NVIDIA GeForce GTX 480: Ukucaciswa, ukubuyekezwa, ukubuyekeza

Lapho zokusebenza fan khudlwana ashukumisayo kukhona enesifiso sokujabulela ukudlula eseyintsha esilandelayo emhlabeni umdlalo, ngeke icabange ukuthi kungenzeka isiqophi ikhadi lalo ukufakwa iyunithi uhlelo. Phela, njengoba umkhuba imibukiso, iyunithi isabelomali kanye kokuqala amakilasi okudlalekayo nzima nakakhulu ukubhekana imisebenzi. Phuma lapha - ukuthola GTX High-End ihluzo ikhadi 480 ekilasini futhi 5-10 iminyaka ukukhohlwa mayelana nezinkinga ezihlobene okusithiyayo ku amathoyizi isisetshenziswa khudlwana. Izici, ukubuyekezwa, ukubuyekezwa kanye ukuqhathanisa umkhiqizo esincintisana ukusiza amakhasimende ukwenza ukukhetha okufanele.

izici lobuchwepheshe

Chip igama lekhodi Fermi wokugubha futhi GF100 wakhiwa kusetshenziswa 40-nanometer ubuchwepheshe eyenza umkhiqizi hhayi kuphela ihlanganise transistors okwengeziwe chip (3.2 billion), kanye nedivayisi amageyimu futhi ukunciphisa amandla ukusetshenziswa GeForce GTX 480. Yokuxhumana ukushisa ingeqi 250 Watts, ukuthi okwesikhathi High-End kuyinto inkomba okukhulu. Isiqophi adaptha has amaqoqo ezine kucutshungulwa ingcaca ekusakazeni idatha has 15 multiprocessors futhi 480 CUDA izikhwebu. Ihluzo processor, njengoba eyakhelwe, is clocked at 700 MHz. inkumbulo Isiqophi chips kwakheka kwi GDDR5, lunamandla 1.5 GB futhi usebenza ku-384-bit ibhasi. Ngempumelelo inkumbulo imvamisa kuba 3696 MHz.

ubuchwepheshe asekelwe

Isixhumanisi buthaka nokudlala bevidiyo ukusekela imitapo,-API IDirectX 11. Lesi sici futhi nqoba ningi onakala abathengi ezingase zisetshenziselwe ukuba umqondo jikelele imikhiqizo nge chip GTX 480. Izinzuzo zibandakanya i-GPU Shader 5.0 kanye nokwethulwa ubuchwepheshe banamuhla ngokunenzuzo, obhekene ukusebenza 3D-virtualisation (3D Vision, Blu-Ray 3D analogs yalo).

emisha ngempela ezithakazelisayo ukwenze inkampani Nvidia, ethula ku idivayisi 3D Kaka ubuchwepheshe. Umenzi uthi manje abanikazi kungenziwa exhunywe kwi-ikhadi ihluzo amadivayisi ezintathu ukubonisa ividiyo bese uthinta ukubuka izithombe izibuko 3D Vision. Nokho, nahlulele by ukubuyekezwa abanikazi, lobu buchwepheshe namanje neze, ngakho zonke lezi ezintsha, okuyinto zihlobene 3D, kuphela imbangela ukunganeliseki phezu ingxenye abathengi. Phela, akekho ofuna overpay okwesikhathi ubuchwepheshe ngeke isetshenziswe.

Ukudalula ihluzo isakhiwo namafutha

Ukuze ihluzo namafutha GTX 480 ukusebenza izici lonke uhlelo kuyadingeka. Ngokuyinhloko kuziwa CPU, okumele libe imvamisa ngenhla 3 GHz futhi nigqoke platform eyodwa 4 izikhwebu ngabanye. Nvidia nomkhiqizi kuvidiyo yabo yokukhangisa isebenzisa Intel Core I7 crystal (695 Extreme), ngokulandelana, ngokuba ukudalulwa isiqophi ezingaba, umsebenzisi kufanele libe khona phezu processor ukusebenza efanayo.

RAM kungekho PRETEGZY Nokho, phakathi izibuyekezo zabo abasebenzisi zithi amathoyizi eziningi zanamuhla kudingeka okungenani ube 8 GB. Ngokuqondene hard drive, lapha yonke into icacile ngaphandle imibono - nje okuqinile isimo drive SSD anganikeza ukusebenza ehloniphekile lonke uhlelo. Izinkinga zingase ziphakame ne kwamandla. Ochwepheshe batusa ukuba banake hhayi amandla idivayisi (kufanele kube hhayi ngaphansi kuka 750 W), futhi ukuba khona enamandla 12 engama-volt angu umugqa, noma ngenxa yokwehluleka ka ugesi umnikazi ungalahlekelwa vidiyo.

Ummeleli we emakethe mobile

Kuyaphawuleka ukuthi i-laptop isebenzisa Ushintshe ihluzo namafutha esekelwe GTX 480. chip Ukucaciswa kuba ngokuphongoza idivayisi leyehlukene, adalwe computer. Okokuqala, umenzi encishisiwe lemali CUDA izikhwebu kusuka amayunithi 480 kuya 352, okuyinto kakhulu abathintekayo kusebenta jikelele yesikhulumi mobile (ukulahlekelwa ngu-20% zokwenziwa test ukuhlolwa). Futhi, umenzi kuye kwanciphisa inkumbulo ibhasi komkhawulokudonsa ngokukhawulela ejwayelekile yayo ngoba iningi ihluzo ongaswele ikhadi 256 izingcezu.

