David Hanak Ngenkathi i-Apple yethula i-iMac Pro ngonyaka odlule, ngaphandle kwentengo, abantu abaningi bazibuza ukuthi i-Apple izoyixazulula kanjani inkinga yokupholisa. Konke kufomu elilodwa akusona isixazululo esikahle kakhulu sezingxenye ezifuna ukupholisa ezizoba ngaphansi komthwalo osindayo isikhathi eside. Imikhawulo yokupholisa ye-iMacs yakudala iyisibonelo esanele. Kodwa-ke, i-Apple ikuphikile ukuthi ukupholisa kwe-iMac Pros entsha kuklanywe kabusha ngokuphelele. Manje ihlanganisa amasekhethi amabili okupholisa azimele (amabhulokhi e-CPU ne-GPU). Amafeni kanye nerediyetha nakho kusha. Bahlole isekethe yokupholisa ebuyekeziwe kuseva ye-Appleinsider futhi bathola ukuthi ayinazo izinkinga.
Kungaba njalo okuthakaselayo
Patrik Siwek Bafingqa indatshana yabo enemininingwane kuvidiyo, ongayibuka ngezansi kwalesi sigaba. Ukuhlola, basebenzise ukucushwa "okuyisisekelo" kwe-iMac Pro entsha, ene-8-core Xeon (3,2GHz, 4,2GHz Boost), i-AMD Vega 56 GPU, 32GB DDR4 RAM kanye ne-1TB NVMe SSD. Uma ingenzi lutho, i-iMac Pro entsha ithule ngokuphelele. Ngeke wazi ngakho ngesikhathi somsebenzi ojwayelekile, okungafuneki nhlobo ezingxenyeni ezingaphakathi - okungukuthi ukuphequlula iwebhu, amanye ama-imeyili, njll.
Ngokumangazayo, lesi simo asishintshi ngisho nalapho ividiyo ye-4K ihunyushwa ku-Final Cut Pro X kumodeli ehloliwe, i-iMac Pro yayithule kakhulu, futhi nalapho abalandeli begijima, kwakungekho msindo ovela ngaphakathi. yomshini. Uma kuqhathaniswa ne-iMac evamile ye-5K, lokhu kuthiwa umehluko omkhulu. Kodwa-ke, lokhu "kusebenza ngokuthula" nakho kunemibi yawo. Njengoba kubonakala, lapho uklama izilungiselelo zokupholisa kanye namajika okupholisa abalandeli, i-Apple ikhetha umsindo ophansi ngezindleko zokupholisa ukusebenza.
Esimeni sebhentshimakhi ye-Cinebench R15 CPU yakudala (amaphuzu azuzwe angu-1682), iphrosesa ifinyelele imvamisa engu-3,9GHz. Kodwa-ke, phakathi nokuhlolwa ngakunye okwalandela, kwakukhona ukufakwa ngaphansi kwesikhashana ku-3,6GHz, ngenxa yokwehla kwezinga lokushisa le-chip. Iphrosesa ifinyelele umkhawulo wamadigri angu-94 ngokushesha uma ingaphansi komthwalo, ngemva kokufinyelela lapho kwenzeka khona i-throttling yakudala. Lokhu kwehla kwemvamisa kuthathe cishe imizuzwana emibili, ngemuva kwalokho iphrosesa yavuka futhi yaba ngu-3,9. Lapho i-Cinebench iphindaphindwa, kulapho iphrosesa ivama ukuvalwa ngaphansi kwewashi. Ngakho u-Apple usethe isivinini esikhulu sabalandeli ngenxa yomsindo wokupholisa, futhi isitimela asidluli lokho. Okwamanje, akwenzeki ukusetha amajika okusebenza amafeni okupholisa ngendlela othanda ngayo.
Igalari yezithombe
I-CPU throttling iphinde yavela ngenkathi uhlela ividiyo. Kulokhu, kuthathe cishe imizuzu emithathu ukuthi i-CPU ifinyelele ku-93-94 degrees. Ngaleso sikhathi, ukuncishiswa kwemvamisa okuphindaphindiwe kusuka ku-3,9 kuye ku-3,6 GHz kwaqala. Lokhu kuziphatha kwaphindwa kuso sonke isivivinyo (kulokhu ngesikhathi sokunikezwa kwevidiyo engu-4K), ethathe cishe imizuzu eyi-7 futhi izinga lokushisa lokucubungula laliphakathi kuka-90 no-94 degrees.
