14700K also has additional E cores for what that is worth. I've so far seen very little benefit from APO sadly, only a small number of titles which it supports.

Intel 800-series platform for Arrow Lake-S LGA-1851 CPUs leaks in a new diagram - VideoCardz.com
Intel LGA-1851 platform diagram leaked Intel is hosting a series of events for distributors and board partners to showcase and discuss their upcoming LGA-1851 platform. These events are part of the preparations for the launch of Intel’s 800-series motherboards, such as the Z890, which were...

Z890 leaked
No DDR4 support (previously known)
16x PCI-E Gen 5 lanes from CPU to PCI-E slots (for GPU)
4X PCI-E Gen 5 lanes from CPU (for SSD)
4X PCI-E Gen 4 lanes from CPU (for SSD)
Native Wi-Fi 7
Native Thunderbolt 4
Solid upgrade for Z890 over Z690/Z790 - though would have been nice to see the chipset x8 DMI 4.0 link upgraded to DMI 5.0.

Extra 4 lanes from CPU to SSD is a solid upgrade and puts the Z890/LGA-1851 platform ahead of AM5 in terms of IO.
AM5 (Ryzen 7000 series) has a total of 24 PCie 5 lanes on the CPU, 16X for GPU, 4X for NVMe and 4X for the Chipset, those are not usable, so a total of 20 usable PCIe 5 lanes, 1 GPU at 16X, 1 NVMe at 4X.
Yes it appears that Z890 has the same 20 usable PCIe 5 lanes on the CPU but in addition another 4 PCIe 4 lanes for another direct to CPU NVMe, so long as its PCIe 4.

Still a bit pathetic on the PCI-e provisioning though. I'd like to see Intel push the boat out a bit with a X79 type platform for the desktop which wasn't stupidly expensive at entry level at least and increased feature support significantly. 32x PCI-e Gen 5 lanes, USB4 and OCuLink support, etc. quad channel memory.

How much die space do PCIe lanes cost and are a lot of them really necessary for mainstream platforms?
On my B550 i'm running 16X PCIe 4 for the GPU and 4X PCIe 4 for an NVMe from the CPU, from the Chipset i'm running another NVMe, PCIe 3 4X.
That suits me fine for fast storage, for mass storage i stuff a bunch on SATA SSD's in there...
What's not good is when you only have 16 of the fastest PCIe lanes, so if you use a PCIe 5 GPU and a PCIe 5 NVMe it will take the 4 lanes it needs for the NVMe from the GPU, see Raptor Lake.

Possibly another Alder Lake moment for Intel?

It’s real and it’s the 6p sku
Might explain why AMD is suddenly jacking up the tdp in panic mode.
Maybe dropping HT is allowing for higher boost clocks.
They have that platform, but motherboard manufacturing costs are simply more expensive today.
It does say they think it might be an OC but still, that's not too bad (depending on price and heat)
HT can be worth 15%~ performance, so a pretty significant deficit for clockspeed to make up.
HT can be anywhere from ~15 to ~95% depending on application - not sure what the average is I think Intel quotes about 30%. So for some stuff it is a massive amount to make up. One of the game development tools I use regularly for packing data files gains 70-90% performance from HT.
EDIT: Intel quotes 30% as both a max and an average in different places, reviews come up with slightly different results depending on what they are testing.

GG if true. This is Intel's first chipset attempt on desktop CPU's, I expected it to be inferior in every way to Zen5.
Pre meltdown/spectre or in unpatched environments maybe, but that’s cheating extra performance out of HT and Intel can’t market that any longer.
I think Intel need to drop HT draw back their power use and save windows from tripping over itself from dealing with three types of processing pipes and two different chip architectures. Ultimately with Intels power use and drive to smaller nodes something has to give because we’ve reached the point the silicon is degrading pretty rapidly.
That varies hugely from processor generation and application - mostly the 20-30% impact are from synthetic benchmarks which doesn't represent real world use - a lot of applications only see a 2-5% decrease in HT efficiency from mitigations. I might be wrong but IIRC it is Skylake based CPUs which see the bigger hit, most generations before and after tend to not see as big an impact (I assume more recent processors developed post these mitigations have some hardware tweaks to reduce the impact).

The P core is still essentially rehashed Skylake at its core. Pun intended.
HT is probably seen as hindrance and liability now.

You can keep repeating that as often as you like, but it doesn't make it true.
Golden Cove had significant improvements:
