Intel Pentium J2900: ukuhlaziywa, ukuhlolwa

I-Pentium J2900 iyona isisombululo esifanelekileyo seprojekthi yeekhompyutheni zeekhompyutheni kunye ne-energy-efficient. Kwaye zombini isistim kunye neselula. Kuye malunga neerameters zayo kunye nezixhobo eziza kuxutyushwa ngazo.

Ukubeka i-chip

I-Intel Pentium J2900 ijoliswe kwicandelo lokusombulula iikhomputha zekhompyutha. Ngexesha elifanayo, linomlinganiselo ophezulu wokusebenza kwamandla kunye neendleko eziphantsi. Kwakhona, ngenxa yobukhulu bayo obukhulu kunye nokushisa okuphantsi kweqondo, le chip ingasetyenziswa ngempumelelo kwiikhompyutheni ze-ultracompact. Ngokuqhelekileyo, apho kungekho mfuno ezizodwa kwizinga le-PC ukusebenza, kwaye nakanjani isisombululo esiphezulu samandla esifanelekileyo singakwazi ukulungelelanisa kwiipakethe ezihambelanayo, kunye neendleko eziphantsi, isisombululo se-semiconductor singasetyenziswa ngempumelelo.

Isitoreli salo mveliso weprojekthi

Le cristal i-crystal ixhomekeke ekufakwe kwisiseko kunye nokumakisha FCBGA1170. Kuphela apha, ngokuchasene nezixhumo eziqhelekileyo ezixhasayo zeprojekithi, kule ngxaki i-chip idibanisa ngqo kwi-motherboard. Oku kuvumela abenzi beekhompyutha ukuba bahlise iindleko zemveliso yabo kwaye banciphise indleko zeemveliso ezigqityiweyo. Kodwa ukulungiswa okanye ukuhlaziywa kwezixhobo ezinjalo akunakuzaliseka. Kule meko, kulula ukuthenga i-laptop okanye i-unit unit.

Ubuchwephesha kwinkqubo yokuvelisa i-crystal

Iprojector ye-Pentium J2900 yenziwe ngokuhambelana nemimiselo yenkqubo enye yezobuchwepheshe obuphambili kakhulu ukuya kutsho - 22 nm. Kusetyenziswa kwakhe kule meko evumela ukuba iprojector iqhayise umlinganiselo ophezulu wokusebenza kwamandla ngokumalunga nemvelaphi yeemveliso ezifanayo zenkampani yesithathu. Ukongeza kule nto, kufuneka kuqatshelwe ukuba igama lekhowudi ye-teknoloji yokuveliswa kwezinto ze-semiconductor yi-TriGate. Ngenxa yokucwangciswa kwamathathu, ubukhulu bezithuthi ziyancitshiswa kakhulu kule meko, kwaye esi siphumo sobunjineli sinciphisa ubungakanani bomhlaba we-silicon substrate.

Cache

Issystem of memory memorium fast in Pentium J2900 ihlelwe ngokuthobeka. Ukuphononongwa kweenkcukacha zobugcisa bale mveliso kubonisa ukuba khona kwamanqanaba amabini kuphela. Ngakolunye uhlangothi, ukungabikho kwinqanaba le-3 lokukhumbuza ngokukhawuleza kunciphisa kakhulu isivinini sekhompyutha. Kodwa ngexesha elifanayo, ubukhulu be-crystal cristal buyancipha kwaye ukukhululwa kwe-chip chip kuyancipha. Ubungakanani bebonke becache yokuqala kwinqanaba kule dilesi ngu-224 KB, kunye neyesibini-2 MB.

Iindidi ze-RAM. Inani leziteshi

I-Pentium J2900 ixhotywe ngomlawuli womemori womgca we-channel, ejoliswe ekusebenzeni ngokudibanisa needyuli zeDDR3 eziqhelekileyo. Ngoko ke, ekubunjweni kwe-PC enjalo kulungele ukusebenzisa i-RAM ye-2 ye-RAM ngokukhawuleza kwaye, ngenxa yoko, ufumane, nokuba uncinci, kodwa kusekhona inzuzo yokusebenza. Kwakhona, iziqhelo eziqhelekileyo eziqhelekileyo ze-RAM azikwazi kubonakala kwi-PC. Ubungakanani bekhampani zamabhinqa bubeka imingcipheko, kwaye kulo mzekelo unokuhlangabezana kuphela nemida yelo hlobo LPDDR3. Oko kukuthi, iisetyenzisiwe ze-RAM zenziwe zifutshane, ezijoliswe ekusebenziseni kwii-laptops. Isixa esiphezulu seR RAM esi sidilesi sinokubamba i-8 GB.

