Update (June 22-2013, 4:43pm EDT): I was contacted by Noctua about the TDP ratings... quoting from their email:
As for the question regarding the TDP rating of the original NH-D14, I'd like to stress that the cooler can *easily* handle any 130W CPU! Our D14 is renowned to be among the best performing heatsinks for overclocking on the market and and many users have pushed their CPUs well beyond 250W using this cooler.
Noctua apparently does not like including TDP values for their coolers because it varies heavily on the conditions (such as, of course, room and case temperature). It makes sense, of course, because then customers would go looking at reviews and see what overclocks were achieved with the system.
Yes, I know Computex is long over, but I missed something that I want to cover.
Noctua has been teasing active noise cancellation (ANC) for their CPU coolers for quite some time now; Tim published his brief thoughts, 13 months ago, on their press release leading up to Computex 2012. The prototype, this year, is a full unit rather than the fan from last year.
This design is a modified NH-D14 cooler with added technology from RotoSub AB to sample its own noise and destructively interfere. According to Noctua, this will be the first ANC cooling unit for a CPU. The plan, as their press release suggests, is to release a cooler with the model named "R-ANC" after its (R)otoSub (A)ctive (N)oise (C)ancellation (R-ANC) technology. To me, this seems like a confusing choice in name as it breaks away from their existing standard and limits choice in name for future models based on this technology. Personally, I would have preferred to see "NH-D14R" or "NH-D14ANC", but alas I am not a marketer.
Also, in the process of researching for this article, I have been unable to find a canonical TDP-rating for this device. I was not too surprised to have a difficult time finding it for this unreleased product, but TDP is even omitted from the established, albeit louder, default NH-D14. Some sources claim this cooler can support an Intel i7 Extreme processor, which typically requires a 130W thermal dissipation; other sources say you should be somewhat cautious with this cooler with CPUs >95W TDP; some even claim it is great for air-only overclocking. Rolling all of these sources together, assuming a kernel of truth in each, I would assume this cooler (and, by extension, its upcoming R-ANC variant) would be good for decent air-only overclocks until you reach the -E series.
But, grain of salt, have some.
No word of pricing, but Noctua believes they will have it available spring/summer of next year. For some reference, the default NH-D14 can be found for about $75-$100; expect the R-ANC to be slightly north of that.

Tagged: Ultra, geforce titan, computex
So long to Computex 2013, we barely knew thee. You poured stories all over our news feed for more than a whole week. What say you, another story for the... metaphorical road... between here... and... Taipei? Okay, so the metaphorical road is bumpy and unpaved, work with me.
It was substantially more difficult to decipher the name of a video card a number of years ago. Back then, products would be classified by their model numbers and often assigned a suffix like: "Ultra", "Pro", or "LE". These suffixes actually meant a lot, performing noticeably better (or maybe worse) than the suffix-less number and possibly even overlapping with other number-classes.
Just when they were gone long enough for us to miss them, the suffixes might make some measure of a return. On the show floor, Colorful exhibited the NVIDIA GeForce GTX Titan Ultra Edition. This card uses a standard slightly-disabled GK110-based GeForce GTX Titan GPU, with the usual 2688 CUDA cores, and 6GB of GDDR5. While the GK110 chip has potential for 2880 CUDA cores, NVIDIA has not released any product (not even Tesla or Quadro) with more than 2688 CUDA cores enabled. Colorful's Titan Ultra and the reference Titan are electrically identical; this "Ultra" version just adds a water block for a cooling system and defaults to some amount of a factory overclock.
But, this is not the first time we have heard of a Titan Ultra...
Back in April, ExtremeTech found a leak for two official products: the GTX Titan LE and the GTX Titan Ultra. While the LE would be slightly stripped down compared to the full GTX Titan, the GTX Titan Ultra would be NVIDIA's first release of a GK110 part without any CUDA cores disabled.
So if that rumor ends up being true, you could choose between Colorful's GTX Titan Ultra with its partially disabled GK110 based on the full GTX Titan design; or, you could choose the reference GTX Titan Ultra based on a full GK110 GPU unlike the partially disabled GK110 on the full GTX Titan.
If you are feeling nostalgic... that might actually be confusion... as this is why suffixes went away.

