Naphezu kobunzima obusobala ekukhiqizeni ama-chips angu-14-nm ngenani elanele, i-Intel iyaqhubeka nokwandisa ngokuhlelekile uhlu lwayo lwama-Core processors esizukulwane sesishiyagalolunye, ebhalwe ngekhodi ye-Coffee Lake Refresh. Yiqiniso, lokhu unikezwa yena ngamazinga ahlukahlukene empumelelo. Okusho ukuthi, ngokusemthethweni, imikhiqizo emisha yengezwa ngempela kuhlu lwamamodeli, kodwa ibonakala ekuthengisweni kwezitolo ngokunqikaza, futhi amanye amamodeli avela phakathi kwemikhiqizo emisha eyethulwe ngokushesha ngemva koNyaka Omusha awakwazanga ukuvela emashalofini esitolo kuze kube manje. .
Kodwa-ke, ngokusekelwe kudatha esemthethweni, manje sekunamamodeli we-Core edeskithophu okungenani ayisishiyagalolunye yesikhulumi se-LGA1151v2, esochungechunge lwezinkulungwane eziyisishiyagalolunye, phakathi kwazo kukhona ama-processor anama-computing cores amane, ayisithupha nesishiyagalombili. Ngaphezu kwalokho, lo mndeni awubandakanyi nje abameleli abasobala abanezici ezingabikezelwa, kodwa futhi nama-CPU angalindelekile ahluke ngokwemibono kubo bonke abanduleli bawo. Sikhuluma ngama-F-series processors - ama-chips edeskithophu akhiqizwe ngobuningi, okucaciswa kwawo okungabandakanyi umongo wehluzo owakhelwe ngaphakathi.
Okumangazayo ngokubukeka kwabo ukuthi iminikelo enjalo yandisa uhla lwabathengi be-Intel okokuqala ngqa eminyakeni eyisishiyagalombili edlule, lapho inkampani inikela ngezixazululo ezikhethekile ngehluzo ezihlanganisiwe zengxenye enkulu. Kodwa-ke, manje kukhona okushintshile, futhi i-microprocessor giant iye yaphoqeleka ukuba icabangele kabusha izimiso zayo. Futhi siyazi nokuthi: ukubalwa kabi ekuhleleni nobunzima ekusebenziseni ubuchwepheshe benqubo ye-10-nm kuholele ekushodeni okukhulu kwama-Intel processors emakethe, inkampani ezama ngawo wonke amandla ayo ukuze inciphise. Ukukhishwa kwamaphrosesa ngaphandle kwehluzo ezihlanganisiwe kungenye yezinyathelo ezisobala ezihloselwe ukufeza lo mgomo. Ngenxa yalokho, umkhiqizi ukwazile ukufaka kumaphrosesa wokukhiqiza phambilini ayebhekwa njengezikhala ze-semiconductor ezinesici ezinomongo wehluzo owonakele, okuthi ngisho nakuma-30-core Coffee Lake Refresh "adle" kuze kufike ku-174% wendawo engu-XNUMX mm. ikristalu. Ngamanye amazwi, isilinganiso esinjalo singandisa isivuno semikhiqizo efanelekile futhi sinciphise kakhulu imfucuza.
Kodwa-ke, uma ku-Intel incazelo yokukhulula ama-F-series processors isobala, khona-ke ukuthi abathengi bayazuza yini ekubukeni kwalezi zinhlinzeko yinkinga ephikisana kakhulu. Amaqhinga akhethwe umkhiqizi angangokuthi amaphrosesa akhishiwe athengiswa ngaphandle kwanoma yisiphi isaphulelo, ngentengo efanayo nozakwabo “abaphelele”. Ukuze siqonde lesi simo ngokuningiliziwe, sinqume ukuhlola omunye wabameleli besizukulwane sesishiyagalolunye i-Core lineup, engenazo ihluzo ezakhelwe ngaphakathi, futhi sizame ukubheka izinzuzo zayo ezifihliwe.
