Pavel Jelic Uma ungenalo ulwazi oluphelele emhlabeni wezobuchwepheshe bolwazi, kodwa ungathanda ukwandisa ama-horizons akho, kungase kube usizo kuwe ukwazi ukuthi yini i-thermal throttling. Ngokuvamile ungahlangabezana naleli gama ikakhulukazi ngama-processor, emhlabeni we-Apple ikakhulukazi esimweni se-13″ MacBook Pro, kanye ne-MacBook Airs entsha. Kodwa-ke, i-thermal throttling nakanjani ayenzeki kuma-laptops e-Apple kuphela, kodwa futhi kumakhompiyutha edeskithophu yakudala noma izincwadi zokubhalela ezivela kwezinye izinhlobo. Ake sihlanganise i-thermal throttling kulesi sihloko.
Kungaba njalo okuthakaselayo
Yini i-thermal throttling?
Ekuqaleni nje, kungaba kuhle ukuhumusha igama elithi thermal throttling olimini lwesi-Czech, okuzosiza ngokuqinisekile abaningi benu ekuzimbeni kangcono. I-Thermal throttling ingahunyushwa ngokukhululekile ngesi-Czech ngokuthi ukusebenza "throttling" ngenxa lokushisa eliphezulu. Njengoba ngishilo esingenisweni, izibonakalisa kuma-chips ahlukene - isibonelo, ku-processor eyinhloko, ku-chip yekhadi lehluzo, noma kwezinye izingxenye ze-hardware. Ivame ukuzibonakalisa uma wenza idivayisi yakho imatasa ngemisebenzi eminingana eyahlukene - ikakhulukazi, ukwenza ividiyo, ukusebenzisa izinhlelo zokusebenza ezimbalwa ngesikhathi esisodwa, noma mhlawumbe ukudlala imidlalo.
Izibonakalisa kanjani?
Ukuze iphrosesa ikwazi ukuphatha zonke lezi zenzo, kufanele "ivuke" kumodi yokulala futhi iqale ukusebenza kanzima. Ngakho-ke iphrosesa izokhuphula imvamisa yayo ibe ngangokunokwenzeka, noma isebenzise okuthiwa yi-Turbo Boost (bona ngezansi). Lapho imvamisa inyuswa futhi lapho ukusebenza ngokuvamile kunyuswa, iphrosesa iqala ukushisa, kalula ukuya emazingeni okushisa ahlasela ikhulu lamadigri Celsius. Amaprosesa akhiwe ukuze asebenze emazingeni okushisa aphezulu, kodwa lokho okweqile kuningi kakhulu. Ngokushesha nje lapho iphrosesa ifinyelela umkhawulo othile wokushisa, ukusebenza kwayo kufanele kuncishiswe ngokunembile ngenxa yokushisa okuphezulu ukuze kugwenywe ukulimala okungapheli ku-hardware - futhi lesi simo sibizwa ngokuthi i-thermal throttling. Ama-coolers ahlukahlukene kanye nezinhlelo zokupholisa zisiza ekwehliseni izinga lokushisa, kodwa kwezinye izimo ukupholisa kuba ngaphansi futhi iphrosesa ayanele, okuyisimo sama-MacBooks amasha, amancane... kodwa akuwona umthetho ukuthi kuhlale kuyiphutha umenzi wekhompyutha (bona futhi ngezansi).
I-thermal throttling kubantu
Ukuze ukwazi ukubona ngeso lengqondo isimo esiphathelene ne-thermal throttling kangcono, singayidlulisela kalula kumuntu osebenzayo. Uma uhamba ngokwe-classical, usebenza ngaphandle kwezinkinga, umzimba awushisi nganoma iyiphi indlela futhi uyasebenza. Kodwa-ke, uma usuqalile (ukunikeza imisebenzi enzima kakhulu), uyagijima futhi ngemva kwesikhashana uqala ukujuluka nokuphelelwa umoya. Uma usesimweni esihle (isistimu yokupholisa), khona-ke ukugijima akuyona inkinga, ngaphandle kwalokho kufanele ume futhi uphefumule (i-thermal throttling).

