Back in May I had the chance to review the Samsung Galaxy S5, and as expected it performed fantastically. However, the Qualcomm Snapdragon 801 equipped model isn't the only S5 version available. The eight-core Exynos-powered model known as the G900H is typically sold in regions with no 4G LTE and comes as a more affordable variant of Samsung's flagship. But how does it compare performance-wise?

The 840 Pro was one of the most successful high-end SSD series over the past few years, and now it's time for an update. Samsung's 850 Pro SSD is powered by the company's cutting-edge in-house 32 layer 3D V-NAND technology, which is said to deliver up to twice the density and write speed of traditional 20nm planar NAND flash.

Intel says overclockers can rejoice over the newest revision of its 4th-gen Core processor, codenamed Devil's Canyon, it promises a few improvements including updated packaging materials, more capacitors for smoother power deliver, and a boost in operating speeds up to 4.4GHz.

Nokia's first Android-powered phone is meant to fit in a new product segment between the low-end Asha feature phones and Lumia smartphones. Despite reading a few pieces on the Nokia X, nothing really prepared me for the first time I used it. After powering it up I was confounded. Surely they didn't release a product that felt so unfinished.

Typically, cases designed with the goal of being silent have been bland looking. But NZXT jazzes things up with the H440 using bright accents -- without looking too flashy -- along a redesigned interior and next-gen FN V2 fans. It also drops the old-fashioned 5.25" drive bays to use the space for other hardware, a move we're interested in seeing other manufacturers make.

Crucial has become a trusted name when it comes to high-performance solid-state drives, but the company's entry-level efforts have been less than laudable to date. They're taking another crack at producing a cost effective SSD with the MX100, and things look more promising this time, thanks to an upgrade to the same Marvell chip used by the high-end M550 series.

Silverstone's latest chassis is unlike anything we have seen. Although it's still a computer case, it isn't designed for gaming or even workstations. The DS380 is aimed directly at users who are building their own NAS, housing up to eight hot-swappable drives and either a DTX or Mini-ITX board.

Last November, Microsoft released the Xbox One. Six months later, the console has gotten a bunch more games and a hefty software upgrade. Microsoft has also decided to sell the Xbox One without the Kinect sensor. Halfway through its first year on planet earth, it's time to revisit our evaluation of the Xbox One.

The Xperia Z2 is the culmination of a series of refinements to Sony's formula, it doesn't stray significantly from the Z1 that came before it, but every upgrade since the original Xperia Z has been of note. We're looking at a top of the line phone with all the latest and greatest specifications, making it a very compelling battle between this and the flagship offerings from Samsung and HTC.

A half-year past launch, the PlayStation 4 still feels like an overachiever. The system runs better and is improving faster than its predecessor. Everything is relative, though. The PS4 is still a year-one console and has familiar year-one issues. It's not yet a must-have but early impressions were correct.

Plextor's new M6 range puts custom firmware, Toshiba NAND flash memory and a Marvell controller in three different packages: a regular 2.5" SATA drive (M6S), an mSATA drive (M6M) and a PCI Express/M.2 version (M6e).

Watch Dogs has been built on the new 'Disrupt' engine, which was mostly constructed from scratch but includes parts of AnvilNext and Dunia, two Ubisoft engines used in the Assassin's Creed series as well as Far Cry 2 and 3. There was a lot of controversy surrounding Watch Dog's graphics approaching its launch but ultimately Ubisoft delivered: the game looks amazing on the PC.

The Logitech G502 Proteus Core is the first mouse to tout a staggering 12,000 DPI. This is complemented by a host of other features that make for the ultimate gaming companion. It's super flexible, working flawlessly on a variety of surfaces, it has five chevron-shaped 3.6g weights, eleven programmable buttons, in-game DPI shifting and dual mouse wheel modes.

Wolfestein's B.J. Blazkowicz was a killing machine whose sole purpose was preventing Nazi Germany from winning World War II at any cost. At the beginning of Wolfenstein: The New Order, he fails. What does a man driven by singular purpose do when that purpose is stripped away?

The Xperia Z2 Tablet is a successor to last year's Xperia Tablet Z, and like what we're seeing in Sony's smartphone range, the device is an incremental update to what came before. The most significant update is the specification bump to Qualcomm's latest Snapdragon 801 SoC along with a sizable weight reduction.

