AMD Zen 4 ‘Raphael’ CPUs to Have Better Thermal, Power Management: Report

AMD’s upcoming Ryzen processors based on its Zen 4 architecture are predicted to bring numerous performance improvement’s to the company’s next processors. According to a report from Igor’s Lab, AMD has also improved its power delivery and thermal output reading for Raphael.

As the report notes, AMD has been working to improve overall problems with power management and thermal readings in its upcoming CPU lineup. Given that for the past few generations we have seen reports about incorrect readings of AMD CPU temperatures, this would be welcome news.

Cooling solutions for CPUs depend on one specific CPU output and

Gigabyte Leak Reveals Zen 3 Threadripper CPUs Codenamed ‘Chagall’

Its been almost two years since the release of AMD’s current Ryzen Threadripper CPUs, giving AMD plenty of time to prepare a successor. Now, it appears that a successor is on the way, at least according to leaked details from a Gigabyte hack about new Zen 3 ‘Chagall’ Ryzen Threadripper 5000 series chips. As noted from  ComputerBase, these CPUs will max out at the same 64 Cores and 280W as Ryzen 3000 Threadripper, but feature the significantly quicker Zen 3 architecture, a recipe that is known to make the best CPUs on the market.

According to the Gigabyte leak,

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

Google Replaces Millions of Intel’s CPUs With Its Own Homegrown Chips

Google has designed its own new processors, the Argos video (trans)coding units (VCU), that have one solitary purpose: processing video. According to a recent report, the highly efficient new chips have allowed the technology giant to replace up to tens of millions of Intel CPUs with its own silicon

For many years Intel’s video decoding/encoding engines that come built into its CPUs have dominated the market both because they offered leading-edge performance and capabilities and because they were easy to use. But custom-built application-specific integrated circuits (ASICs) tend to outperform general-purpose hardware because they are designed for one workload

AMD’s Zen 5 CPUs, APUs Will Likely Tap TSMC’s 3nm Process Node

AMD’s Zen 4 processors haven’t even launched yet, and rumors are already emerging about the chipmaker’s future Zen 5 chips. Given the time frame that we expect for the Zen 5 chips to debut, the information from the leaks makes sense. Nevertheless, we still recommend you approach all rumors with caution.

The partial AMD roadmap, which originated from China, claims that AMD will market its Zen 5 processors under the Ryzen 8000 branding, with both mainstream Ryzen processors and APUs reportedly uniting under the Ryzen 8000 branding umbrella. The rumored codenames for Ryzen 8000 chips and APUs are Granite

Intel Lists Xeon W-1300 CPUs: Rocket Lake for Workstations

Intel has quietly added its Xeon W-1300 series Rocket Lake processors for entry-level workstations to its database, which essentially means they’ve had a somewhat silent introduction, at least to businesses. Unlike desktop counterparts, the new Xeon W CPUs support ECC memory and come with Xe-LP graphics featuring drivers certified for professional applications. 

The new Xeon W-1300 CPUs feature six or eight cores based on the Cypress Cove microarchitecture, a built-in GPU with 32 EUs featuring the Xe-LP architecture, AVX-512 support, 20 PCIe 4.0 lanes, and DDR4-3200 support. In general, the new processors for entry-level workstations provide the same benefits as
