Another week, another HW News. While not as busy as last week, we’ve still got some interesting stories. For instance, Linus Torvalds, the creator of Linux, as well as the main Linux kernel developer, has moved to AMD CPUs for his personal machine -- after 15 some years of Intel-based machines. There’s also a new development in the ongoing SMR saga: Class action lawsuits are being brought against WD in both the US and Canada.
We also have news of changes to the numbering of AMD’s AGESA microcode updates, updated ARM IP, Intel finally overhauling its stock coolers, and a terrible Nintendo Switch clone that’s begging to be sued.
On the GN side of things, we’ve been busy analysing Intel’s newest 10th-gen (Comet Lake-S) K-SKU CPUs and their respective Z490 platform. Most recently, we looked at the extreme auto voltage settings on Z490, including Vcore, power limit, and MCE. We also looked at the i5-10400 and i7-10700K. Spoiler alert: they’re both hard to justify.

Don't Run Z490 Motherboards with Default Settings: Thermals, Power, Boosting, & MCE for 10th Gen CPUsThursday, 28 May 2020
It’s difficult to differentiate motherboards, at least from a marketing perspective. There are definitely better and worse boards, and you can check any of the roundups or reviews Buildzoid has produced for this channel for explanations as to why, but “better” doesn’t mean “higher FPS in games” here. Using higher-quality or more expensive components doesn’t always translate directly into running Fortnite at a higher framerate, which makes it harder to communicate to consumers why they should spend $200 on board X instead of $100 on board Y if both can run the same CPUs. This has led to motherboard manufacturers playing games with numbers for boost duration, voltages, BCLK, and other settings in order to differentiate their boards from the competition with tangible performance increases.
We’ve talked about Intel turbo and “Multi-Core Enhancement” many, many times in the past. This serves as a companion piece to the most recent of these, our “Intel i9-10900K ‘High’ Power Consumption Explained” video. To reiterate, Intel’s specification defines turbo limits--the multipliers for boosting on one core, two cores, etc, all the way up to an all-core turbo boost. Here are some examples from Coffee Lake’s launch (8700K) and before:
