Amped Wireless R20000G and UA2000 Introduction

Continuing with our networking adapter and router reviews, today we have a pair of devices on tap from a relative newcomer to the home and office networking field, Amped Wireless.  Founded in 2007, they began selling Wi-Fi products in 2010.  In those 2 years they’ve already pushed out a wide array of Routers, Range Extenders, Access Points, USB Adapters and Antennas/Boosters.  While they don’t have the history of Cisco, Netgear or D-Link, it’s great to see new companies entering the fray as more competition can only benefit the consumer.

As part of their Black Extreme line of motherboards, the ECS Z77H2-AX pairs the promise of performance and a mile-long feature list with looks that could kill. We decided to put this board through the paces, throwing our normal suite of benchmark and functionality tests to see how well it lived up to its reputation. The ECS Z77H2-AX seems to be well priced at its $309.99 base price with all the higher-end features and bling built into the board.

From the initial unboxing of the board, I was dumbstruck. ECS literally gold-plated every heat-producing surface on this board, giving it a very unique look and feel. The board itself has no shortage of features with SATA 2, SATA 3, mSATA, and eSATA ports, support for 3 different networking types, and enough USB 2.0 and 3.0 ports for anyone.

SilverStone ST45SF-G 450W PSU

Here is what SilverStone has to say about the ST45SF-G: "After successfully expanding and leading SFF (Small Form Factor) cases and SFX PSU into the DIY market, SilverStone engineers have continued their push for advancement in these categories by releasing a true upgrade-worthy small form factor power supply, the ST45SF-G. Despite being half the size of regular ATX power supply, the ST45SF-G can still produce continuous power output of 450W. Its 80 Plus Gold level efficiency is a great leap from the previous SFX best of 80 Plus Bronze and the full modular cables are also the first of its kind for this form factor. To enable users to easily take advantage of this excellent SFX power supply, an adapter is included to convert the ST45SF-G to mount in any ATX case in addition to ones designed for only SFX. For SFF users and for SilverStone, the ST45SF-G is more than just an upgrade, it is an important milestone for DIY desktop computer users."

SilverStone ST45SF-G Main Features:
• Supports standard SFX form factor and ATX (via included bracket)
• 450W continuous power output at 40°C and rated for 24/7 operation
• 80 PLUS Gold level efficiency (87%~90% efficiency at 20%-100% load)
• 100% Modular cables
• Class-leading single +12V rail with 37A capacity
• Strict ±3% voltage regulation with low ripple & noise
• Silent running 80mm fan (18dBA minimum)
• Single PCI-E 8-pin and dual PCI-E 6-pin connectors

Specifications and Outside Features

In recent weeks we have been getting a lot of requests for system reviews, but when ORIGIN PC approached us about testing a super-high-end system with dual NVIDIA GeForce GTX 690s, we were definitely interested.  When we were told to expect a 4.9 GHz Sandy Bridge-E platform to base those Quad SLI GPUs on, we were sold. 

ORIGIN PC has been around since 2009 when several people started the company after leaving Alienware.  While boutique computer builders are still fairly common in today's market, ORIGIN tries to differentiate with ideas like lifetime (yes, lifetime) phone and forum support for your system, lifetime labor for upgrades and services and 72 hours of burn in testing on each machine. 

00.png

The rig we are looking at today falls under the Genesis brand and is the highest end starting point for a custom PC from ORIGIN.  Options for this series include Sandy Bridge-E, Ivy Bridge and even AMD FX processors all with water cooling, multi-GPU configurations and of course, fancy lighting.

Here is a quick overview of the most prominent specs:

  • Corsair 800D chassis
  • Intel Core i7-3930K 6-core Sandy Bridge-E @ 4.9 GHz
  • Intel DX79SR Motherboard
  • Dual NVIDIA GeForce GTX 690 4GB cards (Quad SLI)

Overview

Today we are taking a look at MSI’s flagship Z77 motherboard, the Z77A-GD80. Beyond being the GD80 SKU, which for several generations now has been given MSI’s premiere options, this GD80 in particular is an innovative board. This is due to the Z77A-GD80 being the first Windows motherboard that was certified for Intel’s Thunderbolt technology.

