Introduction and First Impressions
The Lian Li PC-Q33 is a mini-ITX enclosure with a cube-like appearance and a hinged construction that makes it easy to access the components within.
When a builder is contemplating a mini-ITX system the primary driver is going to be the size. It’s incredible that we've reached the point where we can have a powerful single-GPU system with minimal (if any) tradeoffs from the tiny mITX form-factor, but the components need to be housed in an appropriately small enclosure or the entire purpose is defeated. However working within small enclosures is often more difficult, unless the enclosure has been specifically designed to account for this. Certainly no slouch in the design department, Lian Li is no stranger to small, lightweight mini-ITX designs like this. The NCASE M1 (a personal favorite) was manufactured by the company after all, and in some ways the PC-Q33 is reminiscent of that design - in build quality and materials if nothing else. The Q33 features aluminum construction and is very light, and while compact the design of the enclosure allows for effortless component installation. The secret? A hinged design that allows the front of the enclosure to swing down providing full access to the interior.
This approach to accessibility with a small enclosure is a welcome one, and especially so considering the price of the PC-Q33, which retails for $95 on Newegg and can be found for around $105 on Amazon as well. This is still a high cost for many considering a small build and enters the premium price range for an enclosure, but remember the Q33 features an aluminum construction which typically carries a considerably higher cost than steel and plastic. Of course if the case is frustrating to use or has poor thermals than the materials used are meaningless, so in this review we’ll look at the build process and thermal results with the Q33 to see if it’s a good value. My initial impression is that the price is actually low, but that’s coming from someone who looks at a lot of cases and develops a familiarity with the average retail prices in each category.

The X99-A is the base level board in ASUS' Intel X99 line of motherboard offering. Don't let the term "base level offering" throw you off though, ASUS put their best foot forward in designing this beauty. The board features full support for all Intel LGA2011-3 based processors paired with DDR4 memory operating in up to a quad channel configuration. Priced at a competitive price point of $274.99, the X99-A gives the more feature-packed (and vastly more expensive) boards a run for their money.

Just because the X99-A motherboard is designed to be the "entry-level" model of ASUS' X99 product line does not mean that they skimped on its design or features. The X99-A features the enhanced OC Socket and an 8+4 phase digital power system similar to that featured on its more costly siblings, centered around the Extreme Engine Digi+ IV solution. Extreme Engine Digi+ IV combines ASUS' custom designed Digi+ EPU chipset, IR (International Rectifier) sourced MOSFETs, high-quality chokes, and 10k Black Metallic capacitors for unrivaled power delivery capabilities. The board is further augmented by the integration of ASUS' Crystal Sound 2 audio subsystem for superior audio reproduction.
Introduction and Specifications
Had you asked me just a few years ago if 6-inch phones would not only be a viable option, but a dominant force in the mobile computing market, I would have likely rolled my eyes. At that time phones were small, tablets were big, and phablets were laughed at. Today, no one is laughing at the Galaxy Note 4, the latest iteration in Samsung’s created space of larger-than-you-probably-thought-you-wanted smartphones. Nearly all consumers are amazed by the size of the screen and the real estate this class of phone provides but some are instantly off put by the way the phone feels in the hand – it can come off as foreign, cumbersome, and unusable.
In my time with the new Galaxy Note 4 – my first extended-use experience with a phone of this magnitude – I have come to see the many positive traits that a larger phone can offer. There are some trade-offs of course, including the pocket/purse viability debate. One thing beyond question is that a large phone means a big screen. One that can display a large amount of data whether that be on a website or in a note-taking application. The extra screen real estate can instantly improve your productivity. To that end Samsung also provides a multi-tasking framework that lets you run multiple programs in a side-by-side view, similar to what the original version of Windows 8 did. It might seem unnecessary for an Android device, but as soon as you find the situation where you need it going back to a device without it can feel archaic.
A larger phone also means that there is more room for faster hardware, a larger camera sensor, and a bigger battery. Samsung even includes an active stylus called the S-Pen in the body of the device – something that few other modern tablets/phablets/phones feature.