David Hanak I-Intel, i-Turbo Boost kanye ne-thermal throttling
Sihlangabezana negama elithi thermal throttling kaningi ngamaphrosesa avela ku-Intel. Lawa maphrosesa anomsebenzi obizwa nge-Turbo Boost, osetshenziselwa uhlobo "lwe-overclocking" lweprosesa. Isibonelo, i-13″ MacBook Pro yakamuva inephrosesa ye-quad-core Intel Core i5 eyisisekelo esebenza ngesivinini sewashi esingu-1,4 GHz, ne-Turbo Boost isivinini sewashi singafinyelela ku-3,9 GHz. Ewashi lesisekelo, iprosesa ayinayo inkinga, kodwa ngokushesha nje lapho "i-overclocked" nge-Turbo Boost, ukusebenza kwayo kuzokwanda, kodwa-ke izinga lokushisa layo lizokwanda. Amadivayisi ngokuvamile awakwazi ukupholisa lawa mazinga okushisa, ngakho-ke i-thermal throttling iphinda isebenze. Ngokuvamile, esimweni sama-MacBooks amasha, amancane, iphrosesa ingasebenza kufrikhwensi yewashi le-Turbo Boost amashumi ambalwa amasekhondi. Ngakho-ke ukuphishekela izinombolo ezingcono ephepheni akusizi ngalutho kuleli cala.

Umkhiqizi wekhompiyutha akahlali ebhekene ne-thermal throttling
Nokho, inkinga kuleli cala ingase ingabi ngokuphelele ngasohlangothini lomkhiqizi wekhompyutha. Yize i-Apple izama ukwenza ama-MacBooks abe mancane futhi abe mancane, okuyinto engakusizi ukungena komoya, kodwa isenohlelo lokupholisa oluphethwe kahle. Ngeshwa, inkinga kulezi zimo ivame ukuba ngasohlangothini lwe-Intel, amaphrosesa ayo akamuva ane-TDP yangempela ephakeme nangaphezulu (Thermal Design Power). I-TDP yeprosesa, empeleni, ikhipha umshini wayo oshisayo ophezulu, okumele i-cooler yenqubo ikwazi ukukuhlakaza. Ngokokuhlolwa, i-TDP yangempela yesizukulwane seshumi sakamuva se-Intel processors icishe ibe ngu-10 W, okuyinto eningi ngempela yokupholisa ikhompuyutha encane njenge-130″ MacBook Pro (noma iMacBook Air). Ngakho-ke, i-Intel ikakhulukazi kufanele ibeke isandla sayo emsebenzini futhi izame ukunciphisa i-TDP ephezulu yabaprosesa bayo - esincintisana nabo i-AMD ikhombisa ukuthi akuyona into eyinkimbinkimbi kangako. Vele, i-Apple ingaphinde ithuthukise ukupholisa kwayo, ngezindleko zokwenyuka okuncane kuwo wonke umshini. Kodwa-ke, i-Intel inecala elikhulu kuleli cala.
Isistimu yokupholisa eklanywe kabusha ye-16″ MacBook Pro:
Isixazululo?
Izinkinga zokushisisa ngokweqile kweMacBook zingaxazululwa maduze ngokuguqukela kwe-Apple kumaphrosesa ayo e-ARM, osekunesikhathi eside isebenza kuwo. I-Intel ibonakala iwumthombo ompofu wama-CPU amakhompyutha we-Apple muva nje, ngenxa ye-TDP yabo empofu kanye "nokungakwazi" kwabo ukusungula izinto ezintsha. Inkampani eyimbangi ye-AMD ikwazile ukudlula i-Intel cishe kuyo yonke imingcele futhi kungaqashelwa ukuthi i-Intel ayizange ifinyelele umkhawulo we-silicon. Ngakho-ke asethembe ukuthi ukushisa ngokweqile kwamakhompyutha we-Apple kuzoxazululwa maduze - kungaba ngokuqwashisa kwe-Intel, ukupholisa okungcono, noma ukuguqukela kwe-Apple kuma-ARM processors, okungenzeka angeke abe ne-TDP embi kakhulu.

Isihloko esihle esinokuqonda, ngiyabonga.
Bekuyinjabulo… :)
Ngiyabonga ngesihloko esicacile.
Okuningi nje !!!
Futhi i-Apple ayikwazanga ukushintshela ku-AMD? :)
Ukupholisa okuklanywe kabi akuyona inkinga ye-Intel, kodwa eka-Apple. E-Cupertino, kumele bazi kahle ukuthi laba baprosesa baqhuba kanjani ngokushisa okukhazimulayo.
