Intel Core 2 Duo E8400 Wolfdale: isishwankathelo, iinkcukacha, iinkcazelo kunye nohlolo

Umlinganiselo ixabiso, yaye imida kunyaka ka-2008 yi izisombululo umqhubekekisi Core 2 Duo E8400. Yaba amathuba bakhe kunye iinketho, kwakunye ukubuyekeza kuya kuxoxwa banzi kolu phononongo.

endaweni CPU

Xa iziqhubekisi 2008 ohlulwa ngale ndlela ilandelayo:

• izisombululo High-komsebenzi, olu sapho lwaluquka umphakathi 4. Ezi ziquka "Kor 2 Quad" kwi "Intel" yaye "ngumkhuba" ka "AMD". Ngoko nangoko kufanele kuphawulwe ukuba ezi chips kwanto kwizicelo multithreaded. Kodwa wesoftware a flow computing baphulukana iitshiphusi engundoqo enye, nto leyo yaba rhoqo ephakamileyo.

• Umyinge CPU ingxenye yaqaliswa izisombululo ezimbini-core. Ukususela "Intel" kule niche zezi "Kor 2 Duo" oko kukuthi, iqhawe review namhlanje lethu - Intel Core 2 Duo CPU E8400. Ukusuka "AMD", nayo, ingxenye imakethi okhokelwa-umnqongo ezimbini "ngumkhuba" kunye "Athlon". Ezi chips esebenza ngokugqibeleleyo njenge iinkqubo multi-azinamsonto, kunye ne-software, leyo tsolo ngumntu CPU elinye-core.

• Ingxenye yokuqala izisombululo olunye-core ahlala. Abameli "Intel" kwakukho "Pentiums" kunye "Celeron". Kodwa ngokwahlukileyo kubo: "AMD" yakhululwa "Athlone" yaye "Septrony".

iinketho

Kukho 2 iintlobo kweekhithi nikeza nj. Eyokuqala kwezi kwaba Itreyi. Yayithetha okulandelayo:

• CPU kwingxowa yeplastiki olukhuselayo.

• Warranty Card.

• Sticker kuba ngaphambili PC isisu semoto.

• Imiyalelo Operating.

Inguqulelo yesibini kwathiwa BOX. Oku kuquka, ukongeza kuluhlu okhankanywe ngaphambili, kwaye nkqu nenkqubo sokupholisa kunye paste thermal. Ngoku ke kufuneka ukuba kuqatshelwe ukuba injini wesiqhelo yenzelwe ukusebenza i CPU kunye parameters ibhengeze ngumvelisi. Kodwa overclocking Kucetyiswa ukuba usebenzise inkqubo Ukupholisa umoya eziphuculweyo.

Kwisokethi for chip

Chip Core 2 Duo E8400 olwalumiselwe engundoqo kunye nexesha kuphela kwisokethi CPU kwi "Intel" - isokethi 775. Kakade ke, lo motherboard entsha kusengenziwa kuthengelwa ngaye, kodwa isitokhwe ziikristale semiconductor kudala kuthengisiwe. Ngokwembono iimfuno ezikhoyo ngoku izibonelelo zekhompyutha PC ukuze kuqatshelwe ukuba kwicandelo mali eyabelwe kwizisombululo efanayo. Iinkqubo ezininzi ziya ukusebenza kuyo, kodwa hayi ekutshoneni ubuninzi.

ubuchwepheshe

Lo ngowokuqala, leyo yayenziwe 45 technology NM. Ngoku, ke, eli xabiso wokwamanani ayimangalisi. CPUs Modern zenziwa inkqubo lesilicon iteknoloji sele 14 NM. Kodwa ke ngo-2008, nengqungquthela wavumela zobunjineli ukunciphisa kwindawo chip nokunyusa inani transistors, mvisiswano leyo, kwelinye icala, ukuba ukwandisa intsebenzo kwinkqubo khompyutha 10-15 ekhulwini.