I-Core i5-9400F, i-junior six-core processor yesizukulwane se-Coffee Lake Refresh, yakhethwa njengento yokufunda. Kunesithakazelo esikhethekile kule chip: eyandulelayo, , yayidume kakhulu ngesinye isikhathi ngenxa yesilinganiso sayo esikhanga kakhulu sokusebenza kwamanani. Imenyezelwe ngokusemthethweni ezinyangeni ezine ezedlule, i-Core i5-9400 (ngaphandle kwe-F egameni) inikezela ngamaza aphakeme kancane ngentengo efanayo, kodwa cishe akunakwenzeka ukuyithola uma ithengisiwe. Kodwa i-Core i5-9400F itholakala emashalofini yonke indawo, futhi, ngaphezu kwalokho, njengoba ukushoda akusebenzi kulo modeli, intengo yayo yangempela yokuthengisa iseduze ngangokunokwenzeka kuleyo enconyiwe. Kodwa-ke, lokhu akwenzi ngokuzenzakalelayo i-Core i5-9400F ibe inketho enhle yokucushwa "okuyisisekelo", ngoba i-AMD manje inikeza ama-processor ayisithupha e-Ryzen 5 esigabeni samanani esifanayo, okuthi, ngokungafani nabameleli bochungechunge lwe-Core i5, abe nokusekela. i-multi-threading (SMT) . Kungakho ukuhlolwa kwanamuhla kuthembisa ukuthi kuzoba nokufundisa okukhethekile: kufanele kuphendule imibuzo eminingana ngesikhathi esisodwa futhi kubonise ngokusobala ukuthi i-Core i5-9400F inethuba lokuphinda impumelelo ye-Core i5-8400 edume.
Uhlelo lweCoffee Lake Refresh
Kuze kube manje, sekuvele kunamagagasi amabili ezimemezelo zamaphrosesa ahlukaniswa ngokwejwayelekile njengesizukulwane seCoffee Lake Refresh. Naphezu kweqiniso lokuthi ama-CPU anjalo afana ngezindlela eziningi nabawandulelayo abavela emndenini we-Coffee Lake, i-Intel iwahlukanisa njengesizukulwane sesishiyagalolunye i-Core futhi iwabala ngezinkomba eziqala ngenombolo 9. Futhi uma ihlobene ne-Core i7 ne-Core i9 enjalo. ukuhlukaniswa kungase kuthethelelwe ngokwengxenye, Phela, ngokokuqala ngqá bathola ama-cores ayisishiyagalombili e-computing, ama-processor amasha ochungechunge lwe-Core i5 ne-Core i3 bathole ukwanda kwezinombolo zamamodeli, ikakhulukazi enkampanini. Empeleni, banikeza kuphela isivinini sewashi esikhulisiwe.
Ngesikhathi esifanayo, asikho isidingo sokukhuluma nganoma yikuphi ukuthuthukiswa ezingeni le-microarchitecture nhlobo. Futhi, ukukhuluma ngokungananazi, lokhu akubangeli neze ukumangala. Umqondo wokuthuthuka owenziwa yi-Intel ungangokuthi izinguquko ezijulile kumaphrosesa ziboshelwe ekuthuthukisweni kobuchwepheshe bokukhiqiza. Ngakho-ke, ukubambezeleka kokwethulwa kobuchwepheshe benqubo ye-10nm kusho ukuthi kufanele siphinde sibhekane ne-Skylake microarchitecture, eyakhululwa ngo-2015. Nokho, okunye okumangazayo: ngasizathu simbe, i-Intel ayifuni ukushintsha izici ezingadingi izinguquko ezibonakalayo. Isibonelo, ngokusemthethweni i-Coffee Lake Refresh iyaqhubeka nokugxila kumemori yeziteshi ezimbili ze-DDR4-2666, kuyilapho isikhathi ne-AMD sengeza ukusekelwa kwezindlela zejubane eliphezulu kumaphrosesa ayo, ifinyelela ku-DDR4-3200 ezinguqulweni zakamuva ze-Raven Ridge. Okuwukuphela kwento eyenziwa yi-Intel ekuphenduleni kwakuwukukhulisa inani lememori elisekelwa ezinhlelweni ezisuselwe ku-Coffee Lake Refresh kuya ku-128 GB.
