Tegra 4i
I'm looking forward to the Tegra 4i, (which is more related to the Tegra 3 than the Tegra 4; The Tegra 4i has similar QuadCore plus the lite CPU to the Tegra 4, but they're ~2GHz Cortex A9 cores; the 4i manages to lose 12 graphic cores - down to just 60...... something else needs that tiny space on the silicon)
So why do I look forward to the 4i?, well it's explained as featuring an British designed Icera software defined radio as part of the SoC single chip package.
SDR History: Icera made a '450 Espresso' HSPA+ modem in 2011 thruput-28MBPS, an Icera 410 LTE Modem thruput-50MBPS (which gained AT&T LTE certification) in 2012, now this upcoming QuadCore Tegra 4i SDR will debut at 100MBPS and will be upgradeable to around 150MBPS LTE/4G.
The Tegra 4i is is expected to power mid-range Android smartphones manufactured in 2014
