Daniel Hruska Peb tuaj yeem pom thawj zaug Retina zaub ntawm iPhone 4 hauv xyoo 2010. Tom qab ntawd, cov khoom siv siab heev ua rau nws txoj hauv kev rau iPad ntsiav tshuaj thiab tom qab ntawd mus rau MacBook Pro. Niaj hnub no, Apple tau tshaj tawm 27-nti iMac desktop computer rau lub ntiaj teb, muaj cov zaub nrog 5K daws teeb meem.
Yog tias koj xav paub cov lej tseeb, nws yog qhov kev daws teeb meem ntawm 5120 x 2880 pixels, uas ua rau iMac yog tus thawj coj ntawm cov desktops. 14,7 lab pixels - uas yog raws nraim li cas koj yuav pom ntawm 27-nti zaub. Koj tuaj yeem ua si xya Full HD yeeb yaj kiab ib sab lossis hloov kho 4K video thiab tseem muaj ntau qhov chaw ntawm koj lub desktop.
Tag nrho cov vaj huam sib luag muaj 23 txheej uas nyob tsuas yog 1,4 millimeters. Hais txog lub zog, qhov tshiab Retina 5K zaub yog 30% ntau npaum li cov qauv zaub nkag hauv 27-nti iMac. Ib qho LED yog siv rau lub teeb nraub qaum, cov zaub nws tus kheej yog ua los ntawm TFT (thin film transistor) raws li oxide, piv txwv li Oxide TFT.
Txij li thaum Retina 5K zaub muaj 4 npaug ntau pixels dua li cov duab ntawm iMac yav dhau los, nws yog qhov tsim nyog los hloov txoj hauv kev coj. Apple yog li yuav tsum tau tsim nws tus kheej TCON (lub sijhawm tswj hwm). Ua tsaug rau TCON, iMac tshiab tuaj yeem yooj yim lis cov ntaub ntawv kwj nrog kev nce ntawm 40 Gb ib ob.
Ntawm cov npoo, lub iMac tsuas yog 5 millimeters tuab, tab sis tau kawg nws bulges nyob rau hauv nruab nrab kom haum rau tag nrho cov kho vajtse. Cov cuab yeej siv yooj yim ntawm iMac tau txais quad-core Intel Core i5 processor nrog lub moos ceev ntawm 3,4 GHz, rau tus nqi ntxiv Apple yuav muab lub zog ntau dua 4 GHz i7. Ob lub processors muab Turbo Boost 2.0, uas cia li nce kev ua haujlwm thaum twg xav tau.
AMD Radeon R9 M290X nrog 2GB DDR5 lub cim xeeb saib xyuas cov duab ua haujlwm, thiab rau tus nqi ntxiv koj tuaj yeem tau txais AMD Radeon R9 M295X nrog 4GB DDR5 nco. Raws li kev ua haujlwm nco, 8 GB (1600 MHZ, DDR3) yuav muab ua lub hauv paus. Plaub SO-DIMM slots tuaj yeem txuas nrog txog 32GB ntawm lub cim xeeb.
Koj tau txais 1 TB ntawm Fusion Drive cia rau koj cov ntaub ntawv. Koj tuaj yeem teeb tsa mus txog 3TB Fusion Drive, lossis 256GB, 512GB lossis 1TB SSD. Koj yuav tsis pom cov txheej txheem nyuaj hauv iMac nrog 5K Retina zaub, thiab tsis muaj dab tsi ua rau xav tsis thoob.
Thiab tam sim no rau kev sib txuas - 3,5mm jack, 4x USB 3.0, SDXC nco daim npav qhov, 2x Thunderbolt 2, 45x RJ-4.0 rau gigabit ethernet thiab qhov rau Kensington xauv. Los ntawm wireless technologies, lub iMac txhawb Bluetooth 802.11 thiab Wi-Fi XNUMXac.
