I-New Skylake Processors kunye neNimble Graphics
I-Apple ihlaziye zonke i-iMac lineup ye-2015, kuquka i -iMac yokuqala ye- 21.5-intshi kunye ne-Retina 4K yokubonisa . I-iMac ye-iMac e-27 intshi, nangona kunjalo, ithole i-best of the updates. Kukho i-non-Retina iMacs ukusuka kumgca we-27 intshi. Ukuba uhamba phambili, uya ku-Retina; ubuncinane, oko kubonakala ngathi i-Apple ithatha le nto, kwaye ndivame ukuvumelana.
Kususela ngo-2014 iMac iMic 27 kunye neRetina 5K eboniswayo, sazi ukuba, njenge-MacBook Pro yokuqulunqa, egcina ii-non-Retina imodeli ngexesha elifutshane (kwiimodeli ezingama-13 intshi), ngexesha elide, U-Retina wayekhokela i-Apple yayiza kuhamba kuyo yonke indawo yemveliso.
Ngoko ke, ngaphandle kwayo yonke i-Retina lineup, i-iMac yama-27 intshi i-iMac yafumana izibuyekezo eziphawulekayo eziya ku kholisa nabani na abafuna ukucima ukusebenza ngaphezulu.
I-Retin Display ne-P-Color Space
Masiqale ngokubonisa. Ukuboniswa kwe-Retina yama-27 intshi kungena kwi-5K, nge-resolution ye-pixel ye-5120 x 2880. Umboniso usasebenzisa iphaneli ye-IPS, kodwa entsha kwi-2015 imodeli enkulu ye-DCI-P3 yombala. Isikhundla sombala we-P3 sikhulu, oko kukuthi, siquka indawo enkulu yombala, engavumelekanga kuphela imibala eyongezelelweyo ukuba iboniswe, kodwa imibala enamandla kakhulu. Ukucaciswa kombala we-P3 yinto enye esetyenziselwa iitrafini zedijithali zedijithali, kunye nekhnoloji yokubonakalisa esetyenziselwa imifanekiso yokunyakaza yanamhlanje.
Ukwamkela i-Apple indawo yebala ye-P3 ye-iMac entsha ye-27 intshi ibaluleke kakhulu kulabo abasebenza kwishishini lesithombe eshukumisayo, kunye nabani na osebenza kwimveliso yevidiyo. Ngasekupheleni kuka-2014, bekukho kuphela izilwanyana eziqinisekisiweyo ze-P3 ezifumanekayo kubaqeqeshi, kwaye ngeendleko ezininzi, ngaphezu kweMac.
Ngoko, uyabona indlela iMac entsha yokubonisa ngayo i-P3 5K iya kuba yintle.
Abaprofeti
Kwi-iM-27 yamasentimitha angama-intshi, i-Apple yehla iprojekthi ye- Broadwell yesizukulwana sesihlanu , kwaye yahamba ngqo kwiimodeli zangoku zase Skylake . I-iMacs yama-27 yamasentimitha ama-27 anikwe iiprosesa ze-3.2 kunye ne-3.3 ze-Quad-Core i5, kunye nokuphuculwa kwe-4.0 GHz Quad-Core i7.
Iimodeli ezisekelwe kwi-i7 zikwazi ukuqhuba iifayili ezifanayo ezi-8, ngokukodwa zilinganisa ukusebenza kwe-CPU eyi-8.
Iprojekthi entsha ye-Skylake ayinikezeli amandla okwenziwa kwiimodeli ezisekelwe kwi-Broadwell, kodwa ukususela ekubeni i-Apple inqabile ngaphezu kwe-Broadwell, iprojekthi ze-Skylake kufuneka zivelise ukuxuma okuhle kwi-iMacs ye-2014 eyayisebenzisa iprogram ye-Haswell.
Inzuzo eyongezelelweyo yabalingisi be-Skylake kukuba banamandla okomeleleyo, baqhuba ukupholisa xa beqhubeka nokubonelela ngokunyusa ukusebenza. Xa unesibonakaliso esikhulu se-Retin 27-intshi, ukugcina i-insides ye-Mac yakho epholile kubaluleke kakhulu.
Imifanekiso
I-iMacs yama-27-intshi iMacs i-AMD Radeon R9 GPU kwizinto ezintathu zokuqwalasela: i-R9 M380 kunye ne-2 GB yememori ye-GDDR5; R9 M390, kunye ne-2 GB yememori ye-GDDR5; kunye ne-R9 M395 kunye ne-2 GB yememori ye-GDDR5. Kukho ukhetho lwe R9 M395X kunye ne-4 GB yememori ye-GDDR5.
Naliphi na i-AMD GPU izakuqhuba ngokukhawuleza isibonakaliso se-5K kwaye iqhubeke isinika amaninzi amaninzi abasebenzisi abaninzi. Ukuba ngokuyinhloko ucinga ukusebenzisa i-iMac yokunikezela ngomfanekiso kunye nevidiyo, i-R9 M395X kunye nenkumbulo enkulu inokuba nomdla. Kodwa ininzi yethu, kuquka abo banokuzibuza ngokusebenza komdlalo, kufuneka bafumane i-R9 M390 ngaphezulu kunokwaneleyo.
