    Samsung, MediaTek, Huawei and even Qualcomm are now in the octa-core SoC game, but there's always space for more. The latest member is China's Allwinner Technology, who's best known for making the chipsets inside many low-end devices. Like most of its competitors, Allwinner's UltraOcta A80 silicon (pictured above on a development board) uses ARM's big.LITTLE heterogeneous multi-processing design, meaning it can simultaneously run on all eight cores -- four low-power Cortex-A7 and four high-end Cortex-A15. The chip also features Imagination Technologies' 64-core PowerVR G6230 GPU, which promises to deliver "a twofold increase in graphics" performance when compared to Allwinner's previous flagship SoC, the A31 series. We'll spare you from all the nitty-gritty, but you can learn more in the source links below. Expect to see the UltraOcta A80 in affordable devices "in the next few months."

    As a follow to NVIDIA's Tegra 3 reference design for tablets, the company is now unveiling a more ambitious platform known as Tegra Note that leverages the Tegra 4, supports stylus input and provides new multimedia features. Like Project Kai, tablets based on the Tegra Note platform carry a suggested retail price of $199, but pricing is ultimately up to NVIDIA's manufacturing partners and their various hardware configurations. If this all sounds a bit familiar to you, it should. We first saw signs of NVIDIA's new tablet platform when it appeared as the Tegra Tab at the FCC, and then again in subsequent leaks. Manufacturers can easily apply their name to the reference enclosure, which houses front-facing speakers, a 7-inch, 1,280 x 800 IPS display and a VGA webcam. Naturally, you're also getting the Tegra 4 SoC, which includes a quad-core Cortex-A15 CPU, a 72-core GeForce GPU and advanced imaging features under the Chimera architecture. Other specs will depend on manufacturers, which could include a 5-megapixel rear camera, a microSD slot, a micro-HDMI port and a built-in stylus that offers both chisel and brush tips. Along with the hardware reference design, NVIDIA is also including Camera Awesome from SmugMug and TegraZone in the Tegra Note platform (along with stylus-enabled apps on appropriate models), and it's even managing the Android system updates. You can expect the first of these Tegra Note tablets to hit shelves in October from the likes of EVGA, PNY and ZOTAC, along with a full line of accessories that include covers and interchangeable stylus tips.

  • MediaTek's MT8135 SoC does dual-core big.LITTLE MP, packs PowerVR Series6 GPU

    It'll be a while before MediaTek's true octa-core SoC makes its glorious arrival, but for the time being, the company's unveiling something just as interesting -- and perhaps more practical. The new MT8135 announced today is a "quad-core" SoC aimed at "the middle- to high-end tier of the tablet OEM market." We quote "quad-core," because it actually consists of two clusters: dual Cortex-A15 cores and dual Cortex-A7 cores. But the good news is that unlike the original big.LITTLE configuration where only one cluster can operate at any given time (depending on how heavy the workload is), MediaTek's confirmed that it has implemented big.LITTLE MP ("MP" as in heterogeneous multi-processing) in the MT8135, meaning both the A15 and the A7 clusters can operate simultaneously. Another highlight of this MT8135 is that it'll be one of the first SoCs -- alongside LG's H13 (which we've seen first-hand), Renesas' APE6 and Renesas' R-Car H2 -- to come with Imagination Technologies' almighty PowerVR Series6 GPU. Specifically, this is the PowerVR G6200 which, as part of the MT8135, can apparently deliver "up to four times more ALU (arithmetic logic unit) horsepower" than the Series5XT GPU on the cheaper, quad-A7 MT8125. And unsurprisingly, the MT8135 gets the same Miracast wireless video goodie given to the MT8125; though it's also worth noting that the latter only supports LPDDR2 RAM instead of the more powerful LPDDR3. Sadly, there's no further information regarding availability, but you can kill some time by checking out more technical details in the video (with benchmarks; even though Qualcomm's been mysteriously left out) and press releases after the break.

