One of the downsides to Microsoft’s ARM-powered Windows RT operating system is the lack of desktop applications. While Windows RT devices to retain the traditional Windows desktop, only Microsoft applications that come pre-packaged with Windows are allowed to run. Instead, Microsoft wants users to stick to Modern UI applications and the Windows Store to get new apps. (Granted, the ARM hardware powering these devices necessitates porting x86 desktop applications in order to run in the first place, but Windows RT locks out even recompiled apps).

Enthusiasts are working on changing that, however. A XDA Developers forum member known as Netham45 recently released a tool that allows users to run unsigned desktop applications on Windows RT. The new RT Jailbreak tool is a batch file that automates a hack discovered by another hacker known as clrokr.

The hack is currently only temporary, and needs to be redone after every computer restart. It does, however, allow Windows RT to run unsigned code on the desktop. After downloading the batch file, you run the runExploit.bat and follow the prompts. After it completes, you users can run recompiled desktop apps such as PuTTY, 7-zip, TightVNC, DOSBox, Quake 2, and more

While it is not a permaent solution, it is a step in the right direction, and makes ARM-powered Windows RT devices a lot more interesting and useful to power users. For more information on the RT Jailbreak hack, and to grab the batch file to unlock your WinRT tablet, check out this forum thread on the XDA Developers website

Qualcomm introduced two new high end mobile processors at CES earlier this week. Known as the Snapdragon 600 and Snapdragon 800, the new SoCs take the company’s Krait CPU cores to the next level. Both of the new chips are based on a 28nm HPm manufacturing process and feature faster (and more efficienct) CPU and GPU portions.

The Qualcomm Snapdragon 600 is SoC with four Krait 300 CPU cores clocked at 1.9GHz along with an Adreno 320 GPU, and 4G LTE modem. The Snapdragon 600 also supports LPDDR3 RAM. The Adreno 320 GPU features suport fro OpenGL ES 3.0, OpenCL, and Renderscript Compute technologies. According to Qualcomm, the Snapdragon 600 is 40% faster than the Snapdragon S4 Pro processor used in devices like the Google Nexus 4 smartphone. Also, the Adreno 320 GPU is up to 3-times faster than the previous-generation A225.

The Snapdragon 600 SoC is inteded for smartphones, and we should start to see the new processor shipping with new devices by Q2 2013.

Meanwhile, the Snapdragon 800 processor takes performance up yet another notch over the company’s existing chips. The new SoC includes four Krait 400 CPU cores clocked at 2.3GHz, an Adreno 330 GPU, support for 2x32-bit LPDDR3 at 800MHz (12.8Gbps), and a 4G LTE modem. The chip also features two image signal processors (ISP) that can handle up to four cameras and 55MP (total) resolution. Devices with the Snapdragon 800 processor will be able to record 1080p30 video as well as encode and decode stored videos with up to 4K resolutions. As far as wireless, the Snapdragon 800 includes a 4G LTE modem and 802.11ac Wi-Fi. The upcoming SoC can handle 4K video output and HD audio in the form of DTS-HD, Dolby Digital+, and 7.1 Surround Sound.

The Adreno 330 GPU in the Snapdragon 800 chip also supports OpenGL ES 3.0, OpenCL, and Rednderscript Computer technologies. It can output 4K video and reportedly offers up to twice the compute performance versus the Adreno 320 GPU in the Snapdragon 600 processor.

According to Qualcomm, the Snapdragon 800 processor as a whole is up to 75% faster than the Snapdragon S4 Pro SoC. Qualcomm is aiming this processor at “premium” high end devices including Smart TVs, tablets, consumer electronics devices (ie: blu ray players with apps), and smartphones. Qualcomm expects to see devices powered by the new SoC become available sometime around the middle of 2013 (1H’13).

