NVIDIA GeForce GTX 480: iinkcukacha, izimvo, review

Xa izicelo olutshintshatshintshayo fan-olunzulu kukho umnqweno lokonwabela sicatshulwa into oyiphiweyo elandelayo zehlabathi umdlalo, uza kucinga malunga namathuba ikhadi yayo ngevidiyo efakiweyo kwinkqubo unit le. Kakade ke, njengoko ibonisa indlela, iyunithi mali kunye kwiiklasi ayidlaleki sokuqala nzima ngakumbi ukumelana imisebenzi. Phuma apha omnye - ukufumana ikhadi yemizobo High-Isiphelo GTX 480 yeklasi iminyaka 5-10 ukulibala malunga neengxaki ezinxulumene inhibition kwi zokudlala resource-olunzulu. Iimpawu, ukubuyekeza, uhlaziyo kunye uthelekiso nemveliso umntu okhuphisana ukuba ukunceda abathengi ukwenza ukhetho olufanelekileyo.

iimpawu technical

Chip codename Fermi zokumakisha GF100 wakha besebenzisa ubugcisa nanometer-40 apho kwenza umvelisi kuphela ukubonelela transistors ngakumbi a chip (3.2 billion), kunye namandla ukusetyenziswa esezantsi isixhobo yokudlala GeForce GTX 480. Iinkcukacha ubushushu ingadluli watts 250, ukuba eNkulu-Ukuphela luphawu olukhulu. iadaptha yevidiyo yangamacandelo amane zokulungisa igrafikhi umsinga idatha multiprocessors-15 ne-480 kernels CUDA. Graphics iprosesa, njengoko yakhiwe, ukuba clocked kwi 700 MHz. Video memory chips kwakheka kwi GDDR5, ngaba inobunzima 1.5 GB kwaye isebenza kwi bit-384 ibhasi. imemori frequency esiphumelelayo 3696 MHz.

ubuchwepheshe ezixhaswayo

Ikhonkco uswele ukudlalwa ividiyo kukuxhasa amathala eencwadi, API iDirectX 11. Olu phawu kunye amaxhoba amaninzi abathengi ezingayingozi uluvo ngokubanzi imveliso kunye chip GTX 480. Izinto eziluncedo ziquka inkxaso GPU Shader 5.0 kwaye kuqaliswa ubuchwepheshe bale mihla, unoxanduva ukusebenza ne-3D-virtualisation (3D Umbono, Blu Ray 3D kunye analogs zayo).

ezintsha kakhulu umdla wenze le nkampani Nvidia, ukungenisa kwifowuni iteknoloji 3D Kaka. Umenzi ithi ngoku abanini nga kuqhagamshelwa ikhadi yemizobo izixhobo ezintathu ukubonisa ividiyo kwaye tap ukujonga iindawo umfanekiso Vision 3D. Noko ke, ngokwendlela nokubuyekezwa zabamnini, obu bugcisa kusekude kakhulu ukusuka ofezekileyo, ngoko zonke ezi nguqu zintsha, yimizekeko enxulumene 3D, unobangela kuphela yokunganeliseki ngakwicala kubathengi. Ngapha koko, akukho namnye ofuna overpay kuba iteknoloji ongayi kusetyenziswa.

yemizobo Disclosure yokwakha namafutha

Kuba namafutha yemizobo GTX 480 iimpawu ukusebenza yonke le nkqubo zibaluleke kakhulu. Ubukhulu becala kufikwa apho CPU, leyo kufuneka kumaza ngentla GHz 3 ninxibe komgangatho omnye 4 iinkozo ngamnye. Nvidia umenzi ividiyo zabo zentengiso isebenzisa Intel Core I7 crystal (695 Extreme), ngokulandelelana, ukubhengezwa yevidiyo isakhono, umsebenzisi kufuneka ibe iyafumaneka kwi yokusebenza iprosesa efanayo.

RAM akukho PRETEGZY Noko ke, kwiirivyu zabo abasebenzisi bathi zokudlala ezininzi mihla kufuneka ubuncinane 8 GB. Njengoko for the hard drive, apha yonke into icacile ngaphandle naziphi na izimvo - nje okuqinileyo drive karhulumente SSD onokusinika yokusebenza endilisekileyo kwinkqubo yonke. Iingxaki zisenokuvela ubonelelo ngamandla. Iingcali bacebisa ukuba anikele ingqalelo ukuba amandla ifowuni (oko kufuneka ungabi ngaphantsi kwe-750 W), kwaye kukho umgca volt-12 enamandla, okanye ngenxa ukusilela umbane umnini inokungabi ividiyo.

Ummeli we imarike mobile

Kubalulekile ukuqaphela ukuba i-laptop usebenzisa ukulungiswa namafutha mifanekiso isekelwe phezu GTX 480. iinkcukacha chip akukho kwahluka kakhulu ukusuka isixhobo obubobu, adalwe iikhompyutha zobuqu. Okokuqala, umenzi kwanciphisa imali CUDA Iinkozo ukusuka iiyunithi 480 ukuya 352, nto leyo bachaphazeleka kakhulu intsebenzo yeli qonga mobile (ukulahleka malunga-20% uvavanyo uvavanyo zokwenziwa). Kwakhona, umenzi kuye kwanciphisa ibhasi bandwidth inkumbulo umda imilinganiselo yayo ezininzi yemizobo ophakathi-class card 256 ziintanda.

