Richard Huddy Discusses FreeSync Availability Timeframes

Subject: General Tech, Displays | August 14, 2014 - 04:59 PM |
Tagged: amd, freesync, g-sync, Siggraph, siggraph 2014

At SIGGRAPH, Richard Huddy of AMD announced the release windows of FreeSync, their adaptive refresh rate technology, to The Tech Report. Compatible monitors will begin sampling "as early as" September. Actual products are expected to ship to consumers in early 2015. Apparently, more than one display vendor is working on support, although names and vendor-specific release windows are unannounced.

As for cost of implementation, Richard Huddy believes that the added cost should be no more than $10-20 USD (to the manufacturer). Of course, the final price to end-users cannot be derived from this - that depends on how quickly the display vendor expects to sell product, profit margins, their willingness to push new technology, competition, and so forth.

If you want to take full advantage of FreeSync, you will need a compatible GPU (look for "gaming" support in AMD's official FreeSync compatibility list). All future AMD GPUs are expected to support the technology.

Falcon Northwest Tiki-Z Special Edition Crams Titan Z And Liquid Cooled i7-4790K CPU Into A Stylish Micro Tower

Subject: General Tech, Systems | August 16, 2014 - 01:40 AM |
Tagged: titan z, tiki-z, gtx titan z, gk110, falcon northwest, dual gpu

The Tiki-Z Special Edition is the latest custom PC from boutique vendor Falcon Northwest. This high-end enthusiast system, which starts at $5,614 manages to pack a dual GPU graphics card, liquid cooled CPU, 600W power supply, and up to 6TB of storage into a stylish micro tower that measures a mere 4” wide and 13” tall.

Falcon Northwest has taken the original Tiki chassis and made several notable tweaks to accommodate NVIDIA’s latest dual GPU card: the GeForce GTX TITAN Z which we reviewed here. The case has a custom (partial) side window that shows off the graphics card. This window can be green glass or smoke tinted acrylic with customizable laser cut venting. A ducted intake feeds cool air to the graphics card and vents at the rear and front of the case exhaust hot air. The exterior of the case can be painted in any single color of automobile paint for free or with a fully customized paint scheme with artwork at an additional cost.

In addition to the Titan Z with its 5,760 CUDA cores, 12GB of memory, and 8.1 TFLOPS of peak compute power, Falcon Northwest has packed a modular small form factor 600W PSU from SilverStone, an ASUS Z97I Plus motherboard, Intel Core i7-4790K “Devil’s Canyon” CPU with liquid cooler, up to 16GB of DDR3 1866MHz memory from G.Skill, and up to 6TB of storage (two 1TB SSDs and one 4TB Western Digital Green hard drive). The i7-4970K comes stock clocked at 4GHz (4.4GHz max turbo), but can be overclocked by Falcon Northwest upon request.

Needless to say, that is a lot of hardware to cram into a PC that can easily sit next to your monitor at your desk or in your living room!

The engineering, artwork, and support of this high end system all come at a price, however. The new Titan Z powered boutique PC starts at $5,614 USD and is available now from Falcon Northwest. To sweeten the deal, for a limited time Falcon Northwest is including a free ASUS PB287Q 4K monitor (3820x2160, 60Hz, 1ms response time, see more specification in our review) with each Tiki-Z purchase.

This system is an impressive feat of engineering and it certainly looks sharp with the artwork, custom side panel, and compact form factor. My only concern from a usability standpoint would be noise from the cooling systems for the GPU, CPU radiator, and PSU. One also has to consider that the Titan Z graphics card by itself is priced at $3,000 which puts the Tiki Z pricing back into the somewhat sane world of boutique PC pricing (heh at about $2,600 for the system minus the GPU). No question, this is not going to be a system for everyone and will even be a niche product within the niche market of those enthusiasts interested in pre-built gaming systems. Even so, if noise levels can be held in check it will make for one powerful little gaming box!

