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 […]

What to Expect from AllWinner, Rockchip, Mediatek, and Other Silicon Vendors at CES 2014

CES 2014 is coming soon, and it will take place on 7 – 10 January, 2014, and we can expect some interesting SoC news. Samsung suggested they will unveil their 64-bit ARM SoC (Exynos 6?) at CES 2014, Nvidia will hold a press conference to “showcase new NVIDIA Tegra mobile technologies, gaming innovations, and advanced automotive display technologies”, and Qualcomm has been quiet for now. However, several Chinese SoC vendors, namely AllWinner, Rockchip, and Mediatek, have already announced what they will showcase at CES 2014, albeit with few details. AllWinner at CES 2014 Allwinner announced will showcase their OptimusBoard based on their Ultra Octa-Core A80 SoC, as well as 4G tablets powered by Allwinner A31/A31s, and dual-SIM phablets sporting A23 dual-core. Allwinner A80 is an Octacore processor featuring four ARM Cortex A7 cores, and four Cortex A15 cores @ 2.0GHz together with an unnamed GPU offering 2x more performance over previous […]

NVIDIA Releases Source Code, Binaries, and Android Build Instructions for the SHIELD Gaming Console

This morning I’ve read bad news for the open source community. Jean-Baptiste Quéru, leader of the Android Open Source Project (AOSP) has decided to quit the project because AOSP cannot run on the latest Nexus 7 as Qualcomm (lawyers) impeded the project, and Google is unable to released factory images or necessary binary drivers for the GPU. But there’s also good news, as Nvidia has just released source code and binaries to allow developers to fully build an Android image for its SHIELD gaming console. If you want to build an image for the latest image available, following the steps below. Get the code

mkdir ~/shield-open-source
cd ~/shield-open-source
repo init -u git://nv-tegra.nvidia.com/manifest/android/binary.git -b rel-roth-ota-1-partner -m secureos/jb_roth.xml
repo sync -j5

mkdir ~/shield-open-source

cd ~/shield-open-source

repo init -u git://nv-tegra.nvidia.com/manifest/android/binary.git -b rel-roth-ota-1-partner -m secureos/jb_roth.xml

repo sync -j5

Build the Android image (Provided you’ve already setup your Linux PC do build AOSP):

cd ~/shield-open-source
export TOP=`pwd`
cd vendor/nvidia/licensed-binaries
./extract-nv-bins.sh
cd $TOP
. build/envsetup.sh
setpaths
lunch thor-userdebug
mp dev

cd ~/shield-open-source

export TOP=`pwd`

cd vendor/nvidia/licensed-binaries

./extract-nv-bins.sh

cd $TOP

. build/envsetup.sh

setpaths

lunch thor-userdebug

mp dev

Done (mp dev took about one hour for my machine). You should now have the required binary images in out/target/product/roth/ directory. Enter fastboot mode before flashing the binaries by one […]

Qualcomm Snapdragon 800 MDP Benchmarks

A few days ago, I saw some benchmark results showing Xiaomi M3 smartphone powered by Snapdragon 800 SoC getting a ridiculous score above 80,000 points in Antutu, but thought it was really odd, and it turned out to be a fake Antutu screenshot. The actual scores for Snapdragon 800, are much lower, yet one of the fastest mobile platform ever, according to benchmarks performed by Engadget, which hold of Qualcomm Snapdragon 800 Tablet and Smartphone MDPs. Engadget provided comparison of the benchmark for 12 devices, but I selected the 4 most powerful of the lot in the table below. S800 MDP tablet (MSM8974) S800 MDP phone (MSM8974) Samsung Galaxy S4 (Exynos 5 Octa) Nvidia Tegra 4 ref device Quadrant 2.0 20762 22022 13326 16436 Vellamo 2.0 2997 2914 1977 N/A AnTuTu 3.x 35783 33828 28167 36305 SunSpider 0.9.1 (ms) 543 566 732 499 SunSpider 1.0 (ms) 657 674 N/A N/A […]

Vivante GC4000 is The Best Mobile GPU… When It Comes to Accuracy

Most of the time, mobile GPU comparisons involve benchmarks such as Antutu, Nenamark 2, etc…, or people may consider which games will be able to run smoothly with a particular device, but we seldom compare image quality, for the simple reason it’s usually more difficult to achieve. YOUi Labs has just done that, however, by running the shader code below on several hardware platforms, mainly Android tablets, with the most common mobile GPUs, and used the results obtained with a Desktop PC GPU, Nvidia Geforce GT 630M, has a reference.

precision highp float;
uniform vec2 resolution;
void main( void )
{
      float x = ( 1.0 – ( gl_FragCoord.x / resolution.x ));

      float y = ( gl_FragCoord.y / resolution.y ) * 26.0;
      float yp = pow( 2.0, floor(y) );
      float fade = fract( yp + fract(x) );
      if(fract(y) &lt; 0.9)
          gl_FragColor = vec4( vec3( fade ), 1.0 );
    else
          gl_FragColor = vec4( 0.0 );
}

precision highp float;

uniform vec2 resolution;

void main( void )

{

float x = ( 1.0 – ( gl_FragCoord.x / resolution.x ));

float y = ( gl_FragCoord.y / resolution.y ) * 26.0;

float yp = pow( 2.0, floor(y) );

float fade = fract( yp + fract(x) );

if(fract(y) < 0.9)

gl_FragColor = vec4( vec3( fade ), 1.0 );

else

gl_FragColor = vec4( 0.0 );

}

Here are the results: The worst GPUs are Mali-400 MP4 in Exynos 4412 and Geforce ULP in Tegra 3, which can respectively only show 5 and 8 lines before degradation, and the top two GPUs are Qualcomm Adreno 225 in MSM8660A, and Vivante GC4000 in HiSilicon K3V2 processor. Imagination Technologies SGX544 and ARM Mali-T604 also provide decent results, but […]

Linux 3.9 Release

Linus Torvalds has announced the release of Linux Kernel 3.9: So the last week was much quieter than the preceding ones, which makes me suspect that one reason -rc7 was bigger than I liked was that people were gaming the system and had timed some of their pull requests for just before the release, explaining why -rc7 was big enough that I didn’t actually want to do a final release last week. Please don’t do that. Anyway. Whatever the reason, this week has been very quiet, which makes me much more comfortable doing the final 3.9 release, so I guess the last -rc8 ended up working. Because not only aren’t there very many commits here, even the ones that made it really are tiny and not pretty obscure and not very interesting. Also, this obviously means that the merge window is open. I won’t be merging anything today, but if […]
