To say I liked the original Momentus XT would be an understatement. While Seagate had the lofty goal of negating the need for an SSD with its first mass-market hybrid HDD, the reality was the Momentus XT ended up being the best 2.5" hard drive on the market. In many cases, it was fast enough to be better than 3.5" desktop hard drives as well.

Seagate earned this praise by combining a small amount of of SLC NAND (4GB at the time) with a traditional 7200RPM 2.5" hard drive. A separate NAND controller was introduced to handle caching of frequently accessed data to the NAND. By acting solely as a read cache (only read requests to the drive are pulled into the cache), Seagate skirted the complicated issue of effectively building an on-board SSD by only caching reads from the hard drive and not writes to it.

Read on for our review of Seagate's second generation Momentus XT, now with twice as much NAND on-board and a larger 750GB capacity.

It appears that this is the season of inexpensive Android tablets, and with Christmas less than two weeks away, a well-discounted Honeycomb tablet is an interesting gift idea. When Honeycomb debuted, it came hitched to the $799 Motorola Xoom, a device that was a solid first effort but had buggy software and a pricetag that was too high by half. In the following months, Honeycomb became a more mature platform and the price of entry to the Honeycomb club lowered as more devices were released, eventually settling in the $400-500 range. 

Recently during the holiday shopping season, we’ve seen retailers mark some of the lower-end Honeycomb tablets down pretty significantly. We’ve seen tablets like the original ASUS Transformer, the Acer Iconia Tab A500, and the Toshiba Thrive break the $300 mark, with the Thrive at one point going as low as $199. In the $250-300 range, a budget oriented Honeycomb tablet is a pretty tempting buy. Is it worth the 50% savings compared to a higher end tablet like the Samsung Galaxy Tab 10.1 or the new ASUS Transformer Prime? We decided to take a look at Toshiba’s Thrive to figure it out. 

With all of the noise Intel and some of the OEMs are making about ultrabooks, it's easy to forget that as PC users we've already enjoyed thin-and-light and ultraportable notebooks for a while now. Were they sliver-thin? No, but the magical three pound point is something we've always been able to find. Netbooks, for better or worse, only made portability that much more accessible and affordable.

With that in mind, we have on hand Acer's TravelMate 8481T, a notebook that measures under an inch thick (without the battery) and sports an SSD and matte screen. If you were in the market for an ultraportable, this one may be worth your attention. It's not technically an ultrabook, but in some ways that's not necessarily bad.

Recently I reviewed another monitor from BenQ that was designed as an all-in-one model to handle your computer use, as well as TV or video game usage. While the performance of the display was decent, the combination of everything wasn’t an ideal fit.

This new display from BenQ, the VW2420H, has a similar *VA panel and LED backlighting setup as the previous one, but this time it is just a normal monitor. Will it fare better without all the extra features?

In our series of X79 reviews, the next boards to face scrutiny are a pair of ASRock boards – the X79 Extreme4-M, one of the first mATX solutions to X79, and the X79 Extreme4, a full size ATX model.  The main interesting point to consider starts with whether the power consumption and heat generation are applicable to the Sandy Bridge-E platform.  With the socket and quad channel memory taking up serious PCB real estate, it is interesting to see how ASRock have tackled heat dissipation issues.  We also compare the Extreme4-M to the Extreme4, its bigger brother.  Both boards offer amazing value in X79 land, coming in at a recommended retail of $224.99 and $234.99 respectively.  Read on for the full review!

After covering the budget and midrange sectors of the DIY PC market, as well as pre-built desktops and laptops, today we have a guide outlining mainstream high-end builds. Saying the computers outlined in this guide are capable is an understatement—these are seriously powerful (and spendy!) systems. These rigs check out around $2000, at the top of the mainstream market. Each of them will be able to serve their owners well for years to come.

We start with a fancy mini-ITX HTPC that has lots of room for a huge media library and is capable of encoding videos quickly, followed by an impressive gaming box, and finish with a powerful workstation featuring Intel's latest CPU architecture, Sandy Bridge-E.

As promised in our last Opteron "Interlagos" review, we have been taking the time to deepen our understanding of AMD's newest Interlagos server platform and the "Bulldozer" architecture. Server reviewing remains a complex undertaking: some of the benchmarks take hours to set up and run, and power management policies, I/O subsystems and configuration settings can completely alter the outcome of a benchmark. That sounds very obvious right? It is not in practice.

Let me give you an example how subtle server benchmarking can be. One of the benchmarks missing in the original review was the MS SQL server benchmark, and for a reason. We did some extensive scaling benchmarks and our gut feeling told us that some of the results were a bit off the mark. So we kept the benchmark out of the original review until we pinpointed the problem.

