Zotac recently launched a new line of tiny ZBOX PCs under the new R Series that support two drive RAID 0 and RAID 1 setups. The series currently includes the ZBOX 1323 and ZBOX R1531. Both systems can be mounted vertically or horizontally and strongly resemble the company's existing ZBOX computers. The top and bottom panels are black with a silver bezel around the sides. A Zotac logo sits in the corner and a large blue circle sits in the center of the top.
The front panel hosts two audio jacks, an SDXC ard reader, COM port, IR reciever, and power button. Around back, the ZBOX boasts two antennas for the internal wireless module, two Gigabit Ethernet jacks, two USB 3.0 ports, and DisplayPort and HDMI video outputs. A third USB 3.0 port sits along the top edge of this small form factor PC.
Internally, Zotac is using Intel processors, a small form factor motherboard with two SO-DIMM slots (up to 16 GB), a Mini PCI-E slot for the 802.11ac (plus Bluetooth 4.0) wireless card, and support for up to two 2.5" SATA drives. The motherboard supports RAID 0, RAID 1, and JBOD configurations for the SATA drives, and the R1531 SKU adds a mSATA slot for a third drive.
The ZBOX R1323 is equipped with a 11.5W dual core Intel (Haswell) Celeron 2961Y processor clocked at 1.1 GHz with 2MB cache and Intel HD Graphics clocked at up to 850 MHz. The ZBOX R1531 steps up to a 15W dual core (plus Hyperthreading) Broadwell-based Intel Core i3-5010U clocked at 2.1 GHz with HD 5500 graphics clocked at up to 900 MHz.
Both versions will be offered as barebones systems and the R1531 is additionally be sold in a PLUS model that comes with a 64GB mSATA SSD and 4GB of RAM pre-installed.
The new ZBOX R Series PCs would make for a nice home server with a mSATA drive for the OS and two storage drives in a RAID 1 for redundancy. The Core i3 should be plenty of horsepower for streaming media, running backups, running applications, and even some light video transcoding. The included COM port will also make it suitable for industrial applications, but I think this is mostly going to appeal to home and small business users.
Zotac has not yet revealed pricing or availability though. Hopefully we are able to find out more about these mini PCs at Computex!

Reports around the web along with this Intel PDF point to the official launch of a new low power NUC coming next month. The NUC5CPYH and NUC5PPYH are powered by Braswell-based Intel Celeron and Pentium processors topping out at 6W TDPs.
These new NUC models have room for a motherboard, Braswell processor, a single laptop memory slot, a Mini PCI-E slot for the wireless module, and one 2.5" hard drive or SSD. There is no support for mSATA here which likely helped Intel cut costs (and as Olivier from FanlessTech points out mSATA support was dropped around the time of NUC 2.0). Further, unlike the lower power (4W versus 6W TDP) Braswell-based ASRock PC (which is also SFF but not a NUC), the two Intel NUCs are surely actively cooled by a fan.
On the outside of the compact PC, users have access to two USB 3.0 ports (one charging capable 5V/3A), a headphone/mic jack, infrared receiver, and SDXC memory card reader on the front. The rear panel hosts an additional two USB 3.0 ports, HDMI output, Gigabit LAN port, and optical audio output. The PC also has a Kensington lock port and is VESA moutable.
Internally, Intel has opted for two of the highest power Braswell processors, the Intel Celeron N3050 and Intel Pentium N3700. Both are 14nm chips with a 6W TDP with Airmont CPU cores and Intel HD Graphics. The N3050 is a dual core part clocked at up to 2.16 GHz (1.6 GHz base) with 2MB cache and HD Graphics clocked between 320 and 600 MHz. The Pentium N3700 model on the other hand features four CPU cores clocked at up to 2.4 GHz (1.6 GHz base) paired with HD Graphics clocked at 700 MHz (400 MHz base).
Both the NUC5CPYH and NUC5PPYH will reportedly be available on June 8th starting at $140 and $180 respectively. This is an interesting price point for NUCs though it's popularity is going to heavily depend on the Braswell CPU's performance especially with Bay Trail-powered versions still on the market for even less (though with less performance).

