Amagqabantshintshi iprosesa Intel Core i7-870: inkcazelo, iimpawu kunye nohlolo

unit flagship yokusebenza engundoqo "Kor i7 870" ukusuka corporation "Intel" eveliswa ngo-2009, nto leyo ngoku iyakwazi ngaphandle kobunzima ukucombulula nkqu imisebenzi kakhulu olunzima ziya kuqwalaselwa ngokweenkcukacha kulo mbandela. Kuya kunikwa amandla kunye nobuthathaka, ngathi ngembonakalo yikristale semiconductor.

I wawukwazi chip? ingxenye yayo market

Le iinkcukacha kwesicwangciso bobugcisa ukuze "Kor i7 870" kuqhubeka cwaka ezifanelekileyo nokusombulula iingxaki ngaphandle naziphi na iingxaki, kubandakanywa kakhulu entsonkothileyo. Kulo mzekelo, akukho mfuneko ethile ukwandisa amaza iwashi yayo (oko kukuthi, "overclock" i-chip). umnqongo lakhe processing ezine ekuqaleni ukusebenza rhoqo iwashi kwimemori esezantsi eqinileyo kakhulu ngok ezililize kwintlangano yayo ayahlukanga ukusuka Processors yangoku. Ngenxa yoko, sifumana elinye chip aveza imveliso-2009, emva kweminyaka 7 ukususela ekuqaleni intengiso iyaqhubeka ukuba ufanelekile.

Iinketho CPU

i7 Intel Core 870 yathengiswa kwiinguqulelo ezahlukeneyo ezimbini uqwalaselo. Ngakumbi lula yaye zifikeleleke kubo okhethiweyo njenge "Treil '." Kulo mzekelo, umsebenzisi ifumana imiyalelo ukusetyenziswa kunye nekhadi iwaranti, brand ileyibhile kusapho chips semiconductor kunye chip ngokwayo. Uqwalaselo ukhetho yesibini ekuthiwa "Box", yaye yaba inguqulelo yokulumkisa ye iyunithi yokusebenza engundoqo. Oku kuquka, ukongeza kumacandelo ekhankanywe ngaphambili ukuba inguquko yangaphambili uqwalaselo, njengoko kupholile kwemfuyo, ibhokisi uphawu paste thermal.

Uqwalaselo lobeko yokuqala oluhambelana ngakumbi abathanda khompyutha kunye overclockers, ngaba ngubani ukuthenga i-injini phambili kwaye kwandisa intsebenzo lokugqibela kwenkqubo yekhompyutha. Kodwa version yokulumkisa loqwalaselo ifanele kubasebenzisi eziqhelekileyo, yaye apho yokusebenza engundoqo yolu neqhinga kakhulu ngokwaneleyo.

socket

Intel Core i7 870 kuye kwanikelwa ingqalelo ukufakelwa kakhulu obubalaseleyo okusikrotyana 2009 ombutho "Intel" isicombululo entry-level yekhompyutha - LGA1156. Ke kaloku, omnye iziqhubekisi isebenzayo eqongeni. Iseti basic ekuqiqeni kulo mzekelo yayiquka omnye kuphela Southbridge - P55. A ibhulorho lasentla wafuduselwa umzimba chip. Ekuhambeni kwexesha, kukho ezinye chipsets kweli qonga - N57 Express kunye H55 Express. Enyanisweni, kwaba ngokufanayo P55, kodwa kongezwe esezantsi yemizobo. Ngokupheleleyo ngokudibene CPU iye yasetyenziswa yi P55, nto leyo kakhulu ngokwaneleyo lamathuba lokunabisa le oluphezulu lwe izisombululo semiconductor.

inkqubo

iyunithi yokusebenza i7 engundoqo Core 870 yenziwe ngokungqinelana nemigaqo nkqubo (45 NM), eyayise-2009 godu phambili. Kuye kudlule iminyaka 7 kunye nenkqubo elide (14 NM) ezisetyenziswa kwimveliso izisombululo becomputing phambili. Nangona umahluko omkhulu onjalo, chip eliphezulu-nokwenziwa ukuba efanelekileyo kwaye kungekho naziphi na iingxaki ukusombulula nayiphi na ingxaki nanamhlanje.

