David Hanak I-MacBook Pro entsha engu-15 ″ ene-8-core processor isigcine ingenile ezandleni zababuyekezi abafuna ukwazi, futhi ngaphezu kokulinganisa ukusebenza okungaphekiwe, singathola ukuthi iMacBook isebenza kanjani futhi ngokuya ngokusebenza. Ikakhulukazi endaweni yokupholisa, kwakukhona into enkulu eyayingaziwa emoyeni, ngoba iMacBook Pros yayinenkinga yokupholisa ngisho ne-6-core chip ye-Intel enamandla kakhulu (nokushisa) ye-Intel, okwakudingeka i-Apple iyixazulule ngonyaka odlule ngokulungisa isofthiwe.
Kungaba njalo okuthakaselayo
I-Core i9 eyisihluthulelo esiyisithupha kumamodeli wangonyaka odlule ekuqaleni yahlushwa ukupholisa okubuthakathaka kwe-MacBook Pro, ngenxa yokuthi iphrosesa ayikwazanga ukusebenza kumaza abonisiwe. Cishe ngokushesha ngemva kokuqala komthwalo, kwakudingeka ifakwe ngaphansi kwewashi, futhi ekugcineni ukusebenza kwayo kwakusezingeni elifanayo njengezinhlobonhlobo ze-4-core. I-Apple yagcina ixazulule inkinga ngokushintsha isofthiwe nokushuna, kodwa umphumela usaxoxisana. Ukufaka i-chip enamandla nakakhulu ngaleyo ndlela kwavusa ukungabaza okusemthethweni.
Abahleli beseva Appleinsider basebenzise ibhentshimakhi edumile ye-Cinebench R20 lapho kuhlolwa. Nokho, esikhundleni sokugijima okukodwa kwebhentshimakhi, baqhube ukuhlolwa ngokuqhubekayo ngokulandelana ukuze balingise umthwalo wesikhathi eside kuphrosesa.
Ngokushesha ngemva kokuqala ukuhlolwa kokuqala, amaza okucubungula akhuphukela kumanani akhangisiwe wezinga le-Turbo Boost, okungukuthi 5 GHz. Nokho, cishe ngokushesha ngemva kwalokho, izinzwa zokushisa zephrosesa zirekhodwa zifinyelela kumadigri ayi-100, okuwumkhawulo (ophakeme kakhulu uma kuqhathaniswa) lapho i-chip izofakwa ngaphansi kwewashi ngenjongo yokunciphisa izinga lokushisa lokusebenza - lokho okubizwa ngokuthi i-thermal throttling. Kodwa-ke, esikhundleni sokwehlisa imvamisa ewashini lesisekelo le-2,4 GHz, iMacBook ikwazile ukugcina amaza okusebenza e-chip phakathi kuka-2,9 no-3 GHz, okuwumphumela ohlonipheke kakhulu.
Ngesikhathi sokuhlolwa kwesikhathi eside, imvamisa yazinza ezungeze i-3 GHz eshiwo ngenhla, lapho izinga lokushisa le-chip lalisezingeni lama-degree angama-94, osemngceleni wezimo zokusebenza eziphephile zesikhathi eside (ukushisa okuphezulu kakhulu kancane kancane. bhubhisa ama-chips, ikakhulukazi uma kukhulunywa ngomthwalo wesikhathi eside).
Isimo esibucayi sokupholisa ama-processor anamandla kakhulu ku-MacBook Pro sinezizathu ezimbalwa. I-Apple ayinacala ngeyokuqala, ngoba ukwakhiwa kwe-chassis yalesi sizukulwane kwenzeka ngesikhathi esithile ngo-2015, lapho i-Intel imemezela ukufika kwezizukulwane ezintsha zama-chips azoba namandla kakhulu futhi ngesikhathi esifanayo ukonga kakhulu kunangaphambili. isizukulwane. Kodwa-ke, lokhu akwenzekanga futhi i-Intel yaguqula inani le-TDP laba ikhalenda eliphukayo, okwathi ekugcineni lathathwa abakhiqizi bekhompuyutha ephathekayo, ababenokupholisa kakade kwase kukhulu kakhulu futhi kulungisiwe.
Kodwa-ke, i-Apple futhi kufanele isolwe ngesistimu yokupholisa ecashile eyakhele iMacBooks yayo. Imithetho yefiziksi ayinakugwenywa, yize i-Apple ikwazile ukupholisa amaphrosesa aphezulu kahle esizukulwaneni samanje seMacBook Pros.
Ngasikhathi sinye, akekho owaziyo ngempela ukuthi i-Apple ikwenze kanjani. Ngokuya nge-hardware, akubanga khona izinguquko ekupholiseni noma ukuma kwe-chassis. Isistimu yokupholisa isafana, kanye ne-fan ne-radiator. Ngakho-ke kungenzeka kanjani ukuthi iphrosesa ene-TDP efanayo ebekwe etafuleni njengamamodeli angonyaka odlule ayi-6 isikwazi ukupholisa i-MacBook Pro kangcono kunama-chips angonyaka odlule angenamandla kangako?
Noma ngabe kuyini, i-8-core MacBook Pros entsha iyasebenziseka, ngokungafani nabanduleli bangonyaka odlule, futhi abasebenzisi akudingeki bakhathazeke ngokukhokha okwengeziwe ekucushweni okuphezulu kwe-line. Imisebenzi yomthelela edinga ukusebenza kwesikhashana ilungile kule MacBook, kodwa ngokungafani nemodeli yangonyaka odlule, ingaphatha nemisebenzi yesikhathi eside.
