NVIDIA GeForce 8500 GT khadi la zithunzi: malingaliro, ndemanga

Chiwonetsero cha bajeti cha mndandanda wachisanu ndi chitatu cha makhadi owonetsera makanema sichikuwoneka kuti akudandaula kwa mafani a masewera amphamvu kwambiri. Komabe, ndi adapala ya NVIDIA GeForce 8500 GT yomwe imayenera kukhala ndi chida choyambirira cha zipangizo zomwe zingathe kupikisana ndi njira zowonjezera pamsika wamakina. M'nkhaniyi owerenga adziŵa bwino ndi zosangalatsa komanso zodula (3000 rubles) zojambula zamagetsi, phunzirani zomwe zingatheke komanso zamakono. Ndemanga za eni ake zidzakuthandizira kuwona zolephera zonse ndi ulemu zomwe wopanga amakhala chete nazo.

Zizindikiro za chip

GPU GPU ya bajeti, yomwe idagwiritsidwa ntchito ndi 80 nm tekinoloje, imakhala ndi mphamvu yogwiritsira ntchito bwino - ma Watts 30 okha muyeso yapamwamba katundu. Choncho, ogwiritsa ntchito ali ndi mafunso ambiri onena za zomwe zingapangitse kudumpha, zomwe zimatha kugwiritsa ntchito khadi la kanema NVIDIA GeForce 8500 GT. Zolemba zamakono zomwe zimatsimikiza kuti ntchito ndizovomerezeka kugwira ntchito ndi masewera olimbikitsa omwe sali othandiza kwambiri.

• Mafilimu opangira mafilimu amagwira ntchito pa 450 MHz;
• Nthawi zambiri shader nthawi zambiri ndi 900 MHz;
• Memphana GDDR3 imagwiritsa ntchito basi ya 128-bit ndikuthandiza pafupipafupi 800 MHz;

Amatsutsa kokha ma RAM omwe amaikidwa pa graphics accelerator - 512 MB zokha. Nthawi zina pamsika mukhoza kupeza makadi a makanema omwe ali ndi megabytes 256 ya RAM, zomwe, zimachititsa chisokonezo pakati pa ogwiritsa ntchito ambiri. Kuti agwire ntchito, adapotasi ya kanema amagwiritsa ntchito basi ya PCIex16, komabe, kukonzanso koyamba.

Wopikisana wamkulu

Chida chilichonse chomwe chili pamsika wa makompyuta ndizofanana ndi zofanana ndi zopangira makampani. Mwachibadwa, NVIDIA akulimbana ndi mpikisano ndi AMD brand. Khadi ya kanema ya NVIDIA GeForce 8500 GT, yomwe makhalidwe ake ali okhudzana ndi gawo la bajeti, ali ndi otsutsa kwambiri pamsika - ATI Radeon X1650 Pro. Ma adapala awiri a mavidiyo ali ofanana ndi maonekedwe ndi zamakono, chifukwa chake pali mikangano yambiri yotsutsa.

Mafilimu onse awiri omwe amawotcha mafilimu sakufuna mphamvu, ntchito zawo ndizofanana, koma ogwiritsa ntchito ambiri adapeza kusiyana kwakukulu. Icho chikugwirizana ndi womanga makina omangidwa muvidiyo (VIVO) kuchokera ku mtundu wa AMD. Zochititsa chidwi, wopanga NVIDIA sanapange mtengo womwewo, chifukwa opanga ambiri, okonza ndi anthu olenga amawonera makhadi a kanema mu kalasi ya bajeti.

Wotchedwa accelerator

Mukalasi iliyonse makanema adapatsa kanema analipo, nthawi zonse amapeza wogula, koma, kuphatikiza pa ntchito, ogwiritsa ntchito ambiri amasangalatsidwa ndi chida china - chopanda ntchito. Ndipotu, aliyense amafuna kugwira ntchito ndi kukhala chete, osamvetsera kulira kwa mkupi wakuzizira mofulumira. Ndi khalidwe lofunika kwambiri lomwe limakopa chidwi cha khadi la zithunzi la NVIDIA GeForce 8500 GT, zomwe zimapangitsa kuti mafilimu asamagwiritsidwe ntchito.

