Tsim los yog hloov tshiab a PC Ua Si Nws tsis yog dab tsi. Muaj ntau ntau yam uas peb yuav tsum tau coj mus rau hauv tus account yog tias peb xav kom muaj lub tshuab ua tau raws li peb xav tau. Piv txwv li, nws yog ib qho tseem ceeb heev rau xaiv cov Daim duab nraaj tsim nyog thiab paub meej VRAM ntau npaum li cas (Video Random Access Memory) yog xav tau.
VRAM, tseem hu ua video nco, yog lub luag haujlwm rau khaws cov teebmeem, textures thiab lwm yam ntaub ntawv pom kev yooj yim kom ntseeg tau duab ua tau zoo y qhov kev ua si zoo tshaj plaws ua tau. Hauv kab lus hauv qab no peb yuav txheeb xyuas tag nrho cov no hauv qhov tob.
VRAM yog dab tsi?
Nyob rau hauv lub graphics card, lub VRAM (hauv lus Mev, "Random Access Graphic Memory") yog ib ntu ntawm kev nco tshwj xeeb rau kev ua thiab khaws cov ntaub ntawv pom. Nws yog qhov txawv ntawm qhov system RAM hauv lub hom phiaj kawg ntawm nws tus qauv tsim: kom muaj peev xwm ua haujlwm siab nrawm nrawm.
VRAM ua hauj lwm raws li ib yam ntawm parallel architecture. Qhov zoo ntawm qhov no yog tias nws tso cai rau peb nkag mus sai dua thiab siv cov ntaub ntawv (uas yog qhov tseem ceeb thaum peb tham txog kev ua si hauv lub sijhawm). Qhov dav bandwidth thiab qis latency ntawm VRAM ua ke los muab peb pab neeg Smooth, lag-dawb graphics kev ua tau zoo. Zoo tagnrho rau kev ua si.
Ua li no, qhov loj dua VRAM ntawm daim npav daim npav, cov ntaub ntawv ntau nws tuaj yeem khaws yam tsis tas yuav mus rau lub hard drive lossis system RAM. Qhov no inevitably txhais rau hauv ib qho kev txhim kho tseem ceeb hauv ntu graphical kev ua tau zoo.
Thaum daim npav daim npav khiav tawm ntawm VRAM, lub kaw lus raug yuam kom ua haujlwm nrog lub ntsiab RAM. Qhov no yog thaum muaj kev pheej hmoo ntawm kev txom nyem tsis xis nyob xws li hais lus tawv ncauj (thaum daim duab "stutters") thiab lub sijhawm thauj khoom ntev dua, thiab lwm yam.
VRAM hom los ntawm kev muaj peev xwm
Muaj ntau hom VRAM. Qhov kev xaiv nyob ntawm qhov xav tau ntawm txhua tus neeg ua si. Cov no yog cov feem ntau siv:
- 2 GB, tsim nyog rau lub teeb heev lossis cov kev ua si qub, uas yog, nrog cov kev xav tau tsawg dua. Txawm li cas los xij, nws yog tus nqi qis uas tsis tiv thaiv kev poob qis ntawm qhov tshwm sim.
- 4 GB, qhia rau 1080p gaming ntawm nruab nrab lossis siab. Tej zaum nws yuav tsis txaus nyob rau hauv cov ntaub ntawv ntawm kev ua si tsis ntev los no uas siv cov ntaub ntawv zoo.
- 6 GB, txaus rau ua si hauv 1080p ntawm qhov chaw siab thiab txawm tias qee lub npe hauv 1440p (2K), uas tam sim no yog qhov kev daws teeb meem nrov tshaj plaws. Nws yog ib qho ntawm cov kev xaiv ntau tshaj plaws.
- 8 GB. Rau 1440p gaming ntawm qhov chaw siab thiab 4K gaming ntawm nruab nrab. Nws ua haujlwm zoo nrog yuav luag txhua qhov kev ua si tam sim no.
- 10-12 GB. Qhov zoo tshaj plaws rau 4K gaming ntawm qhov chaw siab nrog cov teebmeem siab heev, uas xav tau ntau npaum li cas ntawm VRAM vim muaj cov pixels loj.
- 16 GB lossis ntau dua. Ib qho kev xaiv hwm uas tuaj yeem siv dhau ntawm kev ua si, vim nws kuj ua haujlwm xws li kev kho video tshaj lij.
Thaum kawg, tus nqi ntawm VRAM uas tus gamer yuav xav tau ntawm lawv daim npav duab nyob ntawm ntau yam. Qhov tseem ceeb tshaj plaws: kev daws teeb meem ntawm cov kev ua si uas feem ntau ua si thiab lawv cov duab teeb tsa. Raws li txoj cai dav dav, lub peev xwm ntawm 6 GB thiab 8 GB yog txaus rau 1080p lossis 1440p daws teeb meem. Saum toj no cov nuj nqis nws raug nquahu kom xaiv cov duab phaib nrog 10 GB lossis 12 GB ntawm VRAM.
Kuv yuav paub li cas VRAM kuv xav tau?
Qhov no yog lub ntsiab tsis ntseeg ntawm txhua tus gamer, txawm lawv qib. Txhawm rau tso qee qhov teeb meem ntawm qhov teeb meem, ntawm no yog qee qhov tswv yim pab tswv yim Thaum nws los txog rau xaiv tus nqi ntawm VRAM:
- Paub zoo txog qhov yuav tsum tau ua si. Cov kev xav tau VRAM feem ntau yog cov ncauj lus kom ntxaws hauv daim ntawv qhia kev ntawm txhua lub npe.
- Saib ntawm qhov kev daws teeb meem thiab cov duab kos duab. Ua si hauv 1080p koj tsis xav tau ntau dua 6-8 GB ntawm VRAM. Ntawm qhov tod tes, rau 1440p lossis 4K ua si, daim npav nrog 8-12 GB yuav tsim nyog dua.
- Xav txog seb koj puas yuav siv mods txhawm rau txhim kho textures lossis ntxiv cov ntsiab lus pom tshiab, txij li cov xwm txheej no koj yuav xav tau VRAM ntau dua.
- Xav lub sijhawm ntev. Cov kev ua si tshiab uas tshwm sim tau xav tau ntau ntxiv rau peb lub PCs vim li ntawd nws tsim nyog xaiv daim npav nrog VRAM me ntsis siab dua qhov koj xav tau, kom nws tuaj yeem siv tau ntau xyoo.
Qhov kawg tab sis tsis kawg, koj yuav tsum paub nyiaj npaum li cas koj xav tau (lossis tuaj yeem) siv. Qee zaum, nws tsis tas yuav mus rau qhov kev xaiv kim tshaj plaws. Qhov tseem ceeb yog paub tias yuav tsum muaj VRAM ntau npaum li cas.
Txawm li cas los xij, peb yuav tsum nco ntsoov xav txog peb cov kev xav tau tam sim no thiab yav tom ntej txhawm rau txhawm rau Xaiv daim npav zoo tshaj plaws kom txaus siab rau kev ua si puv thiab dej.
