New Chrome OS bug causes high CPU usage every time you check CPU usage, understands irony

Early adopters are used to dealing with bugs (or they should be), but once in a while a hidden problem can trickle down into stable, though rarely are they so funny as this. Some folks are running into issues with Chrome OS Stable v72 and later releases, resulting in crazy high CPU use. The twist? This problem only occurs in very particular, self-fulfilling circumstances: while you have the task manager open.

Qualcomm's new Snapdragon 850 is a processor built with laptops in mind

Qualcomm has announced what is technically a new chipset today in the upcoming Snapdragon 850 - and it's probably not what you think. While it could power your next laptop (maybe), you almost certainly won't be seeing the Snapdragon 850 in your next phone.

Qualcomm seems to be changing its processor naming strategy once again, because logically, you'd think the Snapdragon 850 would be the next iteration of its flagship mobile platform, but in fact it's just a Snapdragon 845 designed with laptop and similar form factors specifically in mind. What's that mean? It's not clear exactly, but if you look at the specifications, you'll see a Snapdragon 845 - Kryo 385 CPU cores, Adreno 630 GPU, Hexagon 685 DSP, 1.2Gbps LTE, and Spectra 280 image signal processors.

'Spectre' and 'Meltdown' CPU vulnerabilities become public, most Google products already protected

A report from The Register yesterday claimed that Windows and Linux developers were scrambling to fix a "fundamental design flaw in Intel's processor chips." The flaw theoretically allows any program to view the layout or contents of protected kernel memory areas, which often contain passwords, login keys, cached files, and other sensitive data. Even a web app could potentially read kernel-protected data.

Qualcomm announces the Snapdragon 660 and 630

Qualcomm has announced two new platforms today, the Snapdragon 660 and 630, meant to supplant the 653 and 626 respectively. Both are built on the company's latest 14nm FinFET process. They are also each part of Qualcomm's so-called "High tier," which rests — as one would numerically assume — between the 800 and 400 tiers. I don't want to oversimplify too many details of this release since it is very nifty, but at the same time I would like to ensure the information I'm presenting is accessible, so forgive me if I occasionally digress and/or geek out.

MediaTek announces the new Helio X23 and X27 deca-core mobile processors

The name MediaTek is usually associated with lower-end Chinese smartphones and tablets, since their SoCs are rather inexpensive. In the last year or so, the chip manufacturer has been working to push past that reputation. When it introduced the Helio X20, a few people took notice. Innovation is not usually the game with MediaTek, but it does try some interesting CPU designs. Today, it revealed the new Helio X23 and Helio X27 mobile processors.

Geekbench 4 now available on Android for all your benchmarking needs

Earlier this month, I wrote about possibly the worst benchmarking application I had ever seen, 'Nenamark.' But Geekbench has come to save the day, bringing their Geekbench 4 benchmarking utility to Android. Geekbench is another cross-platform benchmarking program, so you can compare your results to a wide range of devices.

The Android Geekbench app, at least compared to the Windows/macOS equivalents, seems rather simplistic. You can benchmark your device's CPU and GPU, which are displayed as a number at the end (unlike Nenamark). The CPU benchmark performs both single-core and multi-core results, which is a nice touch. Unfortunately, Geekbench's battery test has been removed in this version.

Editorial: Snapdragon Sorrows - Has Qualcomm Begun A Long, Slow Fall From The Top?

Back in late July, the Qualcomm Corporation - employer of over 30,000 individuals at the time - began the process of telling about 15% of those people (eg, over 4,000 gainfully-employed human beings) they were no longer needed. This was after already cutting another 1500 jobs in late 2014.

The company's stock is currently trading near 2-year lows, and while obviously still a very robust company, Qualcomm can't keep putting in these kinds of numbers if it's going to maintain its position at the tippy-top of the smartphone chipset market.

Qualcomm (QCOM - NASDAQ) stock is down over 10% year-to-date. It is down over 20% from its peak, reached in early 2014.

Report: Samsung Drops Qualcomm's Snapdragon 810 From The Next Flagship Galaxy Phone

Samsung and Qualcomm have been reliable partners since the rise of Android, to the mutual benefit of both the phone maker and the OEM chip supplier. But according to this report from Bloomberg, that relationship has hit a rocky patch as Samsung prepares its next flagship phone, presumably the Galaxy S6. An anonymous tipster told Bloomberg that Samsung will decline to use a Qualcomm chipset for the phone after poor testing of the Snapdragon 810, the OEM's top-of-the-line processor.

According to the report, Samsung has found that the 810 often overheats during testing, causing the company to choose its own line of Exynos processors instead.

ARM Announces New Mid-Range Designs, MediaTek Already Has Chips Ready To Go

ARM technology powers the vast majority of mobile devices in the world, and the company has just announced some new designs to continue that tradition. The ARM Cortex-A17 is a new mid-range CPU core that offers improved speed and efficiency for budget devices. That's not all – there is also a new version of the Mali GPU for a complete price-conscious package.

Cortex A12 Mali-T720MP-LG

The Cortex-A17 is not meant to replace the A15 – that's still the flagship CPU core design from ARM. The A17 is a mid-range part that should give chip makers a better option than continuing to use older A9s, the limited A12, or just a bunch of low-power Cortex-A7 cores.

Did You Root Android 4.3 With Chainfire's SuperSU? Update To v1.43 To Fix The 100% CPU Bug

If you've already updated to Android 4.3, whether via an OTA or by flashing it manually, and rooted it, you're more than likely using Chainfire's SuperSU, which carefully works around the new restrictions Google put in place. Cody has a good write-up about why they did it and what's going on, so go read that if you're interested in the details.

Chainfire created the Android 4.3-compatible root method and the updated SuperSU back when the first leaks showed up for the Galaxy S4 but hasn't updated it for a few weeks. During that time, a good portion of users have discovered that sometimes SuperSU causes CPU spikes and starts eating up 100% CPU.
