While Jen-Hsun Huang, the CEO of NVIDIA himself admitted that this particular product is one of the company’s worst kept secret so far but nevertheless, here it is finally – the new NVIDIA Tegra 4 mobile processor. Revealed to the world during the company’s CES 2013 press conference earlier today, Tegra 4 is the first SoC processor to utilize ARM’s latest architecture – the Cortex A-15 – in its quad-core CPU although NVIDIA didn’t officially specify the CPU’s actual clock speed.

NVIDIA also increased the number of graphics core in Tegra 4’s GPU to 72 as opposed to Tegra 3’s 12. The new processor also marked the introduction of NVIDIA Computational Photography Architecture that aims to enhance mobile imaging experience by combining the processing power of GPU, CPU and image signal processor to the extent that it is able to deliver “Always-On HDR” camera technology.

Additionally, the new processor also supports 4G LTE via the optional NVIDIA Icera i500 processor and not to forget, 4K video playback. With the help of its low-powered fifth core in its CPU and PRISM 2 Display Technology that reduces the power used by a display’s backlight, NVIDIA claims that Tegra 4 consumes up to 45-percent less power than Tegra 3.

NVIDIA is still mum of Tegra 4’s actual availability in the market but at the very least, we do know one product that is already equipped with the new processor – NVIDIA’s own Project Shield handheld gaming system.
