Once upon a time Intel manufactured mobile processors for smartphones and tablets, but they eventually gave up as their solutions failed to gain traction. However, it looks like they may be back, as one customers required them to developer a chip with higher performance than Atom processors combined with a 2 mW standby power state. The chip was developed using “Foveros” 3D stacking technology was showcased at Intel’s Architecture Day 2018, but before going into further details, let’s have a look at Atom and Core processors roadmap to 2023 unveiled at the event. First, Intel will have developed three new Atom micro-architectures going into 2023. As we’ve seen previously, Tremont will succeed Goldmont Plus microarchitecture found in Gemini Lake and Denverton processors, and improve single-threaded performance, network server performance, and battery life starting in 2019. Around 2021, Gracemont will be launched with again higher single-thread performance and frequency, as well […]
ASUS ZenBook Pro 14 UX480FD Laptop Replaces the Touchpad with a 5.5″ “ScreenPad” Display
Touchpads is a feature found in most laptops, but AFAIK there’s not been much innovation recently apart from maybe support for multitouch and gestures. But I’ve just found out ASUS started to showcase laptops without touchpad a few months ago, instead integrating what the company calls a ScreenPad, a 5.5″ touchscreen display placed at the location where you’d normally expect a touchpad. The company’s latest (and second) laptop with a ScreenPad is Asus ZenBook Pro 14 UX480FD, which comes with a 14″ display, processor up to an Intel Core i7-8565U Whiskey Lake-U processor, up to 16GB DDR4 RAM, and up to 1TB PCIe SSD storage, as well as an NVIDIA GeForce GTX 1050 Max-Q graphics, 802.11ac WiFi, Bluetooth 5.0, and more. You can visit the product page for the full specs, as I’ll focus a bit more on the ScreenPad in this post. The ScreenPad in this laptop is a […]
Intel Core Y-series and U-series 8th Gen Processors Target Laptops with Built-in Gigabit WiFi, Optional LTE Connectivity
We discovered three Intel Amber Lake processors with a 5W TDP through a leak last month namely Core m3-8100Y, Core i5-8200Y, Core i7-8500Y dual core/quad thread processors. Intel has now made an announcement confirming the launch of Core Y-series (formerly Amber Lake, 5W TDP) and Core U-Series (Whiskey Lake, 15W TDP) 8th generation processors featuring Gigabit WiFi, optional support for LTE and targeting laptop and 2-in-1 hybrids. Intel Core Y-Series “Amber Lake” Processors Let’s start with the 5W Core-Y family key features: 4MB Smart Cache Intel HD Graphics 615 Intel High Definition Audio with digital surround sound, support for multiple audio streams, jack re-tasking. Intel Smart Sound Technology – Dedicated audio Digital Signal Processor designed to process audio for media playback and voice for PC interactions like Cortana, Nuance Dragon, or Skype. USB 3.0 – Up to 5x USB 3.0 ports supporting up to 5 Gbps USB 2.0 – Up […]
Check for Spectre, Meltdown, and L1 Terminal Fault Vulnerabilities with Spectre-meltdown-checker Script
Yesterday, we wrote a little bit about the new speculative execution vulnerability known as L1 Terminal Fault (L1TF) or Foreshadow, and a reader – MHSadri – pointed to an interesting script that checks for all three speculative execution vulnerabilities, and runs in Linux and BSD (FreeBSD, NetBSD, DragonFlyBSD) across multiple architectures: Intel x32, AMD64, Arm and ARM64. Other architectures will also work, but mitigation reporting may not be correct. So I tried it on my own machine, a computer running Ubuntu 18.04 on an AMD FX8350 processor. Installation is easy:
1 2 |
git clone https://github.com/speed47/spectre-meltdown-checker/ cd spectre-meltdown-checker |
The developer recommends to check the script manually first, just for security sake. You can have two way to run it: either directly inside your OS, or via docker which may be a better idea since it would not be able to mess with your system especially I had to run it with sudo to avoid permission issues. Here’s […]
More Speculative Execution Exploits – Meet Foreshadow / L1 Terminal Fault
Speculative execution is a feature to speed up performance of recent processors which works by predicting and loading likely future instructions ahead of time. The features became somewhat famous a few months ago with Meltdown and Spectre vulnerabilities exploiting the features. The exploits impact Intel, AMD, Arm, and other processors to various degrees, and since the feature is built-in into the hardware, there’s no easy fix, and instead operating systems vendors, cloud service providers, hosting services and other stakeholders implemented mitigations. While a lot of progress has been made, work is still going on with the just released Linux 4.18 still getting some code changes related to the exploits. But just as solutions were found for Spectre and Meltdown, a new speculative execution exploitation has raised its ugly head: L1 Terminal Fault also known as Foreshadow. The new flaw appears to be just as serious, and a dedicated website has […]
Three 5W Intel Amber Lake Processors Coming Soon: Core m3-8100Y, Core i5-8200Y, Core i7-8500Y
When I talk about low power Intel processors, I usually think about atom-based families like Bay Trail, Cherry Trail, Apollo Lake or Gemini Lake with 2W to 10W processors that delivers entry-level performance at a reasonable price. But Intel has also been selling more powerful Core-m processors with a similar power budget, but with much better performance, at the cost of a significantly higher price tag. The company is now prepping to launch a new family of such processor with Amber Lake Y-series (aka Amber Lake-Y) family. Three Amber Lake processors are expected to be officially announced very soon: Core m3-8100Y dual core/quad thread processor @ 1.1 GHz (base) / 3.4 GHz (turbo) Core i5-8200Y dual core/quad thread processor @ 1.3 GHz (base) / 3.9 GHz (turbo) Core i7-8500Y dual core/quad thread processor @ 1.5 GHz (base) / 4.2 GHz (turbo) All three processors are manufactured with a 14 nm […]
Canonical Releases Ubuntu 16.04 LTS Certified for Intel NUC
In the x86 world, the theory is that you can take a single Linux distro image should work on any x86 compatible hardware. But for Atom-class processors however, including Bay Trail, Cherry Trail, Apollo Lake and Gemini Lake it has not always been the case, especially with features like audio output, Bluetooth, touchpad, and others. That’s why for example, Linuxium (Ian Morrison) decided to write isorepin.sh script in order to respin Ubuntu ISO images for such platforms and fix various issues. However, it appears Canonical and Intel have decided to take matters into their own hand, and have now released Ubuntu 16.04 LTS certified for Intel NUC mini PCs, kits, and boards for IoT deployment. Canonical made available both Ubuntu Desktop and Ubuntu Core images. Most supported devices are based on Intel 7th generation Intel Core processors: NUC7i5DNKPC Mini PC with Intel Core i5-7300U NUC7i3DNKTC Mini PC with Intel Core […]
Companies Address Concerns related to Speculative Execution Exploits: Meltdown and Spectre
Yesterday, news surfaced about a “bug” in Intel processors that could be fixed at the operating system level at the cost of a decrease in performance for some tasks, from a typical, and barely noticeable 5% hit, to a more consequent 30% hit for some specific tasks, and as we discussed yesterday I/O intensive tasks are the most impacted by the changes. While Intel (and Arm) are impacted, AMD claims not to be, and the issue was reported by major news outlets and likely impacting the stock price of the companies with Intel stock losing 3.39%, and AMD stock gaining 5.19%, so obviously every company felt the need to answer, starting with Intel’s response to security research findings: Recent reports that these exploits are caused by a “bug” or a “flaw” and are unique to Intel products are incorrect. Based on the analysis to date, many types of computing devices […]