Ukugcina
I-iMac enkulu yama-27 intshi inamathuba athile ngenxa yobukhulu bayo bobukhulu, okwenza ukupholisa ingaphakathi kube lula kunamamodeli angama-21,5-intshi iMac. Enye yezi nzuzo kukuba nokuba isitoreji esisezantsi sisebenzisa i-1 TB 7200 RPM drive. Isantya sokujikeleza ngokukhawuleza senza ukuba i-hard drive ye-TB ephambili isetyenziswe kwisistim esisiseko esisebenzisekayo kubasebenzisi abaninzi.
Ukuba unyuke ukuya kuma-middle or top tier models, uza kufumana i-TB ye- Fusion Drive okanye i-2 TB Fusion Drive njengomgangatho ophantsi. Unokuphucula ukugcinwa kwesiseko kunye nee-Fusion Drives ezinkulu (ukuya kwi-3 TB), okanye ubeke endaweni yokuqhuba ii-256 GB, 512 GB, okanye ii-SSD ze- 1 ze-TB (kuxhomekeke kwimodeli yeMac).
Olunye utshintsho olushukumisayo kwiinkqubo zeFusion Drive kukuba i-1 TB inguqu ye-SSD iye yahlahla ukusuka kwi-128 GB ukuya kwi-24 GB. Nangona oku kusekukhulu ngokwaneleyo ukuvumela i-OS kunye nezinye ezimbalwa zezintandokazi zakho zokusebenza ukuba zigcinwe kwisabelo se-SSD esheshayo seFusion Drive, ngokucacileyo ayikwazi ukugcina amanqaku amaninzi kunye neenkqubo njengenguqu yangaphambili.
Kubasebenzisi abangasetyenziswayo, andiyikubona utshintsho njengento engalunganga. Ngokwenene kuncitshisa iindleko zenketho yeFusion ngelixa lisaqhubeka nokunyusa ukunyuswa komsebenzi. Abo bafuna ukwandisa ukusebenza kwe-Fusion bangakhetha i-2 TB okanye i-3 TB ongakhethayo, esasisebenzisa i-128 GB SSD enkulu.
Imemori
Ngombulelo, imemori ihlala isetyenziselwa ukuhlaziywa komsebenzisi, oku kuthetha ukuba unokuqwalasela i-iMac yakho kunye ne-RAM encinci (8 GB) kunye nokuphucula imemori ngokwakho, usebenzisa i-RAM yesithathu engabizi. Ukuba ungathanda ukuba i-Apple idibanise i-RAM, inika i-GB ne-32 GB yokuphucula.
IMacs yama-27-intshi 2015 isebenzisa iimodyuli zeememori zeememori ze-1867 MHz zeDDR3, kwaye i-iMac ineememori ezine ezifikelelekayo zomsebenzisi ezifumaneka kwi-SO-DIMM (ezimbini zilandelwa ngaphambili kwi-8 GB yoqwalaselo).
Ukudibanisa
I-iMac igcina izinto ezifanayo zokuxhamla njengemizekelo ye-2014. Uza kufumana i-headphone jack, i- slot ye-SDXC yekhadi , ii- USB ezintathu zokungena , ii- Two Thunderbolt ii-port , kunye ne-one Gigabit Ethernet jack.
Uxhumano lwe-Wireless luquka i-802.11ac, i-Wi-Fi kunye ne-Bluetooth 4.0.

Iingcebiso
Umzekelo wesiseko we-2015 27-intshi i-Retina iMac inexabiso elikhangayo, kwaye ngokungafani ne-base iMac 21.5-intshi, isebenzisa i-RPM drive esheshayo (7,200), kwaye ayikho i-slow-drive (5,400 RPM) esetyenziswa rhoqo kwii-laptops zebhajethi.
I-AMD Radeon R9 M380 ayinayo yonke into eyenziweyo ye-M390 okanye iM395X enikezelwa kwezinye iilungiselelo, kodwa iyakwazi ukuqhuba ukubonakaliswa kwe-iMac ye-Retina, kunye nayo nayiphi na enye yangaphandle ibonakaliso lwe-4K onokubambisana.
Ukuba unako ukuguqula imali eyongezelelweyo, ukuphuculwa okuphelayo endingayincoma ukuba iMac isiseko yi-1 TB Fusion Drive.
Ukuba ukhangele ukusebenza kancinci, isicetyhulwa sam ukuchitha imali kwi-processor ye-7 yokuphucula, ukufumana inkxaso yokuxhumela i-hyper-threading evumela i-thread ye-8 ukuba isebenze ngokukhawuleza.
Ngokuphathelele imifanekiso, andinakucebisa ukuphuculwa kwe-R9 M395X ngaphandle kokuba unesicelo esithile esingasetyenziswa kwimemori engaphezulu kwi-GPU.
