Silvermont: Intel's promise to power phones and tablets you'd actually want

Silvermont: Intel's promise to power phones and tablets you'd actually want

Today, nearly all modern smartphones use an ARM-based processor, along with every iPad and practically every Android tablet as well. Soon, though, Intel's x86 silicon might finally pose a challenge. Six years after laying out a roadmap for power-efficient processors for tiny computers, and several failed attempts to make a real dent, Intel impressed us last October with just how power-efficient its Medfield chip could be compared to the latest Qualcomm Snapdragon. That chip used the company's Saltwell core inside, but this year the company's introducing Silvermont, and Intel claims the new 22nm architecture will more than hold its own against the best ARM has to offer.

Intel promises three times the performance, or the same performance at five times lower power than the current gen Atom core, a truly serious boost. In charts (see below), Intel showed us how its dual-core processor can theoretically trounce the competition's quad-cores at one watt, and how a quad-core Silvermont-based chip, like the Bay Trail that will appear in tablets and cheap notebooks late this year, should be able to wipe the floor with the competition with just 1.5 watts of power at its disposal. "If you have an efficient solution, you don't need to play the core count game," Intel Fellow Belli Kuttanana told reporters at a press conference.

But more CPU power and / or longer battery life is only part of the story. Over a year ago, we heard that the next Atom family would have a drastic improvement in graphics capabilities, switching from an aging, smartphone-class PowerVR SGX 535 or 545 GPU to a few of the same Intel HD GPU cores that the company puts in its latest laptop and desktop processors. At the press conference, a company rep wouldn't go quite that far, but confirmed that both the CPU and GPU in Bay Trail would offer double the performance. That's fantastic news for anyone buying a low-power Windows 8 tablet, which performed much better than their ARM-based Windows RT competition but still weren't quite what you'd expect from a full computer. With Silvermont, processor expert Anand Shimpi says we could possibly see performance out of an Atom computer equal to that of a MacBook Air from 2010.

And if those charts lie, or for whatever reason Intel doesn't manage to rustle up the partners and / or marketing campaign needed to convince OEMs and cellular carriers to build Intel-based tablets and phones, Intel should have an even better chance to wow the market next year, when it goes straight from 22nm Silvermont to a (theoretically) even more power-efficient 14nm with Airmont in 2014.Tick, tick, tickStarting with Silvermont, the company's promising to update its mobile Atom silicon each and every year with a regular cadence, similar to the famous "tick-tock" strategy that won Intel the lion's share of the desktop and laptop market in previous years. Intel finally seems to be dead-serious about mobile, and if it can manage to deliver the goods as planned, the next time you buy a $200 Android tablet, it might be the highest performing device on the market due to Intel's plans.

Get ready for some Netflix news.

At 1PM ET today Netflix is streaming its second annual Tudum event, where you can expect to hear news about and see trailers from its biggest franchises, including The Witcher and Bridgerton. I’ll be covering the event live alongside my colleague Charles Pulliam-Moore, and you can also watch along at the link below. There will be lots of expected names during the stream, but I have my fingers crossed for a new season of Hemlock Grove.

Looking for something to do this weekend?

Why not hang out on the couch playing video games and watching TV. It’s a good time for it, with intriguing recent releases like Return to Monkey Island, Session: Skate Sim, and the Star Wars spinoff Andor. Or you could check out some of the new anime on Netflix, including Thermae Romae Novae (pictured below), which is my personal favorite time-traveling story about bathing.

Has the Windows 11 2022 Update made your gaming PC stutter?

Nvidia GPU owners have been complaining of stuttering and poor frame rates with the latest Windows 11 update, but thankfully there’s a fix. Nvidia has identified an issue with its GeForce Experience overlay and the Windows 11 2022 Update (22H2). A fix is available in beta from Nvidia’s website.

If you’re using crash detection on the iPhone 14, invest in a really good phone mount.

Motorcycle owner Douglas Sonders has a cautionary tale in Jalopnik today about the iPhone 14’s new crash detection feature. He was riding his LiveWire One motorcycle down the West Side Highway at about 60 mph when he hit a bump, causing his iPhone 14 Pro Max to fly off its handlebar mount. Soon after, his girlfriend and parents received text messages that he had been in a horrible accident, causing several hours of panic. The phone even called the police, all because it fell off the handlebars. All thanks to crash detection.

Riding a motorcycle is very dangerous, and the last thing anyone needs is to think their loved one was in a horrible crash when they weren’t. This is obviously an edge case, but it makes me wonder what other sort of false positives we see as more phones adopt this technology.

Ford is running out of its own Blue Oval badges.

Running out of semiconductors is one thing, but running out of your own iconic nameplates is just downright brutal. The Wall Street Journal reports badge and nameplate shortages are impacting the automaker's popular F-series pickup lineup, delaying deliveries and causing general chaos.

Some executives are even proposing a 3D printing workaround, but they didn’t feel like the substitutes would clear the bar. All in all, it's been a dreadful summer of supply chain setbacks for Ford, leading the company to reorganize its org chart to bring some sort of relief.

Doing more with less (extravagant holiday parties).

Sundar Pichai addressed employees’ questions about Google’s spending changes at an all-hands this week, according to CNBC.

“Maybe you were planning on hiring six more people but maybe you are going to have to do with four and how are you going to make that happen?” Pichai sent a memo to workers in July about a hiring slowdown.

In the all-hands, Google’s head of finance also asked staff to try not to go “over the top” for holiday parties.

Insiders made the most money off of Helium’s “People’s Network.”

Remember Helium, which was touted by The New York Times in an article entitled “Maybe There’s a Use for Crypto After All?” Not only was the company misleading people about who used it — Salesforce and Lime weren’t using it, despite what Helium said on its site — Helium disproportionately enriched insiders, Forbes reports.

Nvidia’s latest AI model generates endless 3D models.

Need to fill your video game, VR world, or project render with 3D chaff? Nvidia’s latest AI model could help. Trained on 2D images, it can churn out customizable 3D objects ready to import and tweak.

The model seems rudimentary (the renders aren’t amazing quality and seem limited in their variety), but generative AI models like this are only going to improve, speeding up work for all sorts of creative types.
