Intel pentium J2900: kev ntsuam xyuas, kev txheeb xyuas

Pentium J2900 - ib qho zoo tagnrho processor tov rau compact thiab lub zog-npaum computer systems. Ob leeg rau ruaj ruaj thiab mobile. Nws yog hais txog nws cov kev xaiv thiab possibilities yuav tau los sib tham.

Tso lub nti

Lub pentium intel J2900 yog aimed ntawm ib ya ntawm computer nkag-qib cov kev daws. Yog li ntawd nws boasts high efficiency thiab tus nqi qis. Tsis tas li ntawd, lub nti vim tus tus me me luaj li cas thiab tsawg tshav kub tiam yuav siv tau ntse nyob rau hauv lub ultra tus kheej computers. Nyob rau hauv Feem ntau, qhov no tsis muaj tshwj xeeb uas yuav tsum tau mus rau theem ntawm PC kev ua tau zoo, thiab yuav tsum tau yuav tsum tau zog-npaum cov kua uas yuav haum nyob rau hauv ib tug compact pob, ua ke nrog cov uas tsis muaj nqi yuav ntse siv no semiconductor daws teeb meem.

CPU socket rau cov khoom no

Qhov no silicon nti no yog qhia rau installation nyob rau hauv lub nplos nrog FCBGA1170 npav. Tsuas yog ntawm no, nyob rau hauv sib piv rau lub pa collapsible processor nyob, nyob rau hauv cov ntaub ntawv no, unsolder lub nti ncaj qha rau ntawm lub motherboard. Qhov no pub rau computer manufacturers kom txo tus nqi ntawm nws cov ntau lawm thiab txo tau tus nqi ntawm cov khoom tiav. Tab sis ntawm no yog kho los yog Modernization ntawm cov khoom yuav tsis tau ntsib. Nyob rau hauv cov ntaub ntawv no nws yog yooj yim los mus yuav ib tug tshiab laptop los yog system unit.

Technology raug txheej txheem ntawm lub pob zeb ntais siv lead ua

Pentium J2900 processor yog manufactured raws li cov qauv ntawm ib qho ntawm cov feem ntau nyuaj hauj dab rau hnub tim - 22 nm. Namely nws siv nyob rau hauv cov ntaub ntawv no, tso cai rau lub processor nyob rau tom qab ntawm zoo xws li cov peb-tog cov khoom khav ib tug high degree ntawm lub zog efficiency. Nyob rau hauv tas li ntawd, nws yuav tsum tau muab sau tseg tias code npe ntawm tus ntau lawm technology ntawm semiconductor Cheebtsam - TriGate. Vim peb-dimensional layout tshuam txo loj transistors nyob rau hauv cov ntaub ntawv no, thiab zoo li kev daws teebmeem engineering thiaj li tag nrho cov qhov ntev ntawm lub pob zeb ntais substrate.

cache

Heev coj ncaav subsystem ceev volatile nco nyob rau hauv pentium J2900. Txheej txheem cej luam ntawm cov kev specifications ntawm cov khoom ntawd lub xub ntiag ntawm xwb 2 theem ntawm cache. Rau ib tug tes, tsis muaj theem 3 ceev nco tshuam thiaj li ua tau zoo ntawm cov xam system. Tab sis nyob rau tib lub sij hawm thiaj li qhov loj ntawm lub pob zeb ntais nti thiab thiaj li tshav kub tiam ntawm lub nti. Zuag qhia tag nrho cov thawj theem cache loj nyob rau hauv cov ntaub ntawv no yog 224 KB, thiab lub thib ob - 2 Mb.

RAM hom. Number raws

Pentium J2900 nruab nrog dual kev nco maub los uas aims mus ua hauj lwm nyob rau hauv ua ke nrog nrog lub modules DDR3 txheem. Yog li ntawd, nyob tus yeees ntawm xws li ib tug PC yog zoo dua siv xwb 2 ib daim hlab ntawm RAM thiab li tau txais, albeit me me, tab sis tseem kom nyob rau hauv ceev. Ib zaug ntxiv, li ib txwm, full-hom nco bar tsis tau mus saib raws li ib feem ntawm lub PC. Compact loj motherboard kom txwv, thiab nyob rau hauv cov ntaub ntawv no muaj peev xwm yuav nrhiav tau xwb slots tsim LPDDR3. Hais tias yog, tus RAM siv zog ib daim hlab, uas yog aimed ntawm kev siv cov laptops nyob rau hauv muaj pes tsawg leeg. Qhov siab tshaj plaws loj ntawm lub cim xeeb uas yuav raug hais los ntwm mus rau lub nti yog sib npaug zos rau 8 GB.

