ARM shows off the first processors based on Dynamiq technology

An ARM processor.
In March, ARM, the holding company that designs the chips in billions of phones, cars, and mobile devices, announced Dynamiq, a new platform that promised performance and efficiency improvements over current-gen architectures. Since then, details on new chips have been hard to come by, but that all changed Sunday evening with the introduction of the Cortex-A75 and Cortex-A55 processors — the first based on Dynamiq — and the Mali-G72 graphics chip

ARM is promising “ground-breaking performance” with the Cortex-A75, which performance gains as high as 50 percent in areas such as artificial intelligence. ARM calls the Cortex-A75  “laptop-ready,” and sees it best suited for large-screen devices, networking equipment, and cars.

The Cortex-A55, on the other hand, doubles down on power efficiency. It’s up to 2.5 times more efficient compared to ARM’s current crop of processor and tailored for “everyday devices” like tablets, smartphones, and Internet of Things (IoT) devices.

Both the Cortex-A55 and Cortex-A75 benefit from a fast single-thread performance and Dynamiq’s new Big.Little configuration, an ARM technology that intelligently switches between processor cores as needed. The Cortex-A75 has four high-power cores (Big) and four low-power cores (Little), and the Cortex-A55 has 1 high-performance core (Big) and seven low-power cores (Little).

Other platform changes include CryptoCell-712, the newest version of ARM’s subsystem security architecture, and native support for high dynamic range (HDR), a high-contrast display standard.

New processors are not the only thing ARM had up its sleeve. It took the wraps off the Mali-G72, a next-gen GPU.

Enhanced graphics are the chip’s headlining feature. ARM said the Mali-G72 is 25 percent more power efficient and cuts down on bandwidth by 87 percent, leading to 1.4 times better overall performance than the 2017 devices.

ARM said the beefed-up chip will benefit virtual reality and “high fidelity” apps. To that end, the Mali-G72 supports mobile multi-view, an advanced rendering feature for Samsung’s Gear VR headset; foveated rendering, a technique that uses an eye tracker integrated with a VR headset; adaptive scalable texture compression (ASTC), a compression algorithm that supports HDR and multiple color formats; and multisample anti-aliasing (MSAA), which improves image quality by smoothing out the rough edges of objects.

ARM’s targeting AI applications with the Mali-G72, too. New algorithms and other optimizations make it 17 percent more efficient at on-device AI computing, ARM said, making it the “most efficient Mali GPU for machine learning [yet].”

ARM said devices equipped with the Mali-G72 and either the ARM-A75 or ARM-A55 will be capable of “real-time inference” and “on-device learning” that enhances user privacy and powers and new, intuitive user interfaces. “[The new chips] have [the] compute performance to deliver a hi-fidelity world,” ARM said. “[It’s] AI in your hand.”

ARM’s building on the success of its existing chip business. The company said that more than a billion Mali chips shipped in 2016 and that 50 percent of mobile virtual reality headsets and 50 percent of smartphones pack the chip. It is projected to ship 100 billion chips between 2017 and to its more than 450 silicon partners and 1,000 community partners, which doubles the 50 billion in shipped between 2013 and 2017.

Screen on the Alienware x16.

Gaming laptops are a great option for prospective PC gamers who don't want to mess around with building their own PC. Take this Alienware x16 gaming laptop: It comes ready to play right out of the box, with some powerful components and a sweet deal. Right now, as part of Dell gaming laptop deals you can grab this configuration of the Alienware x16 for $3,000 after a $600 discount to its base price. Alienware deals come and go quickly, so jump on this one soon if you're interested. You can read more about the components in this machine below.

Why you should buy the Alienware x16 Gaming Laptop
The most important aspect of any gaming laptop is the components. This x16 configuration has the Intel Core Ultra 9 processor and an Nvidia GeForce RTX 4090 GPU. That's a beefy graphics card that tests the balance between overkill and price. It will have no problem running the newest AAA games for a few years. With 16GB of RAM in the graphics card and the additional 32GB in the full machine, you'll have snappy performance. There are 2TB of SSD storage We'd like to call that "more than enough," but if you're playing a lot of modern PC games, you know that they're getting bigger and bigger each year. It might be worth grabbing some external hard drive deals.

The best data recovery software for your Mac or MacBook
A rose gold MacBook Air has Disk Utility open with a red warning symbol and an external drive connected.

Apple designed your computer to be reliable and user-friendly, but even the best and newest MacBook hardware can experience glitches. When something goes wrong with your storage, data recovery software can help you restore missing and damaged files.

Another reason for data loss is the sort of embarrassing mistake that happens sometimes. If you've ever accidentally thrown away a file you needed, then emptied the trash, it's possible to get that file back with a data recovery app.