Tagged: thinkpad tablet 10, thinkpad tablet, Thinkpad, Lenovo
The announcements keep rolling in here at Lenovo’s first Tech World event here in Beijing, starting off with a next generation version of their ThinkPad Tablet 10.
The 2015 version of the ThinkPad Tablet 10 is based around Intel’s new Cherry Trail SoC platform in form of the Atom Z8500 and Z8700. Alongside the Atom SoC, the Tablet 10 will sport either 2GB or 4GB of RAM depending on the configuration, although it is unclear if the 4GB option will only be available with the Z8700 option. 64-bit support will also be found with the Tablet 10 thanks to Cherry Trail’s support for 64-bit operations as opposed to the previous generation Bay Trail.
The ThinkPad Tablet 10 marks the first integration of Lenovo’s WRITEit software, which they claim allows for easier handwriting input across the entire Windows OS. While we haven’t had hands on with the final version, the tech preview of this that we saw at CES was very promising and looks to be a better solution than the native Windows 10 handwriting support.
Lenovo was also eager to mention that they’ve seen wide adoption with the current ThinkPad Tablet 10 in fields such as large enterprises, airlines and hospitals. In light of this, the Tablet 10 will support technologies such as dTPM for trusted computing, NFC, as well as biometric authentication, and optional Smart Card support.
The Lenovo ThinkPad Tablet 10 is set to launch at the start of August, in the same time frame of Windows 10.

The Shuttle DS57U is powered by a dual core Celeron 3205U running at 1.5GHz and a nice and cool 15W TDP. The system supports up to 16GB of DDR3 at 1.35 V, no 1.5V DIMM that TechPowerUp tried would work and for add-in cards you have a single full sized mini-PCIE slot and a half sized mini-PCIE slot which is already occupied by a WLAN card. The system does have only one SATA 6Gbps port so external storage may be necessary, thankfully there are a pair of USB 3.0 ports and four USB 2.0 ports. This model is available for $250 currently, if you decide you need more power there are several versions going all the way up to the DS57U7 powered by an i7-5500U. If you are looking for an inexpensive SFF barebones system, Shuttle is not a bad choice overall and the DS57U is worthy of consideration.
"The Shuttle DS57U is a slim barebone PC that only needs RAM and a HDD or, even better, an SSD to boot. It comes with an Intel dual-core Celeron processor (Broadwell) and features lots of I/O ports, which make it suitable for a wide range of applications."

Tagged: SFF, nuc, Intel, fanless, Cherry Trail, Braswell, asrock
Earlier this month, ASRock showed off a tiny fanless computer it is calling the Beebox. Powered by an Intel Braswell SoC, the new small form factor Beebox offers up a decent selection of I/O ports and general desktop performance while sipping power. The Beebox is approximately the size of Intel's NUC measuring 118.5mm x 110mm x 46mm x (4.67" x 4.33" x 1.81" -- WxDxH) and will come in three color options: black, gold, and white.
This compact PC has a fairly extensive set of ports on tap. The front panel includes a headphone jack, infrared port, one standard USB 3.0 port, and a USB 3.0 Type-C port which supports 5V/3A charging. The rear panel hosts the power jack, two HDMI outputs, one DisplayPort output, two USB 3.0 ports, a Realtek-powered Gigabit Ethernet port, and a Kensington lock slot. Not bad for a small form factor PC.
ASRock will be offering the Beebox in three configuration options including a barebones kit, a version with 32 GB internal storage, 2 GB of RAM, and Windows 10, and a Beebox SKU with 128 GB of internal storage and 4 GB of RAM (and no OS pre-installed). Each of the SKUs are powered by the same Intel Celeron N3000 Braswell SoC. From there, users can add a single 2.5" SATA drive and a Mini PCI-E card (although this slot is occupied by the included 802.11ac Wi-Fi and Bluetooth 4.0 wireless module). The system uses two DDR3L SO-DIMMs and supports a maximum of 8 GB DDR3L at 1600 MHz.
The aspect that made the Beebox stand out to me was the inclusion of the Braswell-based Celeron N3000 processor. This 4W 14nm part features two Airmont CPU cores clocked at 1.04 GHz base and 2.08 GHz turbo paired with 2MB L2 cache and a Gen 8 Intel GPU clocked at up to 600 MHz. This is a desktop variant of the Cherry Trail chips being used in tablets, but it is the lowest TDP Braswell chip currently at a mere 4 watts. ASRock likely went with this chip to ensure they could passively cool it and still keep temperatures in check. As FanlessTech notes, the chassis ASRock is using leaves a lot to be desired when it comes to heat dissipation compared to other fanless cases on the market.
We will have to wait for reviews to see how well the Beebox and its Braswell processor perform, but so long as ASRock is able to keep thermals in check, the little PC should offer acceptable performance for general desktop tasks (browsing the internet, checking email, watching streaming videos, etc). Cherry Trail (and keep in mind Braswell is a higher power chip based on the same architectures) is promising noticeable improvements to graphics and at least slight improvements to CPU performance. According to ASRock, the Beebox is going to be priced aggressively at "very low" price points which should make it a good compromise between older Bay Trail-D systems and newer (and more expensive) Broadwell and Haswell systems.
The Beebox is slated for late June availability, with exact pricing to be announced at that time.