Wopanga watenga mbali yosiyana mabatire onse ku mawonekedwe a mawonekedwe, kusiya pulogalamu ndi pulosesa ndi kukumbukira. Mwachibadwa, ambiri opanga makadi a kanema ankagwiritsa ntchito mwayi umenewu poika mkuwa kapena radiator radiator mmalo mwa kutentha kake dongosolo.

Zapangidwe

Woimira bajeti ali ndi miyeso yaing'ono (160x100x15 mm), yomwe imaloleza kuti iyike mu chipangizo chilichonse, kuphatikizapo micro-ATX ndi Barabone. Pofuna kukweza khadi la kanema, chokhacho chimakhala chofunika, chomwe ndi chothandiza kwambiri pakusonkhanitsa makompyuta omwe angagwiritse ntchito makhadi owonjezera a PCI. Imangosokoneza pulogalamu yokhayokha yojambula muvidiyo ya NVIDIA GeForce 8500 GT. Makhalidwe a ogwiritsira ntchito ambiri sali okhutiritsa, chifukwa ogwirizanitsa VGA, DVI ndi TV-amatha kusintha khalidwe, ndipo HDMI ikhoza kuthetsa vutoli.

Palibe mafunso pazigawo zamagetsi pa bolodi la dera : wopanga amaikapo makina opangidwa ndi electrolytic, omwe samapserera. Pazigawo ndi kugawa mphamvu, nayenso, sangathe kulingalira, popeza mphamvu yowonjezera accelerator yatha. Mukhoza kungozindikira malo odabwitsa a osonkhana kuti mutsegule wotsekemera wowonongeka. Ili pafupi ndi ma PCIex16 ndipo imakhala pa bolodi la ma bokosi pamakina a kanema.

Zida zamagetsi

Mafilimu a NVIDIA GeForce 8500 GT amavomereza kuti mosiyana ndi njira zowonjezera, zimathandizira mabuku onse omwe alipo API, choncho amatha kugwira ntchito ndi malo osungira mapulogalamu. Bhonasi yowonjezereka ikugwirizana ndi DirectX 10, komabe, mutatha kutulutsidwa kwa la 12 la laibulale yotchukayi chidutswachi chataya ntchito yake.

Zithunzi zojambulajambula 4.0 ndi kutulutsa maina 128 pazomwe zikuyandama ndikuwoneka mopanda nzeru mu chipangizo cha bajeti. Choncho, mukamagula makasitomala a vidiyoyi, wogwiritsa ntchito ayenera kuganiza kuti akusankha pulosesa yamphamvu pa kompyuta yake, chifukwa ntchito ya accelerator siingakhoze kuwerengedwa.

Oddities mu kalasi ya bajeti

N'zosadabwitsa kuti chinthu chochititsa chidwi choterocho sichinazindikiridwe ndi opanga makhadi odziwika bwino a makanema. Mwachionekere, kusowa mphamvu mu masewera ndi ntchito zamagetsi zowonongeka zangotsitsa chidwi cha makampani otchuka. Msika wa mdziko NVIDIA GeForce 8500 GT amaimiridwa ndi ojambula khumi ndi awiri okha, omwe amapereka wogwiritsa ntchito yomaliza njira yabwino yopangira nyumba yamakono kapena kompyuta.

