Daniel Hruska Saqala ukubona isibonisi se-Retina ku-iPhone 4 ngo-2010. Ngemva kwalokho, isibonisi esinesinqumo esiphezulu safika kumathebulethi e-iPad sadlulela ku-MacBook Pro. Namuhla, i-Apple yethule ikhompyutha yedeskithophu ye-iMac engu-27-intshi emhlabeni, enesibonisi esinokulungiswa okuhloniphekile kwe-5K.
Uma ufuna ukwazi izinombolo eziqondile, isinqumo samaphikseli angu-5120 x 2880, okwenza i-iMac ibe ngumholi ophelele phakathi kwamadeskithophu. Amaphikseli ayizigidi ezingu-14,7 - yilawo kanye inani ozowathola kusibonisi esingama-intshi angu-27. Ungadlala amamuvi ayisikhombisa e-Full HD eceleni noma uhlele ividiyo ye-4K futhi usenendawo eningi kudeskithophu yakho.
Iphaneli yonke iqukethe izendlalelo ezingu-23 ezithatha amamilimitha angu-1,4 kuphela. Ngokwamandla, isibonisi esisha se-Retina 5K sisebenza kahle ngo-30% kunesibonisi esijwayelekile esinikezwe ku-iMac engu-27-intshi. I-LED isetshenziselwa ukukhanya kwangemuva, isibonisi ngokwaso senziwe nge-TFT (i-transistor yefilimu encane) esekelwe ku-oxide, okungukuthi i-Oxide TFT.
Njengoba isibonisi se-Retina 5K siqukethe amaphikseli aphindwe izikhathi ezi-4 kunesibonisi se-iMac yangaphambilini, bekudingeka ukuthi kushintshwe indlela yokuqondisa. Ngakho-ke i-Apple kwadingeka ithuthukise eyakhe i-TCON (isilawuli sesikhathi). Ngenxa ye-TCON, i-iMac entsha ingakwazi ukuphatha kalula ukusakazwa kwedatha nge-throughput engu-40 Gb ngomzuzwana.
Emaphethelweni, i-iMac ingamamilimitha angu-5 kuphela ubukhulu, kodwa vele iqhuma phakathi ukuze ikwazi ukuthwala yonke ihadiwe. Imishini eyisisekelo ye-iMac ithole iphrosesa ye-Intel Core i5 eyi-quad-core enejubane lewashi elingu-3,4 GHz, ngemali eyengeziwe i-Apple izonikela nge-4 GHz i7 enamandla kakhulu. Womabili amaphrosesa anikela ngeTurbo Boost 2.0, ekhulisa ngokuzenzakalelayo ukusebenza noma nini lapho kudingeka.
I-AMD Radeon R9 M290X enenkumbulo engu-2GB DDR5 inakekela ukusebenza kwezithombe, futhi ngemali eyengeziwe ungathola i-AMD Radeon R9 M295X enememori engu-4GB DDR5. Ngokuqondene nememori yokusebenza, i-8 GB (1600 MHZ, DDR3) izonikezwa njengesisekelo. Izikhala ezine ze-SO-DIMM zingase zifakwe kufika ku-32GB wememori.
Uthola u-1 TB wesitoreji se-Fusion Drive sedatha yakho. Ungakwazi ukumisa kufikela ku-3TB Fusion Drive, noma 256GB, 512GB noma 1TB SSD. Ngeke uthole ama-hard drive ajwayelekile ku-iMac anesibonisi se-5K Retina, futhi akumangazi nhlobo.
Futhi manje ngokuxhumeka - ujeke ongu-3,5mm, i-4x USB 3.0, i-slot yememori ye-SDXC, i-2x Thunderbolt 2, i-45x RJ-4.0 ye-gigabit ethernet nesikhala sokukhiya i-Kensington. Kusuka kubuchwepheshe obungenawaya, i-iMac isekela i-Bluetooth 802.11 ne-Wi-Fi XNUMXac.
Ubukhulu bekhompiyutha (H x W x D) buyi-51,6 cm x 65 cm x 20,3 cm. Isisindo sibe sifinyelela ku-9,54 kilograms. Ngaphezu kwe-iMac ngokwayo, iphakheji ihlanganisa ikhebula lamandla, i-Magic Mouse nekhibhodi engenantambo. Intengo iqala ngo Isitolo se-Apple Online emiqheleni engu-69.