  • New Exynos 5 Octa: 20 percent more CPU power, over twice the 3D graphics oomph

    Samsung couldn't help itself last week when it teased a new Exynos 5 Octa system on a chip, and now it's dishing out the full details. The fresh 5420 variant of the SoC is based on Mali-T628 MP6 silicon, packs a quartet of ARM Cortex-A15 cores running at 1.8GHz and four 1.3GHz Cortex-A7s in an ARM big.LITTLE configuration. Seoul claims that the package packs 20 percent more CPU processing punch, and has two times greater 3D graphics power than its predecessor. Dual-channel LPDDR3 at 933MHz gives the processor a screaming memory bandwidth of 14.9 GBps, which lends it full HD WiFi display support. Baked inside is an image compression solution that makes for energy efficient multimedia loading, and squeezes out more hours of use with high-res displays. There's no word on which devices might use the new SoCs, but the chips are already being sampled by Samsung's customers, and mass-production is slated for August.

    That Galaxy S 4 isn't going to compute tasks through sheer force of will, you know. Just a day after Samsung unveiled the smartphone as its inaugural Exynos 5 Octa device, the company has confirmed that the not-really-eight-core ARM processor should be in mass production during the second quarter of the year, or between April and June. There aren't many more details to share beyond what the company mentioned at CES, but that doesn't diminish what could be a best-of-all-worlds processor: the automatic switching between four Cortex-A15 and four Cortex-A7 cores should give it a performance edge over many of its peers while reducing power consumption by up to 70 percent. We also know that the Octa's graphics performance has largely caught up to peers versus earlier Exynos 4 designs, as Imagination Technologies has confirmed that its PowerVR SGX544MP is providing enough muscle to double 3D performance over the creaky Mali-400 in the Exynos 4 Quad. About the only mystery left is whether or not many companies beyond Samsung will get a chance at some Exynos 5 Octa silicon, although there's one or two prospects.

    We never thought our day could get any better after Huawei's Consumer Business Group CEO Richard Yu became available again for our CES stage interview (there was originally a "last minute urgent conflict"), but our man was also kind enough to share a couple more scoops with us. First of all, Huawei will be joining Samsung at the octa-core Cortex-A15 party in the second half of this year, and given what Yu's told us earlier this week, our guess is that this will either be the HiSilicon K3V3 or a sister chipset, again manufactured by TSMC. The second scoop of the day was delivered fresh off the stage after the interview. Yu told us exclusively that at MWC next month, Huawei will be unveiling a super slim follow-up to the current P series Android phones. We asked if it'll be even thinner than 6.45mm (the thickness of the Alcatel One Touch Idol Ultra announced at CES), and Yu said yes. The exec added that the new phone will have a beautiful metallic body as well. Exciting times, right?

    Earlier today our brethren over at Engadget Chinese got to hang out with Huawei Device chairman Richard Yu, who was kind enough to inform us that his company will release a HiSilicon K3V3 chipset -- the follow-up to the current quad-core K3V2 -- in the second half of this year. What's more, much like NVIDIA's upcoming Tegra 4, the new platform will be based on the more powerful Cortex-A15 ARM architecture instead of Cortex-A9. Yu also hinted that the K3V3 will be featured in the successors to the Ascend D2 and the Ascend Mate, but our guess is that we won't be seeing those at MWC next month. We shall tickle the man live on stage for more answers this Thursday.

    Linux wizard Michael Larabel has been marking his benches over at Phoronix and in the process he's proved that the Samsung Exynos 5 Dual processor -- currently found in some of our favorite tablets and budget notebooks -- is remarkably nifty with Ubuntu. The chip, which contains two Cortex-A15 cores clocked at 1.7GHz and a Mali-T604 GPU, was stacked up against the A9-based Tegra 3 from NVIDIA plus a few Intel Atoms to represent the x86 side of things. Although the various test rigs couldn't be totally spec-matched in terms of RAM and storage, the scores were focused on pure computational grunt and they gave Samsung's SoC a "surprising" lead. Check out the source link below and you'll see that the majority of the graphs look similar to the one above, with the two weaker Atoms and the aging Tegra 3 being left for dust and only the Core i3, with its much higher wattage, being able to keep that Exynos ego in check -- at least until the eight-core version gets here.