Intel and Microsoft Show DirectX 12 Demo and Benchmark

Subject: General Tech, Graphics Cards, Processors, Mobile, Shows and Expos | August 13, 2014 - 09:55 PM |
Tagged: siggraph 2014, Siggraph, microsoft, Intel, DirectX 12, directx 11, DirectX

Along with GDC Europe and Gamescom, Siggraph 2014 is going on in Vancouver, BC. At it, Intel had a DirectX 12 demo at their booth. This scene, containing 50,000 asteroids, each in its own draw call, was developed on both Direct3D 11 and Direct3D 12 code paths and could apparently be switched while the demo is running. Intel claims to have measured both power as well as frame rate.

intel-dx12-LockedFPS.png

Variable power to hit a desired frame rate, DX11 and DX12.

The test system is a Surface Pro 3 with an Intel HD 4400 GPU. Doing a bit of digging, this would make it the i5-based Surface Pro 3. Removing another shovel-load of mystery, this would be the Intel Core i5-4300U with two cores, four threads, 1.9 GHz base clock, up-to 2.9 GHz turbo clock, 3MB of cache, and (of course) based on the Haswell architecture.

While not top-of-the-line, it is also not bottom-of-the-barrel. It is a respectable CPU.

Intel's demo on this processor shows a significant power reduction in the CPU, and even a slight decrease in GPU power, for the same target frame rate. If power was not throttled, Intel's demo goes from 19 FPS all the way up to a playable 33 FPS.

Intel will discuss more during a video interview, tomorrow (Thursday) at 5pm EDT.

intel-dx12-unlockedFPS-1.jpg

Maximum power in DirectX 11 mode.

For my contribution to the story, I would like to address the first comment on the MSDN article. It claims that this is just an "ideal scenario" of a scene that is bottlenecked by draw calls. The thing is: that is the point. Sure, a game developer could optimize the scene to (maybe) instance objects together, and so forth, but that is unnecessary work. Why should programmers, or worse, artists, need to spend so much of their time developing art so that it could be batch together into fewer, bigger commands? Would it not be much easier, and all-around better, if the content could be developed as it most naturally comes together?

That, of course, depends on how much performance improvement we will see from DirectX 12, compared to theoretical max efficiency. If pushing two workloads through a DX12 GPU takes about the same time as pushing one, double-sized workload, then it allows developers to, literally, perform whatever solution is most direct.

intel-dx12-unlockedFPS-2.jpg

Maximum power when switching to DirectX 12 mode.

If, on the other hand, pushing two workloads is 1000x slower than pushing a single, double-sized one, but DirectX 11 was 10,000x slower, then it could be less relevant because developers will still need to do their tricks in those situations. The closer it gets, the fewer occasions that strict optimization is necessary.

If there are any DirectX 11 game developers, artists, and producers out there, we would like to hear from you. How much would a (let's say) 90% reduction in draw call latency (which is around what Mantle claims) give you, in terms of fewer required optimizations? Can you afford to solve problems "the naive way" now? Some of the time? Most of the time? Would it still be worth it to do things like object instancing and fewer, larger materials and shaders? How often?

Khronos Announces "Next" OpenGL & Releases OpenGL 4.5

Subject: General Tech, Graphics Cards, Shows and Expos | August 15, 2014 - 08:33 PM |
Tagged: siggraph 2014, Siggraph, OpenGL Next, opengl 4.5, opengl, nvidia, Mantle, Khronos, Intel, DirectX 12, amd

Let's be clear: there are two stories here. The first is the release of OpenGL 4.5 and the second is the announcement of the "Next Generation OpenGL Initiative". They both occur on the same press release, but they are two, different statements.

OpenGL 4.5 Released

OpenGL 4.5 expands the core specification with a few extensions. Compatible hardware, with OpenGL 4.5 drivers, will be guaranteed to support these. This includes features like direct_state_access, which allows accessing objects in a context without binding to it, and support of OpenGL ES3.1 features that are traditionally missing from OpenGL 4, which allows easier porting of OpenGL ES3.1 applications to OpenGL.

opengl_logo.jpg

It also adds a few new extensions as an option:

ARB_pipeline_statistics_query lets a developer ask the GPU what it has been doing. This could be useful for "profiling" an application (list completed work to identify optimization points).

