Imemori yevidiyo ingenye yezimpawu ezibaluleke kakhulu zekhadi levidiyo. Inethonya elinamandla kakhulu ekusebenzeni okuphelele, ikhwalithi yesithombe esikhishwayo, ukuxazululwa kwayo, futhi ikakhulukazi ekutholweni ngekhadi levidiyo, oyofunda ngalo ngokufunda le ndatshana.

Ithonya lemvamisa yememori yevidiyo
I-RAM ekhethekile eyakhelwe ngaphakathi ekhadini levidiyo ibizwa ngokuthi inkumbulo yevidiyo futhi isifinyezo sayo, ngaphezu kwe-DDR (ukudluliswa kwedatha kabili), iqukethe incwadi G ekuqaleni. Lokhu kwenza kucace ukuthi sikhuluma ngqo nge-GDDR (ukuhanjiswa kwedatha ephindwe kabili), futhi hhayi ngolunye uhlobo lwe-RAM. Le subtype ye-RAM inamaza amafushane aphezulu uma kuqhathaniswa ne-RAM evamile efakwe kunoma iyiphi ikhompyutha yesimanje futhi inikezela ukusebenza okwanele kwe-chip yehluzo lilonke, ilinikeze amandla okusebenza ngamanani amakhulu wedatha adinga ukucutshungulwa futhi aboniswe esikrinini somsebenzisi.
Imem bandwidth
Imvamisa yewashi yememori yevidiyo ithinta ngqo i-bandwidth yayo (i-PSP). Futhi, amanani aphezulu we-PSP kwesinye isikhathi asiza ekufezeni imiphumela engcono ekusebenzeni kwezinhlelo eziningi lapho ukubamba iqhaza noma ukusebenza ngemidwebo ye-3D kudingekile - imidlalo yamakhompiyutha nezinhlelo zokwenza imodeli nokwakha izinto ezinobukhulu obuthathu ziwukufakazela lokhu theisis.

