Cryptomining Firm Purchases Site With 223,000 GPUs

Bitcoin mining and HPC application leader Northern Data has acquired 24,000 EPYC servers along with 223,000 AMD and Nvidia GPUs from Block.one, for the price of 195 million Euros and another 170 million Euros in shares. The new GPUs and servers will make Northern Data’s server infrastructure more powerful than the world’s fastest supercomputer, the Fugaku.

Northern Data expects full installation of GPU server systems to be complete by Q3 of 2021, with servers installed across several countries including Norway, Sweden, the Netherlands, and Germany. The added hardware will boost Northern Data’s raw compute power by more than double, going

Testing Phanteks’ T30-120: Dethroning Noctua’s Finest

A few months ago, when I was visiting Phanteks to pick up a case for review, I spotted something in the corner of my eye: A fan that I hadn’t seen before. I asked about it, but was quickly told that I wasn’t supposed to see that and swiftly hushed out the door. Fast forward to today, and I have four Phanteks T30-120 fans on the test bench, along with a wind-tunnel to put it through its paces.

All Phanteks told me back then was that this fan would be better than Noctua’s

Voltage manipulation can bypass hardware security on AMD’s server CPUs

Why it matters: Researchers from the Technische Universität Berlin have demonstrated that AMD’s Secure Encrypted Virtualisation (SEV) technology can be defeated by manipulating input voltages, compromising the technology in a similar way to previous attacks against its Intel counterpart.

SEV relies on the Secure Processor (SP), a humble Arm Cortex-A5, to provide a root of trust in AMD EPYC CPUs (Naples, Rome and Milan — Zen 1 through 3).

The research paper — toting the amusing-yet-wordy title of “One Glitch to Rule Them All: Fault Injection Attacks Against AMD’s Secure Encrypted Virtualization” — describes how an attacker could compromise the

Why Windows 11 is forcing everyone to use TPM chips

Microsoft announced yesterday that Windows 11 will require TPM (Trusted Platform Module) chips on existing and new devices. It’s a significant hardware change that has been years in the making, but Microsoft’s messy way of communicating this has left many confused about whether their hardware is compatible. What is a TPM, and why do you need one for Windows 11 anyway?

“The Trusted Platform Modules (TPM) is a chip that is either integrated into your PC’s motherboard or added separately into the CPU,” explains David Weston, director of enterprise and OS security at Microsoft. “Its purpose is to protect

AMD and Valve Working on CPU Driver That Could Boost Steam Deck Performance

According to a report from Phoronix, AMD and Valve are working together to design a better CPU performance scaling driver for Linux, targeting the Steam Deck gaming console. 

Valve has recently launched its Steam Deck gaming console that houses AMD’s custom Ryzen APU with embedded RDNA 2 GPU and Zen 2 CPU powered by a Linux-based Arch operating system (OS). Given that this system runs a Linux-based OS, Valve has to optimize the software as much as possible to ensure a smooth and consistent gaming experience across various AAA titles.

According to the report, Valve has been improving the

Gigabyte Releases 1200W PSU with Built-in Color Monitor

You can never have have enough screens, even if some of them are inside of your case. Gigabyte’s new Aorus P1200W power supply features a full-color LCD screen, which can display custom text, pictures, GIFs, and even videos on its LCD screen. Yes, just imagine watching your favorite movies on the side of your PSU!

This isn’t the first time we’ve seen a power supply with a screen slapped on it. The ASUS ROG Thor has one, but it only displays power draw, not your favorite films. Of course, the more practical use case for a screen on a PSU

Windows 365 Generally Available, Starting at $20

Nowadays we use so many physical client PCs and so many programs that keeping the same set of software on all devices is complicated. This is where Microsoft’s Cloud PC paradigm comes into play: the software giant is essentially lending a PC that is located somewhere in its datacenters and is available for any Internet-connected client everywhere in the world. 

For now, Microsoft positions its Windows 365 for business (for organizations with up to 300 employees) and enterprise customers (for organizations with more than 300 employees), two types of the company’s customers that perhaps need cloud PCs the most. As

Just like the Nintendo Switch, the Steam Deck is the result of failed hardware

The Steam Deck is set to become the handheld gaming PC of many players’ dreams when it launches next year, but Valve staffers have come forward to say it likely wouldn’t have happened if it wasn’t for some of Valve’s more notable flops – such as the Steam Machine.

The Steam Machine was a kind of pre-built gaming PC running a Linux-based operating system known as SteamOS. Valve didn’t manufacture them itself, instead working in collaboration with third-party manufacturers like Alienware. While you can still get Steam Machines here and there, though, they didn’t exactly set the market alight, and

Scientists Just Simulated Quantum Technology on Classical Computing Hardware

Lurking in the background of the quest for true quantum supremacy hangs an awkward possibility – hyper-fast number crunching tasks based on quantum trickery might just be a load of hype.

 

Now, a pair of physicists from École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland and Columbia University in the US have come up with a better way to judge the potential of near-term quantum devices – by simulating the quantum mechanics they rely upon on more traditional hardware.

Their study made use of a neural network developed by EPFL’s Giuseppe Carleo and his colleague Matthias Troyer back in

Google planning Silicon Valley campus, hardware lab

Google is asking the city for feedback on its early plans to transform a Silicon Valley office site with “sustainability” features.

City of San Jose filings

Google is planning yet another Silicon Valley campus, which will sit adjacent to a new center partly devoted to hardware, according to preliminary plans obtained by CNBC.

Beginning in 2018, Google spent more than $389 million on land in north San Jose, Calif., and the company has since filed detailed preliminary proposals showing a sneak peak of its plans for the space. The plans, which are filed as an “R&D” facility, show a center
