Graphics ikhadi nVidia GeForce GTX 680: isishwankathelo iimpawu kunye nohlolo

Graphics namafutha, i nVidia i GeForce le GTX 680 umenzi sele ibekwe umdlalo kokuqala eklasini, kodwa abasebenzisi abaninzi ukubuyekeza kwabo bathi Ufanele ukuba akhuphisane izixhobo ezixabisa kakhulu abangakwaziyo zobungcali kurhwebo ikhadi levidiyo ukuba isakhono bevidiyo. Kweli nqaku, umfundi unikwa ithuba lokuxhamla enye engenelela eziphambili kurhwebo lwasekhaya, onako ukumelana nje kuphela naziphi zokudlala resource-olunzulu, kodwa zibonisa umsebenzi oncomekayo ngezicelo ezifuna ukusebenza eliphezulu kwi computer. Amagqabantshintshi iimpawu kunye nohlaziyo ze abanikazi kuya kunceda abasebenzisi kwenza ukhetho wasekunene kwicandelo yevidiyo.

UKumkani ufile, Makadle ubomi ukumkani!

Graphics ikhadi nVidia GeForce GTX 680 wayefanele ukuba ibe isantya eqhelekileyo izinto zazivelela zamakhadi yemizobo yokudlala abangakwaziyo ophezulu eklasini ukubuyisela iigrafiki lixesha ikhadi GTX 580. Noko ke, izinto azizange zihambe ngendlela ecwangcisiweyo ngumvelisi. Isizathu sokuba leyo Ukutshintsha kubuxhakaxhaka bokuvelisa chip ukusuka 40 nanometer ukuya 28 Kunye ukuhla kwamandla, ngathi ngembonakalo yikristale lehla isizukulwana ubushushu, yaye ngoko, nj ndafumana kunethuba elikhulu ukusebenza zizakwandiswa overclocking.

Kubalulekile ukuphawula ukuba obu bugcisa kwaye wadala yonke uluhlu amakhadi ezinamandla ividiyo ukusetyenziswa yobungcali kwi izibalo ekusetyenzweni isiqophi kanye 3D-ngumzekelo. Noko ke, umenzi uye wabandakanyeka kwiinkqubo ezifana eqongeni multiprocessor. Akubuzwa, amakhadi ezimbini okanye ezintathu GTX 680 amakhadi chip-esekelwe kwindlela SLI babonisa result okulungileyo izibalo efanayo.

iimpawu technical

GTX 680 chip iye codenamed GK104. On ngumenzi chip oyedwa ukubeka transistors 3.5 billion, ngokusebenzisa indawo yomgangatho 294 mm ^2. Hardware iDirectX inkxaso-11 kunye shaders ukuguqulwa 5th ngundoqo yokusebenza aphezulu imidlalo, ezinako imizobo nVidia GeForce GTX 680. Iimpawu operability olusebenzayo enikiweyo bit-265 memory ibhasi, ukwakhiwa ithekhinoloji GDDR5. Kuye kwenziwa ngohlobo ezine nabaqondisi 64 bit-ngokubanzi esizimeleyo ngasinye.

Umthamo yevidiyo RAM i-2 GB, kodwa isondlo kunokwenzeka ukuba sicinge ukuba abanye abenzi unqwenela ukunyusa ubungakanani RAM ye namafutha ukuya gigabytes-3 okanye ezi-4. Bephumelela ngokufaka inkumbulo iitshiphusi, kodwa akuyi kuchaphazela bandwidth ebhasini kuyitshintsha, ekubeni oku kungenzeka kuphela iintsimbi.

Power High Isalathisi

Ngokunciphisa ubushushu ukusasaza ikhadi eziphuculweyo ividiyo nVidia GeForce GTX 680 yemizobo ezingundoqo iimpawu. Sehla isithintelo zengqondo 1 GHz, umenzi unimisele isinyuko zisezantsi crystal of 1006 MHz. Noko ke, ngokutsho iingxelo ezenziwe ngabanikazi abaninzi, olu khetho wasentsomini kwaye, njengokuba kusenziwa ibonisa, lo iadaptha ividiyo unako ngakumbi.

Njengoko kwiinguqulelo kumgca lwangaphambili nVidia, nozinzo nokusebenza isixhobo ixhomekeke ngqo kwi zokupholisa, ngoko ukusebenza chips abenzi ezahlukeneyo amakhadi kwicandelo ebaleni iya kuba nempumelelo kuphela xa kukho liphole ufanele ukususwa ubushushu. Noko ke, kukho sele umsebenzisi kuya kufuneka ukuba ukhethe phakathi ixabiso kunye nokusebenza kweqonga kwakunye izisombululo ebonelelwe emarikeni, akunguye imin segolide.

Technologies nokuzala kwazo

Ukuthenga chip nVidia GeForce GTX 680 ncomo, sinokugqiba ukuba ikhadi yevidiyo yimveliso ogqityiweyo. Okokuqala, lo ngembonakalo yikristale iMisebenzi amandla ezipheleleyo (akukho itshixiwe kwi mveliso), kwaye ngokucacileyo uya kumkholisa nawuphi na umsebenzisi. Ingongoma yesibini ukuxhasa zonke ubugcisa ezikhoyo emarikeni multimedia kunye zomdlalo ingxenye. Sithetha lweeHedfowuni okusebenza 3D, inkxaso imiboniso ezininzi ukukhawulezisa yemizobo imveliso yazo zonke iziboniso adityaniswe amathuba ukusebenzisa nomkhenkce kwindlela CUDA.