Ngokuphathelene ubuchwepheshe abathintekayo, okuhlanganisa ukusekela imitapo zanamuhla, kunenhlangano namanje ayizange ithuthuke. Ngokwemvelo, iningi abathengi unesithakazelo laptop ukusebenza kunokuba ikhono lawo ukusebenza 3D. Ngakho-ke, lezi zinguquko kuye kwaqashelwa kubasebenzisi eziningi, futhi, nahlulele kusukela izimpendulo zabo, isethi chip akunakwenzeka ukuba zidonse ukunaka kwanoma abathengi abaningi.

swing ezinamaphiko

Ngemuva kokufaka emakethe isizukulwane 5th ihluzo amakhadi, Baningi abantu abathanda baye bagijimela kubo iziqhathanise isigaba phezulu amadivayisi langaphambilini, ngakho ethandwa kakhulu abezindaba iyona siqhathaniso: GTX 480 vs GTX 570. Ngo izimpendulo zabo, abanikazi abaningi ihluzo namafutha yesizukulwane esingu-4 aqinisekise abanye ukuthi inkampani Nvidia asingatha ngayo indaba yabo ngendlela engafanele, ngoba ucwaningo izici lobuchwepheshe kokubili kumadivayisi Kuyophumela ethubeni ukuthi basuke kucishe, kodwa izindleko amakhadi ahlukene (GTX 480 kuyabiza).

Kuyamangalisa ukuthi uma iqhathaniswa namabhentshimakhi zokwenziwa, ihluzo ikhadi GTX 570 maqembu phezu iwuhlelo nokusebenza yesizukulwane esingu-4. Ukusetshenziswa kwesabelo-sekubuyeketwa GTX 480 ukusebenza khudlwana imidlalo ashukumisayo, singaphetha ngokuthi isimo kwenzeka izinguquko ezinkulu. Abalandeli kwezicelo ezifana GTA 5, Metro 2033, Ukungcola 2 ne omele phezulu yesizukulwane esingu-4 uzokwazi ukujabulela umdlalo izilungiselelo esiphezulu nge okusezingeni eliphezulu lozimele. Kodwa abanikazi GTX 570 bazokwazi ukusebenzisa isicelo nge eliphezulu kakhulu kuphela.

Isinyathelo ngokusebenzisa isizukulwane

Ngokuphathelene Ukuqhathaniswa GTX 480 vs GTX 650, umphumela kungaba wabikezela ngaphandle kokuqhuba noma yiluphi uvivinyo. Ake Nokho, isizukulwane omele futhi 6th zokugcina, ibhekisela abasesigabeni esiphakathi yomdlalo, futhi akanayo ithuba ongazihlwitha ukunqoba kusukela umholi Nvidia 480 GTX. Ngo zokwenziwa ukuhlolwa khombisa ukusebenza GTX 650, okuzoba okungenani 30-35% leliphasi kunaleyo lesitha.

Nokho, e-ashukumisayo imidlalo isisetshenziswa khudlwana, isimo ezingelapheka kancane, breaking up ummeleli isizukulwane 6th kokubili inkumbulo futhi umnyombo. Ukwahlulela ngokubukeka ukubuyekezwa abathanda, igebe ukusebenza zingancishiswa ngesigamu. Yilokho nje akekho ekukhathaza futhi abanikazi GTX 480 ihluzo ikhadi Overclocking lift umthamo kanye bezikhali umholi, futhi siphezulu kunamanye ukuthi abamele kwetindlu letibita kancane ingxenye. Uma umthengi ibhekene isinqumo esinjalo (ukuthatha GTX 480 noma GTX 650), ummeleli wokuqala Nvidia akukhetha, yize-ke omdala kunawe ophikisana naye iminyaka embalwa.

bokuphakama esobala

Okuxakayo kungase bheka ukuqhathanisa iwuhlelo yesizukulwane esingu-4 ummeleli zabantu abasesigabeni esiphakathi zaziba edlala imizuzu 700 chungechunge isiqophi ikhadi. Nokho, kukhona abantu yenza ngokuphelelwa yithemba abafuna ukubona ngokuqhathanisa amayunithi ezimbili elikhiqizayo GTX 480 vs GTX 760. Kunengqondo ukuphetha ngokuthi ngenxa kwathatha inqubo entsha (kusuka nanometer 40 kuya ku-28), ummeleli we-7-Series Kulula kakhulu ukundlula esincintisana zonke izivivinyo, kokubili zokwenziwa amageyimu.

Futhi uma acabangele ukuthi umenzi aye wayibekela olulodwa chip GTX 760 1152 CUDA processor ke konke ukungabaza uzonyamalala ngokushesha. Ungakhohlwa ukuthi kusukela 700-uchungechunge GPUs Nvidia lidlule umgoqo ngokwengqondo 1000 MHz futhi ifakwe wonke amandla ihluzo inkumbulo okungenani 2GB. Engavamile kule ukuqhathanisa, ummeleli GTX 480 nhlobo ithuba lokuwina.

Ekuphetheni

Efingqa Phezulu-End isizukulwane 4-th ummeleli, singaqondile, singafinyelela eziphethweni eziningana. Okokuqala, abanikazi kule divayisi akwenzi mqondo ukushintshela ividiyo ikhadi 500-th futhi 600-chungechunge. Nokho, uma umthengi has ukukhetha - thatha ihluzo namafutha isizukulwane 7th noma makudle the GTX 480, - Izibuyekezo wabanikazi futhi eziningi ukuhlolwa kwenziwe abathanda ukuncoma ukuthola ikhadi isiqophi 7 Series.
