Sony Vaio Z2: Everything is Peripheral
by Dustin Sklavos on February 13, 2012 12:55 AM ESTApplication and Futuremark Performance
Sony's decision to use a full-wattage Intel Core i7 dual-core mobile processor in the VAIO Z2 instead of the 17W CPUs notebooks with these kinds of dimensions usually enjoy means you can expect the Z2 to perform consistently at the top of the heap where application performance is concerned. Add the AMD Radeon HD 6650M in the Power Media Dock to the equation and suddenly you'll also see the Z2 go on a tear in Futuremark's tests. Note that we're focusing on the ultraportable market here, so there are certainly faster laptops around; they're just not available in a sub-14" form factor.
Or at least it should. In PCMark 7 we can see from the Computation score that the Z2 is clearly running the HD 6650M properly (Computation employs Intel's Quick Sync), but the 6650M seems to have a deleterious effect on scores across the board. I have to wonder if PCMark 7 doesn't just outright favor Intel's integrated graphics: notice how every other system with a dedicated GPU clusters at the bottom of most of the charts.
PCMark Vantage proves to be a little more even-handed and scores line up where they ought to be, with the HD 6650M offering an improvement to the Z2's user experience.
Unlike PCMark 7, our application tests reveal no difference in performance between having the Radeon on hand or just using the integrated graphics. These tests are purely CPU bound.
Predictably, the 3DMarks enjoy a substantial boost in performance from switching over to the dedicated AMD Radeon HD 6650M. Unlike the Radeon HD 6470M in Sony's VAIO SB, the 6650M is a definite and notable improvement on Intel's integrated graphics.

You realize this has launched far before any Ultrabooks? It doesn't try to be an Ultrabook, as the article mentioned as well.Also, I'd take a thicker more useful laptop any day of the week over non-upgradeable, small battery Ultrabooks.

I wish sony would ignore the stupid apple air and actually design it without compromises. Make the damn thing thicker (esp at the back as they do/did), quieter, and screen not hitting the table.Anonamouse7 - Monday, February 13, 2012 - link
I absolutely love my Vaio Z (last gen). For me, it's great: enough gaming punch to play some light games (runs TF2/HL2 on low or lower settings, which is fine by me), enough CPU to render videos in decent time periods and good portability. And I adore the screen, even if it's 'just' 900p :3I feel almost compelled to say something though. On the second page of your review you state:
"Unfortunately you're at Sony's mercy for driver updates..."
And therein lies my problem. The last GPU driver update from Sony is dated June 2010! For now, I'll just ignore that even getting to that was an uphill struggle, as my Z is a custom one and the Sony website just kept refusing to recognise it, but since then nVIDIA have released quite a few drivers, and, frankly, it's unacceptable that the 'latest' drivers are over 18 months old.

if its like the 2011 Z, you can just tell the laptop to do more thermal management in the Sony utils. Then it doesnt make much noise at all....As the owner mac and a Z, I have to say I like the Z more (both are nice).

I bought a Z13 December 2010, which I still love in many ways - built-in Blu-Ray writer, discrete graphics, stunning screen, etc. But even when it arrived, the hybrid graphics driver was dated June 2010, i.e. already 6 months out of date, and Sony have not provided an update since. The stock NVIDIA drivers won't work because Sony has built a custom Intel/NVIDIA hybrid package. So customers are at the mercy of Sony for updates.Despite repeated heartfelt appeals to Sony, including the president of the UK operation himself, they have refused to update their graphics driver for this top-of-the-line model, evne during the lifetime of the product. This means that by the time my warranty ended in January 2012, I was using a laptop with a graphics driver 18 months out of date, with no support from Sony whatsoever.
Sony is a company which produces some great hardware, but their abysmal software support does not justify the premium asking price. My lasting impression is one of a company which is all too happy to bank your money quickly then leave you hanging.

...and am extremely happy with it. It's interesting how one's usage model affects the impression of the machine. Mine is mainly coding of embedded applications with cross-compilers, coding of desktop applications, FPGA design and simulation, data-analysis, plus all the normal desktop office-type applications with daily travelling and occasional time-pressured work in difficult conditions thrown in. I rarely have time for gaming these days (boo). My requirements for a laptop are primarly maximum screen resolution and quality, followed by good CPU horsepower for compilation and chip simulation. I've typically had Dells and battery life has typically been <3 hours as a result of my higher priority choices.The Z2 appeared to give me the chance to get what I need in a smaller package, plus long battery life (with the slice). I chose it for size/weight, screen resolution, CPU, battery life in that order. I got the dock purely as a convenient way to connect power, external monitor (27" 2560x1440 over HDMI) and BD/DVD. Mine has 8GB ram and 256GB SSD (twin 128GB).
The Z2 has so far been excellent. The keyboard was odd to start with but I've got used to it now (I remapped right ctrl and application buttons to get convenient home and end keys) and am nearly as fast and accurate with it as a good full-size. I had the slice on from day one so I didn't notice the screen hinge issue mentioned in the review at all. Cold boot to Win7 password prompt is 8 seconds; I have a useable desktop in 12. I had a 256GB Vertex 3 in my previous Dell and this is definitely more responsive to date.
Computational performance has been very good with compilations, chip layouts and simulations taking around half the time of my previous-generation i7 Dell. Fan noise is only noticeable during these high-demand tasks (and yes it does get quite loud then); otherwise the laptop is generally quiet.
The slice has a significant (for me) benefit not noted in the review - it re-routes the vents to the back rather than underneath, allowing safe use of the laptop directly on a fabric surface - like a lap :-)
It is definitely more fragile than a latest generation 14" Dell Latitude (for example - these are excellent machines that we use for many field-personnel) and yes it is indeed expensive but the combination of display, cpu power and form factor is so far more than making up for that, and the 10-12 hours battery life is an extremely welcome bonus.
Just my 2p. Hope it's useful to someone.

+1. It sounds like my usage model is very similar to yours, and I have enjoyed using the Z2 very much.Zoomer - Tuesday, February 14, 2012 - link
Here's Sony's target market! Price doesn't matter that much in the grand scheme of corporate budgets.MarkColby - Wednesday, February 15, 2012 - link
Sorry, wrong. It was a carefully considered personally-funded purchase.dustofnations - Monday, February 13, 2012 - link
Planting Amazon affiliate links one someone else's website is bad enough, but riding on their coattails by trying to make money from the hard work of someone else is truly contemptible.