Metadot is arguably responsible for pioneering the commercial mechanical keyboard market much like OCZ did with solid state drives. We've seen a number of revisions and competitors hit the scene since the original Das Keyboard launched in 2005 but their latest offering promises to be an order of magnitude better than previous generations.

Mario Kart was never my game. When it was originally released in 1992, I was already in love with another Nintendo racing game featuring high-tech Mode 7 graphics - F-Zero. Though I dabbled with every Mario Kart release over the last couple of decades they all felt pretty much the same. But this time, within seconds of starting my first race, I could tell this was more than just plain old Mario Kart with fancy HD graphics.

Nearly six years have passed since the Core i7 series debuted. Since then, Intel has been refining it over many iterations through its tick-tock philosophy, which follows every architectural update with a die shrink. Today's release isn't a tick or a tock, it's simply a refresh. But while we don't expect much more than slight speed bumps, the company has also released new 9-series chipsets.

Since the release of the original Galaxy S in 2010, Samsung has been routinely refining their flagship formula through hardware upgrades, software polish and no shortage of gimmicks. We typically see larger displays, more cores, bigger megapixel counts, larger batteries and interesting new additions with every release, and 2014's Galaxy S5 does little to break away from this formula.

Corsair's Carbide Air 540 employs an interesting dual-chamber design and is available in black, white and silver versions. The Obsidian 450D features a more traditional tower case design that looks a lot like a smaller version of the 650D, which is in turn a smaller version of the legendary 800D. Despite these differences in design both are closely priced at $110 and $120.

What happens when Mionix get around to making a mouse that feels as good as it works? You get the Naos 7000, which is a great mouse. On the outside, it looks exactly the same as the company's last few flagship mice. Even feels mostly the same. A few tweaks have been but for the most part it's a case of ain't broke, don't fix.

AMD set its sights on desktops in emerging markets last month, announcing its AM1 platform and the first Kabini-based socket APUs. The platform is more flexible than other budget SoCs, which typically come soldered to motherboards. But in terms of performance how does it compare to the competition?

Back when OCZ released the RevoDrive 3 X2 in 2011, it was the fastest SSD for desktop users we'd seen. Using PCI Express, it eliminated the SATA bottleneck that most SSDs still face today. Three years later, the RevoDrive 350 is being touted as the new ultimate storage solution for intensive workstation applications, with x8 PCIe 2.0 support and read/write speeds of 1.8/1.7GBps.

Unveiled at CES 2014, the latest member to Silverstone's Raven family quickly gained recognition for being the ultimate Steam Machine enclosure. Called the Raven Z RVZ01, this gaming chassis is among the best compact designs we've seen for cramming a fully-fledged enthusiast PC into an impressively small space.

Veering off the beaten path, Acer decided to see what would happen if they took the traditional AIO formula, threw out the Windows operating system and PC hardware, replacing it instead with high-end smartphone guts powered by Android. The TA272 HUL also doubles as a standalone monitor.

The all new HTC One, or HTC One M8, is the evolution of last year's model featuring a larger 5-inch display, a new Duo Camera array that allows after-the-fact refocusing, a faster Snapdragon 801 chipset inside replacing the Snapdragon 600, there's a refined Sense 6.0 interface atop Android 4.4, and much more.

Considering the Radeon R9 290X's record for being pretty hot at its 300w TDP, I had my doubts about AMD placing two Hawaii XT GPUs on a single 500w TDP card. However, with a closed-loop water-cooling system AMD has solved the thermal and acoustic problems that most dual-GPU cards face.

The In Win tou is an $800 enclosure inspired by glass architecture and named after the Chinese word for "transparent". Its tempered glass panels are finished with a special coating that turns the outside into a mirror when your PC is off. However, when illuminated from the inside, the tou's mirror coating becomes transparent.

AMD' Mantle API promises to improve performance in games by allowing them to speak directly to the Graphics Core Next architecture in your GPU or APU and help remove load from your CPU. Now that high profile games Thief and Battlefield 4 support the technology we're ready to take it for a test drive.

We've seen a flurry of 8-inch Windows 8.1 tablets hit the market over the past several months. Next up is the Acer Iconia W4, the follow-up to the company's first Windows 8.1 tablet, featuring an 8.0-inch 1,280 x 800 display and the same quad-core Intel Bay Trail Atom Z3740 that we've seen from the competition.