Introduction and Design
Although the target market and design emphasis may be different, there is one thing consumer and business-grade laptops have in common: a drift away from processing power and toward portability and efficiency. At the risk of repeating our introduction for the massive MSI GT72 gaming notebook we reviewed last month, it seems that battery life, temperature, and power consumption get all the attention these days. And arguably, it makes sense for most people: it’s true that CPU performance gains have in years past greatly outstripped the improvements in battery life, and that likewise performance gains could be realized far more easily by upgrading storage device speed (such as by replacing conventional hard drives with solid-state drives) than by continuing to focus on raw CPU power and clock rates. As a result, we’ve seen many mobile CPU speeds plateauing or even dropping in exchange for a reduction in power consumption, while simultaneously cases have slimmed and battery life has jumped appreciably across the board.
But what if you’re one of the minority who actually appreciates and needs raw computing power? Fortunately, Lenovo’s ThinkPad W series still has you covered. This $1,500 workstation is the business equivalent of the consumer-grade gaming notebook. It’s one of the few designs where portability takes a backseat to raw power and ridiculous spec. Users shopping for a ThinkPad workstation aren’t looking to go unplugged all day long on an airplane tray table. They’re looking for power, reliability, and premium design, with function over form as a rule. And that’s precisely what they’ll get.
Beyond the fairly-typical (and very powerful) Intel Core i7-4800MQ CPU—often found in gaming PCs and workstations—and just 8 GB of DDR3-1600 MHz RAM (single-channel) is a 256 GB SSD and a unique feature to go along with the WQHD+ display panel: built-in X-Rite Pantone color sensor which can be used to calibrate the panel simply by closing the lid when prompted. How well this functions is another topic entirely, but at the very least, it’s a novel idea.
Introduction and Features
Earlier this year we took a look at SilverStone’s ST1500-GS power supply unit, which currently has the highest rated output in the Strider Gold S Series. Today we are looking at SilverStone’s second generation Strider Gold ST75F-GS V2.0, which is a 750 watt power supply that comes housed in a short chassis; only 140mm (5.5”) deep for easy integration. It’s nice to get a different model from the same series in for review to see how the series overall performs. SilverStone claims the Strider Gold S Series are the world’s smallest, full-modular ATX power supplies.

Finally, a SHIELD Console
NVIDIA is filling out the family of the SHIELD brand today with the announcement of SHIELD, a set-top box powered by the Tegra X1 processor. SHIELD will run Android TV and act as a game playing, multimedia watching, GRID streaming device. Selling for $199 and available in May of this year, there is a lot to discuss.
Odd naming scheme aside, the SHIELD looks to be an impressive little device, sitting on your home theater or desk and bringing a ton of connectivity and performance to your TV. Running Android TV means the SHIELD will have access to the entire library of Google Play media including music, movies and apps. SHIELD supports 4K video playback at 60 Hz thanks to an HDMI 2.0 connection and fully supports H.265/HEVC decode thanks to Tegra X1 processor.
Here is a full breakdown of the device's specifications.
|NVIDIA SHIELD Specifications|
|Processor||NVIDIA® Tegra® X1 processor with 256-core Maxwell™ GPU with 3GB RAM|
|Video Features||4K Ultra-HD Ready with 4K playback and capture up to 60 fps (VP9, H265, H264)|

|Options||SHIELD controller, SHIELD remove, SHIELD stand|
Obviously the most important feature is the Tegra X1 SoC, built on an 8-core 64-bit ARM processor and a 256 CUDA Core Maxwell architecture GPU. This gives the SHIELD set-top more performance than basically any other mobile part on the market, and demos showing Doom 3 and Crysis 3 running natively on the hardware drive the point home. With integrated HEVC decode support the console is the first Android TV device to offer the support for 4K video content at 60 FPS.
Even though storage is only coming in at 16GB, the inclusion of an MicroSD card slot enabled expansion to as much as 128GB more for content and local games.
The first choice for networking will be the Gigabit Ethernet port, but the 2x2 dual-band 802.11ac wireless controller means that even those of us that don't have hardwired Internet going to our TV will be able to utilize all the performance and features of SHIELD.
As GDC progresses here in San Francisco, AMD took the wraps off of a new SDK for game developers to use to improve experiences with virtual reality (VR) headsets. Called LiquidVR, the goal is provide a smooth and stutter free VR experience that is universal across all headset hardware and to keep the wearer, be it a gamer or professional user, immersed.
