Yiyiphi ikhadi levidiyo ekukhethiweyo kumdlalo

Amathuba omdlalo ngamnye ngonyaka, ewe apho, inyanga nganye ikhula, ivelise iinjine ezintsha kunye nazo zonke iintlobo zeenguqulelo. Ubuchwepheshe be-DirectX buya kuba nzima nakakhulu. Imidlalo ineemfuno eziphambili zeenkqubo. Kwaye oku kulungile kwaye kunengqiqo. Akukho nto imele, yonke into ingatshintsha kwaye iphuculwe. Konke oku kusekelwe ngokukodwa kwizidingo zabantu. Eli nqaku lizinikezelwe kwikhadi levidiyo ukuba likhethele imidlalo, kunye neyiphi iipameters oyifunayo ukwenza lo khetho.

Criteria

Okokuqala, machaze iiparameters ezisiseko zesixhobo. Indlela yokukhetha ikharityhulam yevidiyo elungileyo, unokuxelela iziganeko zayo:

• Shader version. Oku phezulu (umzekelo, i-4.0), intle kakhulu kwaye ichaneke ngakumbi umfanekiso oza kuba. Iimidlalo zanamhlanje zithatha inqwaba yemivulo yeenguqulelo zakutsha, ngokukhawuleza ukulayisha kwekhadi levidiyo.
• Inkqubo ye-Graphics (GPU). Intliziyo yekhadi levidiyo. Ukusebenza konke kwesi sixhobo kuxhomekeke kuyo. Ephakamileyo ubukhulu beGPU, izakhelo ezingaphezulu ngesibini ziya kukhutshwa xa ziqhuba izicelo zokudlala. Umqathango obaluleke kakhulu wekhadi levidiyo ekuthengeni.
• Imemori ye memori yevidiyo. Ukukhawuleza kunye nokuvelisa okona mzuzu nguGDDR5. Iinguqu ezindala (i-GDDR4, 3, 2) ayivelisi ngaphantsi.
• Inani lememori yevidiyo. Isibonakaliso esibaluleke kakhulu ukuba umboniso omkhulu (22-23 intshi) uyongezwa kwisixhobo . Eyona nkulu i-monitor, imemori khadi ikhamera yevidiyo iya kufuneka ivelise umfanekiso ophezulu ngaphandle kokuphazamiseka.
• DirectX. Iphuzu elibaluleke kakhulu xa uphendula umbuzo malunga neyiphi ikhadi levidiyo ekukhethiweyo kumdlalo, kuba akukho onke amacebo alolu hlobo axhasayo inguqu yakutshanje ye-DirectX 11. Kodwa kwiplani enjalo ukuba zonke iiprojekthi zemidlalo emitsha kunye nezobugcisa zikhishwa.
• Inkxaso ye-Crossfire okanye i-SLI. Ngokuxhomekeka kohlobo lomenzi, ifowuni inokuxhasa umsebenzi wokudibanisa i-adapters ezininzi zevidiyo ukuze ufumane umsebenzi ophezulu kwi-duet (triplet). Kule meko, kufuneka uqaphele ngokunyanisekileyo ukupholisa nokuphuphuma umoya kwunithi yenkqubo.
• Ubungakanani besondo. Ngokuqhelekileyo, eli phezulu, lo mveliso uza kuba yi-adapter yevidiyo. Eyona ndlela ikhethekileyo yikhadi levidiyo elinama-256 bits.

Nvidia okanye ATi Radeon

Kwimakethi yekhadi levidiyo, ezimbini zeenkampani ezinkulu zikhuphisana: ATI noNvidia. Ukuba umthengi unemibuzo malunga neyiphi ikhadi levidiyo ekukhethiweyo kwimidlalo, ukuphindwa kabini kwimbono kuvela ngokungenakuzibandakanya: umntu ufuna ukuthenga indalo yeNvidia, ngoxa uRadeon enjalo. Kubalulekile ukukhankanya ukuba zombini iinkampani zivelisi zokusebenza eziphezulu kunye nezixhobo zokusebenza. Ngoko ke, ukukhethwa kwenkampani yedwa. Nangona kunjalo, umnini wekhadi "eliluhlaza" (Nvidia) uya kuthi njalo idivayisi yakhe iyona nto ibhetele, ngelixa umnini "obomvu" (uRadeon) uya kuphakamisa ikhadi lakhe levidiyo kwizulu. Ukuba sithetha ngeemveliso zeNvidia, ngoko siyakwazi ukuqulunqa uluhlu lweebhajethi kunye nolusekupheleni kweemodeli ezifanelekileyo kwimidlalo. Umyinge webala: GeForce GTX560 Ti, GTX660 Ti, GTX760 Ti. Uluhlu oluphezulu: GeForce GTX580, GTX680, GTX780 kunye neTTan Titan. Ukuba sithetha ngo-ATI Radeon, sinokuhlukanisa le mizekelo yamakhadi ehluzo yemidlalo: zonke iinguqulelo ze-7900 ne-7800 uchungechunge, kunye ne-HD 6990 no-6950.

Njengoko ubona, ukhetho lukhulu. Into efunekayo ukuba ukhokelwe yiyiphi ikhadi levidiyo ekukhethiweyo kumanqaku yiimpawu ze-adapter yevidiyo kunye nezakhono zayo.