Qhov ntev ntawm lub computer (H x W x D) yog 51,6 cm x 65 cm x 20,3 cm. Qhov hnyav tom qab ntawd nce mus txog 9,54 kg. Ntxiv nrog rau iMac nws tus kheej, lub pob suav nrog lub zog cable, Magic Mouse thiab wireless keyboard. Nqe pib ntawm Kua khw hauv internet ntawm 69 crowns.
69 :-)
Apple muaj lub laij lej nthuav :D
Koj puas tau txhais hais tias nws xav tias yuav muaj kev lag luam tsis zoo nyob hauv Europe? E.g. qhov yuav tsum tau warranty ob xyoos nce nqi thiab yog li tus nqi. Ntxiv qee qhov kev tiv thaiv kev hloov pauv ntawm tus nqi pauv thiab kev ua phem 21% VAT, thiab 1USD = 1EUR tus nqi twb ua rau muaj kev nkag siab.
Yog tias kuv nco tau raug nyob hauv Asmeskas tus nqi yuav yog kwv yees li 52 CZK.
Cov nqi hauv Teb Chaws Asmeskas ib txwm hais tsis muaj se. Yog li muab USD 2499 los ntawm tus nqi pauv, ntxiv 21% Czech VAT rau qhov tshwm sim, thiab koj nyob ntawm 65. CZK
Yog tias koj yuav hauv Tebchaws Meskas ntawm is taws nem thiab xa mus rau lwm lub tebchaws uas tsis yog lub khw e-khoom nyob hauv, tsis them se. Thiab txhua lub xeev muaj cov se txawv me ntsis, txawm tias ntau tshaj 4-5%, piv rau Czech koom pheej, nws yog lub vaj kaj siab ...
Jirka: Hauv kuv lub tswv yim, koj ib txwm them se ntawm lub xeev uas cov khoom xa tuaj, lossis thaum kuv yuav ib yam dab tsi, nws ib txwm zoo li ntawd, cov se txawv hauv txhua lub xeev. Nyob rau hauv txhua rooj plaub, yog tias koj xav import nws officially (Kuv txhais tau tias nws yog ib qho nyuaj rau khoom lub iMac rau hauv koj tus kheej lub nra ntawm lub dav hlau thiab smuggle nws), ces them tus CZ se thiab nyob rau hauv lub kawg koj yuav muaj nws heev. cov nyiaj zoo sib xws raws li tus nqi Czech tau teev tseg thiab ntxiv rau tsuas yog nrog ib lub xyoo lav.
...max 4-5%? Qhov ntawd yog qhov nyuaj ... tsuas yog google "muag se".
Tej zaum yuav tsis muaj ib qho screen cais. txaj muag :(
Tsis muaj ib yam dab tsi uas tuaj yeem txuas rau nws :-) Thunderbolt 2 tsis tuaj yeem hloov qhov kev daws teeb meem :-) kom txog rau thaum thunderbolt tshiab tuaj yeem ua nws ... tau kawg muaj txoj hauv kev nyob ib puag ncig nws .. nws yuav txaus yog tias cov zaub ntsia zoo li ob qho kev qhia thiab tom qab ntawd thunderbolt yuav 2 tau hloov pauv ... tab sis hmoov tsis zoo ... nws zoo li tias mus txog thaum cov khoom siv tom ntej yuav tuaj yeem ua haujlwm nrog 5K zaub.
Txawm tias thawj thunderbolt ib txwm muaj cov ntaub ntawv txaus txaus, cia nyob ib leeg ob. Kuv xav tias nws tsuas yog hloov tshiab sw, txoj cai?
Cov ntaub ntawv kwj yog ib yam thiab cov teeb liab video yog lwm :-) Thunderbolt 2 tsuas yog xa cov vis dis aus mus txog 4K daws teeb meem rau ib tus saib ...
Nyob rau hauv tas li ntawd, poob siab heev uas lawv tsis tau sau ib tug qauv uas yuav ua tau nws los yog tsis sau lub saib nyob rau hauv 4K xwb.
