Gigabyte's Force H3X gaming headset sports the 50mm neodymium drivers we have become used to, with a decent frequency response range of 20Hz to 20KHz.  The microphone is a bit different, using two 2mm pickup drivers on each side for a total of four but from the testing Modders Inc performed it did not help with the quality of your recorded audio.  This does not matter so much on a gaming headset but this is perhaps not the best choice for a budding YouTube star.  For audio in gaming Modders Inc does give the headset good marks and they also found it to be very comfortable over long periods of time, definitely worth checking out if you are in the market for a new headset to game with.

GDC 15: AMD Mantle Might Be Dead as We Know It: No Public SDK Planned

Subject: Graphics Cards | March 2, 2015 - 02:31 PM |
Tagged: sdk, Mantle, dx12, API, amd

The Game Developers Conference is San Francisco starts today and you can expect to see more information about DirectX 12 than you could ever possibly want, so be prepared. But what about the original low-level API, AMD Mantle. Utilized in Battlefield 4, Thief and integrated into the Crytek engine (announced last year), announced with the release of the Radeon R9 290X/290, Mantle was truly the instigator that pushed Microsoft into moving DX12's development along at a faster pace.

Since DX12's announcement, AMD has claimed that Mantle would live on, bringing performance advantages to AMD GPUs and would act as the sounding board for new API features for AMD and game development partners. And, as was always trumpeted since the very beginning of Mantle, it would become an open API, available for all once it outgrew the beta phase that it (still) resides in.

mantle1.jpg

Something might have changed there.

A post over on the AMD Gaming blog from Robert Hallock has some news about Mantle to share as GDC begins. First, the good news:

AMD is a company that fundamentally believes in technologies unfettered by restrictive contracts, licensing fees, vendor lock-ins or other arbitrary hurdles to solving the big challenges in graphics and computing. Mantle was destined to follow suit, and it does so today as we proudly announce that the 450-page programming guide and API reference for Mantle will be available this month (March, 2015) at www.amd.com/mantle.
 
This documentation will provide developers with a detailed look at the capabilities we’ve implemented and the design decisions we made, and we hope it will stimulate more discussion that leads to even better graphics API standards in the months and years ahead.

That's great! We will finally be able to read about the API and how it functions, getting access to the detailed information we have wanted from the beginning. But then there is this portion:

AMD’s game development partners have similarly started to shift their focus, so it follows that 2015 will be a transitional year for Mantle. Our loyal customers are naturally curious what this transition might entail, and we wanted to share some thoughts with you on where we will be taking Mantle next:

AMD will continue to support our trusted partners that have committed to Mantle in future projects, like Battlefield™ Hardline, with all the resources at our disposal.

  1. Mantle’s definition of “open” must widen. It already has, in fact. This vital effort has replaced our intention to release a public Mantle SDK, and you will learn the facts on Thursday, March 5 at GDC 2015.
     
  2. Mantle must take on new capabilities and evolve beyond mastery of the draw call. It will continue to serve AMD as a graphics innovation platform available to select partners with custom needs.
     
  3. The Mantle SDK also remains available to partners who register in this co-development and evaluation program. However, if you are a developer interested in Mantle "1.0" functionality, we suggest that you focus your attention on DirectX® 12 or GLnext.

Essentially, AMD's Mantle API in it's "1.0" form is at the end of its life, only supported for current partners and the publicly available SDK will never be posted. Honestly, at this point, this isn't so much of a let down as it is a necessity. DX12 and GLnext have already superseded Mantle in terms of market share and mind share with developers and any more work AMD put into getting devs on-board with Mantle is wasted effort.

mantle-2.jpg

Battlefield 4 is likely to be the only major title to use AMD Mantle

AMD claims to have future plans for Mantle though it will continue to be available only to select partners with "custom needs." I would imagine this would expand outside the world games but could also mean game consoles could be the target, where developers are only concerned with AMD GPU hardware.

So - from our perspective, Mantle as we know is pretty much gone. It served its purpose, making NVIDIA and Microsoft pay attention to the CPU bottlenecks in DX11, but it appears the dream was a bit bigger than the product could become. AMD shouldn't be chastised because of this shift nor for its lofty goals that we kind-of-always knew were too steep a hill to climb. Just revel in the news that pours from GDC this week about DX12.

MWC 15: HP Spectre x360 Has Broadwell Core i5 and i7

Subject: General Tech, Systems, Shows and Expos | March 1, 2015 - 11:07 PM |
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.