Following Intel's announcement of new Haswell sleep states, various power supply manufacturers have released compatibility lists detailing which PSUs are able to deliver the low load necessary to support the power sipping sleep states on the 12V rail (which has not been much of a concern until Haswell).
One such PSU manufacturer was Seasonic, who has quite a few Haswell-ready power supplies across several lineups including its Platinum, G, and M12II series, among others. Included in that compatibility list were two new power supplies that Seasonic is showing off at Computex this week: the Seasonic Platinum 1200 and Seasonic M12II Bronze Evo Edition.
SeaSonic Platinum 1200
The Platinum 1200 is a high-end modular power supply that is capable of powering beefy multi-GPU setups. It is 80+ Platinum rated and is up to 92% efficient at 50% load.
Sesonic M12II Bronze Evo Edition
The Seasonic M12II Bronze Evo Edition is an updated version on past models and includes two SKUs that come in at 750W and 850W. It is a fully modular unit with flat black cables and fan control tech. It is 80+ Bronze and Energy Star rated, and is compatible with Intel's 4th Generation Core processors.

Tagged: unreal engine 4, ue4, E3 13, E3, computex
We are bleeding through the overlap between Computex and E3 media windows; this news has a somewhat relevant fit for both. Unreal Engine 4 is coming and I expect we will see one or more demos and UE4-powered titles over the next week. In fact, I would be fairly shocked if we do not see the end of the Elemental Demo with the Xbox One E3 keynote. We may also potentially see Unreal Engine 4 running on mobile devices and maybe even HTML5 at some point throughout the tradeshow, either canonically through Epic or via a licensee product.
This morning, Epic opened the Unreal Engine 4 Integrated Partners Program (IPP). Of course they already have a couple of members, most of which were partners with Unreal Engine 3.
The founding IPP partners are:
Wwise from Audiokinetic
- Manages large databases of sound effects and voice-overs
- Manages subtitles and multiple dubbings of voice clips
Autodesk Gameware from Autodesk
- Contains multiple packages including Beast, Navigation, and Scaleform
- Scaleform is a Flash rendering engine for HUDs, menus, etc. developed using Flash Professional in 2D or 3D. It is what StarCraft II, Mass Effect, and Borderlands uses.
- Beast is a lighting toolkit for global illumination, radiosity, etc.
- Navigation is an AI solver, predominantly for pathfinding.
Simplygon from Donya Labs
- Reduces polygon count of models so they take up less processing resources especially as they get further away from the camera.
Enlighten from Geomerics
- Another Global Illumination solver, most popular usage being Battlefield 3.
SpeedTree for Games from IDV
- Makes a bunch of efficient trees so studios do not need to hire as many minimum wage peons.
Intel Threading Building Blocks (TBB) from Intel
- Helps developers manage C++ threading for multicore systems.
- Deals with memory management and scheduling tasks
morpheme from NaturalMotion
- Animation and physics software for designers to create animations
- Works with NVIDIA PhysX
euphoria from NaturalMotion
- Simulates animations based on driving conditions via the CPU, most popular usage being GTA IV.
PhysX and APEX from NVIDIA
- You probably know this one.
- GPU-based rigid body, soft body, fluid, and cloth solvers.
- Allows for destructible environments and other complex simulations.
Oculus Rift from Oculus VR
- You probably also know this one, especially if you keep up with our Video Perspectives.
- Head-mounted display with motion tracking for VR.
Bink Video from Rad Game Tools
- ... is not included! Just kidding, that stuff'll survive a nuclear apocalypse.
- Seriously, check in just about any DirectX or OpenGL game's credits if it includes pre-rendered video cutscenes or video-textures.
- I'll wait here.
- In all seriousness, Rad Game Tools has been licensed in over 15,500 titles. It's been a meme to some extent for game programmers. This should be no surprise.
Telemetry Performance Visualizer from Rad Game Tools
- Allows developers to see graphs of what their hardware is working on over time.
- Helps developers know what benefits the most from optimization.
RealD Developer Kit (RDK) from RealD
- Helps game developers create stereoscopic 3D games.
Umbra 3 from Umbra Software
- Determines what geometry can be seen by the player and what should be unloaded to increase performance.
- Sits between artists and programmers to the former does not need to think about optimization, and the latter does not need to claw their eyes out.
IncrediBuild-XGE from Xoreax
- Apparently farms out tasks to idle PCs on your network.
- I am not sure, but I think it is mostly useful for creating a pre-render farm at a game studio for light-baking and such.
We still have a little while until E3 and so we do not know how E3 will be, but I highly expect to see Unreal Engine 4 be a recurring theme over the next week. Keep coming back to PC Perspective, because you know we have a deep interest in where Epic is headed.