Iphakheji yomoya

Ukongeza kwiiyunithi ezine zekhompyutha kwi-chip semiconductor, kukho kwakhona umlawuli wokukhumbula imemori, imemori yokugcina umgca wamanqanaba amabini kunye ne-accelerator ehlanganisiweyo. Ukuba izixhobo ezifanayo zikwinkqubo ephezulu yokusebenza, i-packet yayo yokufudumala yayiya kubanzi ukusuka kwi-75 ukuya ku-100 W. Kwimeko efanayo, umenzi wenza ixabiso le parameter kwizinga le-10 W. Ngako oko, unako ukukhawuleza kwimeko yokupholisa. Ubume obukhulu be-J2900 ngu-105 ⁰ C. Ngokwenene, le chip isebenza kwi-35 ukuya kwi-65 ⁰ C, kuxhomekeke kwinqanaba lezinto eziyinkimbinkimbi yomsebenzi wangoku.

Ukuphindaphinda

I- speed reference clock kwi- Intel Pentium J2900 yi-2.4 GHz. Kule ndlela, le mzekelo ye-CPU isebenza kwimeko yokuxazulula iingxaki ezingabonakaliyo okanye xa i-crystal semiconductor ishushu. Kuzo zonke ezinye iimeko, i-chip iyatshintsha kwimodi ye-Burst, kwaye i-frequency yayo ngokuzenzekelayo iyanda kwi-2.6 GHz.

Iimpawu zokwakha zomsebenzi wesisombululo

Inombolo yee-modules ezihambelana ne-x86-x64 kule meko zine. I-teknoloji ethi "HyperTrading", eyaphunyezwa kwisizukulwana esidlulileyo se-chips esebenzayo yamandla esuka kwi-Intel, ayikho kulo mzekelo. Ngako ke, inani le-software yolwazi lokucwangciswa kolwazi lilingana nenani lee-computing cores ze-chip-ezine.

I-accelerator ye-Graphical edibeneyo kwi-CPU

I-Pentium J2900 ifakwe i-graphics accelerator edibeneyo. Igama layo yi-HD Graphics. Ngegama elifanayo, umntu unokufumana kwakhona ikhadi levidiyo kwiCCU ezisebenzayo. Kuphela apha kweli gama sithetha ngenguqu elandelwayo. Ngoko ke, izinga lokusebenza linciphile. Amaxesha ayo amaxesha anama-688-896 MHz, kunye nenani leemiboniso ezixhaswayo ngu-2.

Ukuthelekisa kunye neempawu

Ngoku kwenkampu ye-Intel, ukukhuphisana ngokuthe ngqo kwe-J2900 yi-CPU ezifanayo ezibizwa ngokuba yi-N3XXX, elineendleko ezilinganayo, ezinikezela ngokukhawuleza ukusebenza. Ngoko ke, iindleko zezisombululo, ezisekelwe kwiqhawe le ngongoma, liye lahla kakhulu. Kwiphepha le-AMD, abakhuphiswano beli chip baprojekthi ze-A6 zentsapho yaseKabini. Ngezinga elilinganayo lentsebenzo kunye neendleko, lo mva unesabelo esilungileyo. Ngenxa yoko, ukuthengwa kwee-PC ngokusekelwe kwisisombululo esikhuphisanayo ukusuka kwi-AMD, umzekelo, i-A6-5200, iyona ekhethekileyo. Kodwa ukuba ukusetyenziswa kwamandla kwenkqubo yekhompyutheni kuza kuqala, ke i-Intel chips, ingakumbi i-J2900, ikhethwa ngakumbi.

Ixabiso, uluvo lweengcali kunye nokuhlaziywa kwabasebenzisi

Ngama-dollar angama-94 aqikelelwa ngumenzi wePentium J2900. Izimvo zabanini zibonisa ukuba kunokwenzeka ukuba kuthenge ukuhlanganiswa ngokupheleleyo ngokusekelwe kweso sididi ukuya kuma-250-300 y. E. Impendulo yodwa yenkqubo yekhompyutheni isantya esiphantsi. Ngaphandle koko, unamathuba amaninzi: ukusetyenziswa kwamandla aphezulu, iindleko ezifikelelekayo, inkqubo yokupholisa (oku kuthetha ukuba ubuncinane bezinga lentsimbi ngexesha lokusebenza), ubukhulu becala. Zonke ezi zizonke zikhokelela ekwenzeni ukuba iibhloko ezithintelayo azinqabile.

Iziphumo

Isisombululo esinokulinganisela kwamandla okungena kumgangatho wePentium J2900. Ngoku ukuthengwa kwayo kuye kwaba nenzuzo ngakumbi ekukhanyeni kokubonakala komgca ohlaziyiweyo weprojekthi zecandelo le marike kumntu wePentium G3XXX. Ngoko ke, iindleko ze-J2900 ziye zancipha kwakhona, kwaye le CPU ifikeleleke ngakumbi.
