NVIDIA, lo GeForce 8500 GT: iinkcukacha, izimvo

ummeli mali lwe thotho yesibhozo amakhadi iigrafiki yokugqibela-ngezizukulwana ngenkankulu uya isibheno abalandeli imidlalo olutshintshatshintshayo resource-olunzulu. Nangona kunjalo, lo ngowona zombini NVIDIA GeForce 8500 GT umiselwe ukuba athathe i-niche Izixhobo obubobu yokuqala ungakhuphisana kunye izisombululo ehlangeneyo imalike nezincedisi computer. Kweli nqaku umfundi ukuba aqhelane umdla bangasukela namafutha (3000 engange) imizobo, uyakuqonda yokusebenza lalo kunye. Ukuphonononga ze abanikazi kuya kunceda ukubona zonke izinto ezingalunganga, apho umenzi cwaka.

Budget G86 iprosesa yemizobo, eyenzelwe 80 technology NM, ine power eliphantsi ngokufanelekileyo - watts-30 kuphela bomthwalo. Ngako oko, abasebenzisi imibuzo emininzi malunga nesakhono ukukhawulezisa, ezinako ikhadi yemizobo NVIDIA GeForce 8500 GT. iinkcukacha ezichaza umsebenzi, kwamkelekile ukusebenza neresursoomkimi imidlalo obuluqilima kunye nezicelo:

• engundoqo yemizobo basebenzisa rhoqo 450 MHz e;
• Shaders frequency ephumelelayo 900 MHz;
• GDDR3 imemori isebenzisa bit-128 ibhasi kwaye ixhasa amaza 800 MHz;

Kuphela kuphazamisa isixa RAM efakwe kwi namafutha yemizobo, - abangama-512 MB. Ngamanye amaxesha emarikeni uyakwazi ukufumana ikhadi yemizobo, ezifakwe 256 megabytes of RAM, nto leyo ebangela ngokubanzi ukudideka phakathi kubasebenzisi abaninzi. Ukuze isebenze i iadaptha vidiyo isebenzisa PCIex16 ibhasi, nangona kunjalo, kukuzikumbuza bokuqala.

main Idols

Nayiphi na imveliso ekhoyo kwimarike computer, kukho analogu oluphuculweyo imveliso okhuphisana '. Kakade ke, NVIDIA uyawalwela lobuntshatsheli kunye AMD kraca. ikhadi levidiyo NVIDIA GeForce GT 8500, iimpawu ezo zijolise ngakumbi ekupheleni ephantsi-ceke, imarike kukho iqela umdla kakhulu - ATI Radeon X1650 Pro. Ezimbini ividiyo phantse twatse imbonakalo kunye nobugcisa neempawu, ngenxa yokuba yintoni kwaye kukho impikiswano elininzi oyilwayo zokuveza.

Zombini yemizobo namafutha akukho lifuna isondlo, intsebenzo yabo ekumgangatho ofanayo, kodwa abasebenzisi abaninzi baye bakwazi ukufumana umahluko enye ebalulekileyo. Elidityaniswe ngevidiyo eyakhelwe-ngaphakathi capture isilawuli (Vivo) AMD kraca. Isimanga, umenzi NVIDIA ukuba ubekele ngezityholo ezifanayo, ngokuba jonga eklasini mali emva kwabo abayili iigrafiki ezininzi, abahleli kunye nabantu creative.

namafutha ifuna

Enoba udidi ikhadi levidiyo wayengekho, uya kusoloko ukufumana umthengi, kodwa, ukongeza yokusebenza, abasebenzisi abaninzi anomdla komnye umsebenzi osemqoka isixhobo - kumsebenzi cwaka. Ngapha koko, wonke umntu ufuna ukusebenza uze uphumle ngoxolo kwaye hayi ukuba ukumamela howls okupholisa fan ngesantya esiphezulu. It is a bafuna-emva isenza umgangatho ingqalelo ikhadi levidiyo NVIDIA GeForce 8500 GT, iimpawu zezobugcisa musa ukuvumela ngundoqo yemizobo ukuba shushu ngokugqithisileyo.

