Samsung’s new phone storage standard is twice as fast

Samsung has introduced the latest iteration of its Universal Flash Storage product, which it says is much, much faster than its predecessor. The UFS specification was already developed to enable SSD speeds for cameras, phones and other devices, but this version — called UFS 4.0 — has a speed that reaches 23.2Gbps per lane. That’s double the speed of UFS 3.1, the standard used by Samsung’s S22 flagship phones. The tech giant says its huge bandwidth makes it perfect for 5G smartphones that typically require huge amounts of data processing. Samsung also expects it to be adopted for use in the automotive industry, as well as for augmented and virtual reality devices.

The flash storage features Samsung’s 7th-generation V-NAND solution and proprietary controller, and the company says those help it deliver sequential read speeds of up to 4,200MB/s and sequential write speeds of up to 2,800MB/s. It’s a lot more power efficient, as well, with a 46 percent improvement over the previous generation that could translate to longer battery life. Samsung’s USF 4.0 devices will have max measurements of 11mm x 13mm x 1mm and will come in several capacities up to 1TB.

The company will begin mass producing UFS 4.0 storage products in the third quarter of 2022. Right now, Samsung says it’s “collaborating with smartphone and consumer device manufacturers globally” and “working vigorously to foster an ecosystem for UFS 4.0 to drive the market for high-performance mobile storage solutions.”

AMD teases new ‘Dragon Range’ CPUs for high-end gaming laptops

With the release of its Q1 2022 financial results, AMD also revealed plans for its upcoming Ryzen 7000 Zen 4 series laptop CPUs, as seen in a slide tweeted by former Anandtech editor Dr. Ian Cutress. It’s planning to target “extreme gaming laptops” with the new “Dragon Range” series, promising the “highest core, thread and cache ever for a mobile gaming CPU.” It also unveiled the Phoenix series for thin and light gaming laptops.

The Dragon Range features a >55 watt TDP and is designed for laptops thicker than 20mm that are largely designed to be used while plugged in, The Verge reported. They’ll feature a PCIe 5 architecture and DDR5 RAM, though some models could work with more efficient but lower performing LPDDR5, AMD told Cutress. 

As with the Ryzen 9 4900HS chip, the Dragon Range will use the “HS” suffix. Despite the relatively high 55 watt TDP, they’ll be “notably more power efficient than other laptops in that competing timeframe,” according to AMD’s technical marketing director, Robert Hallock. 

Along with the Dragon Range, AMD will launch the Ryzen 7000 Zen 4 “Phoenix” series APUs designed for thin and light laptops under 20mm thick with 35-45 watt TDPs. Those will also use a PCIe 5 architecture, but come primarily with LPDDR5 RAM. As with the Dragon Range, some models could employ DDR5 memory, too.

Ryzen 7000 will launch first on desktop later this year with the the Raphael series, replacing the Ryzen 5000 lineup. Those will be the first Zen 4, AM5 platform chips using TSMC’s 5-nanometer process node to come to the mainstream market. AMD didn’t reveal other details about the Dragon Range and Phoenix laptop chips, but they’re expected to launch sometime in 2023. 

On the earnings side, AMD beat market expectations with revenue at $5.89 billion, a 71 percent boost in sales year-over-year. It also said that starting next quarter, it will break out gaming into a separate financial segment showing sales of chips for consoles (PS5, Xbox Series X, etc.) plus Radeon graphics for PCs as part of a single gaming business, separate from Ryzen chips. The company will explain all that in more detail next month. 

YouTube Go will no longer be available starting this August

YouTube Go is going away for good in August. The YouTube Team has announced that it’s retiring the lightweight alternative to its main app, mainly because it has become unnecessary over the years. YouTube developed the Go application for users where connectivity is spotty, mobile data prices are prohibitive and low-end phones that couldn’t run the main app as well as more expensive devices could were common. The team explained that since Go was first launched in 2016, YouTube has rolled out a number of performance improvements to the main app.

Some of those upgrades allow the main app to run more efficiently on entry-level devices and for people with slow networks. The team says it’s also working on new controls that would help people lower their mobile data usage if they have limited access to it, though it didn’t say when the new feature will be available. It’s now advising Go users to download the main application, which unlike the lightweight version allows people to comment, post, create content and use the dark theme.

YouTube Go was initially available in India and Indonesia before making its way out of beta and into wide release back in 2017. In 2018, YouTube rolled it out to over 130 countries, so more users can download the 10MB app. Now it’s time to bid it farewell. As 9to5Google notes, this raises questions about the need for Android Go in the future. The OS allows cheap phones to run faster, but there may come a time when the main Android platform can run as efficiently on low-end devices.
