TI Dual Core OMAP 5 Cortex A15 (800 Mhz) Twice as Fast as Nvidia Tegra 3 Quad Core Cortex A9 (1.3 Ghz)

Texas Instruments released a video showing the Web page loading time between TI OMAP 5 featuring two ARM Cortex-A15 cores at 800MHz (as well as specialized cores and accelerators), compared to a commercial device powered by a quad-core ARM Cortex-A9 processor at 1.3 GHz. They did not say it, but it’s got to be the Nvidia Tegra 3 since this is the only ARM Cortex A9 Quad-core processor with products available on the market today. In this  benchmark, the devices handle 3 tasks simultaneously: Rendering 20 web pages Downloading videos Play a MP3 file The result is quite amazing, even hard to believe, with the OMAP 5 rendering the 20 pages in 95 seconds whereas it took the NVidia Tegra 3 over 200 seconds. I’m sure we’ll get an explanation of this performance difference at MWC 2012.

Microsoft Provides Windows 8 On ARM Technical Details

Steven Sinofsky, President of the Windows Division at Microsoft, has written a long blog post entitled “Building Windows for the ARM processor architecture” where he explains how Windows On ARM (WOA) will be deployed, the steps they took to develop it and what developers can do to program or port existing apps to Windows 8. Here are some keys and interesting points I noted: WOA and Windows 8 for x86/64 PCs will ship at the same time and the user experience should be the same for consumers on both platform. WOA PCs will be powered by Texas Instruments, Nvidia and Qualcomm processors. Microsoft will release an Unified OS Binary for WOA – That means one binary will run on all platforms (be it TI, Nvidia or Qualcomm). That seems impressive, and something Linux is not capable of, although much work is done on that and a unified linux kernel should be available in 2014/2015.   To be fair, Linux has to …

Nvidia Announces CARMA Tegra 3 CUDA Development Kit

Nvidia has just unveiled its Tegra 3 development kit, the Nvidia CARMA. The development kit codename has been crowdsourced as Nvidia asked its followers to propose a name and vote for the best name. This development kit particularly targets CUDA, Nvidia parallel computing platform and programming model that enables dramatic increases in computing performance by harnessing the power of the graphics processing unit (GPU). The CARMA hardware has been designed by Seco and features an NVIDIA Tegra 3 ARM Cortex A9 Quad-Core CPU and NVIDIA CUDA GPU QuatroTM. Here are the technical specs for the development kit: CPU NVIDIA Tegra 3 Quad-Core ARM A9 GPU NVIDIA QuadroTM 1000M with 96 CUDA Cores Memory • CPU Memory: 2 GB • GPU Memory: 2 GB Peak Performance 270 Single Precision GFlops CPU – GPU Interface PCIe x4 Gen1 link Network 1x Gigabit Ethernet Storage 1x SATA Connector USB 3x USB 2.0 Display HDMI and DisplayPort Software • Linux Ubuntu Derivative OS • …

OMG! Quad Core Nvidia Tegra 3 Has Actually 5 Cores

We’ve been deceived ! All along we thought the new quad-core Nvidia Tegra 3 (codename Kal-El) would just have 4 cores…right… But Nvidia has just posted a blog entry talking about a mysterious fifth core. There is also the 12-core GPU, but we already knew about that. Here’s what Nvidia has to say about the fifth core: This extra core – which we call the “companion core” – runs at a lower frequency and operates at exceptionally low power. During less power-hungry tasks like web reading, music playback and video playback, Kal-El completely powers down its four performance-tuned cores and instead uses its fifth companion core. For higher performance tasks, Kal-El disables its companion core and turns on its four performance cores, one at a time, as the work load increases. The Variable SMP architecture is also completely OS transparent, which means that operating systems and applications don’t need to be redesigned to take advantage of the fifth core. That …

OpenCL (Open Computing Language) Overview and SDKs

OpenCL (Open Computing Language) is a multi-vendor open standard for general-purpose parallel  programming of heterogeneous systems that include CPUs, GPUs and other processors. OpenCL provides a uniform programming environment for software developers to write efficient, portable code for highperformance compute servers, desktop computer systems and handheld devices. OpenCL standard is managed and defined by the Khronos Group. The latest version (OpenCL 1.1) was ratified by the Khronos Group on the 14th of June 2010 and adds significant functionality for enhanced parallel programming flexibility, functionality and performance including: Host-thread safety, enabling OpenCL commands to be enqueued from multiple host threads. Sub-buffer objects to distribute regions of a buffer across multiple OpenCL devices. User events to enable enqueued OpenCL commands to wait on external events. Event callbacks that can be used to enqueue new OpenCL commands based on event state changes in a non-blocking manner. 3-component vector data types. Global work-offset which enable kernels to operate on different portions of the NDRange. …

Window 8 ARM Platforms at Build Conference 2011

Yesterday, I mentioned the Nvidia Tegra 3 tablet running Windows 8 which is currently showcased at Build Conference 2011 and they also had a Tegra 3 laptop running Windows 8. But Nvidia was not the only company showing off ARM based processors running Windows 8. There were at least 2 other companies, namely Qualcomm and Texas Instruments. Qualcomm showcased a Snapdragon MSM8660 (Dual core 1.2 GHz) Tablet running Windows 8 and announced that the first batch of Windows 8 PC will be based on the Snapdragon processor. Texas Instruments brought a Windows 8 Tablet based on OMAP4430 (dual core 1 GHz) developed in partnership with Quanta.

Microsoft demoes Windows 8 on Tegra 3 Tablet

Microsoft demonstrated several Windows 8 features running on a quad-core NVIDIA Tegra 3 tablet at the company’s BUILD developer conference in Anaheim, California. During the event, Mike Angulio – Microsoft’s VP of Windows planning – demonstrated: Windows 8 devices’ ability to instantly switch on and off The new Windows 8 user interface, designed to work equally well with both touch-based tablets and keyboard/mouse-based PCs New applications, mostly written in HTML5, which are always running in the background Platform agnostic applications (running on both ARM and x86) Anguilo also emphasized that all Windows 8 applications will feature hardware accelerated graphics so that developers will not need to do additional work to support hardware acceleration and their applications will automatically take advantage of graphics on both ARM and x86 platforms.

Nvidia Tegra 3 based Tablets Could be Ready for Xmas

Back in February at MWC2011, Nvidia announced its Tegra Roadmap including a demo of the Tegra 3 quad-core processor (Codenamed “Kal-El”) . Kal-El features a new Geforce GPU with 12 cores, giving 5 times greater performance than Tegra 2 and  NVidia also provided benchmark results showing that Kal-El was faster than an Intel Core2 Duo T7200. Yesterday, NVidia CEO – Jen-Hsun Huang – announced that tablets based on Nvidia Tegra 3 could be available later this year, but that quad-core smartphones would only be available in 2012. Since Android 4.0 is likely to be released sometimes in October or November, we could see quad-core Android 4.0 tablet for Xmas although the schedule is very tight. He went on to say that there are only 2 active players in the high-end mobile processor market: Nvidia and Qualcomm  (Qualcomm will ship its latest quad-core processor Snapdragon APQ8064 later in 2012). Nvidia CEO claimed that Tegra chips are already installed in half of …