ARB_sparse_buffer allows developers to perform calculations on pieces of generic buffers, without loading it all into memory. This is similar to ARB_sparse_textures... except that those are for textures. Buffers are useful for things like vertex data (and so forth).

ARB_transform_feedback_overflow_query is apparently designed to let developers choose whether or not to draw objects based on whether the buffer is overflowed. I might be wrong, but it seems like this would be useful for deciding whether or not to draw objects generated by geometry shaders.

KHR_blend_equation_advanced allows new blending equations between objects. If you use Photoshop, this would be "multiply", "screen", "darken", "lighten", "difference", and so forth. On NVIDIA's side, this will be directly supported on Maxwell and Tegra K1 (and later). Fermi and Kepler will support the functionality, but the driver will perform the calculations with shaders. AMD has yet to comment, as far as I can tell.

nvidia-opengl-debugger.jpg

Image from NVIDIA GTC Presentation

If you are a developer, NVIDIA has launched 340.65 (340.23.01 for Linux) beta drivers for developers. If you are not looking to create OpenGL 4.5 applications, do not get this driver. You really should not have any use for it, at all.

Next Generation OpenGL Initiative Announced

The Khronos Group has also announced "a call for participation" to outline a new specification for graphics and compute. They want it to allow developers explicit control over CPU and GPU tasks, be multithreaded, have minimal overhead, have a common shader language, and "rigorous conformance testing". This sounds a lot like the design goals of Mantle (and what we know of DirectX 12).

amd-mantle-queues.jpg

And really, from what I hear and understand, that is what OpenGL needs at this point. Graphics cards look nothing like they did a decade ago (or over two decades ago). They each have very similar interfaces and data structures, even if their fundamental architectures vary greatly. If we can draw a line in the sand, legacy APIs can be supported but not optimized heavily by the drivers. After a short time, available performance for legacy applications would be so high that it wouldn't matter, as long as they continue to run.

Add to it, next-generation drivers should be significantly easier to develop, considering the reduced error checking (and other responsibilities). As I said on Intel's DirectX 12 story, it is still unclear whether it will lead to enough performance increase to make most optimizations, such as those which increase workload or developer effort in exchange for queuing fewer GPU commands, unnecessary. We will need to wait for game developers to use it for a bit before we know.

ASUS RT-AC87U Is First Wave 2 802.11ac Router Supporting MU-MIMO Technology

Subject: Networking | August 14, 2014 - 11:47 PM |
Tagged: wireless router, wave 2, rt-ac87u, rt-ac87r, qsr1000, mu-mimo, ASUS ROG, asus, 802.11ac

ASUS recently launched the RT-AC87U which is the first "wave 2" 802.11ac wireless router to support multi user MIMO (MU-MIMO) technology. Although the initial launch happened at the end of last month, the RT-AC87U and RT-AC87R (a variant exclusive to Best Buy) will finally be avaiable for purchase starting August 26th for around $279.99.

The RT-AC87U is a monster matte black router with four large external antennas and sleek fighter jet angles. I/O is mostly clustered on the rear of the router and includes four Gigabit Ethernet LAN ports, one GbE WAN port, and one USB 2.0 port. In addition to the rear I/O, ASUS has positioned a USB 3.0 port on the front of the router (specifically the right corner of the front panel hidden behind a removeable rubber port cover).

ASUS RT-AC87 First Wave 2 Wireless AC Router With MU-MIMO.jpg

On the wireless front, the RT-AC87U and RT-AC87R supports the latest 802.11ac and newer 256QAM (600Mbps) 802.11n specification as well as legacy 802.11g/b/a Wi-Fi networks. The router supports simultaneous dual band operation, which results in maximum throughput of 1.73 Gbps on the 5GHz 802.11ac band (4 x 433 Mbps streams) and 600 Mbps on the 2.4GHz 802.11n band.

The new and interesting bit about the RT-AC87 is the MU-MIMO support. MU-MIMO, which stands for Multi-User Multple Input Multiple Output, is the evolution of MIMO technology which debuted with wireless N routers. The ASUS router is able to use multiple anntennas to communicate with a client device to increase bandwidth. Beamforming is used to focus the signal in the direction of the client to get better range and a stronger signal for that specific client. MU-MIMO builds on this technology by allowing the router to track, beamform, and employ multiple transmit and recieve antennas to talk to multiple clients simultaneously. Previously, routers were limited to communicating with a single client at a time (see the diagram below for an example).

