Greetings from New York! LG showed off the Optimus G today, their new monster of a phone. If you haven’t heard, it’s the first phone with a 1.5Ghz quad-core Snapdragon S4 Pro processor. Qualcomm's dual-core chips can hold their own against the quad-core Nvidia Tegra 3, so this should be one of the fastest phones available. It’s also one of the first phones to have a next-gen Adreno 320 GPU, which, again, means it should be really fast.
I got to play around with one for a few minutes, and yes, the real world performance lives up to the specs. Everything is blazingly fast, and animations are buttery-smooth.
