Intel Core i7 6800K Benchmarks On Ubuntu + Linux 4.8

Filed under
Graphics/Benchmarks

While the Core i7 6800K has been available for a few months now, there hadn't been any review on it since Intel hadn't sent out any Broadwell-E samples for Linux testing this time around. However, I did end up finally buying a Core i7 6800K now that the Turbo Boost Max 3.0 support is finally coming together (at first, Intel PR said it wouldn't even be supported on Linux) so that I can run some benchmarks there plus some other interesting items on the horizon for benchmarking. Here are some benchmarks of the i7-6800K from Ubuntu 16.04 LTS with the Linux 4.8 kernel.

  • The RADV Radeon Vulkan Linux Driver Continues Picking Up Features
  • OpenChrome Maintainer Making Some Progress On VIA DRM Driver

    Independent developer Kevin Brace took over maintaining the OpenChrome DDX driver earlier this year to improve the open-source VIA Linux graphics support while over the summer he's slowly been getting up to speed on development of the OpenChrome DRM driver.

    The OpenChrome DRM driver was making progress while James Simmons was developing it a few years back, but since he left the project, it's been left to bit rot. It will take a lot of work even to get this previously "good" code back to working on the latest Linux 4.x mainline kernels given how DRM core interfaces have evolved in recent times.

  • My talk about Mainline Explicit Fencing at XDC 2016!

    Last week I was at XDC in Helsinki where I presented about the Explicit Fencing work we’ve been doing on the Mainline Linux Kernel in the lastest few months. There was a livestream of all presentations during the conference and recorded sections are available. You can check the video of my presentation. Check out the slides too.

  • What’s New in Wayland and Weston 1.12?

    The Wayland core protocol documentation has received numerous refinements to improve its clarity and consistency. Along with this, many blank areas of the protocol documentation have been fleshed out.

    A new wl_display_add_protocol logger API provides a new, interactive way to debug requests; along with this are new APIs for examining clients and their resources. This is analogous to using WAYLAND_DEBUG=1, but more powerful since it allows run time review of log data such as through a UI view.

    There have been improvements to how the protocol XML scanner handles version identification in protocol headers. This enables better detection and fallback handling when compositors and clients support differt versions of their protocols.

  • 2D Rendering On X11 Remains Barely Faster Than CPU Rendering

    In addition to being the organizer of XDC2016, Martin Peres also participated in several presentations at this week's conference in Helsinki. One of these pesentations by Martin was concerning 2D X.Org acceleration.

    Martin basically presented on that rendering 2D on a modern X.Org Server is barely faster than CPU rendering, unless compositing. While being barely faster, it consumes more power than CPU-only rendering. But the good news is that more and more software is moving away from X-based rendering.

    With the next GTK+ release there will be the GTK Scene Kit, Qt5 already has changed its renderer, and other projects are moving over to purely CPU-based rendering or GPU rendering with projects like Servo's WebRender, Google's Skia, and the new Intel FastUIDraw project.

  • Don't Expect An Open-Source NVIDIA Vulkan Driver Anytime Soon
  • AMD's DAL Was Just Presented At XDC2016, Still Not Clear When It Will Be Mainlined

    Harry Wentland of AMD just presented at the XDC2016 conference about DAL, the big Display Abstraction Layer code-base, which many AMD Linux users have been waiting to see merged in order to have Polaris audio support and this is one of the stepping stones for seeing FreeSync/Adaptive-Sync and other modern display capabilities.

    We have been covering DAL for months since AMD open-sourced it and since then they've been trying to clean it up, remove some redundancies compared to what core DRM offers, etc. DAL is a big piece of the puzzle that's left for getting mainlined so the AMDGPU open-source kernel driver can be closer to feature parity with the closed-source driver and what's provided on Windows.

  • The Open-Source Intel Vulkan Linux Driver's Anatomy

    Intel Open-Source Technology Center developer Jason Ekstrand presented earlier today at XDC2016 with a presentation entitled "The Anatomy of a Vulkan Driver" where he covers how he and fellow Intel developers brought up the first open-source Vulkan driver and had it ready for launch-day when Khronos formally unveiled the specification earlier this year.

    The early part of the presentation will be boring to anyone who frequently reads Phoronix with the dozens of articles I've written since February concerning progress on the Intel Vulkan driver, Vulkan itself, etc. The early part of the presentation just provides a basic overview of what is Vulkan, the need for Vulkan, etc etc... But the latter half of the presentation is what's interesting when he talks more about the design decisions, how he and basically three Intel developers brought up this driver (along with the support of many other Intel developers), and other commentary surrounding the Intel Linux Vulkan driver's design.

    The latest stable release of the Nouveau X.Org driver is now available for users of this open-source NVIDIA DDX component in conjunction with the Nouveau DRM kernel driver.

    The xf86-video-nouveau 1.0.12 release happened nine months ago so there are some changes that came together in that tine, but then again the most interesting innovations in the open-source Linux graphics stack fall outside the DDX drivers the past few years. In total since the v1.0.12 release were just seven commits.

  • How Google's Android Runtime On Chrome OS Uses Wayland, DRM

    Google developer David Reveman presented at this morning's XDC2016 conference in Finland about the Android Runtime for Chrome making use of Wayland (ARC++) and how the rest of its graphics stack looks for running Android programs on Chrome OS.

