ATI ukungaphumeleli ezihambisana bokwakha oxutyiweyo, esasisetyenziswa imifanekiso abadala. A umoya umoya, ibiya kubonakala, iye yazisa isisombululo esitsha ngohlobo ATI Radeon HD 3800. Kwathi kamsinya nje iimali siqinise baye banda kwaye indima yayo kwimarike yase 3D-accelerators. Noko ke, ukuba ukubetha ekhuphisana yayo ephambili, ababa nako. Isizathu kukuba ATI likhuphe chip nge bug fixes, kodwa akukho ngaphezulu.

Kwandula ke kwabakho ezilungileyo Radeon HD 3870 X2, apho wada waba yinkokeli kwi icandelo amakhadi enamandla yevidiyo, kodwa wahlala ixesha elide. Kwacaca ukuba sihlole izinto zenkampani bazisebenzise bazigqiba iitalente zabo. Usindiso kuba ATI Radeon HD 4800 kuye kwaba, endiwenziweyo ngexesha eninzi ingxolo.

izixhobo Packaging

Le Radeon HD 4800 Series waqalisa ukuba ziveliswe phantsi igama lebrendi Power Umbala Company, leyo kukade icangcisiwe, ummeli we ATI. Ukuhanjiswa kwaqala kwibhokisi encinci yokuzonwabisa nkqo ezenziwe ikhadibhodi. Kwicala ngaphambili kukho umfanekiso enemibala, kunye neempawu eziphambili imodeli. Ekuqaleni, lo HD Radeon 4800 yaye kubekwe njengesisombululo wokudlala, njengoko kuboniswa isilogeni kwi bhokisi. Noko ke, amava ukusuka yahonjiswa kudlula ngokukhawuleza. Enyanisweni, le nkampani azafakwa iphakheji into entsha eza kulahlula esihlweleni. Abasebenzisi sele kunokuba kwelifu umfanekiso robots, izilo, kunye nabanye abasebenzi etsomo.

Iqela Radeon HD 4800 Kuyinto eqhelekileyo ukuba olu hlobo iimveliso. Ukuqalisa, awuna nantoni ukuyithenga kakhulu, kodwa endaweni bekukho izidanga entle, ezifana umdlalo okanye software. Yiba ukuba kunjalo, izixhobo kunye bhokisi kwenza bahle.

iimpawu

Into yokuqala, kubalulekile ukuqaphela ukuba ikhadi vidiyo isebenzisa uhlobo kunokuba endala yinkumbulo - GDDR3. Kakade ke, oku kubhekiselele iziphene zayo, kodwa kusenokwenzeka ukuba ngokukodwa inzuzo ebalulekileyo omnye - ixabiso. Ngenxa uhlobo khadi umsebenzisi kuxabisa dollar nje kwama-200.

Ababhekisi phambili baye bakwazi ukwenza imodeli elungileyo ukuba uyakwazi ukubeka ukhuphiswano Nvidia GeForce 9800 GTX. Kulo mzekelo, sime ubungakanani compact ngakumbi. Abasebenzisi abaninzi nokuba bamangaliswe kukuba kwisixhobo omncinane unawo amandla.

VRAM le Radeon HD 4800 abangama-512 MB, ethi namhla ibekho ubuncinane kuyimfuneko. Nangona umthamo yayo encinane, ikhadi ubonisa ukusebenza kakuhle. Oku kwenziwa kwenzeka ngenxa ukusetyenziswa ngokuyimpumelelo kwazo memory chip.

injini

Eyenziwa yi uhlobo inkqubo ifumaneka kwi Radeon 3800 series. Ayaziwa indlela ababhekisi saphumeza ukupholisa, ngokuba kuthotho ngaphezu 4.800 umbane kakhulu. Ngoko ke, kusenokubakho nobushushu.

Isixokelelwano sokupholisa yi kwesibandisi kunye nenani elikhulu iincakuba, kunye radiator ezihlaziyiweyo. Yenziwe konke a slot enye. Uyilo kusenokubonakala ngathi lubhedu, kodwa eneneni evela kwenye intsila: Ukuze ubone oku, ekuqaleni nokwaleka ngokwaneleyo. Le radiator ibandla evela amacwecwe amancinane, ekufuneka athathe 110 W ubushushu. Fan wavuka iincakuba-19, nto leyo eyandisa nocikizeko nomsebenzi wayo. Le nkqubo isebenza kakhulu ingxolo. Noko ke, ngenxa isandi namanye amacandelo computer, kwamkelekile.
