Nvidia have unveiled the Nvidia Tegra 4i which is their very latest mobile processor that brings amazing performance in a compact form. In essence it's a slightly more affordable and compact version of the Tegra 4 processor that Nvidia unveiled at the start of this year.
Nvidia's Tegra 4 chip introduced a second generation battery saving core which improved battery life by up to 45 per cent. This feat was achieved thanks to the inclusion of a 5th low-consumption core which is used when the mobile doesn't require the full power of Nvidia's quad-core chip.
The good news is that the same technology has been incorporated into the Tegra 4i giving it amazing performance and excellent battery performance. The Tegra 4i mobile processor includes the very latest ARM CPU, the R4 Cortex-A9 , which is a quad-core chip running at 2.3 Ghz.
While, Nvidia have also included 60 custom Nvidia GPU cores offering five times the performance Nvidia's Tegra 3 chip. The new chip also enables mobile devices to take HDR photographs including stunning Panoramic HDR shots.
Nvidia's Tegra 4i also comes with an integrated i500 4G LTE chip which is software controlled meaning it can re-programmed to support different frequencies. This is one area where the Tegra 4i has the edge on the Tegra 4 which only optionally includes support for 4G.
Overall the Tegra 4 is still the daddy when it comes to Nvidia's processors. However, the performance of the Tegra 4i is only just below it's bigger brother.
The strength of the Tegra 4i is its compact size which enables it to fit inside smaller handsets, while it'll also be significantly cheaper than the Tegra 4. The end result is that more power can brought to more mid-range smartphones without increasing their costs significantly.
We expect a number of Tegra 4i powered smartphones to be unveiled at this years Mobile World Congress. The event starts at the end of the month in Barcelona and 3G will be bringing you all the news as it breaks.
