Gaming mice have wires as it reduces input lag that would otherwise be the death of you while gaming.  Unfortunately for some this means they cannot sit on the couch streaming YouTube to their TVs since the wire on their mouse just isn't long enough.  SteelSeries claims to have overcome the technical problems of gaming wirelessly with their SteelSeries Sensei.  The software is definitely aimed at gamers, with an impressive array of settings to tweak and an impressive macro editor but that is not enough to solve the performance issues.  Believe it or not when TechGage compared it to a wired mouse they could not detect any difference whatsoever.  I would still recommend wearing pants while frying bacon regardless of your final mouse choice.

"Want a high-performance wireless gaming mouse that doesn’t have its battery-life measured in seconds? Well, SteelSeries has released its renowned Sensei into the wild, free to run and frolic in grassy meadows, without the need of being tethered to unsightly cables. Does the result live up to our high expectations? There’s only one way to find out."

Gigabyte's New Essence Chassis Enables Fanless Mini PCs

Subject: Cases and Cooling | August 17, 2014 - 01:18 AM |
Tagged: SFF, mini ITX, gigabyte, fanless, essence, Bay Trail

Gigabyte recently rolled out a new small form factor case called the Essence for DIY PCs. The chassis measures 300mm x 234mm x 74mm (~11.8" x 9.2" x 2.9"), comes bundled with a 120W PSU, and will happily hold a Mini ITX motherboard and laptop-sized hard drive. Large mesh vents on the side panels allow for plenty of airflow and ventilation to run a fanless system.

The Essence case uses a SECC frame along with ABS plastic. A rectangular base, which hosts the front IO ports, holds the machine vertically and at a slight backwards tilt. The DC power components are mounted to the bottom of the motherboard tray and are driven by a 120W external power supply (Similar to the type of setup the Xbox 360 uses). The red removable motherboard tray (accessible via the right side panel) allows you to screw in a Mini ITX motherboard and a single 2.5" SSD or HDD up to 9.5mm thick.

The front IO includes two USB 2.0 ports, one headphone output, and one microphone jack. Aesthetically speaking, the Essence looks nice with its red faceplate, silver power button, and black mesh side panels with embossed shapes. It is small enough that it could easily sit next to a monitor and act as a low power desktop or next to the TV as a home theater PC. So long as you do not mind it not fitting into an AV rack/stack, this case could be used along with a cheap SSD and fanless Bay Trail or Kabini-based system for a silent media box or streaming client for Steam games.

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.

Falcon Northwest Tiki-Z Micro Tower.jpg

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!

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.

The third incarnation of Microsoft's Pro Tablet Surfaces

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.

surface-pro-3-review-tablet-540x334.jpg

"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."

Prying OpenGL to slip a little Mantle inside

Subject: General Tech | August 15, 2014 - 01:09 PM |
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.

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.

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.

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.

amd-freesync1.jpg

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.

That Linux thing that nobody uses

For many Linux is a mysterious thing that is either dead or about to die because no one uses it.  Linux.com has put together an overview of what Linux is and where to find it being used.  Much of what they describe in the beginning applies to all operating systems as they share similar features, it is only in the details that they differ.  If you have only thought about Linux as that OS that you can't game on then it is worth taking a look through the descriptions of the distributions and why people choose to use Linux.  You may never build a box which runs Linux but if you are considering buying a Steambox when they arrive on the market you will find yourself using a type of Linux and having a basic understanding of the parts of the OS for troubleshooting and optimization.   If you already use Linux then fire up Steam and take a break.

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.

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.

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.

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?

To boldy go where no 290X has gone before?

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.

"We take a look at the SAPPHIRE Vapor-X R9 290X TRI-X OC video card which has the highest factory overclock we've ever encountered on any AMD R9 290X video card. This video card is feature rich and very fast. We'll overclock it to the highest GPU clocks we've seen yet on R9 290X and compare it to the competition."

The downwards Arc of flash prices; OCZ releases an SSD at $0.50/GB

Before even looking at the performance the real selling point of the new OCZ ARC 100 is the MSRP, the 240GB and 480GB models are slated to be released at $0.50/GB and will likely follow the usual trend of SSD prices and drop from there.  The drives use the Barefoot 3 controller, this one clocked slightly lower than the Vertex 460 but still capable of accelerating encryption.  Once The Tech Report set the drive up in their test bed the performance was almost on par with the Vertex 460 and other mid to high end SSDs, especially in comparison to the Crucial MX100.

Make sure to read Al's review as well, not just for the performance numbers but also an explanation of OCZ's warranty on this drive.

"OCZ's latest value SSD is priced at just $0.50 per gig, but it hangs with mid-range and even high-end drives in real-world and demanding workloads. It's also backed by an upgraded warranty and some impressive internal reliability data provided by OCZ. We take a closer look:"

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."