The new chips appear to offer up some noticeable performance and efficiency improvements over the current generation of Snapdragon processors. The Snapdragon 800 in particular is an impressive-sounding design. I am interested to see how it stacks up against competing chips such as NVIDIA’s Tegra 4, Samsung’s next-gen Exynos lineup, and whatever chip Apple has up its sleeve for the next iPad/iPhone refresh. This year is shaping up to be an exciting year for ARM-based SoCs!

If you are interested in the new silicon, Qualcomm has teased a few more details on its blog.

NVIDIA to rip the ARMs off of Surface?

Subject: General Tech | January 10, 2013 - 03:20 PM |
Tagged: microsoft, surface, winRT, tegra 4, nvidia, arm

NVIDIA's new Shield gaming device might have distracted your attention from another new product they demonstrated which could be even more important to their success, a fully functional WinRT tablet.  The tablet is powered by a Tegra 4 chip and apparently runs smoothly even on this OS which was theoretically designed for ARM hardware.  DigiTimes feels that this is a sign that NVIDIA, who have had a long if somewhat troubled relationship with Microsoft, could become a chip supplier for new Surface devices and tablets.  Hopefully in the near future we will get to see a head to head review of two devices powered by different chips so that we can see which provides the best experience.

"Nvidia unveiled a pilot tablet based on its new Tegra 4 processor and Microsoft's Windows RT operating system at CES 2013, and since the device is already operating smoothly, Nvidia will have a chance of becoming the CPU supplier for next-generation Surface tablets or Windows RT-based tablets from other IT players, according to Digitimes Research senior analyst Eric Lin."

CES 2013: Samsung Teases Eight Core Exynos Octa SoC

Subject: Mobile | January 10, 2013 - 06:29 AM |
Tagged: SoC, Samsung, exynos octa, exynos, ces 2013, CES, big.little, arm

Samsung talked up a new ARM SoC during CES that will become the new high-end part of its Exynos 5 lineup. The Samsung Exynos 5 Octa is, as the name suggests, an eight core processor. It is built on a 28nm manufacturing process and employs ARM's big.LITTLE architecture.

Samsung Exynos Octa.jpg

While Samsung is not ready to share all the detailed under-the-hood details, the Exynos 5 Octa has four Cortex A15 cores clocked at 1.8GHz paired with four Cortex A7 cores clocked at 1.2GHz. With big.LITTLE, the SoC has both high performance, high powr cores and lower power cores. The configuration is invisible to the end user, and the chip will use the Cortex A15 cores when in 3D applications or other CPU load intensive applications. Then, while the phone is idle or simply running background applications (notifications, checking email, updating twitter and facebook feeds, ect), the SoC will power down the Cortex A15 cores and use the lower power-drawing A7 cores. Ideally, this will give users a "best of both worlds" situation and a balance of performance and battery life.

Samsung claims that the Exynos 5 Octa offers up to twice the 3D performance of other existing current-generation SoCs. However, we do not yet have details on the GPU improvements (if any) over Samsung's other Exynos 5 chips much less benchmark-able products running this chip yet so it is difficult to say whether that statement is true or not. Also, Samsung claims as much as a 70% improvement in power savings over its dual core Exynos 5 processor, which is certainly a bold claim.

According to Engadget, Samsung plans to reveal all the nitty-gritty details on the eight-core Exynos 5 Octa SoC at the International Solid State Circuits Conference on February 19, 2013. It should give NVIDIA's "4+1" core Tegra 4 a run for its money, at lest on the CPU front (and maybe 3D graphics as well, but it's hard to say at this point).

CES 2013: NVIDIA Officially Releases Tegra 4 SoC

Subject: General Tech | January 7, 2013 - 03:01 AM |
Tagged: tegra 4, SoC, nvidia, cortex a15, ces 2013, CES, arm

Details about NVIDIA’s latest system on a chip (SoC) for mobile devices leaked last month. On Sunday, NVIDIA officially released its Tegra 4 chip, and talked up more details on the new silicon.