69 :-)
I-Apple ine-calculator ethokozisayo :D
Ingabe usho ukuthi ulindele isimo sebhizinisi esibi kakhulu eYurophu? Isib. iwaranti eyisibopho yeminyaka emibili inyusa izindleko kanjalo nenani. Engeza isivikelo esithile ekushintshashintsheni kwezinga lokushintshisana kanye ne-VAT engu-21% enonya, kanye nesilinganiso esingu-1USD=1EUR sesivele sinengqondo.
Uma ngikhumbula kahle e-USA intengo izoba ngu-52 CZK.
Izintengo zase-US zihlala zicashunwa ngaphandle kwentela. Ngakho phindaphinda i-USD 2499 ngenani lokushintshanisa, engeza u-21% we-VAT yase-Czech emphumela, futhi uku-65. CZK
Uma uthenga e-US nge-inthanethi futhi uyithumele kwelinye izwe ngaphandle kwalelo lapho kuhlala khona i-e-shop, intela ayikhokhwa. Futhi wonke amazwe anentela ehluke kancane, ngisho efinyelela ku-4-5%, uma kuqhathaniswa ne-Czech Republic, iyipharadesi...
UJirka: Ngokubona kwami, uhlala ukhokha intela yezwe lapho izimpahla zithunyelwa khona, noma ezimeni lapho ngithenga okuthile, kwakuhlale kunjalo, intela ihlukile kuzo zonke izifundazwe. Kunoma ikuphi, uma ungathanda ukuyingenisa ngokusemthethweni (ngiqonde ukuthi kunzima ukufaka i-iMac emthwalweni wakho siqu endizeni bese uwushushumbisa), bese ukhokha intela ye-CZ futhi ekugcineni uzoba nayo isamba semali esifana kakhulu nenani elisohlwini lwe-Czech, futhi ngaphezu kwalokho, kuphela ngewaranti yonyaka owodwa.
…ubuningi obungu-4-5%? Lokho cishe kunzima ... nje i-google "intela yokuthengisa".
Cishe ngeke kube nesibonisi esihlukile okwamanje. Shame :(
Akukho okungaxhunywa kuyo :-) I-Thunderbolt 2 ayikwazi ukudlulisa isinqumo esinjalo :-) kuze kube yilapho ukuduma kwezulu okusha kungakwenza ... impela ikhona indlela yokukuzungezile .. bekungaba kwanele uma isibonisi sibheka njengezibonisi ezimbili bese ukuduma kwezulu kuzokwazi ukudlulisa ... kodwa ngeshwa ... kubonakala sengathi kuze kube yilapho amadivaysi alandelayo azokwazi ukusebenza ngesibonisi se-2K
Ngisho nokuduma kokuqala kuhlale kunokugeleza kwedatha okwanele, kungasaphathwa okubili. Ngicabanga ukuthi isibuyekezo nje kuphela, akunjalo?
Ukusakazwa kwedatha kuyinto eyodwa futhi isignali yevidiyo ingenye :-) I-Thunderbolt 2 ingadlulisela kuphela ividiyo efika ekulungisweni kwe-4K kumonitha eyodwa...
uma kunjalo, badumale kakhulu ngokuthi abazange babhale izinga elingakwazi ukuliphatha noma abazange bafake uhlu lokuqapha ku-4K esikhundleni salokho.
Kunezinketho eziningi lapha futhi akukho okuhle:
– isibonisi esihlukile sizohlala ekulungisweni kwesilinganiso esincane sanamuhla
- isibonisi esihlukile se-4K sizoba nesinqumo esingcono kune-iMac
- isibonisi esihlukile esingu-5K asikwazi ukuxhunywa ku-Mac Pro ne-Mac Mini yamanje
Kulungile, yimi ngedwa othola ukulungiswa kwe-Intel Core i5 (3,5GHz) kanye ne-8GB RAM (imvamisa?) ye-Retina iMac kuhlekisa kakhulu :D Futhi, ukushintshela ku-Radeons njengoba nje uNvidia ethule i-GTX 970 ne-GTX 980 - ngokuyisisekelo amakhadi angcono kakhulu ekilasi "labathengi"...
Abenzanga okuningi ngalokhu, ngaphandle kwesibonisi, engikubheka njengokungasizi - ngihlezi phambi kwe-27″ iMac min 2010, ngakho-ke ngingahlulela ukuthi ukuminyana kwephikseli kwanele. Isibonisi singase sibe sihle ekuhleleni ividiyo ye-4k, kodwa enye ingxenye yehadiwe imfushane ngakho, futhi uma nginekhamera engu-4k, cishe ngizothola i-Mac Pro okwamanje.