Makampani opanga zamakono Elitegroup, MSI ndi Biostar anasankha kuti asataya nthawi pa chipatsochi, akuchipereka ndi njira yotsika mtengo yozizira ndikuwamasula ku msika. Ojambula a ku Taiwan ASUS ndi Gigabyte amasonyeza kulemekeza kwambiri ndipo apanga makina opatsa mafilimu ang'onoang'ono. Choyamba, dongosolo lozizira lopangidwa ndi mkuwa linakhazikitsidwa pa chomera pa bolodi la dera losindikizidwa. Ndiponso anapanga chovala chapamwamba kwambiri cha zithunzi zojambulajambula, zomwe zinapangitsa kuti pulojekitiyo ikhale yogwira ntchito.

Kuyesedwa ndi kupitirira nsalu za graphic accelerator

Chipangizo cha NVIDIA GeForce 8500 GT chili ndi phukusi laching'ono lakutaya, ndipo motero amachititsa abambo ambiri kuwonjezera machitidwe a zojambulajambula powonjezera mafupipafupi a pulosesa. Monga momwe amasonyezera, oyimira bajeti, mosiyana ndi gulu la masewero a kanema, ali ndi mavuto ambiri omwe angalepheretse kupitirira. Maofesi omwe amaikidwa pamtima amakhala ndi malire ambiri, kotero ndizosatheka kutulutsa maulendo pamwamba pa 800 MHz pazomwe zimagwiritsidwa ntchito.

Mafilimu amtunduwu amamveka bwino kwambiri kuposa 600 MHz chifukwa zimakhala zovuta kwenikweni, koma ndi electrolytic capacitors yomwe imakhala yotentha kwambiri. Choncho, muyenera kuganizira za kuzizira kwawo. Ambiri okondwerera omwe adachulukitsa maulendo opanga mafilimu, amalimbikitsa kuti athandize kuchotsa kutentha kuchokera ku chipangizocho, monga momwe kanema wa kanema imathandizira kwambiri.

Mayankho ochokera kwa ogwiritsa ntchito

Wopatsa kanema wa kanema akhoza kudulidwa, ndipo ndi koyenera. Ndipo nsalu zapamwamba zowonjezereka zikufikira 20% pazithunzi za NVIDIA GeForce 8500 GT. Yankho la eni ake limangotanthauza kufunika kowonongeka bwino kwa zonse zomwe zili m'bwalo lozungulira. Kumbali ina, kunyalanyaza kulikonse kumapangitsa kuti zinthu ziwoneke bwino pakusintha kwa kanema wamakanema, koma pakadali pano zotsatira zake ziri zosawoneka. Mu chidole chomwecho "World of Tanks" wogwiritsa ntchito adzawona phindu la mafelemu awiri pamphindi (kuyambira 25 mpaka 27 FPS muzithunzi zochepa za khalidwe la vidiyo).

Ngati mumasiya masewerawa, ndiye kuti ubwino ukhoza kuwonanso pang'ono. Thandizo kwa makanema a DirectX 10 ndi API amakulolani kuti mugwire ntchito pa chitukuko popanda mavuto, ndipo kuthamanga kwa hardware kuli kotheka kuthana ndi zithunzi za 3D ndi zojambula zovuta. Kuperewera kwa zofunikira pa gawo la magetsi ndizophatikizapo ogula aliyense amene angathe kupulumutsa pogula makompyuta, chifukwa PS yamphamvu ndi yokwera mtengo kwambiri.

Pomaliza

Mukhoza kunena mosatsimikizirika kuti ojambula a masewera (osati ngakhale othandiza kwambiri) makasitomala a NVIDIA GeForce 8500 GT sakugwirizana. Akatswiri amalimbikitsa kulabadira zitsanzo za mbadwo watsopanowu ndi chizindikiro cha GTX. Ngakhale kuti kanema kanema imatha kugwira ntchito mu SLI mode, mulibe mwayi pa masewera. Ndipotu, chinthu chofunikira ndi chithandizo cha makanema a DirectX.

Koma monga kachipangizo kowonongeka kwa ntchito ndi chidziwitso, njira yothetsera mtengoyi idzakhala yolandiridwa. Lolani chisankho pamsika sichikulu, koma n'zotheka kupeza choyenera.
