New Skylake Processors le Nimble Graphics
Apple e ntlafalitse eohle iMac lineup ea 2015, ho akarelletsa le iMac ea 21,5-inch e nang le ponahalo ea Retina 4K . IMac ea 27-inch e lekana, leha ho le joalo, e fumane molemo ka ho fetisisa oa liphetoho. Ha e le hantle li-iMacs tseo e seng tsa Retina tse tsoang boemong ba 27-inch. Haeba u e-ea kholo, u ea Retina; bonyane, ho bonahala eka Apple e nka taba ena, 'me ke atisa ho lumellana.
Ho tloha ha iMac ea 2014 e nang le lichitha tse 27 le Retine 5K e hlahisitsoe, re ne re tseba hore, feela joaloka MacBook Pro lineup, e neng e boloka mehlala e se nang Retina bakeng sa nako e khutšoanyane (ka mehlala ea 13-inch), nako e telele, Retina e ne e le tataiso ea hore Apple e tla feta hohle sehlahisoa sa sehlahisoa.
Ka hona, ntle le ts'ebetso ea Retina eohle, iMac ea 27-inch e fumane lisebelisoa tse bohlokoa tse tla khahlisa motho leha e le ofe ea batlang ho pata ts'ebetso e eketsehileng.
Retin Display Display le P3 Colour Space
A re qaleng ka pontšo. Tlhahiso ea Retina ea 27-inch e sa ntse e fihla ka 5K, e na le qeto ea pixel ea 5120 x 2880. Pontšo e sa ntsane e sebelisa phapa ea IPS, empa e ncha bakeng sa mehlala ea 2015 ke e kholoanyane ea DCI-P3 mmala o motle. P3 mmala sebaka se seholoanyane, ke hore, se kenyeletsa sebaka se seholoanyane sa mebala, se lumelle feela mebala e eketsehileng e lokelang ho bontšoa, empa le mebala e mengata e matla. Tlhaloso ea 'mala oa P3 ke eona e sebelisetsoang libaesekopo tsa lifilimi tsa digital, le theknoloji e bonts'ang e sebelisetsoang litšoantšo tsa mehleng ea kajeno.
Ho amoheloa ha Apple sebaka sa P3 bakeng sa iMac e ncha ea 27-inch ke ea bohlokoa haholo ho ba sebetsang indastering ea litšoantšo tse tsamaeang, hammoho le mang kapa mang ea sebetsang lihlahisoa tsa video. Ho fihlela ka 2014, ho ne ho e-na le lihlopha tse fokolang tse nang le P3 tse fumanehang ho litsebi, le ka litšenyehelo tse ngata, ka holimo ho iMac e qhekelitsoeng ka botlalo.
Kahoo, o ka bona kamoo iMac e ncha e nang le ponelo ea P3 5K e tla ba e khahlehang kateng.
Lisebelisoa
Ka iMac e nang le li-27-inch, Apple e ile ea theola mekhoa ea pele ea Broadwell ea moloko oa bohlano , 'me ea fihla mehlala ea Skylake ka ho fetisisa. Macs ea 2015 e nang le lichitha tse 27 e na le lisebelisoa tsa 3.2 le 3.3 tsa Quad-Core i5, tse ntlafetseng tse fumanehang ho bathetsi ba 4.0 GHz Quad-Core i7.
Mefuta e i7 e thehiloeng ho i7 e na le bokhoni ba ho sebelisa likhoele tse 8 tse kopanetsoeng, e le ho etsisa ts'ebetso ea CPU e 8.
Liphetoho tse ncha tsa Skylake ha li fane ka ts'ebetso ea bohlokoa ho ts'ebeliso ea mehlala ea Broadwell, empa ho tloha ha Apple a tlohela Broadwell, basebelisi ba Skylake ba lokela ho hlahisa mekhoa e metle mosebetsing ka lebaka la li-iMacs tsa 2014 tse sebelisang provense ea Haswell.