Hhayi-ke, okungenani kungiqinisekise ukuthi ngakhe i-Hackintosh: i-intel Core i7 4790K (I-Overclocked to approx. 4,7 GHz), Nvidia GTX 970 SC, 32 GB RAM (2400 MHz), 2× 512 GB SSD ku-RAID0... Inani mayelana $2000
Ngicabanga ukuthi ukucushwa kuhamba kahle, angifuni nje ukusebenzisa ama-NVIDIA amasha njengoba ubhala.
Kubukeka kulungile nakimi. Okusho ukuthi, ngaphandle kwe-8 GB ye-RAM kusisekelo, lapho iMacbook Pro 15″ ine-16.
I-iMac inenzuzo yokuba umsebenzisi esikhundleni. Futhi kushibhe kakhulu ukuwathenga emakethe kunaku-Apple :-)
Awu, lokho kuhle ngempela. Njengoba bebeshintshwa ku-MBP, bekulula ukungena kuyo futhi kunengqondo, ngizenzele ngokwami. Kepha hlobo luni lwesiwula oluzolala ngesibonisi ngenxa ye-RAM eshibhile ku-iMac?
Ku-27″ iMac, ashintsha ngokujwayelekile ukusuka ngemuva. Sebenza imizuzu embalwa. Futhi ngokolwazi olukuwebhusayithi ye-Apple, ngizoshintsha kanje ku-iMac retina.
Njengoba i-dfx isho - USER
Ekuhlelweni kwevidiyo, amaRadeons angcono kuneNvidia. Banokusebenza okungcono kakhulu ku-OpenCL, esetshenziswa isb.
Ngihlela ku-Premiere ne-After Effects, ngakho-ke ama-CUDA cores abaluleke kakhulu kimi. I-OpenCL isebenza kahle kakhulu nabashayeli bewebhu be-Nvidia ku-Mac futhi. I-i5 kanye ne-8GB ye-RAM ayifaneleki ikakhulukazi ukuhlelwa, ikakhulukazi ukunikezwa nokubhala ikhodi kuzocasula kakhulu. :D
Angiqondi ukuthi kungani bengathulanga isibonisi se-5K esiqondile, bangahlala besebenzisa iphaneli efanayo :(
I-Apple kuphela engathengisa inkampani yehluzo eneminyaka emibili ubudala. Kuyangidumaza, masingathakathwa isibonisi se-wow 5K. Mhlawumbe kuhle kubalandeli ababukele uchungechunge lwe-TV, kodwa i-HW ayikwazi ukuphatha imuvi, ingasaphathwa eyomdlalo esinqumweni esinjalo. Kuyinhlekisa... Ukucushwa okuhloniphekile kuyenzeka nge-4GB ye-VRAM kanye nephrosesa ye-4GHz kanye no-16GB we-RAM, kodwa lokho cishe kuhumushela ku-70.000 CZK kanye nomsebenzi kanye ne-VAT, ngakho-ke cishe 80.000 lapha futhi ngizoyithenga ngempela leyo urn noma i-Mac. I-Pro cylinder :)
Useduze kwayo. Sawubona
Ngokusobala i-troll, ubhala into efanayo ngaphansi kwesihloko esilandelayo... Ngakho ngingeza impendulo efanayo futhi - i-NVIDIA ingcono kakhulu, kodwa ungakhethi. Okwethulwe yi-Apple ku-iMac wukunikezwa KWAMANGALA kwamakhadi e-ATI angcono kakhulu emakethe. Uma ukhetha i-ATI njengabanye abakhiqizi abaningi, ngeke ukwazi ukunikeza okuthile okungcono.
Kufanele futhi ngengeze ukuthi lona akuwona umshini owenzelwe imidlalo. Awukwazi ukugijima imidlalo yamanje nge-4K, ingasaphathwa eye-5K, kunoma iyiphi ikhompuyutha namuhla. Iyeke kokuthi KONKE-KUNYE, isiqephu sokwahlulela. AKUKHO mshini wamanje wegeyimu okhona futhi ongeke wenzelwe i-4K noma i-5K, ngakho-ke angiboni ukuthi kungani uwusola ku-iMac yangempela, engayifuni ngisho nale ndima. Ikhadi lezithombe likhona kuphela ukuze kusheshiswe ividiyo nokuboniswa kwalo lonke uhlelo ngo-5K. Ukuthi i-ATI noma i-NVIDIA ikhona yini ebaluleke kakhulu kuleli cala kunakwenye indawo, ngoba alikho ithuba lokusebenzisa imidlalo engu-5K nanoma iyiphi inkampani.