A simple device for a complex problem

Sometimes an odd product finds its way into our office and this week we have one of those very items.  The xPrintServer Home from Lantronix is a networking device that easily configures existing printers on your home or office network to work with the AirPrint capability on your iPhone, iPad and iPod Touch.  It does this without the need for special applications on your phone, without having to buy new printers and without complex software based work arounds.

04.jpg

The unit itself is a small white plastic case that has an Ethernet connection, USB port and power connection.  The Ethernet port needs to be connected to your router / switch and the USB port is for connecting one of more USB printers (via a USB hub).  After attaching the power, the device goes through an incredibly simple, automatic configuration process. 

01.jpg

After the orange light goes solid, you can simply go to an AirPlay enabled application like Safari, Photos, Notes, Mail and more and hit the print option; your network or USB printer should already be configured.  The process is impressively easy!

03.jpg

Inside the device is a basic Atmel designed ARM926 core SoC running at 400 MHz - more than enough power for the print spooling that it does on the Lantronix device.

By far the most impressive part about the xPrintServer is the ease of setup; we were literally up and printing on an iPhone 5 within 2 minutes of opening the box.  If you are the kind of person that would like the capability to print from your iPad or iPhone but without having to buy a new printer with AirPrint built in, definitely check out this product. 

You can currently find the Lantronix xPrintServer Home for $95 at Newegg.com.

Introduction, Specifications and Packaging

Introduction

It's been a short while since we've seen a consumer SSD release from Intel, and with pressure coming from Samsung in the form of lower cost/GB 20nm flash, it was high time Intel followed suit. The Intel 335 Series launches today, and is essentially the same SandForce-driven product as their SSD 520 Series released earlier this year. The key change is this time around that controller will be driving Intel 20nm flash. This should bring a much needed price reduction to the SSD arena, as the 335 is not being marketed as a 'Pro' unit (like the Samsung's 840 Pro). So long as this new model performs similarly to the 520 Series, we should be in for a good, low cost SSD just in time for the Christmass shopping season.

Windows RT: Runtime? Or Get Up and Run Time?

Update #1, 10/26/2012: Apparently it does not take long to see the first tremors of certification woes. A Windows developer by the name of Jeffrey Harmon allegedly wrestled with Microsoft certification support 6 times over 2 months because his app did not meet minimum standards. He was not given clear and specific reasons why -- apparently little more than copy/paste of the regulations he failed to achieve. Kind-of what to expect from a closed platform... right? Imagine if some nonsensical terms become mandated or other problems crop up?

Also, Microsoft has just said they will allow PEGI 18 games which would have received an ESRB M rating. Of course their regulations can and will change further over time... the point is the difference between a store refusing to carry versus banishing from the whole platform even for limited sharing. The necessity of uproars, especially so early on and so frequently, should be red flags for censorship to come. Could be for artistically-intentioned nudity or sexual themes. Could even be not about sex, language, and violence at all.

***

Last month, I suggested that the transition to Windows RT bares the same hurdles as transitioning to Linux. Many obstacles blocking our path, like Adobe and PC gaming, are considering Linux; the rest have good reason to follow.

This month we receive Windows RT and Microsoft’s attempt to shackle us to it: Windows 8.

Windows95.png

To be clear: Microsoft has large incentives to banish the legacy of Windows. The way Windows 8 is structured reduces it to a benign tumorous growth atop Windows RT. The applications we love and the openness we adore are contained to an app.

I will explain how you should hate this -- after I explain why and support it with evidence.

Microsoft is currently in the rare state of sharp and aggressive focus to a vision. Do not misrepresent this as greed: it is not. Microsoft must face countless jokes about security and stability. Microsoft designed Windows with strong slants towards convenience over security.

That ideology faded early into the life of Windows XP. How Windows operates is fundamentally different. Windows machines are quite secure, architecturally. Con-artists are getting desperate. Recent attacks are almost exclusively based on fear and deception of the user. Common examples are fake anti-virus software or fraudulent call center phone calls. We all win when attackers get innovative: survival of the fittest implies death of the weakest.

