Gigabyte Z690 Aero G + i5-12600K + AMD RX 6800 XT

There is a lot of good engineering in these new chips. But, if Intel could increase the P-core ratio, wouldn’t they favor doing so?

In Meteor Lake, the ratio tilts weirdly to only 6 P-cores and 16 E-cores. That’s a ratio of 1 to 2.7 in favor of E-cores. Admittedly, the IPC is expected to increase significantly so there may still be a net gain, but doesn’t it give the impression that P-cores are on their way out? As Intel improves and improves their smaller and more energy-efficient E-cores, eventually there will not be any reason for P-cores.

And that might make sense. It seems there’s no headroom left for scaling P-cores.

Intel's Next-Gen Desktop Platform Intros Socket LGA1851, "Meteor Lake-S" to Feature 6P+16E Core Counts

Keeping up with the cadence of two generations of desktop processors per socket, Intel will turn the page of the current LGA1700, with the introduction of the new Socket LGA1851. The processor package will likely have the same dimensions as LGA1700, and the two sockets may share cooler...

I think we’re going to have wait and see if these rumors for Meteor Lake are true. Some of the same sources misquoted RDNA3 performance. I don’t understand why Intel would have a regression in its P-core count. And speaking of rumors, those same source claim Intel will offer 8 P-cores on arrow lake.

I think so long as the IPC of the E-cores are increasing in new generations then that’s a win for consumers. But I don’t know how the upcoming E-core architectures (crestmont, skymont, and darkmont) will improve in ipc.

Also, Intel will sell more P-cores in its Xeon products. But we all know Intel’s Xeons have been extravagantly delayed. Sapphire rapid’s volume ramp has been anything but rapid.

That is actually correct. We can enable the NHI driver by spoofing the device ID of NHI0 to Titan Ridge, but we've found that this interferes with hot plug. Even without the spoof, hot plug is iffy, but it's a little less iffy without the spoof.

Thank you very much for your reply, because my motherboard is Gigabyte Z690 UD DDR4. After using your "SSDT-DTbtSsdt. aml", the Windows 11 system cannot be started, which is very strange. So currently, only "SSDT-MAPLE-RIDGE-RP09-V2B. aml" and "SSDT-DMAR. aml" are loaded. BIOS opens VT-D, and can only identify Thunderbolt 4 when it is cold started. It does not support hot plug.

That's how it shows up for me.

Excuse me, is the counterfeit ID 0x1137 0x15EB? Can you provide SSDT files? thank you.
Even if I do, it still shows No.

F20 BIOS released:

1. Checksum : F27C
2. Supports Intel 13th generation processor.
3. Improve CPU OC stability, DDR compatibility & PCIe Gen5 stability

Just an FY: F20 broke sleep for me. System will sleep, but if I let it sleep for more than a few minutes it, won’t wake and the fans are running slowly. I couldn‘t figure out any new BIOS settings that would make it work. Reverted back to version F6, and sleep is working again.

Will EFI provided in this thread work with KF (no iGPU) CPU's ?

Yes, no problem.

That's not because of SSDT. I set that up using device properties by getting the PCI paths using Hackindrom.

In January 2023, Intel will present a new Sapphire Rapids platform based on P-core from Alder Lake and Raptor Lake.

…followed in 2024 (if everything goes to plan, which is a big fat 'IF' with Intel these days) by "Sierra Forest" with E-cores only, to compete against AMD EPYC Bergamo using the slightly trimmed down Zen 4c cores (up to 128 cores per socket with Bergamo compared to 96 with Genoa). These Xeons may be hackintoshable—and anyway I'm very curious to see how Sierra Forest performs—but none of these parts are directed at regular desktop users, and for all practical purposes these come too late for us.

Hi, I am considering 13700K or 13600K, the question is which chipset to go, Z690 or Z790? Is Z790 BIOS is still problematic?