SU-MIMO-compared-to-MU-MIMO.png

Multi-User MIMO will benefit those users that choose to connect the majority of their networked devices via Wi-Fi. However, the technology will be especially noticeable in areas flooded with various Wi-Fi networks such as apartments. According to Matthew Gast of Aerohive Networks, MU-MIMO will allow all wireless clients to get an acceptable data rate in crowded wireless areas at the expense of being able to deliver the highest data rate to a single client device. Especially when competing Wi-Fi networks are involved and fighting for channels, MU-MIMO will shine at keeping devices connected and talking to the access point. 

ASUS has chosen the Quantenna QSR100 chipset to handle the 802.11ac duties while a Broadcom BCM4709 chipset handles the 256QAM wireless N bands. Additionally, the RT-AC87 routers have 128MB of flash memory and 256MB of DDR3 RAM. According to ASUS, the router draws slightly over 45W.

On the software side of things, ASUS has chosen its own ASUSWRT firmware which includes parental controls, Time Machine backup support, VPN support, security software from TrendMicro (AiProtection), and AiCloud 2.0. USB support includes storage sharing as well as 3G/4G cellular modem internet connectivity.

In all, the ASUS RT-AC87U looks to be new home router champion packing quite a bit of hardware and leading the charge of Wave 2 802.11ac wireless routers. This all comes at a cost, however. The RT-AC87U and RT-AC87R will be available on August 26 with a MSRP of $269.99 and e-tail prices currently around $279.99.

An odd Q2 for tablets and PCs

Tagged: jon peddie, gpu market share, q2 2014

Jon Peddie Research's latest Market Watch adds even more ironic humour to the media's continuing proclamations of the impending doom of the PC industry.  This quarter saw tablet sales decline while overall PCs were up and that was without any major releases to drive purchasers to adopt new technology.  While JPR does touch on the overall industry this report is focused on the sale of GPUs and APUs and happens to contain some great news for AMD.  They saw their overall share of the market increase by 11% from last quarter and by just over a percent of the entire market.  Intel saw a small rise in share though it does still hold the majority of the market as PCs with no discrete GPU are more likely to contain Intel's chips than AMDs.  That leaves NVIDIA who are still banking solely on discrete GPUs and saw over an 8% decline from last quarter and a decline of almost two percent in the total market.  Check out the other graphs in JPR's overview right here.

"The big drop in graphics shipments in Q1 has been partially offset by a small rise this quarter. Shipments were up 3.2% quarter-to-quarter, and down 4.5% compared to the same quarter last year."

Prying OpenGL to slip a little Mantle inside

Tagged: amd, Mantle, opengl, OpenGL Next

Along with his announcements about FreeSync, Richard Huddy also discussed OpenGL Next and its relationship with Mantle and the role it played in DirectX 12's development.  AMD has given Chronos Group, the developers of OpenGL, complete access to Mantle to help them integrate it into future versions of the API starting with OpenGL Next.  He also discussed the advantages of Mantle over DirectX, citing AMD's ability to update it much more frequently than Intel has done with DX.  With over 75 developers working on titles that take advantage of Mantle the interest is definitely there but it is uncertain if devs will actually benefit from an API which updates at a pace faster than a game can be developed.  Read on at The Tech Report.

Meet Tonga, soon to be your new Radeon

Tagged: tonga, radeon, FirePro W7100, amd

A little secret popped out with the release of AMD's FirePro W7100, a new family of GPU that goes by the name of Tonga, which is very likely to replace the aging Tahiti chip that has been used since the HD 7900 series.  The stats that The Tech Report saw show interesting changes from Tahiti including a reduction of the memory interface to 256-bit which is in line with NVIDIA's current offerings.  The number of stream processors might be reduced to 1792 from 2048 but that is based on the W7100 and it the GPUs may be released with the full 32 GCN compute units.  Many other features have seen increases, the number of Asynchronous Compute Engines goes from 2 to 8, the number of rasterized triangles per clock doubles to 4 and it adds support for the new TrueAudio DSP and CrossFire XDMA.