Kodwa-ke, naphezu kokuntuleka kwezinguquko ku-microarchitecture, i-Intel kuze kube manje ikwazile ukukhiqiza amamodeli athakazelisa kakhulu isebenzisa izindlela ezibanzi - ikhulisa inani lama-computing cores namafrikhwensi wewashi. Igagasi lokuqala lezimemezelo zeCoffee Lake Refresh, ezenzeka ngo-Okthoba nyakenye, lafika namaphrosesa amathathu e-flagship overclocking anqobe imingcele emisha yokusebenza: i-Core i9-9900K eyisishiyagalombili ne-Core i7-9700K, kanye neziyisithupha- i-core Core i5-9600K. Ngesesibili, igagasi likaNcibijane, uhlu lwabaphrosesa abasha lugcwaliswe ngamamodeli alula ayisithupha e-CPU. Ngenxa yalokho, uhla olugcwele lweCoffee Lake Refresh lwaqala ukubukeka kanje.

Inqwaba yama-processor, angezwe kumamodeli we-K-overclocking akhishwe kamuva, ahlanganisa ama-chips angenawo umgogodla wezithombe ohlanganisiwe. Ngobuchwepheshe, i-Core i9-9900KF, i-Core i7-9700KF ne-Core i5-9600KF zisekelwe kusisekelo se-semiconductor efanayo ncamashi futhi anezici ezifanayo ngokuphelele njenge-Core i9-9900K, i-Core i7-9700K ne-Core i5-9600K, ehluke kuphela ukuthi abanikezeli nge-GPU eyakhelwe ngaphakathi, ekhiyiwe kuhadiwe esigabeni sokukhiqiza.
Kodwa ohlwini lwemikhiqizo emisha yegagasi lesibili ungabona futhi amamodeli amasha ngempela. Okokuqala nje, lena i-Core i3-9350KF - okuwukuphela kwe-quad-core processor ene-multiplier evuliwe phakathi kwe-Coffee Lake Refresh. Uma uvala amehlo akho ekuntulekeni kwe-GPU eyakhelwe ngaphakathi, ingathathwa njengenguqulo ebuyekeziwe ye-Core i3-8350K, esheshiswe ngokungeza ubuchwepheshe be-Turbo Boost 2.0 kanye nekhono elisha lokuzidlula ngokuzenzakalelayo ku-4,6 GHz.
Omunye umkhiqizo omusha ogcwele noma ogcwele ngokuphelele kugagasi lesibili ungabhekwa njenge-Core i5-9400 kanye nomfowabo u-Core i9-9400F, ongenazo ihluzo ezakhelwe ngaphakathi. Inani lala mamodeli liseqinisweni lokuthi ngosizo lwayo, i-Intel yehlise kakhulu izindleko ze-Coffee Lake Refresh encane enezisekelo eziyisithupha, okuvumela ukusetshenziswa kwesizukulwane sakamuva sama-CPU ekucushweni kwezinga lesisekelo. Kodwa-ke, awukho umehluko omningi osemthethweni phakathi kwe-Core i5-9400 nokushaya konyaka odlule, i-Core i5-8400. Amafrikhwensi ewashi anyuke ngo-100 MHz kuphela, okungenzeka ukuthi kungenxa yesifiso se-microprocessor giant sokugcina amaphrosesa aso amancane ayisithupha ngaphakathi kwephakheji eshisayo engu-65-watt. Ngenxa yalokho, igebe kumafrikhwensi aphezulu we-turbo phakathi kwamaphrosesa ayisithupha amadala nabancane emndenini we-Coffee Lake Refresh liye lenyuka laya ku-500 MHz, kuyilapho esizukulwaneni se-Coffee Lake bekungu-300 MHz kuphela.
Ngokusekelwe ekucacisweni, umuntu uthola umuzwa wokuthi akukho lutho olukhethekile lokukhalipha i-Core i5-9400 entsha ne-Core i5-9400F ngokumelene ne-Core i5-8400 endala. Nokho, imininingwane kuleli cala ayinikezi isithombe esiphelele. Ngesikhathi kumenyezelwa i-Coffee Lake Refresh yokuqala, i-Intel iphinde yakhuluma ngezinzuzo ezingaqondile. Isibonelo, esizukulwaneni esisha sama-chips, kwathenjiswa ushintsho ku-interface yangaphakathi yokushisa: indawo ye-polymer thermal paste yayizothathwa yi-solder esebenza kahle kakhulu engena-flux. Kodwa ingabe lokhu kunento yokwenza nama-Core processors amancane esizukulwane sesithupha? Kuvele hhayi njalo.
