I-New Skylake Processors neMifanekiso Ye-Nimble
I-Apple ivuselele lonke i-iMac lineup ka-2015, kufaka phakathi i -iMac yokuqala engu- 21.5-intshi ne-Retina 4K ukubonisa . I-iMac lineup engu-27 intshi, nokho, ithola okuhle kakhulu kokubuyekezwa. Kukho ama-non-Retina iMacs avela ku-27-inch lineup. Uma uya omkhulu, uya ku-Retina; okungenani, okubonakala sengathi i-Apple ithatha lolu daba, futhi ngivame ukuvumelana.
Kusukela ngo-2014 iMac yeMac in 27 ne-Retina 5K Display yakhululwa, sazi ukuthi, njenge-MacBook Pro ukuhlela, okwakungamamodeli okungewona ama-Retina okwesikhashana (kumamodeli angu-13 intshi), esikhathini eside, U-Retina wayengumqondisi we-Apple ozohamba kuwo wonke umkhiqizo womklamo.
Ngakho-ke, ngaphezu kwayo yonke i-Retina yokuhlela, i-iMac engu-27 intshi ithole izibuyekezo eziphawulekayo ezizojabulisa noma ubani ofuna ukufaka ukusebenza okuningi.
Ukubukwa kwe-retina engu-27 intshi ne-P3 Color Space
Ake siqale ngesiboniso. Ukubukwa kwe-retina engu-27 intshi kungena ku-5K, ngesinqumo se-pixel sika-5120 x 2880. Isibonisi sisasebenzisa iphaneli ye-IPS, kodwa entsha kumodeli ka-2015 iyinhlangano enkulu ye-DCI-P3 yombala wombala. Isikhala sombala se-P3 sikhulu, okungukuthi, sihlanganisa isikhala sombala okhudlwana, singavumeli nje imibala eyengeziwe ukuthi iboniswe, kodwa imibala enamandla kakhulu. Ukucaciswa kombala we-P3 kuyona efanayo okusetshenziselwa imidlalo yeshashalazi yedijithali, kanye nobuchwepheshe bokubuka obusetshenziselwa izithombe zansuku zonke zokuhamba.
Ukwamukelwa kwe-Apple isikhala sombala we-P3 we-iMac entsha yama-27 intshi kubaluleke kakhulu kulabo abasebenza embonini yesithombe sokunyakaza, kanye nanoma ubani osebenza ekukhiqizeni ividiyo. Ngasekupheleni kuka-2014, kwakunezingqapheli ezimbalwa eziqinisekisiwe ze-P3 ezitholakale kubachwepheshe, futhi ngezindleko ezinkulu, ngaphezu kwe-iMac ekhohlisiwe ngokugcwele.
Ngakho-ke, ungabona ukuthi i-iMac entsha ene-P3 ukubukwa kwe-P3 izoba ekhangayo kakhulu.
Abacubungula
Ku-iMac, i-iMac lineup engu-27 intshi, i-Apple yeqa izinqubo zokuqala zesizukulwane sesihlanu se-Broadwell , futhi yahamba ngqo kumamodeli amaningi ase-Skylake . I-iMacs yama-27-intshi ka-2015 inamaprosesa angu-3.2 no-3.3 we-Quad-Core i5, ngokuthuthukiswa okutholakala ku-4.0 GHz Quad-Core i7.
Amamodeli ase-i7 anamakhono okuqhuba izintambo eziyi-8 ezihambisanayo, ngokuyisisekelo ukulinganisa ukusebenza kwe-CPU eyisi-8.
I-processor entsha ye-Skylake ayihlinzeki ngokubaluleka okuphawulekayo ekusebenzeni kwama-model ase-Broadwell, kodwa njengoba i-Apple yeqa phezu kwe-Broadwell, abaproseshi be-Skylake kufanele bakhiphe ukuxhuma okuhle ekusebenzeni nge-2014 iMacs esebenzisa i-processor ye-Haswell.
Inzuzo eyengeziwe yama-processor ase-Skylake ukuthi angcono kakhulu amandla, asebenza ngokupholile ngenkathi ehlinzeka ngokuthuthukiswa kokusebenza. Uma unesibonakaliso esikhulu esingu-27-intshi Retina, ukugcina ukungena kwe-Mac yakho epholile kubaluleke kakhulu.
Ama-Graphics
I-iMacs yama-27-intshi ka-2015 isebenzisa i-AMD Radeon R9 GPUs ekulungiselelweni okuthathu: i-R9 M380 ne-2 GB yememori ye-GDDR5; i-R9 M390, futhi ne-2 GB yememori ye-GDDR5; kanye ne-R9 M395 nge-2 GB yememori ye-GDDR5. Kukhona futhi inketho ye-R9 M395X nge-4 GB yememori ye-GDDR5.
Noma iyiphi ye-AMD GPU izokwazi ukuhambisa kalula ukubukwa kwe-5K futhi isanikeza ukuxhaphaza okunengi kokusebenza kwabasebenzisi abaningi. Uma ngokuyinhloko ucabanga ukuthi usebenzisa i-iMac yokunikeza isithombe nesithombe, i-R9 M395X nenkumbulo enkulu ingase ibe nesithakazelo. Kodwa iningi lethu, kuhlanganise nalabo abangase bazibuze ukusebenza komdlalo, kufanele bathole u-R9 M390 ngaphezulu kunokwanele.
