GeForce 9800 GT: ntchito. NVDIA GeForce 9800 GT

Isanafike 9800 GT, akatswiri ambiri ndi atolankhani amakhulupirira kuti uthenga za maonekedwe a zithunzi adaputala zongopeka. Pambuyo nduna kumasulidwa nkhani chitakonzedwa. pasadakhale ambiri anapereka n'kukhutira wa Championship ichi khadi kanema monga flagship, koma NVIDIA akatswiri kuti kachiwiri anatuma latsopano nambala akale mapulani njira.

GeForce 9800 GT. makhalidwe a khadi kanema

Zithunzi accelerator pafupifupi buku wathunthu wa kuloŵedwa m'malo - ndi GeForce 8800 GT. Komanso, ena mayesero bwanji kuti mbadwo wakale ndi waphindu. Zachilendo waikidwa ndi purosesa chomwecho - G92, izo sanasinthe ngakhale njira luso. Iye anali 65 nm, ngakhale ambiri amakhulupirira kuti 9800 GT ntchito 55 nm. GPU pafupipafupi ndi sanasinthe.

Pa tsamba la pawebusaiti yovomerezeka, ife anapezerapo ndi GT GeForce 9800, anatchula makhalidwe zotsatirazi:

• GPU: G92. 112 chilengedwe mapurosesa 64 kapangidwe chipika.
• Video kukumbukira: GDDR3, voliyumu yake - 512 MB.
• Memory basi m'lifupi 256 Akamva.
• GPU pafupipafupi: 600 MHz.
• Pafupipafupi shader 1500 MHz.
• Memory pafupipafupi: 1800 (900) MHz.
• Madoko: 2xDVI-I, TV-Out.

Chinthu chokha chimene chimasiyanitsa ankaona kanema khadi kuchokera 8800 GT - HybridPower luso thandizo. Timatha inu kusinthana pakati Integrated ndi apawokha zithunzi khadi mu mode zodziwikiratu kuti amalola kuti kuchepetsa kumwa mphamvu ndi mlingo phokoso.

Kusintha izo sizingakhoze alembedwa gulu zofunikira pa GeForce 9800 ndi GT, makhalidwe a izi sizisintha Komanso HybridPower sungathe kugwira ntchito popanda kutsatira zinthu zomwezo. The mavabodi ayeneranso kuwathandiza njira imeneyi ndipo nthawi yomweyo kunyamula Integrated zithunzi pachimake.

Mungasankhe

Video khadi amabwera mu bokosi m'malo lalikulu, amene chokongoletsedwa ndi predominance a mitundu buluu.

Mkati mungapeze zotsatirazi:

• khadi Video yokha.
• Zogwiritsira adaputala azamagetsi: ndi DVI-ndi VGA, ndi DVI ndi HDMI, ndi S-ndi Video-tulip.
• Waya zapadera kudya.
• Laser chimbale ndi madalaivala ndi mapulogalamu.
• Ena revisions monga ya masewera Chitukuko IV.
• Guide malangizo.

Text kusindikizidwa pa ma CD, ali makamaka umaimiridwa ndi malonda. Komabe, pakati pa odes laudatory umisiri ntchito GT GeForce 9800 mankhwala, specifications amasonyeza mwachindunji wakumanga zithunzi accelerator zochokera 8800 GT. umphumphu Zimenezi zingakhale nsanje.

The ambiri adaputala azamagetsi ndi mphamvu chingwe zikusonyeza kuti NVIDIA amasamala za ogula. Ngati ndi kotheka, kulumikiza zida optional kapena oyang'anira angapo mulibe kugula Chalk owonjezera, udzakhala wokwanira kuti iwo kunja kwa bokosi.

kamangidwe

Mwina ananena kuti pamene akuyerekeza GeForce 8800 GT ndi GeForce 9800 makhalidwe GT a machesi awo ndiko kuposa kamangidwe. Inde, mawu onse, gulu lina akufanana china, koma kuti iwo zofanana, sikutheka.

Onse makadi ndi miyeso chomwecho, malo a cholumikizira kwa magetsi, kukhudzana SLI, yokutidwa ndi pulagi zopangidwa mphira, komanso malo a GPU ndi kukumbukira ICs. Chips yotentha ndi Samsung, ndi zochepa chabe pamalangizo nthawi 1 NS.

Malo madera otsala losiyana kotheratu. Komanso, akatswiri anaganiza kuti kupulumutsa ndi ntchito zipangizo ambiri apamwamba. khadi Tingaone capacitors olimba. The moyo utumiki wa malonda oterewa ndi zambiri osati electrolysis chikhalidwe. coils Choke ndi mitima ferrite ingapindulenso nthawi ya ntchito pa muyezo.

Ngati unsembe wa akatswiri michenga yopangira zida zamagetsi ndayesera, chiwerengero cha madoko kulumikiza zipangizo linanena bungwe bwino osati pamwamba wa oimira. Pali awiri DVI-I zolumikizira ndi chimodzi TV-Out. Koma izi imalipidwa ndi kupanda adaputala azamagetsi zonse zofunikira.

dongosolo kuzirala

Pa anayendera pafupi, NVIDIA GeForce 9800 GT, makhalidwe ake sakuwoneka chidwi. Komabe, pali pa likutipatsa accelerator mfundo angapereke osemphana ndi makadi ena ambiri - ichi ndi Redieta. Choyamba tisaiwale kuti anaika dongosolo kuzirala anamasula Zalman wotchuka German kampani, ndiwo atsogoleri a msika.

Linapangidwa zazing'ono ngati n'kotheka, koma ntchito mwakachetechete kwambiri ndi efficiently. Mwa kukhudza padziko GPU pachimake, pa chimene matenthedwe mafuta. Kudzera analilumpha angapo mipope isanu ndi millimeter chake, "U" mawonekedwe ndi ofanana kalatayo. Iwo zopangidwa ndi mkuwa. Pamwamba pa machubu zili woonda zotayidwa mbale.

Nawatsimikizira anamaliza dongosolo lonse otsika liwiro wononga awiri a masentimita 8. Kufulumira kasinthasintha amusankha basi malingana mlingo wa potsegula zithunzi. Chinthu chokha chimene akhoza zimachitika zolakwa za dongosolo yozizira - izo silingamveke ndi kagawo chachiwiri PCI Express. Ngati pali kufunika kuika awiri basi kanema khadi mu kompyuta, inu muyenera kuganizira m'malo rediyeta.

mathamangitsidwe

NVIDIA GeForce ndi GT 9800, makhalidwe amene ali wodzichepetsa, zikhoza omwazika ntchito mapulogalamu zinaphatikizapo ndi yobereka ndi. GamerHUD ntchito akhoza kusintha pafupipafupi pamene opaleshoni dongosolo popanda reboots zosafunika. Komanso, pulogalamu amalola kuchita mwai ndi voteji, omwe umaperekedwa pa GPU, koma ntchito mbali ali osavomerezeka, kotero kuti kanema purosesa si kunja kwa dongosolo.

Pambuyo mathamangitsidwe akupitiriza khola ntchito khadi GeForce 9800 GT, amene makhalidwe pafupipafupi akhala kuchuluka 700. MHz kwa GPU, ndi shader kwa 1700 MHz 2000 MHz wagawo kukumbukira. Kuchuluka kutentha pang'ono pambuyo overclocking, umene ndi kuthokoza dongosolo kuzirala.