Interestingly, the leaked information from the slide held true over the weekend when NVIDIA officially unveiled it during a press conference. The new chip is manufactured on a 28nm, low power, high-k metal gate process.  It features four ARM Cortex-A15 CPU cores running at up to 1.9GHz, one (additional) low power Cortex-A15 companion core, a NVIDIA GeForce GPU with 72 cores (not unified shader design unfortunately). In addition, the Tegra 4 SoC includes the company’s i500 programmable soft modem, and a number of fixed function hardware used for audio and image processing.

According to Anandtech, the majority of GPU cores in the Tegra 4 are 20-bit pixel shaders though exact specifications on the GPU are still unknown. Further, the i500 modem currectly supports LTE UE Category 3 on the WCDMA band with an LTE 4 modem expected in the future.

Tegra 4 will support dual channel LP-DDR3 memory, USB 3.0, and a technology that NVIDIA is calling its Computational Photography Architecture that allegedly will allow real-time HDR imagery with still and video shoots.

According to NVIDIA, Tegra 4 will be noticeably faster than its predecessors and the competing SoCs from Apple and Qualcomm et al. When compared to the Nexus 10 (Samsung Exynos 5 SoC) and the stock Android web browser, the Tegra 4 device (Chrome browser) opened pages in 27 seconds versus the Nexus 10’s 50 second benchmark time. Users will have to wait for retail devices with Tegra 4 hardware for independent benchmarks, however. Thanks to the higher top-end clockspeed and beefier GPU, you can expect Tegra 4 to be faster than Tegra 3, but until reviewers get their hands on Tegra 4-powered devices it is difficult to say just how much faster it is.

Speaking of hardware, the Tegra 4 chip will most likely be used in tablets (and not smartphones). Here’s hoping we see some prototype Tegra 4 devices or product announcements later this week at CES.

Intel versus ARM; the hunting cry of a krayt dragon

Subject: Systems | January 4, 2013 - 07:59 PM |
Tagged: arm, Intel, krayt, atom, qualcomm, cortex a15, tegra 3

AnandTech managed to get their hands on an Samsung designed ARM Cortex A15 processor powered tablet, which they compared to several competitors such as Intel's Atom, Qualcomm's Krait and NVIDIA's Tegra 3.  The test names may seem unfamiliar with Sunspider, Kraken and RIABench providing performance comparisons though the power consumption tests will be familiar to all.  Read on to see how the next generation of chips from the main contenders for your mobile device spending compare.

GreaterKrayt-WOSW.jpg

"The previous article focused on an admittedly not too interesting comparison: Intel's Atom Z2760 (Clover Trail) versus NVIDIA's Tegra 3. After much pleading, Intel returned with two more tablets: a Dell XPS 10 using Qualcomm's APQ8060A SoC (dual-core 28nm Krait) and a Nexus 10 using Samsung's Exynos 5 Dual (dual-core 32nm Cortex A15). What was a walk in the park for Atom all of the sudden became much more challenging. Both of these SoCs are built on very modern, low power manufacturing processes and Intel no longer has a performance advantage compared to Exynos 5."

NVIDIA Tegra 4 Details Revealed By Leaked Slide

Subject: Processors, Mobile | December 19, 2012 - 03:26 AM |
Tagged: wayne, tegra 4, SoC, nvidia, cortex a15, arm

Earlier this year, NVIDIA showed off a roadmap for its Tegra line of mobile system on a chip (SoC) processors. Namely, the next generation Tegra 4 mobile chip is codenamed Wayne and will be the successor to the Tegra 3.

Tegra 4 will use a 28nm manufacturing process and feature improvements to the CPU, GPU, and IO components. Thanks to a leaked slide that appeared on Chip Hell, we now have more details on Tegra 4.