Bokwenziwa ngokuthi ibloko eyahlukileyo zonke iibhetri kwiqela lenjongo nojongano, eshiya indawo amcaba umqhubekekisi kunye memory. Ngokuqhelekileyo, abenzi abaninzi abasebenzise ezi ezisebenza ngokubakho umboniso, sentlalo ubhedu okanye aluminiyamu kwiradiyetha endaweni i-injini esebenzayo.

Ngo-mveliso setting

ummeli yohlahlo has a ubukhulu encinane emzimbeni (160h100h15 mm), ukuvumela ukuba zibekwe naphi kwinkqubo unit le, kuquka micro-ATX kunye Barabone. Kuba ukufakelwa iimfuno ikhadi yemizobo indawo yokubeka into kuphela, nto leyo kakhulu lula ekuqokelelweni iikhompyutha yemaltimidiya eziya kusetyenziswa ikhadi PCI ukwanda. Kuphela kuphazamisa lenjongo yekhompyutha kolihlwempu NVIDIA GeForce 8500 iadaptha GT yevidiyo. Uphawu abasebenzisi abaninzi engonelisekanga, kuba izihlanganisi i VGA, le DVI kunye TV-phandle ugugile, kwaye uqhagamshelwano lwetshiphu emsebenzi kuya kuphucula imeko.

Iziqalelo amandla ukuya PCB imibuzo wabuza: umenzi abafake capacitors yesiqhelo electrolytic ukuba phantse akukho ubushushu. Malunga izigaba kunye nokusasazwa amandla, nathi, musa ukuba ukucacisa ukuba isibonelelo lwamandla kwi namafutha yemizobo ukuze. Sinokuba phawula kuphela ilungiselelo engaqhelekanga iterminal loqhakamshelwano fan okupholisa. Le ibekwe kufuphi PCIex16 zoqhagamshelwano kwaye kuhlala slot of the motherboard xa kokufaka ikhadi.

Iimpawu hardware

Ezitsala ingqalelo namafutha graphic NVIDIA GeForce 8500 GT kukuba nshita yesisombululo esidibeneyo, ixhasa zonke API yethala leencwadi ekhoyo, yaye ngoko, uyakwazi ukusebenza kwayo nayiphi na imeko yophuhliso software. An Ibhonasi added iyahambelana ngokupheleleyo iDirectX 10 Noko ke, emva kokukhululwa of version 12 kwithala leencwadi ezithandwayo, igophe iphelelwe ukufaneleka kwayo.

imodeli Shader 4.0 kwaye nikeza uluhlu olutshintshayo 128-bit phenyane ingongoma, kakhulu, ikhangeleke ngokungathi kukho into blankly kwi isixhobo mali. Ngoko ke, xa uthenga le ikhadi levidiyo umsebenzisi kufuneka bacinge malunga kukhetho lo CPU enamandla ye computer yakho, ngenxa yokuba izikhohlakali zingamoyiki ukuba bathembele kwintsebenzo namafutha.

Engaziqhelanga eklasini mali

Kuyamangalisa ukuba yimveliso umdla elolo hlobo amkelwa kbavelisi ezaziwayo-kakuhle ezingenamandla ze amakhadi yevidiyo. Kuyabonakala ukuba, ukunqongophala besikhundla imidlalo resource-olunzulu kunye izicelo kwabatyhafisa nje umdla yemiyinge ethandwayo. Emakethe zomhlaba ikhadi ividiyo NVIDIA GeForce 8500 GT bubonakaliswe abenzi elinesibini enye kuphela afundisa umsebenzisi ekupheleni isisombululo cwaka kwiqonga ikhaya okanye i-ofisi ikhompyutha.