MWC 15: LG Demos WebOS Smartwatch ("Urbane LTE")

Subject: General Tech, Mobile, Shows and Expos | March 1, 2015 - 09:46 PM |
Tagged: webOS, smartwatch, mwc 15, MWC, LG

A while ago, LG licensed WebOS from HP for use in their smart TVs and, as we found out during CES, smart watches.

The LG Urbane LTE is one such device, and we can finally see it in action. It is based around (literally) a circular P-OLED display (320 x 320, 1.3-inches, 245 ppi). Swirling your finger around the face scrolls through the elements like a wheel, which should be significantly more comfortable to search through a large list of applications than a linear list of elements -- a lot like an iPod (excluding the Touch and the Shuffle). That said, I have only seen other people use it.

lg-smartwatch-urbane-lte.jpg

The SoC is a Qualcomm Snapdragon 400, clocked at 1.2 GHz. It supports LTE, Wireless-N, Bluetooth 4.0LE, and NFC. It has 1 GB of RAM, which is quite a bit, and 4GB of permanent storage, which is not. It also has a bunch of sensors, from accelerometers and gyros to heart rate monitors and a barometer. It has a speaker and a microphone, but no camera. LG flaunts a 700 mAh battery, which they claim is “the category's largest”, but they do not link that to an actual amount of usage time (only that it “go[es] for days in standby mode”).

Pricing has not yet been announced, but it should hit the US and Europe before May arrives.

GDC 15: Quixel Advertises MEGASCANS with Jungle Scene

Tagged: quixel, GDC, gdc 15, ue4, unreal engine 4, gdc 2015

You know that a week will be busy when companies start announcing a day or two early to beat the flood. While Game Developers Conference starts tomorrow, Quixel published their Jungle demo to YouTube today in promotion of their MEGASCANS material library. The video was rendered in Unreal Engine 4.

Their other material samples look quite convincing. The vines on a wall (column in this case) is particularly interesting because it even looks like two distinct layers, despite being a single mesh with displacement as far as I can tell. I don't know, maybe it is two or three layers. It would certainly make sense if it was, but the top and bottom suggests that it is single, and that is impressive. It even looks self-occluding.

Pricing and availability for the library is not yet disclosed, but it sounds like it will be a subscription service. The software ranges from $25 to $500, depending on what you get and what sort of license you need (Academic vs Commercial and so forth).

HTC Announces Vive VR Headset in Partnership with Valve

Mobile World Congress (MWC) and Game Developers Conference (GDC) severely overlap this year, and not just in dates apparently. HTC just announced the Vive VR headset at MWC, which was developed alongside Valve. The developer edition will contain two 1200x1080 displays with a 90Hz refresh rate, and it will launch this spring. The consumer edition will launch this holiday. They made sure to underline 2015, so you know they're serious. Want more information? Well that will be for Valve to discuss at GDC.

htc-valve-vr.jpg

The confusing part: why is this not partnered with Oculus? When Michael Abrash left Valve to go there, I assumed that it was Valve shedding its research to Facebook's subsidiary and letting them take the hit. Now, honestly, it seems like Facebook just poached Abrash, Valve said “oh well”, and the two companies kept to their respective research. Who knows? Maybe that is not the case. We might find out more at GDC, but you would expect that Oculus would be mentioned if they had any involvement at all.

Valve will host an event on the second official day of GDC, March 3rd at 3pm. In other words, Valve will make an announcement on 3/3 @ 3. Could it involve Left 4 Dead 3? Portal 3? Will they pull a Crytek and name their engine Source 3? Are they just trolling absolutely everyone? Will it have something to do with NVIDIA's March 3rd announcement? Do you honestly think I have any non-speculative information about this? No. No I don't. There, I answered one of those questions.

Samsung has announced the new Galaxy S phones at MWC, and the new S6 and S6 Edge should be in line with what you were expecting if you’ve followed recent rumors.

As expected we no longer see a Qualcomm SoC powering the new phones, and as the rumors had indicated Samsung opted instead for their own Exynos 7 Octa mobile AP. The Exynos SoC’s have previously been in international versions of Samsung’s mobile devices, but they have apparently ramped up production to meet the demands of the US market as well. There is an interesting twist here, however.

