Amagqabantshintshi iprosesa Intel Core i5-750: iinkcukacha, iinkcazelo kunye nohlolo

2009 wabona ukukhululwa kumqhubekekisi izakhiwo ezihlaziyiweyo Lynnfield, ummeli inkoliso yazo yayifumaneka ngexesha nj 'Kor i5-750 ». Iimpawu le mveliso semiconductor ayikho ezahlukeneyo ukusuka CPU quad-core namhlanje kulo kumvelisi ukuze kakhulu. Ngoko ke, lo CPU usaqhubeka ukuba efanelekileyo yaye ukucombulula uninzi iingxaki zonke iintlobo ngalo mzuzu.

iprosesa market Niche, nto leyo iye yajolisa Isimilo kubuyekezwa

Ngenxa LGA1156 «Intel" iqonga market encinane yahlulwe nengxenye zilandelayo:

• PC entry-level esekelwe iziqhubekisi Celeron (ezi chips zinika inqanaba elincinane lomsebenzi ezaneleyo we computers ofisi) kunye Pentium (kulo mzekelo, akwazi nokuba ukubala phezu ngokusesikweni ezinye zokudlala ezintsha izicwangciso iphantsi, kodwa umdlalo ukuze inkqubo unit i nga ngokuba a elula ). Umahluko phakathi kwezi mveliso ezimbini ukunyusa ubungakanani cache, nokwandisa amaza iwotshi yokusebenza iprosesa, kwaye kusenokwenzeka ukuba ufumane ku umkhuba isantya umdla olongezelelweyo.

• yee-level ingxenye wathabatha iintsapho chips i3 kunye i5. Kuyinto kweli qela ababekolo CPU yaye kuqwalaselwa njengenxalenye yale yesisombululo iprosesa eziphathekayo. imodeli i3 omncinane kuquka iyunithi kuphela-2 kuphela ikhowudi processing emzimbeni. Kodwa ekubangeleni ht nobuchwepheshe obuphuma nj semiconductor kumgangatho software na ukuba asebenzise ulwazi imisonto 4. Apha kukugcwalisa iziqhubekisi i5 4 umphakathi emzimbeni. Kufuneka kwakhona ubungakanani efihlakeleyo memory yandisiwe yaye yaqaliswa TurboBoost technology inkxaso. Le yokugqibela ikuvumela ukunyenyisa amaza CPU ngokuxhomekeke iqondo oluvela ikhowudi multithreading, urhulumente wobushushu chip semiconductor kunye nomgangatho ukuntsonkotha umsebenzi owenziwayo.

• Iiyunithi Inkqubo aveza imveliso, bobabini emva koko kwaye ngoku isekelwe kwi intsapho chips i7. Baye unit 4 ikhowudi processing emzimbeni, kodwa inkxaso technology ht ivumela software ukufumana inqanaba zezingxoxo 8. Kwakhona, ifomula frequency kule meko luyanda njengoba ye-cache.

Nangona ngokusesikweni uTshawe kubuyekezwa yaye libhekisela iimveliso processing abakumgangatho ophakathi, Noko ke, phakathi phantse zonke ezikhoyo ngelo xesha software na lula ukukhuphisana yavulel flagship. Uninzi software kanye ngoku swi ukusetyenziswa 4 umphakathi emzimbeni, yaye ngenxa yesi sizathu ayikho ngoku ikhona eninzi umahluko ngokwemigaqo yokusebenza phakathi CPUs amadala umenzi.

Package Contents

Le mveliso kuthengiswa ngombala ezimbini. Okunye wayengaphakamanga kubo ngokuba Itreyi. Kulo mzekelo, ngaphandle CPU uzuza yesikhokelo, ikhadi iwaranti kunye sticker kunye negama imodeli chip ngenxa yolawulo ngaphambili. izixhobo enjalo ejoliswe ikakhulu kokuba abaqokeleli ezinkulu leeyunithi nkqubo, kodwa ke ngamanye amaxesha abe bathandi computer. A ngobuwena yesibini le mveliso iprosesa uqwalaselo ebizwa BOX. Udibi igama "kweebhokisi 'ofana naye. Kulo mzekelo, uluhlu uye kuthi yongezwe unikezelo liphole ucole thermal.

CPU socket

Kuba kuzo LGA1156 socket kuye kwanikelwa ingqalelo "Kor i5-750». Iimpawu kwezisekelo lubonise ukuba wajolisa ibandla a ibhloko inkqubo-chip. Le socket uvumelekile ngo-2009 ukuya ukulungiselela injongo eyahlukileyo ngokupheleleyo kunye neendleko kweenkqubo intanethi. Eli qonga khompyutha kuhlala efanelekileyo de-2011, xa kungena amanye LGA1155. Kodwa ke, iimveliso kolu ngcelele kuqhubeka ukuba ufanelekile ukuba ubuncinane omnye isizathu sokuba umgangatho womsebenzi wabo kodwa uyasivumela ukuba ukusombulula iingxaki ezininzi.

i semiconductor chip technology lokuvelisa

Ngokutsho iteknoloji eqhelekileyo ekuqaleni kuka-2009 wavelisa "ezingundoqo i5-750». Iimpawu zonke esi sizukulwana chips zibonisa ukuba eziveliswa yinkqubo 45-NM technology. Yena ngelo xesha asebenza kakuhle, yaye akazange kuvela naziphi na iingxaki elibalulekileyo isivuno ezisicaba lesilicon kule meko. Kamva indawo iteknoloji kunye nezithethe kokunyamezela ka 32 NM.