Bulldozer to Vishera

 

Bulldozer is the word.  Ok, perhaps it is not “the” word, but it is “a” word.  When AMD let that little codename slip some years back, AMD enthusiasts and tech journalists started to salivate about the possibilities.  Here was a unique and very new architecture that promised excellent single thread performance and outstanding multi-threaded performance all in a package that was easy to swallow and digest.  Probiotics for the PC.  Some could argue that the end product for Bulldozer and probiotics are the same, but I am not overly fond of writing articles containing four letter colorful metaphors.

vish_01.jpg

The long and short of Bulldozer is that it was a product that was pushed out too fast, it had specifications that were too aggressive for the time, and it never delivered on the promise of the architecture.  Logically there are some very good reasons behind the architecture, but implementing these ideas into a successful product is another story altogether.  The chip was never able to reach the GHz range it was supposed to and stay within reasonable TDP limits.  To get the chip out in a timely manner, timings had to be loosened internally so the chip could even run.  Performance per clock was pretty dismal, and the top end FX-8150 was only marginally faster than the previous top end Phenom II X6 1100T.  In some cases, the X6 was still faster and a more competent “all around” processor.

There really was not a whole lot for AMD to do about the situation.  It had to have a new product, and it just did not turn out as nicely as they had hoped.  The reasons for this are legion, but simply put AMD is competing with a company that is over ten times the size, with the resulting R&D budgets that such a size (and margins) can afford.  Engineers looking for work are a dime a dozen, and Intel can hire as many as they need.  So, instead of respinning Bulldozer ad nauseum and releasing new speed grades throughout the year by tweaking the process and metal layer design, AMD let the product line sit and stagnate at the top end for a year (though they did release higher TDP models based on the dual module FX-4000 and triple module FX-6000 series).  Engineers were pushed into more forward looking projects.  One of these is Vishera.

A curious new driver from AMD

In case you missed the news, AMD is going to be making a big push with their Radeon brand from now until the end of the year starting with an incredibly strong game bundle that includes as many as three full games and 20% off the new Medal of Honor.  The second part of this campaign is a new driver specifically the 12.11 beta that will be posted to the public later this week.

04.jpg

AMD is claiming to have made some substantial improvements on quite a few games including the very popular Battlefield 3 and the upcoming Medal of Honor (both of which use the same base engine).  But keep in mind that 15% is a LOT and this is the best case scenario in specific maps and you may not see benefits on others. 

There are going to be some debates about the validity of these performance boosts from AMD until we can get some more specific details on WHAT has changed.  Essentially the company line is that they have finally "caught up" to the GCN GPU architecture introduced with the Radeon HD 7970 in January of 2012.  We traditionally see this happen with new GPU architectures from both vendors but for it to have taken this long is troublesome and will surely cause some raised eyebrows from gamers and the competition. 

We decided to run through the Radeon HD 7870 GHz Edition with this new 12.11 beta driver to compare it to the 12.9 beta driver we had just completed testing on a few weeks ago.  AMD claims performance advantages for all the GCN cards including the 7700/7800/7900 cards though we only had time to test a single card for our initial article.  The results are on the following pages...

Product Overview

Some computer components get all the glory.  Your normal lineup of FPS crushing GPU’s, Handbrake dominating CPU’s, and super-fast Memory end up with most of the headlines.  Yet behind the scenes, there are some computer components we use that are pivotal in our use and enjoyment of computers and receive very little fanfare.  Without networking we wouldn’t have file sharing, LAN parties or even the Internet itself.   Without routers and network adapters, we wouldn’t have networking.

ASUS recently sent a whole slew of networking components our way and we’ve decided to take them for a spin and see if they’re worth your hard earned dollars.  Our box of ASUS goodies included:

  • ASUS RT-N66U Gigabit Router – Dual Band Wireless-N900
  • ASUS PCE-N10 - Wireless N PCI-E Adapter Wireless-N
  • ASUS PCE-N15 - Wireless N PCI-E Adapter Wireless-N
  • ASUS USB-N53 - Dual Band Wireless N Adapter
  • ASUS USB-N66 - Dual Band Wireless-N900 Adapter

Without further ado, let’s jump in and tackle each one.

ASUS RT-N66U Gigabit Router – Dual Band Wireless-N900

Routers are one of those components that most of us don’t really think about unless something goes horribly wrong.  Most people will buy one they find on a big box store shelf (or even worse, just use their ISP’s router), pull it out of the box, plug a few cables into it and then forget about it in a closet for a few years.