14nmOcta.jpg

The Exynos 7420 powering both the Galaxy S6 and S6 Edge is an 8-core SoC with ARM’s big.LITTLE design, combining four ARM Cortex-A57 cores and four Cortex-A53 cores. Having announced 14nm FinFET mobile AP production earlier in February the possibility of the S6 launching with this new part was interesting, as the current process tech is 20nm HKMG for the Exynos 7. However a switch to this new process so soon before the official announcement seemed unlikely as large-scale 14nm FinFET production was just unveiled on February 16. Regardless, AnandTech is reporting that the new part will indeed be produced using this new 14nm process technology, and this gives Samsung an industry-first for a mobile SoC with the launch of the S6/S6 Edge.

GSM Arena has specs of the Galaxy S6 posted, and here’s a brief overview:

  • Display: 5.1” Super AMOLED, QHD resolution (1440 x 2560, ~577 ppi), Gorilla Glass 4
  • OS: Android OS, v5.0 (Lollipop) - TouchWiz UI
  • Chipset: Exynos 7420
  • CPU: Quad-core 1.5 GHz Cortex-A53 & Quad-core 2.1 GHz Cortex-A57
  • GPU: Mali-T760
  • Storage/RAM: 32/64/128 GB, 3 GB RAM
  • Camera: (Primary) 16 MP, 3456 x 4608, optical image stabilization, autofocus, LED flash
  • Battery: 2550 mAh (non-removable)

The new phones both feature attractive styling with metal and glass construction and Gorilla Glass 4 sandwiching the frame, giving each phone a glass back.

So Long Adware, and Thanks for All the Fish!

Tagged: superfish, Lenovo, bloatware, adware

Obviously, this does not forget the controversy that Lenovo got themselves into, but it is certainly the correct response (if they act how they imply). Adware and bloatware is common to find on consumer PCs, which makes the slowest of devices even more sluggish as demos and sometimes straight-up advertisements claim their share of your resources. This does not even begin to discuss the security issues that some of these hitchhikers drag in. Again, I refer you to the aforementioned controversy.

lenovo-do.png

In response, albeit a delayed one, Lenovo has announced that, by the launch of Windows 10, they will only pre-install the OS and “related software”. Lenovo classifies this related software as drivers, security software, Lenovo applications, and applications for “unique hardware” (ex: software for an embedded 3D camera).

It looks to be a great step, but I need to call out “security software”. Windows 10 should ship with Microsoft's security applications in many regions, which really questions why a laptop provider would include an alternative. If the problem is that people expect McAfee or Symantec, then advertise pre-loaded Microsoft anti-malware and keep it clean. Otherwise, it feels like keeping a single finger in the adware take-a-penny dish.

At least it is not as bad as trying to install McAfee every time you update Flash Player. I consider Adobe's tactic the greater of two evils on that one. I mean, unless Adobe just thinks that Flash Player is so insecure that you would be crazy to install it without a metaphorical guard watching over your shoulder.

And then of course we reach the divide between “saying” and “doing”. We will need to see Lenovo's actual Windows 10 devices to find out if they kept their word, and followed its implications to a tee.

Ahead of MWC, 2015 Is Shaping up to Be a Good Year for Low-Cost Smartphones

Subject: Mobile | February 28, 2015 - 04:42 PM |
Tagged: smartphones, MWC 2015, MWC, Moto E, LG Magna, ios, Android 5.0

Last year my favorite smartphone became the 2014 version of the Moto G. This was (and still is) a $179 unlocked Android phone that shipped with 4.4.4 KitKat, but recently received an OTA update to 5.0 Lollipop (and subsequently 5.0.2 via a second OTA update). Motorola’s aggressive pricing made the phone compelling on paper, but using the device was even more impressive. It looked good, with a 5-inch 720p IPS display and the same design language as the Moto X and later Nexus 6, and ran a virtually untouched stock Android OS. It was never going to win any awards for raw speed, but the quad-core Snapdragon 400 SoC was plenty fast for daily use. The main drawback was a glaring one, however: the Moto G was not LTE capable. Enter the new Moto E.

Screenshot_2015-02-28-16-19-06~2.jpg

The Moto E 2nd Edition

Here are some quick specs from Motorola:

Moto E 2nd Edition (LTE capable)
4.5” 540x960 display
Android 5.0.x
Snapdragon 410
Quad-core 1.2GHz Cortex-A53/Adreno 306
1GB RAM/8GB storage
2390 mAh battery
Unlocked, $149

We are already off to a solid start in 2015 with a great option from Motorola in the new 2nd edition Moto E. This LTE capable smartphone might look a little chunky, but the specs make it more that just a compelling option at $149 (unlocked) as it could have the disruptive impact on price that Microsoft just couldn’t make last year with their inexpensive Lumia phones. With 2015’s Mobile World Congress (MWC) fast approaching the Moto E has already been making some noise in the affordable phone space that last year’s Moto G played a big part in, and this time the message is clear: in 2015 a smartphone needs to have LTE, regardless of price.

