Daniel Hruska Titha kuwona koyamba chiwonetsero cha Retina pa iPhone 4 mu 2010. Pambuyo pake, mawonekedwe apamwamba kwambiri adapita kumapiritsi a iPad kenako ku MacBook Pro. Masiku ano, Apple idabweretsa kompyuta yapakompyuta ya 27-inchi iMac padziko lonse lapansi, yokhala ndi chiwonetsero chapamwamba cha 5K.
Ngati mukufuna kudziwa manambala enieni, ndikusintha kwa 5120 x 2880 pixels, zomwe zimapangitsa iMac kukhala mtsogoleri wathunthu pakati pa desktop. Ma pixel 14,7 miliyoni - ndiwo angati omwe mungapeze pachiwonetsero cha 27-inch. Mutha kusewera makanema asanu ndi awiri a Full HD mbali ndi mbali kapena kusintha kanema wa 4K ndikukhalabe ndi malo ambiri pakompyuta yanu.
Gulu lonse lili ndi zigawo 23 zomwe zimakhala ndi mamilimita 1,4 okha. Pankhani ya mphamvu, chiwonetsero chatsopano cha Retina 5K ndichabwino kwambiri 30% kuposa mawonekedwe omwe amaperekedwa mu 27-inch iMac. LED imagwiritsidwa ntchito powunikira kumbuyo, chiwonetserocho chimapangidwa ndi TFT (thin film transistor) yochokera ku oxide, i.e. Oxide TFT.
Popeza chiwonetsero cha Retina 5K chili ndi ma pixel ochulukirapo 4 kuposa ma iMac am'mbuyomu, kunali kofunikira kusintha njira yolondolera. Chifukwa chake Apple idayenera kupanga yake TCON (yowongolera nthawi). Chifukwa cha TCON, iMac yatsopano imatha kugwira ntchito mosavuta ndi mayendedwe a 40 Gb pamphindikati.
M'mphepete, iMac ndi 5 millimeters wandiweyani, koma ndithudi imatuluka pakati kuti igwirizane ndi zida zonse. Zida zoyambira za iMac zidalandira purosesa ya quad-core Intel Core i5 yokhala ndi liwiro la wotchi ya 3,4 GHz, pamtengo wowonjezera Apple ipereka 4 GHz i7 yamphamvu kwambiri. Mapurosesa onsewa amapereka Turbo Boost 2.0, yomwe imawonjezera magwiridwe antchito pakafunika.
AMD Radeon R9 M290X yokhala ndi kukumbukira kwa 2GB DDR5 imasamalira magwiridwe antchito, ndipo pamtengo wowonjezera mutha kupeza AMD Radeon R9 M295X yokhala ndi kukumbukira kwa 4GB DDR5. Ponena za kukumbukira kogwiritsa ntchito, 8 GB (1600 MHZ, DDR3) idzaperekedwa ngati maziko. Mipata inayi ya SO-DIMM imatha kuyikidwa mpaka 32GB ya kukumbukira.
Mumapeza 1 TB ya malo osungira a Fusion Drive pa data yanu. Mutha kukonza mpaka 3TB Fusion Drive, kapena 256GB, 512GB kapena 1TB SSD. Simupeza ma hard drive mu iMac yokhala ndi chiwonetsero cha 5K Retina, ndipo sizodabwitsa nkomwe.
Ndipo tsopano pakulumikizana - 3,5mm jack, 4x USB 3.0, SDXC memory card slot, 2x Thunderbolt 2, 45x RJ-4.0 ya gigabit ethernet ndi slot ya Kensington loko. Kuchokera ku matekinoloje opanda zingwe, iMac imathandizira Bluetooth 802.11 ndi Wi-Fi XNUMXac.
Makulidwe a kompyuta (H x W x D) ndi 51,6 cm x 65 cm x 20,3 cm. Kulemera kwake kumafika ma kilogalamu 9,54. Kuphatikiza pa iMac yokha, phukusili limaphatikizapo chingwe chamagetsi, Magic Mouse ndi kiyibodi yopanda zingwe. Mtengo umayamba pa Apple Online Store pa korona 69.
