The Second Video Worth Sharing Today: The Full Review on the HP Envy X2 Win 10 on ARM 2 in 1 PC

By Tim

This one comes to us from Andrew over at AMDTech and covers the details on the HP Envy X2 using Win10 on ARM.

The battery life is amazing but the new tech here suffers from, well, being bleeding edge, but not yet refined. The Qualcomm Snapdragon 835 works okay, but doesn’t handle 64 software at all.

As usual this is another well made, brutally honest review, which is why you should be subscribed to Andrew’s channel! We did post the initial impressions review a few weeks back and you can find that one right here.

So let us get right to that video and see what Andrew has to say!

That will about cover it for the moment,

Tim

Microsoft Accidentally Unveils Windows 10 on ARM Limitations

By Radu Iorga

Today’s news is marked by a rather atypical blunder from Microsoft, who unveiled a list of limitations for the Windows 10 on ARM platform. Turns out that some driver incompatibilities may occur and we detailed them below.

Windows 10 on ARM debuted last fall, with the promise of bringing always on LTE connectivity to laptops and also 20+ hours of battery life. Some models are even predicted to have 30 hours of battery life. Now there were obvious limitations to be expected, with people worrying about x86 compatibility most of all.

Microsoft managed to leak a full list of limitations for the platform, which they also quickly deleted. The list, shown in full here reveals that Windows 10 on ARM will only support ARM64 drivers. This is a problem with people with older peripherals or accessories.

Windows 10 on ARM doesn’t quite allow emulation of x86 apps, but apparently that’s also coming at some point. Another problem on the list is the fact that apps and games that need OpenGL version 1.1 or latter won’t work on the platform. Also, those new fangled games with anti cheat technology also will not work on it.

Right now, Qualcomm, Microsoft, HP, Lenovo and ASUS are working together to make this project happen. Frankly speaking none of the drawbacks above bothers me terribly if I get 20 hours of battery life and LTE.

Windows 10 on ARM limits (briefly) confirmed: No virtualization, no OpenGL

As spotted by Paul Thurrott, Microsoft briefly published a document that enumerated the major differences between Windows 10 for ARM processors and Windows 10 for x86 chips. Though the document has now been removed, a cached copy is still available.

Many of the differences are predictable consequences of the different architecture. Windows 10 for ARM is a 64-bit ARM operating system. It can natively run both 32-bit and 64-bit ARM applications (though the SDK for the latter is currently, and temporarily, incomplete). As such, drivers for the operating system need to be 64-bit ARM drivers; existing 32- and 64-bit x86 drivers won’t work.

This isn’t a surprise; 64-bit x86 Windows can’t use 32-bit drivers, either, even though 64-bit Windows can generally run 32-bit applications without even requiring any kind of emulation. This will mean that ARM Windows has limited hardware support relative to x86. It will also pose a problem for some games that use drivers for their copy protection.

Xiaomi Expected to Launch Snapdragon 835-Based Laptop With Windows 10 Next Year

By Radu Iorga

After the debut of Windows 10 on ARM a few weeks ago, we expected more and more partners to adhere to this initiative. ASUS and HP kicked things off, with Lenovo also promising to join the party. Acer should also be there soon and now Xiaomi is said to have its own Snapdragon 835 powered laptop ready for prime time.

This laptop is slated for a 2018 debut, with Windows 10 in tow. Xiaomi and Qualcomm have been getting cozy lately, as Xiaomi also announced that it will be one of the early adopters of the Snapdragon 845 processor next year. The Chinese device maker is still a new name on the laptop market, entering it last year with the Mi Notebook Air. Then we saw the Mi Notebook Air with 4G SIM card slot and 2018 may bring a laptop of the sort with a Snadpragon 835 CPU inside.

The current gen Xiaomi laptops are based on Intel CPUs and Xiaomi’s key selling point for its laptops is the battery life. As you know, Snapdragon 835 laptops have amazing battery life, around 20 hours or more, so Xiaomi may also want a piece of that. Gigabite LTE connections is another advantage. Xiaomi is also rumored to bring its laptops to India, since they were only available in China till now. With their recent debut in Spain and soon in France we could also see them expanding there the laptop offer.

Right now those looking for a Win on ARM laptop can choose between the ASUS NovaGo and its 22 hours of functioning or the HP Envy x2 2 in 1 laptop with 6.9 mm waistline. They’ll be sold in early 2018. Expect a lower price from Xiaomi compared to those offered by HP and ASUS. I also expect Samsung to get in on the action.

Snapdragon 845 unveiled with 25-percent faster CPU, 30-percent faster graphics

By Ron Amadeo

Qualcomm is hosting the “Snapdragon Technology Summit” in Hawaii this week, where it unveiled its flagship system-on-a-chip (SoC) for 2018: the Snapdragon 845. Qualcomm has a near-monopoly on the high-end smartphone SoC market, so unless you’re buying an iPhone or non-US Samsung phone, you can expect most 2018 flagship smartphones to be powered by Qualcomm’s latest. You might even see the chip in your next laptop, with Qualcomm breaking into the Windows 10 market.

The SoC is manufactured by Samsung on the company’s 10nm process, just like the Snapdragon 835. The Kryo 385 is once again a derivative of ARM’s Cortex CPU, with four “performance” cores (based on the Cortex A75) clocked at up to 2.8GHz and four “efficiency” cores (based on the Cortex A55) that run at up to 1.8GHz. Qualcomm is boosting the performance core clock speeds by 19 percent over the Snapdragon 835, but thanks to a CPU redesign, Qualcomm is promising a “25-percent performance uplift” over the previous generation. The CPU also gets a new 2MB L3 cache and 3MB of system cache.

The GPU is now the Adreno 630, and Qualcomm is promising “30-percent faster graphics” and “30-percent better power efficiency.” The company says a 2.5×-faster display throughput will allow for a 2K×2K display at 120Hz. Qualcomm is really pushing AR and VR with the Snapdragon 845, promising out-of-the-box support for eye tracking, hand tracking, foveated rendering (adding more detail to the part of the screen you’re looking at), multiview rendering (great for rendering the left and right eyes in VR goggles), and HTC Vive-style six degree of freedom (6DoF) tracking for headsets and controllers. In fact, the Adreno 630 GPU isn’t even called a “GPU” anymore—now it’s a “Visual Processing Subsystem.” It’s not that any of this was impossible before, but now Qualcomm is officially supporting all of these VR/AR use cases out of the box.