TDP

Dhau li ntawm tus plaub computational units ntawm lub semiconductor nti tseem yog kev nco xws li, cov cache nco 2 ntau ntau thiab ib qho integrated graphics tsuj roj. Yog hais tias ib tug zoo sib xws tiav set tau rau ib tug high-kev ua tau zoo processor, nws TDP yog nyob rau hauv ntau ntawm 75 rau 100 watts. Nyob rau hauv cov ntaub ntawv no, lub chaw tsim tshuaj paus tau txiav txim qhov muaj nqis ntawm no parameter ntawm ib theem ntawm 10 watts. Yog li ntawd, nws yog tau txawm mus kaw txawm tias ib tug passive txias system. Qhov siab tshaj plaws kub rau tib lub J2900 yog 105 ⁰ C. Nyob rau hauv kev muaj tiag, cov nti ua hauj lwm nyob rau hauv lub chav 35 mus 65 ⁰ C, nyob ntawm seb nyob rau theem ntawm complexity ntawm lub sij hawm tam sim nyob rau hauv lub ua hauj lwm.

zaus tej zaum

Lub reference moos zaus nyob rau hauv lub Intel pentium J2900 yog 2.4 GHz. Nyob rau hauv no hom, cov CPU ua hauj lwm cov qauv nyob rau hauv cov ntaub ntawv ntawm kev daws teeb meem nrog tsawg demanding paub tab los yog tshwm sim ntawm overheating ntawm cov semiconductor nti. Nyob rau hauv tag nrho cov lwm yam mob, tus nti keyboards rau tawg hom, thiab nws cov zaus yog txiav ntau zog rau 2.6 GHz.

Lub architectural nta ntawm qhov kev daws teeb meem

Number of tshaj x 86 x 64 xam modules nyob rau hauv cov ntaub ntawv no yog plaub. Technology "gipertreyding", uas yog siv nyob rau hauv lub yav dhau los tiam ntawm lub zog-npaum chips los ntawm Intel, yog tsis tuaj kawm ntawv nyob rau hauv cov ntaub ntawv no. Yog li ntawd, tus xov tooj ntawm qhov kev pab cuam ntws sib npaug zos rau cov xov tooj ntawm cov ntaub ntawv ua cores nti - plaub.

Graphics tsuj roj, kev mus rau hauv lub CPU

Pentium J2900 nruab nrog ib tug integrated graphics tsuj roj. Nws lub npe - HD Graphics. Nrog ib tug zoo li lub npe yuav muaj nyob rau hauv lub graphics card thiab CPU dua. Tshwj tias nyob rau hauv cov ntaub ntawv no nws yog ib tug truncated version ntawm nws. Raws li, tsim yog tsawg dua. Moos speeds yog sib npaug zos rau nws 688-896 MHz, thiab tus naj npawb ntawm kev txhawb qhia - 2.

Kev sib piv nrog analogues

Tam sim no Intel camp direct competitors J2900 yog lub eponymous N3XXX CPU lineup, uas nyob rau yuav luag sib npaug rau tus nqi ntawm cov kev muab kev kawm ntau. Yog li ntawd, tus nqi ntawm cov kev daws, uas yog raws li nyob rau hauv lub hero ntawm no los xyuas, tau tsis yeem tshuam. Sib txeeb los ntawm AMD processors ntawm lub nti yog cov A6 tsev neeg Kabini. Yog hais tias ib tug piv theem ntawm tsim tau thiab cov nqi ntawm cov caij nyoog kawg no yog zoo npaum li cas duab ib feem. Raws li ib tug tshwm sim, ntau preferable purchase PCs, uas yog raws li nyob rau hauv kev sib tw kev txiav txim siab los ntawm AMD, piv txwv li, lub A6-5200. Tab sis thaum los txog rau lub fore lub zog efficiency ntawm lub computer system, nws yog preferable twb saib tej daim los ntawm Intel, tshwj xeeb tshaj yog J2900.

Nqe, lub tswv yim ntawm cov kws txawj thiab cov neeg siv kev xyuas

Cov chaw tsim tshuaj paus kwv yees li $ 94 pentium J2900. Xyuas ntawm cov tswv qhia hais tias nws yog tau mus yuav siab tau koom ua ke nyob rau hauv lub hauv paus ntawm xws li ib tug nti rau lub 250-300 ntawm. . E Cov tsuas drawback ntawm xws li ib tug computer system - tsawg ceev. Rau tus so, nws muaj ib tug xov tooj ntawm zoo: high efficiency, tus nqi tsim nyog, ib tug passive txias system (qhov no kuj implies ib yam tsawg kawg nkaus txog qib uas suab nrov thaum lub sij hawm kev lag luam), tej yam me me luaj li cas. Tag nrho cov no nyob rau hauv tus nqi ntawm cov ua rau lub fact tias xws li system blocks tsis yog li ntawd ntau npaum li cas thiab yog tsis tshua muaj pom.

tau

Balanced zog npaum daws yog lub nkag teb chaws theem pentium J2900. Tam sim no nws yog yuav tau ua txawm ntau muaj txiaj ntsim nyob rau hauv lub teeb ntawm lub rov tshwm sim ntawm ib tug tshiab txoj kab ntawm CPUs rau no kev ua lag luam ya nyob rau hauv lub ntsej muag ntawm pentium G3XXX. Yog li ntawd J2900 nqe nqig txawm ntau, thiab lub CPU tau ua ntau mus siv cuag.