Just a few days ago, we found out that a tiny bit of time-outs (1%, caused mostly by a data provider time out setting) can boost the results by about 20% erroneously as the actual workload is decreased. So our MS SQL server benchmark was not as accurate as we thought it was. Luckily we have solved all problems, and the benchmark is now more accurate than ever. You can expect to see the MS SQL server benchmarks on different server platforms and an in depth analysis in a forthcoming article.

While solving the MS SQL Server benchmark issues required a lot of testing, analysis and debate with Dieter, the lead developer of our stress testing tool vApus, we missed a more obvious tweak that could have improved our blender benchmarking. Luckily, we still have a community that is willing to give us valuable feedback. Greg Wereszko point out that our Blender benchmark cuts the render job up into only 64 tiles (X=8, Y=8). The result is that near the end of the test several cores are inactive, especially on the Interlagos Opteron (32 cores/threads).

So we increased the number of tiles beyond 8x8, to check if this improves performance on our 32 and 24 thread machines, and it did. (Quick note: the Blender benchmark on Windows is one of the worst benchmarks for the Opteron Interlagos, so see this as "worst case" performance point.)

Instead of trailing behind the Opteron 6174, the Opteron "Interlagos" 6276 manages to perform a tiny bit better than its older sibling when we use 256 (16x16) tiles. The Opteron 6276 improves performance by 24%, the Xeon X5650 and Opteron 6174 by 19%. 

Using more tiles, all CPUs are able to show their top performance. It also shows the rather "fragile performance profile" of the new Opteron. Many users are going to use standard settings and will never bother with this kind of tuning. As a result they are not going to use the full potential of the new Opteron. The Xeon's higher single-threaded performance makes it less vulnerable to less optimal software settings.

At the other side of the coin, once well tuned the Opteron 62xx offers an interesting performance per dollar ratio and this "fragile performance profile" may become very robust in FP intensive applications once the use of AVX gets widespread. We are taking quite a bit of time to make sure that the next server article can give more detailed information, but rest assured that we did not give up: we will update our server benchmarking...when it is finished.

If you're willing to shell out the money for them, there are a lot of interesting alternative enclosure designs on the market. Companies like SilverStone, Thermaltake, and Lian Li are happy to sell you more experimental and exotic cases once you get past $150 or so, but what if you want something a little spicier without breaking the bank? At $99 Lian Li has you covered with the new PC-A05FN. There are a lot of good (or at least interesting) ideas at work in the PC-A05FN, but how well do they pan out?

AMD briefed us last week on several new and upcoming technologies and announcements. We’ve covered the AMD Memory announcement, and next up on the list is AMD’s Radeon Mobility HD 7000M. While we were getting this article ready, we also had NVIDIA launch their updated GeForce 600M parts without so much as a brief heads-up email. There’s reasons for that, which we’ll cover in this article, but we’ll start with a look at AMD’s new mobile parts before getting into the NVIDIA update.

So, what will 7000M bring to the table? Right now, not a whole lot that we haven’t already seen before. Traditionally AMD and NVIDIA have launched their new series of graphics products at the high-end and worked their way down. The high-end GPUs are the flag bearers of a generation, with new architectures being built on these large chips first before lesser products are derived from them. If we group the 7000M with the 7000 series in general (or the 600M with the 600 series), both companies are moving to their “next generation” parts on mobile first. Are we looking at a fundamental shift in the way things are done? Not really; read on to find out why.

The latest edition of our Holiday 2011 guides focuses on midrange desktops. If you enjoy the prospect of building your own PC or you just prefer the ability to customize every component, we'll have recommendations. We'll outline three different systems at $800, $1000, and $1200, with processors from AMD and Intel.

The first system we've put together is an AMD Llano APU-based PC designed to deliver acceptable gaming performance at medium resolutions as well as great "daily driver" general computing performance. Next up, we cover our latest iteration of a now "classic" i5-2500K build that offers better gaming and computing capabilities for a few hundred dollars more than the AMD build. Finally, we have an i7-2600K rig that focuses on raw computational power and eschews graphics for the time being (though you can easily add your own). So whether you're upgrading or building new, we have suggestions. Read on for more details.

If you browse custom builds across different boutiques, you'll find NZXT's name comes up an awful lot. One of their enclosures, in particular, tends to see a lot of action: the Phantom. Its unusual angular design for some people is the right mix of style and gaudy, resembling the kind of case an Imperial Stormtrooper might choose if they were planning on learning how to at least hit the broad side of a barn in their off-duty hours. Today we take the wraps off of the Phantom's new fun size version, the Phantom 410, offering all the style without the massive footprint.

We say it every year, but the trends continue so we’ll keep repeating it: laptops and mobile devices are becoming increasingly popular, often at the cost of desktop sales. This year we saw a lot of people looking at smartphones and tablets along with laptops, and sales of those devices have skyrocketed. Still, if you need to do some serious work—writing a large document or email, working on a spreadsheet or presentation, etc.—you still need a real computer while you travel. Whether you want something for work, school, or play, we’ve got recommendations in our annual…

So pull up a chair, wrap up in a nice blanket, and get yourself a steaming cup of hot chocolate while we cover the laptop market from top to bottom. Netbooks, Chromebooks, ultrabooks, laptops and notebooks—we’ve got it all right here. Even better, you can do some of your Christmas shopping without even leaving the comforts of your own home. What better way to enjoy the season than by staying indoors?

