Ukukhishwa okusemthethweni kwekhadi lehluzo le-NVIDIA GeForce RTX 4090 kuphinde kwavusa ukuthengwa okuningi ngabadlali abaningi. Nakuba intengo iphezulu njenge-12,999 yuan, isathengiswa ngemizuzwana. Akukhona nje kuphela ukuthi ayithinteki ngokuphelele ukwehla kwamanje kwamanani ekhadi lehluzo, kodwa isemakethe yesibili. Kube nokwanda kokuthengiswa kwi-inthanethi, futhi ngempela "kuyiphupho lokubuyela esicongweni" ngokwentengo.
Isizathu sokuthi ikhadi lehluzo le-RTX 4090 lingaletha ithonya elikhulu kangaka ezingeni lezinto ezingavamile akusona nje isihloko sekhadi lehluzo lokuqala ochungechungeni lwe-RTX40, kodwa futhi nokusebenza okudlula kakhulu ikhadi lehluzo lesizukulwane esidlule i-RTX 3090Ti yisona sizathu esibaluleke kakhulu, eminye imidlalo "ebulala amakhadi ehluzo" ingafinyelela nokusebenza okuphelele kusisombululo se-4K. Ngakho-ke, hlobo luni lwesikrini olungasebenzisa ngempela i-RTX 4090?
1.I-4K 144Hz iyisimo esibalulekile
Ukuze sisebenze kahle kakhulu ikhadi lehluzo le-RTX 4090, silinganise imisebenzi eminingi edumile ye-3A ekuhlolweni kwamakhadi wehluzo kwangaphambilini. Ngokusho kwedatha yokuhlola umdlalo, ikhadi lehluzo le-RTX 4090 lingafinyelela umphumela wesithombe ongu-133FPS ngesinqumo esingu-4K se-"Forza Motorsport: Horizon 5". Uma kuqhathaniswa, i-RTX 3090 Ti ehamba phambili yesizukulwane sangaphambilini ingakhipha izithombe ezingu-85FPS kuphela ngesinqumo esingu-4K, kuyilapho izinga lohlaka lwe-RTX 3090 liphansi nakakhulu.
2. Ngakolunye uhlangothi, ikhadi lehluzo le-RTX 4090 liphinde lengeza ubuchwepheshe obusha be-DLSS3, okungakhuphula kakhulu izinga lohlaka lokukhipha ikhadi lehluzo, futhi iqembu lokuqala lemidlalo engu-35 esekela imisebenzi ye-DLSS3 seliqalisiwe. Ekuhlolweni kwe-"Cyberpunk 2077", inani lamafreyimu lenyuke laya ku-127.8FPS ngemuva kokuthi i-DLSS3 ivuliwe ngesisombululo se-4K. Uma kuqhathaniswa ne-DLSS2, ukuthuthuka kokuguquguquka kwesithombe kwakusobala kakhulu.
3. Njengomthwali obalulekile wokukhipha izithombe zamakhadi ehluzo,ngenkathi ukusebenza kwe-RTX 4090 kuthuthukisiwe, futhi kubeka phambili izidingo eziphezulu zokusebenza kweziqaphi zemidlalo. Ngokuphathelene nesisombululo, ikhadi lehluzo le-RTX 4090 lingakhipha izithombe ze-HDR ezifika ku-8K 60Hz, kodwa izibonisi zesisombululo se-8K zamanje emakethe azivamile nje kuphela, kodwa intengo yamashumi ezinkulungwane zama-yuan ayinobungane. Ngakho-ke, kubadlali abaningi, isibonisi sesisombululo se-4K siseyisinqumo esifaneleka kakhulu.
 
Ngaphezu kwalokho, kungabonakala futhi kudatha yokuhlola ye-RTX 4090 ukuthi inani lamafreyimu omdlalo ajwayelekile lidlule i-120FPS ngemuva kokuthi i-DLSS3 ivuliwe. Ngakho-ke, uma izinga lokuvuselela lesibonisi lingakwazi ukuhlangabezana nezidingo zekhadi lehluzo, isikrini singase sidabuke ngesikhathi somdlalo. , yize ukuvula ukuvumelanisa okuqondile kungaxazulula inkinga, kodwa kuchitha kakhulu ukusebenza kwekhadi lehluzo. Ngakho-ke, izinga lokuvuselela liyisilinganiso sokusebenza esibaluleke ngokulinganayo sabaqaphi bemidlalo.
4. I-HDR esezingeni eliphezulu kufanele futhi ibe ejwayelekile
Kubadlali be-AAA, ikhwalithi yesithombe ibaluleke kakhulu kunesivinini sokuphendula esiphezulu. Imisebenzi yobuciko ye-3A yanamuhla isekela izithombe ze-HDR, ikakhulukazi uma ihlanganiswa nemiphumela yokulandelela imisebe, inganikeza ukusebenza kwekhwalithi yesithombe okufana nomhlaba wangempela. Ngakho-ke, ikhono le-HDR libalulekile nakuma-monitor emidlalo.
5. Naka inguqulo yesibonisi
Ngaphezu kokusebenza kanye ne-HDR, uma ufuna ukusebenza okuhle kakhulu kwekhadi lehluzo le-RTX 4090, udinga futhi ukunaka ukukhethwa kwenguqulo yesibonisi sokubonisa. Njengoba ikhadi lehluzo le-RTX 4090 lifakwe izixhumi zokukhipha zenguqulo ye-HDMI2.1 kanye ne-DP1.4a. Phakathi kwazo, i-bandwidth ephezulu yesibonisi se-HDMI2.1 ingafinyelela ku-48Gbps, engasekela ukudluliselwa kwegazi okugcwele ngaphansi kwekhwalithi yesithombe enencazelo ephezulu ye-4K. I-bandwidth ephezulu ye-DP1.4a ingu-32.4Gbps, futhi isekela nokukhipha isikrini sokubonisa esifinyelela ku-8K 60Hz. Lokhu kudinga ukuthi i-monitor ibe nesibonisi sevidiyo esifanayo esisezingeni eliphezulu ukuze ikwazi ukukhipha isignali yesithombe ngekhadi lehluzo.
 
Ngamafuphi, kubangani abathenge noma abahlela ukuthenga ikhadi lehluzo le-RTX4090. Ukuze uthole ukusebenza kwekhwalithi yesithombe okungcono kakhulu, ngaphezu kokuhlangabezana nokusebenza okuphambili kwe-4K 144Hz, umphumela we-HDR kanye nokusebenza kombala nakho kuyizinto ezibalulekile okufanele uzicabangele.