  • Samsung to outline 8-core big.LITTLE ARM processor in February

    Samsung's processor design team has been on a roll with fast chips this year with the Exynos 4 Quad and Exynos 5 Dual. Based on its agenda for the International Solid-State Circuits Conference, that momentum isn't about to stop. A company presentation at the event on February 19th will delve into a new heterogeneous, 8-core processor that relies on ARM's concept of big.LITTLE computing: one half is a quad-core, 1.8GHz ARM Cortex-A15 that will do all the heavy lifting, while the other is a quad 1.2GHz Cortex-A7 that takes over in quieter moments. We don't know much more about the chip beyond the expected 28-nanometer manufacturing process, but it's easy to see a mobile chip that's fast without having to consume much energy in its downtime. Most of the mystery surrounds where Samsung will launch the processor first, rather than what it can do: the big.LITTLE chip would be most valuable in a smartphone, but a potentially large size could relegate it to tablets early on.

    Unless we're looking at one of the most elaborately photographed fakes in the world, this is the Nexus 10. With the Nexus 7 apparently going over quite well at just $199, it was only ever a matter of time before the Nexus family expanded to house a 10-incher. With Google's own Vic Gundotra posting images from a unit that he's using at some exotic locale, it seems that another unit has slipped beneath the camera at BriefMobile. The site has managed to apprehend one of the 10.1-inch slates, and in turn has discovered quite the bounty of information. Internally, there's (reportedly) a dual-core, Cortex-A15-based 1.7GHz Samsung Exynos 5250, a Mali-T604 GPU, 2GB of RAM, 16GB of internal storage (though no microSD expansion slot), a 5 megapixel rear-facing camera, NFC / WiFi, Bluetooth 4.0 and a Super AMOLED panel with a drool-worthy 2,560 x 1,600 screen resolution -- yeah, that's well into "Retina" territory at 298.9 pixels per inch. You may recognize that Exynos 5250 from Google's recently released $249 Chromebook, but here, it's being used to push Android 4.2. Those hungry for more can visit the source link, but don't go in hoping to extract an asking price. Update: Well, if the pictures weren't enough, BriefMobile has just popped a five-second long video of the device, which you can glance at after the break. Don't get too excited, however, as it's merely just someone going from the home screen into Chrome.

  • iPhone 5: the rumor roundup

    We're on the cusp of Apple's sixth iPhone launch, and there's very different expectations than there were last year. The 2011 rumor cycle left more than a few people burned: the later-than-usual October launch and repeated claims of a heavily-remade design led some to a disappointment when the iPhone 4S arrived, even though the final product had a slew of camera, speed and voice command upgrades. This year, the rumors have been grounded well before there was an event date in our hands. There have been fewer instances of wild rumors. Instead, it's been based more around pragmatism, using either tangible leaks or sources that have a solid track record. Think of the perennial leaks from the Wall Street Journal or the increasingly well-established sourcing from iMore and The Loop. Whether you're conspiracy-minded or not, it's been hard to ignore the sheer number of claims that have tamped down expectations rather than inflated them. It's as though there's a collective fear we'll see a repeat of the 2011 hysteria and deal with fans (or detractors) complaining about missing features that were never promised in the first place. Where last summer was full of uncertainty, this year there's a mounting consensus as to what we'll see, how we'll get it, and when. Tracking everything that's been mentioned may be a handful, however. With that in mind, we'll dive in and gauge what's likely to emerge from behind Apple's curtain on September 12th -- as well as what we can rule out from the get-go.

