Nidaamka Cusub ee Skilake iyo Nimble Graphics
Apple wuxuu soo cusbooneysiiyey dhammaan qaybta iMac ee 2015, oo ay ku jiraan 21.5-inch iMac oo leh bandhig bandhigga Retina 4K . Qeybta 27-inch ee iMac, si kastaba ha ahaatee, waxay heleen ugu fiicnaanta casriyeynta. Goonku waa iMacs aan ahayn Retina oo ka soo jeeda qeeybta 27-inch. Haddii aad weynayso, waxaad ku socotaa Retina; ugu yaraan, waxay u egtahay in Apple ay qaadato arinta, waana aan isku raacsanahay.
Ilaa tan iyo 27-inch iMac oo leh Retina 5K Sawir ah ayaa la sii daayay, waxaan ognahay in, sida MacBook Pro, oo ah qaababka non-Retina ee mudada gaaban (oo ah 13-inch), muddada dheer, Retina wuxuu ahaa jihada Apple wuxuu ka gudbi lahaa dhamaan badeecada wax soo saarka.
Sidaas darteed, marka laga reebo dhammaan Retina lineup, 27-inch iMac waxay heshay qaar ka mid ah casriyadoodii muhiimka ah ee ku farxi lahaa cid kasta oo dooneysa in ay iska dhejiso waxqabadka.
27-inch Retina Display oo leh P3 Color Space
Aynu bilawno bandhigga. Shirkadda 27-inch Retina ayaa weli ku jirta 5K, iyadoo leh 5120 x 2880 pixel pixel. Muuqaalku wuxuu wali isticmaalayaa guddi IPS, laakiin cusub ee loogu talagalay 2015-ka waa midka ugu ballaaran ee DCI-P3 gamut. Muuqaalka midabka P3 waa mid ka weyn, taas oo ah, waxay ka kooban tahay meel ballaaran oo midab leh, taas oo u oggolaaneysa midabada dheeraadka ah ee lagu soo bandhigi karo, laakiin midabyo badan oo firfircoon. Qeexitaanka midabka P3 waa isku mid loo isticmaalo tiyaatarka filimka digital, iyo farsamaynta qiyaasta loo isticmaalo sawirrada casriga casriga ah.
Apple ee korsashada P3 midabka cusub ee 27-inch iMac waa mid aad u muhiim u ah kuwa ka shaqeeya warshadaha sawirka, iyo sidoo kale qof kasta oo ka shaqeeya wax soo saarka fiidiyowga. Laga soo bilaabo dhammaadka sannadka 2014, waxaa jiray kaliya kormeerayaal P3 oo haysta shahaadooyin haysta oo loo heli karo xirfadlayaal, iyo kharash aad u badan, si ka sarreeya oo si buuxda loo xakameeyo iMac.
Sidaa darteed, waad arki kartaa sida iMac cusub oo leh qaab sawir leh P3 5K waa mid aad u soo jiidasho leh.
Gormeerayaal
Ipad 27-inch oo ka mid ah IMac, Apple ayaa ka goosatay jadwalka shanaad ee jiilka Broadwell , waxayna u socotay moodooyinka ugu badan ee Skylake . The 27-inch iMacs 2015 waxay u dhigantaa 3.2 iyo 3.3 Gacaliye Quad-Core i5, iyada oo la cusbooneysiiyo oo la heli karo oo ah 4.0 GHz processor Quad-Core i7.
Moodooyinka ku salaysan i7 waxay awood u leeyihiin in ay ku shaqeeyaan ilaa 8 wada xiirood oo isdhaafsan, iyagoo si dhab ah u dheelitiraya waxqabadka 8-maadada CPU.
Qalabyada cusub ee Skylake ma siinayaan kor u kac weyn oo ku salaysan qaababka Broadwell-ku salaysan, laakiin tan iyo markii Apple uu ka boodey Broadwell, waa inay soo saaraan hufnaan fiican oo ka soo baxda 2014 iMacs kaas oo isticmaaley Processor Processor.
Faa'iido dheeraad ah oo ka mid ah nidaamyada Skylake waa in ay yihiin tamar badan oo tamarta, qaboojiyaha sii wadaya iyada oo weli la siinayo kor u qaadida waxqabadka. Markaad leedahay muuqaal aad u sarreeya oo 27-inch Retina ah, adigoo ku haysanaya mawduucyadaada Mac Macmiilku waa tixgelin muhiim ah.
Graphics
The 27-inch iMacs oo isticmaala AMD Radeon R9 GPUs saddexda haboon: R9 M380 oo leh 2 GB of GDDR5 xasuusta; R9 M390, oo sidoo kale leh 2 GB oo GDDR5 ah; iyo R9 M395 oo leh 2 GB oo GDDR5 ah. Waxaa sidoo kale jira ikhtiyaari R9 M395X oo leh 4 GB oo GDDR5 ah.