Tagged: Oculus, oculus vr, nvidia, amd, geforce, radeon, Intel, core i5
Today, Oculus has published a list of what they believe should drive their VR headset. The Oculus Rift will obviously run on lower hardware. Their minimum specifications, published last month and focused on the Development Kit 2, did not even list a specific CPU or GPU -- just a DVI-D or HDMI output. They then went on to say that you really should use a graphics card that can handle your game at 1080p with at least 75 fps.
The current list is a little different:
- NVIDIA GeForce GTX 970 / AMD Radeon R9 290 (or higher)
- Intel Core i5-4590 (or higher)
- 8GB RAM (or higher)
- A compatible HDMI 1.3 output
- 2x USB 3.0 ports
- Windows 7 SP1 (or newer).
I am guessing that, unlike the previous list, Oculus has a more clear vision for a development target. They were a little unclear about whether this refers to the consumer version or the current needs of developers. In either case, it would likely serve as a guide for what they believe developers should target when the consumer version launches.
This post also coincides with the release of the Oculus PC SDK 0.6.0. This version pushes distortion rendering to the Oculus Server process, rather than the application. It also allows multiple canvases to be sent to the SDK, which means developers can render text and other noticeable content at full resolution, but scale back in places that the user is less likely to notice. They can also be updated at different frequencies, such as sleeping the HUD redraw unless a value changes.
The Oculus PC SDK (0.6.0) is now available at the Oculus Developer Center.

Okay, so some people are drawing parallels between this and Lenovo's Superfish scandal that happened late last year and carried on for the first few months of 2015. I am not a fan of that comparison. In the case of Superfish, Lenovo added third-party software that tampered with security for the purpose of advertising on the user's machine. In this case, a first-party application has a remote code execution vulnerability that was dealt with responsibly.
This happens to pretty much everyone, regularly.
But, so our readers know, they should update their Lenovo System Update. The current version, which seems to be 18.104.22.168 as far as I can tell, has been available since April and is not affected. This bug only concerns 22.214.171.124 and earlier. The issues were discovered in February by IOActive and disclosed to the PC manufacturer, who updated them before the security company published the issue. Unless I'm missing something, this is how it is supposed to be done.

Falcon Northwest recently upped the hardware ante on its small form factor Tiki PC. Previously limited to Z97-based hardware, the company is now offering Tiki PCs with X99 motherboards. Even better, the Tiki can be configured with Intel’s Haswell-E Core i7-5000 or Haswell-EP Xeon chips such as the Core i7-5960X or Xeon E5-2699V3.
The updated Tiki maintains the same steel and aluminum case measuring 13” x 4” x 13” (HxWxD) with customizable paint work and a removable solid aluminum or granite base as its predecessors (e.g. Tiki-Z). External I/O options include the latest USB 3.1, eSATA, and Dual Intel Gigabit LAN ports. Internally, the Tiki has space for an Intel Z97 or X99 motherboard with a liquid cooled processor, up to 32GB of DDR4 (or 16GB DDR3 with Z97) memory, a dedicated graphics card up to an NVIDIA GTX TITAN X or Quadro and ample storage space in the form of four 2.5” drives or one 3.5” and two 2.5” drives.
All this hardware amounts to an impressive amount performance in general – much less a small form factor system. At the upper echelon, the Xeon E5-2699V3 offers 18 cores (36 threads with HT) clocked at up to 3.6 GHz paired with 45MB of L3 cache. Paired with a Quadro card like the M6000, that is one powerful workstation!
The updated Tiki is aimed at gamers and workstation builds doing intensive workloads like CAD, 3D animation, and video production.
The downside to this stylish powerhouse is, of course, pricing – the Tiki is far from cheap and the boutique premium is quite evident here. Available now, the updated Tiki starts at $1,860 for a base level Z97 system with quad core CPU or $2,492 for an eight core X99-based system. Fully loaded, the Tiki tops $10,000.
It is definitely an extremely niche product, but the engineering and styling is impressive all the same!

