It's a shame when phones feel outdated even as they hit the market, but that's sadly what happened with the original Grand X. However, as you may have heard a few hours ago, the handset's just had a healthy revamp. The spec-bumped version is called the Grand X IN -- it's due out next month and we've just had a chance to run some early benchmarks to test the performance of its vanilla Android 4 OS and new Intel engine. Among a range of improvements, including an 8-megapixel camera with burst mode (instead of the Grand X's dowdy five with no burst) and 1GB of RAM (instead of 512MB), the biggest change is that processor: out goes the old NVIDIA Tegra 2 and in comes a Medfield Z2460. Yep, that's the exact same chip we've seen put to good effect in the Orange San Diego, but how does it fare in this device? Click past the break for a head-to-head comparison with the San Diego, which is cheaper but slightly less well-built (and still running Gingerbread), and the Galaxy Nexus, which costs more but comes with a far better display.