Muaj ntau txoj kev xaiv ntawm no thiab tsis muaj dab tsi zoo:
- cov zaub cais yuav nyob twj ywm ntawm qhov kev daws teeb meem niaj hnub no
- cais 4K zaub yuav muaj kev daws teeb meem zoo dua li iMac
- cais 5K zaub tsis tuaj yeem txuas nrog Mac Pro thiab Mac Mini tam sim no
Ok, Kuv tsuas yog tus uas pom Intel Core i5 (3,5GHz) thiab 8GB RAM (nquag?) kev teeb tsa ntawm Retina iMac kuj lom zem heev :D Tsis tas li ntawd, hloov mus rau Radeons ib yam li Nvidia qhia GTX 970 thiab GTX 980 - Yeej qhov zoo tshaj plaws daim npav "cov neeg siv khoom" chav kawm ...
Lawv tsis tau ua ntau yam nrog qhov no, tshwj tsis yog rau cov zaub, uas kuv xav tias tsis muaj txiaj ntsig - Kuv tau zaum pem hauv ntej ntawm 27 "iMac min 2010, yog li kuv tuaj yeem txiav txim siab tias qhov pixel ceev txaus. Cov zaub tej zaum yuav zoo rau kev kho 4k video, tab sis qhov seem ntawm cov khoom siv luv luv rau qhov ntawd, thiab yog tias kuv muaj lub koob yees duab 4k, kuv yuav zaum tau Mac Pro tam sim no.
Zoo, yam tsawg kawg nws ntxias kuv kom tsim ib lub Hackintosh: intel Core i7 4790K (Overclocked rau approx. 4,7 GHz), Nvidia GTX 970 SC, 32 GB RAM (2400 MHz), 2 × 512 GB SSD hauv RAID0... Nqe hais txog $2000
Kuv xav tias qhov kev teeb tsa zoo kawg nkaus, Kuv tsuas yog tsis xav siv NVIDIA cov tshiab raws li koj sau..
kuv xav tias nws zoo thiab. Ntawd yog, tshwj tsis yog rau 8 GB ntawm RAM hauv lub hauv paus, thaum Macbook Pro 15 ″ muaj 16.
Lub iMac muaj qhov zoo ntawm kev ua neeg siv hloov tau. Thiab nws yog pheej yig dua los yuav lawv ntawm lub khw tshaj li ntawm Apple :-)
Zoo, qhov ntawd zoo heev. Raws li lawv tau hloov pauv hauv MBP, nws yooj yim nkag mus rau hauv nws thiab nws ua rau kev txiav txim siab, Kuv tau ua nws tus kheej. Tab sis dab tsi ntawm cov neeg ruam yuav dag los ntawm cov zaub vim tias pheej yig dua RAM hauv iMac?
Hauv 27 ″ iMac, lawv hloov ib txwm los ntawm sab nraub qaum. Ua haujlwm rau ob peb feeb. Thiab raws li cov ntaub ntawv ntawm Apple lub vev xaib, kuv yuav hloov zoo li no hauv retina iMac ib yam nkaus.
Raws li dfx sau - USER
Rau kev kho video, Radeons zoo dua Nvidia. Lawv muaj qhov ua tau zoo dua hauv OpenCL, uas yog siv los ntawm FinalCut Pro X.
