Update, 8/31/2021 7:30am PT : Updated article and title to clarify that the vulnerability applies to all AMD processors, not just the Zen 2 and Zen+ models listed in the research paper. Original article: According to security researchers and AMD , the company's Zen 2 and Zen+ processors suffer from a new Meltdown-like vulnerability, but the problem appears to be far more wide-ranging. AMD has prepared a guide on mitigating the vulnerability and published details about how the vulnerability works, but the company's security bulletin also notes that all AMD CPUs are vulnerable. Called "Transient Execution of Non-canonical Accesses," this vulnerability acts very similarly to the already-disclosed Meltdown vulnerability that only impacts Intel CPUs. Saidgani Musaev and Christof Fetzer, researchers from Dresden Technology University, discovered the vulnerabilities in AMD Zen+ and Zen 2 processors. The researchers disclosed the CVE-2020-12965 vulnerability to AMD in … [Read more...] about Researchers Disclose Meltdown-like Vulnerability for AMD Processors (Updated)

AMD’s Ryzen 7000 CPUs haven’t had the best reception, but Team Red is correcting course. The new Ryzen 5 7600 is proof of that. It’s slightly slower than the Ryzen 5 7600X based on the spec sheet, but it’s around $70 cheaper, comes with a bundled cooler, and promises nearly identical performance. Contents Specs Pricing Performance Gaming AMD Ryzen 5 7600X vs. Ryzen 5 7600: Which should you buy? After testing the processor myself, I can confirm — the Ryzen 5 7600 is one of the best processors you can buy right now. With a couple of clicks, it can achieve identical performance as the Ryzen 5 7600X, and it comes in at a cheaper price. Specs Spec-for-spec, the Ryzen 5 7600X and Ryzen 5 7600 are almost identical. The biggest difference is clock speed, with the Ryzen 5 7600 having a much lower base clock speed, as well as a slightly lower boost clock speed. Otherwise, you’re getting the same six Zen 4 cores and 38MB of cache across both processors. … [Read more...] about AMD Ryzen 5 7600X vs. Ryzen 5 7600: is cheaper better? | Digital Trends

See our complete coverage of CES 2023 here There’s no doubt that AMD’s Ryzen 9 7950X is an impressive processor, but AMD’s most recent generation hasn’t been off to the best start. Like it or not, AMD’s latest chips are expensive, require a lot of power, and run hot. At CES , AMD is looking to correct course. The company introduced three non-X CPUs to go alongside its big, beefy Ryzen 7000 processors, and they address the problems with the latest generation point-for-point. They’re more efficient with a 65-watt power limit, but more importantly, they’re far cheaper than their X-branded counterparts.

AMD quietly divulged 31 new CPU vulnerabilities in a January update, spanning its Ryzen chips for consumers and the EPYC data center processors. The vulnerability update also includes a list of AGESA versions, with mitigations for the impacted processors. AMD revealed the vulnerabilities in a coordinated disclosure with several researchers, including teams from Google, Apple and Oracle, which gave the company time to develop mitigations prior to the public listings. However, AMD didn't announce the vulnerabilities with a press release or other outreach — it merely posted the lists — so we're working to tease out the details and will update when we have more information. Spectre and Meltdown . The vulnerabilities include three new variants for the consumer-geared Ryzen desktop PC, HEDT, Pro, and Mobile processors . One of the vulnerabilities is listed as high severity, while the other two are ranked as Medium or Low severity. These vulnerabilities can be exploited through either … [Read more...] about AMD Quietly Lists 31 New CPU Vulnerabilities, Issues Patch Guidance

The word on the street is that Intel will launch its 13th Generation Raptor Lake non-K processors at CES 2023 . Hardware leaker chi11eddog has shared some performance numbers for the upcoming chips. The tipster claims that a motherboard vendor conducted the tests for analysis; nonetheless, we recommend you cautiously approach the information. Core i9-13900K or Core i7-13700K , are among the best CPUs on the market. However, not everyone needs a large amount of firepower, which is where the non-K series offerings come into play. They retain the essence of their K-series counterparts, which are the core counts. However, the chips feature slightly slower clock speeds to conform to the 65W TDP. DDR5 memory. The vendor only used on benchmark (Cinebench R23) to evaluate the chips so the results only illustrate the processors’ performance in that particular software.