Going from making good motherboards to going head to head with Samsung for Google's affection is a pretty big step for ASUS, but it's one that the company has taken and done very well with. None of its peers have made the same transition, especially not while continuing to thrive in their existing businesses. I don't think anyone can say that ASUS' motherboards have suffered over the past several years as the company has transitioned, much like Apple, into the world of being a mobile computer manufacturer.

ASUS' first Android tablet was a knock out of the park. The original Eee Pad Transformer gave us a glimpse of the future with its keyboard dock while delivering a good Honeycomb experience for $100 less than the competition. As many sacrifices as ASUS had to make to reach its price point, the original Eee Pad remains one of the best Honeycomb tablets on the market. But the show must go on and simply being the cheapest on the block doesn't work anymore, particularly with companies like Amazon redefining what cheap means. It was time for a new flagship and today we have that tablet:

Priced at $499 the Eee Pad Transformer Prime will be available in North America during the week of 12/19. Read on for our full review!

While we at AnandTech recognize that a good portion of our readership prefers to roll their own as far as desktops go, not everyone is that way. Sometimes there are also situations where we'd be better off just recommending a pre-built desktop to family than damning ourselves to being tech support at all hours for the next few years. With that in mind, we bring you our...

If you want to kick back for a change, send something to family or a friend, or whatever your reason for going with a pre-built system, we have a recommendation for you this holiday season.

Earlier this month we reviewed Intel's new ultra high end CPU: Sandy Bridge E. The 2.7 billion transistor chip is a serious workhorse, overkill for most enthusiasts but a dream come true if you do a lot of video encoding, offline 3D rendering or any other heavily threaded task. The platform is expensive but Gigabyte gave us a pair of its X79-UD5 motherboards to give away to any of our readers that might be interested in going down the LGA-2011 path.

A little more than a year ago NVIDIA introduced the GF110 GPU, the power-optimized version of their Fermi patriarch, GF100. The first product was their flagship GTX 580, followed by the eventual GTX 570. Traditionally NVIDIA would follow this up with a 3^rd product. The GTX 200 series had 285/275/260, and the GTX 400 series had GTX 480/470/465. However in the past year we have never seen the 3^rd tier GF110 card… until now.

Today NVIDIA will be launching the GeForce GTX 560 Ti With 448 Cores (and yes, that’s the complete name), a limited edition product that will serve as the 3^rd tier product, at least for a time. And while NVIDIA won't win any fans with the name, the performance is another matter entirely. If you've ever wanted a GTX 570 but didn't want to pay the $300+ price tag, as we'll see NVIDIA has made a very convincing argument that this is the card for you.

I'll be honest here (I always am?): I don't understand the iPad comparison. The Kindle Fire and iPad 2 couldn't be more different. They are vastly different sizes, shapes and prices. They even serve slightly different functions. The search for an iPad killer reminds me of the search for a Voodoo killer back during the heyday of 3dfx in the late 1990s.

The Kindle Fire serves entirely different purposes than to take marketshare away from Apple.

Why would Amazon enter the IPS LCD equipped multitouch tablet business to begin with? For users who are content reading ebooks on an e-ink screen, the vanilla Kindles are as good as they get. The problem is for users looking to consolidate devices, they may find themselves carrying a Kindle and a tablet of some sort (likely an iPad) and will ultimately ditch the Kindle in favor of the iPad. Should these users replace their Kindles with iPads, there's the argument that Apple could tempt them away from Amazon's Kindle store altogether. If they want a more affordable tablet however they are likely going to be forced into a solution that's probably not very good. Neither possibility is something Amazon likes, so the obvious answer is to offer a Kindle that delivers enough of the tablet experience that will satisfy those users looking for more than an e-ink Kindle could provide.

The Fire is that Kindle. Read on for our full review!

Amazon announced three new Kindles back in September: the fourth generation Kindle, the Kindle Touch (and Kindle Touch 3G, both of which are identical aside from the 3G antenna), and the Kindle Fire. The Kindle 4 was available on the same day, and we've already taken a good look at it. Our Kindle Fire review is forthcoming. That leaves the Kindle Touch, which we're going to talk about today.

The Kindle Touch is Amazon's first touchscreen e-reader - past Kindles have used nothing but buttons for navigation, even as competing products like Barnes & Noble's Nook Simple Touch began to incorporate touchscreens. At $99 and $149 for the wi-fi and 3G versions ($139 and $189 for the ad-free Kindles), the Kindle Touch is priced competitively, but how does the touchscreen actually impact your reading experience? Read on for our thoughts.