Intel had a host of new technologies to show off at Computex this year, starting of course with the Haswell processor launch. Hopefully you have read our review of the Core i7-4770K LGA1150 CPU already but thanks to some video sent our way, we have other interesting bits to share.
Below you will see Intel demonstrating four new products. First is the Acer Aspire S7 using a Haswell dual-core platform playing back 4K content. Next up is an Ivy Bridge tablet that is running completely fanless (passive) thus generating no noise at all while still offering impressive CPU and graphics performance. Intel then pulls a Lenovo K900 Android smartphone out of its pocket powered by the Clovertrail+ enabled Atom Z2580 SoC. Finally, we get a sneak peak at the next-generation of SoC designs with a look at a Silvermont-based Baytrail tablet running at 2560x1440.

Tagged: evga, minibox, mini-itx, gtx titan, gk110, gaming, computex, computex 2013
First shown off at CES 2013, the EVGA Minibox is a small form factor chassis for Mini-ITX systems that can accommodate large graphics cards. EVGA has managed to enable users to pack a lot of hardware into this tiny form factor chassis. As a demonstration of the case's capabilities, the company showed off the latest version using a full system build with Core i7-4770K and GTX TITAN interals at Computex this week in Taipei.
The Minibox chassis itself is a dark brushed metal case with two USB 3.0 ports on the front IO and space for a slot loading optical drive. The MiniBox chassis further features a motherboard tray that supports Mini-ITX boards, two 2.5" SATA hard drive bays – and best of all – enough room to install full size GPUs. In order to support lengthy graphics cards, EVGA is including a small form factor 500W power supply that is mounted on the floor of the case..
HEXUS reporters spot the EVGA Minibox at Computex 2013. Look how small it is!
There will be at least two SKUs of the Minibox, depending on whether you want to go with air or water cooling. According to Bit-Tech.net, the air cooled version will use two 92mm fans in the top of the case and one 80mm fan for the bottom-mounted PSU. The water cooled SKU will be slightly larger but have enough room for a water cooling radiator (likely 240mm). Beyond that, details are scarce, but the air cooled version is said to be available as soon as next month with water cooled options becoming available later this year.
The Minibox looks to be one of the better Mini-ITX cases out there (although the price is still unknown), and should be popular among enthusiasts wanting a small box that does not sacrifice gaming potential.

Tagged: computex, Windows 8.1, windows blue
Jensen Harris, member of the Windows User Experience (UX) team at Microsoft, performed a video walk-through of the new Windows interface. Of course, as I always say when discussing Windows 8, the real problems will arise with the Windows Store and certification requirements; interface problems annoy, censorship problems harm.
But, disclaimer aside, the interface of Windows 8.1 seems much more useable.
First and foremost is the Lock Screen. People enjoy digital photo frames and a locked tablet certainly looks more classy than any other that I have seen. It will collage photos together, stored locally and shared from a phone or Skydrive over wireless, with a thin font date and time. Combined with a decent resolution IPS display, that could be an interesting way to encourage users to leave their device on its charger. Not to mention, the frame would continually synchronize with Skydrive and thus receive new photos without end-user interaction; it is useful, for instance, for the family of an elderly person who wants to keep in touch but actively rejects technology.
The All Apps screen lists all applications installed on screen. This allows users to take a little weight off of the Start Screen and, instead of using it as a launcher, use the All Apps screen as a launcher and use the Start Screen as a nexus of important information. If you wish to use the Start Screen as a launcher, similar to pinned icons for Windows 7, you will have more choice in icon size to either fit more apps or give tiles with relevant information more space.
Screen splitting was pretty horrendous in Windows 8. An application could either be in full screen, be a sidebar app, or take up the room not taken by a sidebar app. If you have multiple monitors, bringing up the Start Screen would shuffle everything around pretty much ensuring that you do not have more than a couple of apps focused at any given time. Windows 8.1 allows you to split apps directly down the middle and, if you have a large display, allow you to fit three or four applications on screen at once.
Unfortunately, and I contacted Paul Thurrott last week to confirm I was up to date, there does not seem to be any multiple monitor enhancements in Windows 8.1. If you have want to punch through your second display because of applications from the Windows Store, keep using the desktop.
Or, if you wish to try it out for yourself, Windows 8.1 will be available for public preview on June 26th.

