Ukuchazwa Kwamafayela Wezithombe Eziphuthumayo kanye Nemininingwane kwi-AGP vs PCIe ne-PCI
I-Speed Graphics Port, evame ukufinyezwa njenge-AGP, uhlobo olujwayelekile lokuxhumana kwamakhadi wevidiyo angaphakathi.
Ngokuvamile, i-Speed Speed Graphics Port ibhekisela esenzweni sangempela sokwandisa ebhodini le- motherboard elamukela amakhadi wevidiyo we-AGP kanye nezinhlobo zamakhadi wevidiyo ngokwayo.
Ama-Versions we-Portels aphuthumayo
Kunezinto ezintathu ezijwayelekile ze-AGP:
| Isivinini sewashi | I-voltage | Isivinini | Isilinganiso sokudlulisa | |
| I-AGP 1.0 | 66 MHz | 3.3 V | I-1X ne-2X | 266 MB / s kanye no-533 MB / s |
| I-AGP 2.0 | 66 MHz | 1.5 V | 4X | 1,066 MB / s |
| AGP 3.0 | 66 MHz | 0.8 V | 8X | I-2,133 MB / s |
Inani lokudlulisa ngokuyisisekelo liyi- bandwidth , futhi lilinganiselwa kuma- megabytes .
Izinombolo ze-1X, 2X, 4X, ne-8X zibonisa ijubane lokuhamba komkhawulo ngokuphathelene nesivinini se-AGP 1.0 (266 MB / s). Isibonelo, i-AGP 3.0 igijimela ngezikhathi eziyisishiyagalombili ijubane le-AGP 1.0, ngakho-ke ukuphakama kwayo komkhawulokudonsa izikhathi eziyisishiyagalombili (8X) ze-AGP 1.0.
I-Microsoft ibize igama le-AGP 3.5 le- Universal Accelerated Graphics Port (UAGP) , kodwa izinga lokudlulisa, izidingo zamandla, neminye imininingwane ifana ne-AGP 3.0.
Kuyini i-AGP Pro?
I-AGP Pro iyinhlangano yokwandisa eyinde kunayo ye-AGP futhi inezikhonkwane ezingaphezulu, inikeza amandla amaningi ekhadini levidiyo le-AGP.
I-AGP Pro ingaba usizo emisebenzini enamandla kakhulu, njengezinhlelo zehluzo eziphambili kakhulu. Ungafunda kabanzi mayelana ne-AGP Pro ku- AGP Pro Specification [ PDF ].
Umehluko Phakathi kwe-AGP ne-PCI
I-AGP yasungulwa yi-Intel ngo-1997 njengengxenye yokuxhumana okuhamba kancane kwePeripheral Component Interconnect (PCI).
I-AGP inikeza ukuxhumana ngokuqondile ku- CPU ne- RAM , okuphikisana nayo ivumela ukunikezwa kwamahluzo okusheshayo.
Enye ngcono okukhulu i-AGP inamaphakheji we-PCI ukuthi isebenza kanjani ne-RAM. Okubizwa ngokuthi inkumbulo ye-AGP, noma inkumbulo engekho yangakini, i-AGP ikwazi ukufinyelela imemori yesistimu ngqo kunokuthembela kuphela kwimemori yekhadi levidyo.
Imemori ye-AGP ivumela amakhadi we-AGP ukuba agweme ukugcina ukugcina amamephu (okungase asebenzise iningi lememori) ekhadini ngokwalo ngoba libagcine endaweni yememori yesistimu esikhundleni. Lokhu akusho nje ukuthi isivinini esikhulu se-AGP sithuthukiswa ngokuhambisana ne-PCI, kodwa futhi ukuthi umkhawulo wesayizi wamayunithi wokuthutha awusatholakali ngenani lememori ekhadini legrafu.
Ikhadi lehluzo le-PCI lithola ulwazi "kumaqembu" ngaphambi kokuthi lisetshenziswe, esikhundleni sayo konke ngesikhathi esisodwa. Isibonelo, ngenkathi ikhadi lehluzo le-PCI lizoqoqa ukuphakama, ubude, nobubanzi besithombe ngezikhathi ezintathu ezihlukene, bese ubahlanganisa ndawonye ukwakha isithombe, i-AGP ingathola lonke lolo lwazi ngesikhathi esisodwa. Lokhu kwenza ihluzo ezilula futhi ezibushelelezi kunalokho ongakubona ngekhadi le-PCI.
Ibhasi le-PCI livame ukugijimela ngesivinini se-33 MHz, sivumele ukuba sidlulise idatha ku-132 MB / s. Ukusebenzisa itafula kusuka phezulu, ungabona ukuthi i-AGP 3.0 ikwazi ukugijima izikhathi ezingaphezu kuka-16 ukuthi ijubane lidlulisele idatha ngokushesha, futhi ngisho ne-AGP 1.0 idlula ijubane le-PCI ngesici sezinto ezimbili.
Qaphela: Ngenkathi i-AGP ishintshe i-PCI ihluzo, i- PCIe (i-PCI Express) ishintshile i-AGP njenge-interface ejwayelekile yekhadi levidiyo, isiphelile ngokuphelele ngo-2010.
Ukuhambisana kwe-AGP
Amabhodi omama asekela i-AGP azoba nesiteleka esitholakalayo kwikhadi levidiyo le-AGP noma azobe e-AGP.
Ama-video we-AGP 3.0 angasetshenziswa ebhodini le-motherboard elisekela i-AGP 2.0 kuphela, kodwa lizokhawulelwa kulokho i-motherboard isekela, hhayi lokho okushiwo ikhadi legrafu. Ngamanye amazwi, ibhodi le-motherboard ngeke livumele ikhadi levidiyo ukuthi libe ngcono ngoba nje liyikhadi le-AGP 3.0; i-motherboard ngokwayo ayikwazi ukuhamba okunjalo (kule simo).
Amanye amabhodi omama asebenzisa kuphela i-AGP 3.0 angeke asekele amakhadi ase-AGP 2.0 amadala. Ngakho-ke, esimweni esivelele esivela ngenhla, ikhadi levidyo lingase lingasebenzi ngisho ngaphandle kokuthi likwazi ukusebenza ngesikhombimsebenzisi esisha.
Ama-slots e-Universal AGP ayatholakala ukuthi asekela amakhodi we-1.5 V no-3.3 V, kanye namakhadi wendawo yonke.
Ezinye izinhlelo zokusebenza , njenge-Windows 95, azisekeli i-AGP ngenxa yokungabi nesekelo lokushayela . Ezinye izinhlelo zokusebenza, njenge-Windows 98 nge- Windows XP , zidinga ukulanda umshayeli we-chipset we-AGP 8X ukwesekwa.
Ukufaka iKhadi le-AGP
Ukufaka ikhadi elihluziwe kwi-slot yokwandisa kufanele kube inqubo elula kakhulu. Ungabona ukuthi lokhu kwenziwa kanjani ngokulandela izinyathelo nezithombe kulokhu Ukufaka isifundo se-AGP Graphics Card .
Uma unenkinga ngekhadi levidiyo esevele selifakiwe , cabanga ngokuvuselela ikhadi . Lokhu kuya ku-AGP, PCI, noma i-PCI Express.
Okubalulekile: Hlola ibhodi lakho lomama noma ikhompiyutha ngaphambi kokuthenga nokufaka ikhadi elisha le-AGP . Ukufaka ikhadi levidiyo le-AGP elingasekelwa yi-motherboard yakho ngeke lisebenze futhi lingalimaza i-PC yakho.
