Nvidia SHIELD TV Benchmarks in Ubuntu Shows Core i3 Like Performance

Nvidia SHIELD Android TV was announced this March with Nvidia Tegra X1 octa-core Cortex A57 + A53 processor. So far, I had not seen any Ubuntu or other Linux distribution port, but Michael Mirabel of Phoronix got remote access to a Shield TV PRO – model with a 500GB hard drive – running Ubuntu 14.10. It’s not clear who provided access, either Nvidia or third parties, but somebody posted an Ubuntu 14.10 port on XDA Developers Forums recently so it might be that one. He obviously ran Phoronix Test Suite on the device, and compared to it some other ARM devices (Compule Utilite, Jetson TK1), MIPS Creator CI20, low power x86 devices (Compute Stick, Intel NUC with Celeron N2820), and an Intel Core i3-5010u NUC. The Tegra X1 platform easily beats all other low power platforms, and comes close to the Core i3 mini PC in most tests. In the […]

Tegra X1 Chromebooks Likely in the Works

When Nvidia announced Tegra X1 processor, the company’s main focus appeared to be the automotive market as it introduced Drive PX and CX board for this very market. Since then, Tegra X1 based SHIELD console was unveiled, and I’ve been informed some development activity related to Tegra X1 (Model: Tegra210 / T210) was taking place in Chromium and especially Coreboot source code. There appears to be two hardware platforms based on Tegra X1: smaug and foster which could end-up being Chromebooks or Chromeboxes likely with 4GB RAM. Thanks to David for the information.

Nvidia Unveils $199 SHIELD Android TV Game Console Powered by Nvidia Tegra X1 Processor

Can it run Crisis? Yes! Nvidia has just announced SHIELD, an Android TV Game Console powered by the latest Tegra X1 SoC coupled with 3GB, 16GB flash, and which I believe to be the very first consumer ARM system with true 4K video output, decoding/encoding up to 60 fps, as well as both VP9 and H.265 codec at 4K resolution. I’m still not 100% sure gaming will be feasible at 4K resolutions. Since they already have a Shield tablet, and Shield portable game console, it would have been nice to find another name though… SHIELD specifications: SoC – NVIDIA Tegra X1 octa-core processor with 4x Cortex A57 cores, 4x Cortex A53 cores, and a 256-core Maxwell GPU System Memory – 3GB RAM Storage – 16 GB + MicroSD slot Video Output – HDMI 2.0 up to 4K @ 60 Hz Video – 4K playback and capture up to 60 fps […]

Nvidia Tegra X1 Gets About 75,000 Points in Antutu

Nvidia Tegra X1 was expected to outperform the competition, but based on Antutu results provided by Mydrivers, the performance leap might be greater than expected, as Nvidia Tegra X1 reference tablet gets 74,997 points in Antutu 5.6.1. As usual caution is warranted with Antutu results, as the benchmark is easily cheated, which explains why Allwinner A80T devices can get over 140,000 points. But let’s assume Tegra X1 result is representative and compare it to its predecessor the Tegra K1. Surprisingly I struggled to find a detailed Antutu 5.x score for the Nexus 9, and I had to get the scores from that video with Antutu 5.2.0. Nexus 9 (Tegra K1 64-bit) Tegra X1 Reference Platform Ratio Antutu 57040 74977 1.31x Multitask 11817 9217 0.78x Runtime 4146 4758 1.15x CPU integer 3038 11295 3.72x CPU float-point 1939 7274 3.75x Single-thread integer 2920 3206 1.10x Single-thread float-point 2831 2878 1.02x RAM operations […]

Patchsets for Nvidia Tegra K1 “Denver” Submitted to Linux Mainline

Some patchsets have been submitted for Nvidia Tegra 132 a few days ago to the Linux ARM Kernel mailing list. Tegra 132 is the codename for the 64-bit version of Tegra K1, and they’re also a mention of Norrin64 FFD board, that should be a Chromebook reference design.

Tegra114 and Tegra124 are the codename for Tegra K1 32-bit processor with Tegra124 clocked at a higher frequency. Norrin64 board dts does not seem included in the patchsets, but it’s available from Chromium OS code, and shows it’s using 2GB RAM too. That also means Chrombooks like Acer Chromebook 13 (CB5) or HP Chromebook 14 with the 32-bit version of the Tegra K1 might soon get an upgrade to the 64-bit version. Thanks to David for the tip.

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 […]