    Our SIGGRAPH demo of the ARM Mali-T604 GPU gave a brief preview of Samsung's upcoming Exynos 5 Dual CPU, but now all the details of the company's next great processor are ready for us to view. Other than that GPU which includes support for up to WQXGA (2,560 x 1,600) resolutions -- perfect for the 11.8-inch P10 mentioned in court filings -- and much more, the white paper uncovered by Android Authority also mentions support for features like Wi-Fi Display, high bandwidth LPDDR3 RAM running at up to 800MHz with a bandwidth of 12.8GBps, USB 3.0 and SATA III. It also claims the horsepower to decode 1080p video at 60fps in pretty much any codec, stereoscopic 3D plus handle graphics APIs like OpenGL ES 3.0 and OpenCL 1.1. All of this is comes courtesy of a dual-core 1.7GHz ARM Cortex-A15 CPU built on the company's 32nm High-K Metal Gate process and Panel Self Refresh technology that avoids changing pixels unnecessarily to reduce power consumption. There's plenty of other buzzwords and benchmarks floating around in the PDF, you can check them out in the PDF linked below or just sit back and see what tablets and phones arrive with one of these -- or the competition from Qualcomm's S4 and NVIDIA's Tegra -- inside starting later this year.

    Think those are some pretty slick graphics in your Galaxy S III? Samsung's latest smartphone packs some mighty graphics prowess of its own, thanks to the Mali-400 MP GPU, but once you spend a few minutes with the Mali-T604, the company's next-generation chipset, the improvements become quite clear. After seeing the Mali-T604 in action, as we did at SIGGRAPH today, the capabilities leave us hopeful for the future, and perhaps feeling a bit self-conscious about the silicon currently in our pockets. The reference device on hand was operating in sync with a variety of unnamed hardware, protected from view in a relatively large sealed box. We weren't able to squeeze many details out of ARM reps, who remained mum about the demo components, including clock speed, manufacturer and even fabrication size. What we do know is that we were looking at a quad-core Mali-T604 and dual-core ARM Cortex-A15 processor, with a fabrication size in the range of "28 to 40 nanometers" (confirming the exact size would reveal the manufacturer). Clock speed is also TBD, and the early silicon on demo at the show wasn't operating anywhere close to its top end. In order to experience the T604, we took a look at three demos, including Timbuktu 2, which demonstrates elements like self shadowing and depth of field with OpenGL ES 3.0, Hauntheim, which gives us an early look at physics simulation and HDR lighting with OpenCL, and Enlighten, which rendered silky smooth real-time illumination. You can see all of the demos in action after the break, and you can expect T604-equipped devices to make their debut beginning later this year -- ARM says its working with eight manufacturers to get the licensed tech to market as early as Q3. Update: ARM has just confirmed to us that this reference device is running off an Exynos 5 Dual chip (up to 1.7GHz), which means the following video is also a heads-up on what Sammy has in store for us in its forthcoming devices.%Gallery-161934%

    Never mind Huawei's 6.68mm-thick Ascend P1 S or Oppo's 6.65mm-thick Finder, because the record's about to be beaten yet again by another Chinese manufacturer. Codenamed "Athena," this mysterious ZTE phone's been getting a fair bit of attention on Sina Weibo with its 6.2mm slimness claim, all thanks to a keen terminal device strategy director from the company. While Mr. Lu hasn't delved into specifics, what we know so far is that Athena will feature a 720p display, Cortex-A15 chip (a source of ours said it will be multi-core) and up to 64GB of internal storage, as well as a "Miflavor UI" -- something that we've already previewed on the Era at MWC -- to go on top of Android 4.0. Lu also hinted that there will be several color options, but we're more than happy to nab that black kevlar edition in the above shot (and someone should tell Motorola to take a look at this). Two more pictures after the break to keep you busy for the time being.

    It's pretty much a year to the day that we reported the possibility of a quad-core Cortex-A15 from ARM, and look what just came across the wire! It's the Cortex-A15 Hard Macro -- the first design from ARM we're aware of that packs four A15 cores. The Hard Macro edition is of particular interest as it aims to help manufacturers bring products to market more quickly and at a lower cost. The chip variant runs at 2GHz, with performance of over 20,000 DMIPS if you were wondering. Notably, it operates with the same power usage of the A9 hard macro, which should mean it's got good efficiency credentials, and it's the first in the family to be based on 28nm process. There's no indication where we might see this turning up, but with the firm spilling the full details at the IEEE Symposium later this week, we're sure we'll find out soon enough.

