Okufanele Ukwazi Ngaphambi Kokuthenga iMac
I-Apple iMac iyinkimbinkimbi yekhompuyutha yedeskithophu ehlanganisa amandla we-latest Kaby Lake Intel i5 noma i-processor core engu-21.5-inch noma 27-inch display, kanye nokusiza okukhulu kwegama lika-Apple elifanelwe kahle ngesitayela. Umphumela uyimvelo yedeskithophu enhle, e-in-eyodwa Mac ebekade ibeka amathenda embonini kusukela ekuqaleni kwayo ngo-1998.
Njalo ikhompyutha yonke-in-eyodwa idinga okungenani i-tradeoffs embalwa. Ngaphambi kokuba unqume ukuthi i-iMac izobukeka idakile etafuleni lakho, ake sihlolisise amanye ama-tradeoffs bese sibona ukuthi i-iMac iyilungele yini izidingo zakho.
Ukwandisa noma ukungabi nalutho
Umklamo we-iMac unciphisa izinhlobo zokunwetshwa abasebenzisi ekupheleni, kodwa lokho akuyona into embi. Lesi sinqumo sokuvumela sivumela i-Apple ukuthi ihlele umshini omuhle, ohlangene onabo bonke abantu abaningi abazokudingwa.
I-iMac yenzelwe abantu abasebenzisa isikhathi sabo esiningi besebenza ngekhompyutha yekhompuyutha, futhi isikhathi esincane noma esingenaso isikhathi sokwenza i-hardware. Lokhu kuhlukaniswa okubalulekile, ikakhulukazi uma ujabulela ukuhambelana ne-hardware ngaphezu kwakho. Kodwa uma ufuna nje ukwenza umsebenzi ufeze (futhi ujabule kancane), i-iMac ingaletha.
I-RAM enwetshiwe
I-iMac kungenzeka ingabi nezimo eziphathekayo uma kuziwa kwi-hardware engaguquguqukayo yomsebenzisi, kodwa kuye ngokuthi imodeli, i-iMac ayikwazi ukuba nomsebenzisi we-RAM ongafinyeleleka, ama-RAM slots amabili afinyelelekayo yomsebenzisi, noma ama-RAM angenawo wonke ama-RAM.
Izinguqulo zakamuva zakwaMac 21.5-intshi ziye zayeka ukusetshenziselwa ama-RAM okufinyeleleka ekusebenziseni ama-slots angaphakathi angadinga ukuxoshwa okuphelele kwe-iMac ukushintsha i-RAM, umsebenzi olukhuni kakhulu, noma i-RAM esetshenziselwa ngokuqondile kwi-motherboard yeMac. Uma ucabangela iMac iMac 21.5-intshi, ungase ufune ukuyala ikhompuyutha nge-RAM engaphezu kokucushwa okujwayelekile ngoba ngeke ukwazi ukuthuthukisa i-RAM ngosuku oluthile, okungenani hhayi ezimweni eziningi.
I-iMac yama-27 intshi, kungakhathaliseki ukuthi imodeli, isinezinhlelo ezine ze-RAM ezifinyelelekayo zomsebenzisi, okukuvumela ukuba wandise i-RAM ngokwakho. I-Apple inikeza ngisho nemiyalelo enemininingwane yokuthi ungayithola kanjani i-RAM slots bese ufaka amamojula amasha we-RAM.
Futhi cha, awunamathengi ukuthenga i-RAM kusuka ku-Apple; ungathenga i-RAM kubathengisi abaningi abavela eceleni. Vele uqinisekise ukuthi i-RAM oyithengayo ihlangabezana nezimpawu ze-RAM ze-iMac.
Uma ucabangela ukuthenga i-iMac entsha yamasentimitha angu-27, cabanga ukuthenga i-iMac ehleliwe nge-RAM encane, bese uthuthukisa i-RAM ngokwakho. Ungagcina i-nice chunk yashintsha ngale ndlela, engakushiya imali ethile yokuthenga izinhlelo zokusebenza noma izingcingo ongazidingayo.
I-iMac Pro engu-27 intshi iyimodeli entsha yomkhiqizo okwamanje kuboniswa kuphela ukucindezela nabathuthukisi. I-iMac Pro inezincazelo ezihlaba umxhwele kuhlanganise kuze kufike kuma-processors angu-18. Yini engaziwa ukuthi ngabe i-pro pro ye-iMac izoba ne-RAM yokuvuselela yomsebenzisi. Kuze kube manje ukuhanjiswa kwe-iMac Pro kuboniswa akunawo ama-pane wokufinyelela ama-RAM. Kodwa lokhu kuyisisindo, futhi i-iMac Pro ayilungiselelwe ukuba itholakale kuze kube sekupheleni kuka-2017. Sizokwazi ukuthi uma i-RAM ingafinyelelwa ngumsebenzisi wokugcina.
