Update: Our full review is now live!
It's been 22 days since we saw the Tegra 2 packing LG Optimus 2X at CES, and just moments ago the device arrived at our doorsteps ready for a thorough reviewing. It's out of the box and charging now, ready to enter our battery life tests, but before that we managed to grab a bunch of photos and a few quick benchmarks.
First off, our model is European-spec and likewise came with a Type-C power adapter. Luckily we've got tons of microUSB chargers laying around. Our unit's packaging is definitely not final, as it came in just a black box with the accessories, but that's hardly an issue, what we're interested in is some Tegra 2 performance. Physical feel and appearance is almost exactly how we left it at CES.
Some quick benchmarks show Tegra 2 performance definitely leading in the browser area. Note that the Optimus 2X is shipping with Android 2.2.1. Gingerbread (2.3) was launched on Samsung's Hummingbird so it'll take a little while to port it over to NVIDIA's hardware. Honeycomb (3.0), on the other hand, will launch on Tegra 2 hardware once more.
Note that most of the performance advantage NVIDIA currently holds in these tests is between 12 - 25%. This implies that Qualcomm's 1.2GHz dual-core Snapdragon due out later this year could be performance competitive with NVIDIA's dual-core Cortex A9 Tegra 2. We still have a lot more benchmarking to do in order to properly characterize and understand NVIDIA's Tegra 2 performance in a smartphone however.
Linpack performance is a bit behind the latest from Qualcomm, but that's more telling of FPU performance and cache bandwidth than most real world smartphone apps:
We've got a lot more to run on the LG Optimus 2X, but so far it looks impressively speedy, just as expected.
Update: We've taken our usual video samples from the Optimus 2X, and uploaded them to YouTube and our own servers in a big (147 MB) zip. Full analysis will come with our larger review.

Those synthetic benchmarks are entertaining if only for nostalgia's sake. Compare some of those numbers to your first computer.jeffbui - Thursday, January 27, 2011 - link

Oh god I was using a pentium mmx 233 till 2004 and now it's surpassed by a phone chip.DanNeely - Thursday, January 27, 2011 - link
I didn't realize any of these benchmarks had been ported to Motorola 6809 architecture. :)The Hardcard - Friday, January 28, 2011 - link
Hey, you had a Coco too! I still have a Coco 3 in a box. Maybe I'll dig it out and run Linpack on it. How far behind a free feature phone do you think it is?Zokudu - Thursday, January 27, 2011 - link
Why does the system information list 1 core? I thought the big thing about Tegra 2 was that it was a dual core in addition to improved graphics capability.Brian Klug - Thursday, January 27, 2011 - link
I'm glad someone else saw that too ;)Quadrant only shows one core for some reason, but Tegra 2 is indeed dual core in this phone. Just one of the many things we're going to find out going forward is what's multithreaded and what isn't.

what carrier/frequencies does it have? I want it for T-Mobile!!BryanC - Thursday, January 27, 2011 - link
Your linpack binary doesn't appear to be parallelized - I'd expect linpack to scale well with the number of cores.Is your linpack written in Java? How about the version you run on the iPhone?

We're using Linpack for Android: greenecomputing.com/apps/linpack/It's currently likely single threaded, but we're undergoing a learning process about what is and isn't mulithreaded in Android through Dalvik. We don't have a version of Linpack on the iPhone ;)
