Intel Pentium J2900: review, ndemanga

Pentium J2900 - yabwino purosesa njira kachitidwe yaying'ono ndi mphamvu imayenera kompyuta. Onse n'kupuma ndi mafoni. Ndi za chithandizo ndi mwayi ayankhidwa.

kuika Chip ndi

The Pentium Intel J2900 umalimbana ndi gawo njira kompyuta kulowa-mlingo. Choncho lili Mwachangu mkulu ndi mtengo wotsika. Komanso Chip chifukwa kukula ochepa ndi kutentha m'badwo otsika zikhoza kugwiritsidwa ntchito mu kompyuta kopitilira muyeso munthu. Ambiri, komwe kulibe amafuna wapadera kwa mlingo wa ntchito PC, ndi kuvomerezedwa kufunika mphamvu imayenera njira kuti kulumikiza mu phukusi yaying'ono, pamodzi ndi mtengo wotsika akhoza bwinobwino ntchito michenga yopangira zida zamagetsi ili njira.

CPU zitsulo za malonda

Chip Izi pakachitsulo ndi zochokera kwa unsembe mu zitsulo ndi FCBGA1170 ankachita. Only pano, mosiyana ndi ochiritsira mwake collapsible purosesa, mu nkhani iyi, unsolder Chip mwachindunji pa mavabodi lapansi. Zimenezi zimathandiza opanga kompyuta kuti kuchepetsa ndalama yopanga ake ndi kuchepetsa ndalama za chotsirizidwa. Koma apa ndi kukonza kapena wamakono wa zida sangapezekenso anakumana. Pankhaniyi n'kosavuta kugula latsopano laputopu kapena kachitidwe unit.

Technology kupanga ndondomeko ya galasi pakachitsulo

Pentium J2900 purosesa amapangidwa molingana ndi miyezo ya m'modzi wa zapamwamba kwambiri njira zamakono chibwenzi - 22 nm. Ndicho ntchito mu nkhani iyi, akulola purosesa pa maziko a mankhwala ofanana lachitatu chipani kudzitama digiri yapamwamba ya mphamvu Mwachangu. Komanso tisaiwale kuti malamulo dzina la sayansi yopanga zigawo michenga yopangira zida zamagetsi - TriGate. Chifukwa kamangidwe atatu azithunzi omwe tikunena zayamba yafupika kukula transistors mu nkhani iyi, ndi ngati zomangamanga njira amachepetsa miyeso yaikulu ya gawo lapansi pakachitsulo.

posungira

Ndithu wodzichepetsa bungwe subsystem mwamsanga oyaka kukumbukira mu Pentium J2900. Mwachidule specifications ndi luso la mankhwala akusonyeza pamaso pa milingo 2 yekha wa posungira. Pa dzanja lina, palibe mulingo 3 kudya kukumbukira zayamba amachepetsa ntchito za dongosolo kompyuta. Koma nthawi yomweyo amachepetsa kukula kwa Chip pakachitsulo ndipo kumachepetsa kutentha m'badwo wa Chip lapansi. Cacikulu woyamba mlingo posungira kukula mu nkhani iyi ndi 224 KB, ndipo chachiwiri - 2 MB.

RAM mitundu. Chiwerengero cha njira

Pentium J2900 okonzeka ndi wapawiri Integrated kukumbukira Mtsogoleri zomwe cholinga chake ndi ntchito osakaniza ndi zigawo DDR3 muyezo. Choncho, zikuchokera chotero PC bwino ntchito n'kupanga 2 chabe RAM kuti alandire, ngakhale ang'ono, koma kuwonjezera liwiro. Kachiwiri, mwachizolowezi, zonse mtundu kukumbukira bala sakhala ndi kuwona mbali ya PC. Yaying'ono kukula mavabodi amalowerera ufulu ndi Pankhaniyi angapezeke mipata yekha kupanga LPDDR3. Ndi, RAM ntchito adzafupikitsidwa n'kupanga, amene umalimbana ntchito Malaputopu mu zikuchokera. Kukula pazipita kukumbukira kuti angalunjikitsidwe kwa Chip ndi wofanana 8 GB.