NVIDIA Tegra 4 Leaked Slide.jpg

The 28nm Tegra 4 SoC will keep the same 4+1 CPU design* as the Tegra 3, but it will use ARM Cortex A15 CPU cores instead of the Cortex A9 cores used in the current generation chips. NVIDIA is also improving the GPU portion, and Tegra 4 will reportedly feature a 72 core GPU based on a new architecture. Unfortunately, we do not have specifics on how that GPU is set up architecturally, but the leaked slide indicates that the GPU will be as much as 6x faster than NVIDIA’s own Tegra 3. It will allegedly be fast enough to power displays with resolutions from 1080p @ 120Hz to 4K (refresh rate unknown). Don’t expect to drive games at native 4K resolution, however it should run a tablet OS fine. Interestingly, NVIDIA has included hardware to hardware accelerate VP8 and H.264 video at up to 2560x1440 resolutions.

Additionally, Tegra 4 will feature support for dual channel DDR3L memory, USB 3.0 and hardware accelerated secuity options including HDCP, Secure Boot, and DRM which may make Tegra 4 an attractive option for Windows RT tablets.

The leaked slide has revealed several interesting details on Tegra 4, but it has also raised some questions on the nitty-gritty details. Also, there is no mention of the dual core variant of Tegra 4 – codenamed Grey – that is said to include an integrated Icera 4G LTE cellular modem. Here’s hoping more details surface at CES next month!

Intel Might Become a Foundry -- For ARM? If Apple Goes x86

Subject: General Tech, Processors, Mobile | December 4, 2012 - 07:28 PM |
Tagged: Intel, arm, apple

Hopefully I did not make your head hurt too much with that title.

Intel announced early in the year the opening of their fabrication labs to certain other developers, none of which competing with anything Intel does. We joked about how this is the end of the world as we know it although we feel fine. As it turns out, the world might end December 2012: RBC rumors that Intel might fulfill orders of ARM processors taking away that responsibility from Samsung.

Of course, there will always be a catch. It is possible that Intel will allow Apple to manufacture their ARM-based processors at Intel if Apple switches their tablets to x86-based products. No-one said the apocalypse must be an irrational event.

intel-cmon.png

When pigs fly? Challenge accepted.

If this rumor comes to fruition - and that is a mighty large if - we finally know that a line of apathy exists within Intel. Intel fabricating an architecture that they directly compete with is a big deal, ignore their motive.

Intel has allegedly made a compromise, definitively this time. We debated fairly heavily whether Intel made a compromise when they allowed FBGAs to be manufactured at their facilities. This time there is no question about whether Intel will make a concession to better its company as a whole.

I have no doubt that Intel desires to stomp competing platforms but we should all doubt that Intel would never step into some middle ground. After all, Intel is not even suffering at this point by any measure. Imagine if the situation actually begins to look dire.

The new strong ARM line up of X-Men from Applied Micro Circuits

Subject: General Tech | November 27, 2012 - 03:38 PM |
Tagged: arm, Applied Micro Circuits, X-Gene, X-Compute, X-Memory, X-Storage

There is more choice to put ARM power into your server room with three new products with varying roles.  The first is the X-Compute card with a single 8 core X-Gene processor and up to 128GB of memory, connectivity is three gigabit and one 10 gigabit ethernet ports. This they see running web apps and monitoring or load balancing purposes.  Next is the X-Memory machine with 16 cores thanks to two X-Gene chips and it can support up to 256GB of memory, its connectivity is a little more advanced with two 10 gigabit connections in addition to three gigabit connections.  Obviously this is intended for memory dependent applications which don't depend on high density local storage.  Last but certainly not least is the biggest member, the X-Storage which can handle up to 11 3.5" SATA drives and an additional three 2.5" SATA drives and sports a single eight X-Gene processor, up to 32GB of memory plus one gigabit and one 10 gigabit networking port.  The Register doesn't have benchmarks but you can see what these devices will look like right here.

ElReg_amcc_x_gene_xcompute_board.jpg

"Applied Micro Circuits is not yet shipping its first X-Gene ARM-based processor aimed at servers, and it is going to be a while yet before it can get the processors into the field. But because there is so much at stake, Applied Micro can't afford to be left out of any conversations about ARM Holding's attack on the data center. The reason? It has invested very heavily (at least relative to its size) in this X-Gene project."