When Sebastian reviewed the LIVA X he focused on the performance of the device as an HTPC running Ubuntu ... before attempting to determine its effectiveness in creating a peanut butter and banana omelette, but that is a different story.
Overclocker's Club took a different tack, examining how it would perform for light gaming duties. On default settings the LIVA X managed 517 in Sky Diver, 1198 in Cloud Gate, 14200 in Ice Storm, and 9598 in Ice Storm Extreme. This would make it effective at playing mobile games or even playing through legacy games available through GoG or the Internet Archive; they tested CivV as a more modern title and while playable it wasn't great. Check out the full review for the other benchmark results.
"The ECS LIVA X surprised me with its small size and completely silent operation. I was able to surf the internet and do work on it very quickly. I enjoyed using it and experienced no problems with browsing the internet, using Office applications, or watching streaming videos on Netflix. Amazon Prime would occasionally lag a little – usually when the HUD would pop up."

Tagged: Intel, compute stick, Bay Trail-D
Back at CES in January Intel shared with us a preview of the company's latest new platform form factor, the Compute Stick. That's the formal, official name, a follow up from the same team that brought us the NUC (Next Unit of Computing). The Compute Stick is a thumb-drive-shaped, full PC integration that has a physical HDMI connection to plug directly into your TV.
The specifications remain unchanged from what we learned at CES:
The Intel Compute Stick, aptly named, seems to fit somewhere between these two devices. It is an HDMI dongle enclosing an x86, quad-core, computer with 2GB of RAM and 32GB of internal storage. Intel eventually plans to have the device powered by the HDMI port, but it currently requires power over micro USB. Besides power, it also has a standard USB (Type A-Female) port and a micro SD card slot. It also has 802.11n wireless networking inside it. Being a full Windows device, you can stream media, browse the web, and use many other applications on it.
This week the devices have started showing up for pre-order on Newegg.com and even Amazon.com.
- Intel Compute Stick - Win 8.1, 32GB - Newegg.com ($149) - Amazon.com ($149)
- Intel Compute Stick - Linux, 32GB - Newegg.com ($109) - Amazon.com ($109)
Newegg.com has a specific pre-order going but it looks like Amazon is still on the waiting list process. Interestingly, a quick search for "compute stick" on Amazon reveals a host of other very similar devices, the most popular of which are sold as the MeeGoPad Stick with a price tag of ~$109. I'm not sure what those products will ship with when it comes to an operating system and some reviews indicate that the Windows version installed is not activated, so go in at your own risk.
As for the official Intel sold Compute Stick, I'm excited to try one out. The device includes a Bay Trail quad-core CPU, a single micro-USB port for power, a full-sized USB 2.0 port for connectivity (webcam, etc.) as well as a MicroSD slot for storage expansion. The device embeds Wi-Fi (802.11b/g/n) and Bluetooth so you'll be able to connect to a network and get wireless keyboards and mice up and running easily.
The amount of capability you get for $149, including a full copy of Windows 8.1 with Bing, is astounding and, if it lives up the hype, could be a great replacement for a Google Chromecast or a Kindle Fire TV. Look for a review very soon!

Silent PC Review spends a lot of effort choosing components which offer a great performance but do not create a lot of noise and their latest sytem is a perfect example. Even with a pair of air cooled GTX 970's and an i5-4690K this system only hit 23dBA under load, quiet enough for SPCR to confirm their 970's suffer from coil whine. The sound came primarily from the GPUs as you would expect so it is possible that finding a very quiet radiator and watercooling them might reduce the sound produced even further. It just goes to show how much quieter air cooling has become from the days of screaming 40mm Deltas.

Favor a steamier TV gaming experience? ZOTAC has announced a new Steam Machine on the eve of Valve’s presentation at GDC on Wednesday.
The SN970 presumably gets its name from the GTX 970M mobile GPU within, and this does the heavy lifting along with an unspecified 6th-generation Intel (Skylake) CPU. The massive amount of HDMI outputs (there are 4 HDMI 2.0 ports!) is pretty impressive for a small device like this, and dual Gigabit Ethernet ports are a premium feature as well.
There's a lot going on back here - the rear I/O of the ZOTAC SN970
Here's the rundown of features and specs from ZOTAC:
- SteamOS preloaded
- NVIDIA GeForce® GTX 970M MXM graphics
- 4 x HDMI 2.0, supports 4K UHD @ 60Hz
- 6th Gen Intel Processor
- NVIDIA GeForce® GTX 970M 3GB GDDR5
- 8GB DDR3 SODIMM
- 64GB M.2 SSD
- 1 x HDMI in
- 2D/3D NVIDIA Surround
- Dual Gigabit Ethernet
- 4 x USB 3.0, 2 x USB 2.0
- 1 x 2.5” 1TB HDD
- 802.11ac WiFi, Bluetooth 4.0
- Mic-In, Stereo Out
- SD/SDHC/SDXC Card Reader
The release for this new Steam Box isn't specified, but we will be doubtless be hearing more from Valve and their partners tomorrow so stay tuned!