Imininingwane mayelana ne-Core i5-9400F
Kwenzeka lokhu nje lapho ikhulula ama-processor we-Coffee Lake Refresh, i-Intel yahlanganisa izinketho eziningi ezahlukene zamakristalu e-semiconductor ngobuchwepheshe benqubo ye-14++ nm, futhi akuzona zonke ezintsha. Ama-Core processors esizukulwane sesishiyagalolunye angase asekelwe kuwo womabili amakristalu e-semiconductor aklanyelwe wona ngokukhethekile, kanye nezinguqulo ezindala kakhulu ze-silicon, ezasetshenziswa ngenkuthalo, okuhlanganisa namaphrosesa esizukulwane sesishiyagalombili, ahlukaniswa njengomndeni weCoffee Lake.
Ikakhulukazi, okwamanje kuyaziwa ngokuba khona okungenani kwamakristalu amane anyathelayo afakwe kuma-Core processors akhiqizwa ngobuningi anezinombolo ezivela ochungechungeni lwezinkulungwane eziyisishiyagalolunye:
- I-P0 ukuphela kwenguqulo “ethembekile” yekristalu namuhla, engabizwa ngempela ngokuthi I-Coffee Lake Refresh. Le crystal inama-computing cores ayisishiyagalombili futhi isetshenziswa kuma-overclocking processors i-Core i9-9900K, i-Core i7-9700K ne-Core i5-9600K, ezinhlobonhlobo ze-F-Core i9-9900KF, i-Core i7-9700KF ne-Core i5-9600KF, kanye ku-processor Core i5-9400;
- I-U0 iyikristalu enamakhanda ayisithupha, ngaphambili eyayisetshenziswa kuma-processor we-Coffee Lake, okungukuthi, ku-Core yesizukulwane sesishiyagalombili. Manje isetshenziselwa ukwakha i-Core i5-9400F eyisisekelo eyisithupha;
- I-B0 iyi-quad-core chip esetshenziselwa ama-Core i3-9350K processors. Le nguqulo ye-silicon iphinde yavela ngokuqondile kuma-quad-core Coffee Lake processors, kuhlanganise ne-Core i3-8350K;
- I-R0 iyisinyathelo esisha lapho kulindeleke ukuthi ama-Core processors amadala esizukulwane sesishiyagalolunye adluliselwe, kusukela ngoMeyi. Okwamanje, ayitholakali kuma-CPU we-serial, ngakho-ke alukho ulwazi oluthile mayelana nezici zayo nezizathu zokubukeka kwayo.
Ngakho-ke, i-Core i5-9400F, esikhuluma ngayo kulokhu kubuyekezwa, iyimvu emnyama: iprosesa eyodwa ehlukile ngesakhiwo sangaphakathi kwabanye abazalwane abayisithupha-core kanye nesishiyagalombili-core. isizukulwane seCoffee Lake Refresh. Uma sikhuluma ngokuqinile, akuyona inguqulo ehlutshiwe noma eyehlisiwe ye-Core i5-9600K noma i-Core i5-9400, kodwa inguqulo ethe ukuvaleka kancane ye-Core i5-8400 endala enomongo wehluzo ukhutshaziwe.
Futhi kufanele ngisho, lokhu akubonakali kuphela ezithombeni-skrini zezinsiza zokuxilonga, ezizobonisa i-U5 endala esikhundleni se-P9400 entsha ye-Core i0-0F. I-Core i5-9400F ayinakho ngempela ukuqanjwa kabusha kweCoffee Lake Refresh. Ikakhulukazi, lapho kuhlanganiswa lawa ma-chips, ikristalu ayithengiswa kukhava yokusabalalisa ukushisa, futhi isixhumi esibonakalayo esishisayo sifana ncamashí ne-polymer thermal paste eyayisetshenziswa kuma-processor we-Coffee Lake.
