Intel Bay Trail Graphics Overview – FOSDEM 2014

Bay Trail SoCs are new low power Intel ICs for tablets (Bay Trail-T, Z3000 series), mobiles (Bay Trail-M, N2800, N2900 and N3500 series), desktops (Bay Trail-D, J1800, J1900 and J2900 series) and embedded / industrial platforms (Bay Trail-I, E3800 series). Many Atom processors used to features PowerVR GPU, but it has now been replaced by Intel HD graphics in Bay Trail SoC. Jesse Barnes, working at Intel on software and drivers for Intel graphics devices, gives a presentation about Bay Trail SoCs with a focus on graphics. After an overview, and some ARM bashing regarding performance (Nvidia Tegra 4 and Qualcomm Snapdragon 800), and even power consumption (Tegra 4 only), he describe further details about Intel HD graphics found in the new Intel processors. Everything is basically in mainline, and you’ll need Linux 3.10 or greater, Mesa 9.2 or greater, and libva 1.2.1 or greater for proper support. Some initial […]

ARM Unveils Cortex A17 Processor, First Used in Mediatek MT6595 and Rockchip RK3288 SoCs

Finally all these ARM Cortex A17 marketing materials for Rockchip RK3288 were not some typos, but Rockchip marketing team may just have not received the memo reading “Confidential”, as ARM has now officially announced Cortex A17 processor based on ARMv7-A architecture, with support for big.LITTLE with Cortex A7, and that can be coupled with Mali-T720 mid-range GPU and Mali-V500 VPU. After Cortex A15, and Cortex A12, you may wonder “Why? But Why did ARM had to launch yet another new core?”. Here’s the company answer to that question: The Cortex-A17 processor offers 60% performance uplift over the Cortex-A9 processor, the current leader in mid-range mobile market, and betters the best efficiency enabling optimized solutions to address existing and new products. The Cortex-A17 processor is based on the popular ARMv7-A architecture, today’s most successful architecture in the mobile market. With over 1M apps supporting the ARMv7-A architecture, the Cortex-A17 processor is […]

ARM Mali GPU Demos at CES 2014 – 4K 3D UI and Games, ASTC Texture Compression, XBMC + Gesture Recognition, and HEVC Video Decoding

Phill Smith, Demo Manager at ARM, has filmed and uploaded four very interesting demos of what new features will be possible thanks to new generation ARM Mali-450 and Mali-T6xx GPUs including 4K 3D user interfaces and games, ASTC texture compression, and OpenCL accelerated gesture recognition and HEVC / H.265 video decoding. 4K Resolution 3D User Interface and Game Demo The first demo showcases a Geniatech box (ATV1800?) powered by AMLogic AML8726-M8 featuring an ARM Mali-450MP6 GPU running Android with a user 4K 3D interface designed by Autodesk using Scaleform UI. The rest of the video shows Timbuku 3D gaming demo running at 3840×2160 (4K2K) @ 24 fps. The frame rate appears to be low, but that’s because the box is using HDMI 1.4, which limits UHD output to 24fps. 2160p60 is only available via HDMI 2.0. ASTC Compression Demo on Samsung Galaxy Note 3 3D Textures are getting bigger and […]

Linux Kernel 3.13 Release

Linus Torvalds announced the release of Linux Kernel 3.13 yesterday: The release got delayed by a week due to travels, but I suspect that’s just as well. We had a few fixes come in, and while it wasn’t a lot, I think we’re better off for it. At least I hope so – I’ll be very disappointed if any of them cause more problems than they fix.. Anyway, the patch from rc8 is fairly small, with mainly some small arch updates (arm, mips, powerpc, s390, sparc, x86 all had some minor changes, some of them due to a networking fix for the bpf jit). And drivers (mainly gpu and networking). And some generic networking fixes. The appended shortlog gives more details. Anyway, with this, the merge window for 3.14 is obviously open. Kernel 3.12 brought new features to BTRFS and XFS file systems, PC’s GPU drivers improvements, better memory handling, […]

Tegra K1 based Devices Could be Just as Fast as Mid Range Intel Core i5 Laptops

Some benchmark results comparing Nvidia Tegra K1 reference tablet to Intel based laptops show the latest ARM SoC matches and even outperforms many Intel devices, at least when it comes to 3D performance thanks to the 192-core Kepler GPU found in Tegra K1. In T-Rex HD Offscreen test in GFXBench 2.7.5, Tegra K1 is hown to be about 4 times faster than Tegra 4, over twice as fast as Qualcomm Snapdragon 800, and interestingly it outperforms some Intel laptop such as Acer Aspire V5-573G powered by an Intel Core i5 4200U processor with HD Graphics 4200 GPU. It’s still twice as slow as a machine with an Intel Core i7-4000MQ and Geforce GT 740M. CPU performance will probably be equivalent to some Intel Core i3 machine however, at least for the quad core ARM Cortex 15 version, but that still probably means it’s very likely we’ll find computers and laptops […]

Imagination Unveils OpenGL ES 3.0 Compliant Entry Level PowerVR Series6XE GPUs, and Series6XT Architecture Promising TFLOPS Performance

Imagination Technologies has announced four OpenGL ES 3.0 compliant mobile GPUs based on PowerVR Series6XE Rogue architecture for entry level ($100) smartphones, tablets, and other low-end consumer devices such as wearables and smart TVs, as well as four high-end GPUs based on PowerVR Series6XT Rogue architecture capable of TeraFLOPS computing power. PowerVR Series6XE GPUs The new PowerVR Rogue GPUs will deliver the same fillrate performance as equivalent Series5XT multi-processor configurations but offer more in terms of features and functionality, including OpenGL ES 3.0, OpenCL 1.x, and DirectX 9.3. Four entry-level GPUs have been introduced at CES 2014: PowerVR G6050 – Smallest fully-featured GPU core by Imagination with support for OpenGL ES3.0 and OpenCL 1.x. PowerVR G6060 – Same as G6050, but adds PVRIC2, the company’s second generation lossless PowerVR Image Compression. It reduces bandwidth requirements, and it likely to be used in entry-level tablets, HD TVs and STBs. PowerVR G6100 […]

NVidia Announces Tegra K1 32-bit & 64-bit SoCs with a 192 Core Kepler GPU

Nvidia announced their newest mobile SoC at CES 2014, but instead of calling it Tegra 5, they went for Tegra K1, as it’s the first to feature a 192 cores GPU based on Kepler architecture, the same as used in PC graphics card. There will be several version of the chip one based on four Cortex A15 cores, one featuring a dual core Nvidia Denver CPU based on ARMv8 64-bit architecture, and Tegra K1 VCM for the automotive market. The company showcased the power of their new processor with an Unreal Engine 4 demo and the same face demo showed last year on an Nvidia GPU card, and Tegra K1 easily outperform older generations games console such as Xbox 360 and PlayStation 3, at and the same time consume just about 5 Watts of power, versus 100 Watts for Microsoft and Sony consoles. The GPU in the Tegra K1 also […]
