David Hanak 15 ″ MacBook Pro yatsopano yokhala ndi purosesa ya 8-core yafika m'manja mwa owunikira ofuna kudziwa, ndipo kuwonjezera pakuyesa magwiridwe antchito, titha kudziwa momwe MacBook imagwirira ntchito. Makamaka m'dera lozizira, panali chinthu chachikulu chosadziwika mumlengalenga, chifukwa MacBook Pros anali ndi vuto loziziritsa ngakhale chip-6-core chip kuchokera ku Intel, chomwe Apple adayenera kuthetsa chaka chatha chinali chochepa kwambiri (ndi kutentha) mapulogalamu.
Izo zikhoza kukhala chidwi inu
Core i9-core i4 mumitundu ya chaka chatha idavutika ndi kuzizira kofooka kwa MacBook Pro, chifukwa chomwe purosesayo sinathe kugwira ntchito pama frequency omwe awonetsedwa. Pafupifupi atangoyamba kunyamula katunduyo, adayenera kutsekedwa, ndipo pamapeto pake ntchito yake inali pamlingo wofanana ndi mitundu ya XNUMX-core. Apple pamapeto pake idathetsa vutoli posintha pulogalamuyo ndikusintha, koma zotsatira zake zikadali zokayikitsa. Kuphatikizira chip champhamvu kwambiri motero kunadzutsa kukayikira kovomerezeka.
Okonza ma seva Mapulogalamu adagwiritsa ntchito benchmark yotchuka ya Cinebench R20 poyesa. Komabe, m'malo mothamangira kumodzi kwa benchmark, adayesa mayeso mosalekeza wina ndi mnzake kuti athe kutengera kuchuluka kwa nthawi yayitali pa purosesa.
Atangoyamba kuyesa koyamba, ma purosesa adakwera kufika pamtengo wotsatsa wa Turbo Boost level, i.e. 5 GHz. Pafupifupi nthawi yomweyo pambuyo pake, masensa a kutentha kwa purosesa amajambulidwa kufika madigiri 100, omwe ndi malire (okwera kwambiri) pamene chip chidzatsekedwa ndi cholinga chochepetsera kutentha kwa opaleshoni - chomwe chimatchedwa kutentha kwa kutentha. Komabe, m'malo motsitsa ma frequency ku wotchi yoyambira ya 2,4 GHz, MacBook idakwanitsa kusunga ma frequency a chip pakati pa 2,9 ndi 3 GHz, zomwe ndi zotsatira zabwino kwambiri.
Pakuyesa kwanthawi yayitali, ma frequency adakhazikika mozungulira 3 GHz yomwe tatchulawa, pomwe kutentha kwa chip kunali pamlingo wa madigiri 94, omwe akadali pamalire a nthawi yayitali yotetezeka (kutentha kwambiri pang'onopang'ono). kuwononga tchipisi, makamaka ikafika pakulemetsa kwa nthawi yayitali).
Mkhalidwe wovuta wakuziziritsa mapurosesa amphamvu kwambiri mu MacBook Pro uli ndi zifukwa zingapo. Apple siili yolakwa kwambiri pa yoyamba, chifukwa mapangidwe a galimotoyo a m'badwo uno anachitika nthawi ina mu 2015, pamene Intel adalengeza za kubwera kwa mibadwo yatsopano ya tchipisi yomwe idzakhala yamphamvu kwambiri komanso nthawi yomweyo yochuluka kuposa ndalama. m'badwo wakale. Komabe, izi sizinachitike ndipo Intel adatembenuza mtengo wa TDP kukhala kalendala yosweka, yomwe pamapeto pake idachotsedwa ndi opanga laputopu, omwe anali ndi kuziziritsa kale komanso kokhazikika.
Komabe, Apple ilinso ndi mlandu chifukwa cha njira yozizirira yochenjera yomwe idapangira MacBooks ake. Malamulo a physics sangathe kupotozedwa, ngakhale Apple idakwanitsa kuziziritsa mapurosesa apamwamba kwambiri m'badwo waposachedwa wa MacBook Pros.
Nthawi yomweyo, palibe amene akudziwa momwe Apple idathandizira. Pankhani ya hardware, sipanakhalepo kusintha kozizira kapena mawonekedwe a chassis. Njira yozizira ikadali yofanana, monganso fan ndi radiator. Ndiye zingatheke bwanji kuti purosesa yokhala ndi tebulo lofanana la TDP monga momwe mitundu 6-core anali nayo chaka chatha, tsopano imatha kuziziritsa MacBook Pro kuposa momwe idalili chaka chatha ndi tchipisi tating'onoting'ono?
Mulimonse momwe zingakhalire, 8-core MacBook Pros yatsopano ndi yogwiritsidwa ntchito, mosiyana ndi omwe adatsogolera chaka chatha, ndipo ogwiritsa ntchito sayenera kuda nkhawa kuti azilipira zoonjezera pakusintha kwapamwamba. Ntchito zomwe zimafuna kugwira ntchito kwakanthawi kochepa ndizabwino pa MacBook iyi, koma mosiyana ndi mtundu wachaka chatha, imathanso kugwira ntchito zazitali.