Molemo o eketsehileng oa li-processla tsa Skylake ke hore li matla haholoanyane, li sebetsa li pholile ha li ntse li fana ka ts'ebeliso ea ts'ebetso. Ha o na le ponahalo e kholo ea Retina ea 27-inch, ho boloka li-insides tsa Mac ea hao li pholile ke ho nahanisisa ka bohlokoa.
Litšoantšo
Macs ea 2015 e nang le li-inch tse 27 e sebelisa AMD Radeon R9 GPUs ka litlhophiso tse tharo: R9 M380 le 2 GB ea GDDR5 khopotso; R9 M390, hape le 2 GB ea GDDR5 khopotso; le R9 M395 le 2 GB ea GDDR5 khopotso. Hape ho na le khetho bakeng sa R9 M395X ka 4 GB ea GDDR5 khopotso.
Leha e le efe ea GPU ea AMD e tla khanna ponahalo ea 5K habonolo 'me e ntse e fana ka mesifa e ngata ea ho fetola basebelisi ba bangata. Haeba u nahana ka ho sebelisa iMac bakeng sa phetolelo ea setšoantšo le video, R9 M395X le mohopolo o kholoanyane e ka ba oa thahasello. Empa boholo ba rona, ho kenyeletsa le ba ka 'nang ba ipotsa ka tshebetso ea papali, ba lokela ho fumana R9 M390 ho feta ho lekaneng.
Boloka
IMac e kholoanyane ea 27-inch e na le menyetla e itseng feela ka lebaka la boholo ba 'mele, e leng se etsang hore ho phomola ka hare ho hare ho feta mefuta ea iMac ea 21,5-inch. E 'ngoe ea melemo ena ke hore esita le polokelo ea motheo e sebelisa 1 TB 7200 RPM drive. Lebelo le potlakileng la ho potoloha le etsa hore ho be le sebaka se tloaelehileng sa 1 TB se sebelisoang mothating oa motheo o sebelisoang ho basebelisi ba bangata.
Haeba o nyolohela ho mehlala ea bohareng kapa ea holimo, o tla fumana 1 TB Fusion Drive kapa 2 TB Fusion Drive e le tekanyetso e tlaase. O ka ntlafatsa setsi sa polokelo le li-Driving Fusion tse kholoanyane ho fihlela ho 3 TB, kapa u nkela libaka tse 256 GB, 512 GB, kapa SSD ea 1 TB (ho latela iMac model).
Phetoho e 'ngoe e thahasellisang ka litokisetso tsa Fusion Drive ke hore phetolelo ea 1 TB e na le karolo ea SSD ea eona e theohile ho tloha ho 128 GB ho ea ho 24 GB. Ha sena se sa ntse se lekana ho lumella OS le tse seng kae tsa li-app tsa hau tseo u li ratang hore li bolokoe karolong e potlakileng ea SSD ea Fusion Drive, ho totobetse hore e ke ke ea boloka mangolo le lisebelisoa tse ngata joaloka phetolelo e fetileng.
Bakeng sa basebelisi ba tloaelehileng, ha ke bone phetoho e le e mpe. E hlile e fokotsa litšenyehelo tsa khetho ea Fusion ha e sa ntse e fana ka ts'ebetso e phahameng ea polokelo ea ts'ebetso. Ba batlang ho eketsa ts'ebetso ea Fusion ba ka khetha khetho ea 2 TB kapa 3 TB, e ntseng e sebelisa 128 GB SSD e khōloanyane.
Khopotso
Ka lehlohonolo, moemori o ntse o ntlafatsoa ke user, e bolelang hore o ka lokisa iMac ea hau ka bonyane feela RAM (8 GB), 'me u ntlafatse mohopolo ka boeena, u sebelise RAM e sa theko e tlaase. Haeba u ka rata hore ebe Apple e eketsa RAM bakeng sa hau, e fana ka lintlafatso tse 16 GB le 32 GB.
Macs ea 27-inch 2015 e sebelisa mekhoa ea memo ea memo ea 1867 MHz DDR3, mme iMac e na le mohopolo oa mefuta e mene ea SO-DIMM e fumanehang (tse peli li etselitsoe pele ho 8 GB configuration).
