Yintoni emangalisayo malunga nenkangeleko yabo kukuba iminikelo enjalo yandisa uluhlu lwe-Intel lweeprosesa zabathengi okokuqala ngqa kule minyaka isibhozo idlulileyo, apho inkampani inikezela ngezisombululo ezikhethekileyo kunye nemizobo edibeneyo yecandelo lobuninzi. Nangona kunjalo, ngoku kukho into etshintshileyo, kwaye i-microprocessor giant iye yanyanzeliswa ukuba ihlolisise imigaqo yayo. Kwaye siyazi nokuba: ukubala okungalunganga kucwangciso kunye nobunzima ekugunyaziseni itekhnoloji yenkqubo ye-10-nm kukhokelele ekunqongophelweni okukhulu kweeprosesa ze-Intel kwimarike, leyo inkampani izama ngamandla ayo onke ukuyithoba. Ukukhutshwa kweeprosesa ngaphandle kwemizobo edibeneyo yenye yemilinganiselo ecacileyo ejoliswe ekufezekiseni le njongo. Enkosi kuyo, umenzi wakwazi ukufaka kwiiprosesa zemveliso ngaphambili ezazijongwa njengeziphazamiso ze-semiconductor ezingenanto kunye nengundoqo yegraphics eyonakeleyo, ethi nakwi-30-core Coffee Lake Refresh "idla" ukuya kuthi ga kwi-174% yendawo ye-XNUMX mm. ikristale. Ngamanye amazwi, umlinganiselo onjalo unokwandisa isivuno seemveliso ezifanelekileyo kwaye unciphise ngokunzulu inkunkuma.
Nangona kunjalo, ukuba kwi-Intel intsingiselo yokukhulula i-F-series processors ibonakala ngokucacileyo, ngoko ke ukuba abathengi bayaxhamla kwimbonakalo yokunikezelwa okunjalo ngumba ophikisana kakhulu. Amaqhinga akhethwe ngumvelisi anjalo kangangokuba iiprosesa ezikhutshiweyo zithengiswa ngaphandle kwesaphulelo, ngexabiso elifanayo njengabalingane babo "abapheleleyo". Ukuqonda le meko ngokweenkcukacha, sagqiba ekubeni sivavanye omnye wabameli besizukulwana sesithoba seCore lineup, engenazo iigraphics ezakhelwe ngaphakathi, kwaye sizame ukukhangela inzuzo efihliweyo.
I-Core i5-9400F, i-junior six-core processor yesizukulwana seCoffee Lake Refresh, yakhethwa njengento yokufunda. Kukho umdla okhethekileyo kule chip: owandulelayo, , yayidume kakhulu ngexesha elinye ngenxa yomlinganiselo wayo onomtsalane wokusebenza kwexabiso.

Ukuba uvala amehlo akho ekunqongophelweni kwe-GPU eyakhelwe-ngaphakathi, inokuthathwa njengenguqu ehlaziyiweyo ye-Core i3-8350K, ethe yakhawuleziswa ngokongeza iteknoloji ye-Turbo Boost 2.0 kunye nekhono elitsha lokugqithisa ngokuzenzekelayo kwi-4,6 GHz.
Enye imveliso entsha engaphezulu okanye engaphantsi ngokupheleleyo kwiliza lesibini inokuqwalaselwa njengeCore i5-9400 kunye nomntakwabo Core i9-9400F, engenazo iigraphics ezakhelwe ngaphakathi. Ixabiso lale mifuziselo lilele kwinto yokuba ngoncedo lwayo, i-Intel yanciphisa kakhulu iindleko ze-Coffee Lake Refresh yamancinci amathandathu, ivumela ukusetyenziswa kwesizukulwana samva nje see-CPU kuqwalaselo lwenqanaba lesiseko. Nangona kunjalo, akukho mahluko amaninzi asemthethweni phakathi kweCore i5-9400 kunye nokubetha konyaka ophelileyo, iCore i5-8400. Iifrikhwensi zewotshi zonyuka kuphela nge-100 MHz, eyona nto inokwenzeka ngenxa yomnqweno wesigebenga se-microprocessor ukugcina iiprosesa zayo ezincinci ezingundoqo ezintandathu ngaphakathi kwephakheji ye-thermal engama-65. Ngenxa yoko, umsantsa kubuninzi be-turbo frequencies phakathi kwabadala nabancinci abaqhubeki be-core ezintandathu kusapho lweCoffee Lake Refresh yonyuke ukuya kuma-500 MHz, ngelixa kwisizukulwana seCoffee Lake yayingama-300 MHz kuphela.
