Pavel Jelic Izolo ntambama sibone ukwethulwa kwe-27″ iMac (2020) entsha njengoba bekulindelekile. Sekunesikhathi eside kunamahemuhemu okuthi i-Apple ilungiselela ukwethula ama-iMac amasha. Abanye abavuzayo bathe sizobona ushintsho lokuklama kanye nokuhlelwa kabusha okuphelele, kuyilapho abanye abavuzayo bethi umklamo ngeke ushintshe futhi i-Apple izothuthukisa i-hardware kuphela. Uma ubulokhu uncike kubavuzi eqenjini lesibili ngaso sonke isikhathi, uqagele kahle. Umdondoshiya waseCalifornia unqume ukukushiyela ukwakhiwa kabusha ngokuhamba kwesikhathi, okungenzeka okwamanje lapho sethula ama-iMacs amasha namaphrosesa aso e-ARM. Kepha masisebenze ngalokho esinakho - kulesi sihloko sizobheka ukuhlaziya okuphelele kwezindaba ezivela ku-27 ″ iMac (2020) entsha.
Kungaba njalo okuthakaselayo
U-Vratislav Holub Iphrosesa nekhadi lemifanekiso
Zisuka nje, singakutshela ukuthi cishe zonke izindaba zenzeka kuphela "ngaphansi kwe-hood", i.e. emkhakheni wehadiwe. Uma sibheka amaphrosesa angafakwa ku-27″ iMac (2020) entsha, sithola ukuthi ama-Intel processors akamuva avela esizukulwaneni se-10 ayatholakala. Ekucushweni okuyisisekelo, i-Intel Core i5 enama-cores ayisithupha, imvamisa yewashi engu-3.1 GHz kanye nevelu ye-Turbo Boost engu-4.5 GHz iyatholakala. Kubasebenzisi abafuna kakhulu, i-Intel Core i7 enama-cores ayisishiyagalombili, imvamisa yewashi engu-3.8 GHz kanye nevelu ye-Turbo Boost engu-5.0 GHz iyatholakala. Futhi uma uphakathi kwabasebenzisi abafuna kakhulu futhi abangasebenzisa ukusebenza komcubunguli kuze kufike ezingeni eliphezulu, khona-ke i-Intel Core i9 enama-cores ayishumi, imvamisa yewashi engu-3.6 GHz kanye ne-Turbo Boost engu-5.0 GHz iyatholakala kuwe. Uma okungenani unolwazi oluncane lwama-Intel processors, uyazi ukuthi anenani eliphezulu le-TDP, ngakho-ke angagcina imvamisa ye-Turbo Boost imizuzwana embalwa. I-TDP ephezulu ingesinye sezizathu ezenza i-Apple inqume ukushintshela kumaphrosesa we-ARM we-Apple Silicon.
Igalari yezithombe
Ingxenye yesibili, ebaluleke kakhulu yehadiwe nayo iyikhadi lemifanekiso. Nge-iMac entsha engu-27″ (2020), sinokukhetha ingqikithi yamakhadi emifanekiso amane ahlukene, wonke avela emndenini we-AMD Radeon Pro 5000 Series. Imodeli eyisisekelo ye-iMac entsha engu-27″ iza nekhadi lesithombe esisodwa, iRadeon Pro 5300 enememori engu-4GB ye-GDDR6. Uma ufuna okuthile okungeyona imodeli eyisisekelo, kukhona amakhadi ezithombe e-Radeon Pro 5500 XT anememori engu-8 GB GDDR6, kuyilapho abasebenzisi abadinga kakhulu bangaya kwiRadeon Pro 5700 enenkumbulo engu-8 GB GDDR6. Uma ungomunye wabasebenzisi abadinga kakhulu futhi ungasebenzisa ukusebenza kwekhadi lezithombe kumaphesenti ayikhulu, isibonelo ngesikhathi sokunikezwa, khona-ke ikhadi lemifanekiso le-Radeon Pro 5700 XT elinememori engu-16 GB GDDR6 liyatholakala kuwe. Leli khadi lezithombe liqinisekile ukuphatha ngisho nemisebenzi enzima kakhulu oyiphonsa kulo. Kodwa-ke, kuzodingeka silinde izinsuku ezimbalwa ukuze sithole ubufakazi obuhlobene nokusebenza.