AMD's CTO of Graphics, Raja Koduri spoke with us about the three primary tenets of the LiquidVR initiative. The 'three Cs' as it is being called are Comfort, Compatibility and Compelling Content. Ignoring the fact that we have four C's in that phrase, the premise is straight forward. Comfortable use of VR means there is little to no issues with neusea and that can be fixed with ultra-low latency between motion (of your head) and photons (hitting your eyes). For compatibility, AMD would like to assure that all VR headsets are treated equally and all provide the best experience. Oculus, HTC and others should operate in a simple, plug-and-play style. Finally, the content story is easy to grasp with a focus on solid games and software to utilize VR but AMD also wants to ensure that the rendering is scalable across different hardware and multiple GPUs.
To address these tenets AMD has built four technologies into LiquidVR: late data latching, asynchronous shaders, affinity multi-GPU, and direct-to-display.
The idea behind late data latching is to get the absolute most recent raw data from the VR engine to the users eyes. This means that rather than asking for the head position of a gamer at the beginning of a render job, LiquidVR will allow the game to ask for it at the end of the rendering pipeline, which might seem counter-intuitive. Late latch means the users head movement is tracked until the end of the frame render rather until just the beginning, saving potentially 5-10ms of delay.
Who Should Care? Thankfully, Many People
The Khronos Group has made three announcements today: Vulkan (their competitor to DirectX 12), OpenCL 2.1, and SPIR-V. Because there is actually significant overlap, we will discuss them in a single post rather than splitting them up. Each has a role in the overall goal to access and utilize graphics and compute devices.
Before we get into what everything is and does, let's give you a little tease to keep you reading. First, Khronos designs their technologies to be self-reliant. As such, while there will be some minimum hardware requirements, the OS pretty much just needs to have a driver model. Vulkan will not be limited to Windows 10 and similar operating systems. If a graphics vendor wants to go through the trouble, which is a gigantic if, Vulkan can be shimmed into Windows 8.x, Windows 7, possibly Windows Vista despite its quirks, and maybe even Windows XP. The words “and beyond” came up after Windows XP, but don't hold your breath for Windows ME or anything. Again, the further back in Windows versions you get, the larger the “if” becomes but at least the API will not have any “artificial limitations”.
Outside of Windows, the Khronos Group is the dominant API curator. Expect Vulkan on Linux, Mac, mobile operating systems, embedded operating systems, and probably a few toasters somewhere.
On that topic: there will not be a “Vulkan ES”. Vulkan is Vulkan, and it will run on desktop, mobile, VR, consoles that are open enough, and even cars and robotics. From a hardware side, the API requires a minimum of OpenGL ES 3.1 support. This is fairly high-end for mobile GPUs, but it is the first mobile spec to require compute shaders, which are an essential component of Vulkan. The presenter did not state a minimum hardware requirement for desktop GPUs, but he treated it like a non-issue. Graphics vendors will need to be the ones making the announcements in the end, though.
Introduction and First Impressions
The RV05 is the current iteration of SilverStone's Raven enclosure series, and a reinvention of their ATX enthusiast design with a revised layout that eliminates 5.25" drive bays for a smaller footprint.
Return to Form
The fifth edition of SilverStone's Raven is a return to form of sorts, as it owes more to the design of the original RV01 than the next three to follow. The exterior again has an aggressive, angular look with the entire enclosure sitting up slightly at the rear and tilted forward. Though the overall effect is likely less visually exciting than the original, depending on taste, in its simplicity the design feels more refined and modern than the RV01. Some of the sharpest angles have been eliminated or softened, though the squat stance coupled with its smaller size gives the RV05 an energetic appearance - as if it's ready to strike. (OK, I know it's just a computer case, but still...)
The Raven series is important to the case market as a pioneer of the 90º motherboard layout for ATX systems, expanding on the design originally developed by Intel for the short-lived BTX form-factor. In the layout implemented in the Raven series the motherboard is installed with the back IO panel facing up, which requires the graphics card to be installed vertically. This vertical orientation assists with heat removal by exploiting the tendency of warm air to rise, and when implemented in an enclosure like the RV05 it can create an excellent thermal environment for your components. The RV05 features large fans at the bottom of the case that push air upward and across the components on the motherboard, forcing warm air to exit through a well-ventilated top panel.
And the RV05 isn't just a working example of an interesting thermal profile, it's actually a really cool-looking enclosure with some premium features and suprisingly low price for a product like this at $129 on Amazon as this was written. In our review of the RV05 we'll be taking a close look at the case and build process, and of course we'll test the thermal performance with some CPU and GPU workloads to find out just how well this design performs.