To be fair Microsoft has already addressed need for LTE with their low-cost Windows Phone devices like the Lumia 635 (which is actually selling for just $49 on Amazon now), but the app ecosystem for the platform is just too restrictive to make it a viable solution compared to Android and iOS. Honestly, I love the Windows Phone OS but there are too many missing apps to make it a daily driver. So, since Windows clearly isn’t the answer and Apple won’t be selling a sub-$200 unlocked smartphone anytime soon (the cheapest unlocked iPhone is the 8GB 5c at $450), that leaves Android (of course).

phpocsjju~2~2.jpg

LG's 2015 mid-range smartphone lineup

Another possibility comes from LG, as ahead of MWC there was a press release from the company showcasing their new “mid-range” smartphone lineup for 2015. Among the models listed is another phone that matches the specs associated with a $200-ish unlocked phone, but pricing has not been announced yet.

LG Magna (LTE capable) - Unreleased
5.0” 720x1280 display
Android 5.0.x
Quad-core 1.2/1.3GHz
1GB RAM, 8GB storage
2540 mAh battery

We await the announcements from MWC and there are sure to be many other examples of low-cost LTE devices, but already it’s looking like it won’t take more than $200 and a SIM card to avoid the endless device upgrade cycle in 2015.

New Intel NUC Will Feature i7 Broadwell-U CPU With Iris 6100 Graphics

Subject: General Tech | February 27, 2015 - 04:41 PM |
Tagged: SFF, nuc5i7ryh, nuc, Intel, broadwell-u, Broadwell

We recently reviewed a new small form factor NUC PC from Intel powered by Broadwell. That i5-powered NUC5i5RYK will soon be joined by an even higher end Broadwell NUC (NUC5i7RYH) equipped with an i7-5557U CPU and Iris 6100 graphics.

According to FanlessTech, this slightly thicker NUC will come as a barebones system with a processor, motherboard, and wireless card pre-installed in a case with customizable lids (to add NFC, wireless charging, or other features). Note that, unlike the Broadwell i5 version we reviewed, this model supports 2.5” SSDs.

i7 Broadwell NUC Features Iris 6100 Graphics.png

External I/O includes:

  • Front:
    • 2 x USB 3.0 ports (one charging capable)
    • 1 x Audio jack
    • 1 x IR sensor
  • Rear:
    • 2 x USB 3.0 ports
    • 1 x Gigabit Ethernet RJ45
    • 1 x Mini HDMI 1.4a
    • 1 x Mini DisplayPort 1.2

Internally, the NUC5i7RYH is powered by a dual core (with Hyper-Threading) i7-5557U processor clocked at 3.1 GHz base and 3.4 GHz turbo with 4MB cache and 28W TDP. The processor also features Intel’s Iris 6100 GPU which our own Scott Michaud estimates it at 48 execution units and 845 GFLOPS of performance. He further speculates that it gets to a similar level of theoretical performance as the Intel Iris 5100 graphics (used in Haswell CPUs) using more (but lower clocked at up to 1050 MHz) shaders.

The Iris 6100 GPU is likely to be the highest processor graphics we will see with Broadwell-U. It supports 4K resolutions at 24Hz as well as video decode (though apparently not hardware accelerated) of VP8, VP9, and H.265 (HVEC) via wired displays or over Intel’s WiDi wireless display technology. Further, the GPU supports DirectX 12 in its current iteration as well as OpenGL 4.3 and OpenCL 2.0.

Internal connectivity includes support for two DDR3L SODIMMs (up to 16GB), a single 2.5” solid state drive, one M.2 SSD, an Intel Wireless AC 7265 card (802.11ac+BT), a NFC header, and a header for two USB 2.0 ports.

Intel has not released pricing, but expect it to hit at least $500 since the i5 version without Iris graphics has an MSRP of $399. It is slated to arrive soon with a launch window of Q2 2015.

If 4G speeds of 400Mbps become common there are going to be some very happy media streamers, at least until the bill comes in.  In a proof of concept test Huawei EE and Qualcomm demonstrated a 4G LTE carrier aggregated connection in Wembley stadium which hit peak speeds of 400Mbps and should provide most attendees of events at Wembley with speeds hitting up to 150Mbps. The carrier will use the existing 4G LTE network, only tweaking was needed to increase the speeds as opposed to a new standard and so any phone capable of connecting to LTE should be able to take advantage of the speed increase.  Check out The Inquirer for more information.