Technology Corp. Elitegroup, MSI kunye Biostar wagqiba ukuba bangachithi ixesha imveliso, ekuqinisekiseni ukuphola yayo ngexabiso kakhulu kwaye kukhulula emarikeni. abenzi eTaiwan Asus kunye Gigabyte ahlonele kwaye wenza namafutha uphuculo minor imizobo. Okokuqala, kumzi-mveliso phantsi PCB wadala inkqubo olupholisa ezisekelwe zezobhedu. Kananjalo wenza overclock encinane undoqo yemizobo, nelenyuse imveliso ye vidiyo.

Testing kunye nemizobo overclocking namafutha

NVIDIA GeForce 8500 isixhobo GT na impahla encinane nobushushu, yaye ke ngoko kubangela abanini amaninzi ukwandisa imveliso ngokuvusa i core yemizobo iprosesa frequency. Njengoko ibonisa yokusebenza, abameli lwabiwo-mali, njengoko kuchasene makhadi yemizobo iklasi zomdlalo abe ezininzi iingxaki kuphazamise overclocking. Iimodyuli memory efakiweyo kulinganiselwe rhoqo, ngoko ukuze amaza kwama 800 MHz ayikwazi ibe kwinqanaba zekhompyutha le.

yemizobo luvumelana core overclocking - 600MHz ngokuba kuye ngesantya ngokwenene, kangangokuba kuphela capacitors electrolytic kwinkqubo ngamandla le baba shushu kakhulu. Ngako oko, kubalulekile ukuba lokucinga lungapholi lwabo. abathanda abaninzi abaye landisa amaza GPU, kucetyiswa ukuba ukuqinisekisa nokususwa eyiyo ubushushu ukusuka kwinkqubo unit kwakunye ukusebenza kakuhle fan ikhadi yemizobo amagqabi kangako.

Ingxelo evela kubasebenzisi

Video iadaptha iSADC overclocking, yaye lo nesidima. Ngaphezu koko, kukukhawuleziswa kwimeko engcono, ukuya kwi-20% kwi NVIDIA GeForce engundoqo 8500 graphics GT. Izimvo yabanini kuphela imfuneko ukuqinisekisa kobubi ophucukileyo zonke iziqalelo ze ibhodi yesekethe eprintiweyo. Kwelinye icala, naziphi ukukhawulezisa okubonakalayo inceda ukuphucula intsebenzo ikhadi levidiyo, kodwa kule meko isiphumo phantse imperceptible. Kulo efanayo edume yokudlala «World of Amatanki» umsebenzisi uya kunyuka nge ezimbini kuphela ngesekhondi (25 ubuncinane useto yokuzonwabisa umgangatho 27 FPS).

Ukuba Ungashiya samandla yokudlala, iingenelo ingabonwa ixeshana elide. Inkxaso iDirectX 10 API neelayibrari likuvumela ukuba ukusebenza kwindawo igunya ngaphandle iingxaki, kunye hardware kakhulu uze ubacele imizobo 3D nokuba ngumzekelo ezintsonkothileyo. Akukho mfuneko ukufumana umbane, ngokungathandabuzekiyo, i plus na umthengi, leyo ulondoloze imali ukuthenga ikhompyutha, kuba PSU enamandla lubiza kakhulu.

Ekuphetheni

Kukhuselekile ukuba ukugqiba ukuba nabadlala (nokuba ukubonelela olunzulu) ikhadi levidiyo NVIDIA GeForce 8500 GT akufanelekanga. Iingcali bacebisa ukuba anikele ingqalelo imodeli entsha isizukulwana ophawulwe GTX. Nokuba kunikwa ukuba ikhadi yemizobo unako ukusebenza kwimo SLI, intsebenzo amalungelo yokudlala ayinayo. Ngapha koko, into ebalulekileyo kukuba inkxaso iilayibrari iDirectX.

Kodwa namafutha graphic umsebenzi kunye nobuchule sisisombululo iindleko-kuphumelela ibe yamkelekile. Makhe ukhetho emarikeni hayi nje enkulu, kodwa ukufumana isixhobo ofanelekileyo kunokwenzeka.