Kuv hloov kho hauv Premiere thiab After Effects, yog li CUDA cores tseem ceeb dua rau kuv. OpenCL ua haujlwm zoo heev nrog Nvidia lub webdrivers ntawm Mac ib yam nkaus. Lub i5 thiab 8GB ntawm RAM tsis yog tshwj xeeb tshaj yog haum rau kev kho, tshwj xeeb tshaj yog rendering thiab coding yuav ntxhov heev. :D
Kuv tsis nkag siab tias vim li cas lawv tsis qhia txog 5K ncaj qha, lawv tuaj yeem siv tib lub vaj huam sib luag :(
Tsuas yog Apple tuaj yeem muag lub tuam txhab duab kos duab ob xyoos tiag tiag. Kev poob siab rau kuv, cia peb tsis tau enchanted los ntawm wow 5K zaub. Tej zaum zoo rau cov kiv cua saib TV series, tab sis HW nyuam qhuav tuaj yeem ua yeeb yaj kiab, cia nyob ib leeg ntawm qhov kev daws teeb meem. Nws yog kev thuam... Ib qho kev tsim nyog tau txais nrog 4GB ntawm VRAM thiab 4GHz processor ntxiv rau 16GB ntawm RAM, tab sis qhov ntawd kwv yees li 70.000 CZK ntxiv rau lub luag haujlwm thiab VAT, yog li nyob ib ncig ntawm 80.000 ntawm no thiab kuv mam li yuav qhov urn lossis Mac. Pro lub tog raj kheej :)
Koj nyob ib sab ntawm nws. Nyob zoo
Obviously ib tug troll, koj sau tib yam nyob rau hauv lub tom ntej no tsab xov xwm ... Yog li kuv ntxiv tib lo lus teb dua - NVIDIA zoo dua, tab sis tsis txhob lam tau lam ua. Dab tsi Apple tau qhia hauv iMac yog qhov tam sim no muab ntawm ATI daim npav zoo tshaj plaws ntawm kev ua lag luam. Yog tias koj xaiv ATI zoo li ntau lwm cov tuam txhab, koj tsis tuaj yeem muab qhov zoo dua.
Kuv kuj yuav tsum tau ntxiv tias qhov no tsis yog lub tshuab tsim los rau kev ua si. Koj tsis tuaj yeem khiav cov kev ua si tam sim no hauv 4K, cia nyob ib leeg 5K, ntawm txhua lub computer niaj hnub no. Cia nyob ib leeg hauv ALL-IN-ONE, sliver ntawm kev ncaj ncees. Tsis muaj lub tshuab ua si tam sim no thiab tsis tuaj yeem ua rau 4K lossis 5K, yog li kuv tsis pom vim li cas koj liam nws ntawm iMac tiag, uas tsis txawm thov lub luag haujlwm no. Daim npav daim npav tsuas yog muaj rau kev nrawm nrawm thiab tso saib ntawm tag nrho cov kab ke hauv 5K. Txawm hais tias ATI lossis NVIDIA yog qhov tseem ceeb hauv qhov no dua li lwm qhov, vim tias tsis muaj txoj hauv kev los khiav 5K kev ua si nrog ob lub tuam txhab.
Nws tsis yog daim npav qub, tab sis pom kuv thawj cov lus teb. Txwv tsis pub, kuv tsis paub txog cov yeeb yaj kiab tau tshaj tawm hauv 4K / 5K, qhia kuv. Txwv tsis pub, GB RAM tsis muaj dab tsi ua nrog kev daws teeb meem.
Los ntawm kuv qhov kev xav, lub tshuab no tsuas yog tsim los rau kev lom zem ntau yam xws li browsing lub vev xaib, duab, tsos thiab ua haujlwm thaum kho cov yeeb yaj kiab thiab tshwj xeeb tshaj yog kho cov duab thiab DTP.
OK. Yog li dab tsi yuav lub iMac 5K tsim rau, yog tias tsis ua si? Ntawm cov duab? Tom qab ntawd koj tuaj yeem xav txog qhov zoo ntawm cov zaub rau lub hom phiaj no, kev ncaj ncees ntawm cov xim rendering, gamut, thiab lwm yam. Kuv tsuas yog muab tso rau hauv plenary dab tsi thiab leej twg yog iMac 5K npaj rau? Mus rau qhov chaw ua haujlwm ntawm Word? Rau cov nyiaj ntawd?
Rau video editing, qhov zoo tshaj plaws 4K yeeb yaj duab. Los yog rau tus tsim kho software.
