Another interesting word from Intel Engineer about the future product beyond Arrow Lake S

SKXMCE02700108HIGHLIGHTA1.jpgIntel Skylake X 7980XE without Hyperthreading Performance with last Windows 11 24H2 Candidate Release on June 2024 

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.

WOW! They are retiring Hyperthreading! I guess with the split of P cores and E cores you will kind of compensate for and use E cores for light threads and "sort of" get close to same speed as HT would have given you. With the P and E core split you get a much cleaner uCodes that is less buggy - I get it. But instead, the issues of squeezing out maximum performance out of both P and E cores will land on the OS, optimizing the scheduler. Maybe Microsoft has worked on solving this problem... because the scheduler is not anywhere near optimum for mixed core workloads today.

Yes, They'd use Arm64 way for their product. However their process and packaging were way behind TSMC.

 

So. We'll facing it killer products way too late. 😍

very very interesting I think I should build my system now with 14900KS + Apex encore + 8400 MHZ G skill RAM And will upgrade to Panther lake or by the end of LGA1851 I would always prefer end of the current Tech over new tech , it might be issues and would require a lot of bios updates to maximize performance , fix me if I'm incorrect here but I do think it does make a sense

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.

Hey so I see you have detailed information there , so it’s not worth the upgrade by the means? The AI and stuff is not something that I have too on my rig? I mean features wise
