After Intel 2024 vision even last week ago. I able to catch some word from engineer which everyone may interesting for.
" Why they've retire Intel Hyperthreading Technology since Arrow Lake S SKU to Nova Lake S SKU " .
It so clear that Intel was trails behind TSMC process and packaging about 5 years. Many architects since Willow Cove , Golden Cove , Raptor Cove , Redwood Cove and Lion Cove also getting many microarchitect issues. To be fair AMD also had these issues, too.
Both platform had security issues. For Intel side it was more trouple than other camp due it loss process and pakaging leadership to TSMC above. Thus the microarchitect rework or fixing or debug for engineering sample products alway shift and shift nowaday .
These cause major Intel killer product always release later than AMD and TSMC camp. For example " Sapphire Rapid ".
The FPU " Gather Instruction " or " Downfall Vulnerable " is the other best example that how long did it take for solving performance penalty? . But there are no time left for Intel especially their stocks holder. Gelsinger time was nearly over from many investors and US Goverment whom backup Intel more than billions dollars for their fabs.
The easy way to fixing these trails from Skylake Microarchitect to Raptor Cove were " Disable " Hyperthreading . And re-use combine old and new folks together. Arrow Lake S Combine 7 nm EUV Lion Cove P-Core and 10nm++ SuperFin Skymont E Core ( Cannonlake Modified ) to keeping E-Core R&D cost down. Maybe Darkmont E Core will following these scheme ( Sunny Cove Modified ).
The practice on column above Intel fan whom planning to buy LGA 1851 tickets must be re-thinking again.
Arrow Lake S -> Arrow Lake S Refresh -> Panther Lake S -> Panther Lake S Refresh coming soon.
Yes, your rig spec is overkill to run W11/W12 OS. They're good idea to used it 4-5 years before discussing to upgrade.
LGA 1851 may not socket elongavity platform as many people think due lack of PCIe 5.0 lane.
The Lion Cove microarchitecture above have 18 execution ports
on Arrow Lake ( Core Ultra 200 ) / Arrow Lake Refresh ( Core Ultra 300 )
( Skylake had 8 , Sunny Cove had 10 , Golden Cove & Raptor Cove also had 12 ports ) .
Times to maximize 18 ports execution performance always need few years later the CPU release.
The most interesting is Intel AVX10.1 feature on Lion Cove microarchitecture.
Maybe it is the first time to AVX2/AVX512 instructions running same speed as the Core without penalty hit. Let's see.