Tagged: spectre x360, spectre, mwc 15, MWC, hp, Broadwell
HP announced their updated Spectre x360 at Mobile World Congress. Like the Lenovo Yoga, it has a hinge that flips the entire way around, allowing the laptop to function as a 13.3-inch tablet with a 1080p, IPS display. There are two stages between “tablet” and “laptop”, which are “stand” and “tent”. They are basically ways to prop up the touch screen while hiding the keyboard behind (or under) the unit. The stand mode is better for hands-free operation because it has a flat contact surface to rest upon, while the tent mode is probably more sturdy for touch (albeit rests on two rims). The chassis is entirely milled aluminum, except the screen and things like that of course.
The real story is the introduction of Core i-level Broadwell. The 12.5-hour battery listing in a relatively thin form-factor can be attributed to the low power requirements of the CPU and GPU, as well as its SSD (128GB, 256GB, or 512GB). RAM comes in two sizes, 4GB or 8GB, which will depend slightly on the chosen processor SKU.
Prices start at $899 and most variants are available now at HP's website.

Ryan just polished off his review of the next generation of Intel NUC, the Broadwell powered NUC5i5RYK in both video and written form but perhaps you still have some questions. If so, or if you are wise enough to prefer a second opinion then you should make time to visit The Tech Report who also received a unit for review. They covered the performance of several indie games, which ran quite well as well as CS:GO which could handle 1600x900 at medium settings. Their conclusion matched Ryan's, not only is this a great HTPC and light gaming machine but for most office purposes this is a perfect solution to present to your users.
"Thanks to the Broadwell-U silicon inside, Intel's new NUC promises better performance and power efficiency than the previous generation. There are other improvements under the hood, too, including the addition of an M.2 storage slot and a built-in Wi-Fi controller."

Tagged: raspberry pi 2, Raspberry Pi
It did not take long to find a problem with the Raspberry Pi 2. As it turns out, the Pi 2 contains a power regulator chip that is susceptible to bright sources of light. The light will force electrons to move when a metal is struck by enough photons with the correct, per-photon energy, which is its frequency/color, and that will be perceived as a voltage (because it actually does cause a voltage).
In the Raspberry Pi 2, this manifests as a voltage drop and the device immediately powers down. This was first discovered by Peter Onion on the Raspberry Pi forums while he was taking photographs of his Raspberry Pi 2. He noticed that each time he snapped a photo, the Pi would shut down. Liz Upton of the Raspberry Pi Foundation promptly confirmed the issue and wrote a long blog post explaining what actually happens. She borrows Peter's joke from the forum thread, that the Pi 2 is camera shy, and explains that “everyday light sources” will not cause this to happen. She then explains the photoelectric effect, the role of the above pictured U16 chip, and the issue itself.
I definitely appreciate Liz Upton and the Raspberry Pi Foundation, founded on the premise of education, taking the time to explain their bugs from an educational standpoint. That said, it is easy to lose sight of your goal when you have a product to defend, and I am glad that it did not get in the way.
A final note: this will not damage the Pi 2, just cause it to crash and power down. The only real problem is that shutting down your device mid-task will crash your task. If that is a write to the SD card, that will likely corrupt that write.

