Dealing with a nasty head cold. Can someone kind enough please give me the cliff notes of the last 1-2 weeks of Intel Alderlake info? Are we still A GO for a October launch?
In the last two weeks people discovered there's such a thing as PL4 for Intel CPUs. We are still in the process of acknowledging (as a group) the major difference between continuous power and peak power consumption for both modern PC power supplies and VRM stages.

As a general rule of thumb, as long as you see people arguing about power consumption in this thread it means there have been no further developments/leaks about launch timeline and/or performance. Get well soon.

What I find curious is the PL2 numbers. PL2 for ADL chips thus far have been lower (225W or 228W, can’t remember). Intel never learns…


One of them could be outdated. The reported PL2 for ADL-S QS was 228W.

Seems feasible enough, nothing there stands out as being hugely new nor surprising information either if I'm honest.

All except one thing.

What happened to LPDDR5X support that was supposedly coming with Raptor?

It confirms earlier rumors from Raichu and Moore's Law Is Dead, the 8+16 core count in particular. LPDDR5-6500 doesn't make sense because LPDDR5-6400 is the highest according to specification.

If Raichu is to be believed, Golden Cove is pretty massive:


6D 8U 512R It means that:
  • 6 Simple Decoder (not include Complex Decoder)
  • 8 uops/cycle
  • 512 entries ReOrder buffers.
  • Let we see.
    🥰
    I have more information but I can't release it.

Makes me worry a bit about Zen 4 if it's just Zen 3 with AVX-512 and minor improvements

If Raichu is to be believed,

This guy 'Raichu' is from chinese forum Tieba (Admin of intel segment)


Last year he said Rocketlake is 'suitable for gamer' (facepalm)

but he's right about RKL's perf lose a bit to Zen3.

Ooh, AT is claiming that AVX-512 won't be enabled even if you turn the small cores off on Alder Lake. Marketing must have decided that this was too confusing but too late to remove it physically from the client design. (or as I mentioned before maybe only embedded customers running Linux will get access)

So Intel still did increase everything in Golden Cove when they had to know that it will lead to similar increase to power usage and efficiency. It's Comet lake to Rocket lake again repeated in 10nm.

Regarding the architecture revelations: GC is huge. No wonder you can fit 4 Gracemonts in that same area. I wonder how much faster it'll actually be than Zen 3D.

Both desktop processors and mobile processors will now have AVX-512 disabled in all scenarios.
Oof.