69 :-)
Apple ili ndi chowerengera chosangalatsa: D
Kodi mukutanthauza kuti amayembekeza kuti kukhale koipitsitsa kwa bizinesi ku Europe? Mwachitsanzo kuvomerezedwa zaka ziwiri chitsimikizo kumawonjezera ndalama motero mtengo. Onjezani chitetezo pakusintha kwamitengo ndi VAT wankhanza 21%, ndipo mtengo wa 1USD=1EUR ndiwomveka kale.
Ngati ndikukumbukira bwino ku USA mtengo udzakhala pafupifupi 52 CZK.
Mitengo ya US nthawi zonse imatchulidwa popanda msonkho. Chifukwa chake chulukitsani USD 2499 ndikusinthana, onjezani 21% VAT ya Czech ku zotsatira zake, ndipo muli pa 65. CZK
Ngati mumagula ku US kudzera pa intaneti ndikutumiza kudziko lina osati komwe kuli shopu ya e-sitolo, msonkho sulipidwa. Ndipo dziko lililonse lili ndi msonkho wosiyana pang'ono, ngakhale mpaka 4-5%, poyerekeza ndi Czech Republic, ndi paradiso ...
Jirka: Malingaliro anga, nthawi zonse mumalipira msonkho wa boma kumene katundu amaperekedwa, kapena ngati nditagula chinachake, nthawi zonse zimakhala choncho, msonkho ndi wosiyana m'mayiko onse. Mulimonsemo, ngati mungafune kuyitanitsa movomerezeka (ndikutanthauza kuti ndizovuta kuyika iMac m'chikwama chanu pandege ndikubisala), ndiye perekani msonkho wa CZ ndipo pomaliza mudzakhala nawo. ndalama zofanana kwambiri monga mtengo wa Czech wotchulidwa, komanso, ndi chitsimikizo cha chaka chimodzi chokha.
…kuposa 4-5%? Izi mwina ndizovuta ... basi google "msonkho wogulitsa".
Mwina sipadzakhala chiwonetsero chapadera panobe. Manyazi :(
Palibe chomwe chingalumikizidwe kwa icho :-) Bingu la 2 silingathe kusamutsa chigamulo chotere :-) mpaka bingu latsopano lingathe kuchita ... ndithudi pali njira yozungulira .. monga zowonetsera ziwiri ndiyeno bingu 2 akanatha kusamutsa ... koma mwatsoka ... zikuwoneka kuti mpaka zipangizo zotsatirazi zitha kugwira ntchito ndi chiwonetsero cha 5K
Ngakhale bingu loyamba nthawi zonse limakhala ndi deta yokwanira, osasiya ziwiri. Ndikuganiza kuti ndikusintha kwa sw, sichoncho?
Kuthamanga kwa data ndi chinthu chimodzi ndipo chizindikiro cha kanema ndi china :-) Thunderbolt 2 imatha kutumiza kanema mpaka ku 4K kuwunikira kumodzi ...
Zikatero, anakhumudwa kwambiri kuti sanatchule mulingo womwe ungathe kuugwira kapena sanalembe zowunikira mu 4K m'malo mwake.
Pali zosankha zingapo pano ndipo palibe chabwino:
- chiwonetsero chapadera chikhalabe pamalingaliro amasiku ano
- chowonetsera chapadera cha 4K chidzakhala ndi chisankho chabwino kuposa iMac
- mawonekedwe osiyana a 5K sangathe kulumikizidwa ndi Mac Pro ndi Mac Mini
Chabwino, ndi ine ndekha amene ndimapeza kasinthidwe ka Intel Core i5 (3,5GHz) ndi 8GB RAM (kawirikawiri?) Retina iMac moseketsa kwambiri kwenikweni makadi abwino kwambiri "ogula" kalasi ...
Sanachite zambiri ndi izi, kupatula chiwonetsero, chomwe ndimachiwona chopanda ntchito - ndikukhala kutsogolo kwa 27 ″ iMac min 2010, kotero nditha kuweruza kuti kuchuluka kwa pixel ndikokwanira. Kuwonetsera kungakhale kwakukulu pakusintha kanema wa 4k, koma zida zina zonse ndizofupikitsa, ndipo ngati ndili ndi kamera ya 4k, ndipeza Mac ovomereza pofika pano.
