Sibutsetelo processor yesihlanu Core i7-870: incazelo, izici kanye nokubuyekeza

Iwuhlelo central processing unit "Kor I7 870" kusukela corporation "Intel" akhiqizwa 2009, okuyinto ngisho manje uyakwazi ngaphandle nobunzima ukuxazulula ngisho imisebenzi eyinkimbinkimbi kakhulu ezocatshangelwa imininingwane le nto. Kuzoba futhi anikezwe amandla nobuthakathaka crystal Semiconductor.

Mina wawukwazi le chip? ingxenye emakethe yayo

Isenzo sokunqophisa plan lobuchwepheshe ukuze "Kor I7 870 'siyaqhubeka tisabalulekile nokuxazulula izinkinga ngaphandle kwezinkinga, kuhlanganise eziyinkimbinkimbi kakhulu. Kulokhu, asikho isidingo esithile ukwandisa imvamisa iwashi (ie, "overclock" the chip). ezine ukucutshungulwa yakhe module ekuqaleni sokuqhuba imvamisa iwashi okuqinile kakhulu futhi fast oluyingozi inkumbulo subsystem enhlanganweni yalo akahlukile kusukela izilimi zamanje. Ngenxa yalokho, sithola enye chip ukuyedlula 2009, okuyinto emva kweminyaka 7 kusukela kuqale yokuthengisa siyaqhubeka kube lusizo.

Izinketho CPU

Intel Core I7 870 wadayiswa ezinguqulweni ezimbili ezahlukene ukucushwa. Okuningi lula futhi kufinyeleleke kuwo azibiza ngokuthi "Treil '." Kulokhu, umsebenzisi ithola yokusetshenziswa kanye lewaranti, umkhiqizo ilebula umndeni ka Semiconductor chips futhi chip uqobo. Eyesibili inketho ukucushwa ngokuthi "Ibhokisi", futhi kwaba inguqulo Boxed the ephakathi processing unit. Kuhlanganisa, ngaphezu izingxenye ezishiwo ngaphambilini ukuba isihumusho ukumisa, njengoba cooler isitokwe, ibhokisi uphawu nokunamathisela ezishisayo.

Ukulungiselelwa okufana lokuqala ezifaneleke kangcono kwikhompyutha abathanda kanye overclockers, abakwazi ukukhokhela ukuthenga indlu uhlelo eziphambili futhi ngaleyo ndlela andise ukusebenza sokugcina uhlelo kukhompyutha. Kodwa inguqulo Boxed ukucushwa kangcono abasebenzisi abavamile, futhi lapho ukusebenza eyisisekelo yaleli neqhinga ngempela ngokwanele.

isokhethi

Intel Core I7 870 iye igxile ukufakwa eziphambili kakhulu izisekelo 2009 Nhlangano "Intel" yekhompyutha entry level izixazululo - LGA1156. Futhi kwaba omunye izilimi kahle kakhulu endaweni yesikhulumi. Isethi eziyisisekelo logic kulokhu lalinabashumayeli eyodwa kuphela Southbridge - P55. A bridge enyakatho washukumiseleka ukuba umzimba chip. Kamuva ngabo, kunezinye chipsets lunga yesikhulumi - N57 Express ne H55 Express. Empeleni, kwaba okufanayo njengoba P55, kodwa kwalokho ihluzo subsystem. Ngokufanele ngokuhlanganyela CPU iye yasetshenziswa kuba P55, okuyinto kwaba ngempela ngokwanele amathuba ekusabalaliseni ephezulu ukusebenza Semiconductor izixazululo.

inqubo

Core I7 ukucutshungulwa emaphakathi iyunithi 870 yenziwa ngokuvumelana nemithetho inqubo (45 NM), eyayise-2009 godu isihambile. It kudlule iminyaka engu-7 futhi inqubo eside (14 NM) lisetshenziswe ukukhiqizwa kumakhompyutha izixazululo eziphambili. Naphezu umehluko omkhulu kangaka, lokhu chip ephezulu ukusebenza uyaqhubeka kube lusizo futhi ngaphandle kwezinkinga ungakwazi ukuxazulula noma yiziphi izinkinga ngisho nanamuhla.

isilondolozi

CPU High Core I7 870 kufanele ifakwe ezintathu-level isilondolozi Kuphoqelekile. Ukube kwakungenjalo, kwakuyomelwe ngeke bakwazi ukuxazulula eyinkimbinkimbi anda inkinga, ngisho 2009. Kulokhu, amandla isitoreji kufanele futhi ube usayizi ezinhle.

