Ukufika UNvidia Tegra 4 Bekuyimfihlo evulekile, yize inkampani ibingakaluqinisekisi usuku oluqondile ezokwethula ngalo le-SoC entsha emphakathini. Hhayi-ke, lokhu kwenzeke phakathi nengqungquthela yabezindaba ye-Nvidia kulo mbukiso obanjelwe e-Las Vegas futhi, ngakho-ke, imininingwane eminingana yokubheja kwayo konyaka ka-2013 isivele yaziwa.
Njengoba sekuvele siyamemezela ngaleso sikhathi Android AyudaLe processor entsha -ezobe isivele isebenzisana noxhumo lwe-LTE uma kudingekile- ihlose ukunikeza umuzwa ongcono kakhulu wesithombe ngaphandle kokukhohlwa ukusebenza okuhle kwezinye izigaba. Ngakho-ke, mhlawumbe into entsha ephawuleka kakhulu yileya ngaphakathi i-GPU (ikhadi lemifanekiso) inama-cores angama-72, ngakho-ke kulindelekile ukuthi ukusebenza kwayo kuhle ngempela, ngokwesibonelo, imidlalo. Ngokusho kukaNvidia uqobo, le ngxenye ifika izikhathi ezi-6 ngokushesha kuneTegra 3 futhi, ngaphezu kwalokho, inikeza ukusekelwa kwe-Direct3D 11 kanye ne-OpenGL 4.0 APIs.
Eminye imininingwane yeTegra 4 entsha imi kanje:
- Ubuchwepheshe bokukhiqiza: 28 nm
- Izakhiwo I-ARM Cortex-A15
- Kuyimodeli ye-quad-core (I-Quad Core +)
- Ikhiqizwa ubuchwepheshe be-TSMC kanye ne-HPL
- Ama-cores amane okusebenza asebenza kuwo I-1,9 GHz, kuyilapho umnyombo wemisebenzi engadingi kakhulu futhi i-Cortex-A15
- Uhlobo lwenkumbulo ekabili i-DDR3L, i-LP DDR2, i-LP DDR3
- Iyahambisana namavidiyo I-1440p ephelele kanye nokusheshisa kwe-VP8
- Ubukhulu bokulungiswa kokungu-2.560 x 1.600, obuhambisana ne-HDMI (Isivinini esikhulu) kanye nesibonisi esikabili
- Isekela izimbobo USB 3.0
Njengoba ubona, intuthuko enhle, eyisisekelo, egcina lezo esezivele zifakiwe i-Tegra 3 kodwa ezivele zavela kakhulu. Ngaphandle kokungabaza, le modeli ingaba ukwethulwa okubaluleke kakhulu kusenesikhathi ngokwezithombe ezinezinhlangothi ezintathu futhi, ngaphezu kwalokho, lokhu kuhambisana nokwethulwa Project Shield.
Ukukhishwa okumangazayo: Project Shield
Lesi isimanga uNvidia ayesibekele i-CES. I-CEO yenkampani, UJen-Hsun Huang, ngemva kokutshela izindaba ze-Tegra 4, unogwaja omhlophe wakhishwa esigqokweni sakhe: a ikhonsoli ephathwayo ehlanganisa i-Android Jelly Bean ingalungiswanga nokuthi, ngaphezu kwalokho, izoba ne-Tegra 4 SoC ngaphakathi. Okusho ukuthi, izoba umxhwele ekusebenzeni kwayo kanye nekhwalithi yesithombe. Ngokungangabazeki, into entsha emangazayo nokuthi, ngaphezu kwalokho, izosekelwa I-TegraZone, isigaba le nkampani enaso semidlalo edalwe ngokukhethekile ukusizakala ngamaphrosesa ayo.
Njengoba ubona esithombeni esidlule, ine-a Isikrini se-intshi se-5 ngesilawuli "kuphekhi" onomklamo ofana negobolondo ovula futhi avale ... uhlobo lweNintendo DS, kodwa ngezinye imigqa. Isekela izithombe ze-4K futhi ine Ukukhishwa kwe-HDMI ukuvumela i-Project Shield ukuthi ixhunywe kumathelevishini.
Iphaneli elifakiwe linikeza a Isixazululo esingu-720p (enokuminyana okungu-296 dpi) futhi inikeza ikhwalithi yesithombe enhle ngempela. Uma kuziwa ekuxhumekeni, ukusekelwa kwe I-WiFi ne-Bluetooth, ngaphandle kokuqinisekiswa kwe-DLNA kodwa, ngokuvamile, isuka emdlalweni. Ngokungangabazeki umkhiqizo ozonikeza okuningi ukukhuluma ngakho futhi lokho kakade kuyinto yokufisa okungaphezu kweyodwa.
Izinsuku zokukhishwa aziqinisekiswanga nge-Tegra 4 noma i-Project Shield, kodwa i-imeyili evela ku-Nvidia ngokwayo ibonisa lokho. ngesinye isikhathi kuQ2 yomibili imikhiqizo ingase idayiswe kulo nyaka. Mayelana ne-SoC, abekho abakhiqizi ababonisiwe ukuthi bazoyifaka kumamodeli abo. Izindaba ezinhle ezivela ku-Nvidia eziqinisekisa ukuzibophezela kwayo okuqinile emhlabeni we-Android.