Akulona ikhadi elidala lemifanekiso, kodwa bona impendulo yami yokuqala. Uma kungenjalo, angazi ngochungechunge olusakazwa ku-4K/5K, ngifundise. Uma kungenjalo, i-GB RAM ayihlangene nokulungiswa kwesibonisi.
Ngokombono wami, lo mshini wenzelwe ukuzijabulisa kwe-multimedia njengokuphequlula iwebhu, izithombe, amamuvi kanye nomsebenzi uma uhlela amavidiyo futhi ikakhulukazi uhlela izithombe ne-DTP.
KULUNGILE. Ngakho-ke izodalelwani i-iMac 5K, uma kungeyona eyemidlalo? Kuzithombe? Bese ungakwazi ukuqagela mayelana nekhwalithi yesibonisi sale njongo, ukwethembeka kokunikezwa kombala, i-gamut, njll. Ngifaka nje i-plenary ukuthi yini futhi ihloselwe bani i-iMac 5K enjalo? Ehhovisi ku-Word? Ngalolo hlobo lwemali?
Ngokuhlelwa kwevidiyo, amavidiyo ahamba phambili e-4K. Noma ngonjiniyela wokuthuthukisa isoftware.
Uhlela ividiyo ye-4K ngekhadi lezithombe ze-2GB yeminyaka engu-2? Woza …
Imidwebo inobuchwepheshe bakamuva obuvela ku-AMD Mantle, obungekho eminyakeni emibili edlule. Okulandelayo, i-OpenCL inokusekelwa okungcono kune-nVidia, ephusha i-CUDA yayo. Ngeke ngisho ukuthi yikhadi elineminyaka emi-2 ubudala. I-BTW, ngama-euro angu-250, ungakhokha okwengeziwe ukuze uthole enamandla kakhulu nge-4GB ye-RAM.
Kunjalo, ngicaphuna kusixhumanisi http://notebook.cz/clanky/technologie/2014/amd-radeon-r9-m290x-stale-stejny-kral-mobilniho-segmentu-amd: "Isihlalo sobukhosi se-accelerator enamandla kunazo zonke okwamanje siphethwe yi-NVIDIA,
kodwa i-AMD isengaphakathi kwebanga. Hlobo luni lwesikhali oluphezulu kohla lwaso lwamanje, i-R9 M290X?
Kufanele kuqashelwe ukuthi akukho lutho olujabulisayo. Ushintsho olukhulu kakhulu lwezobuchwepheshe olwethulwe yi-AMD kuleli khadi aludingi kuchazwa kabanzi, kuwukuqamba kabusha okulula, okungukuthi ukuqamba kabusha. Inhloso ngokwayo yinhle, ifinyeza igama elithi Radeon kuya ku-R futhi wengeze inombolo ukuze kube lula ukuhlukanisa isigaba sokusebenza (lapha 9 ngochungechunge oluphakeme kakhulu) mi
izosindisa inombolo yezinkinobho futhi abasebenzisi bazothola indlela yabo kumenyu ngokushesha. Uma kuqhathaniswa namakhodi amade amadijithi amane esizukulwane sangaphambilini, lokhu kuyisinyathelo esiya phambili nakanjani. Kodwa i-AMD ihlose ukuzuza egameni elisha ngokushesha, ngakho ngaphansi "kwe-hood" yegama elisha sithola ikhadi elidala le-Radeon HD.
8970M, ngaphandle kwezinguquko.
Futhi ngingaqhubeka nokubalisa. I-Radeon HD 8970M empeleni ayilona ikhadi leselula elihlakaniphile, kodwa indaba yedeskithophu ekhishwe ngoMashi 2012. Ngakho-ke i-AMD iyinkosi yengxenye yeselula iminyaka emibili.
ikhadi ledeskithophu elidala elinamafrikhwensi anqunyiwe kanye nesakhiwo esihlukile sezingxenye ebhodini (ngoba ngamaza aphansi ashisa kancane futhi angasondelana ndawonye). Okuthile akubonakali kahle lapha. Kunohlangothi olulodwa kuphela olukhanyayo kuyo yonke into - okuhlala kufunwa ukusebenza kwedeskithophu kukhompuyutha ephathekayo?
uphumile ngempela..