Kungaba njalo okuthakaselayo
Isistimu yokupholisa iba phezulu uma i-GPU idinga ukupholiswa ngaphezu kwe-CPU. Esimeni somthwalo kukho kokubili iphrosesa nekhadi lezithombe, umsindo wokupholisa usezingeni elifanayo njengasesimeni se-iMac yakudala engu-5K. Uma isistimu yokupholisa kufanele ipholise nekhadi lezithombe, iphrosesa izofinyelela izinga lokushisa elilinganiselwe (ama-94 degrees) ngokushesha okukhulu. Ngaphambili lokhu kuzoholela ekucindezelekeni nasekunciphiseni ukusebenza. Esimeni somthwalo ohlanganisiwe, iphrosesa iqala ukuya ngaphansi kwewashi iye ku-3,3GHz futhi ibuyele emuva ku-3,6GHz. Imvamisa ye-3,9GHz ayifinyeleleki ngomthwalo ohlanganisiwe, okungenani ngokupholisa okuzenzakalelayo. Ikhadi lehluzo lifinyelele amadigri angu-74 ekuhlolweni, futhi izivivinyo zibonise ukuthi kukhona ukufakwa ngaphansi kwe-underclocking nokulahlekelwa kokusebenza ngisho nalapha ekulayisheni okuphezulu kwesistimu. Lokhu cishe ku-10%.

Ukuhlolwa kuka-Appleinsider kuveze izinto ezimbalwa. Okokuqala, kusobala ukuthi i-Apple ikhetha ukusebenza buthule kwamadivayisi ayo, noma ngabe lokhu kusho ukuthi izingxenye zisebenza emazingeni okushisa aphezulu futhi zingaphansi kwewashi. Ububi obukhulu ukungenzeki kokwenza ukupholisa ngendlela oyifisayo nokudala amajika angokwezifiso namaphrofayili okupholisa. Ngokushesha lapho lokhu kungenzeka, cishe kuzobonakala ekusebenzeni ngokusebenza. Kufanele futhi kubhekwe ukuthi amanye amabhentshimakhi kulokhu kuhlolwa kwengcindezi awameleli umthwalo wangempela iMac Pro ezobhekana nawo. Isibonelo, i-Cinebench noma inhlanganisela yokuhlola ye-CPU+GPU isetshenziselwa ukuhlola kuphela. Ngakolunye uhlangothi, ngingalindela ukuthi ababhali nabo bagxile ekuhlolweni kokucindezeleka kwakudala ekuhlolweni okunjalo. Ngabe imvamisa yephrosesa ingabukeka kanjani ngemuva kwamahora amabili okulayisha? Noma kunjalo, manje ungathola umbono ocacile wokuthi i-iMac Pro entsha isebenza kanjani ngokusebenza kwayo kokupholisa.

Okulungile ngokwegrama "ukupholisa amaphrofayili" hhayi "ukupholisa".
“Iloli lokufafaza lifafaza umgwaqo. Imali yokulondoloza i-akhawunti yokulondoloza. Amakhethini amnyama avala iwindi. Indawo yokupholisa imishini yesiqandisi. …”
Ukuthi ungumCzech? :)
Cha cha. Umdwebi wezandla. :D
Kulungisiwe, ngiyabonga ngamakhanda phezulu kanye nencazelo :)
Uma othile bengenandaba nomsindo, kwanele ukuthenga abalandeli bangaphandle ngamarandi ambalwa futhi uwasebenzise ukupholisa ikhompuyutha. Yebo, ayikhululekile kangako, kepha iyisixazululo esisebenzayo. Ngokwami, ngeshwa, kwesinye isikhathi kufanele ngiyisebenzise. Ngicabanga ukuthi ngifuna okuningi ngemuva kwalowo mshini! ?♂️
Ngifisa sengathi bangathatha isibonelo ezincwadini ze-HP eziqala abalandeli uma becabanga ngomsebenzi.
Izinga lokushisa lekamelo lalingama-degree angu-21. Angikucabange emazingeni okushisa ehlobo. Kodwa kungenzeka ukuthi yenzelwe izindawo ezinomoya opholile. Futhi kwakuyimodeli eyisisekelo nje ...
Ngicabanga ukuthi ikhompuyutha efana ne-iMac Pro ngeke ize ithengwe kwenye indawo ngaphandle kwendawo ene-air-conditioning... :-)
Lokhu akuyona into entsha, i-Apple isinendlela enjalo isikhathi eside, ine-hardware eyenzelwe yona, ikakhulukazi ama-laptops.
Wake wacabanga ukuthi kuyamangaza ukuthi iMacbooks Pro 15 inemithombo ebuthakathaka engama-40W kunabaqhudelana nabo abangaphakathi abafanayo? Ukweqa iphrosesa ngezinga lewashi eliphakeme kuyinto yesikhathi esisodwa kuphela, awuyizwa isikhathi eside, umthombo ubungeke uqinise ihluzo ekusebenzeni okuphezulu kanye nephrosesa eyeqile ngesikhathi esisodwa, ngaphezu kwalokho, isimo esinjalo. akuyona ngisho evamile.
Ngakolunye uhlangothi, ungasebenzisa uhlelo olulula ukusetha amaphrofayili akho okupholisa, ngizenzela mina ngesikhathi semisebenzi enzima ukusindisa izingxenye, ngoba izinguquko zabalandeli ziqala ngempela ukusheshisa lapho amanani omkhawulo efinyelelwa futhi uma ungakwenzi lokho. 'ingaphezu kuka-90C, umlandeli akazami ngisho nokuphola.
