Nvidia GTS 250: iimpawu kunye nohlaziyo

Graphics ikhadi Geforce GTS 250 - ke imodeli entsha kwi-G92 eqongeni GPU. Le ngezakhiwo imvelaphi yayo kude 2007, yaye kuphela emva kokukhutshwa ikhadi levidiyo ndimncinile abe nobomi yayo.

Isigqibo yokuqala kwikhadi yemizobo G92 8800 kunye nelingagcina umthamo we 512MB. Emva koko, le nkampani likhuphe Nvidia 9800 GTX kwaye 9800 GTX +. Yaba ingongoma lokugqibela kuphuhliso ukuguga eqongeni.

Ababhekisi bagqiba yayama yonke incindi kulo kwaye khupha GeForce GTS 250. Iimpawu elungisiweyo G92b yemizobo chip kubizwa ngokuba overclocking. Le iprosesa igqityiwe Nangona emarikeni kukho okhuphisana kwi ubuso Radeon 4850. kwanele ukukhuphisana kunye ikhadi elitsha evela AMD, ngoko kwagqitywa ukukhulula ividiyo ikhadi index GTS250. Lo mfuziselo lowo wokugqibela, nolwathi lwaphuhliswa kwi G92b.

iimpawu technical

Enyanisweni, GTS 250, iimpawu zazo, nangona kakhulu oluphuculweyo, uhlala enye 8800. Ekuphela kwento itshintshile - yiyo yokubakho qho kunye nokwanda memory mifanekiso. Model ngoku ecetyiweyo lunee ezimbini - 512 MB kunye 1 GB of inkumbulo.

Ngoko ke, ikhadi unalo engundoqo iwotshi rhoqo 738 MHz ne 1800 nokusetyenzwa MHz shader. Bandwidth Bus - 70 Gb / s. Ujongano ukudibanisa ikhadi yemizobo ukuya motherboard - PCI Express 2.0.

Zonke iinguqulelo ezahlula ukusuka siphu- GTS250 ikhadi levidiyo 9800, kwenziwa kwinqanaba software. Usekela PhysX, CUDA - zonke ezi utshintsho kwinqanaba umqhubi. Ngoko ke, sinokugqiba ukuba umsebenzi ebhodini bokwakha azikhange kuqhutywa. Nje indlela inzuzo le modeli ikhangeleka? Oku kamva bafunde uyokuvavanya.

Ngexesha le ikhadi levidiyo kubiza engange-6 ukuya ku-8, nto leyo evumela lula ukukhuphisana AMD kwicandelo ixabiso eliphakathi. Yoguqulelo nge-1 GB of inkumbulo kwafuneka ukuba ahlawule amawaka ambalwa kakhulu. Ekuqaleni, inkampani izicwangciso ukukhulula uguqulelo wesithathu waba Nvidia GTS 250, iimpawu lwazo ividiyo memory ezahlukeneyo kwi-2 GB. Kodwa ngenxa ukuthandwa ephantsi nokuthengisa ezincinci le mbono kwafuneka ukuba emkhenkceni. Ukususela kule ngokukhawuleza ukuziqonda ukuba izigqibo ezinjalo kumaqonga abadala Nvidia akazange eziletha impumelelo.

Asus and Palit

Ukuze ukuba angabi aluhlaza, sithatha amakhadi amabini ezithile kwiinkampani ezaziwayo-kakuhle. Eyokuqala kwezi - Asus GTS 250, kwaye eyesibini - Palit GTS 250. Zombini volume memory yi-512 MB. Okokuqala, cinga iimpawu zazo ngokweenkcukacha. simazi kakuhle ngoqwalaselo.

Asus GeForce GTS 250: Ukucacisa

Graphics ikhadi evela Asus kunye ncam yokuqala. Ne kuphela umahluko mnye: ukunyuka memory amaza 1900 MHz kwi ebhodini. Ngaphakathi kule bhokisi silindele iadaptha elinye icebo kuba PCI-E, intambo odiyo, CD bonke abaqhubi ukuba aye elichaphazelekayo ixesha lokunduluka, kunye nomyalelo. Ikhadi ngokwayo ibe ubungakanani obuncinane ngokulula sihambelana kakuhle iyunithi inkqubo yezindlu compact. Isixokelelwano sokupholisa iquka kwesibandisi elilodwa radiator. Kwicala elingasemva ezintathu isinxibelelanisi ngokuqhelekileyo kuhlala - uqhagamshelwano lwetshiphu emsebenzi, DVI kunye D-SUB. Zisasuka alunanto ngokupheleleyo - zonke chips zibekwe ngqo phantsi ezibandayo kunye kwiradiyetha, ethi ibonelele kuzo nge komoya elungileyo kunye namaqondo uhlise kwi imithwalo eliphezulu.

design okupholisa kwi GeForce GTS 250 512mb, iimpawu apho okungagqibekanga inzima kakhulu. Ezibandayo liqhagamshelene kwiradiyetha, kwaye heatpipes ezine. Nokuba sele umthwalo omkhulu kakhulu xa befuna imidlalo izilungiselelo yemizobo lobushushu isixhobo eliphezulu akazange avuke ngaphezu kweqondo 60 Celsius. Izinga lengxolo liphantsi kakhulu, kuqwalaselwa ixabiso mali kudidi kule modeli.