Isitoreji kanye ne-RAM
I-Apple ifanelwe ukunconywa ekugcineni ngokususa i-Fusion Drive esiphelelwe yisikhathi endaweni yokugcina, ehlanganise i-HDD yakudala ne-SSD. I-Fusion Drive iyashesha ukulungisa kulezi zinsuku - uma uke waba nenhlanhla yokuba ne-iMac ene-Fusion Drive kanye ne-iMac ehlanzekile ye-SSD eduze kwenye, uzowubona umehluko emizuzwaneni embalwa yokuqala. Muva nje, ngisho nemodeli eyisisekelo ye-27″ iMac (2020) inikeza i-SSD, ikakhulukazi enosayizi ongu-256 GB. Abasebenzisi abadingayo, nokho, bangakhetha isitoreji esingafika ku-8 TB kusilungisi (njalo siwuphinda kabili usayizi wangempela). Kunjalo, kukhona inhlawulo eyengeziwe yezinkanyezi ukuze uthole isitoreji esengeziwe, njengoba kuwumkhuba enkampanini yakwa-Apple.
Kungaba njalo okuthakaselayo
Ukundiza emhlabeni wonke nge-Apple Ngokuqondene nenkumbulo yokusebenza ye-RAM, kube khona izinguquko ezithile kuleli cala. Uma sibheka imodeli eyisisekelo ye-27″ iMac (2020), sithola ukuthi inikeza kuphela i-8 GB ye-RAM, engeyona eningi namuhla. Kodwa-ke, abasebenzisi bangakwazi ukusetha inkumbulo enkulu ye-RAM, kuze kufike ku-128 GB (futhi, njalo kabili usayizi wangempela). Izinkumbulo ze-RAM ku-27″ iMac (2020) entsha zivulwe ku-2666 MHz ehloniphekile, uhlobo lwezinkumbulo ezisetshenziswayo bese kuthi i-DDR4.

Bonisa
I-Apple ibilokhu isebenzisa isibonisi se-Retina hhayi kuphela kuma-iMacs ayo iminyaka eminingana. Uma ulindele ukuthi i-27″ iMac (2020) entsha ibe noshintsho kubuchwepheshe bokubonisa, wenza iphutha elikhulu. I-retina isetshenzisiwe ngisho namanje, kodwa ngenhlanhla ayinazo izinguquko ngokuphelele futhi i-Apple ilethe okungenani into entsha. Ushintsho lokuqala alulona ushintsho olutheni, kodwa luyinketho entsha kusihleli. Uma uya kusihleli se-27″ iMac (2020) entsha, ungaba nesibonisi sengilazi ephathwa nge-nanotexture efakwe ngenkokhelo eyengeziwe. Lobu buchwepheshe sebenathi izinyanga ezimbalwa manje, i-Apple yaqala ukwethula ngokwethula i-Apple Pro Display XDR. Ushintsho lwesibili bese luthinta umsebenzi we-True Tone, ogcina utholakala ku-27″ iMac (2020). I-Apple inqume ukuhlanganisa izinzwa ezithile kusibonisi, ngenxa yokuthi kungenzeka ukusebenzisa i-True Tone. Uma ungazi ukuthi iyini i-True Tone, isici esihle esishintsha isibonisi sombala omhlophe kuye ngokukhanya okuzungezile. Lokhu kwenza ukuvezwa komhlophe kube ngokoqobo kakhulu futhi kukholekeke.