IMG0045305.jpg

"The bottom line is that Tonga joins the Hawaii (Radeon R9 290X) and Bonaire (R7 260X) chips as the only members of AMD' s GCN 1.1 series of graphics processors. Tonga looks to be a mid-sized GPU and is expected to supplant the venerable Tahiti chip used in everything from the original Radeon HD 7970 to the current Radeon R9 280."

It's so cool, and so tiny

Corsair continues to march down the path of making a PC case for just about every user imaginable. At Computex this past June, Corsair announced the Carbide Air 240 case, which is a smaller version of the very popular (and well reviewed) Carbide Air 540. These unique cases include two separate compartments: one for the motherboard, CPU, and graphics card and another for the power supply, storage, and miscellaneous cable clutter. The result is a sleek cube-shaped form factor that is easy to build inside.

Available in both black and white (with UV resistant paint), the $89/99 case fits both Mini-ITX and Micro-ATX motherboards allowing quite a bit of component flexibility.

IMG_9492.JPG

A quick look at the front of the case shows the cube-like shape that both the Air 540 and Air 240 share, a form factor resulting from the dual-compartment design. The Corsair logo in the center can actually be rotated depending on the orientation of the case which itself can be rotated to allow the windowed case door to be the top of the case rather than the side.

Keep reading our overview of the Corsair Carbide Air 240 with plenty more photos and descriptions!!

As far as factory overclocks go, the 1080MHz core and 5.64GHz RAM on the new Sapphire Vapor-X 290X is impressive and takes the prize for the highest factory overclock on this card [H]ard|OCP has seen yet.  That didn't stop them from pushing it to 1180MHz and 5.9GHz after a little work which is even more impressive.  At both the factory and manual overclocks the card handily beat the reference model and the manually overclocked benchmarks could meet or beat the overclocked MSI GTX 780 Ti GAMING 3G OC card.  The speed is not the only good feature, Intelligent Fan Control keeps two of the three fans from spinning when the GPU is under 60C which vastly reduces the noise produced by this card.  It is currently selling for $646, lower than the $710 that the GeForce is currently selling for as well.

Razer BlackWidow Ultimate Chroma Announced

Tagged: razer, mechanical keyboard

Earlier in the year, we reported on Corsair's exclusivity over Cherry MX RGB-based mechanical keyboards. The thing is, Razer develops their own switches and is not reliant on ZF Electronics (Cherry Corporation). The Razer BlackWidow Ultimate Chroma mechanical keyboard uses their own switches, not Cherry's, and is not subject to Corsair's exclusivity. The keyboard can be ordered now for $179.99 USD and will be available in September.

razer-blackwidow-ultimate-chroma-front.png

I contacted Razer and asked them about their technology. They could not provide any direct comparison between their design and the Cherry MX RGB, but they were able to add a few details to their offering. The BlackWidow Ultimate Chroma was designed with its LEDs positioned away from moving parts and lined up with the keycap imprint. The LEDs are pointed upward for brightness.

Razer will be providing developers with Chroma SDK, allowing games and applications to control the Chroma-enabled device lighting to assist or immerse their users. I say "Chroma-enabled device" rather than "Chroma keyboards", because they already have plans for mice and headsets with the same technology. At the very least, they expect that users will appreciate coordinated colors across their gaming peripherals.

The Razer BlackWidow Ultimate Chroma is available to order, for $179.99 USD ($199.99 CDN), and ships in September. A Chroma-enabled mouse, based on the DeathAdder design, and a Chroma-enabled headset, based on the Kraken model, are announced but do not yet have pricing or availability information.