Ngakho-ke, okokuqala, lelo khadi akulona elemidlalo, noma ngabe imidlalo eguqulelwe ku-Mantle izosebenza kulo ngaphandle kwezinkinga ngisho nakusinqumo se-5K. Okwesibili, isoftware yayo yenziwa i-Apple, futhi i-Apple izoqinisekisa ukuthi konke kuhamba kahle kuyo. I-AMD futhi isebenzisa ihluzo ku-Mac Pro, ngakho-ke ngeke ibe nomsebenzi omningi.
Futhi yilokho ebengikufuna, ukuthi akekho umenzi womprosesa onekhono lokukhulula iphrosesa entsha enesakhiwo esisha njalo ngonyaka. Ngisho ne-Intel ayikwenzi, ngisho ne-nVidia. Isakhiwo esisha sihlala sikhishwa kanye njalo eminyakeni emi-5, futhi ngaphandle kwalokho esamanje sithuthukiswa kuphela, imisebenzi emisha yengezwa, ukusetshenziswa kuyancipha, njll.
Ingabe unikezela ngevidiyo ngekhadi lemifanekiso?
Yini engeke? Uma ishesha kune-CPU :)
Yeka umbhedo, ukwakha umshini wokudlala ukudlala imidlalo yanamuhla ku-4k akuyona inkinga. Ungakwazi futhi ukuthenga eseyakhiwe futhi intengo izocishe ifane naleyo oyikhokhela le imac.
ngempela? ngakho-ke ngicela ungibonise yona, ngifisa ukwazi ukuthi ungangena kanjani ku-$2500, lapho izokubiza kuphela imonitha, uma ufuna ngempela ukuqhathanisa :D
Angibhali ngekhwalithi yemonitha, ngiphendula emazwini akho okuthi "AWUKHO umshini wamanje wegeyimu futhi awukwazi ukwenzelwa i-4K noma i-5K" okungelona iqiniso. Isixhumanisi sokuqala ku-google ngeseHholo 300 Samvidia 4k intengo 85 ayizinkulungwane kuhlanganise qapha. Okungekho kude nentengo ye-iMac (okuthi, njengoba ngifunde ngezansi, ibiza ama-65 eCzech Republic, nokusebenza kwayo kwenye indawo.
ngempela uthatha izwi lami ngakho, kulungile kukhona ikhompyutha evalwe ngokweqile ekwazi ukuphatha EMINYE imidlalo ku-4K ku-30FPS kanjalo nje. Ngo-5K, hhayi ngephutha. Ngokuqondene nalabo abafuna ngempela - ngoba nje banjalo, akusho ukuthi bazokwazi ngempela. Futhi, ngikuthatha ngezwi lakho.
Bengifuna ukusho ukuthi ngeke ngempela uthole i-PC engcono enesibonisi esinjalo. Yilokho kuphela..
Abantu abaningi abaqondi uze uzame ngokwakho. Uma udala ihluzo ezidinga kakhulu ku-hardware, ngincoma ukuthi uma useCzech Republic, uye ku-iStyl futhi uyizame, bazokunikeza isoftware ofuna ukuyizama uma uza nayo. Bese sizozijabulisa. Akumele uqhathanise ukuthi, yithi, i-Pohotoshop isebenza kanjani emhlanganweni onamafasitela kanye nomhlangano one-osx, akunakwenzeka...
Imidwebo ye-Radeon R9 M295X isuka kulo nyaka, ishesha kancane kune-GeForce GTX 980M, okumanje iyikhadi lesithupha elisheshayo emakethe.
Ngempela? Ungakwazi yini ukuxhuma kusixhumanisi lapho i-M295X ishesha kune-GTX980M? Ngabe sengibona yonke indawo ukuthi kuphambene impela.

Ukulungisa: i-iMac 5K ene-4GB VRAM, 16GB RAM kanye nephrosesa engu-4GHz ye-88.190 CZK emangalisayo. Hhayi-ke, ungayithengi :) Ngikhetha kakhulu iMac Pro Hexa Core :)
UDell uzokwethula imonitha engu-5K ngoDisemba, enenani elingu-$3000. I-Apple inekhompyutha enenani lika-$2400….
Lokho kuseyinkunzi. Kuyangimangaza ukuthi abekho onjiniyela lapha osesebenze isikhathi eside e-Apple futhi abacebisi labo makhaza okuthi (njengoba ngifunde lapha) abangakuqondi nhlobo.
Ngikushayela ihlombe, bravo, yilokhu okufanele kubukeke! :)
