In 2011 it felt a bit like HTC was playing catch-up with Samsung. They failed to release the HTC Sensation before the Samsung Galaxy S II was launched, and while the device was a solid dual-core performer it never reached the heights and success of the Galaxy. They followed up the Sensation with the likes of the Rezound, Sensation XE and XL but again the devices were not compelling enough to steal the market away from Samsung.
However, we're in 2012 now and it's a new era for HTC with their One Series devices. Along with the smaller One S and mid-range One V, HTC has grand plans to reclaim the high-end market with the HTC One X; brand new design, powerful specifications and a full-featured camera all make the device, on paper, look like a compelling purchase. Not to mention that it's packing the latest Android 4.0 with HTC's revamped Sense 4.0 UI.
The HTC One X is already available on several phone carriers worldwide as a top-tier device, and will be launching in the United States in early May (albeit with slightly different specifications). HTC manages a couple of "firsts" for this device.
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. 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.
