Question Raptor Lake - Official Thread

[Hulk]

Since we already have the first Raptor Lake leak I'm thinking it should have it's own thread.
What do we know so far?
From Anandtech's Intel Process Roadmap articles from July:

Built on Intel 7 with upgraded FinFET
10-15% PPW (performance-per-watt)
Last non-tiled consumer CPU as Meteor Lake will be tiled

I'm guessing this will be a minor update to ADL with just a few microarchitecture changes to the cores. The larger change will be the new process refinement allowing 8+16 at the top of the stack.

Will it work with current z690 motherboards? If yes then that could be a major selling point for people to move to ADL rather than wait.

Dang it, Intel. At least use a better IHS on your flagship CPU!

Actually there s factory delided SKUs sold by Intel to OEMs only, so covered by a warranty...

Anyway here Computerbase review :

Intel Core i9-14900KS im Test

Der Core i9-14900KS ist der erste Intel-Prozessor mit bis zu 6,2 GHz Takt. Überall die schnellste CPU ist er im Test am Ende trotzdem nicht.

Starfield and Spiderman Miles Morales are the only two games at stock RAM settings where i9-14900KS triumphs but taking more than 200W to do it! Meanwhile, the 3D chips are only a little slower but at less than half the power cost.

Yet another bin of the Raptor 8+16 part. I'm following the thread at Overclock.net and thus far they are not impressed. VID's at 6.2GHz are 1.5+ for all but the rare hens tooth part. Maybe you don't get a total dog like you can with the 14900K but honestly if you are going to run sane clocks that won't end up degrading the CPU, like 5.5/4.4 then any 14900K will do. You'll pay a lot to maybe drop your Vcore by 20 or 30mv.

At 1/4 of the power actually for the 7800X3D.

Other than this it s surely months that they are selecting dies for this CPU, so the 14900K were unlikely to have as good silicon quality for most parts, we can see that it has slightly lower idle power than the regular non KS chip.

One wonders how many years, if ever, it will take to reach this 6.2 GHz frequency with a future architecture...

AMD isn't interested. TSMC also isn't interested. Intel only did it coz they NEEDED something to sell to people who were bored with their 13900KS chips. I remember when AMD debuted the world's first 5 GHz CPU that actually wasn't attractive to own for the average user. And now Intel has managed to do the same. And we still don't have the world's first 10 GHz Pentium 4 that Intel promised us!

With CPUs architecture widening in the future I don't see 6.2Ghz or > anytime soon on any x86 CPU

Asus hit 9117MHz on theirs, and it only took 600L of liquid nitrogen and 100L of liquid helium.

As much as extreme OC is cool to watch, I do wish they wouldn't waste helium resources on it anymore.

I think they've just gotta hit that 10GHz mark and fulfill the Intel prophecy.

I updated the BIOS on my H610I DDR5 board to support 14th generation CPUs (in case I wanted to upgrade or sell it) and Gigabyte included some unrelated changes which limits memory speeds to Intel advertised limits. Now I can't set above 4800 MT/s for the memory speed on my 12600K whereas it was working at 6000 MT/s before.

Has anyone else encountered this? Thought I'd ask before I rollback to an older firmware version.

It's Gigabyte so probably a bug. May get fixed in the next update.

Apparently you won’t have to wait that long

Based on what???

 

[igor_kavinski]

I hope the delidding thing takes off, OEMs make tons of money on that, Intel sees that people actually care about lowering their CPU temps and creates a better IHS for the K and KS CPUs for $200 more. Maybe they will call them KD and KDS for the delidded versions.

Curious as well?

1.5 Vcore. Can't see that CPU lasting very long.

At least it would be under warranty if bought from a boutique PC builder. But that IS expensive

Minimum price I could get on a custom build at Maingear was around $2200 or so.

Also, maybe future node enhancements can allow them to lower the V-core requirements so maybe Intel could release the 6.2 GHz Anniversary Edition at some point that runs cool on air?

How many more node enhancements do you think there will be for 10nm/Intel 7?

As many as Pat wants!

I would bet that Intel 7/10+++++++++++ is tapped out. The "enhancements" over the past few years have just been more aggressive binning.

I have a 14900K. It is supposed to be able to run at 5.7GHz all-core but it would take a custom loop and more volts than I'm comfortable with to do it.

I turn off HT and settle for "only" 24 physical cores and run it 5.5/4.3 at <1.3 Volts air cooling at 200W max. Real world usage I give up maybe 5% in exchange for a much more efficient part that is cooler running and will most likely hold up without degrading.

In conclusion, everything beyond 5.5/4.3 (or so) is (borderline extreme) overclocking in my opinion based on experience with the 13900K and 14900K, both of which I've owned.

Don't get me wrong though, I don't blame Intel for this. They're doing what they can to sell parts and stay competitive. Many enthusiasts are having a blast tweaking these parts. That being said the official specs on these chips are kind of silly. 5.9GHz all core at 1.5V and 300+ watts is nuts both in terms of cooling required and how fast that much volts will kill the CPU. It's crazy that Intel even programs a v/f curve into the chip that goes up to 1.5V.

Hi, pardon my noobish question, I haven't had an Intel system since Sandy Bridge. The question is this (as I prepare to build a new PC and struggle choosing between Zen 4 and Adler/Raptor Lake): I'm not interested in OC, but I am interested in downvolting / power limiting. With a "K" (unlocked) CPU, must I have a Z690/Z790 board in order to somewhat limit the CPU's appetite (not to extreme degree), or is it doable with B or H series?

 

[igor_kavinski]

struggle choosing between Zen 4 and Adler/Raptor Lake)

Curious what the struggle is. Zen 4 consumes less power, all the cores are identical so no performance loss shenanigans with E-cores, you can upgrade it to Zen 5 and even beyond and it offers you AVX-512. Alder/Raptor Lake is a dead end. No one will stop you from going with it but at least you should have a good reason to give up on the aforementioned benefits of Zen 4.

 

[Alexium]

I'm on a tight budget, DDR4 support is a plus (as it's cheap and I already have plenty of it, while DDR5 is expensive and I think investing into it right now is too early). Second-hand CPU availability is a factor as well, there's 12600kf for $150 (or 13600kf / 12900k for $250). I could find 7500F for a similar price, and that's it. 12600k is about 20% faster than 7600X in the tasks I care about, for anything else both are plenty fast for years to come. AVX-512 is practically inconsequential, but as a software developer I'd like to play with it. I know there's no upgrading the LGA1700 system in the future, but I could go up to 13900k and it's a big boost (except that when that time comes it would be super inefficient compared to the new CPUs, so probably not). I'm not concerned with upgrading, just want the best bang for my buck now.

A side note: I got my first PC in 2003, and in these 20+ years I have only once upgraded the CPU without swapping the platform (e. g. the mobo + memory): when I went from Core 2 Duo E6420 to Q6600. The quad was a beast! Later you always had to upgrade the mobo to install a CPU that was a big enough upgrade. Even with Zen 1 AM4 (e. g. X370).
