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.
That can tell that you are running a benchmark and then works differently than it should and is expected just to give reviewers a better score?Perhaps a Smart thread Scheduler with AI?
I've been out of the PC game for a while.. Is this a good temperature? I'm at around the 60 deg C mark for the 9 minutes on multi core testing, but my Cores #0 - #5 are only running at 4.5GHz, not at the upper limit of 4.9GHz.
Not enough power...I've been out of the PC game for a while.. Is this a good temperature? I'm at around the 60 deg C mark for the 9 minutes on multi core testing, but my Cores #0 - #5 are only running at 4.5GHz, not at the upper limit of 4.9GHz.
My two questions are:
- Why are my P cores not running at maximum frequency here
- Are my temperatures good for this test?

4.9Ghz is for one core maybe two at most, your score is the same that can be found in benchmarks so everything is fine.I've been out of the PC game for a while.. Is this a good temperature?

I don't know exactly the setting, but this will make it take a lot more electricity, and run hotter. Right now you have a fair good and somewhat efficient machine. I would not mess with it.You're going to need to help me here... I haven't played around in a bios for many years now!

So your theory is that it uses too much power, and your solution is less efficiency cores and more performance cores?
For equal die size with more P and less E cores, you would only get 10 P cores, and 0 E cores, which would just lose across the board.

IMO, the opposite would be better.
In about the same die size, you could do 6 P cores, and 16 E Cores, would boost MT performance higher, and lower power. For really high thread server loads, they would be better off with 0 P cores and large amount of E cores.
If you went to 16 P cores, it would require a MUCH larger die.

As for the die size, Alder Lake-S is actually surprisingly small given the package size, so I'm curious as to why they didn't tape out a larger die for the high-end desktop parts.
Eh, it's not a 1:4 ratio, more like a 1:3 ratio. 4 Gracemont clusters are definitely bigger than 4 Golden Cove cores.
But that's just me nitpicking.
As always, more die size costs more money, and in a era of massive chip shortage, bigger dies means fewer of them.
Yeah, the only thing I can think of is the ring bus being used still has a limit of 10 cores (or core clusters) that won't be improved until Raptor Lake. Otherwise, a 10P+8E would have effectively Core 2ed Zen3, sweeping virtually all of the benchmarks with reduced power consumption.10 P cores would be preferable in a lot of cases. Not everything MT scales with core/thread count well enough to utilize 24-32 threads.

If the yields on 10ESF are as good as 14nm then I don't see that being a huge issue. If the yields aren't as good then it really depends on how bad they are and how many wafers are being chewed up to bring Sapphire Rapids to market.
It's pretty difficult to have a silicon shortage when you are the end producer and supplier of CPU's. But I digress, scarcity like silicon is a manufactured process. It's like belief when faith alone has no value, bearing or reason.Intel constantly ran short of CPUs in the 14nm era when silicon shortages weren't as bad as they are now.
If you are looking at building a CPU for massively parallel workloads, (Which 16 P cores implies) then using a larger balance of E-cores makes more sense. They are both more Area efficient, and more Power efficient. This is exactly why they exist.
With more E core bias, you can build a chip that is smaller, uses less power, and delivers more multi-threaded performance than your suggested 16 P-core monster.
I would expect Big Server chips to be exclusively E-Cores.

I just checked newegg. Intel has an adequate supply of alder lake CPU's. If there was a real shortage of Intel made goods. It would be the 10nm chips. You cannot manufacture scarcity when a semiconductor company makes their own products.There is an actual Silicon Shortage(of the metal)
Silicon’s 300% surge throws another price shock at the world
The metal made from the second-most abundant element on Earth has become scarce.www.mining.com
"A metal made from the second-most abundant element on Earth has become scarce, threatening everything from car parts to computer chips and throwing up another hurdle for the world economy. The shortage in silicon metal, sparked by a production cut in China, has sent prices up 300% in less than two months"
You're doubling down and sticking with that claim?I just checked newegg. Intel has an adequate supply of alder lake CPU's. If there was a real shortage of Intel made goods. It would be the 10nm chips. You cannot manufacture scarcity when a semiconductor company makes their own products.
They can't make Silicon by themselves, most likely they have a good supply of the metal for a few monthsYou cannot manufacture scarcity when a semiconductor company makes their own products.
You mean it's not made from magical unicorn farts (which Intel apparently also owns)?They can't make Silicon by themselves, most likely they have a good supply of the metal for a few months
4.9Ghz is for one core maybe two at most, your score is the same that can be found in benchmarks so everything is fine.
60 degrees is super for full load.
Unlocking it, or outright overclocking will not improve performance by enough to make it worth dealing with the high power draw and cooling.
Epic. From silicon and rare earth mines to finished products inclusive of all intermediate steps.I just checked newegg. Intel has an adequate supply of alder lake CPU's.

This is the correct answer. Intel guaranteed turbo boost frequencies for the 12600K are 4.5GHz for the P's and 3.6GHz for the E's. Depending on the quality of your silicon (and cooling/power supply) you may be able to get more but the increase in power is probably not going to be worth the added performance. Try some higher frequencies and check the package power and get back to us if you have the time.