Thuthukisa i-RAM yakho ye-Mac Wena ngokwakho: Okudingeka Ukwazi
Ukubonisa: Usayizi nohlobo
I-iMac itholakala ngobukhulu bombukiso obubili, futhi ibonisa izinqumo ezimbili ezahlukene. Ngaphambi kokubuka ukubukeka kwe-Retina noma okujwayelekile, ake siqale ngombuzo wesayizi.
Ngokuvamile kuthiwa okukhulu kuncono. Uma kuziwa ekuboniseni iMac, okungenani, lokhu kuyiqiniso ngempela. Itholakala kuzinguqulo ezingu- 21.5-intshi no- 27-intshi , kokubili iMac izibonisi zenza kahle, zisebenzisa amapaneli e-IPS LCD ne-LED ukukhanyisa. Le nhlanganisela inikeza i-angle ebanzi yokubukwa, ububanzi obukhulu obuhlukile, nobuqotho obuhle bombala.
Okuwukuphela kwendlela engase ibe yinkinga ekubonisweni kwe-iMac ukuthi kuhlinzekwa kuphela ngokucushwa okuluhlaza; akukho ndlela yokubonisa i-matte etholakalayo. Ukuboniswa okuluhlaza kuveza abamnyama abengeziwe futhi imibala enamandla kakhulu, kodwa ngezindleko zokugaya.
Ngokujabulisayo, ama-iMacs amasha, ikakhulukazi labo abasebenzisa ukubukwa kwe-Retina, bahlonyelwe ukugqoka okulwa ne-glare okusiza ngempela ukugcina ukukhanya.
Ukubonisa: I-Retina noma i-Standard?
I-Apple okwamanje inikeza i-iMac ngezinhlobo ezimbili zokubonisa ngosayizi ngamunye. I-iMac engu-21.5-intshi ihambisana nombukiso ojwayelekile we-21.5-intshi usebenzisa isinqumo se-1920 ngo-1080, noma ukuboniswa kwe-Retina 4K ka-21.5-intshi ngesinqumo se-4096 ngo-2304.
I-iMac engu-27 intshi itholakale kuphela ngokubukwa kwe-Retina 5K engu-27 intshi usebenzisa isinqumo esingu-5120 ngo-2880. Izinguqulo zakuqala ze-iMac yama-27 intshi nazo zazibonisa ukulinganisa okuvamile ku-2560 ngo-1440 isinqumo, kodwa zonke izinhlobo zamuva zisebenzisa ukubonisa okuphezulu kwe-Retina 5K ukubonisa.
I-Apple ichaza ukubukwa kwe-Retina njengokuba ne-pixel ephakeme ngokwanele yokuthi umuntu akakwazi ukubona amaphikseli athile ebangeni elibukwayo elivamile. Ngakho, yimuphi ibanga elibukwayo elivamile? Ngesikhathi i-Apple ivula ukuboniswa kokuqala kwe-Retina, uSteve Jobs uthe ibanga elibukwayo elivamile laliyi-12-intshi. Yiqiniso, wayebhekisela ku-iPhone 4; Angikwazi ukucabanga ukuthi uzama ukusebenza emkhatsini wamasentimitha angu-12 kusuka ku-iMac yami. Isikhathi sami sokusebenza kusuka eMac yami engu-27-intshi iMac siseduze nemigqa yamasentimitha angu-22 noma ngaphezulu. Ngaleso sikhathi, angikwazi ukubona amaphikseli athile, okwenza kube ngenye yezinto ezibukeka kahle kakhulu engake ngibone.
Ngaphandle kwamandla we-pixel, i-Apple iye yazama umzamo omkhulu ukuqinisekisa ukuthi ukubukeka kwe-Retina kunombala omkhulu webala, ukuhlangana noma kudlula ububanzi be-gaming ye-DCI-P3. Uma ukhathazeka ngesikhala sombala, khona-ke ukubukeka kwe-iMac's Retina kuyindlela enhle kakhulu. Kungase kungahambisani nabaqaphi bombala ophezulu, kodwa khumbula, uma uthenga i-iMac, uthola ikhompyutha ye-Mac kanye nokubonisa okungaphansi kwezindleko zabahloli abangu-5K ngokwabo.
Isitoreji: Okukhulu, Ngokushesha, Noma Kokubili?
Ukuze i-iMac, impendulo ixhomeke kuhlobo lokugcina. Izinguqulo ezisemqoka zama-iMacs angu-21,5-intshi zihlomele nge-hard drive ye-5400 RPM 1 TB ngenkathi i-iMac engu-27 intshi isebenzisa i-1 TB Fusion drive njengesisekelo sayo. Ngokushesha uzoba iMac Pro iqala nge-SSD ye-1
Kusuka lapho, ungadlulela ku-drive ye-Fusion , ehlanganisa i-PCIe yokugcina isitoreji se-flash nge-1, 2, noma i-3 TB 7200 RPM drive hard. I-drive ye-Fusion ikunika okungcono kunazo zonke zomhlaba ngoba iyakwazi ukunikeza isivinini esingcono kune-hard drive, nendawo enkulu yokugcina isitoreji kunama-SSD amaningi.
