Quote:HWinfo claims that X570 motherboards from a variety of manufacturers are guilty of underreporting power to Ryzen CPUs so the chips will go faster at stock settings, but at the possible expense of chip longevity. It doesn't appear that AMD condones the misreporting. However, in response, AMD said that it was investigating the issue, but it doesn’t believe the chips will suffer excessive wear during the warranty period. So, after we wrote an article about the software vendor’s claims and its new feature (designed to detect the problem), we set out to determine if the new test was accurate and if there was any imminent danger to the health of Ryzen CPUs from motherboard makers cooking the books.
After testing three different X570 motherboards, using a variety of settings, cooling solutions and even firmware, we found that, while HWinfo does shine a light on some issues, it can output inflated values that aren't representative of actual power misreporting. Of the three motherboards -- an ASRock X570 Taichi, MSI X570 Godlike and an Gigabyte X570 Aorus Master, only the Taichi showed a huge delta between reported and actual power that resulted in increased performance. Those settings resulted in higher clock rates, voltages, and heat output. And that issue, which happened with the reviewer BIOS, largely disappeared once we installed the latest firmware. The remaining relatively small power variances of 10 to 15 percent are easily explained by factors such as VRM variations, though.
...
AMD's statement seemingly confirms that it wasn't aware of the manipulations. It will be interesting to see if motherboard makers end the practice, or if AMD finds that because the adjustments don't impact longevity in a meaningful way, the practice can continue. We'll keep an eye on newer BIOS releases as they trickle out for any significant changes to power telemetry reporting.

Quote:AMD in an official briefing call with us confirmed that the company's "Zen 3" client processors are on-track for launch within 2020. This refutes rumors that "Zen 3" based Ryzen processors had been delayed to 2021 in favor of giving the upcoming Ryzen 3000XT reign over the rest of the year. The call was chaired by AMD's client-segment product managers who were speaking purely in context of their product segment, which is how we deduce that they were referring to "Vermeer" and not [just] "Milan." They were responding to speculation that "Zen 3" has been delayed to 2021, forcing AMD to refresh its existing IP.
In the call, AMD told us that the information about "Zen 3" launching in 2020 is not under embargo, and so here we are. An AMD spokesperson told us that "the rumor on Zen 3 delay is inaccurate." AMD recently also refuted rumors of "Zen 3" being based on 5 nm, by putting out microarchitecture roadmap slides on the occasion of a recent investor relations event, which reaffirmed "Zen 3" as a 7 nm-class microarchitecture.
