Pavel Jelic Ngati simunadziwe bwino zaukadaulo wazidziwitso, koma mukufunabe kukulitsa mahorizoni anu, zitha kukhala zothandiza kuti mudziwe chomwe chiwopsezo chamafuta ndi chiyani. Nthawi zambiri mumatha kukumana ndi mawu awa makamaka ndi mapurosesa, mdziko la Apple makamaka pankhani ya 13 ″ MacBook Pro, komanso MacBook Airs yatsopano. Komabe, kuwotcha kwamafuta sikuchitika kokha mu laputopu ya Apple, komanso m'makompyuta apakompyuta apamwamba kapena zolemba zamitundu ina. Tiyeni tiyike kugunda kwamafuta pamodzi m'nkhaniyi.

Kodi kutentha kwapakati ndi chiyani?
Pachiyambi pomwe, zingakhale bwino kumasulira mawu akuti thermal throttling mu Czech, zomwe zingathandize ambiri a inu kuti mukhale ndi malingaliro abwinoko. Kutentha kotentha kumatha kumasuliridwa momasuka ku Czech ngati ntchito "throttling" chifukwa cha kutentha kwambiri. Monga ndanenera kumayambiriro, zimawonekera mu tchipisi tosiyanasiyana - mwachitsanzo, mu purosesa yayikulu, mu chip makadi ojambula, kapena zigawo zina za Hardware. Nthawi zambiri zimawonekera mukamapangitsa chipangizo chanu kukhala chotanganidwa kwambiri ndi ntchito zingapo zosiyanasiyana - makamaka, mwachitsanzo, kuwonetsa kanema, kugwiritsa ntchito mapulogalamu angapo nthawi imodzi, kapena kusewera masewera.
Kodi zimadziwonetsera bwanji?
Kuti purosesa igwire ntchito zonsezi, iyenera "kudzuka" kuchokera kumayendedwe ogona ndikuyamba kugwira ntchito mwakhama. Purosesayo amawonjezera ma frequency ake mpaka momwe angathere, kapena atumize otchedwa Turbo Boost (onani pansipa). Pamene mafupipafupi akuwonjezeka ndipo pamene ntchito ikuwonjezeka, purosesa imayamba kutentha, mosavuta kutentha komwe kumawombera madigiri zana Celsius. Mapurosesa amamangidwa kuti azigwira ntchito kutentha kwambiri, koma chachulukira ndi chambiri. Pulosesa ikangofika pamlingo wina wa kutentha, ntchito yake iyenera kuchepetsedwa ndendende chifukwa cha kutentha kwakukulu kuti zisawonongeke kwa hardware - ndipo ndendende chodabwitsa ichi chimatchedwa thermal throttling. Zozizira zosiyanasiyana ndi machitidwe ozizira amathandizira kuchepetsa kutentha, koma nthawi zina kuzizira kumakhala kochepa kwambiri ndipo purosesa sikokwanira, zomwe zimakhala ndi MacBooks ang'onoang'ono ... koma si lamulo kuti nthawi zonse ndilo vuto la wopanga makompyuta (onaninso pansipa).
Thermal throttling mwa anthu
Kotero kuti mutha kulingalira momwe zinthu zilili ponena za kutentha kwa kutentha pang'ono, tikhoza kusamutsira kwa munthu pochita. Mukamayenda mwachikale, mumagwira ntchito popanda vuto lililonse, thupi silitenthetsa mwanjira iliyonse ndipo limagwira ntchito. Komabe, mukangoyamba (kugawa ntchito zofunika kwambiri), mumathamanga ndipo pakapita kanthawi mumayamba kutuluka thukuta komanso kupuma movutikira. Ngati muli bwino (dongosolo lozizira), ndiye kuti kuthamanga sikuli vuto, mwinamwake muyenera kuyimitsa ndi kupuma (kutentha kwa kutentha).