Imagination Launches PowerVR GT7900, "Super-GPU" Targeting Consoles

Subject: Graphics Cards, Mobile | February 26, 2015 - 02:15 PM |
Tagged: super-gpu, PowerVR, Imagination Technologies, gt7900

As a preview to announcements and releases being made at both Mobile World Congress (MWC) and the Game Developers Summit (GDC) next week, Imagination Technologies took the wraps off of a new graphics product they are calling a "super-GPU". The PowerVR GT7900 is the new flagship GPU as a part of its Series7XT family that is targeting a growing category called "affordable game consoles." Think about the Android-powered set-top devices like the Ouya or maybe Amazon's Kindle TV.

gt7900-1.png

PowerVR breaks up its GPU designs into unified shading clusters (USCs) and the GT7900 has 16 of them for a total of 512 ALU cores. Imagination has previously posted a great overview of its USC architecture design and how you can compare its designs to other GPUs on the market. Imagination wants to claim that the GT7900 will offer "PC-class gaming experiences" though that is as ambiguous as the idea of a work load of a "console-level game." But with rated peak performance levels hitting over 800 GFLOPS in FP32 and 1.6 TFLOPS in FP16 (half-precision) this GPU does have significant theoretical capability.

  PowerVR GT7900 Tegra X1
Vendor Imagination Technologies NVIDIA
FP32 ALUs 512 256
FP32 GFLOPS 800 512
FP16 GFLOPS 1600 1024
GPU Clock 800 MHz 1000 MHz
Process Tech 16nm FinFET+ 20nm TSMC

Imagination also believes that PowerVR offers a larger portion of its peak performance for a longer period of time than the competition thanks to the tile-based deferred rendering (TBDR) approach that has been "refined over the years to deliver unmatched efficiency."

gt7900-2.png

The FP16 performance number listed above is useful as an extreme power savings option where the half-precision compute operates in a much more efficient manner. A fair concern is how many applications, GPGPU or gaming, actually utilize the FP16 data type but having support for it in the GT7900 allows developers to target it.

Other key features of the GT7900 include support for OpenGL ES 3.1 + AEP (Android Extension Pack), hardware tessellation and ASTC LDR and HDR texture compression standards. The GPU also can run in a multi-domain virtualization mode that would allow multiple operating systems to run in parallel on a single platform.

gt7900-3.png

Imagination believes that this generation of PowerVR will "usher a new era of console-like gaming experiences" and will showcase a new demo at GDC called Dwarf Hall.

I'll be at GDC next week and have already setup a meeting with Imagination to talk about the GT7900 so I can have some hands on experiences to report back with soon. I am continually curious about the market for these types of high-end "mobile" GPUs with the limited market that the Android console market currently addresses. Imagination does claim that the GT7900 is beating products with performance levels as high as the GeForce GT 730M discrete GPU - no small feat.

  4. Question: Alex from Sydney
    1. Just a quick question regarding DirectX 12. I’m planning to buy a new graphics card soon but I want a DirectX 12 card for all the fancy new features so I’m considering either the GTX 970 or 980, the question I have is are these real DirectX 12 cards? Since DirectX 12 development is still ongoing how can these cards be fully DirectX 12 complaint?

SIM card maker Gemalto apparently now holds the world's record for fastest security audit?

In just under a week SIM card maker Gemalto claims to have done a complete security audit of their systems in 85 different countries and reports that "its office networks were compromised, the servers holding the SIM card encryption keys weren't."  This is a  record worthy of Guinness as most security audits take months or years to complete and the findings tend to discuss probabilities, not absolute certainties.  As you might expect The Register and security experts everywhere are doubtful of the claims from a company that did not even know if was compromised less than a week ago that the UK based GCHQ and USA based NSA are unable to compromise your SIM cards encryption when they have the keys in hand.  It has not been a good week for anyone who thinks about security.

"Six days ago Gemalto, the world's largest SIM card manufacturer, was told that back in 2010 it had been ransacked by NSA and GCHQ hackers. Today the company gave itself the all-clear: no encryption keys, used to secure phone calls from eavesdroppers, were stolen, it claims."

