Indlela ukukhetha kumqhubekekisi yokudlala

Abaninzi isankenteza iinkumbulo odumileyo "megahertz Uhlanga", apho abenzi eziphambili CPUs ugxininiso zonke ishishini elitsha imodeli kwi- frequency koloko. Kule meko, singasathethi iteknoloji edume Intel ekuthiwa Burst Net. Nangona izixhobo ezinjalo lula ukoyisa bha GHz 4 (yemigangatho zobugcisa xesha yaba impumelelo) kunye, ngokulandelelana, kubekwe iziqhubekisi imidlalo, ukuba wawusele-inyaniso. Nangona, xa kuphela ngenxa yokuba ukwandisa frequency eziyimfuneko ukwandisa ubude swa. Ngenxa yoko ibinzana elithi "megahertz umngxuma" - phinda ophezulu kunye nokusebenza laliphakathi nje.

Emva kwaye kwacaca ukuba le ndlela ezingenakuphela yi ukunyusa isantya msebenzi kwahluka ngokupheleleyo ingqiqo yaphakanyiswa. It kukwandisa inani umphakathi. Xa ukhetha njengomqhubekisi imidlalo, kufuneka ukhumbule oku. Oko kukuthi, umqhubekekisi multi-core yinto iiyunithi computing ngakumbi ngokupheleleyo-epheleleyo incoko, kodwa obekwe kwi zeendawana chip enye. Kakade ke, kukho kuncanyatheliswe onjalo wenza eminye hardware kunye software noun. Okwangoku, le ulwalathiso equlunqiweyo ngononophelo, yaye oko kufanele ingqalelo.

Ukukhetha iprosesa ye imidlalo. Iinkozo

Ngoko ke, Ebeka i ngasentla, senza isigqibo lokuqala: omnye iimpawu eziphambili ezichaphazela intsebenzo linani umphakathi. iziqhubekisi ezininzi imidlalo iqulethe umphakathi 6. Imizekelo iquka i-Intel Core i7-980X yaye FX-6200 evela AMD. Ilindele counter-mibuzo, xa siphawula ukuba nangona ingezizo zonke imidlalo bazisebenzise ngokupheleleyo eziliqela umphakathi, le meko neziguquka ngokukhawuleza. Kubalulekile ukukhumbula inguqu ukusuka kwelinye ukuya yemifanekiso dvuyahdernym xa wathi inzuzo kwicala eliphezulu-rhoqo kwi iziqhubekisi engundoqo enye.

Transmission yedijithali umsinga data phakathi izixhobo lwenziwa ngokugqitha kwinkqubo ibhasi. Intel lo QPI, yaye AMD - Hyper Transport. Emva kokuba waqala ukuba zibekwe phakathi chip engundoqo izilawuli ezininzi, le kaloliwe-high speed yayisetyenziswa kuphela kunxibelelwano lwangaphakathi. Ngenxa yoko, iprosesa kakuhle imidlalo kufuneka babe aqhelelkileyo isondo. Olu phawu isoloko kubalulwe imigaqo kwefowuni. Ngokomzekelo, wathi Core i7 980X QPI nebhasi ngomthamo 6.4 GT / s, kwaye Pentium lwabiwo 620 - iyonke 4.8 GT / s.

cache

iprosesa Good yokudlala kufuneka imali eyaneleyo efihlakeleyo memory. Kwizigqibo zanamhlanje iye abaninzi kangangoko imiphakamo emithathu - L1-L3. Ngaphezu ubungakanani babo amakhulu, ngcono. Elinemveliso ngakumbi ukuba lo imemori kubalulekile ukusebenza echanileyo chip multi-core, kuchaphazela kakhulu ukusebenza.

zokufudumeza

Xa ukhetha omtsha umqhubekekisi wokudlala, maxa wambi silahlekelwe ngokupheleleyo phambi kwale parameter, njengoko ubushushu. Bafumana, kuba ngamanye amaxesha kuyenzeka ukuba athenge isisombululo kunye umgangatho ofanayo komsebenzi, lo gama idla amandla ngaphantsi. Kuyanconywa ukuba ukhethe imodeli eyongayo ngakumbi: ukuba yehliswe nje kuphela i-akhawunti ukuba ahlawule kilowatt bagqitywe, kodwa ukuzola inkqubo sokupholisa.