SoFIA, Cherry Trail Make Debuts
Mobile World Congress is traditionally dominated by Samsung, Qualcomm, HTC, and others yet Intel continues to make in-roads into the mobile market. Though the company has admittedly lost a lot of money during this growing process, Intel pushes forward with today's announcement of a trio of new processor lines that keep the Atom brand. The Atom x3, the Atom x5, and the Atom x7 will be the company's answer in 2015 for a wide range of products, starting at the sub-$75 phone market and stretching up to ~$400 tablets and all-in-ones.
There are some significant differences in these Atom processors, more than the naming scheme might indicate.
Intel Atom x3 SoFIA Processor
For years now we have questioned Intel's capability to develop a processor that could fit inside the thermal envelope that is required for a smartphone while also offering performance comparable to Qualcomm, MediaTek, and others. It seemed that the x86 architecture was a weight around Intel's ankles rather than a float lifting it up. Intel's answer was the development of SoFIA, (S)mart (o)r (F)eature phone with (I)ntel (A)rchitecture. The project started about 2 years ago leading to product announcements finally reaching us today. SoFIA parts are "designed for budget smartphones; SoFIA is set to give Qualcomm and MediaTek a run for their money in this rapidly growing part of the market."
The SoFIA processors are based on the same Silvermont architecture as the current generation of Atom processors, but they are more tuned for power efficiency. Originally planned to be a dual-core only option, Intel has actually built both dual-core and quad-core variants that will pair with varying modem options to create a combination that best fit target price points and markets. Intel has partnered with RockChip for these designs, even though the architecture is completely IA/x86 based. Production will be done on a 28nm process technology at an unnamed vendor, though you can expect that to mean TSMC. This allows RockChip access to the designs, to help accelerate development, and to release them into the key markets that Intel is targeting.
Introduction and Technical Specifications
Courtesy of Cooler Master
Cooler Master is known in the enthusiast community for their innovative designs with product offerings ranging from cases to desktop and laptop cooling implements. Cooler Master also offers their own line of all-in-one (AIO) CPU liquid cooling solutions for better system performance without the noise of a typical air cooler. With their Nepton 240M cooler, they enhanced the existing design of their previous AIO products, optimizing its performance with an enhanced pump and radiator design. We measured the unit's performance against that of other high-performance liquid and air coolers to best illustrate its abilities. The Nepton 240M's premium performance comes with a premium price, at a $139.99 MSRP.

The Nepton 240M AIO liquid cooler features a 240mm aluminum-finned radiator tied to a base unit consisting of a 120 liter per minute pump and a micro-finned copper base plate. Unlike the Glacer model, the Nepton 240M does not feature the ability to drain and refill the unit. Cooler Master designed the Nepton 240M with a 27mm deep, 2x120mm copper radiator with brass internal channels, bundled with two of its 120mm Silencio model fans. The Silencio fans are optimized for low noise and high pressure, perfect for use with a liquid cooling radiator. The radiator and unit base are connected by ribbed FEP (Fluorinated Ethylene Propylene) tubing, allowing for high flexibility without the worry of tube kinking.
Quiet, Efficient Gaming
The last few weeks have been dominated by talk about the memory controller of the Maxwell based GTX 970. There are some very strong opinions about that particular issue, and certainly NVIDIA was remiss on actually informing consumers about how it handles the memory functionality of that particular product. While that debate rages, we have somewhat lost track of other products in the Maxwell range. The GTX 960 was released during this particular firestorm and, while it also shared the outstanding power/performance qualities of the Maxwell architecture, it is considered a little overpriced when compared to other cards in its price class in terms of performance.
It is easy to forget that the original Maxwell based product to hit shelves was the GTX 750 series of cards. They were released a year ago to some very interesting reviews. The board is one of the first mainstream cards in recent memory to have a power draw that is under 75 watts, but can still play games with good quality settings at 1080P resolutions. Ryan covered this very well and it turned out to be a perfect gaming card for many pre-built systems that do not have extra power connectors (or a power supply that can support 125+ watt graphics cards). These are relatively inexpensive cards and very easy to install, producing a big jump in performance as compared to the integrated graphics components of modern CPUs and APUs.