cache

CPU High Core i7 870 mayixhotyiswe kwinqanaba ezintathu-cache inyanzelekile. Kungenjalo, akayi kuba nako ukusombulula yobumbaxa ukwanda le ngxaki, nkqu ngo-2009. Kulo mzekelo, amandla yokugcina kufuneka kwakhona ibe ubukhulu elungileyo.

Ngenxa yoko, iinjineli uyilo baxhobise oko ngolu hlobo lulandelayo:

• Inqanaba lokuqala ezingundoqo nganye sithunyelwe yahlulwe 2 iinxalenye iimodyuli 32 KB. Omnye wabo ezizodwa ukugcina imiyalelo CPU, kwaye eyesibini - on nokugcinwa kwedatha. Oko kukuthi, umntu asebenzise umnqongo azo 64 KB ewonke. Kaloku, ekubeni inani elipheleleyo umphakathi ilingana no-4, ngoko ke ufumana 4 * 64 = 256 kbps.

• Inqanaba lesibini akukhange kube ezikhethiweyo ongqongqo kangako kuhlobo iinkcukacha ezikuso, kodwa yohlulwa phakathi kernels ngamnye. Umthamo yeyunithi computing nganye ilingana 256kb. Kaloku, isiphumo yobukhulu balo iyonke yi-1 MB (4 ukuya 256 KB nucleus).

• Inqanaba Cache wesithathu kuqhelekile kubantu bonke CPUs. Ubukhulu balo babulingana-8 MB.

imemori oluzenzekelayo-ufikelelo

I7 CPU 870 kuye kwanikelwa ingqalelo nokusetyenziswa kakhulu ngelo xesha efana imemori yofikelelo oluzenzekelayo - "DDR3". umenzi ngokwakhe abuyise izikhwebu ne nale ukusetyenziswa CPU "DDR3-1066" oonotsheluza okanye "DDR3-1333". Ukuziqhelisa, kwaba lula ukubeka eqinqiweyo isantya RAM hlobo, kodwa abazange babe nako ukusebenza ngokukhawuleza "DDR3-1333". Imali ubuninzi RAM, apho kumqhubekekisi ingabhekiswa kule meko 16 GB.

Enye ezincinane zeteknoloji ebalulekileyo - ukuhlanganiswa memory isilawuli-mbini channel ukuya semiconductor chip CPU. Le isisombululo engineering liye landa kakhulu ukusebenza kwenkqubo yekhompyutha lokugqibela.

Iqondo lobushushu yokusebenza chip semiconductor. TDP

Iqondo eliphezulu ngokuvunywe ukuba "Kor i7 870" wayelingana degrees 72,7. Ngokuqhelekileyo, xa kusenziwa, oku kwakuthetha ukuba inkqubo sokupholisa ngenxa yaso nasiphi na isizathu ngaphandle umyalelo. Kwindlela yokusebenza eqhelekileyo, iqondo lobushushu chip na kuluhlu degrees 40-55. Ukuba overclock le njengomqhubekisi flagship, ngoko utshintsho lobushushu umbuso. Kule meko, kuya kuba kuluhlu ukusuka izidanga-50 ukuya kwama-60. Ukoyisa ixabiso yokomfuziselo degrees 60 kuphela run software eyona inzima. Kodwa kwimeko enjalo, iqondo lobushushu ngenkankulu iya ngaphaya kwemida obuvunyiweyo hayi ngaphezulu degrees 70. Fudumeza iphakheji yale chip wayelingana 95 watts.

frequency ifomula

Le chip yafakwa neteknoloji ezifana "Turbo Boost". Ngoko ke, rhoqo yayo ikloko kwatshintsha kuxhomekeke kubunzima ingxaki ukuba isonjululwe, inani izibonelelo zokwenza esebenzayo kunye nemeko wobushushu of the CPU. I-reference clock Ukuxhaphaka kwi ephakamileyo ukusasaza ubushushu i7 Core 870 - 2,93 GHz. Landela ixabiso lakhe - 3.2 GHz.