    ARM is famous for its low-power chip designs, Gemalto is known for its NFC security features, and Giesecke & Devrient brings some nice nano-SIM notoriety to the table. As a trio, these companies want to push forward a security standard that could be readily used in a wide range of web-connected devices, including tablets, smart TVs, game consoles and smartphones. The standard itself is built on ARM's TrustZone hardware-based security, which has been around for a while and is built into every ARM Cortex-A series processor, but which still isn't as widely used as it could be. By founding an off-shoot company with its partners, ARM hopes to nudge the things along faster and turn TrustZone into the "Blu-ray" of mobile security standards.

    Did the murmurings about a quad-core Galaxy S III this morning leave you feeling a bit... meh? We don't blame you. Sure, four cores and integrated LTE sounds great but (and this is a big "but"), Cortex-A9 is old hat. What we really want to hear about are those upcoming Cortex-A15 chips. Well, this should get your blood flowing -- a slide has leaked, allegedly loaded with detailed Exynos 5 specs. Looks like initial entrants will have a pair of A15 cores running at 2GHz, backed up by a quad-core Mali T-604 MP4 GPU. All of that will supposedly be built with Samsung's new 32nm High-K Metal Gate process. We've been unable to independently verify these details, but they are in line with what we've been led to expect. Still, until some Sammy PR comes down the pipeline we're taking everything with a grain of salt.[Thanks, John]

    It's TI's time to brag. We first met OMAP5 when the company's VP of the OMAP division, Remi El-Ouazzane, unveiled the developer's reference platform on our stage at CES. While there, he boasted OMAP5 as "the greatest platform on Earth right now," but we were given only a few insights into the platform's capabilities. Now, TI is back with a new wave of demos that better show the prowess of OMAP5 -- a system-on-chip design that houses a dual-core ARM Cortex-A15 CPU clocked at just 800MHz, two Cortex-M4 cores for low-power processes, along with a PowerVR SGX 544 GPU that handles 3D compositions, and a number of accelerators such as TI's IVA-HD, which supports both video encoding and decoding and plays 1080p video at a whopping 60fps. We were shown a demo of all these capabilities humming in unison on a 1080p display, along with a complex HTML5 mashup that adds credence to the company's latest benchmark report. Photography geeks should know the system supports up to 14 megapixel cameras, and is able to process ten shots per second at that setting. We're told to expect devices based on the OMAP5 platform by the end of the year, and if you're anything like us, it's going to be one hell of a wait. Hop the break for the demo.

    Well, if our hands-on at CES didn't sell you on TI's next-gen OMAP 5 platform, perhaps some more specs revealed recently at MWC 2012 will. We've known about its dual Cortex-A15 and Cortex-M4 architecture since this time last year, but we didn't know that those M4 cores are there to handle real-time processing of multimedia -- like video encoding and decoding -- which TI claims can provide up to ten percent power savings. Additionally, the company's wunderkind SoC will pack a dual-core PowerVR SGX544 GPU and a dedicated 2D hardware-accelerated composition engine to deliver great graphics and lower power consumption than other mobile silicon solutions. OMAP 5 also comes with a multi-tasking image signal processor that can use up to four image sensors at the same time, or take 1080p 60fps video while snapping 12-megapixel stills simultaneously. So, you ready for a super-speedy OMAP 5 chip in your next smartphone yet? Those who are still skeptical can peruse the PR after the break for a full rundown of its considerable capabilities.

    Sammy's current Cortex A9-based chips are hardly slackers -- the Galaxy Note already proved that to any lingering doubters. Nevertheless, the next-gen Exynos 5250 SoC promises to double that sort of performance, by harnessing two Cortex-A15 chips clocked at 2GHz each, along with a GPU that can output resolutions of up to 2560 x 1600 (WQXGA). It's like big.LITTLE computing, except without the LITTLE. Samsung reckons it'll start mass producing the 5250 for use in high-end tablets by the second quarter of next year, which should be just in time to stop NVIDIA from getting too cocky.