Kesh

Njengazo zonke iimveliso mihla iprosesa eziphuhlileyo, inqanaba ezintathu-cache Intel i5-750. Iimpawu le mveliso semiconductor kulo mzekelo zimi ngolu hlobo lulandelayo:

• Inqanaba lokuqala luquka inxalenye 4 64 KB, ibotshelelwe kumnqongo computing ethile.

• Ngokufanayo ahlela iibhloko ezi-4 256 KB kwinqanaba lesibini.

• Le efihlakeleyo lememori kwinqanaba wesithathu eqhelekileyo zonke izibonelelo CPU yaye nobungakanani bubonke 8 MB.

imemori yofikelelo oluzenzekelayo

Ngokubonakalayo imemori esezantsi iye ngokutsha kwi izigqibo ngokusekelwe LGA1156, kuquka ezikumaNqanaba anguNdoqo i5-750. Iimpawu le mveliso ibonise ukuba ibhulorho ngasentla kunye eli memory iye isusiwe motherboard ukuya CPU semiconductor chip. Kuyenzeka ukuba ngokuphawulekayo ukwandisa isantya RAM. Kodwa ke, kwelinye icala, inkumbulo isilawuli ukuhlanganiswa kuthethe ukuba chip akwazi ukusebenza kuphela kuphela uluhlu ethile lwe memory imivalo. Kulo mzekelo, iseti ayenza DDR3-1066. Kwakhona kukhatshwa CPU zingasetyenziswa kunye nememori khadi-ephakamileyo isantya, kodwa nezihlandlo umsebenzi wabo kuphela ukuba ixabiso enye kuphela - ngo1066 MHz. Into ngakumbi kulo mzekelo ayikwazanga ifunyenwe.

uluhlu Ubushushu. TDP

On the TDP kwi kumqhubekekisi 95W i5-750 yabalelwa. Iimpawu yale CPU modeli kubonisa ixabiso lobushushu avumelekile ubuninzi degrees 72. Kwimo eziqhelekileyo, indlela lobushushu chip enokuthintela amaxabiso degrees 40-50. Kwimeko le uluhlu kuyenyuka ukukhawulezisa yaye sele ngaphakathi kwimida degrees 50-60. Ukuziqhelisa, umthwalo CPU njengoko elimiselweyo kuluhlu zokusebenza, ukuze ifike Ixabiso elikhulu Yayingekho. Ukuya ngaphaya kwemida emiselwe kwenzeka kuphela kwiimeko ezimbini. Omnye wabo - ukusilela kwinkqubo zokupholisa, kwaye eyesibini - lunikezelo chip Kudibaniso kwesibandisi epheleleyo ziqaliswe PC ezininzi izicelo ngenkani.

amaza

Le 2.7 GHz yasekwa ixabiso frequency okokuqala i5-750 Intel Core. iimpawu Oku kwakubonisa kubuchwepheshe CPU inkxaso TurboBoost. Oko kukuthi, kumqhubekekisi uyakwazi ukunyenyisa rhoqo kwaye inani leeyunithi becomputing esebenzayo. Xa usebenzisa zonke iibhloko ezine ixabiso frequency ubuninzi kuphela ukuya 2.8 GHz. Ukuba iprosesa iqhutywa kwimo kabini, ixabiso frequency alinganayo 2,93 GHz. Kodwa xa omnye kuphela block ukwenza izibalo, eli xabiso ngokubanzi angavuka ukuya ku 3.2 GHz. Kwakhona, kwakukho kungenzeka ukuba overclocking CPU. Amava abonisa ukuba olufanelekileyo lwesimo inkqubo unit ayikwazanga ndikuchithachithe kumqhubekekisi ukuya GHz-4 kwaye ufumane ngale kwanda phantse-30% nesantya.

CPU Architecture

Njengokuba bekutshiwo ngaphambili, 4 emzimbeni imodyuli ikhowudi processing lubandakanya Intel Core i5-750. Iimpawu le mveliso ibonise ukuba akukho nkxaso technology HyperTrading. Ngoko ke, kwinqanaba software ukuba thaca yi imijelo 4 efanayo. Kwaye eli xabiso nanamhlanje usaqhubeka efanelekileyo ngenxa yokuba uninzi isoftware elungiselelwe ubuninzi zezingxoxo-2 okanye ka-4. Kulo mzekelo, umahluko kunye nosapho CPU i7 olubiza kakhulu nzima ngayo.

abanini uluvo. inani

I $ 213 kwavavanywa le loguqulelo Core i5. CPU 750 (iimpawu ngokwenene yaba kakhulu ngo-2009) ukuba ukusombulula naziphi na iingxaki. Kwaye nkqu ngoku CPU ngokulula ukuphatha phantse yonke imithwalo. Oku kuphela zokudlala zakutshanje ukuze iingxaki. Kodwa kulo mzekelo ukunciphisa umgangatho umfanekiso oboniswe, nto leyo eya ukutshonisa ngokupheleleyo ngokwabo kwi Ukudlala enkulu.

iziphumo

imveliso iprosesa Ufanele waba "Kor i5-750»-2009. Iimpawu siyaqhubeka namhla ukuba afanelekileyo kwaye wenze kube lula nangoku ukusombulula iingxaki ezininzi. Kwakhona, amancedo kwale modeli lwe CPU ufuna iindleko ezifikelelekayo, ubukho ukusebenza ezine emzimbeni iiyunithi ikhowudi kunye nokusebenza kuhle amandla sinochuku ukulungiselela unyaka ka-2009. Kodwa abanikazi zezi yunithi inkqubo kungekudala kakhulu ukuba bacinge malunga uphuculo ecwangcisiweyo inkqubo yekhompyutha.