Ububanzi bebhasi lokukhumbula
Imvamisa yewashi yememori yevidiyo nomphumela wayo ekusebenzeni kwekhadi levidiyo lilonke ixhomeke ngqo kwenye, ingxenye engabalulekile kakhulu yama-adaptha wehluzo - ububanzi bebhasi lememori nobuningi bawo. Kuyalandela ukuthi lapho ukhetha i-chip yehluzo ekhompyutheni yakho, kufanele unake lezi zinkomba, ukuze ungadumazeki ezingeni eliphelele lokusebenza komsebenzi wakho noma esiteshini sekhompyutha. Ngendlela yokungakhathali, kulula ukuwela imali yokuthengisa yabathengisi abafake i-4 GB yememori yevidiyo nebhasi le-64 emkhiqizweni omusha wenkampani yabo, okuzodlula kancane futhi ngokungaphumeleli ukunqunyelwa kwedatha yevidiyo enkulu kangaka ngabo.
Kuyadingeka ukugcina ukulingana phakathi kwemvamisa yememori yevidiyo nobubanzi bebhasi yayo. Izinga lesimanjemanje le-GDDR5 likuvumela ukuba wenze imvamisa yokusebenza kwememori yevidiyo izikhathi eziphakeme izikhathi ezi-4 kunokuvama kwayo kwangempela. Akudingeki ukhathazeke ukuthi ngaso sonke isikhathi kufanele ubale ukusebenza ngempumelelo kwekhadi levidiyo ekhanda lakho bese ugcine le ndlela elula yokuphindaphindwa kane engqondweni yakho - umenzi ekuqaleni ukhombisa ukuphindaphindwa, okuwukuthi, imvamisa yangempela yememori khadi yekhadi levidiyo.
Kumakhadi ehluzo ajwayelekile angahloselwe ukubalwa okukhethekile nemisebenzi yesayensi, amabhasi enkumbulo asetshenziswa kusuka ku-64 kuye ku-256 ububanzi. Futhi, ezixazululweni zokudlala eziphezulu, kungahle kube nobubanzi bebhasi elingama-352 bits, kodwa inani lekhadi levidiyo lilodwa lingaba izindleko ze-PC eligcwele eligcwele ukusebenza okuphakathi.
Uma udinga "ipulaki" lesilayidi sekhadi levidiyo kubhodi yokusebenzela ehhovisi nokusombulula imisebenzi yehhovisi ngokukhethekile njengokubhala umbiko eZwini, ukudala itafula ku-Excel (ngemuva kwakho konke, ngisho nokubuka ividiyo enezimpawu ezinjalo kuzoba nzima), khona-ke ungaqiniseka ukuthola isisombululo ngebhasi le-64-bit.
Kunoma yikuphi okunye, udinga ukunaka ibhasi le-128-bit noma i-192, futhi ibhasi lememori le-256-bit lizoba yisisombululo esihle kakhulu nesikhiqizayo. Amakhadi wevidiyo anjalo ingxenye enkulu anokunikezwa okwenele kwememori yevidiyo ngokuvama kwayo okukhulu, kepha futhi kukhona okungabizi okuthe xaxa nge-1 GB yememori, okwenzelwe i-gamer yanamuhla akusenele futhi udinga ukuthi okungenani ube nekhadi le-2 GB lomdlalo onethezekile noma umsebenzi kuhlelo lwe-3D, kodwa lapha ukuze ulandele ngokuphepha umgomo "wokungcono."
Ukubalwa kwe-SRP
Isibonelo, uma unekhadi levidiyo elihlotshiswe ngememori ye-GDDR5 enejubane elisebenza kahle le-1333 MHz (ukuthola imvamisa yememori ye-GDDR5, uzodinga ukuhlukanisa ngempumelelo ngo-4) nangebhasi lememori le-256-bit, lizoshesha ukwedlula ikhadi levidiyo elinemvamisa yememori esebenzayo engu-1600. MHz, kodwa ngebhasi le-128-bit.
Ukubala i-bandwidth yememori bese uthola ukuthi ikhiqizile ividiyo yakho ikhiqiza kahle kangakanani, udinga ukuya kuleli fomula: phindaphinda ububanzi bebhasi lememori ngobuningi bememori futhi uhlukanise inombolo ephumela ngo-8, ngoba kunamabhithi amaningi nge-Byte. Inani eliphumelelayo lizoba inani esilidingayo.
Masibuyele emuva kumakhadi ethu amabili evidiyo asuka kwisibonelo esingenhla abale ukubalwa kwemikhawulokudonsa kwawo: eyokuqala, ikhadi levidiyo elihle kakhulu, kepha ngejubane eliphansi lewashi, izolandela (256 * 1333) / 8 = 42.7 GB ngomzuzwana, nekhadi levidiyo lesibili kuphela i-25,6 GB ngomzuzwana.
Ungafaka futhi uhlelo lweTechPowerUp GPU-Z, olukwazi ukubonisa imininingwane eningiliziwe mayelana ne-chip yehluzo efakwe kwikhompyutha yakho, okubandakanya inani lememori yevidiyo, imvamisa yayo, umthamo webhasi kanye nomkhawulokudonsa.

Isiphetho
Ngokusekelwe olwazini olungenhla, kungaqondakala ukuthi imvamisa yememori yevidiyo nomphumela wayo ekusebenzeni kahle kokusebenza kuncike ngqo kwenye into - ububanzi bememori, abakha ngayo inani lokubalwa kwememori. Ithinta ijubane nenani lemininingwane edluliselwa ekhadini levidiyo. Siyethemba ukuthi le ndatshana ikusize ukuthi ufunde okuthile okusha ngesakhiwo nokusebenza kwe-chip yehluzo futhi yanikeza izimpendulo zemibuzo yakho.