Editing 4K video nrog 2-xyoo-laus 2GB graphics card? Los ntawm…
Cov duab muaj cov thev naus laus zis tshiab los ntawm AMD Mantle, uas tsis muaj nyob hauv ob xyoos dhau los. Tom ntej no, OpenCL muaj kev txhawb nqa zoo dua li nVidia, uas thawb nws CUDA. Kuv yuav tsis hais tias nws yog daim npav 2 xyoos. BTW, rau 250 euros, koj tuaj yeem them ntxiv rau qhov muaj zog dua nrog 4GB ntawm RAM.
Yog lawm, kuv hais los ntawm qhov txuas http://notebook.cz/clanky/technologie/2014/amd-radeon-r9-m290x-stale-stejny-kral-mobilniho-segmentu-amd: "Lub zwm txwv ntawm lub zog tshaj plaws cov duab nrawm yog tam sim no tuav los ntawm NVIDIA,
tab sis AMD tseem nyob hauv ntau yam. Hom riam phom twg yog qhov saum toj kawg nkaus ntawm nws qhov tam sim no, R9 M290X?
Nws yuav tsum tau muab sau tseg tias tsis muaj dab tsi yuav zoo siab txog. Qhov kev hloov pauv loj tshaj plaws uas AMD tau qhia hauv daim npav no tsis tas yuav piav qhia ntawm qhov ntev, nws yog qhov yooj yim re-branding, i.e. renaming. Lub hom phiaj nws tus kheej yog qhov zoo, luv luv lo lus Radeon rau R thiab ntxiv tus lej kom nws yooj yim dua rau kev paub qhov txawv ntawm chav kawm (ntawm no 9 rau qhov siab tshaj plaws) mi
nws yuav txuag tau ntau tus keystrokes thiab cov neeg siv yuav pom lawv txoj kev nyob ib ncig ntawm cov ntawv qhia zaub mov sai dua. Piv rau cov lej plaub tus lej ntev ntawm cov tiam dhau los, qhov no yog ib kauj ruam tom ntej. Tab sis AMD npaj kom tau txais txiaj ntsig los ntawm lub npe tshiab tam sim ntawd, yog li nyob rau hauv "hood" ntawm lub npe tshiab peb pom daim npav Radeon HD qub.
8970M, tsis muaj kev hloov pauv.
Thiab kuv tuaj yeem quaj ntxiv. Radeon HD 8970M tiag tiag tsis yog daim npav zoo tshaj plaws ntawm lub xov tooj ntawm tes, tab sis lub desktop yi tso tawm thaum Lub Peb Hlis 2012. Yog li AMD yog tus huab tais ntawm ntu mobile rau ob xyoos.
daim npav qub qub nrog txiav ntau zaus thiab qhov sib txawv ntawm cov khoom sib txawv ntawm lub rooj tsavxwm (vim nrog cov zaus qis dua lawv ua kom sov tsawg dua thiab tuaj yeem nyob ze ua ke). Ib yam dab tsi zoo li tsis zoo nyob ntawm no. Tsuas muaj ib sab ci rau tag nrho cov khoom - ib txwm xav tau kev ua haujlwm desktop hauv lub laptop?
koj tawm los tiag..
Yog li, ua ntej ntawm tag nrho cov, daim npav ntawd tsis yog rau kev ua si, txawm tias kev ua si yoog rau Mantle yuav khiav ntawm nws yam tsis muaj teeb meem txawm tias hauv 5K daws teeb meem. Thiab qhov thib ob, software rau nws yog tsim los ntawm Apple, thiab Apple yuav ua kom txhua yam ua haujlwm zoo ntawm nws. AMD kuj tseem siv cov duab hauv Mac Pro, yog li nws yuav tsis muaj haujlwm ntau.
Thiab qhov ntawd yog qhov kuv xav tau, tsis muaj cov chaw tsim khoom lag luam muaj peev xwm tso tawm cov txheej txheem tshiab nrog cov qauv tshiab txhua xyoo. Tsis txawm Intel ua nws, tsis txawm nVidia. Ib tug tshiab architecture yog ib txwm tso tawm ib zaug txhua 5 xyoos, thiab txwv tsis pub tus tam sim no tsuas yog txhim kho, tshiab zog ntxiv, noj yog txo, thiab lwm yam.