This is just a quick note for a small subset of our audience. If any of our developer-minded readers are in the Phoenix, Arizona region on February 19th, Intel will be hosting a meetup at UAT (the University of Advancing Technology). The processor vendor will perform a technical presentation about the Edison Internet-of-Things (IoT) developer kit. Shortly after the presentation, the group will move to Aunt Chilada's for a social event.
The presentation will take place in the theatre (there is only one as far as I can tell) at 6:30pm. Admission is free and there will be 10 Intel Edison kits to be raffled. Food and beverages will be provided by Intel (at Aunt Chilada's restaurant).
Microsoft Filed for "Windows 365" Trademark in Late January. Jeremy Prepares to File for Windows 340 through 364?
Subject: General Tech, Systems | February 10, 2015 - 12:55 AM | Scott Michaud
Tagged: windows 365, windows 10, windows, office 365, microsoft
While it is trivial for a large corporation to file for a trademark, there are fairly strict guidelines with how they are used (or, more accurately, not-used). Because trademarks can be forever, the law outlines numerous procedures that can classify them as abandoned, which lets Coca Cola be a known, legitimate source of Coca Cola for as long as Coca Cola makes Coca Cola, while preventing businesses from being created that do nothing but license names.
Patents! I'm looking at you!
So the news is that Microsoft filed for the trademark, “Windows 365”. Knowing their trademark on Office 365, people are assuming that this will lead to a subscription version of Windows. The trademark filing is then compared to the statements made by Terry Myerson about Windows as a Service and the free upgrade from Windows 7 and Windows 8.x for a year. You can see where this is headed.
But I have another idea. Perhaps this is intended to lead into their not-yet-disclosed enterprise licensing arrangement for Windows 10 (and related services)? Despite its consumer sound, Office 365 seems to have a fairly large adoption rate with business and education customers. As an example, which is not statistically relevant but is still interesting, the local public school board where I live has licensed a non-commercial, 5-PC license for every staff and student in their organization. This concept has a lot of potential for those customers.
If, of course, they give us a per-device and system builder license option, too.

After the great experience Phoronix had setting up the X1 Carbon with both Fedora and Ubuntu, they purchased a new Broadwell based NUC to experiment with. This model uses the Core i3 5010U with an onboard 900MHz HD Graphics 5500, support for 2 DIMMs of up to 64GB of DDR3-1866, an M.2 SSD card and a 2.5" HDD or SSD. Intel has stated that Ubuntu, Linux Mint, Fedora, and openSUSE will all be compatible so Phoronix has a bit of testing ahead of them. There are no benchmarks as of yet but you can see their teardown of this new NUC here.
"With wrapping up my Core i7 5600U Broadwell Linux tests using the new ThinkPad X1 Carbon in the next few days, fortunately the Intel BOXNUC5I3RYH just arrived as the first available NUC Kit shipping with a Broadwell processor. The NUC5i3RYH features a Broadwell Core i3 processor, HD Graphics 5500, and support for a M.2 SSD card and 2.5-inch HDD/SSD."

When the Razer Blade launched, it took a classy design and filled it with high-end gaming components. Its competitors in the gaming space were often desktop replacements, which were powerful but not comfortable, every-day laptops. The Blade also came with a $2800 (at the time) price-tag, and that stunted a lot of reviews. It has been refreshed a few times since then, including today.
The New Razer Blade QHD+ has a 14-inch 3200x1800 display, with multi-touch and an LED backlight. The panel is IGZO, which is a competitor to IPS for screens with a high number of pixels per inch (such as the 4K PQ321Q from ASUS). This is housed in a milled aluminum chassis that is about 7/10th of an inch thick.
Its power brick is rated at 150W, which is surprisingly high for a laptop. I am wondering how much of that electricity is headroom for fast-charging (versus higher performance when not on battery). Most power adapters for common laptops that I've seen are between 60W and 95W. In a small, yet meticulously designed chassis, I would have to assume that thermal headroom of either the heatsinks or the components themselves would be the limiting factor.
On the topic of specifications, they are expectedly high-end.
The GPU was upgraded to the GeForce GTX 970M with 3GB of VRAM (up from a 3GB 870M) and the CPU is now a Core i7-4720HQ (up from a Core i7-4702HQ). The system memory also got doubled, to 16GB (up from 8GB). It also has 3 USB 3.0 ports, HDMI 1.4a out, 802.11a/b/g/n/ac, Bluetooth 4.0, and (of course) a high-end, backlit keyboard. Razer offers a choice in M.2 SSD capacity: 128GB for $2199.99, 256GB for $2399.99, or 512GB for $2699.99. This is kind-of expensive for solid state memory, $1.56/GB for the jump to 256GB and $1.17/GB to go from there to 512GB.
The New Razer Blade Gaming Laptop is available now at Razerzone.com in the US, Canada, Singapore, and Hong Kong. It will arrive at Microsoft Stores in the USA on February 16th. China, Australia, New Zealand, Malaysia, UAE, Japan, Korea, Taiwan, and Russia can purchase it on Razerzone.com in March. Prices start (as stated above) at $2199.99.
