Off topic question. Since we're clearly having success with Rocket Lake, I'm curious about Alder Lake. Apparently, the next processors will have small cores + big cores. Would macOS even know how to reserve the small cores for light tasks?
I would want to think that by design, Alder Lake should technically work like any other x86 CPU. I would like to think the chip will be designed to be seen by the OS as like any other x86 chip, but functions different internally compared to say a Skylake chip. But as dehjomz says noone knows if this efficiency cores functionality will be supported in macOS.

Is sleep working for this build? Or does it wake up immediately after going to sleep?

Ah-k, so the Energy Saver prefpane has been changed by Apple for Big Sur and no longer includes a sleep slider?

... setting the Display Sleep slider to 1 minute, the system sleeps then wakes right up 1 second later.

The sleep slider has been gone since High Sierra or one of those operating systems… the system by default goes to sleep soon after the the timer for when the monitor goes off.

sounds like something is causing the system to immediately wake up, but it could anything…from the Bluetooth controller to some other pcie peripheral. not sure what.

I would like to think so too. But we don’t know if intel will implement hardware scheduling to park the lightly threaded apps onto the little atom cores automatically, or if the OS thread scheduler will need some updates to be aware of Alder Lake’s cpuid and more efficiently use the little cores.

Would be interesting to see what, if any, changes were made to the Linux kernel thread scheduler for Alder Lake. The problem we face with alder lake is that until Apple natively recognizes its cpuid, we have to spoof an older cpuid like comet lake which only has big cores. Who knows how this interacts with the code paths for big.little thread scheduling?

Apple has said it will support x86 for years, but that doesn’t mean it will add new code for Intel’s new cpus. Apple could do it, but will it is the question. I am fascinated by Apple’s performance with m1, but if Intel really has fixed its 7nm, then Meteor Lake and Lunar Lake could be beasts indeed. So I’m wondering if the future performance from Intel’s cpus will be so massive that it compels Apple and Intel to mend their relationship. Then Apple continues releasing future x86 products (and updating their kernel to support new Intel architectures). Very doubtful, but we will see what happens.

Actually no, this is Energy pref from latest Catalina on 2012 MBP:

Will follow up on Dortania fixes for sleep to see if there's a workaround.

Well I've been using more recent Macs... and the sleep slider went away around 2015 or so...

That is a big "if", I would say.

The fact that Intel was forced to release "Rocket Lake", the so-called 11th generation, on 14nm when it was originally designed for 10nm is proof it has not resolved the issues with its 10nm process, let alone anything more advanced.

I consider anything about Intel which is more advanced than its 14nm vaporware, including that "Alder Lake", as it has not demonstrated so far it has overcome the problems concerning them.

It seems as if Intel has fixed its 10nm node. Ice Lake 10nm Xeon has entered high volume manufacturing and is shipping now for client revenue, and they go up to 40 cores. Also, Tiger Lake 10nm 4 cores are shipping, and allegedly Tiger Lake-H (6 and 8 cores ) is coming. Only time will tell if they deliver Alder Lake this year, or if it is pushed back.

Intel's new CEO states that their internal compute tile for Meteor Lake will 'tape in' in Q2 2021. So we will see if they can deliver, or if there will be more years of delays.

That remains to be seen.

And if Intel can't deliver the so-called "Alder Lake" desktop CPUs on 10nm this year, that will be fun.

It's funny, a year ago I would be so excited and planning a new build. Now, I'm glad I just waited it out (and I didn't want to for sure.) At this point I feel like the ship sailed.

I did have a lot of fun with Skylake and Kaby Lake making hackintoshes. I stopped after as I just didn't see a need.