Ngenxa yalokho, design onjiniyela baye wahlomisa it kanje:

• Izinga lokuqala core ngasinye owasithumela yizinqamu 2 amamojuli 32 kb. Omunye wabo ezikhethekile isitoreji imiyalelo CPU, kanti eyesibili - ku isitoreji kwemininingwane. Lokho, umuntu angase ayisebenzisele module yezamakhompyutha 64 kb isiyonke. Hhayi-ke, njengoba inani eliphelele cores ilingana 4, bese sithola 4 * 64 = 256 kbps.

• Izinga lesibili engakakhuli lunye enjalo okuqinile uhlobo ulwazi olugcinwe, kodwa lalihlukene phakathi izikhwebu ngabanye. Likhono Computing ngamunye iyunithi ilingana 256kb. Well, isamba lingakanani inani 1 MB (4 kuya 256 kb nucleus).

• Esesithathu isilondolozi ezingeni kuvamile kubo bonke CPUs. Ubukhulu bayo ilingana 8 MB.

Okungahleliwe-ukufinyelela inkumbulo

I7 CPU 870 iye igxile ukusetshenziswa eziphambili kakhulu ngaleso sikhathi ezifana uHlelo Lwesiqondisi Kungena Esilula - "DDR3". umakhi yena watusa izikhwebu nalokhu ukusetshenziswa kwe-CPU "DDR3-1066" emapheshana noma "DDR3-1333". Ngo umkhuba, kwakungenzeka yini ukuba afake ngaphezulu ngesivinini RAM amamojuli yalolu hlobo, kodwa ngeke ikwazi ukusebenza ngokushesha "DDR3-1333". Inani eliphelele RAM, lapho processor zingalungiswa kulokhu-16 GB.

Enye ehilelekile ezibalulekile zobuchwepheshe - ukuhlanganiswa ezimbili-isiteshi inkumbulo isilawuli kuya Semiconductor chip CPU. Le isixazululo ubunjiniyela ikhuphuke kakhulu ukusebenza lokugcina uhlelo kukhompyutha.

Amazinga okusebenza chip Semiconductor. TDP

Umkhawulo lokushisa kuvunyelwe for the "Kor I7 870" zazilingana 72,7 degrees. Ngokuvamile, umkhuba, lokhu kwasho ukuthi uhlelo ukupholisa nganoma yisiphi isizathu uphumile emgqeni. Kwimodi yokusebenza ejwayelekile, izinga lokushisa kwe-chip ungaphakathi uhla 40-55 degrees. Uma overclock lokhu processor iwuhlelo ke ushintsho lokushisa umbuso. Kulesi simo, kuyoba njalo the uhla kusuka degree angu-50 kuya ku-60. Ukuze unqobe ukubaluleka ufanekisela degrees 60 kungenziwa kuphela ukusebenzisa isofthiwe olindele kunazo. Kodwa ngisho esimweni esinjalo, izinga lokushisa neze uya ngalé kwemingcele kuvunyelwe angadluli degrees 70. Shisisa iphakethe lokhu chip zazilingana Watts 95.

imvamisa ifomula

Lokhu chip kwaba ifakwe ubuchwepheshe ezifana "Turbo Boost". Ngakho-ke, iwashi layo imvamisa washintsha kuncike yinkimbinkimbi inkinga ingaxazululeki, inani asebenzayo ukucutshungulwa izinsiza kanye isimo ezishisayo we-CPU. Isethenjwa imvamisa iwashi at ephakeme ukushabalalisa ukushisa e Core I7 870 - 2,93 GHz. Landela ukubaluleka kwakhe - 3.2 GHz.