The GTX 750 and GTX 750 Ti have proven to be popular cards due to their overall price, performance, and extremely low power consumption. They also tend to produce a relatively low amount of heat, due to solid cooling combined with that low power consumption. The Maxwell architecture has also introduced some new features, but the major changes are to the overall design of the architecture as compared to Kepler. Instead of 192 cores per SMK, there are now 128 cores per SMM. NVIDIA has done a lot of work to improve performance per core as well as lower power in a fairly dramatic way. An interesting side effect is that the CPU hit with Maxwell is a couple of percentage points higher than Kepler. NVIDIA does lean a bit more on the CPU to improve overall GPU power, but most of this performance hit is covered up by some really good realtime compiler work in the driver.
Asus has taken the GTX 750 Ti and applied their STRIX design and branding to it. While there are certainly faster GPUs on the market, there are none that exhibit the power characteristics of the GTX 750 Ti. The combination of this GPU and the STRIX design should result in an extremely efficient, cool, and silent card.
Project Lead: Joris-Jan van ‘t Land
Thanks to Ian Comings, guest writer from the PC Perspective Forums who conducted the interview of Bohemia Interactive's Joris-Jan van ‘t Land. If you are interested in learning more about ArmA 3 and hanging out with some PC gamers to play it, check out the PC Perspective Gaming Forum!
I recently got the chance to send some questions to Bohemia Interactive, a computer game development company based out of Prague, Czech Republic, and a member of IDEA Games. Bohemia Interactive was founded in 1999 by CEO Marek Španěl, and it is best known for PC gaming gems like Operation Flashpoint: Cold War Crisis, The ArmA series, Take On Helicopters, and DayZ. The questions are answered by ArmA 3's Project Lead: Joris-Jan van ‘t Land.
PC Perspective: How long have you been at Bohemia Interactive?
VAN ‘T LAND: All in all, about 14 years now.
PC Perspective: What inspired you to become a Project Lead at Bohemia Interactive?
VAN ‘T LAND: During high school, it was pretty clear to me that I wanted to work in game development, and just before graduation, a friend and I saw a first preview for Operation Flashpoint: Cold War Crisis in a magazine. It immediately looked amazing to us; we were drawn to the freedom and diversity it promised and the military theme. After helping run a fan website (Operation Flashpoint Network) for a while, I started to assist with part-time external design work on the game (scripting and scenario editing). From that point, I basically grew naturally into this role at Bohemia Interactive.
PC Perspective: What part of working at Bohemia Interactive do you find most satisfying? What do you find most challenging?
VAN ‘T LAND: The amount of freedom and autonomy is very satisfying. If you can demonstrate skills in some area, you're welcome to come up with random ideas and roll with them. Some of those ideas can result in official releases, such as Arma 3 Zeus. Another rewarding aspect is the near real-time connection to those people who are playing the game. Our daily Dev-Branch release means the work I do on Monday is live on Tuesday. Our own ambitions, on the other hand, can sometimes result in some challenges. We want to do a lot and incorporate every aspect of combat in Arma, but we're still a relatively small team. This can mean we bite off more than we can deliver at an acceptable level of quality.
PC Perspective: What are some of the problems that have plagued your team, and how have they been overcome?
VAN ‘T LAND: One key problem for us was that we had no real experience with developing a game in more than one physical location. For Arma 3, our team was split over two main offices, which caused quite a few headaches in terms of communication and data synchronization. We've since had more key team members travel between the offices more frequently and improved our various virtual communication methods. A lot of work has been done to try to ensure that both offices have the latest version of the game at any given time. That is not always easy when your bandwidth is limited and games are getting bigger and bigger.
AMD Details Carrizo Further
Some months back AMD introduced us to their “Carrizo” product. Details were slim, but we learned that this would be another 28 nm part that has improved power efficiency over its predecessor. It would be based on the new “Excavator” core that will be the final implementation of the Bulldozer architecture. The graphics will be based on the latest iteration of the GCN architecture as well. Carrizo would be a true SOC in that it integrates the southbridge controller. The final piece of information that we received was that it would be interchangeable with the Carrizo-L SOC, which is a extremely low power APU based on the Puma+ cores.
A few months later we were invited by AMD to their CES meeting rooms to see early Carrizo samples in action. These products were running a variety of applications very smoothly, but we were not informed of speeds and actual power draw. All that we knew is that Carrizo was working and able to run pretty significant workloads like high quality 4K video playback. Details were yet again very scarce other than the expected timeline of release, the TDP ratings of these future parts, and how it was going to be a significant jump in energy efficiency over the previous Kaveri based APUs.