A look outside and in

We handle a fair amount of system reviews here at PC Perspective and use them mainly as a way to feature unique and interesting designs and configurations.  We know how the hardware will perform for the most part; doing extensive CPU and GPU testing on nearly a daily basis.  Sometimes we'll get systems in that are extremely budget friendly, other times vendors pass us machines that have MSRPs similar to a Kia automobile.  Then there are times, like today, we get a unique design that is a great mix of both.

AVADirect has had a Mini Gaming PC design for a while now but recently has gone through a refresh that adds in support for the latest Ivy Bridge processors, NVIDIA Kepler GPUs all using a new case from BitFenix that combines it in a smaller, mini-ITX form factor.

The quick specifications look like this:

  • BitFenix Prodigy chassis
  • Intel Core i7-3770K CPU, Overclocked at 4.4 GHz
  • ASUS P8Z77-I Deluxe Z77 Motherboard
  • EVGA GeForce GTX 680 2GB GPU
  • OCZ 240GB Vertex 3 SSD
  • Seagate 2TB SATA 6G HDD
  • 8GB Crucual DDR3-1866 Memory
  • Cooler Master 850 watt Silent Pro PSU

You'll also see a large, efficient Prolimatech cooler inside along with a Blu-ray burner and Windows 7 for a surprisingly reasonable $2100 price tag.

01.jpg

The BitFenix Prodigy chassis is a unique design that starts with sets of FiberFlex legs and handles surrounding the mini-ITX case.  The minor flexibility of the legs absorbs sound and impact on the table while the handles work great for picking up the system for LAN events and the like.  While at first I was worried about using them to support the weight of the rig, I had no problems and was assured by both BitFenix and by AVADirect it would withstand the torture.

Wireless storage for PC, Mac, iOS and Android

Today we are taking a look at the new Patriot Gauntlet 320 external USB 3.0 and wireless hard drive, available starting at $149 at Newegg.com.

Gauntlet_320_Pkg_Left.jpg

The premise is quite simple: take a portable hard drive with USB 3.0 support and add in the ability to share the unit wirelessly with up to 8 different machines and power it by a lithium-ion battery.  Not only does the Gauntlet show up in your network as a mountable drive in Windows and Mac OS, the Gauntlet supports using free applications for iOS devices and Android devices to share and stream media.

Gauntlet_320-Left.png

There are some limitations that you might want to consider including the inability to access network-based devices when using the pass through Internet capability the Gauntlet provides.  Also, data transfer performance on the wireless connectivity that the Gauntlet provides seemed pretty low, even with the 802.11n support. 

Potential uses cases for the Gauntlet include any time you need a shared data source like working on group projects for school or the office, on-the-go storage for devices like Ultrabooks with smaller hard drives and users that have large media collections they want to use with smart phones and tablets.

Check out our full video review below!

Note that in the video, our early sample of the Gauntlet 320 has the "node" label on it; the Gauntlet Node is a separate device that is only a DIY enclosure WITHOUT an included hard drive.  Originally there was a sticker cover the "node" label but incorrectly removed it before filming.  Just a heads up!

And Why the Industry Misses the Point

3d_01_title2.png

I am going to take a somewhat unpopular stance: I really like stereoscopic 3D. I also expect to change your mind and get you excited about stereoscopic 3D too - unless of course a circumstance such as monovision interferes with your ability to see 3D at all. I expect to accomplish where the industry has failed simply because I will not ignore the benefits of 3D in my explanation.

Firstly - we see a crisp image when our brain is more clearly able to make out objects in a scene.

We typically have two major methods of increasing the crispness of an image: we either increase the resolution or we increase the contrast of the picture. As resolution increases we receive a finer grid of positional information to place and contain the objects in the scene. As contrast increases we receive a wider difference between the brightest points and the darkest points from a scene which prevents objects from blending together in a mess of grey.

We are also able to experience depth information by comparing the parallax effect across both of our eyes. We are able to encapsulate each object into a 3D volume and position each capsule a more defined distance apart. Encapsulated objects appear crisper because we can more clearly see them as sharply defined independent objects.

