Question Alder Lake - Official Thread

[Hulk]

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.

 

[eek2121]

Clocks changed at the weekend so may just be an hour late if it was not updated. give it a few more minutes.

Clocks don't change until this coming weekend FYI.

 

[JoeRambo]

That should explain the reason why TPU had just the P-Cores enabled consuming much more power than made sense.

It can be easily explained without AVX512 -> turbo algos hobling up available power, rising voltage that is rising temps and rising temps increasing wattages. All for 50-100mhz gain @5Ghz range

But obviuosly AVX512 being available is amazing news for everyone

 

[Zucker2k]

Word of caution guys - do check what are the setups for systems, a lot of reviewers seem to be using higher end DDR5 like TPU
2x 16 GB G.SKILL Trident Z5 RGB DDR5-6000
36-36-36-76 1T

That will have nothing to do with Your run of the mill DDR5 @ 4800CL40 or even worse with DR or more channels filled.

HWUB also used DDR5 6000 CL36. I'm confused, you should be happy the platform isn't tied down to the crappy RAM we all feared could ruin the true potential of these chips. Hehe

I am happy, just on the other sites DDR4 3200C14 for fraction of price has same gaming performance as DDR5 and 3200C14 is not exactly a pinacle of DDR4 performance either?

 

[Zucker2k]

Like I expected, as per computerbase.de Golden Cove has 11% higher IPC than Zen3.

Math, please! How did you arrive at that figure?

 

[Asterox]

Officially, price=performance DDR5 memory is dead for a slightly longer period.

They changed in the UK. Ian is UK based so could easily be a time zone issue. That it is still is not published though probably means it is coming late.

 

[AtenRa]

AMD is perfectly fine, they can slash prices a bit on 5900x and 5950x. 11% higher IPC is really underwhelming given how much wider and bigger Golden Cove is. Intel needs to rethink its approach as this will not work in the long run, they need a brand new core just like AMD has done with Zen.

I believe they dont have too lower prices, they are going to release Ryzen 6000 in a few months from now.
Also the AlderLake platform cost is currently 2-3 times higher vs cheap AM4 B450, making AlderLake cpu's alone not that much cheaper vs AMD Ryzen 5xxx.

We will get it right after some earlier promised deep dives materialize. Reviewing under performing mobile processors made out of ARM cores with known characteristics is more important here since ~2013 or so.

Interestingly, Hardwaredeluxx testing suggest that AVX-512 can be activated by disabling the E-cores:

Funktioniert doch! AVX-512 mit Alder Lake-S - Seite 17 - Hardwareluxx

Core i9-12900K und Core i5-12600K: Hybrid-Desktop-CPUs Alder Lake im Test.

www.hardwareluxx.de

That's great. Though water cooling is a must with AVX-512 power consumption.

 

[igor_kavinski]

I like what I am seeing from Alder Lake in reviews. Time for AMD to roll back prices. I was planning for this outcome.

AMD made a mistake not having V-cache at Alder Lake launch.

 

[Kocicak]

The single fact that Intel needed to allow 12900K to guzzle so much power and let it run steaming hot while Ryzens chill at 65°C says a lot.

 

[TheELF]

This is the advantage that Intel has that can kill AMD, they can be much more aggressive with prices to undercut AMD and break their momentum.

The efficiency cores are super small and I assume also super cheap.
I doubt it's anything to do with undercutting, it's just cheap to make.
On the other hand I can't imagine cache being cheap or even that widely available for z3d having a real chance, at least until things go back to more normal.

 

[Heartbreaker]

I am happy, just on the other sites DDR4 3200C14 for fraction of price has same gaming performance as DDR5 and 3200C14 is not exactly a pinacle of DDR4 performance either?

DDR4 3200 lets you run in synchronous (Gear 1) mode, which lowers latency which matters for games.

I'd be most interested in a 12600K paired with DDR4 3200.

 

[igor_kavinski]

So Intel's E-cores "experiment" seems to be a success. Now all they need to do is double E-cores in the next generation for some nice multithreaded gains, and take out a P-core or two.

You are assuming they wanted to be late? They had to wait for the equipment to arrive before starting the mass production, and in this pandemic it is not easy to even get machines in time (my company is still waiting for a single machine to come from China and accepted one month and half ago, because train was the only reasonable cost-effective method of transportation). .

 

[coercitiv]

Gaming summary from Hardware Unboxed. They noticed DDR4 vs. DDR5 goes both ways in term of performance depending on the game, but also that some games run faster on Alder Lake with Win 10 while others prefer Win11.



When it comes to memory, for now DDR4 is the winner in my book, as the results above are obtained using the most expensive DDR5 memory.

That sucks if true but AMD could have sent samples to the press to rain on Intel's parade. They are either planning something big or just didn't expect Alder Lake to do so well.

So, thats 2% diff ? Can hardly wait for all the reviews. Seems like it does take 10-120 watts more or almost double the 5950x for productivity apps. And runs hot. I have not seem a review with details, just whats in this thread. No idea what cooler they are using. On either one. My 5950x's run on air. 615-2 coolermaster.

When it comes to memory, for now DDR4 is the winner in my book, as the results above are obtained using the most expensive DDR5 memory.

And DDR4 will continue to scale @ Gear1 at least to 3600C14 with tuned secondaries. Still from looks of what enthusiasts are already achieving with DDR5 - 6XXXCL30 or so for 50ns latency, it is obviuos that DDR5 and ADL will have bright future for those who have $$$.

 

[Markfw]

One thing I noticed.... You can only buy the 12600 and 12700 at newegg. Others OOS. Amazon has the 12900k for $1600!

They will be criticized anyway, if they sent samples to the press then people would have flamed them for advertising something not readily available. Unfortunately it works this way.

Haha scalping already of course!

 

[Timorous]

So Igor did some good gaming power consumption tests. In gaming ADL is really power efficient. See here

 

[leoneazzurro]

To be fair, in Germany they are all available at more than one shop, but in fact there are only the biggest ones to have availability, and the others do not even list them as "coming soon".