AMD is presenting more information on Carrizo at the ISSCC 2015 conference. This information dives a little deeper into how AMD has made the APU smaller, more power efficient, and faster overall than the previous 15 watt to 35 watt APUs based on Kaveri. AMD claims that they have a product that will increase power efficiency in a way not ever seen before for the company. This is particularly important considering that Carrizo is still a 28 nm product.
Intel Pushes Broadwell to the Next Unit of Computing
Intel continues to invest a significant amount of money into this small form factor product dubbed the Next Unit of Computing, or NUC. When it was initially released in December of 2012, the NUC was built as an evolutionary step of the desktop PC, part of a move for Intel to find new and unique form factors that its processors can exist in. With a 4" x 4" motherboard design the NUC is certainly a differentiating design and several of Intel's partners have adopted it for products of their: Gigabyte's BRIX line being the most relevant.
But Intel's development team continues to push the NUC platform forward and today we are evaluating the most recent iteration. The Intel NUC5i5RYK is based on the latest 14nm Broadwell processor and offers improved CPU performance, a higher speed GPU and lower power consumption. All of this is packed into a smaller package than any previous NUC on the market and the result is both impressive and totally expected.
A Walk Around the NUC
To most poeple the latest Intel NUC will look very similar to the previous models based on Ivy Bridge and Haswell. You'd be right of course - the fundamental design is unchanged. But Intel continues to push forward in small ways, nipping and tucking away. But the NUC is still just a box. An incredibly small one with a lot of hardware crammed into it, but a box none the less.
While I can appreciate the details including the black and silver colors and rounded edges, I think that Intel needs to find a way to add some more excitement into the NUC product line going forward. Admittedly, it is hard to inovate in that directions with a focus on size and compression.
Just over a week or so ago Allyn spent some time with the MSI X99A Gaming 9 ACK motherboard, a fact that might seem a little odd to our frequent readers. Why would our storage editor be focusing on a motherboard? USB 3.1 of course! When we visited MSI at CES in January they were the first company to show working USB 3.1 hardware and performance numbers that we were able duplicate in our testing when MSI sent us similar hardware.
But ASUS is in this game as well, preparing its product lines with USB 3.1 support courtesy of the same ASMedia controller we looked at before. ASUS has a new revision of several motherboards planned with integrated on-board USB 3.1 but is also going to be releasing an add-in card with USB 3.1 support for existing systems.
Today we are going to test that add-in card to measure ASUS' implementation of USB 3.1 and see how it stacks up to what MSI had to offer and what improvements and changes you can expect from USB 3.0.
USB 3.1 Technology Background
Despite the simple point denomination change in USB 3.1, also known as SuperSpeed+, the technological and speed differences in the newest revision of USB are substantial. Allyn did a good job of summarizing the changes that include a 10 Gbps link interface and a dramatic drop in encoding overhead that enables peak theoretical performance improvements of 2.44x compared to USB 3.0.
USB 3.1 is rated at 10 Gbps, twice that of USB 3.0. The little-reported-on nugget of info from the USB 3.1 specification relates to how they classify the raw vs. expected speeds. Taking USB 3.0 as an example, Superspeed can handle a raw 5Gbps data rate, but after subtracting out the overhead (packet framing, flow control, etc), you are left with ~450MB/s of real throughput. Superspeed+ upgrades the bit encoding type from 8b/10b (80% efficient) to 128b/132b (97% efficient) *in addition to* the doubling of raw data rate. This means that even after accounting for overhead, Superspeed+’s best case throughput should work out to ~1.1GB/s. That’s not a 2x speed improvement – it is actually 2.44x of USB 3.0 speed. Superspeed+ alright!
The ASUS STRIX TACTIC PRO is a premium mechanical gaming keyboard featuring Cherry MX Brown switches and some serious style.
Keyboards are a very personal thing, and as this is one of the three primary interfaces with the system itself (along with the mouse and display), feel will help decide the experience. Without a doubt mechanical keyboard have become very popular with enthusiasts, but as more manufacturers have started offering them - and the market has begun to saturate - it becomes much more difficult to pick a starting point if you're new to the game. To further complicate a buying decision there are different types of key switches used in these keyboards, and each variety has its own properties and unique feel.
