Windows Rt ARM

The Tegra 4, the latest mobile processor of NVIDIA, was launched recently at a Consumer Electronics Show 2013 event held in Las Vega, according to a report. The new processor enhances the capabilities of its previous versions. The ULP GeForce graphics processor features 72 GPU cores along with four Cortex A-15 cores from ARM, making it the first A15 chipset with a quad-core. The chip also features the return of the low power core.

Although 4G LTE connectivity was featured on the slideshow, it does not appear to be built into the chipset. This indicates that it will need another chip, which will affect its battery life. In comparison, the chipsets of Qualcomm already integrates the feature.

A demonstration during the event showed a tablet using the Tegra 4 chipset outperforming the Nexus 10 in a webpage loading test. The Nexus 10 features an Exynos 5 processor with a pair of Cortex A15 cores. In comparison, the Tegra 4 has four A15 cores. The speed of the new processor was emphasized during the event as it also indicated that it was even faster compared to the A6X chip of the Apple iPad 4.

The chipset also features the NVIDIA Computational Photography Engine that allows a phone to record two images and immediately produce an HDR image in just one shot. This particular photo engine is supposedly capable of creating HDR images ten times faster compared to the one used on the Apple iPhone 5. This means HDR shots can be made in only 0.2 seconds. The photo engine is also capable of producing HDR videos, which may open up other features in the future.

A prototype tablet using the Tegra 4 chipset was able to record an HDR video. Since the tablet had a Windows logo, it may be an upcoming Windows RT device that features the new NVIDIA processor. However it was noted that the tablet was supposedly using an Android application, which has made it uncertain which platform it will be using if it reaches the market.