Be careful with this stereoscopic 3D image. To see the 3D effect you must slowly cross your eyes until the two images align in the center. This should only be attempted by adults with fully developed eyes and without prior medical conditions. Also, sit a comfortable distance away so you do not need to cross your eyes too far inward and rest your eyes until they no longer feel strained. In short - do not pull an eye muscle or something. Use common sense. Also move your mouse cursor far away from the image as it will break your focusing lock and click on the image to make it full sized.

3d_03.png

Again, be careful when crossing your eyes to see stereoscopic 3D and relax them when you are done.

The above image is a scene from Unreal Tournament 3 laid out in a cross-eyed 3D format. If you are safely able to experience the 3D image then I would like you to pay careful attention to how crisp the 3D image appeared. Compare this level of crispness to either the left or right eye image by itself.

Which has the crisper picture quality?

That is basically why 3D is awesome: it makes your picture quality appear substantially better by giving your brain more information about the object. This effect can also play with how the brain perceives the world you present it: similar to how HDR tonal mapping plays with exposure ranges we cannot see and infrared photography plays with colors we cannot see to modify the photograph - which we can see - for surreal effects.

So what goes terribly wrong? Read on to the article to find out.

Introduction and Internals

Introduction:

The Western Digital RAID Edition line of hard drives has been around for some time now, and has largely impressed us with each subsequent release. Since the launches of the RE4-GP and later, the faster spinning RE4, WD's enterprise line had been capped at the 2TB mark. Now that has changed with the introduction of a new line: simply named the RE Series:

121010-163545-4.8.jpg

Yup, that's right. 4 TeraBytes! With the Green and Red series capped at 3TB, this new RE is the largest capacity drive available from Western Digital. The catch is that, since it's tailored and built for enterprise use, it comes at a rather hefty price premium.

Another GK106 Completes the Stack

It has been an interesting year for graphics cards and 2012 still has another solid quarter of releases ahead of it.  With the launch of AMD's 7000-series back in January, followed by the start of NVIDIA's Kepler lineup in March, we have had new graphics cards on a very regular basis ever since.  And while AMD's Radeon HD 7000 cards seemed to be bunched together a bit better, NVIDIA has staggered the release of the various Kepler cards, either because of capacity at the manufacturing facilities or due to product marketing plans - take your pick. 

Today we see the completion of the NVIDIA GeForce GTX 600 stack (if you believe the PR at NVIDIA) with the release of the GeForce GTX 650 Ti, a $150 graphics card that fills in the gap between the somewhat anemic GTX 650 and GT 640 cards and the most recently unveiled card, the GTX 660 2GB that currently sells for $229. 

01.jpg

The GTX 650 Ti has more in common with the GTX 660 than it does the GTX 650, both being based on the GK106 GPU, but is missing some of the unique features that NVIDIA has touted of the 600-series cards like GPU Boost.  Let's dive into the product and see if this new card will be the best option for those of you with $150 graphics budgets.

I have been in several situations where a variety of people claim the gamepad is superior for gaming because that is what it was designed for. No elaboration or further justification is given. The controller is designed for gaming and is therefore clearly better. End of – despite often being start to – discussion in their minds.

Really it is a compromise between the needs of popular games and the environment of a couch.

Interface design is complicated. When you design an interface you need to consider: the expected types of applications; the environment of the user; what you are permitted to use; what tolerances are allowed; what your audience is used to; and so on, so forth. There is a lot to consider when you design an application for a user and I could make an educated guess that it is at least as hard to design the input device itself.

The history of keyboard design is a great example of tradeoffs in input devices.

Sometimes it is better to be worse...

The first wave of keyboards were interfaces to the mechanical typewriter. These keyboards were laid out in alphabetical order because as long as each key is accessible and the user could find the letter they wanted – who cares, right? We already have an order for the alphabet that people understands so the users should not have too much difficulty in finding the letter they need.

Another constraint quickly game to light: typists were too fast and the machines jammed.

The engineers now needed to design an input method which could keep up with the typist. Correcting the machine itself was somewhat futile so the solution was to make the typist as slow as possible. The most common letters in the English language were spread all over the place and – while possibly by fluke – the left hand is favored, as in made do more work, over the often dominant right hand.

The problem required making the most aggravating keyboard layout engineers could imagine. QWERTY was born.
