Overview na processor Intel Core i7-870: description, fasali da kuma sake dubawa

Flagship tsakiyar aiki naúrar "Kor i7 870" daga kamfani "Intel" samar a cikin shekarar 2009, wanda har yanzu shi ne iya ba tare da wahala warware ko da ga mafi hadaddun ayyuka za a bincika a daki-daki a cikin wannan abu. Akwai ma za a ba da karfi da kuma kasawan na semiconductor crystal.

Na yi iya wannan guntu? Its kasuwar kashi

A jaddadawa da fasaha shirin na "Kor i7 870" ci gaba da zama har yanzu dacewa da kuma warware wasu matsaloli ba tare da wani matsaloli, ciki har da mafi rikitarwa. A wannan yanayin, babu wani musamman bukatar kara agogon mita na ta (ie, "overclock" da silicon guntu). Ya hudu aiki module farko aiki a agogo mita na wani sosai m da sauri maras tabbas memory subsystem a cikin kungiyar ba ya bambanta daga yanzu sarrafawa. A sakamakon haka, muna samun daya daga cikin mafi m guntu 2009, wanda bayan shekaru 7 daga farkon tallace-tallace ci gaba da zama dacewa.

CPU Zabuka

Intel Core i7 870 da aka sayar a cikin biyu daban-daban versions na sanyi. More Saukake da m daga gare su rababbe matsayin "Treil '." A wannan yanayin, da mai amfani na'am da umarnin don amfani tare da katin garanti, iri lakabin iyali na semiconductor kwakwalwan kwamfuta da guntu kanta. Zabi na biyu da sanyi da ake kira "Box", kuma shi ne mai boxed version na tsakiyar aiki naúrar. Yana hada, a Bugu da kari ga baya aka ambata aka gyara zuwa ga previous version of sanyi, a matsayin ma'aji mai sanyaya, dauke akwatin da kuma thermal manna.

A farko bambance-bambancen sanyi mafi alhẽri ya dace da kwamfuta masu goyon baya da kuma overclockers, wanda zai iya saya wani ci-gaba da sanyaya tsarin da haka kara da karshe wasan kwaikwayon na kwamfuta tsarin. Amma da boxed version na sanyi mafi kyau dace domin talakawa masu amfani, da kuma abin da ainihin aikin wannan bayani ya quite isa.

soket

Intel Core i7 870 da aka mayar da hankali a kan shigarwa na fi ci-gaba a cikin soket 2009 da kamfani "Intel" ga kwamfuta shigarwa-matakin mafita - LGA1156. Kuma shi ne daya daga cikin mafi m sarrafawa na dandali. Ainihin sa na dabaru, a wannan yanayin kunshi daya kawai Southbridge - P55. A arewa gada da aka mayar da su cikin guntu jiki. A kadan daga baya, akwai wasu chipsets ga wannan dandali - N57 Express da kuma H55 Express. A gaskiya, shi ne guda kamar yadda P55, amma Bugu da kari na graphics subsystem. Optimally a tare da tare da CPU da aka yi amfani da ita P55, wanda ya quite isa na dama ga fadada wannan high-yi semiconductor mafita.

aiwatar

Core i7 tsakiyar aiki naúrar 870 da aka sanya bisa ga aiwatar da dokoki (45 nm), wanda ya kasance a shekara ta 2009 godu ci gaba. Yana ya wuce tun shekaru 7 da kuma daina aiwatar (14 nm) amfani da a samar da ci-gaba kwamfuta mafita. Duk da irin wannan babban bambanci, wannan high-yi guntu ci gaba da zama dacewa da kuma ba tare da wani matsaloli iya warware wata matsala ko da a yau.

cache

High CPU Core i7 870 kamata a sanye take da uku-matakin cache ne m. In ba haka ba, ba zai iya warware ta ƙara wuya daga cikin matsala, ko da a shekarar 2009. A wannan yanayin, da ajiya iya aiki kamata kuma ya kasance mai kyau size.

A sakamakon haka, zane injiniyoyi sun sanye take da shi kamar haka:

• A farko matakin ga kowane core da aka ƙaddamar ya kasu kashi 2 sassa kayayyaki 32 kb. Daya daga cikin su an qware a cikin ajiya na CPU umarnin, da kuma na biyu - a kan ajiya na bayanai. Wannan shi ne, wanda zai iya amfani da mai aiki da na'urar kwamfuta module 64 kb a total. To, tun da jimlar yawan tsakiya ne daidai da 4, sa'an nan muka samu 4 * 64 = 256 kbps.

• Na biyu matakin ya ba da irin wannan m specialization a kan irin adana bayanai, amma aka raba tsakanin mutum kernels. The damar kowane kwamfuta naúrar ne daidai 256kb. To, a cikin ware Naira Miliyan Xari na yawan size ne 1 MB (4 zuwa 256 KB tsakiya).

• The uku cache matakin ne ga kowa da kowa CPUs. Its size ne daidai da 8 MB.