Kulokhu, kanye wonke amamojuli 4 kuwo womabili izindlela. Kuphela esimweni sokuqala kukhona ukwehla ngenxa okweqile chip, noma ngenxa inkimbinkimbi inkinga, kanti eyesibili - kuzo zonke ezinye izimo lapho udinga ukuya kwesokudla 4 cores. Inani elilandelayo - 3,47 GHz. Ngo kwathatha kule modi esikhathini processor iyanqamula 2-Computing amamojuli. imvamisa Maximum kulokhu 3.6 GHz. Uhlelo kukhompyutha usebenza ngentambo 1 kuphela.

izakhiwo

Igama ikhodi amayunithi yezamakhompyutha chip - Nehalem. Lokhu CPU kuhlanganisiwe ngokushesha 4 i-nucleus. Ngaphezu kwalokho, isici esasenza i-semiconductor okwenza uchungechunge "Kor Ay7" ukusekela ubuchwepheshe nokuphathelene, ikhodi-okuthiwa "Hyper Trayding", okuvumela ngesisekelo core eyodwa ngokomzimba ukuze uthole 2 logic (ie, ezingeni Uhlelo). Lokhu chip Semiconductor kulokhu kwaba okufanayo. Ngenxa yalokho, ezingeni isofthiwe lalibonisa 8 imicu ngokushesha wekhompyutha.

Konke lokhu kuvumela naye ngisho manje, ngaphandle nobunzima kakhulu yokubhekana ngokuphumelelayo nanoma ibuphi isofthiwe isicelo (kokubili elungiselelwe multi-threaded hardware, noma cha).

ukusheshisa

Okwazekayo, kwakunokwenzeka ukuba afeze ezinye usebenzisa Intel I7 870. System ibhasi Overclocking Kodwa practice nomkhiqizi le njongo Kunconywa ukusetshenziswa uchungechunge chips "Kor Ay7 9xx", okuyinto futhi kwadingeka isiqalo "Black Edishon".

Endabeni "Kor Ay7 8xx" ukusebenza ezingeni kwaba ekuqaleni ngokweqile, futhi udale abalulekile umthwalo ezengeziwe ohlelweni computer kwaba okusesilinganisweni kubi. Manje ukusebenza CPU kungahlolwa njengoba anele. It ikuvumela ukusebenzisa noma iyiphi isofthiwe, okuyinto okwamanje.

Umsebenzisi ukubuyekezwa. CPU izindleko

I ethile kuphela, okungaba wokugaya level premium - lena zibiza. Intengo abakhiqizi Kunconywa zazilingana $ 305. Kodwa kumelwe siyaqonda ukuthi into qualitative ayikwazi kubiza ngisho nesenti. Ngakho kuleli cala - chip-to-date ngaphezu konyaka owodwa, kumele kube ezibizayo. Kukho konke, kule CPU kunezinzuzo kuphela. Lezi zihlanganisa ukusebenza, izimo ezishisayo futhi ukusebenza.

Ngisho esincane Intel imvamisa I7 870 2 93 GHz evumela ukusetshenziswa iningi isofthiwe ekhona. Nokho, cishe imodi ngesivinini esikhulu, futhi asikhulumi - bona eminye kwandiswe umkhiqizo.

Imiphumela

Amapharamitha Technical "Kor I7 870" namanje uqhubeke kube lusizo namuhla. Angaqondakali ukuthenga iyunithi uhlelo akuyona (kukhona izixazululo ezintsha inzuzo ngaphezulu). Kodwa nansi ukuthuthukiswa kwe-PC, zingenzeki kakhulu. izinsiza sawo inqobo uma ngokwanele ukuze kuqaliswe ukusebenza cishe noma yimuphi umsebenzi.