Ngokusekwe kwiinkcukacha, umntu ufumana imvakalelo yokuba akukho nto ikhethekileyo yokuxina iCore i5-9400 entsha kunye neCore i5-9400F ngokuchasene neCore i5-8400 yakudala. Nangona kunjalo, iinkcukacha kule meko aziniki umfanekiso opheleleyo. Ngexesha lokubhengezwa kweLake Lake Refresh yokuqala, i-Intel yathetha ngeenzuzo ezingathanga ngqo. Ngokomzekelo, kwisizukulwana esitsha se-chips, utshintsho kwi-interface yangaphakathi ye-thermal yathenjiswa: indawo ye-polymer thermal paste yayiza kuthathwa yi-solder esebenza kakuhle kakhulu. Kodwa ngaba oku kunento yokwenza nabancinci besizukulwana sesithandathu abaqhubekisi beCore? Kuvela ukuba ayisoloko.
Iinkcukacha malunga Core i5-9400F
Kwenzeka njalo ukuba xa ukhulula iiprosesa zeCoffee Lake Refresh, i-Intel yadibanisa iinketho ezininzi ezahlukeneyo zeekristale ze-semiconductor ngeteknoloji yenkqubo ye-14++ nm, kwaye ayizizo zonke zintsha. Iiprosesa ze-Core zesizukulwana sesithoba zinokusekwa kuzo zombini iikristale zesemiconductor ezenzelwe zona ngokukodwa, kunye neenguqulelo zakudala zesilicon, ezathi zasetyenziswa ngenkuthalo, kubandakanywa nabaqhubekeki besizukulwana sesibhozo, abahlelwa njengosapho lweCoffee Lake.
Ngokukodwa, okwangoku iyaziwa malunga nobukho beekristale ezine zokunyathela ezifakwe kwiiprosesa ezithile zeCore eziveliswe ngobunzima ezinamanani asuka kuthotho lwamawaka alithoba:
- I-P0 kuphela kwenguqulelo "enyanisekileyo" yekristale namhlanje, enokuthiwa ngenene iCoffee Lake Refresh. Le crystal inee-cores ezisibhozo ze-computing kwaye isetyenziselwa i-overclocking processors Core i9-9900K, i-Core i7-9700K kunye ne-Core i5-9600K, kwii-F-variations zabo Core i9-9900KF, i-Core i7-9700KF kunye ne-Core i5-9600KF, kunye kwiprosesa Core i5-9400;
- I-U0 yikristale engundoqo emithandathu, eyayisetyenziswa ngaphambili kwiiprosesa zeCoffee Lake, oko kukuthi, kwisizukulwana sesibhozo i-Core. Ngoku isetyenziselwa ukwenza i-core Core i5-9400F;
- I-B0 yi-quad-core chip esetyenziselwa i-Core i3-9350K iprosesa. Le nguqulo ye-silicon nayo yeza ngqo kwi-quad-core Coffee Lake processors, kubandakanywa ne-Core i3-8350K;
- I-R0 kukunyathela kwetshiphu entsha apho kulindeleke ukuba iiprosesa zeCore zesizukulwana sesithoba zidluliselwe, ukuqala ngoMeyi. Okwangoku, ayifumaneki kwii-CPU ze-serial, kwaye ke akukho lwazi luthile malunga neempawu zayo kunye nezizathu zokubonakala kwayo.
Ke, i-Core i5-9400F, esithetha ngayo kolu hlaziyo, yigusha emnyama: iprosesa eyodwa-eyohlukileyo eyahlukileyo kwisakhiwo sangaphakathi ukusuka kwabanye abazalwana abathandathu abaphambili kunye nabasibhozo. isizukulwana Coffee Lake Refresh. Ukuthetha ngokuthe ngqo, ayisiyiyo inguqulelo ehluthiweyo okanye ecothayo ye-Core i5-9600K okanye i-Core i5-9400, kodwa inguqulelo encinci ye-Core i5-8400 yakudala enegraphics core ekhubazekileyo.
