In many ways, the smartphone platform has evolved following the same kinds of steps we saw in the early days of the PC—lots of different software and hardware platforms, rapidly changing lead players, faster and faster platform update cadence, the slow emergence of obvious majority leaders. Anand and I have talked extensively about just how striking the similarities are between the PC evolution and the current mobile one, but one of the striking differences is just how much faster that evolution is happening in the mobile space. The reason is simple—nearly all the hard lessons have already been learned in the previous PC evolution, it's just a matter of porting that knowledge to mobile under a different set of constraints.
2011 is going to be a year dominated by multi-core smartphone launches, but there always has to be a first. So just like that, we have our first example of said category of smartphone, the LG Optimus 2X, with Nvidia's dual-core 1 GHz Tegra 2 AP20H at its heart. The Optimus 2X (simply the 2X henceforth) hasn't changed much since we saw it at CES—the hardware is aesthetically the same, and software at first glance is the same as well. We weren't able to publish benchmarks at that time purely because LG hadn't finalized the software build on that test hardware, but we definitely can do so now.
First off are the hardware specs. There's a version of the 2X already shipping on South Korea Telecom which is similar but not identical to the version we were sampled—what we're reviewing is the LG PP990 rather than the SU660. You can look at the specs of that Korean version and compare yourself, but the differences boil down to a few things. The South Korean version ships with 16 GB of internal storage compared to 8 GB like ours, Xenon versus LED flash, likely a different build of Android (more on that later), and a physically different set of Android buttons. The Korean version also has T-DMB for mobile TV. LG hasn't officially announced what carrier the 2X will launch with stateside, nor has it been specific about what UMTS or GSM bands that final version will work with, I'd expect that announcement to happen at MWC. Needless to say, I was surprised that the 2X immediately hopped on HSPA when I inserted my personal AT&T SIM. Regardless, just know that what we're reviewing here is something between the international model and what will be launched in the US. The 2X will launch running Android 2.2.1 and is already slated to move to Android 2.3 at some time in the future.
