The good news is that the Tegra 3 international version, model number PJ46100, has just cleared through the FCC, bringing it closer to launch. If you are disappointed that the LTE version is dual-core, it should be possible to import the quad-core and use it on AT&T’s 3G frequencies if HSPA+ is fast enough for you. However, I would recommend waiting until full benchmarks and real-world testing can determine whether the Tegra 3 is indeed faster than the Snapdragon S4, at least for your uses.
Tell us what you think in the comments below. Would you prefer the quad-core with slower connection speeds, or the dual-core with LTE?
