NVIDIA introduced Tegra 4 processor at CES 2013. It is World’s Fastest Mobile Processor according to NVIDIA. Tegra 4 features quad-core processor along with a fifth low power core to save battery life. This new processor has 72 GPU cores, this is 6 times graphics processing power of existing Tegra 3 processor.
Tegra 4 is build on 28nm process which helps it consume 45% less power than Tegra 3 processor and provides upto 14 hours of HD video playback on mobile phones. The processor supports maximum frequency of 1.9 GHz. We have to wait and see at what frequencies it will be clocked inside mobile phones.
NVIDIA however failed to integrate LTE chip in the new processor just as in previous generation Tegra 3 processors. So smartphones and tablets with Tegra 4 inside will require an additional cellular modem.
“Computational Photography Engine” was also demonstrated at this announcement. This significantly reduces the time for camera related functions, and improves HDR photography. Tegra 4 can do real time HDR previews and apply the effect as a filter.
There is no word yet on price and availability of Tegra 4 processor. NVIDIA has used this Tegra 4 at the heart of its Project Shield, a handheld console, which was also introduced at CES 2013.