Kwaye kufuneka nditsho, oku kubonakaliswa kungekuphela nje kwii-screenshots zezixhobo zokuxilonga, eziza kubonisa i-U5 endala endaweni ye-P9400 entsha ye-Core i0-0F. I-Core i5-9400F ayinayo ngokwenene nayiphi na into entsha yeCoffee Lake Refresh kwaphela. Ngokukodwa, xa udibanisa ezi chips, ikristale ayithengiswanga kwisigqubuthelo sokusasazwa kobushushu, kwaye ujongano lwangaphakathi lwe-thermal lufana ngqo ne-polymer thermal paste eyayisetyenziswa kwiiprosesa zeCoffee Lake.
Ukongeza, i-Core i5-9400F, ngokungafaniyo nezinye iiprosesa zesizukulwana seCoffee Lake Refresh, idityaniswe kwibhodi yesekethe eprintiweyo enePCB ebhityileyo - efanayo naleyo isetyenziselwa iCoffee Lake eqhelekileyo.
Ngaphezu koko, kwanemilo yesigqubuthelo sokusasazwa kobushushu beCore i5-9400F ityhila ubudlelwane bale prosesa kunye nesizukulwana sesibhozo iCore. Emva kwayo yonke loo nto, iqweqwe leCoffee Lake Refresh litshintshile.
Ngamanye amazwi, akukho mathandabuzo ukuba i-Core i5-9400F eneneni ayisiyiyo iCoffee Lake Refresh, kodwa ukwaliwa kwenkqubo yesizukulwana sangaphambili esinondoqo wegraphics okhubazekileyo. Ngaphezu koko, oku kusebenza kwi-5% yazo zonke ii-serial ezibonelelwe ngoku i-Core i9400-5F, echaza ubukhulu becala ukufumaneka okubanzi kwezi processors ngexesha apho iingxaki eziphawulekayo ziqhubeka nokubonwa ngobonelelo oluninzi lwezinye i-Coffee Lake Refresh. Ngokomzekelo, umzalwana wakhe "ogcweleyo" kunye ne-UHD Graphics 9400 edibeneyo, echazwe ngokusemthethweni ngaxeshanye kunye ne-Core i630-0F, emele isekelwe kwi-crystal "enyanisekileyo" ye-PXNUMX yokunyathela, ayifumaneki ukuthengiswa kweentengiso.
Ngelo xesha, i-microprocessor giant ayibandakanyi ithuba lokudlulisela i-Core i5-9400F kwi-P0 "echanekileyo" yokunyathela kwixesha eliphakathi. Kodwa oku kuya kwenzeka, ngokucacileyo, kuphela xa zonke iinkampani zeCoffee Lake ezineziphene ezakhelwe ngaphakathi GPU eziqokelelwe kwiindawo zokugcina iimpahla zenkampani zithengiswe ngempumelelo.
Nangona kunjalo, kubasebenzisi abaninzi le nyani yokukhohlisa iikristale zesilicon ayinakwenzeka ukuba ibenantsingiselo. Kungakhathaliseki ukuba kunjalo, i-Core i5-9400F iyinyani ye-core core processors ngaphandle kwe-Hyper-Threading inkxaso, eqhuba i-100 MHz ngokukhawuleza kunokwandulelayo, i-Core i5-8400, phantsi kwayo nayiphi na imithwalo. Oku kuthetha ukuba ngokwefomula ye-frequency, i-Core i5-9400F ihambelana ne-$ 10 ebiza kakhulu i-Core i5-8500.
Ngaphandle kwento yokuba i-Core i5-9400F ibanga isiseko esisezantsi se-2,9 GHz, eneneni le prosesa iyakwazi ukusebenza ngokukhawuleza kakhulu ngenxa yetekhnoloji yeTurbo Boost 2.0. Nge-Multi-Core Enhancements enikwe amandla (oko kukuthi, kwimowudi engagqibekanga kuninzi lweebhodi zoomama), kumthwalo opheleleyo i-Core i5-9400F iyakwazi ukugcina i-frequency ye-3,9 GHz, ikhawuleza ukuya kwi-4,1 GHz phantsi komthwalo omnye-core.
| Ilinganiswe rhoqo | Ubuninzi befrikhwensi yeTurbo Boost 2.0 | ||||||
| 1 undoqo | 2 iicores | 3 iicores | 4 iicores | 5 amanqaku | 6 amanqaku | ||
| I-i5-8400 | 2,8 GHz | 4,0 GHz | 3,9 GHz | 3,9 GHz | 3,9 GHz | 3,8 GHz | 3,8 GHz |
