Intel Pentium J2900: Ukubuyekeza, ukubuyekezwa

J2900 Pentium - ikhambi enhle processor I-compact futhi eyongayo zekhompyutha. Bobabili i-umile neselula. Kumayelana ongakhetha yakhe kanye amathuba okuzoxoxwa ngayo.

Positioning chip

I Pentium Inthanethi J2900 kuhloswe ingxenye computer entry level izixazululo. Ngakho-ke inama ukusebenza kahle eliphezulu futhi eziphansi. Futhi, i-chip ngenxa ubukhulu elincane futhi ongaphakeme ukushisa isizukulwane ingasetshenziswa ngempumelelo e amakhompyutha ultra siqu. Ngokuvamile, lapho kungekho izidingo ezikhethekile ezingeni PC ukusebenza, futhi isidingo isisombululo saziso eyonga amandla ukuthi ukwazi ukubona ukuthi ngabe iphakheji compact, kuhambisana nezindlela ongaphakeme kungenziwa ngokuphumelelayo wasebenzisa leli Semiconductor izixazululo.

CPU isokhethi yalo mkhiqizo

Lokhu chip is ngamakhasimende ukufakwa e izisekelo ne FCBGA1170 wokugubha. lapha kuphela, ngokungafani kuya ezivamile egoqekayo processor enethiwekhi, kulesi simo, unsolder chip ngqo umbadlana. Lokhu kuvumela abakhiqizi ikhompyutha ukwehlisa izindleko zokukhiqiza yayo tinhlelo kanye nekunciphisa tindleko umkhiqizo osuphelile. Kodwa nansi bayawukhanda noma sesimanje imishini ayisakwazi wahlangana. Kulokhu kuba lula ukuthenga entsha ephathekayo noma uhlelo iyunithi.

Ubuchwepheshe yokukhiqiza inqubo crystal Silicon

Pentium J2900 processor ekhiqizwa ngokuvumelana nezindinganiso omunye izinqubo eziphambili kakhulu kwezobuchwepheshe kube yimanje - 22 NM. Okungukuthi elisetshenziswa Kulokhu, ivumela processor ku ngemuva imikhiqizo third-party efanayo ngiziqhayise ngezinga eliphezulu ekusetjentisweni kwemandla ngalokuyimphumelelo. Ngaphezu kwalokho, kufanele kuphawulwe ukuthi igama ikhodi ubuchwepheshe ukukhiqizwa izingxenye Semiconductor - TriGate. Ngenxa isakhiwo ngakuthathu kakhulu encishisiwe usayizi transistors kulesi simo, futhi sengathi isixazululo ubunjiniyela kunciphisa Ubukhulu isiyonke substrate silicon.

isilondolozi

Izimo zethu zihluke kakhulu nesizotha subsystem ihlelwe okusheshayo inkumbulo esishubile Pentium J2900. Sibutsetelo ezibekiweko lobuchwepheshe komkhiqizo kubonisa khona 2 kuphela amazinga isilondolozi. Ngakolunye uhlangothi, kungekho ezingeni 3 inkumbulo okusheshayo kakhulu kunciphisa ukusebenza kohlelo Computing. Kodwa ngesikhathi esifanayo kunciphisa ubukhulu chip kanye kunciphisa ukushisa isizukulwane chip. Sekukonke ubukhulu lokuqala isilondolozi ezingeni kulokhu 224 KB, kanti eyesibili - 2 Mb.

RAM izinhlobo. Inombolo iziteshi

Pentium J2900 ifakwe ezimbili okuhlangene inkumbulo isilawuli okuhlose ukusebenza lihambisana indinganiso amamojuli DDR3. Ngakho-ke, ukwakheka PC ezifana kungcono ukusebenzisa 2 nje emapheshana RAM, ngaleyo ndlela athole siqala elincane, kodwa namanje ukwandisa isivinini. Nalapha futhi, evamile, esigcwele format imemori ibha engakutholi ukubona njengengxenye PC. Compact usayizi umbadlana zibeka imingcele, futhi kulesi simo zingatholakala Slots kuphela yakha LPDDR3. Okungukuthi, RAM esetshenzisiwe mfushane emapheshana, okuyinto yenzelwa ukusetshenziswa laptops e kwengoma. Usayizi wokugcina inkumbulo ukuthi zingabhekiswa chip ilingana 8 GB.

