Introducing the Sony VAIO Z2

Users who want everything out of their notebook, no matter how ridiculous the demands, are probably more than at least a little curious about Sony's new VAIO Z2. There's good reason to be: this 13.1" ultrabook features a stunning 1080p screen, a secondary battery slice that nearly doubles running time off the mains, and an external dock box that features an optical drive, additional connectivity, and a dedicated GPU that can actually be used to power the notebook's internal screen. The VAIO Z2 has a lot going for it, but is it worth the heavy price tag?

Sony's website lists this unit under the same old Z-series heading, but you'll remember last generation's Z-series notebooks used Arrandale CPUs and packed an optical drive and GPU into the main chassis. The Z2 also technically wouldn't qualify as an ultrabook with a starting price north of $1,600, but the design and build quality is basically in line with Intel's specification (other than the full power CPU). Sony just also happens to include a wealth of extras in the box with it to shore up any deficiencies the primary system might have.

It's fairly obvious Sony is gunning for the premium ultraportable market with the VAIO Z2, much as they did with its predecessors. The Z2 is slim and light, but unlike other ultrabooks, Sony elected to use a full-wattage Intel Sandy Bridge processor in the form of the Core i7 2620M, a dual-core processor that runs at a 2.7GHz nominal clock but turbos up to 3.2GHz on both cores or 3.5GHz on a single core. They pair it with 4GB of dual channel DDR3-1333, and you can order the Z2 with up to 8GB, but buyer beware: the memory is soldered on to the motherboard. If you want more than the standard 4GB of DDR3, you'd better order it from the get go because you won't be able to upgrade it later.

Also not upgradable but still appreciated is the SSD. Information about the controller used is not forthcoming, but the individual drives are running on SATA 3Gbps instead of SATA 6Gbps, and then data is striped between two channels in RAID 0. It's a decision of questionable value to the end user; the HM67 mobile chipset is capable of supporting a SATA 6Gbps SSD, so the only real benefit here is the pair of SSD controllers theoretically improving overall throughput.

The rest of the notebook on its own is business as usual excepting the stellar 1080p 13.1" screen. It's definitely a TN panel, but as you'll see later it's among the best notebook screens we've ever tested. The 1080p screen is an upgrade, but even the bottom rung model of Z2 still comes with a 900p screen bog standard, a far cry from the poor quality 768p screens other manufacturers are using.

While sheet batteries are nothing new and the one available for the Z2 does exactly what it was intended for, the docking unit is another matter entirely. Sony dubs it the Power Media Dock, and it offers something most notebook users have been clamoring for: a discrete graphics upgrade. Since the Z2 itself is too small to house a discrete GPU, the Power Media Dock features an AMD Radeon HD 6650M with 1GB of DDR3. Unlike prototypes that have been announced year after year (and almost never materialize in the marketplace), the Z2's Power Media Dock is capable of actually using the Radeon with the internal screen instead of forcing you to use an external monitor if you want dedicated graphics performance. The dock also includes additional connectivity along with a DVD+/-RW drive, and more expensive versions can upgrade to a Blu-ray reader or a Blu-ray writer.

    The ONLY comparison you had for these benchmarks is a 17" laptop with one of the most powerful notebook GPUs in the market?
  • Dustin Sklavos - Monday, February 13, 2012 - link

    We just refreshed our benchmarking suite. I explained that. In the review.

    Wait a second... you want us to read, BEFORE flaming??? I'm going back to Yahoo answers!
  • JarredWalton - Monday, February 13, 2012 - link

    Note that we also include 3DMarks for precisely this reason. You can see how graphics performance stands up to previous laptop reviews there, and as we add more laptops to our 2012 test suite, we'll have more comparison points (which will be added to Mobile Bench).

    For this expensive an ultrabook, I would have expected a 16GB max :-P

    I've seen it in a Sony store though...this new 13" 1080p screen is indeed amazing...looking forward to the next generation of tablets w/ 1080p or higher displays :-)

    After reading this review and last night looking at HP EliteBooks and considering their respective price points, who was it again that came up with the whole thang about Apple notebooks being prohibitively expensive!?? I applaud HP for bringing IPS back to notebooks (at 10-bit color no less) but that bag of tricks will set you back way north of $3k unless you'll settle for mediocre specs and a dual-core CPU.

    As for the whole low-wattage deal, Ivy Bridge will do away with those issues in a couple of months and 1080p being considered high screen density? Let's see if those 2880x1440 so-called "Retina" display rumors will come to fruition for MacBook Pro's, because if they do, even a 12" 1200p screen will pale in comparison, and don't go any lower either or you'll bump into a certain "1536p" panel in a 9.7" shell of sorts I keep reading about. Yea, baby. ;-)

    Hi, I'd like to request that future display reviews include comments specific to the display's ability to reproduce smooth gradients (ie, black to white, reds, greens, blues) without any noticeable banding, and the ability to reproduce the minute differences between white/extremely light gray and black/extremely dark gray. The gradient banding, black level, and white saturation test images available at come to mind.

    I know that great LCD monitors are rare in laptops, but to truly distinguish an exceptional laptop display we need to examine more than just resolution, contrast ratio, color gamut, and viewing angles (although those aspects of the display are very important as well!).

    Thanks and keep up the good work!

    This is by far the most powerful ultrabook out now. I have a feeling AMD's ultrathin trinity will give this a good run for its money!

  • JarredWalton - Monday, February 13, 2012 - link

    Except on the CPU aspect, but yes, Trinity should do wonders for IGP performance. 50% faster than the Llano IGP means it should outperform the 6650M and use less power at the same time.

    My friend's Dreamcast broke pretty early on in its lifetime. My PS2 never went bad.

    I believe I have just refuted your entire anecdotal evidence rampage.
