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 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? Outside of the specs on paper—which admittedly look quite good—what's the build quality like on the Z2, how does it fare in day to day use, and are there any concerns or benefits that might not immediately stand out? We'll cover that and more as we put this laptop to the test.

With the release of AMD’s Radeon HD 7970 it’s clear that AMD has once again regained the single-GPU performance crown. But while the 7970’s place in the current GPU hierarchy is well established, we’re still trying to better understand the ins and outs of AMD’s new Graphics Core Next Architecture. What does it perform well at and what is it weak at? How might GCN scale with future GPUs? Etc.

Next week we’ll be taking a look at CrossFire performance and the performance of AMD’s first driver update. But in the meantime we wanted to examine a few other facets of the 7970: the impact of PCIe bandwidth on performance, overclocking our reference 7970 (and the performance impact thereof), and what AMD is doing for anti-aliasing with the surprise addition of SSAA for DX10+ along with an interesting technical demo implementing MSAA and complex lighting side-by-side. So let’s get started.

Traditionally the launch of a next-generation high-end video card has been a staggered process. In the name of getting cards out as soon as possible the first cards are almost always reference cards coming preassembled straight from AMD or NVIDIA, which are then touched up in the livery of their partners before being boxed and sold. Only later on – particularly when there’s a solid supply of GPUs – can partners acquire individual parts and put together their custom designs.

But as it’s turning out the Radeon HD 7970 isn’t going to be a traditional launch. In a rare move AMD has loosened the leash on their partners just a bit, and as a result we’re seeing semi-custom cards planned for launch earlier than usual. XFX looks to be the first partner to take advantage of this more liberal policy, as alongside the reference cards being launched today they’re launching their first semi-custom 7970s

At AMD’s Fusion Developer Summit 2011 AMD announced Graphics Core Next, their next-generation GPU architecture. GCN would be AMD’s Fermi moment, where AMD got serious about GPU computing and finally built an architecture that would serve as both a graphics workhorse and a computing workhorse. With the ever increasing costs of high-end GPU development it’s not enough to merely develop graphics GPUs, GPU developers must expand into GPU computing in order to capture the market share they need to live well into the future.

At the same time, by canceling their 32nm process TSMC has directed a lot of hype about future GPU development onto the 28nm process, where the next generation of GPUs would be developed. In an industry accustomed to rapid change and even more rapid improvement never before have GPU developers and their buyers had to wait a full 2 years for a new fabrication process to come online.

All of this has lead to a perfect storm of anticipation for what has become the Radeon HD 7970: not only is it the first video card based on a 28nm GPU, but it’s the first member of the Southern Islands and by extension the first video card to implement GCN. As a result the Radeon HD 7970 has a tough job to fill, as a gaming card it not only needs to deliver the next-generation performance gamers expect, but as the first GCN part it needs to prove that AMD’s GCN architecture is going to make them a competitor in the GPU computing space. Can the 7970 do all of these things and live up to the anticipation? Let’s find out…

Update: This article was originally posted on June 17, 2011. We are pushing it back up to the top as a quick refresher before upcoming articles...

We’ve just returned from sunny Bellevue, Washington, where AMD held their first Fusion Developer Summit (AFDS). As with other technical conferences of this nature such as NVIDIA’s GTC and Intel’s IDF, AFDS is a chance for AMD to reach out to developers to prepare them for future products and to receive feedback in turn. While AMD can make powerful hardware it’s ultimately the software that runs on it that drives sales, so it’s important for them to reach out to developers to ensure that such software is being made.

While AFDS serves many purposes, the final purpose – and what is going to be most interesting to most outside observers – was to prepare developers for what’s coming down the pipe. AMD has big plans for the future and it’s important to get developers involved as soon as is reasonably possible so that they’re ready to use AMD’s future technologies when they launch. Over the next few days we’ll talk about a couple of different things AMD is working on, and today we’ll start with the first and most exciting project: AMD Graphics Core Next, AMD's next generation GPU architecture.

As much as it might pain some of us to hear it, Apple's iMac really did essentially legitimize the all-in-one as an alternative to the typical desktop-and-monitor combination. There have been Windows-based alternatives here and there historically, but it's only been in the past couple of years that the Windows all-in-one market has really started to gain traction. Of course, the fact that system requirements have also reached a point where a large range of CPUs are still sufficiently fast helps.

At present, the iMac's Windows counterparts also offer a functionality that Apple has yet to duplicate: touch interface. HP adds an additional wrinkle with the TouchSmart 610: a hinge that allows you to slide the unit down and use it "kiosk style". That hinge, along with the latest Intel hardware and a surprisingly high quality screen, suggests a machine intended for myriad uses...not just an all-in-one computer, but an all-markets-in-one appliance. Find out how it performs as we put the TouchSmart 610 to the test.

In our first run with the Alienware M18x, we sat down and took a look at the notebook itself along with NVIDIA's current top shelf mobile graphics part, the GeForce GTX 580M. We came away from the experience with mixed impressions of the M18x itself, a notebook that is by all means incredibly powerful but also seems to lose a lot of the balance that made the M17x R3 so desirable. On the other hand, the GeForce GTX 580M wound up being the fastest mobile GPU we'd yet tested, made only more formidable through the SLI configuration the M18x enables.

Today, Alienware has graciously provided us with the second half of the current top shelf performance equation in the form of a near-identically configured M18x, this time with two AMD Radeon HD 6990Ms in CrossFire. We'll also take a look at the Intel Core i7-2920XM's stock performance and compare it against the overclocked settings Alienware allows you to configure it with.

We've had our hands on quite a few gaming notebooks here, but most of the time they're Clevo-based machines. These aren't necessarily bad notebooks; they're fast, typically have good screens, and they get the job done. Yet they also have some persisting drawbacks: build quality isn't often that hot, the battery is a glorified UPS system, and they feature some of the worst keyboards on the market. ASUS, MSI, Toshiba, and HP all offer fairly compelling alternatives, and today Alienware brings us a particularly interesting contender in the form of the M17x R3.

Almost a half-year after the launch of the second-generation Core processors, Intel’s newest CPUs remain dominant in the mid- to high-end desktop computing markets. Since the January release of the initial Sandy Bridge chips, myriad newer, niche-specific CPUs have arrived at retailers. Importantly, the Cougar Point chipset debacle is entirely resolved, with all Sandy Bridge-supporting motherboards available through reputable retailers free of the degrading SATA ports that plagued Sandy Bridge’s first few months.

Like the Sandy Bridge CPUs themselves, the Cougar Point motherboards have diversified into a range of budgets and feature sets. Given the recently announced delay of AMD’s upcoming Bulldozer processors for desktops, Sandy Bridge will remain unchallenged at the high-end of desktop computing until at least September. If you want to build a powerful desktop to use when you’re not lounging by the pool and grilling delicious meats this summer, this guide has you covered with a $500 budget build, a $1,000 midrange system, and a $2,000 high-end gaming-centered system (give or take).
