The One X (left) next to last year's HTC Sensation This extra core is limited to just 500 MHz, but uses less power than any one of the four 1.5 GHz ARM Cortex-A9 cores so the main processing unit offloads low intensity tasks (such as music playing with the display off) to the companion core to save battery. Tegra 3 also comes with the touted "4-plus-1" core configuration that sees the system-on-a-chip outfitted with a fifth low-power "companion core".
Just on the RAM, one of the under-the-hood features that often gets overlooked is the fact that Tegra 3 raises the 32-bit single-channel LPDDR2 from 600 MHz to 1066 MHz for increased I/O speed. One of the big ones is that the HTC One X is the first smartphone to ship with a quad-core Tegra 3 chipset under the hood: it runs at 1.5 GHz across all four ARM Cortex-A9 cores, comes with the improved 12-core ULP GeForce GPU and 1 GB of RAM.
