With the release of Alder Lake less than a week away and the "Lakes" thread having turned into a nightmare to navigate I thought it might be a good time to start a discussion thread solely for Alder Lake.
Do you have a source for that? It seems reasonable that they only are running the 8+8 die right now. But, they theoretically could have used the 6+8 die for the 12600K and 12600KF. So, is there evidence that they are not doing so?
Right in the middle:There is no 6+8 die. Only 8+8 or 6+0.
Right in the middle:
Yes, but what is to stop them from using it?That's for mobile not desktop.

I wouldn't have guessed that there's a smaller 6+0 die, which I interpret as being only 6 GC cores and zero Gracemont cores. What's the point of such a die if Intel is going all in with the hybrid approach? It could have been a 4+4 or 4+8 product to offer a smaller die for the lower end desktop SKUs, but they went with 6 big cores instead? Seems like a headscratcher.

Marketing. Didn't want lower end products to have more cores than higher end products yet didn't want to regress on the number of big cores on i5.
I think it's silicon space and performance.Marketing. Didn't want lower end products to have more cores than higher end products yet didn't want to regress on the number of big cores on i5.

Largest mobile cpu would be a simimilar die size to the desktop cpu assuming 64eu are a similar size to two Pcores.
So they want a smaller die for the mainstream part and the volumes allow them to create a unique part for the performance required, the ultra mobile really wouldn't fit in where the 12400/500/600 cpus are going to be marketed, be it by offered cores or performance (games) given, although it's odd that they'd chose a small igpu cpu for the skus that will go into alll business and budget desktop computers for the next couple of years.
I didn't belive it initially but it appears to be real with the msi presentation. I presume intel leaves it out of marketing materials because it doesn't show off hybrid computing which is the big new thing.Is the i5 really a different die, though? If we already ascertained that, I missed it

I expect it to have other cheaper choices taken in manufacturing too. Probably has no solder and is tim on a thicker die with thinner ihs, need to eek out those margins for cpus that will cost ~$100.
Perhaps the I3's will be even more interesting? I don't know that I've seen any leaks on that front, but it's possible we could get 4P+2E or even 2P+4E - if 4C/8T was the old spec even a 6C/10T would appear to be a solid upgrade. You know, on paper.
i3 is 4+0, Pentium/Celeron is 2+0.
laptops are all hybrids, bigger in the consumer market compared to desktops.:/
Thanks for the info, sorry I didn't know.
I guess they gotta save something for the refresh. It seems like the number of PC's using the new P & E model is going to be a lot lower than I was expecting it to be.

One of the leaked roadmaps did show 1P+4e for the lowest end, sub 10watts tier.
Laptops are where I hope alderlake shines, the 2+8 version anyway, noway 6 golden cove cores aren't going to need some juice.
Do you have a source for that? It seems reasonable that they only are running the 8+8 die right now and will be using the best 6-core chips for high-end mobile. But, they theoretically could have used the 6+8 die for the 12600K and 12600KF. So, is there evidence that they are not doing so?
Yes it's for lower clocked non OC models, the fastest 6+0 seems to be the i5-12600. However this model comes with reasonable turbo speeds of 4.8 Ghz ST and 4.4 Ghz MT. On wccftech there is a SKU overview.
What will the worst 8+8 dies become? 12600Ks?
There are probably limitations. Depending where the faults are located, only certain parts have redundancy.If it's busted that badly it could be just about anything in the stack, all the way down to a 2+0 Celeron.
Your source please, if you don't mind?i3 is 4+0, Pentium/Celeron is 2+0.
I doubt there are a significant amount of further failure types to require chopping an i9 even further down, 6/4/2+0 on desktop is possible but a die that broken is probably on borrowed time.
Your source please, if you don't mind?
That's the rumor. Since Intel hasn't officially announced the locked parts, it's conceivable that they could change their mind and all i5 could end up being 6+4 and the i3 being 6+0. But the i3 is definitely going to be coming from the 6+0 die exclusively.
That's quite a jump if i3 ends up being 6+0. Most games can't put more than 6 cores to good use so it would make a really decent budget gaming CPU. I also just found out that there is no i3 in the RocketLake line-up. WTH? Is their yield that good that they dont have defective chips for i3?That's the rumor.