Chabwino, osachepera zinandikhutiritsa kupanga Hackintosh: Intel Core i7 4790K (Overclocked to approx. 4,7 GHz), Nvidia GTX 970 SC, 32 GB RAM (2400 MHz), 2 × 512 GB SSD mu RAID0 ... Mtengo wa $2000
Ndikuganiza kuti kasinthidwe kalikonse, sindikufuna kugwiritsa ntchito NVIDIA yatsopano pamene mukulemba.
Zikuwoneka bwino kwa inenso. Ndiye, kupatula 8 GB ya RAM m'munsi, pamene Macbook Pro 15 ″ ili ndi 16.
IMac ili ndi mwayi wokhala wosinthika. Ndipo ndizotsika mtengo kwambiri kuzigula pamsika kuposa za Apple :-)
Chabwino, izo ndi zabwino kwenikweni. Monga iwo anali osinthika mu MBP, zinali zosavuta kulowamo ndipo zinali zomveka, ndinazichita ndekha. Koma ndi chitsiru chamtundu wanji chomwe chingagone pawonetsero chifukwa cha RAM yotsika mtengo mu iMac?
Mu 27 ″ iMac, amasintha bwino kuchokera kumbuyo. Gwirani ntchito kwa mphindi zingapo. Ndipo malinga ndi zomwe zili patsamba la Apple, ndisintha motere mu retina iMac.
Monga dfx akuti - USER
Pakusintha kwamavidiyo, ma Radeons ndiabwino kuposa Nvidia. Amachita bwino kwambiri mu OpenCL, yomwe imagwiritsidwa ntchito ndi FinalCut Pro X.
Ndimasintha mu Premiere ndi After Effects, kotero CUDA cores ndizofunikira kwambiri kwa ine. OpenCL imagwiranso ntchito bwino ndi mawebusayiti a Nvidia pa Mac. I5 ndi 8GB ya RAM sizoyenera kusinthidwa, makamaka kupereka ndi kukopera kudzakhala kokhumudwitsa. :D
Sindikumvetsa chifukwa chake sanawonetse chiwonetsero chowongoka cha 5K, amatha kugwiritsa ntchito gulu lomwelo nthawi zonse :(
Ndi Apple yokha yomwe ingagulitsedi kampani yazaka ziwiri yojambula zithunzi. Zokhumudwitsa kwa ine, tisakodwe ndi chiwonetsero cha wow 5K. Mwina zabwino kwa mafani omwe amawonera makanema apa TV, koma HW sangathe kuthana ndi kanema, osasiya masewera oterowo. Ndizoseketsa... Kukonzekera koyenera ndi kotheka ndi 4GB ya VRAM ndi purosesa ya 4GHz kuphatikiza 16GB ya RAM, koma izi zimatanthawuza 70.000 CZK kuphatikiza ntchito ndi VAT, kotero pafupifupi 80.000 pano ndipo ndiguladi urn kapena Mac. Pro cylinder :)
Inu muli pafupi ndi izo. Moni
Mwachiwonekere troll, mumalemba zomwezo pansi pa nkhani yotsatira ... Kotero ndikuwonjezera yankho lomwelo kachiwiri - NVIDIA ndi yabwino kwambiri, koma musakhale ndi tsankho. Zomwe Apple idayambitsa mu iMac ndi CURRENT kuperekedwa kwamakhadi abwino kwambiri a ATI pamsika. Ngati mungasankhe ATI monga opanga ena ambiri, simungapereke chilichonse chabwinoko.
Ndiyeneranso kuwonjezera kuti iyi si makina opangira masewera. Simungathe kuyendetsa masewera amakono mu 4K, osasiya 5K, pakompyuta iliyonse lero. Siyani mu ZONSE-M'MODZI, chidutswa cha chiweruzo. PALIBE makina amasewera omwe alipo ndipo sangapangidwe a 4K kapena 5K, chifukwa chake sindikuwona chifukwa chake mumayimba mlandu pa iMac yeniyeni, yomwe sichimadzitengera gawo ili. Khadi lojambula lilipo kuti lipititse patsogolo makanema ndikuwonetsa dongosolo lonse mu 5K. Kaya ATI kapena NVIDIA ilipo ndiyofunikira kwambiri pankhaniyi kuposa kwina kulikonse, chifukwa palibe mwayi wothamanga masewera a 5K ndi kampani iliyonse.