And on the subject of key switches, this particular keyboard built with the brown variety of the Cherry MX switches, and ASUS offers the option of Cherry MX Black, Blue, and Red switches with the STRIX TACTIC PRO as well. Our own Scott Michaud covered the topic of key switches in great detail last year, and that article is a great starting point that helps explain the different types of switches available, and how they differ.
The Cherry MX Brown switch in action
I'll go into the feel of the keyboard on the next page, but quickly I'll say that MX Brown switches have a good feel without being too "clicky", but they are certainly more stiff feeling than a typical membrane keyboard. While it's impossible to really describe how the keyboard will feel to a particular user, we can certainly cover the features and performance of this keyboard to help with a purchasing decision in this crowded market. At $150 the STRIX TACTIC PRO carries a premium price, but as you'll see this is also a premium product.
Flagship. Premium. Best in class. These are the terms that Dell and Intel muttered to me during a conference call to discuss the new Dell Venue 8 7000 tablet. It’s a bullish claim and one that would likely have been received with a sideways eye roll or a shrug had I not been able to get a short amount of hands on time with the device at CES in January. The idea that Dell would develop an Android tablet that bests what more established brands like Nexus and Samsung have created, AND that that same tablet would be powered by an Intel processor rather than a Qualcomm, NVIDIA or Samsung chip would have seemed laughable last year. But after a solid three weeks with the Venue 8 7000 I am prepared to make the statement: this is my favorite tablet. Not my favorite Intel tablet, not my favorite Android tablet: just plain favorite.
The Venue 8 7000 combines style, design, technology and visuals that are simply unmatched by anything else in the Android word and rivals anything that Apple has created to date. There are a couple of warts that center around the camera and gaming performance that won’t drop your jaw, but for the majority of use cases the user experience is as exceptional as the looks.
Maybe best of all, this tablet starts at just $399 and is available today.
Dell Venue 8 7000 Specifications
Let’s begin the review by looking at the raw specifications of the Dell Venue 8 7000. Even though hardware specifications don’t tell a complete story of any device, especially a tablet that is based so much on experience, it is important to get a good baseline expectation.
|Dell Venue 8 7000 (Model 7840)|
|Processor||Intel Atom Z3580 Quad-Core 2.33 GHz|
|Screen||2560x1600 OLED 8.4-in (359 ppi)|
MicroSD Slot (up to 512GB)
|Camera||8MP Rear + Dual 720p Depth
|Wireless||Intel 7260 802.11ac 1x1 Dual Band
|Connection||USB 2.0 (power and data)
|Dimensions||215.8mm x 124.4mm x 6mm
8.5" x 4.88" x 0.24"
The center of the Venue 8 7000 is the Intel Atom Z3580 quad-core processor with a peak clock rate of 2.3 GHz and a base clock rate of 500 MHz. The Z3580 is a 22nm processor based on the Moorefield platform and Silvermont architecture. I first got information about the Silvermont architecture back in May of 2013 so it seems a bit dated in some regards, but the performance and power efficiency is still there to compete with the rival options from ARM.. The Venue 8 7000 includes an LPDDR3-1600 controller and there is 2GB of memory; a decent amount but we are seeing quite a few smartphones with more system memory like the OnePlus One.
Introduction and Features
Our first Corsair power supply up for review in 2015 is the CS Series Modular 850W PSU; the CS850M. Corsair's CS Series Modular PSUs are designed for basic desktop use and light to moderate gaming where low energy use, low noise, simple installation, and good value are important. The Modular CS Series now includes five models; the CS450M, CS550M, CS650M, CS750M, and the new CS850M. All of the power supplies in the CS Series feature modular cables, high efficiency (80 Plus Gold certified) and quiet operation. In addition, Corsair continues to offer a full line of high quality power supplies, memory components, cases, cooling components, SSDs and accessories for the PC market.
Here is what Corsair has to say about their CS Series Modular PSUs: “The CS-M Series is designed for basic and midrange PCs, but offers features and performance traditionally reserved for higher-end models. 80 Plus Gold efficiency and a thermally controlled fan ensure quiet operation and lower energy use, and the modular, detachable cable set makes installations and upgrades faster and better looking.”
“80 Plus Gold efficiency reduces operating cost and excess heat. Since it generates less heat, the fan doesn’t need to work as hard, and you’ll enjoy near silent operation. The flat black modular cables with clearly-marked connectors make installation fast and straightforward, with good-looking results.”
