Ukukhetha kwethu amakhadi wevidiyo wedeskithophu esebenzisa isikhombimsebenzisi se-AGP esidala
Kuleli qophelo nesikhathi, i-AGP ayizange isetshenziswe kuma-desktop systems iminyaka eminingi. Ayikho isistimu entsha yesistimu futhi iningi lomakhi wekhadi levidiyo alikhipha amakhadi. Kodwa uma unekhompuyutha endala, ikhadi levidiyo ye-graph port (AGP) liyindlela ephumelelayo yokuqinisekisa ukuthi imodeli yakho yamanje ingakwazi ukusingatha ukuhumusha okuyisisekelo. Lokhu kusho izici ezifana ne-Direct X kanye namanye amakhono okudweba okungenzeka awazange asekelwe ngekhadi lehluzo elizinikezele. Ngaphezulu kwalokho, ukudlula ngokweqile i-PC yakho kuba lula kusukela kumakhadi we-AGP unikeza indlela ezinikezele phakathi kwe-slot kanye neprosesa ngaphandle kokuphazanyiswa.
Ngakho-ke siqala kuphi ekuthengeni eyodwa? Ngezansi sihambisane namakhadi we-AGP angcono kakhulu emakethe kuze kube yimanje ongafaka kukhompyutha yakho yangokwezifiso noma endala. Lokhu kuhlanganisa amayunithi angabizi kakhulu, kanye namakhadi akwazi ukukuchofoza kumkhawulo ngamanani wezinguqulo zanamuhla. Kuncike ekulindeni kwakho, kunamakhadi amaningi e-AGP ngaphandle kwakho.
Ngenye yezinga elide kakhulu - uma kungenjalo i-AGP yamakhadi ehluzo e-Amazon kuze kube yimanje yi-EVGA GeForce 6200. Ihamba kahle kakhulu futhi iza nenani elikhulu lokukhumbula imemori engu-512 MB, ngakho uzothola inani elihle le-oomph nge-RAM ekuqondeni ihluzo lakho.
Leli khadi lehluzo le-AGP lisekela i-DDR2 SDRAM futhi linokuxhumana kwe-PCIE yehadiwe. Iza ngejubane lokukhumbula i-clock ye-350 MHz futhi lihlanganisa ububanzi bhasi besikhombisi 512. Iyunithi ilinganisa u-7.5 x 11 x 1.5 amasentimitha angu-1.5.
Esinye sezici ezinhle kakhulu kwikhadi legrafu okufanele linikeze yi-24/7 yokusekela lobuchwepheshe yenkampani. Uma usu-jam noma udinga usizo lokuqonda ukusetha, shayela inkampani. Abasebenzisi be-Amazon abathengile umkhiqizo bathanda ukukwazi ukukwazi amandla ayo, futhi ukuthi ukuthuthukiswa okukhulu kwamakhompyutha amadala. Ababuyekezi ababucayi ababhekene nezinkinga ezithile zokuhambisana.
Ngisho noma ungafuni ukubeka imali engaphezulu kakhulu kukhompuyutha yakho endala, usengayiphatha ekuthuthukiseni i-Genuine Dell Nvidia GeForce 4. Inememori engama-64MB, okungenani ubuncane, kodwa okwamanje inketho enhle kakhulu kubathengi abaningi. Inikeza ukukhishwa okugcwele kwe-DVI & TV, okuvumela ukubonisa okuyisisekelo okusetshenziswe. Kungenzeka ukuthi ngaphezulu kwekhadi lokufaka esikhundleni uma kuqhathaniswa nabanye ohlwini, kodwa ababuyekezi be-Amazon bathanda ikhadi ngamanani alo aphansi futhi kulula ukuhambisana nemishini emidala. Isixwayiso esifanele: Noma kunjalo, ababuyekezi ababucayi abaluleka kakhulu babhekisela ekungabikho kobucwebe obuphansi bephrofayela.
Ufuna ikhadi lehluzo le-AGP elisekela i-DirectX 10 ne-Shadier Model 4.1 ukwesekwa? Ungabhekanga phambili. I-VisionTek i-Radeon 3450 yiyona i-AGP engcono kakhulu ohlwini oluzosekela okulindelekile nakwezinye izici zanamuhla.
I-Radeon 3450 ye-VisionTek ifakwe i-8x AGP Bus kanye no-55nm ubuchwepheshe bokusebenza. Ihlanganisa amayunithi angama-40 okusetshenziselwa ukusakaza, kanye nesikhombimsebenzisi se-memory-64 bit, okwenza kube enye yamakhadi AGP anamandla kakhulu ohlwini. Naphezu kwalo mandla, ugcina amandla okusebenzisa amandla afaka nobuchwepheshe be-ATI Power Play.
Abasebenzisi base-Amazon abathenge leli khadi bayalithanda ngenxa yamandla alo okugcoba nobuchwepheshe bokulondoloza amandla. Abanye bathi bahlatshwa umxhwele ikhono lekhadi lokusebenza nabaqaphi ababili ngokukhipha okubili. Ababuyekezi ababucayi kakhulu bayaqaphela ukuthi kunamanye okungahambisani nomshayeli kumasistimu abo.
Ufuna ikhadi le-AGP elingaba ngaphezu kwama-5.25 x 8 x 1.75 amayintshi? Kuthiwani ngomunye ohlinzeka nge-HDTV port ye-DVI ukuze akhiphe izinqumo kuze kube ngu-1024 x 768? Bese uhlole i-XFX PVT44AWANG GeForce 6200.
Ngenkampani yokucubungula ihluzo le-128-bit kanye nokwesekwa kwe-Microsoft DirectX 9.0 ne-Shader Model 3.0, i-XFX yi-AGP encane ephethe i-punch. Ihlonyelwe ukuchazwa okuphezulu kwe-MPEG-2 hardware yekhwalithi kanye nekhwalithi ephezulu yesikhathi sokuqopha ividiyo. Ihlinzeka inkumbulo engu-256 MB ye-256-bit futhi yakhiwe nge-architecture engakwazi ukusingatha isidingo semidlalo yemidlalo. Ikhadi iza nobuchwepheshe be-Intellisample 3.0 okwenza kube kuhle ukulwa nokulwa, ukubhebhethekisa imiphetho emihle futhi kuqinisekiswe imiphumela evelele yokuqhafaza.
Abasebenzisi base-Amazon badumisa umkhiqizo ngobukhulu bawo obukhulu, kanye nekhwalithi yayo enkulu ngentengo yayo. Ababuyekezi ababucayi kakhulu abakukhulume ukuthi kuhle kakhulu ekucubunguleni izithombe.