Introduction, Specifications and Packaging

Introduction:

OCZ is on what I would consider to be an upswing now that it exists under the relative safety of its parent company, Toshiba. Shortly after they were acquired, OCZ cut a bunch of unnecessary and/or redundant SKUs from their inventory and simultaneously began the transition of all of their product lines to exclusively use Toshiba branded flash. It only makes sense, given that flash is now available in-house - a luxury OCZ had wanted to have for quite some time. The changeover so far has refreshed the Vector 150, Vertex 460, and most recently the RevoDrive 350. Today OCZ has made another change, but instead of refreshing an old product, they are introducing a new one:

DSC04573.JPG

Behold the ARC 100!

To those wondering why OCZ needs another model SSD, and where that model will fall in their lineup, here's everything you need to see:

comparison.png

...so we have a slightly de-rated SSD, with the same Indilinx Barefoot controller, and the same Toshiba 19nm flash, but with a *significantly* reduced price. I wouldn't sweat the 20GB/day rating, as the vast majority of users will average far less than that daily when that usage is spread over a multi-year period. Even heavy gamers that blow through 100+GB of writes on an initial system and game install will still average far less than that over the subsequent months and years. Here is a look at the complete OCZ product spectrum, including their business and PCIe offerings:

In our prior (and this) review, we've covered the whole bottom row. While we have reviewed the Z-Drive 4500 / XL's predecessor (the Z-Drive R4), The 4500 is not yet on finalized firmware. 

OK, so they've got my attention with this price thing, so lets see how well the ARC performs given its lower cost:

Corsair Vengeance LPX and Dominator Platinum DDR4 Memory

Subject: Memory | August 15, 2014 - 12:24 PM |
Tagged: ddr4, corsair, Vengeance LPX, Dominator Platinum

FREMONT, California — August 14, 2014 — Corsair, a leader in high-performance PC hardware, today announced the availability of Corsair Vengeance LPX and Dominator Platinum lines of high-speed DDR4 computer memory. This new generation of memory ushers in a new age of ultrafast computing with optimizations such as increased DRAM bandwidth, higher bus frequencies, lower power usage, and higher reliability.

Corsair Vengeance LPX and Dominator Platinum DDR4 memory kits are validated with motherboard partners (ASUS, ASRock, EVGA, Gigabyte, and MSI) and use the new XMP 2.0 profile to deliver easy, reliable overclocking performance with the upcoming next-generation Intel® X99 platforms and Intel® Core™ i7 processors (codenamed Haswell-E). The Vengeance LPX and Dominator Platinum memory kits are supplied with a limited lifetime warranty.

unnamed.png

Vengeance LPX

Vengeance LPX memory is a new Corsair memory line designed for high-performance overclocking with a low-profile heatspreader is made of pure aluminum for faster heat dissipation and the eight-layer PCB helps manage heat and provides superior overclocking headroom. The memory kits are available in black, red, white, or blue so that enthusiasts, gamers, and modders can add a touch style to match the color scheme of their PC.

unnamed2.png

Dominator Platinum

Like the DDR3 memory versions, the new Dominator Platinum DDR4 memory kits have a striking industrial design for good looks, patented DHX technology for cooler operation, user-swappable colored “light pipes” for customizable downwash lighting, and Corsair Link compatibility for real-time temperature monitoring. Dominator Platinum memory is built with hand-screened ICs, undergoes rigorous performance testing, and incorporates state-of-the-art cooling for reliable performance in demanding environments.

Vengeance LPX and Dominator Platinum DDR4 Specifications

  • Unbuffered DDR4 SDRAM in 288-pin DIMM
  • Capacities at launch: 8GB (2x4GB), 16GB (4x4GB), 32GB (4x8GB) and 64GB (8x8GB)
  • Speeds at launch: 2666MHz, 2800MHz, and 3000MHz
  • Intel XMP 2.0 (Extreme Memory Profile) support

About DDR4
DDR4 is faster. Even at the baseline speed of DDR4 delivers twice the bandwidth with 2133 MT/s (million transfers per second) compared with the base DDR3 1600 MT/s. With optimizations games and applications have the potential to load faster and run more smoothly.

DDR4 uses a lot less power and runs cooler.
With each new generation of CPU and GPU architecture, system power consumption and heat generation become more and more important. DDR4 modules operate at an ultra-low standard 1.2 volts compared to the 1.5 and 1.65 volts of DDR3 memory, allowing DDR4 memory to consume significantly less power and generate less heat.