Mid kasta oo ka mid ah GP-yada AMD waxay si sahlan u wadi doonaan shaashadda 5K waxayna weli siinaysaa muruqyo badan oo loo adeegsado inta badan dadka isticmaala. Haddii aad inta badan ku fikirtid adigoo isticmaalaya iMac oo sawir iyo muuqaal muuqaal ah, R9 M395X oo leh xasuusta weyn ee laga yaabo inay tahay mid xiiso leh. Laakiin inta badan naga mid ah, kuwaas oo ay ku jiraan kuwa laga yaabo inay ka yaabaan waxqabadka ciyaarta, waa in ay helaan R9 M390 wax ka badan oo ku filan.
Kaydinta
27-inch iMac oo waaweyn ayaa leh waxoogaa faa'iido leh sababtoo ah qiyaasta jireed, taas oo ka dhigaysa in la qaboojiyo gudaha gudaha fudud ka badan moodooyinka 21.5-inch iMac. Mid ka mid ah faa'iidooyinkaas ayaa ah in xitaa kaydinta aasaasiga ah ay isticmaasho isticmaalka 1 TB 7200 RPM gaari. Heerka wareega ee degdega ah ayaa xitaa xitaa darawalnimada 1aad ee TB-da ee loo isticmaalo qaabka asaasiga ah ee loo adeegsado badi dadka isticmaala.
Haddii aad kor u qaadatid qaababka dhexe ama midka sare, waxaad ka heli doontaa 1 TB Fusion Drive ama 2 TB Fusion Drive sida heerka ugu hooseeya. Waad kordhi kartaa kaydinta saldhigyada leh Fujiyado waaweyn oo qulqulaya (illaa 3 TB), ama waxaad ku bedelan kartaa 256 GB, 512 GB, ama 1 TB SSD (waxay ku xiran tahay nooca iMac).
Mid ka mid ah isbeddelka xiisaha leh ee Fusion Drive waa qaababka 1-da ah ee TB-da ayaa qaybteeda SSD hoos u dhigtay 128 GB ilaa 24 GB. Inkastoo tani ay tahay mid wali ku filan in ay u oggolaato OS iyo dhawr ka mid ah barnaamijyada aad jeceshahay in lagu keydiyo qaybta SSD ee Fusion Drive, waxa muuqata inaanu kaydin karin dukumintiyada iyo barnaamijyada badan sidii hore.
Isticmaalaha casriga ah, ma arko isbeddelka inay tahay wax xun. Xaqiiqdii waxay yareyneysaa kharashka Fusion-ka marka la sii wado sii kordhinta waxtarka kaydinta. Kuwa doonaya inay sare u qaadaan waxqabadka Fusion waxay dooran karaan 2-da Tiibayda ama 3-aad ee TB-da, taas oo wali isticmaaleysa 128 GB SSD.
Xusuusin
Nasiib wanaag, xusuusta waxay ku jirtaa isticmaalaha la cusbooneysiin karo, taas oo macnaheedu yahay inaad iMac-gaaga u qaabeyn karto oo kaliya RAM-ka ugu yar (8 GB), isla markaana cusbooneysii xasuusta adigoo adeegsanaya adigoo adeegsanaya RAM ka jaban. Haddii aad doorbidi laheyd in Apple laguugu daro RAM, adiga ayaa ku siinaya 16 GB iyo 32 GB oo casriyeyn ah.
The 27-inch 2015 iMacs waxay isticmaalaan qalabka xusuusta ee 1867 MHz DDR3, iMac waxay leedahay afar meelood oo la isticmaali karo SO-DIMM oo isticmaali kara (laba ayaa horay loogu soo dhejiyay qaabka 8 GB).
Isku xirnaanta
IMac waxay haysaa fursado isku mid ah isku xirnaanta moodooyinka 2014-ka. Waxaad ka heli doontaa jaakad dhagax, kaar SDXC , afar meelood oo 3 USB ah , laba dekedood oo xudduud ah , iyo lafdhab Gigabit Ethernet jack.
Isku xirnaanta wireless waxaa ka mid ah 802.11ac, Wi-Fi, iyo Bluetooth 4.0.

Talooyin
Qaabka aasaaska ee 2015-ka ee 27-inch Retina iMac wuxuu leeyahay qiimo soo jiidasho ah, oo ka duwan salka 21.5-iMac, wuxuu isticmaalaa dhakhso ah (7,200) RPM wadada, mana aha gaabis (5,400 RPM) baabuur si caadi ah loo isticmaalo laptops miisaaniyadeed.
AMD Radeon R9 M380 ma laha waxqabadka guud ee M390 ama M395X oo lagu bixiyay qaababka kale, laakiin waxay awood u leedahay inay ku soo qaadato iMac's Retina display, iyo sidoo kale bandhigyada kale ee 4K ee aad ku xiran karto.
Haddii aad kicin karto lacagta caddaanka ah, kor u qaadida keli ah ee aan ku talin lahaa saldhigga iMac waa 1 TB Qalabka Fusion.
Haddii aad raadinaysid waxoogaa waxqabad oo dheeraad ah, soo jeedintaydu waa inay lacag ku qaadato kor u qaadida i7, si ay u hesho taageerada hyper-threading oo u oggolaanaysa ilaa 8 xariirood in ay ku dhowaadaan isla markiiba.
Sida shaxanka, ma ku talin karaa hagaajinta R9 M395X ilaa aad haysato codsi gaar ah oo ka dhigi kara isticmaalka GPU ee xasuusta dheeriga ah.