Si khadi lachikale lojambula, koma onani yankho langa loyamba. Kupanda kutero, sindikudziwa za mndandanda womwe ukufalitsidwa mu 4K/5K, ndiphunzitseni. Kupanda kutero, GB RAM ilibe chochita ndi mawonekedwe owonetsera.
Kuchokera kumalingaliro anga, makinawa amapangidwa makamaka kuti azisangalala ndi ma multimedia monga kusakatula intaneti, zithunzi, makanema ndi ntchito pokonza makanema komanso makamaka kusintha zithunzi ndi DTP.
CHABWINO. Ndiye iMac 5K idzapangidwira chiyani, ngati simasewera? Pa zithunzi? Ndiye mutha kulingalira za mtundu wa chiwonetserochi pachifukwa ichi, kukhulupirika kwa kumasulira kwamitundu, gamut, ndi zina zambiri. Ku ofesi pa Mawu? Ndalama zamtundu umenewo?
Pakusintha makanema, makanema abwino kwambiri a 4K. Kapena kwa wopanga mapulogalamu.
Mukusintha kanema wa 4K ndi khadi yazithunzi ya 2GB yazaka ziwiri? Inu …
Zojambulazo zili ndi ukadaulo waposachedwa kwambiri kuchokera ku AMD Mantle, womwe kulibe zaka ziwiri zapitazo. Chotsatira, OpenCL ili ndi chithandizo chabwinoko kuposa nVidia, yomwe imakankhira CUDA yake. Sindinganene kuti ndi khadi lazaka ziwiri. BTW, kwa 2 euros, mutha kulipira zowonjezera kuti mukhale ndi mphamvu zambiri ndi 250GB ya RAM.
Ndiko kulondola, ndikunena za ulalo http://notebook.cz/clanky/technologie/2014/amd-radeon-r9-m290x-stale-stejny-kral-mobilniho-segmentu-amd: "Mpando wachifumu wamagetsi amphamvu kwambiri othamangitsa zithunzi ukusungidwa ndi NVIDIA,
koma AMD idakali mkati. Ndi chida chotani chomwe chili pamwamba pamtundu wake wapano, R9 M290X?
Kuyenera kudziŵika kuti palibe chosangalatsa. Kusintha kwakukulu kwaukadaulo komwe AMD idayambitsa mu khadi ili sikuyenera kufotokozedwa motalika, ndikuyikanso chizindikiro chosavuta, mwachitsanzo. Cholinga chokha ndi chabwino, kufupikitsa mawu akuti Radeon kukhala R ndikuwonjezera nambala kuti zikhale zosavuta kusiyanitsa gulu lamasewera (pano 9 pamndandanda wapamwamba kwambiri) mi
idzapulumutsa makiyi angapo ndipo ogwiritsa ntchito adzapeza njira yawo mozungulira menyu mwachangu. Poyerekeza ndi manambala aatali anayi am'badwo wakale, ichi ndi sitepe yakutsogolo. Koma AMD ikufuna kupindula ndi dzina latsopano nthawi yomweyo, kotero pansi pa "hood" ya dzina latsopano timapeza khadi lakale la Radeon HD.
8970M, popanda kusintha konse.
Ndipo ndikhoza kupitiriza kulira. Radeon HD 8970M kwenikweni si khadi yanzeru yam'manja, koma nkhani yapakompyuta yomwe idatulutsidwa mu Marichi 2012. Chifukwa chake AMD ndi mfumu ya gawo la mafoni kwa zaka ziwiri.
makadi akale apakompyuta okhala ndi ma frequency odulidwa komanso mawonekedwe osiyana a zigawo pa bolodi (chifukwa ndi ma frequency otsika amawotcha pang'ono ndipo amatha kuyandikirana). Chinachake sichikuwoneka bwino apa. Pali mbali imodzi yokha yowala pa chinthu chonsecho - nthawi zonse mumafuna magwiridwe antchito apakompyuta pa laputopu?
mwachokadi..
Chifukwa chake, choyambirira, khadiyo simasewera, ngakhale masewera omwe adasinthidwa kukhala Mantle amayendetsa popanda zovuta ngakhale pakusankha kwa 5K. Ndipo chachiwiri, mapulogalamu ake amapangidwa ndi Apple, ndipo Apple adzaonetsetsa kuti zonse zikuyenda bwino. AMD imagwiritsanso ntchito zithunzi mu Mac Pro, kotero sizikhala ndi ntchito zambiri.