Kungaba njalo okuthakaselayo
Ikhamera yewebhu, izipikha namakrofoni
Ukuphikelela okude kwabathandi be-apula ekugcineni sekuphelile - i-Apple ithuthukise ikhamera yewebhu eyakhelwe ngaphakathi. Yize iminyaka eminingana emide ngisho nemikhiqizo yakamuva yakwa-Apple inekhamera yewebhu eyakhelwe ngaphakathi ye-FaceTime HD enesixazululo esingu-720p, i-iMac entsha engu-27″ (2020) yeza nekhamera yewebhu eyakhelwe ngaphakathi ye-FaceTime enikezela ngesixazululo esingu-1080p. Ngeke siqambe amanga, akusona isinqumo se-4K, kodwa njengoba besho, "kungcono kunocingo olusesweni". Asethembe ukuthi lesi yisixazululo sesikhashana sokujabulisa abathanda i-Apple, nokuthi ngokufika kwama-iMac aklanywe kabusha, i-Apple izoza nekhamera yewebhu ye-4K, kanye nokuvikelwa kwebhayomethrikhi yobuso be-Face ID - le mojula itholakala kuma-iPhone. Ngokungeziwe kukhamera yewebhu entsha, siphinde sathola izipikha eziklanywe kabusha nemakrofoni. Inkulumo yezikhulumi kufanele inembe kakhulu futhi ama-bass kufanele abe namandla, ngokuqondene nemibhobho, i-Apple ithi ingabhekwa njengekhwalithi yesitudiyo. Ngenxa yazo zonke lezi zici ezintathu ezithuthukisiwe, izingcingo nge-FaceTime zizoba mnandi kakhulu, kodwa izipikha ezintsha zizobongwa abasebenzisi abajwayelekile ngokulalela umculo.

Ngaphezu kwephrosesa eshiwo ngenhla, ikhadi lemifanekiso, i-RAM nesitoreji se-SSD, kunesigaba esisodwa ngaphezulu kusilungisi, okuyi-Ethernet. Kulokhu, ungakhetha ukuthi ingabe i-27″ iMac (2020) yakho izohlonyiswa nge-gigabit Ethernet yakudala, noma uzothenga i-10 gigabit Ethernet ngenkokhelo eyengeziwe. Ngaphezu kwalokho, i-Apple ekugcineni ihlanganise i-chip yezokuphepha ye-T27 ku-2020 ″ iMac (2), enakekela ukubethelwa kwedatha kanye nokuphepha okuphelele kohlelo lwe-macOS ngokumelene nokwebiwa kwedatha noma ukugetshengwa. Kuma-MacBooks ane-Touch ID, iphrosesa ye-T2 nayo isetshenziselwa ukuvikela le hardware, kodwa i-iMac entsha engu-27″ (2020) ayinayo i-Touch ID - mhlawumbe kumodeli eklanywe kabusha sizobona i-Face ID eshiwo ngenhla, ezosebenzisana nayo. ngesandla ne-T2 security chip.
Nansi indlela i-iMac ezayo ene-Face ID engabukeka ngayo:

Inani nokutholakala
Ngokuqinisekile unentshisekelo yokuthi kunjani esimweni se-iMac entsha engu-27″ (2020) enethegi yentengo nokutholakala. Uma unquma ekucushweni okuyisisekelo okunconyiwe, zilungiselele i-54 CZK ejabulisayo. Uma uthanda ukucushwa kwesibili okunconyiwe, lungiselela i-CZK 990, futhi esimweni sokucushwa okunconywayo kwesithathu, kuyadingeka "ukukhipha" i-CZK 60. Vele, lokhu akusho ukuthi le thegi yamanani ingeyokugcina - uma ubungamisa i-iMac yakho entsha engu-990″ (64) ibe phezulu, ingakubiza cishe imiqhele engama-990. Mayelana nokutholakala, uma ukhetha okukodwa kokucushwa okunconyiwe kwe-27″ iMac (2020) entsha namuhla (Agasti 270), khona-ke ukulethwa okusheshayo kuzoba ngomhla ka-5 Agasti, bese ukulethwa kwamahhala kungu-Agasti 27. Uma wenza noma yiziphi izinguquko futhi u-oda i-2020″ iMac (7) elungiselelwe ngokwezifiso izolethwa phakathi no-Agasti 10 - 27. Lesi sikhathi sokulinda asiside neze, ngokuphambene nalokho, samukelekile kakhulu futhi i-Apple isilungile.
