I found this new and seems that is the Alder Lake-N processor.
And as expected it goes with Quad and Octa core configuration.

So.. small cores got a victory with more cores saying finally goodbye to the 2 core config?

It's unlikely that Intel could have launched Raptor Lake in 2021.
I meant, if Intel were firing on all cylinders and ADL never existed in the first place. We could have had RPL in its place and a year later, 8P+32E cores. That would have put AMD under some, if not immense, pressure.

May I request one more battle? Both Zen 3 and ADL at 8C/16T.
Sorry but for some reason, enabling only one CCD causes 5950X to perform well below a real 5800X/5700X. So it wouldn't be an accurate comparison. I can run the benchmark on 12900k with P-cores only, lets say @4.0ghz and see if someone here with a 5800X/5700X run the benchmark at the same speed...

8P+32E cores at 600W ? Sizzle. I mean - we would probably see some power delivery components on motherboards popping under pressure - not AMD.

Such a large die would be very expensive to make too. Even the Raptor lake 8+16 dies look pretty large.

They would have to downclock the cores a bit to keep them within 350W TDP. Wasting time on the useless Rocket Lake launch was the stupid decision that probably resulted in diverting valuable engineering resources away from more important things, like ADL/RPL and SPR.

They did it just to give their 14nm fabs something to do. Instead of backporting Tiger Lake, they could have backported Golden Cove cores without Gracemont cores to 14nm and gotten some competitive CPUs in the hands of customers around the time Zen 3 launched.

Yeah that's what I was addressing directly. I don't think they had the capability at all, even "firing on all cylinders".

That wouldn't have fared much better. Rocket's problem wasn't TGL, it was 14nm and an obvious lack of optimization for it.

Heat-wise, yes it wouldn't have helped but they could have gotten better than RKL IPC. Some dumb group of Intel engineers gets very excited at the prospect of high bandwidth RAM. That's why they wasted their time optimizing ADL for DDR5 and mispredicted DDR5's rate of adoption. They could have simply worked more on getting their IMC to play better with DDR4-3800 or DDR4-4000. Their fetish for DDR5 led to getting forced to release RKL to buy some more time.

I also blame idiot Intel marketing folks. Here's the sort of discussion they had:

Q: When is AMD going to release their DDR5 parts?

A: Not on time.

Marketing: Great! We can hype up the massive benefits of DDR5! We'll be first to market!

Engineers: Umm...there's the issue of higher latency...

Marketing: Who cares??? DDR5-4800 looks so much better than DDR4-3200. It's a no contest on paper!

And Marketing won.

I have enough rage right now to incinerate them, just by looking at them :mad:

Rocket Lake was an Ice Lake backport. No chance would they have been able to backport Alder Lake on a similar timeline.

They would likely have done better to release cascade lake die in up to 12-16 cores with decent L3 and only dual channel DDR4 with ice lake mobile covering the i3 and below market. Would have been cheaper to develop and compete just as well. Maybe even a cut down Cooper Lake die.

I would consider running it but you want the cpu capped at 4Ghz?

Waiting for Alder Lake -N and see how fares against the Celeron and Pentium in desktop tier. I mean, they are gonna dissapear in Single Thread, but how about Multi Thread?

And... the Intel Core i3-N305 appeared...

And looks interesting.
Multi Core wise is on par with the U tier Core i3. Single Core wise is weak.

Still, is an Octa Core design, so expecting the N-200 series beign another octa with low Ghz speed and the N-100 series being quads one.

Is pending to see the GPU performance. But this is bad news for Mendocino.

How is this bad news for Mendocino? Zen2 and Skylake traded blows in Performance and Mendocino is now built on 6nm better binned.

Alder Lake-N 8C/8T Gracemont Cores

Ryzen 3 5425U, Cezanne 15 Watt 4C/8T(Mendocino will have similar or better performance)

I agree!
No one will want only a quad core processor instead of an octa core processor for +/- the same performance. Maybe only AMD fanatics.
That's nonsense, if they give you the same performance there will be no difference(actually Mendocino will have better ST and about the same MT)

Actually Cezanne is a very good processor. But.. isn't it Zen 3?
Isn't Lucienne the one who needs to compete? And even Lucienne is a very decent uArch.

And there is one bench of it:

And has:
Single Core: 1078
Multi Core: 4145

If Mendocino needs to defeat it, it should be better than Lucienne. Single Core wise trade blows with Alder Lake -N, but multi core wise, is on dissadvantage.

Still, Lucienne has the advantage of having 6 CU in their iGPU, which is superior than the 2 CU of the Mendocino iGPU (and is the same used on the Ryzen iGPU from the 7000 series) and is pending to see Intel's offering

Better AMD should gave Lucienne a new refresh.

And I don't be surprised if Intel puts the Core i3 Alder Lake-N (Intel Core i3 N-305) a dGPU from them or nVIDIA.