Windows 10 Technical Preview Build 10022 Spotted

Tagged: windows 10, windows, microsoft

WZor, a group in Russia that somehow acquires many Windows leaks, has just published screenshots of Windows 10 Build 10022 and Windows Server Build 9926. As far as we can tell, not much has changed. We see neither an upgraded Cortana nor a look at the Spartan browser. The build is not labeled “Microsoft Confidential” though, which makes people believe that it is (or was) intended for public release -- maybe as early as this week.

Honestly, I do not see anything different from the provided screenshots apart from the incremented version number. It is possible that this build addresses back-end issues, leaving the major new features for BUILD in late April. Leaked notes (also by WZor) for build 10014, called an “Early Partner Drop”, suggest that version was designed for hardware and software vendors. Perhaps the upcoming preview build is designed to give a platform for third-parties to develop updates ahead of Microsoft releasing the next (or second-next) big build?

Either way, it seems like we will get it very soon.

Intel Revamps Atom Branding, Next Generation Atoms Will Come in x3, x5, and x7 Tiers

Intel is updating its Atom processor branding to better communicate the expected performance and experience customers can expect from their Intel powered mobile device. In fact, the new branding specifies three tiers. Atom processors will soon come in Atom x3, x5, and x7 flavors. This branding scheme is similar to the Core processor branding using the i3, i5, and i7 labels.

The Atom x3, x5, and x7 chips are low power, efficient processors for battery powered devices and sit below the Core M series which in turn are below the Core i3, i5, and i7 processors. The following infographic shows off the new branding though Intel does not reveal any specific details about these new Atom chips (we will hopefully know more after Mobile World Congress). Of course, Atom x3 chips will reside in smartphones with x5 and x7 chips powering tablets and budget convertibles. The x7 brand represents the flagship processors of the Atom line.

The new branding will begin with the next generation of Atom chips which should include Cherry Trail, the 14nm successor to Bay Trail featuring four x86 Airmont cores and Gen 8 Intel graphics. Cherry Trail (Cherryview SoC) will be used in all manner of mobile devices from entry level 8"+ tablets to larger notebooks and convertibles. It appears that Intel will use Moorefield (a quad core 14nm refresh of Merrifield) through 2015 for smartphones though road maps seem to indicate that Intel's budget SoFIA SoC will also launch this year. SoFIA and Moorefield processors should fall under the Atom x3 brand with the higher powered and higher clocked Cherry Trail chips will use the Atom x5 and x7 monikers.

What are your thoughts on Intel's new Atom x3/x5/x7 brands?

Intel Sheds Its Remaining Stake In Imagination Technologies

Update: Currency exchange rates have been corrected. I'm sorry for any confusion!

Intel Foundation is selling off its remaining stake in UK-based Imagination Technologies (IMG.LN). According to JP Morgan, Intel is selling off 13.4 million shares (4.9% of Imagination Technologies) for 245 GBp each. Once all shares are sold, Intel will gross just north of $50.57 Million USD.

Imagination Technologies' PowerVR Rogue Series 6XT GPU is used in Apple's A8-series chips.

Intel first invested in Imagination Technologies back in October of 2006 in a deal to gain access to the company’s PowerVR graphics IP portfolio. Since then, Intel has been slowly moving away from PowerVR graphics in favor of it’s own internal HD graphics GPUs. (Further, Intel sold off 10% of its IMG.LN stake in June of last year.) Even Intel’s low cost Atom line of SoCs has mostly moved to Intel GPUs with the exception of the mobile Merrifield and Moorefield” smartphone/tablet SoCs.

The expansion of Intel’s own graphics IP combined with Imagination Technologies acquisition of MIPS are reportedly the “inevitable” reasons for the sale. According to The Guardian, industry analysts have speculated that, as it stands, Intel is a minor customer of Imagination Technologies at less than 5% for graphics (a licensing agreement signed this year doesn’t rule out PowerVR graphics permanently despite the sale). Imagination Technologies still has a decent presence in the mobile (ARM-based) space with customers including Apple, MediaTek, Rockchip, Freescale, and Texas Instruments.

Currently, the company’s stock price is sitting at 258.75 GBp (~$3.99 USD) which seems to indicate that the Intel sell off news was “inevitable” and was already priced in or simply does not have investors that concerned.

What do you think about the sale? Where does this leave Intel as far as graphics goes? Will we see Intel HD Graphics scale down to smartphones or will the company go with a PowerVR competitor? Would Intel really work with ARM’s Mali, Qualcomm’s Adreno, or Samsung’s rumored custom GPU cores? On that note, an Intel powered smartphone with NVIDIA Tegra graphics would be amazing (hint, hint Intel!)
