The budget Tegra 4i is part Tegra 3, part Tegra 4 system chip, which will be used in mid-range devices. Unlike its bigger sibling (Tegra 4), the Tegra 4i comes with an LTE-Advanced modem on board, but sports fewer GPU cores compared to the Tegra 4. However, the 4i is more power-efficient due to its updated version of the quad-core Cortex-A9 CPU in comparison with the more powerful Cortex-A15, which is used in Tegra 4.
Nvidia Tegra 5, a.k.a. Logan, will not come with LTE modem inside. Nevertheless, the Icera i500 LTE modem, which Nvidia provides with the Tegra 4i, is certified and suitable for the Tegra 5 as well. The Tegra 5 will allegedly have one of the fastest GPUs around – the 192-core GPU Kepler, and will be a direct rival to Qualcomm's Adreno 400, which is also expected to be unveiled next year. Interestingly, Jen-Hsun Huang also admitted that customers will be delighted by the manufacturer that will produce these first Tegra 4i and Tegra 5 devices.
