Ukuphucula i-RAM yakho ye-RAM: Oko Okufuneka Ukwazi
Ukubonisa: Uhlobo kunye nohlobo
I-iMac ifumaneka kumabonakaliso amabini, kwaye ibonakalisa kwizigqibo ezimbini ezahlukeneyo. Ngaphambi kokuba sijonge kwi-Retina okanye i-Standard display, makhe siqale ngombuzo wobukhulu.
Ngokusoloko kuthiwa lukhulu ngakumbi. Xa kuziwa kwimiboniso ye-iMac, ubuncinane, oku kuyinyaniso. Efumaneka kwiinguqu ezingu-21,5-intshi kunye nee -intshi ezingama-27 , zombini iMac zibonisa kakuhle, isebenzisa ipaneli ye-IPS LCD kunye nokukhanyisa kwe-LED. Olu dibana lunikeza i-angle ebonakalayo ebanzi, ububanzi obukhulu, kunye nobuhle obuhle bombala.
Okukuphela kwendlela engenakwenzeka kwimbonakalo ye-iMac kukuba yenziwa kuphela kwisilungiso esilumkileyo; akukho ndlela yokubonisa i-matte ifumaneka. Isiboniso esicwebezelayo sivelisa abamnyama abamnyama kunye nemibala emininzi, kodwa kwiindleko ezibonakalayo ze-glare.
Ngombulelo, i-iMacs entsha, ingakumbi abo basebenzise ukubukeka kwe-retina, beza kuxhotyiswa ngeengubo ezichasayo eziza kunceda zihlale zikhanya.
Ukubonisa: I-Retina okanye i-Standard?
I-Apple njengamanje inikeza i-iMac kunye neentlobo ezimbini zokubonisa ubungakanani obufanayo. I-iMac ye-21.5 intshi iza kunye nomboniso oqhelekileyo we-21.5-intshi usebenzisa u-1920 ngo-1080 isisombululo, okanye ukuboniswa kwe-Retina 4K ye-21,5 intshi nge-4096 ngo-2304.
IMac i-27 intshi i-iMac ifumaneka kuphela ngokuboniswa kwe-Retina 5K ye-27 intshi usebenzisa i-resolution ye-5120 nge-2880. Iinguqu zokuqala ze-iMac 27-intshi nazo zineemboniso eziqhelekileyo ezikhoyo kwisisombululo esingu-2560 ngo-1440, kodwa zonke iimodeli zakutshanje zisebenzisa isisombululo esiphezulu se-Retina 5K.
I-Apple ichaza ukubonakalisa i-retina njengokuba neqondo eliphezulu ngokwaneleyo lepikseli ukuba umntu akakwazi ukubona iipekseli ngamanqaku aqhelekileyo. Ngoko, yintoni umgama oqhelekileyo wokubukela? Xa i-Apple ivule umboniso wokuqala we-retina, uSteve Jobs uthe umgama oqhelekileyo wokubukela wawungama-intshi ezili-12. Ewe, wayebhekisela kwi-iPhone 4; Andiyi kucinga ukuba ndizame ukusebenza ku-12-intshi ukusuka kum iMac. Umgama wam oqhelekileyo osebenzayo ukusuka kwi-iMac yam-intshi engama-27 ihamba ngaphezu kwee-intshi ezingama-22 okanye ngaphezulu. Kuloo mgama, andinakubona iipekseli ngamanye, kubangele enye yeemboniso ezikhangele phambili endingazibona.
Ngaphandle kwe-pixel ukuxininisa, i-Apple iye yazama umgudu wokuqinisekisa ukuba i-Retina ibonisa imibala ebanzi, idibano okanye idlula i-DCI-P3. Ukuba ukhathazeka ngendawo yombala, ukubonakaliswa kwe-iMac ye-Retina kukukhetha okulungileyo. Akunakufanisa nabagadi beembala eziphezulu, kodwa khumbula, xa uthenga i-iMac, ufumana ikhompyutha ye-Mac kunye nomboniso ongaphantsi kweendleko zabakhokeli abangama-5K ngokwabo.
Ukugcinwa: Okukhulu, Ngokukhawuleza, okanye zombini?
Kwi iMac, impendulo ixhomekeke kuhlobo lokugcina. Iinguqulelo ezisisiseko zeMacs ezingama-21,5-intshi ziza zixhotyiswe nge-hard drive ye-5400 RPM 1 TB ngelixa iMac i-27-intshi i-iMac isebenzisa i-1 TB ye-Fusion drive njengesiseko sayo. Ngokukhawuleza ukufumana iMac Pro iqala nge-SSD ye-TB
Ukusuka apho, unokunyuka ukuya kwi-Fusion drive , edibanisa i-PCIe yokugcina i-flash drive kunye ne-1, 2, okanye i-3 TB 7200 RPM drive drive. I-drive ye-Fusion ikunika okulungileyo kwezo zombini ihlabathi ngenxa yokuba inako ukunikela ngesantya esiphezulu kunokuba i-hard drive, kunye nendawo enkulu yokugcina indawo kuninzi ii-SSD.
Ukuba i-Fusion drives ayihlangabezani neemfuno zakho, kwaye isantya kukufunekayo, ke zonke iimodeli zeMac zingaqwalaselwa ngeenkqubo ze-PC-based based storage, ukusuka kwi-256 GB ukuya kwi-2 TB.
Khumbula, awuyi kukwazi ukutshintsha i-drive yangaphakathi yecala ngokukhawuleza kamva, ngoko ukhethe uqwalaselo onokukufumana ngokufanelekileyo. Ukuba iindleko ziyimpikiswano, musa ukuziva ukuba kufuneka uqhube uhlahlo lwabiwo-mali phambi. Unako ukuhlala udibanisa idrayivu yangaphandle kamva, nangona loo nto inokutshatyalalisa injongo yikhompyutha nganye.