Isitoreji
I-iMac emikhulu engu-27 intshi inezinzuzo ezithile ngenxa yobukhulu bayo, okwenza ukupholisa ingaphakathi kube lula kunamamodeli angu-21,5-intshi iMac. Enye yalezi zinzuzo ukuthi ngisho nesitoreji esisekelwe phansi sisebenzisa i-1 TB 7200 RPM drive. Isilinganiso sokujikeleza esheshayo senza ngisho ne-TB ejwayelekile ye-TB esebenzayo esetshenziselwa imodeli yesisekelo esetshenziselwa abasebenzisi abaningi.
Uma uphakamisa amamodeli wezinyanga eziphakathi noma phezulu, uzothola i-TB ye-TB Fusion noma i-TB ye-TB ye-2 njengezinga elincane. Ungathuthukisa isitoreji esisekelwe nge-Fusion Drives emikhulu (kufika ku-3 TB), noma ubeke esikhundleni se-drives nge-256 GB, 512 GB, noma ama- SSD angu-1 (kuye ngokuthi imodeli ye-iMac).
Olunye ushintsho olusithakazelisayo ekulungiselelweni kwe-Fusion Drive ukuthi i-TB engu-1 ibe nesakhi sayo se-SSD sehlehlisiwe kusuka ku-128 GB kuya ku-24 GB. Ngenkathi lokhu kusekukhulu ngokwanele ukuvumela i-OS nezinhlelo ezimbalwa zezintandokazi zakho ezigcinwe kwisabelo se-SSD esisheshayo seFusion Drive, kusobala ukuthi ayikwazi ukugcina amadokhumenti amaningi nezinhlelo zokusebenza njengenguqulo yangaphambilini.
Kubasebenzisi abangajwayelekile, angiboni ushintsho njengento engalungile. Empeleni kuncishisa izindleko zenketho ye-Fusion ngenkathi inikeza ukunyuswa kokusebenza okugcinwe kwesitoreji. Labo abafuna ukwandisa ukusebenza kwe-Fusion bangakhetha izinketho ezimbili ze-TB noma ezintathu ze-TB, ezisasebenzisa i-128 GB SSD enkulu.
Imemori
Ngenhlanhla, imemori ihlala ivuselelwa ngumsebenzisi, okusho ukuthi ungakwazi ukumisa i-iMac yakho nge-RAM encane kuphela (8 GB), futhi uthuthukise imemori ngokwakho, usebenzisa i-RAM yesithathu engabizi kakhulu. Uma ngabe ngabe i-Apple ingeza i-RAM yakho, inikeza ukuthuthukiswa kuka-16 GB no-32 GB.
I-iMacs yama-27-intshi 2015 isebenzisa imodemu ye-memory ye-1867 MHz ye-DDR3, futhi i-iMac inezinkomba ezine ezifinyelelekayo zomsebenzisi ze-SO-DIMM (ezimbili zilandelwe ngaphambili kwe-8 GB yokucushwa).
Ukuxhumana
I-iMac igcina izinketho ezifanayo zokuxhuma njengamamodeli we-2014. Uzothola i-headphone jack, i- slot ekhadini le-SDXC , amachweba amane e- USB , amabhulo amabili amabili we- Thunderbolt , kanye ne-Gigabit Ethernet eyodwa yegack.
Ukuxhuma okungenantambo kuhlanganisa i-802.11ac, i-Wi-Fi, ne-Bluetooth 4.0.

Izincomo
Isibonelo se-2015 27-inch Retina iMac sinomkhiqizo okhangayo, futhi ngokungafani ne-base iMac engu-21,5-intshi, isebenzisa i-RPM drive esheshayo (7,200), hhayi umshini wokuhamba kancane (5,400 RPM) ovame ukusetshenziselwa kuma-laptops ebhajethi.
I-AMD Radeon R9 M380 ayinayo ukusebenza jikelele kwe-M390 noma i-M395X enikeziwe kwezinye izilungiselelo, kodwa inamandla kakhulu ukushayela ukubukeka kwe-Retac ye-iMac, kanye nanoma yikuphi ukuboniswa okungaphandle kwe-4K ongase uhlanganise.
Uma ungakwazi ukuguqula imali eyengeziwe, ukuthuthukiswa okuwukuphela kwami engingakukhuthaza ukuthi i-iMac eyisisekelo i-1 TB Fusion Drive.
Uma ufuna ukusebenza okuncane, ukusikisela kwami ukuchitha imali ku-processor ye-i7 ukuthuthukisa, ukuze uthole ukusekelwa kwe- hyper-threading evumela ukuthi kufinyelele ku-8 izintambo ukugijima kanyekanye.
Ngokuqondene nehluzo, angikwazi ukuphakamisa ukuthuthukiswa kwe-R9 M395X ngaphandle kokuba unesicelo esithile esingasisebenzisa imemori eyengeziwe eyengeziwe ye-GPU.