cache

Kakade ke, isicombululo iprosesa ophezulu ngo-2008 yaba Core 2 Duo E8400. Ngoko ke, waba ubungakanani ehlonelwayo level-ezimbini efihlakeleyo memory. inqanaba layo lokuqala ibotshelelwe ngqo kumnqongo ethile waba zahlulo-2. I yokuqala Inxalenye 32 KB isetyenziselwa ukugcina imiyalelo kunye okwesibini, kanye ziyalingana, idatha igcinwe. Kodwa efihlakeleyo kwinqanaba lesibini eqhelekileyo zombini computer kwaye ngaxeshanye igcina iinkcukacha kunye nemiyalelo. ubukhulu sayo 6MB kunye efanayo neempawu, asizizo zonke iprosesa ixesha na pohvatali.

imemori yofikelelo oluzenzekelayo

Njengoninzi iziqhubekisi isokethi 775, kodwa ke uhlobo olunye kuphela ye-CD inkxaso Core 2 Duo E8400. Iimpawu zibonisa ukukwazi kwakhe ukusebenza kuphela DDR2. Olu hlobo RAM iphelelwe zombini ngokuziphatha nasemzimbeni. Yena indawo kakhulu ixesha elide weza DD3, nto leyo ngoku ngcembe athathelwe DDR4.

Ngenxa yoko, ulindele intsebenzo olugqibeleleyo akayi kuza kulo izisombululo ezimbini-GPU: ephantsi rhoqo memory ukuba ncam isimo sentlalo eziya enokuthintela umsebenzi kwenkqubo yekhompyutha xa iyonke.

bokuqonda ubushushu

Le modeli ibango TDP na iiwathi ezingama-65. Eli xabiso asinto ingaqhelekanga nanamhlanje - kanye imvulophu efanayo wobushushu kuninzi Processors mihla. sivumelekile aphezulu enjalo lesilicon akhazimlayo lobushushu Iqondo lobushushu lihle laya 72,4. Ukusebenza eqhelekileyo i CPU kwi umthwalo eliphezulu, oko degrees 50. Kodwa xa overclocking ulawulo olungcono nakukubaluleka kwalo. Kudla kukho iimeko apho inkqubo sokupholisa abakwazi ukumelana ubushushu chip kunye kwithempritsha yayo phantse kweso kufika kumgomo 75-80. Emveni kwezi amalinge, i CPU abadli phantsi kwaye kufuneka ukuthenga CPU entsha kakade.

I-frequency nokusebenza

Eliyimali clock rhoqo Intel Core 2 Duo E8400 - 3,00 GHz. Ngokutsho kwesi salathisi E8400 phantse akukho ndlela obuphantsi mihla Pentium G3260, apho nani 3.3 GHz. Oko kukuthi, umlinganiswa PC-based le bangathunyelwa koomatshini ofisi yangoku. Kodwa ukuba indawo injini standard ukuphucula kwaye ukubeka ikhompyutha unikezelo lwamandla enamandla ngakumbi, kunokwenzeka ngaphandle naziphi na iingxaki ukuba overclock nj ukuya ku-4 GHz. Kwaye oku ukunyuka kakhulu intsebenzo kunye nesakhono ukuze isebenze phantse zonke zokudlala mihla, kuquka befuna (nakuba sikho akukho seto ubuninzi).

bokwakha

Njengoko kuchaziwe ngaphambili, oku kumqhubekekisi babephuma uhlelo of "Kor 2 Duo." Kwakugcwele ezimbini iyunithi computing bit-64, nganye nolusebenza kwi-frequency 3.0 GHz. Technology "Turbo Ukukhuthaza" kwi "Intel" ayixhaswa yi chip. Ngenxa yoko, wayengakwazi dynamically ukutshintsha isantya lwabo lwewotshi. Kukwasebenza kwanjalo kuyo ubuthongo unactuated kernel azo. Ngoko ke, ngokokusebenza kwamandla wesimanje-2-core chips E8400 kuya kuba nzima ukuba ukukhuphisana.