TDP

Kuwonjezera pa anayi mayunitsi zowerengera wa Chip michenga yopangira zida zamagetsi ndi Integrated kukumbukira Mtsogoleri, ndi posungira kukumbukira 2 misinkhu ndi Integrated zithunzi accelerator. Ngati ofanana lonse wakhala pa purosesa mkulu-ntchito, TDP ake ali mu osiyanasiyana kuchokera Watts 75 100. Pankhaniyi, Mlengi watsimikiza mtengo wa chizindikiro ichi pa mlingo wa 10 Watts. Choncho n'zotheka ngakhale kuti akunjate ngakhale dongosolo chabe kuzirala. Kutentha pazipita kwa J2900 yemweyo ndiye 105 ⁰ C. Kunena zoona, Chip umagwira ntchito mu osiyanasiyana 35 65 ⁰ C, malingana ndi msinkhu wa kuchulukitsa kwa nthawi ziliri pa ntchitoyo.

kuthekera pafupipafupi

Kutchulidwa wotchi pafupipafupi mu Intel Pentium J2900 ndi 2.4 GHz. Mu mode izi, CPU ukugwira ntchito chitsanzo pa nkhani ya njira ndi ntchito oumirira kapena zosayembekezereka wa kutenthedwa wa Chip michenga yopangira zida zamagetsi. Nthawi zina zonse, masiwichi Chip anayamba mode, ndi pafupipafupi yake basi kuchuluka kwa 2.6 GHz.

Maonekedwe a kamangidwe ka njira ya processing

Chiwerengero cha n'zogwirizana x86 x64 zigawo kompyuta mu nkhani iyi ndi anayi. Technology "gipertreyding", umene akuyendera mbadwo wakale tchipisi mphamvu imayenera ku Intel, palibe nkhaniyi. Choncho, chiwerengero cha pulogalamu mitsinje ofanana kuchuluka kwa mfundo processing mitima Chip - anayi.

Zithunzi accelerator, Integrated mu CPU ndi

Pentium J2900 okonzeka ndi Integrated zithunzi accelerator. Dzinali - HD Zojambula. Ndi dzina ofanana angapezeke mu khadi zithunzi ndi CPU waphindu. Kupatula kuti mu nkhani iyi ndi Baibulo truncated za izo. Choncho, zokolola n'chozama. Clock imathamanga ali wofanana 688-896 MHz ake, ndipo chiwerengero cha kusonyezedwa amapereka - 2.

Kuyerekezera ndi analogues

Tsopano Intel msasa mpikisano mwachindunji J2900 ndi eponymous N3XXX CPU masanjidwe, omwe pafupifupi wofanana ndi mtengo wa kupereka ntchito zapamwamba. Choncho, mtengo njira, zomwe ndi zochokera ngwazi za takambiranazi, wathetsedwa zayamba. Yophuka AMD mapurosesa wa Chip ndiwo A6 banja Kabini. Ngati mlingo china zokolola ndi mtengo wa yamasika bwino likutipatsa gawo. Chifukwa cha zimenezi, kwambiri poyerekeza kugula ma PC, zomwe ndi zochokera chisankho mpikisano ku AMD, mwachitsanzo, A6-5200. Koma pamene zifika Amaonetsa dzuwa mphamvu ya dongosolo computer, ndi bwino kale kuyang'ana tchipisi ku Intel, makamaka J2900.

Price, maganizo a akatswiri ndemanga wosuta

Mlengi pafupifupi $ 94 Pentium J2900. Reviews eni amasonyeza kuti n'zotheka kugula kwathunthu anasonkhana pa maziko a Chip amenewo kwa 250-300 pa. . E The drawback yekha zoterozo dongosolo kompyuta - otsika liwiro. Enawo, izo angapo ubwino: mkulu dzuwa, mtengo wololera, dongosolo chabe kuzirala (ichi zimasonyezanso mlingo osachepera phokoso pa ntchito), kakang'ono kukula. Zonsezi kuchuluka kwa kutsogolera chakuti amenewa dongosolo midadada si kwambiri ndipo kawirikawiri sapezeka.

zotsatira

Kusamala magetsi njira kulowa mlingo Pentium J2900. Tsopano iye kugula wakhala kwambiri opindulitsa mu kuwala kwa zikamera cha mzere kusinthidwa wa CPUs kwa gawo lino msika mu nkhope ya Pentium G3XXX. Choncho J2900 mtengo waponya kwambiri, ndi CPU wakhala mosavuta.
