwe amandla, futhi ngokuvamile, ukuthayipha umbhalo kuyo kuyintokozo ethintekayo. Njengoba ubona ezithombeni ze-iFixit, ayisekho i-silicone gasket ngaphansi kwezikhiye zokuvikela umshini othulini, futhi lokhu kuwuphawu olukhuthazayo!

Ngesikhathi esifanayo, abaklami be-MacBook Pro benza izinguquko ezincane ku-geometry ehleliwe yekhibhodi. Ngokuya ngendawo ngayinye, okhiye bahlala bebanzi njengamamodeli wangaphambilini kusukela ngo-2016-2019, kodwa umumo “wemicibisholo” ubuyiselwe kuhlamvu oluhlanekezelwe u-T futhi, okubaluleke kakhulu, ukhiye we-Escape wanqanyulwa ku-Touch Bar. . Ngakho-ke, i-Apple isayine ukuthi i-touchpad ayisoze yathatha indawo yokhiye bomzimba ukwenza imisebenzi ejwayelekile kakhulu. Ukusesha isithonjana osifunayo ngamehlo akho ngenkathi uzama ukushintsha ukukhanya kokhiye ongemuva, ukukhanya kwesikrini, noma ivolumu yomsindo akulula neze. Kepha into esemqoka ukuthi siyinqobile i-Escape, futhi ngokubonisa "izinqamuleli" ezinhlelweni ze-macOS ezikwazi ukuphatha iTouch Bar, iphaneli iyinto ewusizo impela.
Ukuze ubhalansise phezulu kwesakhiwo ngakolunye uhlangothi lokhiye we-Escape, i-groove iphinde yasikwa phakathi kwe-Touch Bar nenkinobho yamandla. Ngenhlanhla, lokhu kwakamuva kwakudingeka kucindezelwe ngokomzimba ngaphambili, kodwa manje kulula ukuthola inzwa ye-biometric eyakhelwe kuyo ngokuthinta. Asazi ukuthi yini mayelana nokuphepha, kodwa ngokuvamile kufanele usebenzise isithwebuli ku-macOS, futhi ukwenza kanjalo kuyashesha kakhulu kunokufaka iphasiwedi ende njalo. Kodwa i-touchpad enkulu ene-Force Touch ayizange ibe noshintsho oluncane uma iqhathaniswa nalokho okwakusesizukulwaneni esedlule iMacBook Pro. Futhi ngokufanelekile - wayesevele ephelele.
Ngaphambi kokuvula idivayisi (sizophinda siphendukele osizweni lwe-iFixit), okusele nje ukunaka i-peephole yekhamera yewebhu futhi ulalele ama-acoustics akhelwe ngaphakathi eMacBook Pro. U-Apple namanje akacabangi ukuthi “iwebhu” enesinqumo se-matrix esingaphezu kuka-720p iyadingeka kumalaptop, kodwa lokhu kwanele kukholi yevidiyo. Enye into i-acoustic system, ehlanganisa izipikha eziyisithupha, okuhlanganisa nezishayeli ezimbili ze-low-frequency. Ukufuna umsindo osezingeni eliphezulu kuma-laptop acoustics kuwumsebenzi ongabongi, kodwa kufanele siphinde sinike i-Apple okufanele iyenze: ngosayizi wayo ophansi, iMacBook Pro idlala umculo phezulu nangesisekelo. I-trio yemakrofoni eyakhelwe ngaphakathi, nakuba ingazenzi sengathi iqopha ikhwalithi yesitudiyo, yenza umsebenzi wayo ngokumangalisayo ngonembeza.
Isakhiwo sangaphakathi
Ngaphandle kwephaneli engezansi, ingaphakathi le-MacBook Pro elinesikrini esingu-16-intshi, uma ubheka phezulu, libukeka lifana ncamashi namamodeli angu-15-intshi kusukela ngo-2016–2019. Kodwa uma ubheka eduze, izinguquko eziningi zekhwalithi zizodalulwa. I-Apple ihambe ibanga elide ukuze inikeze ukupholisa okungcono kakhulu kwe-CPU ne-GPU endaweni esesincane kakhulu. Okokuqala, izimbobo ezibanzi zokukhipha umoya zasikwa abalandeli, futhi izinjini zomoya ngokwazo, ngenxa yama-impellers ashintshiwe, kufanele zishayele umoya ongu-28% ngaphezulu kuma-radiator. Indawo yama-radiator nayo inyuke ngo-35% uma iqhathaniswa nesizukulwane sangaphambilini.
Okuwukuphela kokudabukisayo ukuthi ama-memory chips e-GPU awasebenzisi isekethe yepayipi yokushisa evamile, njengoba kwenziwa kwamanye amakhompyutha aphathekayo amageyimu. Zivele zimbozwe ngesembozo sethusi, zicindezelwe emzimbeni we-chip ngokusebenzisa amaphedi ashisayo e-aluminium. Noma ngabe kunjalo, umenzi uthembisa ukuthi uhlelo lokupholisa luyakwazi ukuqeda ama-watts okushisa angu-12 engeziwe. Masiqaphele lesi sitatimende ngaphambi kokuqhubeka nezilinganiso zethu zamandla, izinga lokushisa kanye nesivinini sewashi. Masiqaphele ngokushesha ukuthi ibhethri lapha alikafinyeleli ku-100 Wh egcwele. Eqinisweni, kunama-99,8 awo (yup, balibambile!), kodwa kungenzeka ukuthi ibhethri linqanyulwe kancane ukuze kuqinisekiswe ukuthi liyahambisana nezidingo ze-US Federal Aviation Administration, ebeke umkhawulo we-100 Wh. kumabhethri e-lithium-ion athwalwa emithwalweni yesandla.
Kepha iMacBook Pro ayizange ithole noma yiziphi izinketho zokushintsha izinto ngokungenabuhlungu. Asikho isizathu sokuthi umnikazi wayo agibele ngaphansi kwe-hood yemoto, ngaphandle kokuhlanza uthuli ngezikhathi ezithile. I-RAM ilungile, kodwa i-SSD isathengiswa ngqo ebhodini lomama. Kodwa-ke, noma ngabe bekungenjalo, bekungeke kuthathelwe indawo kalula kanjalo: idrayivu iboshelwe ku-chip yomphathi we-Apple T2, futhi, ngokwesibonelo, ukuthuthukiswa kwayo ezindaweni zokusebenza ze-Mac Pro kungenziwa kuphela ngenkonzo egunyaziwe ye-Apple. isikhungo (kuya Ngenhlanhla, i-Mac Pro isebenza kahle ngama-SSD okungewona awomdabu). Isithombe esifanayo sinamathiselwe enkinobho yamandla ye-T2 ngesikena sezigxivizo zeminwe. Ekugcineni, izingxenye ezimbalwa ze-MacBook Pro zinamathiselwe endaweni noma zibanjwe ama-rivets... Sekukonke, lolu hlelo lulungiselwe ukukhula kangcono, futhi ukuthenga iwaranti enwetshiwe ye-Apple Care iminyaka emithathu egcwele yesevisi kubonakala sengathi umqondo ozwakalayo, ikakhulukazi ekukhanyeni kwentengo yekhompyutha ngokwayo.
