Vediamo subito le caratteristiche tecniche di questo nuovo gioiellino:GeForce GPU with 72 custom cores
- CPU Quad-Core con architettura Cortex A-15
- GPU GeForce a 72 Core
- Struttura 4+1 con core aggiuntivo per risparmio energetico di seconda generazione
- PRISM 2 per ridurre l’uso della retroilluminazione
- Computational Photography Engine per prestazioni fotografiche senza precedenti
- Supporto alle reti LTE opzionale tramite il chipset Icera i500
- Supporto ai video in risoluzione 4K (ultra-HD)
Grazie a questo nuovo processore e la sua GPU avremo prestazioni grafiche mai viste prima su dispositivi mobili, con una grafica che si avvicinerà ancora di più a quella che troviamo su consolle come Xbox 360 e PlayStation 3. Il Tegra4 inoltre consuma il 45% in meno rispetto al Tegra3 nell’utilizzo comune, e permetterà fino a 14 ore di riproduzione di video HD sui telefoni.
Va anche citata la nuova struttura computazionale fotografica che ci permetterà praticamente di scattare e processare istantaneamente un immagine con HDR.
Ecco il comunicato stampa ufficiale rilasciato da Nvidia:
LAS VEGAS, NV–(Marketwire – Jan 7, 2013) – CES — NVIDIA today introduced NVIDIA®Tegra® 4, the world’s fastest mobile processor, with record-setting performance and battery life to flawlessly power smartphones and tablets, gaming devices, auto infotainment and navigation systems, and PCs.
Tegra 4 offers exceptional graphics processing, with lightning-fast web browsing, stunning visuals and new camera capabilities through computational photography.
Previously codenamed “Wayne,” Tegra 4 features 72 custom NVIDIA GeForce™ GPUcores — or six times the GPU horsepower of Tegra 3 — which deliver more realistic gaming experiences and higher resolution displays. It includes the first quad-core application of ARM’s most advanced CPU core, the Cortex-A15, which delivers 2.6x faster web browsing and breakthrough performance for apps.
Tegra 4 also enables worldwide 4G LTE voice and data support through an optional chipset, the fifth-generation NVIDIA Icera® i500 processor. More efficient and 40 percent the size of conventional modems, i500 delivers four times the processing capability of its predecessor.
“Tegra 4 provides enormous processing power and efficiency to power smartphones and tablets, gaming devices, auto systems and PCs,” said Phil Carmack, senior vice president of the Tegra business at NVIDIA. “Its new capabilities, particularly in the area of computational photography, will help improve a whole range of existing products and lead to the creation of exciting new ones.”
Computational Photography Capability
Among the Tegra 4 processor’s breakthroughs is its Computational Photography Architecture, which automatically delivers high dynamic range (HDR) photos and video by fusing together the processing power of the GPU, CPU and the camera’s image-signal processor.Its HDR capability captures images, including those taken with a flash, the way they are seen by the human eye — with detail in both bright and dark areas.
Unprecedented Power Efficiency
Designed for maximum energy efficiency, Tegra 4 includes a second-generation battery saver core for low power during standard use, and PRISM 2 Display technology to reduce backlight power while delivering superior visuals.Tegra 4 consumes up to 45 percent less power than its predecessor, Tegra 3, in common use cases. And it enables up to 14 hours of HD video playback on phones.
Purtroppo non sappiamo ancora quali produttori adotteranno questo chipset e in quali telefoni sarà montato, sicura invece la sua presenza su SHIELD, la nuova consolle portatile realizzata da Nvidia.