lunikezelo

I-Core 2 Duo E8400 weza yakha itshixiwe. Ngenxa yoko, ukunyuka elula umba kwakungenakwenzeka ukuba lisasazwe. Kulo mzekelo, kuyimfuneko ukunciphisa onke amacandelo rhoqo ngaphandle kwinkqubo ibhasi. esasidla yayo clock kwixesha elizayo ke kuyimfuneko ukuba ukwandisa kancinci. Ngaphandle naziphi na iingxaki kusenokwenzeka ukuba kukuzuza CPU 4 GHz. Noko ke, ngaphambi kokuba lo msebenzi elula, kuyimfuneko ukufakela software eyodwa yaba ( "AIDS-Fan 'ukuba ulawulo lobushushu kunye nenkqubo zokupholisa," CPU-Z "ukujonga inkqubela kumqhubekekisi amaxabiso rhoqo" yeAIDA 64 "lalisetyenziswa ukukhangela luvukelo ntshikilelo kwenkqubo yekhompyutha). Kwakhona, ukuba kuyimfuneko ukuba indawo kwindlela sokupholisa ye thuthu yaye yandiswa kwaye khangela iyunithi unikezelo lwamandla, leyo kufuneka ubuncinane 700 watts. Kuphela emva kokuba uqale ukuze lisasazwe. Ukuba kuyimfuneko, kwaba lula ukoyisa ngentla uthe umda kwi GHz 4, kodwa lo mzekelo kuyafuneka kukunyusa ngakumbi ombane ebebunikwe loo CPU, ukuya ku 1.4 V okanye ngaphezulu. Kwaye oku kakuhle, kwaye le mo yokusebenza yendawo E8400 semiconductor chip ukusilela ngokukhawuleza kakhulu. Ngoko ke, ezi amalinge enokwenziwa kuphela kwiimeko kakhulu.

inani

Ixabiso okuba CPU Core 2 Duo E8400 wayelingana eerandi 183 kwebhokisi version kunye iidola 153 ngenxa yetreyi version. Xa entanjeni ixabiso lokuthengisa zezi chips semiconductor yehle ngomyinge $ 4 waza waba ilingana 179 zeerandi (IBHOKISI) kunye $ 149 (kwitreyi yendlela). Ngo-2008-2009, yeendleko zezi chips iyavumelana ngokupheleleyo umgangatho womsebenzi wabo.

reviews

Ngokuchasene imvelaphi namanye amalungu ale yentsapho iziqhubekisi ixabiso kakhulu ngemali kunye neempawu uziqhenye E8400. Kuba 183 zeerandi unako ukuthenga yaxhobisa ngokupheleleyo Core 2 Duo E8400. 3,0 GHz iye clock frequency. chip thuthu enombhalo E8500 kuxabisa 266 zeerandi, kwaye rhoqo yayo ilingana no 3.16 GHz.

Oko kukuthi, ukuba 160 MHz ezongezelelweyo kwafuneka ukuba babeke $ 83. Ngamanye amazwi, le ntengo wakhula kakhulu, kunye nokusebenza babambanayo mncinci kakhulu. Abameli abancinane kule yentsapho iziqhubekisi - E8200 kunye E8190 - zibiza ngaphantsi kwe $ 20 (163 zeerandi), kodwa ke amaza baba MHz 2,66. Elo lixabiso baye zehla kancinane, kodwa ukusebenza - kubalulekile. Kungenxa yoko le nto abaninzi abasebenzisi, kwaye ukhethe ukuba E8400. Kuyinto le bokuqonda kwaye ibonisa uninzi ncomo umsebenzisi. Elokugqiba, u ta va a CPU elikhulu ixesha layo. Ntoleyo, koko, wayesenalo ukuqhayisa overclocking amandla kakhulu.

iziphumo

Isisombululo iprosesa elisemagqabini ngexesha layo, lo Core 2 Duo E8400. Yena kunye ixabiso leyo kakhulu lwentando yesininzi, kwaye inqanaba lokwenziwa komsebenzi kakhulu elungileyo. Kwaye ivumela overclocking olunokubakho nkqu ngoku ukusebenza kuyo, inkoliso software ekhoyo (nkqu ngaphantsi kwe izicwangciso ubuninzi). Konke oku ephawula iimveliso ombutho "Intel" kuphela icala okulungileyo: uthenga isisombululo mid-level - yaye kule minyaka 5-7 ezayo, intsebenzo ikhompyutha ngeke asinde.