Kulo mzekelo, kanye yonke 4 iminqongo asebenze both sides. Kuphela kwimeko yokuqala kukho ukuhla ngenxa nobushushu chip, okanye ngenxa lula le ngxaki, kwaye eyesibini - kuzo zonke ezinye iimeko apho ufuna ukuya umphakathi 4 ngasekunene. Ixabiso elandelayo - 3,47 GHz. Xa uqeqeshelwa ukuba eli imo kwi kumqhubekekisi disconnects iimodyuli-2-computing. frequency eliphezulu kule meko 3.6 GHz. Inkqubo yekhompyutha isebenza ngomsonto 1 kuphela.

bokwakha

Igama code of kwiiyunithi azo chip - Nehalem. Le CPU yayiquka nangoko 4 ngumongo. Ukongeza, isici esasenza lo semiconductor ukwenza uthotho "Kor Ay7" kukuba ukuxhasa nobuchwepheshe obuphuma, ikhowudi-ogama "Hyper Trayding", evumela ngokusekelwe ezingundoqo mnye ukufumana 2 logic (oko kukuthi, kwinqanaba nkqubo). Le chip semiconductor kulo mzekelo, wayexakekile. Ngenxa yoko, kwinqanaba software ngayo yabonisa 8 imisonto nangoko computing.

Konke oku kuvumela kuye ngoku, ngaphandle kobunzima kakhulu ukumelana nayo nayiphi na isicelo software (zombini olulungiselelwe multi-azinamsonto hardware, okanye hayi).

lunikezelo

Ngethiyori, kwaba kungenzeka ukuba afeze ethile usebenzisa Intel i7 870. System ibhasi overclocking Kodwa practice eyakha le njongo ekucetyiswa ukusetyenziswa uthotho chips 'Kor Ay7 9xx ", nayo leyo waba isimaphambili" Black Edishon ".

Kwimeko inqanaba lokwenziwa "Kor Ay7 8xx" ukuba ekuqaleni ngokugqithiseleyo, kunye nokudala umthwalo ezibalulekileyo ezongezelelweyo kwinkqubo yekhompyutha yaba ezingafanelekanga ngokupheleleyo. Ke kaloku ukusebenza CPU nga azivavanywa zanele. It ikuvumela ukuba usebenzise nayiphi na isoftware, apho ngelo xesha.

ncomo umsebenzisi. iindleko CPU

Le ethile kuphela, nto leyo ibe kumqhubekekisi zenqanaba imali - oku iindleko eziphezulu. ixabiso ekucetyiswa lomenzi wayelingana $ 305. Kodwa kufuneka siqonde ukuba into qualitative akakwazi kubiza idenariyo. Ngoko kulo mzekelo - sinochuku-to-umhla ngaphezu konyaka omnye, kufuneka imali eninzi. Elokugqiba, kule CPU zinezibonelelo kuphela. Ezi ziquka umsebenzi, iimeko thermal kunye nokusebenza.

Nkqu ubuncinane Intel frequency i7 870 2 93 GHz ivumela ukusetyenziswa ezininzi software ekhoyo. Kaloku, malunga indlela-high speed, yaye bethetha nathi - ukuba ngakumbi ukwandisa imveliso.

iziphumo

Technical iparameters "Kor i7 870" basaqhubekeka ukuba ufanelekile namhlanje. Angaqondakali ukuthenga iyunithi nkqubo ayikho (kukho izisombululo omtsha nenzuzo ngaphezulu). Kodwa nantsi i nokuphuculwa PC, lukhuni kakhulu. izibonelelo zalo ilizwe, yonke ngokwaneleyo ukuphumeza phantse nawuphi na umsebenzi.