    For rendering with ARC++, Gralloc and the OpenGL ES driver are using the Direct Rendering Manager, applications have full access to OpenGL ES, and there are support for other rendering APIs. Compositing with ARC++ is handled by the Android HWComposer and then surfaces are forwarded to Chrome for compositing with the rest of Chrome OS' user-interface.

  • Wayland 1.12 Next-Gen Linux Display Server Officially Released with Many Goodies

    Today, September 21, 2016, Bryce Harrington has had the great pleasure of announcing the immediate availability of the Wayland 1.12.0 display server for GNU/Linux operating systems, along with the Weston 1.12.0 compositor.

    Development for Wayland 1.12 and Weston 1.12 started exactly a month ago when the first Alpha build was seeded to public testers, and it already contained many of the new functionalities and improvements implemented in this final build we can install today on our GNU/Linux distributions.

  • New Open Source Linux Ransomware Divides Infosec Community

  • Fax machines' custom Linux allows dial-up hack
    Party like it's 1999, phreakers: a bug in Epson multifunction printer firmware creates a vector to networks that don't have their own Internet connection. The exploit requirements are that an attacker can trick the victim into installing malicious firmware, and that the victim is using the device's fax line. The firmware is custom Linux, giving the printers a familiar networking environment for bad actors looking to exploit the fax line as an attack vector. Once they're in that ancient environment, it's possible to then move onto the network to which the the printer's connected. Yves-Noel Weweler, Ralf Spenneberg and Hendrik Schwartke of Open Source Training in Germany discovered the bug, which occurs because Epson WorkForce multifunction printers don't demand signed firmware images.
  • Google just saved the journalist who was hit by a 'record' cyberattack
    Google just stepped in with its massive server infrastructure to run interference for journalist Brian Krebs. Last week, Krebs' site, Krebs On Security, was hit by a massive distributed denial-of-service (DDoS) attack that took it offline, the likes of which was a "record" that was nearly double the traffic his host Akamai had previously seen in cyberattacks. Now just days later, Krebs is back online behind the protection of Google, which offers a little-known program called Project Shield to help protect independent journalists and activists' websites from censorship. And in the case of Krebs, the DDoS attack was certainly that: The attempt to take his site down was in response to his recent reporting on a website called vDOS, a service allegedly created by two Israeli men that would carry out cyberattacks on behalf of paying customers.
  • Krebs DDoS aftermath: industry in shock at size, depth and complexity of attack
    “This attack didn’t stop, it came in wave after wave, hundreds of millions of packets per second,” says Josh Shaul, Akamai’s vice president of product management, when Techworld spoke to him. “This was different from anything we’ve ever seen before in our history of DDoS attacks. They hit our systems pretty hard.” Clearly still a bit stunned, Shaul describes the Krebs DDoS as unprecedented. Unlike previous large DDoS attacks such as the infamous one carried out on cyber-campaign group Spamhaus in 2013, this one did not use fancy amplification or reflection to muster its traffic. It was straight packet assault from the old school.
  • iOS 10 makes it easier to crack iPhone back-ups, says security firm
    INSECURITY FIRM Elcomsoft has measured the security of iOS 10 and found that the software is easier to hack than ever before. Elcomsoft is not doing Apple any favours here. The fruity firm has just launched the iPhone 7, which has as many problems as it has good things. Of course, there are no circumstances when vulnerable software is a good thing, but when you have just launched that version of the software, it is really bad timing. Don't hate the player, though, as this is what Elcomsoft, and what Apple, are supposed to be doing right. "We discovered a major security flaw in the iOS 10 back-up protection mechanism. This security flaw allowed us to develop a new attack that is able to bypass certain security checks when enumerating passwords protecting local (iTunes) back-ups made by iOS 10 devices," said Elcomsoft's Oleg Afonin in a blog post.
  • After Tesla: why cybersecurity is central to the car industry's future
    The news that a Tesla car was hacked from 12 miles away tells us that the explosive growth in automotive connectivity may be rapidly outpacing automotive security. This story is illustrative of two persistent problems afflicting many connected industries: the continuing proliferation of vulnerabilities in new software, and the misguided view that cybersecurity is separate from concept, design, engineering and production. This leads to a ‘fire brigade approach’ to cybersecurity where security is not baked in at the design stage for either hardware or software but added in after vulnerabilities are discovered by cybersecurity specialists once the product is already on the market.

Ofcom blesses Linux-powered, open source DIY radio ‘revolution’

Small scale DAB radio was (quite literally) conceived in an Ofcom engineer’s garden shed in Brighton, on a Raspberry Pi, running a full open source stack, in his spare time. Four years later, Ofcom has given the thumbs up to small scale DAB after concluding that trials in 10 UK cities were judged to be a hit. We gave you an exclusive glimpse into the trials last year, where you could compare the specialised proprietary encoders with the Raspberry Pi-powered encoders. “We believe that there is a significant level of demand from smaller radio stations for small scale DAB, and that a wider roll-out of additional small scale services into more geographic areas would be both technically possible and commercially sustainable,” notes Ofcom.