Kuphela ephambanisa yakhiwe - eyakha lezo graphic isilawuli namafutha scripting nokunciphisa ngokuzenzekela kumaza a kernel elula. A akucaci kancinane kutheni ukunciphisa amandla kwaye sele ukonga kwi yikristale, ngenxa yokuba, ngokusengqiqweni, abasebenzisi kufuneka ukusebenza, nto leyo ukusebenza kweloo chip imo GPU Boost.

izisombululo Mobile nVidia

izinciphiso avele kwi core xa lingasetyenziswa nVidia GeForce GTX 680 accelerators mifanekiso kwakuchaziwe emva ntetho kwihlabathi laptops kunye ikhadi obubobu imizobo ezifakwe ngokususela chip efanayo. Kwinkqubo lovavanyo ukubuyekeza kwalo nencwadi, kwafunyaniswa ukuba ekuqaleni umenzi sineenjongo lentengiso izixhobo eziphathwayo. Eli liqonga mobile kwaza kwaveliswa chip iindleko-olusebenzayo.

Ukuthelekisa indlela yokusebenza imidlalo PC Notebook ngamakhadi imizobo GTX 680M kunye GTX 580M, abasebenzisi baye bafikelela kwisigqibo sokuba inkampani iteknoloji i nVidia nje zisuswe AMD market okhuphisana ngokunika ehlabathini eqolo kunye ngempumelelo kakhulu. Ngoko ke, ixabiso laptop gaming ingxenye kunye namafutha entsha engaphenduli ngaphezulu 50 000 engange (leyo yi-10% ngaphezulu ngaphezu izixhobo sangaphambili). Ngoxa imveliso eqongeni linyuke nge-35%. Lidla sisibonelelo omhle nabadlala.

Umvuzo studio!

Umthengi bazo uye waphawula ukuba imarike zasekhaya lizele izisombululo ezisekelwe nVidia GeForce GTX 680, nto leyo phantse twatse imbonakalo. Ezizezi - inkqubo injini enye ezininzi amakhadi ividiyo yomvelisi. Njengoko kuboniswe iimvavanyo, motherboard kunye chip neebhetri abekho phantsi ubushushu ngokugqithiseleyo, abenzi abaninzi baye bagqiba kwelokuba ashiye inkampani nVidia kupholile mveliso sentlalo, kwaye umaka imveliso babo sticker oqhelekileyo athunyelwa umzimba sisigubungelo radiator.

I plate aluminium kujikelezo yonke ividiyo kunye turbofan istili ezivaliweyo ngokupheleleyo kususa ngokupheleleyo ubushushu kuzo iziqalelo ifowuni. 28 nanometer ubuchwepheshe waba ngokucacileyo nempembelelo entle nj. kuphela kuziwa amakhadi mifanekiso angakhange bahlukana ngabavelisi kwi-mveliso.

Kuphela iinkwenkwezi ngasentla

Nangona kunjalo, uhlobo eTaiwan ezaziwayo-kakuhle iye kwakhona wayefuna kusimangalise abalandeli bakhe, waza wabonakala phezu kwimarike ivideo ikhadi Asus nVidia GeForce GTX 680, nto leyo inkqubo yabo wedwa ukupholisa, kodwa unenzondelelo ukukhawulezisa kakhulu. Ukwandisa frequency ezingundoqo ukuya ku 1300 MHz, inkampani iteknoloji i ikwazile ukunyusa ukusebenza isixhobo phantse-20%. Limited ukuba ube yinkokheli iimarike banyusa nabathengi ukhetho izisombululo-2 kunye gigabytes 4 RAM ebhodini.

Emva ezintsha zamakhadi imizobo Asus kwimarike kukho iimveliso phantsi brand MSI, Zotac, Palit, kunye nabanye abenzi ezaziwayo-kakuhle. Bonke ukwabelana-mveliso omkhulu overclock le GPU kunye nenkqubo olupholisa lobunikazi. Yiloo nto ke ukhetho kuphela ukuba kunzima kakhulu, kuba nj lo umlinganiselo ngqo ukusebenza kunye neendleko eyandisiweyo imveliso (hayi ngaphantsi kwe-20,000 engange).

Ekuphetheni

Le iadaptha ividiyo esekelwe kwi nVidia GeForce GTX 680 ngokuqinisekileyo uya isibheno bonke abathanda imidlalo resource-kakhulu, kodwa ngokufunda uhlolo kunye novavanyo, abathengi abaninzi kho iya kuba unpleasantly ukumangaliswa. Isibakala sokuba ikhadi levidiyo nelelalela elikhulu igunya, nto leyo eya kukwazi ukuba ubutyhile isakhono kuphela xa kukho udidi ohambelana ye-CPU umdlalo. Emva kokuba athole namafutha imali eninzi kwaye usebenzise isiqingatha umthamo wayo ngokungakhathali.

Phantsi yokudlala ikhadi levidiyo kuya kufuneka ukuba indawo ngokupheleleyo iqonga wokudlala, kungenjalo kuba nako ukuphumeza ukusebenza eliphezulu. Iingcali IT bacebisa ukusetyenziswa iziqhubekisi multi-core zinamandla umgca i3 Core ephakamileyo. Ukuba sithetha ngayo iimveliso AMD, kubhetele ukuqala nge kumaqonga-4-core.