Ngokumalunga iteknoloji ababandakanyekayo, kubandakanywa inkxaso zeelayibrari mihla, kusekho ingaguqukanga apho. Ngokwendalo, uninzi labathengi abanomdla yokusebenza laptop kunokuba ukukwazi layo ukusebenza 3D. Ngoko ke, ezi nguqu ziye ziye zaphawulwa ukuze abasebenzisi abaninzi, yaye, ukugweba iimpendulo zabo, i iseti chip akunakwenzeka ukuba kutsala umdla kubathengi abaninzi.

swing ezinamaphiko

Emva kokungena imarike isizukulwana 5 amakhadi iigrafiki, abathandi abaninzi baye bagxalathelana ukuba ukwenza uthelekiso kunye neklasi ephezulu izixhobo zangaphambili, ngoko ke athandwa kakhulu eendaba lo mzekelo: GTX 480 vs GTX 570. Xa iimpendulo zabo, namafutha mifanekiso abanini ezininzi isizukulwana 4 aqinisekise abanye ukuba inkampani Nvidia awaqhubana nabo kakubi, ngokuba ukufundwa iimpawu zobugcisa zombini iifowuni kuya kuphumelela ukuba phantse ncam, kodwa iindleko yi amakhadi ezahlukeneyo (GTX 480 ibiza kakhulu).

Kuyamangalisa ukuba xa kuthelekiswa nemigaqo zokwenziwa, ikhadi yemizobo GTX 570 abapase kwi-flagship komsebenzi sizukulwana yesi-4. Imali phezu ngokutsha GTX 480 yokusebenza-olunzulu imidlalo onamandla, siyakwazi ukubona ukuba lo meko inguqulelo enkulu. Fans ngezicelo ezinjenge gta 5, Metro 2033, Ukungcola 2 kunye ummeli phezulu isizukulwana 4 uya kunandipha umdlalo izicwangciso ubuninzi ngezinga isakhelo eliphezulu. Kodwa ke abanini GTX 570 baya kuba nako ukwenza isicelo umgangatho eliphezulu kuphela.

Inyathelo ngokuthi zidale

Ngokumalunga luthelekiso GTX 480 vs GTX 650, isiphumo linakho ukuqikelelwa ngaphandle eqhuba naziphi na iimvavanyo. Makhe isizukulwana yokugqibela ummeli kwaye 6 Noko ke, oku kuthetha ukuba abakumgangatho ophakathi komdlalo, kwaye alinayo nayiphi na ithuba lokuba agoduke uloyiso kwiinkulu Nvidia 480 GTX. Kwiimvavanyo zokwenziwa ukubonisa ukusebenza GTX 650, nto leyo eya kuba ubuncinane 30-35% ngaphantsi koko yotshaba.

Noko ke, kule midlalo olutshintshatshintshayo resource-olunzulu, le meko mayilungiswe kancinane, ekuphazanyisweni ummeli isizukulwana-6 omabini kwinkumbulo kwaye kwi engundoqo. Ngokuqwalasela nokubuyekezwa abathanda, umsantsa yokusebenza kungancitshiswa ngama- ngesiqingatha. Nantso loo mntu nje, abethe kunye abanini GTX 480 yemizobo ikhadi overclocking umthamo lift nento eyenziwa Inkokeli, kwaye iphezulu kakhulu ngaphezu koko abameli kwicandelo zexabiso eliphantsi. Ukuba umthengi imiswe ukhetho onjalo (ukuthabatha GTX 480 okanye GTX 650), ummeli yokuqala Nvidia bhetele, nangona emdala njengotshaba yakhe iminyaka embalwa.

ungcono ezicacileyo

Isimanga livakala inokuba uthelekiso nowaye sizukulwana 4th kunye ummeli abakumgangatho ophakathi ukudlala imizuzu 700 ikhadi levidiyo series. Nangona kunjalo, kukho abantu lithemba abafuna ukubona luthelekiso iiyunithi ezimbini elinemveliso GTX 480 vs GTX 760. Kusengqiqweni ukucinga ukuba ngenxa yenguqu kwinkqubo entsha (ukusuka neenanometer-40 ukuya kuma-28), ummeli we-7-Series Kulula kakhulu ukuba yokucima i okhuphisana kuzo zonke iimvavanyo, zombini zokwenziwa kunye udlala.

Kwaye ukuba uthatha ingqalelo ukuba umenzi sele obekwe kwi chip GTX single 1152 760 CUDA iprosesa, ngoko onke amathandabuzo izakulahleka ngoko nangoko. Musa ukulibala ukuba ukususela-series 700 GPUs Nvidia wadlula njengomqobo nangokwasengqondweni 1000 MHz kwaye axhotyiswe yonke memory yemizobo amandla ubuncinane 2GB. Ngokukodwa kule kuthelekiswa, mmeli GTX 480 nje akukho ithuba lokuphumelela.

Ekuphetheni

Ebeka up on the High-Isiphelo ummeli isizukulwana 4-th, sinokwenza izigqibo eziliqela. Okokuqala, abanini esi sixhobo akwenzi ngqiqo ukutshintshela kwi ikhadi levidiyo 500-th ze-series 600. Noko ke, ukuba umthengi has ukhetho - thatha namafutha yemizobo isizukulwana wesi-7 okanye ukunika imiyalelo GTX 480, - ncomo ze abanini kunye ezininzi lweemvavanyo eziqhutyiweyo yi abathanda Siyaleza ukufumana ikhadi ividiyo 7 Series.
