AMD’s overclockable Ryzen 9 5900 HX-series chips can boost up to 4.8GHz

After Intel kicked things off on Day 1 of CES 2021, AMD has punched back with its own impressive processor launch, all centering on its Ryzen 5000 mobile chips. They’ve long been rumored, especially since the debut of their desktop counterparts in late 2020. But today, they’re official.

AMD CEO Lisa Su took to the stage and announced theinitial Ryzen 5000 chips in the lineup, all based on the Zen 3 core architecture. The first is the Ryzen 7 5800U, which fits eight cores and 16 threads into a 15-watt power envelope for thin-and-light laptops. Su reminded the audience that it’s still the only x86 system with eight cores in a 15-watt TDP.

Su also focused on battery life, promising that the Ryzen 7 5800U would last for 17.5 hours on a single charge in general usage and up to 21 hours in video playback.

AMD also announced a couple of new 45-watt gaming or high-performance chips in the Ryzen 9 HX series, which is new to Ryzen 5000. They include the Ryzen 9 5900HX and the Ryzen 9 5980HX. While both have eight cores and 16 threads, the Ryzen 9 5980HX has a higher top boost speed of up to 4.8GHz.

AMD compared these unlocked chips to Intel’s Core i9-10980HK, where it shows a double-digit competitive edge percentagewise. It’s not only in multi-core performance either, which has always been Ryzen’s strength. That higher clock speed is even letting AMD taking the lead in single-core performance in Cinebench R20, which is impressive.

AMD also showed the Ryzen 5900HX Radeon integrated graphics beating Intel’s offering by 19% in the Fire Strike Physics benchmark.

AMD didn’t go in-depth on these new processors, nor did it provide any information about lower-end processors such as Ryzen 5.

Su promised up to 150 laptop designs using Ryzen 5000, which is up from 50 implementations of Ryzen 4000 in 2020. That growth is telling, and shows just how far AMD has come in just a couple of years.

These mobile processors build on the intense momentum being generated by AMD. The company announced Ryzen 4000 mobile chips at CES last year, and followed that up with its Ryzen 5000 desktop chips in late 2020. They’ve been sold out ever since, keeping the demand high for AMD’s high-performance chips well into 2021.

Don’t try this $3 app that makes your MacBook moan, but I know you want to
This absurd $3 Mac app went viral for all the wrong reasons
Computer, Electronics, Laptop, MacBook

There are useful apps, there are pointless app,s and then there is SlapMac, which sits in a category all by itself.

This app has gone viral online for one very stupid (and fun) reason: it makes your MacBook play sound effects when you slap it. Just spank your Mac and hear it moan, fart, or throw punches. The app creator has apparently made $5,000 in just three days, which is what makes the story even more absurd.

Apple’s ridiculous $700 wheels for its desktop PC are gone for good
The $700 Apple wheels are dead, long live ridiculous tech accessories
Machine, Wheel, Tire, Apple Mac Pro Wheels

Apple has officially discontinued the Mac Pro, and by extension, the $700 Mac Pro Wheels Kit is also dead.

Yes, that sentence is still funny in 2026. It marks the end of one of the company's most infamous desktop add-ons. For anyone who somehow missed this saga, the Wheels Kit launched back in 2020 as an upgrade for the Mac Pro. It allowed you to add wheels for $400, but buying the standalone kit later costs a whopping $700 because the base machine already included the standard feet. Apple also sold a separate $300 Feet Kit for people who wanted to swap back.

Apple's MacBook Neo arrived as a shock to the industry. It is the new cheap MacBook that is designed to be silent, efficient, and affordable. But a new stress test suggests that it could have been noticeably better with a very simple change.

As per a recent test, the addition of a basic copper plate to the cooling setup can improve both thermals and performance by a meaningful margin. And the frustrating part? It isn't some complex engineering overhaul and is relatively straightforward.
