NVIDIA GeForce GT 720M. NVIDIA GeForce GT 720M ikhadi graphics

Uhlahlo ividiyo ikhadi zizixhobo eziphathwayo ngokusekelwe kwi-chip ye NVIDIA i GeForce GT 720m ngokugqithisileyo kangangokuba kunye amavo ukuba abasebenzisi abaninzi xa uthenga laptop ayikwazi ukwazi ukuba ukhetho. Eminye imithombo bathi ukuba ikhadi yemizobo asetyenziswe yokudlala mobile ummeli yeklasi thumbanails ongundoqo, ngoxa abanye ukunyanzelisa izimvo zabo malunga nokuthiywa chip sangaphambili.

Kweli nqaku, umfundi ufunda ukuba eneneni kukho mobile namafutha yemizobo GeForce GT 720M kunye nokuba kufuneka linike kuqala xa uthenga laptop. iimpawu zobugcisa chip, uvavanyo kunye nohlolo ze abanini baya kuzisa ukucaca kwesi sihloko.

uchulumanco angamanga

Isizathu sokuba ukucamanga kubasebenzisi abaninzi malunga nendlela yokusebenzisa i umphakathi yemizobo endala ukwenza chip i NVIDIA i GeForce GT 720m yaba ukuqatshelwa yomvelisi ngokwakhe. Abameli inkampani kwi website esemthethweni ingxelo ukuba ikhadi elitsha ividiyo, okanye mandithi ngumkhenkce yayo enombhalo GK208, wadala ngokufana ezingundoqo yemizobo GF117. Ukuba lentetho isizathu ekudalweni amarhe ukuba umenzi wathabatha ukusetyenziswa akhawunti ezibhaliweyo-off ukuya kwimveliso.

Yiloo nto kuphela kukho GPU Ukukhuthaza 2.0 ubugcisa, ethi ixhaswe chip GeForce GT 720M, ngandlel ngoyaba yi bempilo abaninzi. Kunye nenkxaso PhysX, CUDA, nguOptimus, iDirectX 11, akukho mntu ithetha. Njengoko iingcali kwiirivyu zabo, bebabaza ngokungenabulungisa ndadala sisezindongeni NVIDIA Corporation. Kuyabonakala ukuba, ngoko ke umenzi igqibe ukutsala abathengi ukuba izisombululo zayo zexabiso eliphantsi.

Iimpawu yokusebenza

Ukuze ividiyo phezu chip ye NVIDIA i GeForce GT iimpawu 720m yokusebenza ephezulu kunzima ukubiza. Okokuqala, yonke umfanekiso ungcolisa GDDR3 imemori esisebenza phezu bit-64 ibhasi. kwesithintelo bandwidth kwi khomputha nga uzakufun aukugqithisa nayiphi rhoqo aphezulu undoqo yemizobo, akukho memory chips overclocking. Njengalo okanye hayi, kukho umda ngaphaya ezenza kube nzima ukuba kukhawuleziswe.

Fermi bokwakha ixhasa 96 iziqhubekisi umsinga kwi NVIDIA GeForce GT 720M. Crystal into clocked kwi 938 MHz kunye nememori ngo-1000 inkxaso MHz. imemori bevidiyo kulinganiselwe 2048 MB. Ezi iinkcukacha ikhadi yemizobo obubobu ngendlela ekhethekile izisombululo esebenzayo, ehlanganisiweyo, kodwa umdlalo wabo kunzima kakhulu ukuba ukubiza.

A kundincedile ngokufuna abathengi

Sekunjalo ekhadini mobile nemizobo ekubuyekezeni chip NVIDIA GeForce GT 720M ezincomekayo. Inkxaso DirectX11 kunye Shader 5.0 nemizobo ukuba abasebenzisi yamanqaku ukudlala imidlalo yakutshanje, Noko ke, phezu yokusebenza setting liphantsi. technology CUDA kwenza izicelo resource-olunzulu ukusebenzisa amandla GPU kubalo (kumqhubekekisi ezongezelelweyo kwinkqubo). Hardware processing ividiyo imijelo e high quality, ukucazulula kunye output imifanekiso ku TV ngokuqinisekileyo uya isibheno abathandi multimedia.

Musa ukulibala malunga ugcino lwamandla omsebenzi osemqoka ye namafutha yemizobo. Kwimo nguOptimus yemizobo ungakwazi noba banoku cinywa, wayithumela isixhobo oluhlangeneyo ulawulo, okanye ukunciphisa amaza nokusebenza yikristale ukuya ubuncinane. Olu phawu yenzelwe Ultrabooks, apho kwiimpawu iphambili ebomini ibhetri ubomi bebhetri ngecala olulodwa. Ukukhulisa 2.0 mode, phezu koko, kwenyusa rhoqo umsebenzi ongundoqo kwi imithwalo eziphakamileyo, ephakamisa ukusebenza yonke ifowuni ephathwayo.

software Efficiency

Ikhadi yemizobo eliphezulu-komsebenzi, wakha phezu chip ye NVIDIA i GeForce le 720m GT, umqhubi lidlala indima. Bonke abanini laptops abanqwenela ukusebenzisa ifowuni ukuba iingcali ukuzonwabisa Siyaleza ukulandela kuhlaziyo ezintsha NVIDIA Corporation kunye ngokukhawuleza nokuhlaziya umqhubi yevidiyo mobile. Kwiimeko ezininzi, le software entsha esuka indawo esemthethweni yomvelisi iqulethe iseti ngokupheleleyo imiyalelo ezikuvumela ukuphucula ukusebenza izicelo nemidlalo yale mihla.

