BUT they have found the perfect balance in development resources to arbitrarily implement a big LITTLE scheduling paradigm for products that may or may not be launched in the near future and successfully continued on the desktop? Please don't come with market share again, because AMD CPUs will have orders of magnitude higher market share than Ader Lake CPUs for the foreseeable future.
Edit: please don't take the tone personally, I just wanna convey somehow, how unfeasible it sounds to me, that this is not 100% conscious negligence towards any vendor that isn't Intel. No conspiracies, no evil overlords... but also pretty much zero fracks given.
I remember you were one of the most vocal AMDers on this forum always expressing pessimism about how the MS scheduler was going to play havoc with ADL.
You both forget what a scheduling mess that could end up to be. These different cores can look as building blocks on slides, yes. They certainly don't look like building blocks to desktop operating systems though.
Umm... you know that the little cores do *not* have HT, right? What I mean with that question: I just can't see 2 really strong cores together with 8 'maybe Skylake' cores at God knows what freq, even with perfect scaling and scheduling (don't forget, we're still talking about Microsoft here), touching 8 full fledged Zen 3 cores in an MT heavy workload.
This napkin math requires not just actual clock parity as you mentioned, but also 100% efficient and
perfectly managed windows scheduling between cores and threads and in-process tasks and such. Good lock with that! To Intel, I mean
You know what? I think Intel heard your warnings about how nasty the MS scheduler can get. They then took steps to beef up the scheduling mechanism of the new ADL. Keyword: Beef Up. Because this is where a lot of you, including the conspirators are displaying wanton ignorance. I already said in this thread that Intel and MS already have this same tandem scheduling already present inside Windows 10! Here's Intel on
Lakefield, first x86 hybrid chip lauched in Q2, 2020.
Intel Thread Director (ITD) is built on top of Lakefield Hardware Guided Scheduling (HGS) support. It provides Instruction Set Architecture (ISA) awareness to the operating system to indicate performance differences (and power efficiency changes) between the Performance cores and Efficient cores. This awareness allows ITD to schedule threads on the core which best fit the task.
So, all of you who'd rather push this nonsense about Windows 11 being purposely designed for ADL are doing nothing but displaying ignorance. Windows 11 is a platform that supports several generations of x86 arch designs from both AMD and Intel. Intel worked hard to avoid
any most pitfalls with the MS scheduler that y'all warned us about. Thank you. In essence, the notorious scheduler has not changed, only thing which has is Intel's foresight and hard work in ensuring that they don't leave their baby at the mercy of the MS scheduler.
Maybe AMD should've done same, instead of expecting the W10 scheduler to work seamlessly on W11.
No, wait! This is mostly mostly
@Joe NYC and other detractors looking to unload blame on MS without knowing the facts. In the upcoming high stakes game called ADL review, every point counts, and looking at how nobody gave ADL a chance to now seeing it trading blows with the current championship, it'll be fair to assume that some people have started losing sleep? Hah!
The 12th Gen Intel© Core™ processor is a new performance hybrid architecture that combines two core types.