Puas yog koj rendering video nrog ib tug graphics card?
Dab tsi yuav tsis? Thaum nws nrawm dua CPU :)
Dab tsi yog ntuj raug txim, tsim lub tshuab ua si los ua si niaj hnub no hauv 4k tsis yog teeb meem. Koj tseem tuaj yeem yuav ib qho twb tau tsim thiab tus nqi yuav zoo ib yam li qhov koj them rau qhov imac no.
tiag tiag? yog li thov qhia rau kuv paub, kuv xav paub tias koj tuaj yeem ua li cas rau $ 2500, thaum nws tsuas yog tus nqi rau koj saib, yog tias koj xav sib piv :D :D
Kuv tsis tau sau txog qhov zoo ntawm tus saib, kuv tau teb rau koj cov lus hais tias "Tsis muaj lub tshuab ua si tam sim no thiab tsis tuaj yeem ua rau 4K lossis 5K" uas tsis yog qhov tseeb. Thawj qhov txuas hauv google yog rau Hall 300 Samvidia 4k nqe 85 txhiab suav nrog saib. Uas tsuas yog tsis deb ntawm tus nqi ntawm iMac (uas, raws li kuv nyeem hauv qab no, tus nqi 65 hauv Czech koom pheej, thiab nws qhov kev ua tau zoo yog lwm qhov.
koj tsuas yog coj kuv lo lus rau nws xwb, ok muaj lub khoos phis tawj overclocked uas tuaj yeem ua qee yam kev ua si hauv 4K ntawm 30FPS ib yam li ntawd. Hauv 5K, tsis yog yuam kev. Raws li rau cov xav tau tiag tiag - tsuas yog vim lawv yog, tsis tau txhais hais tias lawv yuav ua tau tiag tiag. Ib zaug ntxiv, kuv coj koj ntawm koj lo lus.
Kuv xav hais tias koj yeej yuav tsis pom lub PC zoo dua nrog cov zaub zoo li no. Yog tag nrho..
Ntau tus neeg tsis to taub txog thaum koj sim koj tus kheej. Yog tias koj tsim cov duab uas xav tau ntau dua ntawm cov khoom siv kho vajtse, kuv xav tias thaum koj nyob hauv Czech koom pheej, koj mus rau iStyl thiab sim nws, lawv yuav muab cov software uas koj xav sim yog tias koj nqa nrog koj. Ces peb mam li muaj kev lom zem. Koj yuav tsum tsis txhob sib piv yuav ua li cas, hais, Pohotoshop khiav ntawm lub rooj sib txoos nrog lub qhov rais thiab ntawm lub rooj sib txoos nrog osx, nws tsuas yog ua tsis tau ...
Radeon R9 M295X cov duab yog los ntawm lub xyoo no, me ntsis sai dua GeForce GTX 980M, uas tam sim no yog thib rau daim npav ceev tshaj plaws ntawm kev ua lag luam.
tiag tiag? Koj tuaj yeem txuas mus rau qhov txuas qhov twg M295X nrawm dua GTX980M? Tom qab ntawd kuv pom txhua qhov chaw uas nws yog qhov sib txawv.

Kho: iMac 5K nrog 4GB VRAM, 16GB RAM thiab 4GHz processor rau ib qho zoo kawg 88.190 CZK. Zoo, tsis txhob yuav nws :) Kuv nyiam Mac Pro Hexa Core :)
Dell yuav tshaj tawm 5K saib thaum Lub Kaum Ob Hlis, tus nqi ntawm $ 3000. Apple muaj lub computer nqi ntawm $2400….
Uas tseem bullshit. Kuv xav tsis thoob tias tsis muaj ib tus engineers ntawm no tau ua haujlwm ntawm Apple tau ntev thiab tsis qhia cov neeg limhiam uas (raws li kuv tau nyeem ntawm no) tsis nkag siab txhua..
Kuv npuaj teg, bravo, qhov no yog qhov nws yuav tsum zoo li! :)