TDP

Ngaphandle amayunithi ezine yezamakhompyutha chip Semiconductor futhi ehlangene inkumbulo isilawuli, imemori isilondolozi amazinga 2 kanye oludidiyelwe ihluzo namafutha. Uma isethi ephelele efanayo ubelokhu processor ukusebenza okuphezulu, TDP salo ku uhla kusuka Watts 75 100. Kulokhu, umenzi isinqume ukubaluleka kwalesi ipharamitha ezingeni-10 Watts. Ngakho-ke, kungenzeka ngisho ukuba afinyelele ngisho yokwenziwa Ukupholisa uhlelo. Amazinga esiphezulu ukuze J2900 esifanayo 105 ⁰ C. Empeleni, i-chip usebenza ku ekupha 35 kuya 65 ⁰ C, kuye ngokuthi ezingeni obulukhuni isikhathi samanje umsebenzi.

imvamisa ezingaba

Isethenjwa imvamisa iwashi ku Intel Pentium J2900 kuyinto 2.4 GHz. Kule modi, CPU usebenza imodeli endabeni izixazululo imisebenzi bafune noma okwenziwe okweqile chip Semiconductor. Kuzo zonke ezinye izimo, ukushintshwa chip Burst imodi, futhi imvamisa yayo ngokuzenzakalelayo lande laba ngu-2.6 GHz.

Izici ezakhiwo ukucutshungulwa izixazululo

Inombolo ehambisanayo x86 x64 Computing amamojuli kulokhu ezine. Ubuchwepheshe "gipertreyding", okuyinto waqalwa ngo isizukulwane esedlule sakwa-chips eyonga amandla kusuka Intel, engekho kuleli cala. Ngakho-ke, inani Uhlelo nokusakazwa ilingana nenani information processing cores chip - ezine.

Ihluzo namafutha, bafakwe CPU

Pentium J2900 ifakwe oludidiyelwe ihluzo namafutha. Igama layo - HD Graphics. With igama efanayo ingatholakala ihluzo ikhadi futhi CPU ikhiqize kakhudlwana. Ngaphandle ukuthi kuleli cala luwuhlobo ufushanisiwe ngakho. Ngakho, ukukhiqiza ingaphansi. Clock ngesivinini ayalingana MHz 688-896 yayo, futhi inani ekhombisa asekelwe - 2.

Ukuqhathanisa analogue

Manje ikamu Intel izimbangi oqondile J2900 iyona eponymous N3XXX CPU uhlelo, okuyinto cishe ulingana izindleko zokuhlinzeka ukusebenza ephakeme. Ngakho-ke, izindleko izixazululo, okuncike hero lokhu kubuyekezwa, uye wehlile. Umncintiswano kusuka AMD izilimi chip kukhona A6 umndeni Kabini. Uma izinga efanayo umkhiqizo futhi izindleko yokugcina kungcono kakhulu ingcaca ingxenye. Ngenxa yalokho, akukhetha kakhulu ukuthenga PC, okuncike isinqumo yokuncintisana kusukela AMD, isibonelo, A6-5200. Kodwa lapho kuziwa kuqhame songa amandla uhlelo kukhompyutha, Kungcono kakade bheka chips Intel, ikakhulukazi J2900.

Inani, umbono wezazi kanye nokubuyekeza umsebenzisi

Umenzi kulinganiselwa $ 94 Pentium J2900. Izibuyekezo abanikazi ibonisa ukuthi kungenzeka ukuthenga ababebuthene ngokugcwele ngesisekelo chip ukuthi lezi zinto ziyokwenzeka 250-300 ngesikhathi. . E Okuwukuphela ethile njalo kwesimiso esinjalo ikhompyutha - isivinini esiphansi. Kukho konke, it has eziningi eziwusizo: ukusebenza kahle eliphezulu, ngemali ephansi, i-yokwenziwa Ukupholisa uhlelo (lokhu kusebenza eliphansi umsindo ngesikhatsi operation), usayizi amancane. Konke lokhu inani phambili yokuthi lolo hlelo amabhlogo alikho ngempela futhi lengatfolakali.

Imiphumela

Olinganiselayo eyonga ugesi Isixazululo entry level Pentium J2900. Manje ukuthenga isibe ngisho inzuzo ngaphezulu ukukhanya ukuvela ulayini ebuyekeziwe CPUs kule ingxenye imakethe lapho sibhekene Pentium G3XXX. Ngakho-ke J2900 intengo lehla nakakhulu, futhi CPU isibe kufinyeleleke kalula.