Palit GeForce GTS 250: Ukucacisa

Thina Kwathi ngomhla kwikhadi ividiyo Palit, iinkcukacha leyo asezantsi thile, kodwa ukusetyenziswa Ukwahluka kakhulu. Ibhokisi kunye nezixhobo standard Equipment - ezi ezisebenza ngokubakho efanayo, abaqhubi kunye nemiyalelo.

Ngaphandle, ibhodi ibonakala liqinile. Liphole kunye Ukupholisa ivale umzimba iplastiki iyakhanya. Ukongeza izihlanganisi standard kunye ujongano, kukho imveliso ividiyo uqhagamshelwano imo SLI (amakhadi ezintathu ividiyo efanayo zisebenze ngaxeshanye).

Isixokelelwano sokupholisa kulula kakhulu - i radiator elula top - kakhulu kupholile ingxolo. Iyaqondakala, ikhadi ividiyo evela Palit soloko khetho ngaphezulu mali. Ngenxa yale khadi itshiswe namandla kakhulu. Le eliphezulu lobushushu ibhalwe Celsius ngexesha vavanyo degrees 80. Kodwa izinga lengxolo omabini amakhadi malunga kwinqanaba elifanayo. Power kuselwe Palit ungaphantsana nje Asus GTS 250 512mb. Iimpawu ikhadi levidiyo kwi ezinye ukuphinda imodeli yangaphambili.

Kuba iimvavanyo imidlalo kunye neenkqubo, siye andinyulanga uqwalaselo PC elungeleleneyo. Iprosesa kuxhaswa yi-Intel - Core 2 Quad Quad-core 2.8 GHz engundoqo nganye. RAM 4 GB kunye hard drive ukuya 320 GB. Kwakhona sistemnike imiselwe ku-watt 850 ugesi. Le khompyutha iyasebenza Windows 7 64 Bit olusebenzisayo. Zonke iimvavanyo ziye zaqhutywa kwi sigqibo efanayo - 1680 x 1050 pixels.

eyayilwa

Kuba GTS 250 card imizobo, iimpawu zazo phantse ncam, le okhuphisanayo wakhethwa emntwini Radeon HD 4850. Le ememori okhuphisana efanayo - 512 MB. Ngokubanzi, onke amakhadi Bafunda kwiklasi enye. Ngapha koko, nkqu GTS 250 wadalwa ukuze okhuphisana ngqo umfuziselo AMD.

iziphumo zovavanyo

Umdlalo wokuqala yaba Call Of Duty World At War. Zombini amakhadi yemizobo GTS 250 banikwa fps 36-38. Graphics ikhadi evela AMD naye kude ngasemva - malunga nama-34 ngesekhondi.

iimvavanyo ezingaphaya eyathatyathiswa kumdlalo Mafia-2, nto leyo nayo ncam befuna kwi-hardware. Kwaye kwakhona onke amakhadi abonisa iziphumo efanayo ngokupheleleyo. Ngoko zonke iimodeli ezintathu zibonisa ukuhanjwa ngokupheleleyo nawuphi na umdlalo. Umahluko kuphela ubushushu zokufudumeza, ingxolo, ukusetyenziswa kwamandla kunye neendleko.

abanini Izimvo

Imarike ikhadi levidiyo ngelo xesha sele waye okroqiweyo inani elikhulu imifuziselo. Ngokutsho nokubuyekezwa abanini, uninzi wakhetha isisombululo evela, AMD. Umahluko yokusebenza ibe ncinci, kodwa iindleko yi Radeon sitshiphu. Ukongeza, nkqu Nvidia GTS 250 iifeni, iimpawu zazo kakhulu okulungileyo kwiqonga eziphelelwe lixesha, akazange abe iimvakalelo olufudumeleyo eli khadi ezihamba yemizobo lixesha, nangona yeentsali, akazange abenze nentembelo.

sinqumo

Platform G92 kunye G92b - enye lwazi bolwakhiwo lwempahla ezininzi gqolo ehlabathini amakhadi yevidiyo. Kaloku, bakulityhutyha ilizwe izizukulwana ezininzi amakhadi yevidiyo, chip yemizobo ufanelwe wayigqiba ubomi bakhe kwimodeli GTS card mifanekiso 250 iinkcukacha kwenza kube lula ukukhuphisana abangakwaziyo okhuphisana evela AMD. Okwangoku, ukufumana nayiphi na kwezi iibhodi kwenza akukho ingqiqo - kwaba phantsi kakhulu ngabakwenzayo. Kodwa ngaxa lithile baba zinkokheli ngqo eklasini yohlahlo lwabiwo-mali. Nangona kunjalo, i GTS 250 Baphela ukubetha imbangi yakhe kwiintengiso yaye bathandwe. Yaye ixabiso ngaphezu koko AMD kaThixo, akazange aye kungena lokwengeza ividiyo amakhadi GeForce.
