I hope you are right about the big IPC increase. Do you have a source for the four way hyperthreading? The rumors in this forum is the first I have heard of it being used.
No official source so far. You would have to get into an NDA with MLID for that revelation.

Certain AI/HPC Apps that combine AMX/AVX512 that benefit from High Bandwidth memory will see a boost in performance in the Magnitude of Order when compared to standard settings. Thats where Intel will claim victory over any new AMD offerings. But on general task workload apps, Sapphire Rapids is 2 years late.

Royal core aims for double single core performance of golden cove and will have four way hyperthreading.. so royal core cinebench prediction 4000 single core performance.. just guessing
During that Keller's talk at Berkeley, he sounded like Intel was truly aiming for a something different. Was it a simple PR or is Intel really going to experiment? Who knows. There are always wild R&D projects with a long way to the market.

Ocean Cove is gone. Royal core on the radar? Who knows

Intel's management is faced with many big issues from process problems they've battled for years, a resurgent AMD, and the COVID PC buying spike ending, and this is what they deem important to spend their time on?

I guess from the school of "we have nothing positive to market, so let's distract people with pointless name changes!"

Intel Sapphire Rapids 300mm Si Wafer.

Total Complete Dies: 148

With 50 killer defects per wafer they could be getting 98 fully functional dies. Out of that how many 60C/120T Xeon Platinum 8490 are they getting?

This was a very good yield calculator but it's been on "Maintenance" for a few months now.

It's the dumbest...

Until they do something even dumber.
Hey, if anything it got me thinking about the Pentium 2 ads. The department of redundancy department is apparently out of ideas at Intel.

RIP Intel Spaceman

Marketing's gotta do something. Plus I think the idea was that the Pentium and Celeron product names were confusing people, so they figured they could up sales somehow if they just stuck to a series of numbers and letters and did away with the Pentium/Celeron titles.

If find this calculator to be pretty decent: http://cloud.mooreelite.com/tools/die-yield-calculator/index.html
Without knowing Intel's defect density we cannot calculate the percentage of good dies. But instead we can do a comparison:
  • Let us assume a defect density of 0,1 defects/cm²
  • For the Alder Lake 8+8 die with a size of 215mm² (10.5 * 20.5) you will get 207 good dies out of 256 in total - around 81% yield
  • To get 148 complete dies from 300mm with a squared die it needs to be 19mmx19mm = 361mm² (there is margin for error because of scribe lines)
  • Everything else being equal you get 104 good dies and a yield of 70.5%

The dumbest naming scheme in the history of Intel. Everyone involved with that decision should be fired IMO.
no, not just Intel but in the history of any company.

Convo:

Person 1: I got the new Intel Processor!
Person 2: Which Intel processor?
Person 1: You know, the one thats called Processor.
Person 2: ahh, I see. (wtf is this person talking about...)

Didn't notice it at first but the Intel PR makes it sound like it's only changing for laptops. So that there would continue to be Pentiums and Celerons for desktops.

Me on explaining why Sapphire Rapids-SP has been delayed due to bugs and Dr. Ian Cutress was not aware of the 12th(13th currently) Steppings Intel has gone through..
