Yini clocked

Ngokwembali, isantya iwotshi CPU isalathisi ephambili yokusebenza ikhompyutha, yaye ngaxesha lithile nokuba umntu abangafundanga ongazaziyo woqondo disc into eyahlukileyo ukusuka bhetyebhetye, ukwazi ukuchaza ukuba ngokuqinisekileyo ukuba gigahertz ngakumbi kulo imoto, ukuba ngcono, akukho muntu Ndamphikisa naye. Namhlanje, phakathi kwexesha computer, olu hlobo fashion sele idlule, kwaye ababhekisi zizama ukubaleka ngakwicala yokudala lwezakhiwo ugqibeleleyo, ukwandisa inani cache kunye nenani umphakathi, kodwa rhoqo iwotshi i "ukumkanikazi" ukusebenza. Okuqhelekileyo, oku inani imisebenzi nezakhiwo (imijikelo) ukuba kumqhubekekisi unokwenza okwesibini.

Oku kulandela ukuba xa ephezulu amaza clock CPU, imisebenzi eziziziqalelo ngakumbi kukwazi ukuphumeza i khompyutha, yaye ngenxa yoko, ngokukhawuleza esebenza.

Le wotshi rhoqo iziqhubekisi eliphezulu isusela ukusuka ezimbini ukuya gigahertz ezine. Ixhomekeka phinda ibhasi frequency iprosesa kwindawo ratio ethile. Umzekelo, Intel odolo enguNdoqo i7 isebenzisa x20 wokuphindaphinda kunye rhoqo ibhasi lingana 133 MHz, apho rhoqo iwotshi wegama 2660 MHz.

iziqhubekisi Modern: cache kernel

Nangona into yokuba ngaphambili i "multi-core" yaba ezintsha kwimarike namhlanje abatshatanga-core phantse akukho esixhasiweyo. Kwaye akukho nto ayimangalisi kulo, ngokuba ishishini kwikhompyutha bemi ngxi.

Ngako oko ke kucace gca ukuba ukujonga frequency iwotshi njani kumqhubekekisi, ukuba nuclei ezimbini okanye ngaphezulu.

Kuthiwa kukho ukungaqondi eqhelekileyo malunga ekubaleni nezihlandlo iziqhubekisi ezinjalo. Umzekelo: "Kukho kumqhubekekisi mbini-core clocked kwi 1.8 GHz, yiyo rhoqo ogcweleyo uya kuba 2 x 1.8 GHz = 3.6GGts, andithi?". Hayi, engalunganga. Ngelishwa, inani umphakathi ayichaphazeli iwotshi lokugqibela kukwazi ukuba iprosesa wakho ukusebenza ngesantya-3 GHz, ngoko oko kuyasebenza kwaye iya kuba, kodwa kukho inani elikhulu umphakathi ukwandisa izibonelelo zawo, kwaye loo nto, ukwandisa kakhulu ukusebenza.

Musa ukulibala ukuba umqhubekekisi mihla ingakumbi mali obalulekileyo efihlakeleyo memory. Le khompyutha memory wakuzila, nto leyo kuphindwa kwi ulwazi msebenzi, nto leyo efunekayo ukufikelela ngokukhawuleza ngexesha elinikiweyo.

Ekubeni olu hlobo imemori lubiza kakhulu kwaye onzima ukuvelisa, ixabiso layo lincinane noko, kodwa ke ozilingeneyo ezo parameters ukuze kwandiswe ukusebenza kwale nkqubo ngaphandle kokutshintsha iparameters ezifana wotshi frequency.

isantya sewotshi CPU obukhulu kunye lunikezelo

wayeza computer yakho kusenokwenzeka ukuba waba okulungileyo, ngenye imini lo gama lixesha. Kodwa musani ukuphatha nto kulo doti, kunye isipaji evulekileyo lokubalekela Kwivenkile ye-elektroniki elikufutshane. Ezininzi iziqhubekisi zale mihla ikhadi levidiyo ibonelela ukukhawulezisa ezongezelelweyo (ukongeza kwi mveliso), yaye nokuba injini elungileyo, ungenza anyuse umgangatho eliyimali njalo 200-300 GHz. Kuba bamazwe kunye nabathandi amanani amakhulu kukho kwakhona i "overclocking" ubizo ukutyhudisa ngaphandle ubugcisa ubuninzi. Abantu abaninzi ababandakanyeka kulo ishishini esiyingozi, ngokulula overclock i core kumqhubekekisi olunye ukuya ku 6-7 GHz, abanye bade wabeka yokusebenza ingxelo 8.2 GHz band.