Uma imoto ye-Fusion ingahlangabezani nezidingo zakho, futhi isivinini yilokho okudingayo, ngakho wonke ama-iMac onobuhle angalungiswa nge-PCIe-based based storage systems, kusuka ku-256 GB kuya ku-2 TB.
Khumbula, ngeke ukwazi ukushintsha kalula i-hard drive yangaphakathi kamuva, ngakho-ke khetha ukucushwa ongakukhokhela kahle. Uma izindleko kuyinkinga ngempela, ungazi ukuthi kufanele uphonse isabelomali phambili. Ungakwazi njalo ukungeza i- hard drive yangaphandle kamuva, nakuba lokho kunqoba kakhulu inhloso yikhompyutha yonke-in-eyodwa.
Amamodeli we-iMac anikezela ukukhuliswa kwangaphandle usebenzisa amachweba we- Thunderbolt 3 ne- USB 3 .
Izinketho ze-Graphics Processor
Ihluzo ze-iMac zifikile kude kusukela ezinhlobonhlobo zangaphambili. I-Apple ijwayele ukuguquka phakathi kwehluzo le-AMD Radeon, ihluzo ezisuselwe ku-NVIDIA, ne-GPU edidiyelwe ye-Intel.
Amamodeli wamanje we Retina iMacs angu-27-intshi asebenzisa i-AMD Radeon Pro 570, 575, no-580, kuyilapho i-iMac engu-21.5-intshi isebenzisa i-Intel Iris Graphics 640 noma i- Radoen Pro 555, 560.
Ngenkathi izinketho ze-Intel zegrafu zingabantu abenza kahle, i-AMD Radeon ihluzo ezihluzekile yiyona ndlela engcono kakhulu kulabo abasebenza ngokusebenza ngevidiyo nezithombe. Banikeza nokusebenza okuhle kakhulu uma kudingeke uthathe ikhefu futhi udlale imidlalo embalwa.
Izwi lokuqapha: Ngisho noma ngishilo ukuthi amanye amamodeli e-iMac asebenzisa ihluzo eziphathekayo, lokho akusho ukuthi ungabuyekeza noma ubuyekeze ihluzo. Ihluzo, ngenkathi isebenzisa izingxenye eziqondile ezizinikezelwe ihluzo, zisengxenyeni ye-iMac's motherboard design, futhi ayikho amakhadi ehluzo e-shelf angathengwa kubantu besithathu. Awukwazi ukuthuthukisa amahluzo ngosuku oluthile.
Ngakho, Yiziphi Izinzuzo ze-iMac?
I-iMac inikeza izinzuzo eziningi phezu kwezidakamizwa zendabuko. Ngaphandle kwesimo esincane esicacile, i-iMac nayo inekhwalithi enhle kakhulu, isibonisi esikhulu, esibucayi esingahle sithengise noma yikuphi kusuka ku-$ 300 kuya ku-$ 2,500 uma kuthengwa njengesiboniso se-LCD esilinganayo.
I-iMac iza izikhwebu nezinye ze-hardware ezikhangayo neziwusizo kanye nesofthiwe ehambisana ne-Mac Pro. Imikhumbi ye-iMac enekhamera ye-iSight eyakhelwe ngaphakathi ne-microphone, izitifiketi ezakhelwe ngaphakathi, ikhibhodi ye-Bluetooth, ne- Magic Mouse 2 .
Ingabe i-iMac Right For You?
I-iMac yikhompyutha enkulu, engingayiboni njengento engalungile kubantu abaningi. Isibonisi esakhelwe ngaphakathi siyamangalisa. Futhi ake sibhekane nakho: I-form ye-iMac ifomu ngokungangabazeki enye ye-sleekest futhi engcono kakhulu etholakalayo kwikhompyutha yedeskithophu.
Naphezu kokubhenela okusobala, i-iMac okungenani ekusetshenzisweni kwayo kwe-base kungenzeka kube yisinqumo esimpofu sezithombe eziphambili nezithombe zevidiyo, ezidinga ihluzo ezinamandla kunokuba zitholakale ezingeni lokungena iMac. Ama-Graphics namavidiyo wezinhlelo zithuthukiswa kangcono nokukhuliswa okungaphezulu kwe-RAM nokunye okukhethwa kukho kokugcina isitoreji, izici ezenza i-iMac ne- Mac Pro engu-27 intshi ibe yindlela engcono yezidingo zabo.
Ngakolunye uhlangothi, i-iMac, ikakhulukazi labo abanokubukwa kwe-Retina, ingaba yisinqumo esifanele kunoma iyiphi i-pro-photographer noma i-photographer ye-amateur, umhleli wevidiyo, umhleli we-audio, noma i-junkie nje ecacile efuna ukusebenza okuvelele ngaphandle kokuphula ibhange.