DDR4 memory modules can get bigger.
DDR3 is limited to 8GB modules for a maximum of 32GB on standard four-socket motherboards. DDR4 will have the ability to enable 16GB per module by 2015. A motherboard with eight memory slots will be upgradeable to an amazing 128GB or DDR4 memory.

Pricing, Availability, and Warranty
Corsair Vengeance LPX Series and Dominator Platinum DDR4 memory kits will be available at the end of August from Corsair's worldwide network of authorized distributors and resellers. The Vengeance LPX and Dominator Platinum memory kits are supplied with a limited lifetime warranty and are backed up by Corsair's customer service and technical support.

The third incarnation of Microsoft's Pro Tablet Surfaces

Subject: Mobile | August 15, 2014 - 02:22 PM |
Tagged: Surface Pro 3, microsoft

With a 12" 2160x1440 resolution screen, a 4th generation Core i3, i5 or i7 and a full version of Win 8.1 the new Surface Pro 3 is the best tablet offered by Microsoft so far.  Overall it is thinner but 1.5" larger than the Pro 3 with better resolution with a battery that should last about 8 hours while you are working, slightly longer when just browsing.  The Surface Pen is a nice addition to the dock and stand we have become familiar with.  Overall The Inquirer was fairly impressed with Microsoft's new offering, apart from the pricing which is rather prohibitive even before accessorizing.

"THE SURFACE PRO 3 tablet brings some of the biggest and most welcome changes seen in the Surface tablet line yet, with a bigger and better 12in HD screen, a much thinner case and an improved keyboard and kickstand, meaning its never lived more up to its motto of "the tablet that can replace your laptop."

Also, Corsair's Cherry MX RGB Launch Date Changed

Tagged: corsair, mechanical keyboard, cherry mx rgb

So I actually did not see this until after I published the Razer story. Just a few hours ago, Corsair posted an announcement to their Facebook page that claimed a "cbange" in launch date for their Cherry MX RGB-based keyboards. I actually forgot that the K70 RGB Red was supposed to be out already, with availability listed as "late July" (the rest were scheduled to arrive in "late August"). Corsair does not yet have a new date, but will comment "in a few weeks".

Got to say, that does look nice.

While, again, no further details are given, it sounds like a technical hurdle is holding back the launch. Corsair claims that they want the product to live up to expectations. This, of course, chips further at the company's exclusivity window and could put them in direct competition with Razer's custom design, and may even be available second, almost in spite of the exclusivity arrangement.

Unreal Tournament's Training Day, get in on the Pre-Pre-Alpha right now!

Subject: General Tech | August 13, 2014 - 02:02 PM |
Tagged: Unreal Tournament, gaming, Alpha

Feel like (Pre-Pre-)Alpha testing Unreal Tournament without forking money over for early access?  No problems thanks to Epic and Unreal Forums member ‘raxxy’ who is compiling and updating the (pre)Alpha version of the next Unreal Tournament.  Sure there may not be many textures but there is a Flak Cannon so what could you possible have to complain about?  There are frequent updates and a major part of participating is to give feedback to the devs so please be sure to check into the #beyondunreal IRC channel to get tips and offer feedback.  Rock, Paper, SHOTGUN reports that the severs are massively packed now so you may not be able to immediately join in but it is worth trying.

raxxy would like you to understand "These are PRE-ALPHA Prototype Builds. Seriously. Super early testing. So early it's technically not even pre alpha, it's debug code!"

You can be guaranteed that the Fragging Frogs will be taking advantage of this, as well as revisiting the much beloved UT2K4 so if you haven't joined up yet ... what are you waiting for?

Check out Fatal1ty playing if you can't get on

"Want to play the new Unreal Tournament for free, right this very second? Cor blimey and OMG you totes can! Hero of the people ‘raxxy’ on the Unreal Forums is compiling Epic’s builds and releasing them as small, playable packages that anyone can run, with multiple updates per week. The maps are untextured, the weapons unbalanced, and things change rapidly as everything’s still “pre-alpha” but it’s playable and – more importantly – fun."
