Nasi iMedic 21.5-inch Lineup

Qala kuqala u-21.5-intshi iMac Retina 4K Display

I-Apple ithathe i-wraps off entsha i-iMac lineup engu-21.5-intshi engu-2015 esebenzisa ama -processor ase-Broadwell asekelwe , ihluzo ezihlanganisiwe ze-Intel, futhi, njengoba kulindelwe, imodeli yokubonisa entsha ye-Retina, ekugcineni iletha izinga le-retina lesithombe ezincane ze-iMacs.

I-iMac entshaup engu-21.5 entsha ihlukaniswe ibe yizinhlelo ezintathu eziyisisekelo: imodeli eyisisekelo kanye nephakathi-level, kokubili ukubonisa okujwayelekile kwe-1920 x 1080 esetshenziswe ezizukulwaneni zangaphambilini, nokuhlela okuphezulu okuhlanganisa ukubukwa kwe-Retina 4K, nge-4096 x Amaphikseli angu-2304.

Abacubungula

Sekulinde isikhathi eside, kodwa i-iMacs engu-21 kuya ku-intshi izobe ihlelwe ngamaphrosesa ase-Broadwell asekelwe ku-Intel. Ehlangothini elikhanyayo, ama-chips ase-Broadwell azohlinzeka ngokukhuthaza okuhle ekusebenzeni jikelele, uma kuqhathaniswa neMacs aseHaswell esekelwe. Kodwa ngimangele ukuthi ama- processor esanda kushalwa yi-Skylake , i-Apple engena ku -iMac 27-intshi ka - 2015 , awazange afakwe; lokhu bekuyovumela i-Apple ukuba iqede nje umndeni wase Broadwell.

Ngicabanga ukuthi inkinga yayiyizindleko, njengoba abaproseshi be-Skylake basesimweni esisha kakhulu, futhi baqhubeka beyala kancane imali ephansi. Kodwa-ke, masingatholi sihlanganiswe negama leprosesa, lapho okubaluleke kakhulu ukuthi iMacs entsha izokwenza kanjani.

I-model model isebenzisa i-1.6 GHz Dual-Core i5, kanti iMac mid-level iqhubekela phezulu ku-2.8 GHz Quad-Core i5. Inguqulo ye-Retina ye-iMac engu-21.5-intshi ifika ne-3.1 GHz Quad-Core i5.

I-Retina iMac inikeza ukuthuthukiswa kweprosesa, ikuvumela ukuba uqhube i-processor ku-3.3 GHz Quad-Core i7, okumele inikeze kahle i-punch ku-CPU ukusebenza.

Ama-Graphics

Wonke ama-iMacs angu-21,5-intshi wezi-2015 asebenzisa ihluzo ezihlanganisiwe ezivela ku-Intel. Imodeli eyisisekelo ihambisana ne-Intel HD Graphics 6000, i-GPU efanayo esetshenzisiwe ku- MacBook Air .

Inguqulo ye-Retina ye-iMac engu-21.5-intshi isebenzisa i-Intel Iris Pro Graphics enamandla kunazo zonke 6200. Ngokungafani ne-Retina iMac engu-27 intshi, ayikho ukuthuthukiswa kwegraphic etholakalayo. Kodwa-ke, njengoba i-iMac engu-21.5-intshi isebenzisa ukubonisa okuncane okungu-4K, ngokuhambisana nombukiso we-5K kumfowethu omkhulu, ihluzo ezihlanganisiwe ezingu-6200 kufanele zinikeze ukusebenza kahle kwehluzo, kufaka phakathi ikhono lokushayela kokubili ukubukwa kwe-iMac ka-Retina nokubonisa kwangaphandle kwe-4K exhunywe ngechweba le-Thunderbolt 2.

Isitoreji

Isitoreji esakhiwe ngaphakathi ku-iMacs ka-21,5-intshi ka-2015 yincane yesigxobo esixutshwe. Ukumiswa okujwayelekile kuwo wonke ama-iMacs kuyinkimbinkimbi ye-1 TB efinyelela ku-5,400 RPM. Lokho kukhetha okuhle kwidrayivu yokusekela i-Time Machine, kodwa njengendlela yokuqalisa yokuqalisa, ingaphansi kokuhle. Izinga lokujikeleza eliphansi liqinisekisa ukuqhuma kokusebenza, futhi cishe kuzokubamba amazinyo akho njalo uma uqala i-iMac yakho noma uqalise uhlelo lokusebenza, njengoba ulinde ideskithophu yakho ukuba ivele noma izithonjana zakho zeDock ziyeke ukushaya .

Ngenhlanhla, ungathuthukela ku-version entsha ye-1 TB Fusion Drive noma i- SSD esheshayo njengesitoreji sakho esiyinhloko . I-drive ye-TB ye-Fusion i-1 ihlelwe kancane kancane. Ekuqaleni, i-Fusion drive yenziwe nge-128 GB SSD kanye ne-1 TB drive drive.

Kodwa i-Apple ishintshe i-1 TB Fusion Drive ukuze isebenzise i-24 GB SSD encane kakhulu. Lokhu kufanele kusinike isitoreji esanele ukuqinisekisa ukuthi i-OS X kanye nezinhlelo zokusebenza ezimbalwa ozisebenzisayo kakhulu zigcinwa kwi-SSD ephezulu yokusebenza, kodwa ngeke ishiye ikamelo elengeziwe njengenguqulo yokuqala ye-Fusion Drive. Ehlangothini elikhanyayo, izindleko ze-1 TB Fusion option manje ziphansi kakhulu, futhi ukhetho olu-2 lwe-Fusion lwe-TB lusasebenzisa i-128 GB SSD enkulu.

Ukuxhumana

Akukho kubonakala sengathi kukhona ushintsho ekulungiselelweni kwechweba; i-headphone jack, i-slot ikhadi le-SDXC, amachweba amane e- USB amathathu , amabhulo amabili amabili we- Thunderbolt , kanye nejaji le- Gigabit Ethernet elizungeze ukuxhumana ngemuva kwe-iMac.

Ukuxhuma okungenantambo kuhlanganisa i- 802.11ac Wi-Fi ne- Bluetooth 4.0 .

Izincomo

I-model eyisisekelo ye-iMac 2015-21.5 inexabiso elikhangayo, kodwa ngempela, yilokho ongakusho ngakho. Ihlanganiswe ne-hard drift drive kanye nehluzo eziphakathi. Indawo yayo ekuxhumaneni ukuvumela i-Apple ukuthi ikhangise ngentengo ephansi ezobhena abakhangisi bezinkampani nezemfundo.

Ukuze usebenzise kabanzi, ngincoma imodeli yamanani ephakathi okungewona i-retina eqala ngo-$ 1,299. Kulokhu ngingangezela ukuthuthukiswa kwe-1 TB Fusion Drive (+ $ 100), ukunikeza i-iMac kancane ye-pep nokuhamba ngokuhamba kancane komshini we-5400 RPM osetshenziselwa ukumiswa okuyisisekelo.
