Video memory. amakhadi Ushwankathelo: inkokheli ukusebenza

Ngexesha apho ulwazi nobugcisa liye langena phantse kuzo zonke iinkalo zobomi, ngokuya kakhulu kuthandwa kunye nekhompyutha imidlalo. Umsebenzisi avareji akuthethi ingakumbi ucinge ngeenkcukacha nePC yakho, kodwa nabadlala zisoloko ndikhangele ukuba amacandelo enamandla kakhulu kangangoko kunokwenzeka. Enye yezona ndawo ziphambili ikhadi imizobo, yaye abathandi yokudlala ukuba isoloko ikhangela iindlela ukwandisa isixa yevidiyo memory.

Eyona engundoqo Ipharamitha amakhadi

Yintoni, enyanisweni, kubalulekile ukuba ikhadi yemizobo PC mihla? Okokuqala, eyikhethayo isantya intshukumo bomfanekiso kwikhusi. Elijongene nalo msebenzi we amandla GPU. Okwesibini, inxalenye iyakwazi ukuxhasa imidlalo yakutshanje. Shader, okanye, ngendlela elula, firmware lubonisa sihambe kunye neemephu mihla.

Kwakhona kakhulu ebalulekileyo iparameters ukusebenza kunye nesantya sokufunda. Ezi zinto zichaphazela isixa yevidiyo kwimemori esetyenzisiweyo. Kukho a caveat: abenzi badla abanganyanisekanga ucacise kwi parameters wemephu kakhulu eninzi inkumbulo, ngokwenjenjalo nokutsalela abathengi. Kodwa enyanisweni la manani abhekisele isixa yokugcina lwasekuhlaleni, nto leyo inoxanduva ixabiso lwedata kusingathwa ngaxeshanye. Noko ke, ngeqondo isakhelo eliphantsi, eli xabiso awungeni ndawo ngokupheleleyo.

Ukukwazi ukugqithisa ulwazi mali elifutshane ixesha kuluphawu data ibhasi. parameters zayo kuluhlu ukusuka amasuntswana 32 ukuya 512.

Ukuze kwandiswe inani igalelo esweni yaye kuphucula imveliso usebenzisa ubuchwepheshe yokuseka amakhadi amabini ngaxeshanye. Le nkqubo igama SLI kunye crossfire. Izihlanganisi (VGA, DVI, okanye uqhagamshelwano lwetshiphu emsebenzi) aluchaphazeli ukusebenza imidlalo.

Ikhadi yemizobo ezinamandla ngakumbi, ubushushu namandla likhipha. Ngoko ke, kufuneka sinikele ingqalelo umgangatho iinxalenye inkqubo sokupholisa. Ukuba ikhadi ebilayo rhoqo, umfanekiso yekhusi igqwethekile, yaye ngenene umba ngokukhawuleza asilele.

Yintoni na le mali ubuncinane yevidiyo memory kufuneka nendlela ukuba kunye nezinye iparameters? Ngokubanzi, iingcali bacebisa ukuba ukhethe ikhadi yemizobo ngamandla computer.

Volume "for Dummies" VRAM
