Nvidia Announces Tegra X1 64-bit Octa-core Processor with 256-Core Maxwell GPU

CES 2015 has started, and the first company to present their innovations is Nvidia. Last year their introduced Tegra K1, the first mobile processor with a desktop GPU with support for OpenGL. They’ve now raised the bar with Tegra X1, an octa-core 64-bit ARM processor with a 256-core Maxwell GPU delivering 1.5x to 2x the performance of Tegra K1, and supporting 4K60 video playaback with H.265 and VP9 codecs. Some geekbench benchmark comparing X1, K1, and Apple A8x. Nvidia CEO also claiemd Tegra X1 is the first mobie SoC delivering over 1 Teraflops, something that was achieved around year 2,000 with 20,000 Pentium pro processor consuming 1 millions Watts, while X1 SoC only consumes about 10 Watts. Power efficiency is said to have improved too, as Maxwell GPU is said to delivers more performance with similar power efficiency. They also introduced Drive CX mini computer for automotive application featuring Tegra […]

Linux 3.17 Released

Linus Torvalds announced the release of Linux Kernel 3.17 on Sunday: So the past week was fairly calm, and so I have no qualms about releasing 3.17 on the normal schedule (as opposed to the optimistic “maybe I can release it one week early” schedule that was not to be). However, I now have travel coming up – something I hoped to avoid when I was hoping for releasing early. Which means that while 3.17 is out, I’m not going to be merging stuff very actively next week, and the week after that is LinuxCon EU… What that means is that depending on how you want to see it, the 3.18 merge window will either be three weeks, or alternatively just have a rather slow start. I don’t mind getting pull requests starting now (in fact, I have a couple already pending in my inbox), but I likely won’t start processing […]

More Technical Details & Benchmarks about Nvidia Tegra K1 “Denver” 64-bit ARM SoC

The 32-bit version of Nvidia Tegra K1 have generally received good reviews in terms of performance, especially GPU performance, and the company has also provided good developer’s documentation and Linux support, including open source drivers for the Kepler GPU (GK20A) found in the SoC. But as initially announced, Tegra K1 with also get a 64-bit ARM version codenamed “Denver”, and Nvidia provided more details at Hotchips conference. The 64-bit Tegra K1 will still feature a 192-core Kepler GPU, but replace the four ARM Cortex A15 cores found in the 32-bit version, by two ARMv8 “Project Denver” cores custom-designed by Nvidia. The multi-core performance of the dual core 64-bit Tegra K1 @ 2.5 GHz may end up being equivalent to the quad core 32-bit Tegra K1 @ 2.1 GHz, but the single core performance will be much better thanks to a a 7-way superscalar microarchitecture (vs 3-way for Cortex A15), as […]

Some Projects on Nvidia Jetson TK1 Development Board: Nintendo Emulator, USB3 Webcam, and Robotics

Nvidia Jetson TK1 is a development board powered by the company’s Tegra K1 quado core Cortex A15 processor, and especially a Kepler GPU that allows for OpenGL 4.4. It has shipped to developers around April/May, and some of them have showcased their projects, or tested some hardware. Dolphin Emulator on Nvidia Jetson TK1 Dolphin is an emulator for Nintendo GameCube and Wii console that supports full HD (1080p) rendering, and run on Android, Linux and Mac OS, and there’s also an Alpha version for Android. Ryan Houdek (Sonicadvance1), one of Dolphin’s developers, has leveraged Kepler’s OpenGL support via Nvidia’s GPU drivers, to port the emulator to the platform running on Ubuntu, but it should work as well on Tegra K1 hardware running Android such as XiaoMi MiiPad tablet. You can watch Mario Kart: Double Dash demo running at full speed on the Nvidia board below. According to the developer, such […]

Google Formally Launches Android TV. Android TV Set-Top Boxes and TVs to be Available in H2 2014

After Android L for mobile devices, and Android Wear for wearables, Google also announced Android for your television at Google I/O 2014, and after definitely killing “Google TV”, renaming it to “Google Services for Smart TV”, the company went for the obvious and called it “Android TV”, which will get messy with all the Chinese “Android TV” boxes that do not run “Android TV” but simply “Android”… Google apparently used an Android TV reference platform (ADT-1) based on Nvidia Tegra 4 K1 at I/O to showcase their latest implementation of Android the the living room. I’ve embedded the video of the demo below, but the key part of the demo can be summarized as follows: Android TV’s “TV Input Framework” can overlay notifications and other data on top of various video sources such as HDMI, TV tuners, and IP TV receivers Voice control demo (with smartphone) with requests such as: […]

HTC / Google Nexus 9 To Feature Nvidia Tegra K1 Dual Core 64-bit ARMv8 Processor

ARMv8 (64-bit ARM) architecture has been seen in servers, and announced in mobile SoCs, but, putting aside some Apple products, we have yet to see any consumer products based on the latest ARM architecture. But this will change soon, as HTC Volantis, which could become Google Nexus 9 based on the picture leaked via Android Police, will feature an “Nvidia Logan 64-bit” SoC, which can only be a Tegra K1 dual core ARMv8 SoC announced at CES 2014. HTC Volantis / Nexus 9 specifications: SoC – NVIDIA Tegra K1 (logan) dual core 64-bit Processor System Memory – 2GB RAM Storage – 16/32GB internal storage Display – 8.9″ Display at 2048×1440 (281ppi) Camera – 8MP main camera with OIS, 3MP front facing camera Audio – Stereo front-facing speakers Dimensions – 22.63×15.19×0.79cm Weight – 418g, or 427g with LTE The assumption is that it will be released as the latest major release […]