David Hanak Intel, Turbo Boost ndi kutentha kwamphamvu
Timakumana ndi mawu akuti thermal throttling pafupipafupi ndi mapurosesa ochokera ku Intel. Mapurosesa awa ali ndi zomwe zimatchedwa Turbo Boost ntchito, yomwe imagwiritsidwa ntchito ngati "overclocking" ya purosesa. Mwachitsanzo, 13 ″ MacBook Pro yaposachedwa ili ndi purosesa yoyambira ya quad-core Intel Core i5 yomwe imagwira ntchito pa liwiro la wotchi ya 1,4 GHz, yokhala ndi Turbo Boost liwiro la wotchi limatha kufikira 3,9 GHz. Pa wotchi yoyambira, purosesa ilibe vuto, koma itangoyamba "overclocked" ndi Turbo Boost, ntchito yake idzawonjezeka, koma ndithudi kutentha kwake kudzawonjezekanso. Zipangizo nthawi zambiri zimalephera kuziziritsa kutentha kumeneku, kotero kuti kutentha kumabweranso. Nthawi zambiri, pankhani ya MacBooks ang'onoang'ono, purosesa imatha kugwira ntchito pa Turbo Boost wotchi pafupipafupi kwa mphindi khumi zokha. Kufunafuna manambala abwino pamapepala kotero kuli kopanda phindu pankhaniyi.
13 ″ MacBook Pro (2020):
Zithunzi
Wopanga makompyuta sakhala ndi udindo wowongolera kutentha
Komabe, vuto ili silingakhale kumbali ya wopanga makompyuta. Ngakhale Apple ikuyesera kupanga MacBooks kukhala yaying'ono komanso yaying'ono, zomwe sizithandiza mpweya wabwino, komabe zimakhala ndi njira yoziziritsira yomwe imayendetsedwa bwino. Tsoka ilo, vuto pamilandu iyi nthawi zambiri limakhala kumbali ya Intel, yomwe mapurosesa ake aposachedwa amakhala ndi TDP yapamwamba komanso yapamwamba kwambiri (Thermal Design Power). TDP ya purosesa ndiyo, kunena kwake, kutulutsa kwake kwakukulu, komwe kuziziritsa kumayenera kutha kutha. Malinga ndi mayeso, TDP yeniyeni ya ma processor amakono a 10 a Intel mafoni ali pafupi ndi 130 W, zomwe ndizovuta kwambiri kuziziritsa kompyuta yaying'ono ngati 13 ″ MacBook Pro (kapena MacBook Air). Choncho, Intel makamaka ayenera kuyika dzanja lake ntchito ndi kuyesa kuchepetsa pazipita TDP mapurosesa ake - mpikisano AMD amasonyeza kuti ndithudi si zovuta. Zachidziwikire, Apple ikhozanso kukonza kuziziritsa kwake, pamtengo wowonjezera pang'ono pamakina onse. Komabe, Intel ali ndi mlandu waukulu pankhaniyi.
Makina oziziritsira opangidwanso a 16 ″ MacBook Pro:
Njira yothetsera?
Mavuto akuwotcha a MacBook atha kuthetsedwa posachedwa ndikusintha kwa Apple kupita ku ma processor ake a ARM, omwe yakhala ikugwira ntchito kwa nthawi yayitali. Intel ikuwoneka ngati gwero losauka la ma CPU a makompyuta a Apple posachedwa, chifukwa cha TDP yawo yosauka komanso "kulephera" kwawo kupanga zatsopano. Kampani yolimbana ndi AMD idakwanitsa kuthana ndi Intel pafupifupi mbali zonse ndipo zitha kuwoneka kuti Intel sanadutse malire a silicon. Chifukwa chake tiyembekezere kuti kutentha kwa makompyuta a Apple kuthetsedwa posachedwa - mwina ndi kuzindikira kwa Intel, kuzizira bwino, kapena kusintha kwa Apple kupita ku ma processor a ARM, omwe mwina sangakhale ndi TDP yowopsa.

Nkhani yabwino kwambiri, zikomo.
Zinali zosangalatsa… :)
Zikomo chifukwa cha nkhani yomveka bwino.
Ziri ngati izo !!!
Ndipo kodi Apple sakanasinthira ku AMD? :)
Kuzizira kopangidwa molakwika sivuto la Intel, koma la Apple. Ku Cupertino, akuyenera kudziwa bwino momwe ma processor awa akuchitira ndi kutentha kotentha.