Ngaphezu kwalokho, i-Core i5-9400F, ngokungafani namanye amaphrosesa esizukulwane seCoffee Lake Refresh, ihlanganiswa ebhodini lesifunda eliphrintiwe eline-PCB ezacile - efanayo naleyo esetshenziselwa i-Coffee Lake evamile.
Ngaphezu kwalokho, ngisho nokuma kwesembozo sokusabalalisa ukushisa kwe-Core i5-9400F kuveza ubudlelwano bale processor ne-Core yesizukulwane sesishiyagalombili. Phela, ikhava ye-Purebred Coffee Lake Refresh isishintshile.
Ngamanye amazwi, akungabazeki ukuthi i-Core i5-9400F empeleni akuyona i-Coffee Lake Refresh, kodwa ukwenqatshwa kwamaphrosesa esizukulwane sangaphambilini esinomgogodla wehluzo okhubazekile. Ngaphezu kwalokho, lokhu kusebenza ku-5% wabo bonke abahlinzekwe njengamanje nge-serial Core i9400-5F, echaza kakhulu ukutholakala okubanzi kwalawa maphrosesa ngesikhathi lapho izinkinga eziphawulekayo ziqhubeka nokubonwa ngokuhlinzekwa ngobuningi kwezinye i-Coffee Lake Refresh. Isibonelo, umfowabo "ophelele" one-UHD Graphics 9400 edidiyelwe, eyamenyezelwa ngokusemthethweni kanye ne-Core i630-0F, okufanele isekelwe kukristalu "othembekile" we-PXNUMX, ayitholakali ukuze ithengiswe.
Ngesikhathi esifanayo, i-microprocessor giant ayibandakanyi ithuba lokudlulisela i-Core i5-9400F ekunyatheleni "okulungile" kwe-P0 esikhathini esimaphakathi. Kodwa lokhu kuzokwenzeka, ngokusobala, kuphela lapho zonke izinkampani zeCoffee Lake ezinqwabelene ezindaweni zokugcina izimpahla zenkampani yeCoffee Lake ene-GPU eyakhelwe ngaphakathi enesici sezithengiswa ngempumelelo.
Kodwa-ke, kubasebenzisi abaningi leli qiniso lokukhohlisa amakristalu e-silicon cishe akunakwenzeka libe nanoma yikuphi ukubaluleka. Noma kunjalo, i-Core i5-9400F iyiphrosesa yeqiniso eyi-100-core ngaphandle kokusekelwa kwe-Hyper-Threading, egijima ngo-5 MHz ngokushesha kunowandulelayo, i-Core i8400-5, ngaphansi kwanoma yimuphi umthwalo. Lokhu kusho ukuthi ngokuya ngefomula yemvamisa, i-Core i9400-10F ihambelana ne-Core i5-8500 ebiza kakhulu engu-$XNUMX.
Ngaphandle kweqiniso lokuthi i-Core i5-9400F ifuna imvamisa yesisekelo esiphansi kakhulu esingu-2,9 GHz, empeleni le processor iyakwazi ukusebenza ngokushesha kakhulu ngenxa yobuchwepheshe be-Turbo Boost 2.0. Nge-Multi-Core Enhancements enikwe amandla (okungukuthi, kumodi yokuzenzakalelayo yobuningi bamabhodi omama), lapho ilayisha ngokugcwele i-Core i5-9400F iyakwazi ukugcina imvamisa engu-3,9 GHz, ishesha ifike ku-4,1 GHz ngaphansi komthwalo womgogodla owodwa.
| Isilinganiso sokuvama | Imvamisa enkulu ye-Turbo Boost 2.0 | ||||||
| 1 umongo | 2 amakhora | 3 amakhora | 4 amakhora | 5 amakhora | 6 amakhora | ||
| I-i5-8400 | I-2,8 GHz | I-4,0 GHz | I-3,9 GHz | I-3,9 GHz | I-3,9 GHz | I-3,8 GHz | I-3,8 GHz |
| I-i5-8500 | I-3,0 GHz | I-4,1 GHz | I-4,0 GHz | I-4,0 GHz | I-4,0 GHz | I-3,9 GHz | I-3,9 GHz |