Tagged: computex, thunderbolt, Thunderbolt 2, Light Peak
We received Thunderbolt, on the PC at least, a year ago. While not yet ubiquitous, we will be receiving an update to the interface sooner than you would expect. The main advantages of Thunderbolt is the ridiculous bandwidth and ability to daisy-chain with displays. Thunderbolt 2 looks to advance both of those features.
Thunderbolt is based around a PCI Express signal for data and DisplayPort for video, both combined down a single cable. The cable, in fact, is compatible with Mini DisplayPort adapters and devices if used exclusively for video. The upgrade to Thunderbolt 2 advances the video standard to DisplayPort 1.2; as a result, Thunderbolt 2 devices will be capable of driving a 4K monitor (supposedly with sound) without requiring multiple cables to be connected.
In terms of strict bandwidth, Thunderbolt 2 will provide double the data rate of the original Thunderbolt. Instead of 10Gbps, new devices will be able to transfer at 20Gbps. This is especially useful for video content creators looking to manage, in real time, 4K or 120Hz data transferring between cameras and video gear. Struggling with large video capture bandwidth is something we know about...
As expected, there is not really any talk about specific prices yet (I would expect that depends on implementation) but you should look forward to it landing either really late this year or early next year. As for the original Thunderbolt? Well, the new standard is backwards compatible but there is concern whether new devices would be fairly crippled without the new standard.
Computex 2013: Gigabyte Shows Off GA-990FXA-UD7 AM3+ Motherboard That Hints At 5GHz AMD FX Processor

Gigabyte is showing off quite a few motherboards at Computex 2013. One of the most interesting motherboards on display is the GA-990FX-UD7 for AMD AM3+ desktop processors. This is a high-end motherboard for enthusiasts and is packed with features.
The GA-990FX-UD7 features an 8+2 power phase, AM3+ CPU socket, four DDR3 DIMM slots, six PCI-E 2.0 x16 (physical) slots, one legacy PCI slot, and eight SATA 3 6Gbps ports. It has a black and glossy orange color scheme with large finned heatsinks around the CPU socket and over the southbridge. The board uses a Realtek ALC889 chipset for onboard audio that supports Dolby Home Theater and has a 108dB SNR rating. Further, the GA-990FX-UD7 supports 4-way SLI or CrossFire, Gigabyte's UEFI DualBIOS, and 3X power which allows faster battery charging for supported USB-connected mobile devices.
The Gigabyte GA-990FX-UD7 at Computex 2013 as spotted by Sweclockers (Click for larger image).
Rear IO includes a single coaxial S/PDIF and six analog audio outputs, four USB 3.0 ports, two eSATA+USB combo ports, and a RJ45 LAN jack.
Interestingly, Gigabyte's Computex display mentions that the new AM3+ motherboard is compatible with AMD's 5GHz AM3+ processor, which lends credibility to previous rumors of a Piledriver-based eight core “Centurion” AMD FX processor clocked at 5GHz with a 220W TDP. That chip was rumored for a summer 2013 release in limited quantities, and it looks like enthusiasts might be able to get their hands on that chip later this year after all!
Although AMD is not talking, Sweclockers has managed to put together a list of preliminary specifications for the codenamed Centurion processor. Rumors have it that the Centurion chip will be officially named the AMD FX-9000, and that it is a 4-module, 8-core part with a 4.8 GHz base clock and 5.0 GHz turbo clockspeed. It has a total of 8MB L2 cache, and 8MB of L3. Further, this 220W TDP part will support a maximum of DDR3-1866 (officially, before overclocking) and is build on AMD's 32nm SOI HKMG manufacturing process. You will need a beefy air cooler at the minimum to keep this chip happy, but otherwise it should be a fun chip for enthusiasts to tinker with!
