Intel Pentium J2900: review, reviews

Pentium J2900 - wani manufa processor bayani ga m da kuma makamashi-m kwamfuta tsarin. Duka domin tsit da kuma mobile. Yana game da zabin da yiwuwa za a tattauna.

sakawa guntu

A Pentium Intel J2900 ne da nufin a kashi na kwamfuta shigarwa-matakin mafita. Kamar haka alfahari high dace da low cost. Har ila yau, guntu saboda da gwada da kananan size da kuma zafi kadan tsara za a iya amfani da nasara a cikin matsananci sirri kwakwalwa. A general, inda akwai wani musamman bukatun da matakin na PC yi, da kuma m bukatar makamashi-m bayani da cewa zai iya shige a wani m kunshin, guda biyu tare da low cost za a iya samu nasarar amfani da wannan semiconductor mafita.

CPU soket ga wannan samfurin

Wannan silicon guntu an fuskantar ga shigarwa a cikin soket da FCBGA1170 alama. Kawai a nan, da bambanci ga al'ada collapsible processor kwasfansu, a wannan yanayin, unsolder guntu kai tsaye a kan motherboard. Wannan damar kwamfuta masana'antun zuwa rage kudin da ta samar da rage kudin da ƙãre samfurin. Amma a nan shi ne gyara ko zamanintar da kayan aiki na iya ba a sadu. A wannan yanayin yana da sauki ga saya wani sabon kwamfutar tafi-da-gidanka, ko kuma tsarin naúrar.

Technology masana'antu tsari na silicon crystal

Pentium J2900 processor ne kerarre bisa ga bukatunsu na daya daga cikin mafi m fasaha matakai zuwa kwanan - 22 nm. Wato ta amfani da a wannan yanayin, damar da processor a kan bango na kama ɓangare na uku kayayyakin fariya a babban mataki na samar da makamashi yadda ya dace. Bugu da kari, ya kamata a lura da cewa code sunan samar da fasaha na semiconductor aka gyara - TriGate. Saboda da uku-girma layout ma rage girman transistors a cikin wannan hali, da kuma kamar injiniya bayani rage overall girma na silicon substrate.

cache

Quite suna fadin shirya subsystem sauri maras tabbas memory a Pentium J2900. Overview na fasaha bayani dalla-dalla na samfurin nuna gaban kawai 2 matakan cache. A daya hannun, babu matakin 3 azumi memory ma rage wasan kwaikwayon na sarrafa kwamfuta tsarin. Amma a lokaci guda rage girman da silicon guntu da kuma rage zafin rana ƙarni na guntu. Overall farko matakin cache size a cikin wannan yanayin ne 224 KB, da kuma na biyu - 2 Mb.

RAM iri. Number of tashoshi

Pentium J2900 sanye take da dual Hadakar memory mai kula da nufin yin aiki a hade tare da kayayyaki DDR3 misali. Saboda haka, abun da ke ciki na da irin wannan PC ne mafi alhẽri ga amfani kawai 2 tube na RAM da haka sami, albeit kananan, amma har yanzu kara a gudun. Sa'an nan, ya saba, full-format memory mashaya ba sa ganin matsayin wani ɓangare na PC. Karamin size motherboard kallafa hani, da kuma a cikin wannan yanayin da za a iya samu ne kawai ramummuka samar LPDDR3. Wato, da RAM mori taqaitaccen tube, wanda ake nufin da yin amfani da kwamfyutocin a cikin abun da ke ciki. Matsakaicin size of memory cewa za a iya jawabi ga guntu ne daidai da 8 GB.

TDP

Bayan da hudu mai aiki da na'urar kwamfuta raka'a na semiconductor guntu ne ma Hadakar memory mai kula, da cache memory 2 matakan da wani Hadakar graphics totur. Idan wani m cikakken sa ya kasance a kan wani high-yi processor, ta TDP ne a cikin kewayon daga 75 zuwa 100 watts. A wannan yanayin, da manufacturer ya m darajar wannan siga a matakin 10 watts. Saboda haka, yana yiwuwa ko don tsare ko a m sanyaya tsarin. Matsakaicin yawan zafin jiki ga wannan J2900 ne 105 ⁰ C. A gaskiya, guntu aiki a cikin kewayon 35 zuwa 65 ⁰ C, dangane da matakin da wuya daga cikin halin yanzu lokaci a cikin aikin.

mita m

A reference Agogon mita a cikin Intel Pentium J2900 ne 2.4 GHz. A wannan yanayin, da CPU aiki da model a cikin hali na mafita da kasa bukatn ko da ya faru na zafi fiye da kima daga cikin semiconductor guntu. A duk sauran lokuta, guntu sauya su fashe yanayin, kuma ta mita ne ta atomatik karu zuwa 2.6 GHz.

The gine-gine da fasali na aiki mafita

Number of jituwa x86 x64 sarrafa kwamfuta kayayyaki a cikin wannan yanayin ne hudu. Technology "gipertreyding", wanda aka aiwatar a baya ƙarni na makamashi-m kwakwalwan kwamfuta daga Intel, shi ne ba ya nan a wannan harka. Saboda haka, yawan shirin koguna daidai da adadin bayanai aiki tsakiya guntu - hudu.

Graphics totur, batutuwa a cikin CPU

Pentium J2900 sanye take da wani Hadakar graphics totur. Its sunan - HD Graphics. Tare da irin wannan sunan za a iya samu a cikin graphics katin da CPU mafi m. Sai dai cewa a cikin wannan harka shi ne a truncated version of shi. Haka kuma, yawan aiki ne m. Clock gudu ne daidai ta 688-896 MHz, da kuma yawan goyon nuni - 2.

Kwatanta da analogues

Yanzu Intel sansanin kai tsaye fafatawa a gasa J2900 ne eponymous N3XXX CPU jeri, wanda a kusan daidai da kudin na samar da mafi girma yi. Saboda haka, kudin da mafita, wadda ake bisa gwarzo na wannan nazari, ya ki ma. Gasar daga AMD sarrafawa daga cikin guntu ne A6 iyali Kabini. Idan wani m matakin na yawan aiki da kuma kudin da karshen ne mafi alhẽri mai hoto part. A sakamakon haka, mafi fin so sayan inji mai kwakwalwa, wadda ake bisa m yanke shawara daga AMD, misali, da A6-5200. Amma lokacin da ya zo da fore da makamashi yadda ya dace da kwamfuta tsarin, shi ne fin so zuwa riga duba kwakwalwan kwamfuta daga Intel, musamman J2900.

Price, ra'ayi na masana da kuma mai amfani reviews

A manufacturer kiyasta $ 94 Pentium J2900. Sharhi kan masu nuna cewa, yana yiwuwa ya saya cikakken taru a kan tushen da irin wannan guntu ga 250-300 a. . E The kawai drawback irin wannan kwamfuta tsarin - low gudun. Ga sauran, shi yana da yawan abũbuwan amfãni: high dace, m price, wani m sanyaya tsarin (wannan ma yakan haifar da wani m matakin na amo lokacin aiki), dada size. Duk wannan a cikin adadin gubar da gaskiyar cewa irin wannan tsarin tubalan ne ba sosai, kuma suna da wuya samu.

sakamakon

Daidaita makamashi ingantaccen bayani ne shigarwa matakin Pentium J2900. Yanzu ya buying ya zama ma fi riba a cikin hasken da zargin an sabunta layi na CPUs ga wannan kasuwar kashi a fuskar Pentium G3XXX. Saboda haka J2900 farashin ya ragu ko da more, da CPU ya zama mafi m.