Ndipo ndizomwe ndimafuna, kuti palibe wopanga purosesa yemwe angathe kumasula purosesa yatsopano yokhala ndi zomangamanga zatsopano chaka chilichonse. Ngakhale Intel samachita, ngakhale nVidia. Zomangamanga zatsopano zimatulutsidwa kamodzi pazaka 5 zilizonse, ndipo apo ayi zomwe zilipo zimangosinthidwa, ntchito zatsopano zimawonjezeredwa, kugwiritsa ntchito kumachepetsedwa, ndi zina zambiri.
Kodi mukupereka vidiyoyi ndi khadi lazithunzi?
Kodi sichikanatero? Pamene ili mofulumira kuposa CPU :)
Zopanda pake, kumanga makina amasewera kuti azisewera masewera amasiku ano mu 4k si vuto. Mutha kugulanso yomwe idamangidwa kale ndipo mtengo wake udzakhala wofanana ndi zomwe mumalipira imac iyi.
zoona? kotero chonde ndiwonetseni, ndikufuna kudziwa momwe mungakwaniritsire $2500, pomwe zingakuwonongerani chowunikira, ngati mukufuna kufananiza :D
Sindikulemba za mtundu wa polojekiti, ndikuyankha mawu anu kuti "PALIBE makina amasewera omwe alipo ndipo sangapangidwe 4K kapena 5K" zomwe sizowona. Ulalo woyamba pa google ndi wa Hall 300 Samvidia 4k mtengo 85 zikwi kuphatikiza polojekiti. Zomwe sizili kutali ndi mtengo wa iMac (yomwe, monga ndidawerengera pansipa, imawononga 65 ku Czech Republic, ndipo magwiridwe ake ali kwina.
mukungotengera mawu anga, chabwino pali kompyuta yodzaza kwambiri yomwe imatha kuchita masewera ENA mu 4K pa 30FPS monga choncho. Mu 5K, osati molakwitsa. Ponena za omwe akufunadi - chifukwa chakuti ali, sizikutanthauza kuti adzachita bwino. Apanso, ndikutengera mawu ako.
Ndinkafuna kunena kuti simupeza PC yabwino yokhala ndi chiwonetsero chotere. Ndizomwezo..
Anthu ambiri samamvetsetsa mpaka mutayesa nokha. Ngati mupanga zithunzi zomwe zimakhala zovuta kwambiri pa hardware, ndikupangira kuti mukakhala ku Czech Republic, mupite ku iStyl ndikuyesa, adzakupatsani pulogalamu yomwe mukufuna kuyesa ngati mutabwera nayo. Ndiye tidzasangalala. Simuyenera kuyerekeza momwe, titi, Pohotoshop imayendera pagulu lomwe lili ndi mazenera komanso pagulu la osx, sizingatheke ...
Zithunzi za Radeon R9 M295X zachokera chaka chino, zothamanga pang'ono kuposa GeForce GTX 980M, yomwe pakali pano ndi khadi lachisanu ndi chimodzi lachangu pamsika.
Zoona? Kodi mungalumikizane ndi ulalo womwe M295X ili mwachangu kuposa GTX980M? Kenako ndinaona paliponse kuti zinali zosiyana ndendende.

Kukonza: iMac 5K yokhala ndi 4GB VRAM, 16GB RAM ndi purosesa ya 4GHz ya 88.190 CZK yodabwitsa. Chabwino, musagule :) Ndimakonda Mac Pro Hexa Core :)
Dell adzakhazikitsa polojekiti ya 5K mu Disembala, yamtengo wa $3000. Apple ili ndi kompyuta yamtengo wa $2400….
Izo zikadali zopusa. Ndine wodabwa kuti palibe mainjiniya pano omwe akhala akugwira ntchito ku Apple kwa nthawi yayitali ndipo sakulangiza amatsenga omwe (monga momwe ndikuwerengera apa) sakumvetsetsa konse.
Ndikuthokoza, bravo, izi ndi momwe ziyenera kuwoneka! :)