Random-access memory

I7 CPU 870 da aka mayar da hankali a kan yin amfani da mafi m a lokacin kamar bazuwar damar žwažwalwar - "DDR3". manufacturer kansa Nagari bundled da wannan CPU amfani "DDR3-1066" tube ko "DDR3-1333". A yi, shi yiwuwa a sa mafi gudun RAM kayayyaki na wannan irin, amma ba su kasance ba su iya aiki da sauri "DDR3-1333". Matsakaicin adadin RAM, wanda da processor za a iya jawabi a wannan yanayin ne 16 GB.

Wani muhimmin fasaha nuance - hadewa na dual-tashar memory mai kula da semiconductor guntu CPU. Wannan aikin injiniya bayani ya muhimmanci ƙãra wasan kwaikwayon na karshe kwamfuta tsarin.

A zafin aiki na semiconductor guntu. TDP

A iyakar halatta zafin jiki ga "Kor i7 870" da aka daidaita 72,7 digiri. Yawancin lokaci, a yi, wannan nufi da cewa sanyaya tsarin ga wani dalili ne daga oda. A al'ada aiki yanayin, da zazzabi daga cikin guntu ne a cikin kewayon 40-55 digiri. Idan ka overclock wannan flagship processor, sa'an nan da zazzabi tsarin mulki canji. A wannan halin da ake ciki, shi zai kasance a cikin zangon daga 50 zuwa 60 digiri. Don shawo kan m darajar 60 digiri za a iya gudu mafi wuya software. Amma har a cikin irin wannan halin da ake ciki, da zazzabi da wuya ke bayan da ya halatta iyaka da kuma wuce 70 digiri. Zafi da kunshin wannan guntu ya daidaita zuwa 95 watts.

mita dabara

Wannan guntu aka sanye take da irin wannan fasahar a matsayin "Turbo Boost". Saboda haka, ta Agogon mita canza dangane da wuya daga cikin matsalar da ake warware, da yawan aiki aiki albarkatun da thermal jihar na CPU. A reference Agogon mita a dagagge zafin rana masha'a a Core i7 870 - 2,93 GHz. Bi ta darajar - 3.2 GHz.

A wannan yanayin, da zarar duk 4 kayayyaki aiki a duka halaye. Kawai a cikin farko idan akwai wani karu saboda zafi fiye da kima daga cikin guntu, ko saboda saukin matsalar, da kuma na biyu - a duk sauran yanayi inda kana bukatar ka je dama 4 tsakiya. A gaba darajar - 3,47 GHz. A miƙa mulki ga wannan yanayin a cikin processor disconnects 2-sarrafa kwamfuta kayayyaki. Matsakaicin mita a wannan harka shi ne 3.6 GHz. The kwamfuta tsarin aiki ne kawai 1 thread.

architecture

A code sunan mai aiki da na'urar kwamfuta raka'a guntu - Nehalem. Wannan CPU hada nan da nan 4 tsakiya. Bugu da kari, a rarrabe semiconductor yin jerin "Kor Ay7" shi ne don tallafa wa mallakar tajirai fasahar, code-mai suna "wuce-wuri Trayding", wanda damar kan daya jiki core don samun 2 dabaru (ie, a shirin matakin). Wannan semiconductor guntu a cikin wannan yanayin ne ba togiya. A sakamakon haka, a cikin software matakin shi nuna 8 nan da nan sarrafa kwamfuta zaren.

Duk da wannan damar da shi har ma a yanzu, ba tare da da yawa wahala a magance da wani aikace-aikace software (duka gyara domin Multi-Threaded hardware, ko ba).

hanzari

A ka'idar, shi yiwuwa a aiwatar da wasu daga yin amfani da Intel i7 870. System bas overclocking Amma a yi da manufacturer da wannan manufa da shawarar yin amfani da wani jerin kwakwalwan kwamfuta "Kor Ay7 9xx", wanda kuma yana da prefix "Black Edishon".

A cikin hali na "Kor Ay7 8xx" yi matakin da shi ya wuce kima da farko, da kuma haifar da gagarumin ƙarin load a kan kwamfuta tsarin da aka gaba ɗaya da bai dace ba. Yanzu wasan kwaikwayon na CPU za a iya kiyasta kamar yadda isa. Yana ba ka damar gudanar da wani software, wanda shi ne a wannan lokacin.

User reviews. CPU kudin

The kawai drawback, wanda zai iya zama da processor Premium matakin - wannan shi ne babban kudin. Manufacturer ta bada shawarar farashin da aka daidaita $ 305. Amma dole ne mu gane cewa ingantaccen abu zai iya ba kudin dinari. Saboda haka a cikin wannan harka - wani guntu-to-date fiye da shekara guda, dole ne tsada. Ga sauran, a cikin wannan CPU yana da kawai abũbuwan amfãni. Wadannan sun hada da wasan kwaikwayon, thermal yanayi da kuma ayyuka.

Ko m Intel mita i7 870 2 93 GHz damar yin amfani da mafi yawan data kasance software. To, game da wata high-gudun yanayin, kuma ba mu zamo magana - su kara ƙara yawan aiki.

sakamakon

Fasaha sigogi "Kor i7 870" har yanzu ci gaba da zama dacewa a yau. Make yawa ji saya a tsarin naúrar ba (akwai wani karin riba sabon mafita). Amma a nan shi ne wani inganci da PC, kuma impractical. Its albarkatun muddin isa ya yi kusan duk wani aiki.