Kumajelo eendaba, oluninzi imiyalelo ukuvuselela ngayo BIOS sevidiyo mobile. Ewe, firmware esisigxina memory namafutha mifanekiso zinokuzisa ukusebenza imidlalo, kodwa kukho iingxaki ezininzi ezinokwenzeka ngenxa yezenzo engathethekiyo zabasebenzisi. Umzekelo, wenze le ikhadi levidiyo. Buyisela soldered kwi laptop motherboard chip eziyingxaki.

Analogs isampula endala

abasebenzisi abaninzi zama ukuthelekisa zokudlala chip entry-level GeForce GT 540M kunye NVIDIA GeForce GT 720M namafutha mobile. Iimpawu twatse, kwaye kwezi mvavanyo babonakalisa yokusebenza efanayo, kodwa ke eneneni zizixhobo ezimbini ezahlukeneyo ngokupheleleyo. Okokuqala, uthelekiso lwenzeka kwiinkqubo ezizodwa ezisebenza ngqo kunye engundoqo isixhobo lomzobo. Ngokuqhelekileyo, oko kuya kuxhomekeka kwi-frequency - oluphezulu oko kukuthi, kuvezwa ngcono. Enye into ebalulekileyo kukuba ububanzi ibhasi (y GT 540M kabini).

Xa kuziwa uvavanyo, kubhetele ukusebenzisa uthelekiso fair imidlalo okanye iinkqubo resource-olunzulu. Ngapha koko, i-software yenza ukuba ikhadi yemizobo ukutyhila iziphiwo zabo ngokupheleleyo kwaye usebenzise kubuchwepheshe hardware. Ngokutsho iziphumo imifuniselo, sinako ngokukhuselekileyo bathi GeForce GT 540M ayinakuba okhuphisana kwi mihla ikhadi yemizobo GeForce GT 720M, nabo bonke nohlolo kwi eendaba - yinto intsomi.

producer lamaqhinga Marketing

Practice lubonisa ukuba xa ukhetha laptop kunye chip NVIDIA GeForce GT 720M ixabiso yinto ebalulekileyo (iindleko igajethi - kwisithuba 22-35 amawaka engange). izixhobo twatse mobile evela kumthombo omnye yevidiyo, okudalwe ubuchwepheshe efanayo, kodwa kufuneka iinkozo ezahlukeneyo anokuba umahluko omkhulu kweendleko. Umzekelo yo fanekisela yi namafutha yemizobo ezisekelwe GeForce GT 740M. Yohluka ukusuka ividiyo kuqwalaselwa kuphela eziphuculweyo chips imemori asebenza kwi-bit-128 ibhasi lwetheknoloji GDDR5.

Kungovavanyo imidlalo, ukuze kuqwalaselwe ukuba ukwanda intsebenzo 12-15%, kodwa ke ixabiso kwiincwadana twatse amakhadi ezahlukeneyo ividiyo abafani 50-60%. Iingcali zithi le ngxaki owadalwa Apple Corporation, nto leyo eye wakhangela iimveliso zayo yokudlala ikhadi levidiyo kunye memory ibhasi ezihlaziyiweyo. Kubonakala ukuba ikhadi levidiyo NVIDIA GeForce GT 720M ngenxa urhwebo imidlalo umvelisi got umsantsa mali, ngoko ke ngabomi yi abathengi abaninzi xa ukhetha laptop.

Reviews abanikazi laptop

Izindululo iingcali IT kunye nabathengisi, abathengi abaninzi ezinokuba ngoyaba. Abantu abaninzi abanomdla izimvo zabamnini. Kuzo uyakwazi ukufumana inyaniso. Phakathi abasebenzisi ofisi abasebenzisa laptops kunye namafutha mifanekiso NVIDIA GeForce GT 720M, nemibono HIV kuphela. software Uninzi kufuna isixa esikhulu yinkumbulo phambi ubugcisa bale mihla, yaye le vidiyo ngendlela epheleleyo.

Kodwa abalandeli okudlala bakhawuleza bangamaqela amabini. Abantu abakhetha ukuba adlale a resource-olunzulu izicelo obuluqilima (Crysis 3, Call of Duty 4, Deus Ex 3, kwaye ezifana) babanga ukuba intsebenzo GT 720M ayikho ngokwaneleyo - ujonge izilayidi anemifanekiso 14 ngesekhondi kungelula. Le ikhadi levidiyo kuphela kuya isibheno abalandeli yokudlala World online lamatanki, Dota 2, StarCraft 2 kunye nezinye izicelo bafune.

Ekuphetheni

Ukushwankathela, singenza kwisigqibo kucace ukuba mobile namafutha yemizobo ezisekelwe NVIDIA GeForce GT 720M chip emele kwiklasi sokuqala somdlalo. Ukubeka lwesixhobo kwicandelo yohlahlo impazamo abathengisi abaninzi. Kwakhona, akukho apho lifune ukubaliswa kwe chip sangaphambili kubakho umbuzo - yinto namafutha eyahlukileyo graphic exhasa zonke zobugcisa zakutsha nje, kodwa kungaphelelanga (akwaziwa ukuba yintoni injongo) nomvelisi izinga ugqithiso lwedata phakathi chip kunye motherboard.
