Alder Lake-S leaks

[Grim5]

Tested in Aida64 the 12900K was pulling 250 Watts continuous power, 400 Watts peak.

This CPU is on Intel's new "Intel 7" process node, it seems they still haven't figured out how to make a power efficient X86 architecture.

Yep I believe I mentioned it previously that alder lake is at its building blocks just a continuation of the Intel Core architecture introduced in 2006. While AMD is rocking a brand new ground up Zen architecture, Intel is still peddling around with an inefficient deadweight architecture since 2006 https://en.m.wikipedia.org/wiki/Intel_Core


The "new from the ground up , efficient and powerful x86" replacement architecture is due for the 15th (thought it probably won't be called 15th gen and will get a totally new naming scheme)

 

[Grim5]

This is eye opening

Even though Zen is significantly more efficient than what Intel has right now it can't touch the M1. I think even Apple is surprised how well they did moving to ARM

no x86 can touch Apple's M1 in performance per watt. The M1 has triple the performance per watt compared to this Zen 3 5900hx


Cinebench R23 multi for the 65w 5900hx = 10.6k. Same benchmark for the 15w M1 = 7.7k

So the 5900x puts up 163 points in R23 per watt. While the M1 puts up 513 points in R23 per watt.

It just means the cooling is more efficient at removing the heat.

nope that is incorrect as well

Watch the gamers nexus video = hotter exhaust at the back of the machine doesn't mean the soc is necessarily cooler. You cannot make that conclusion it's extremely inaccurate (these thermal cameras are so inaccurate that the light in your room coming through your window will throw off the readings - even moving the console a few cm across your desk will give different readings - so the fact he had the 2 PS5's on a different spot on the desk automatically invalidates the readings among the other 100 variable he did not account for or calibrate for)

Thermal cameras like FLiR should never be used to make a conclusion about the temperature of anything unless they are used in an industrial setting where every possible variable is controlled and calibrated - any reading that does not comply to these standards is rubbish.

This is just influencer tech kiddies like evans buying cheap $200 cameras and thinking they can make scientific conclusion with a device that have no idea how to use and have never been certified trained to use one

Don't know if this was posted earlier but:





https://www.techpowerup.com/286638/first-tentative-alder-lake-ddr5-performance-figures-leak

785 points in CPU-Z. Apparently it's a 12600k. Latency is crazy high but this is likely due to not being in gear 1 mode.

Th Aida readings aren't impressive- double bandwidth compared to ddr4 but also double latency = so net effect for gaming will be no change. Anything that doesn't care about latency wil enjoy the double bandwidth

 

[Grim5]

The M1X is coming within a week or two and will settle this debate I would imagine.
No more trying to extrapolate results because Intel and AMD dont make many 15w products.

It gets 12 CPU cores and 16 GPU cores @ 35w TDP.




Here is a 5900HX in a $4k gaming laptop. https://www.notebookcheck.net/Asus-...etal-7-nm-AMD-Zen-3-Is-Stunning.540483.0.html

Puts up 13.5k in R23 while pulling 80w.

While the M1X gets 15k and while we don't yet know exactly what it pulls, I doubt its going to hit 80w and basically guarantee the macbook pro's using the m1x are going to smash 5900HX laptops in battery life.

ASUS Z690 lineup leaked, reveals that boards will not support both DDR4 and DDR5, DDR5 is exclusive to Ultra high end.

Alder Lake supports both DDR4 and DDR5, but DDR5 slots will be found on Ultra high end boards and everything else this generation will stick with DDR4, so be prepared to cough up lots of cash if you want DDR5.

DDR5 ASUS Z690 boards:

ROG MAXIMUS Z690 EXTREME
ROG MAXIMUS Z690 FORMULA
ROG MAXIMUS Z690 HERO
PROART ProART Z690-CREATOR 10G

DDR4 ASUS Z690 boards:

ROG STRIX Z690-A GAMING D4
ROG STRIX Z690-E GAMING D4
ROG STRIX Z690-F GAMING D4,
TUF GAMING – TUF GAMING Z690-PLUS D4
PRIME PRIME Z690-A PRIME Z690-A D4
PRIME Z690M-PLUS D4
PRIME Z690-P PRIME Z690-P D4
PRIME Z690-V PRIME Z690-V D4
PRIME Z690-V-SI-D4

A lot of these games AMD is testing are quite old now so I'd expect the 15% average to be best case scenario and doubt we will see those sort of gains when the reviewers test a wider spread and especially on newer titles.

A lot of them are competitive online games - these games get the biggest benefit at 1080p from removing cpu bottlenecks - like csgo which gained 40% performance from zen 2 to zen 3.


So while extra cache directly impacts things such as code compiling it's an indirect benefit for games - rather than directly impacting IPC, the extra cache will improve latency and communication speed and thus reducing the cpu bottleneck which exists at 1080p.

As mentioned Extra cache may become more important in time to come as it alleviates inter core latency for multithreaded games. But these gains are mainly benefit CPU bottlenecked scenarios so 4k gamers as myself would see little benefit for the time being

Take with a big tablespoon of salt and assume exotic cooling. If true even with a slightly lower margin, it appears Intel is taking the challenge seriously.
Hopefully a 1000W+ PSU won't be needed...

Even if it's exotic cooling, if the 12900k is beating the 5950x by 40% in games then Intel will be well and truely back on it's throne

12900k Cinebench R23 leak, tested on a z690 gigabyte Aorus Ultra board with quad channel DDR5 memory at 5200mhz CL38

scores 30,500 points @ 5.3ghz all core overclock, my 5950x gets the same with a 4.7ghz all core OC

I really hope these Golden Cove cores are as good as they're coming across, Intel will be onto a winner for a while if 8c/16t Golden Cove cores and 8c/8t less-than-Skylake cores can match 16c/32t of vanilla Zen 3. It's almost irrelevant that Zen 3D will trump this again, it's a damn good showing from Intel.

Disappointing that Intel still seem to have to overclock the tatts off their architecture and draw a bazillion watts to get there though. 8c/24t needs twice the power and 500MHz higher clocks to match 16c/32t in a synthetic workload.

It will still be another 2 or 3 years before Intel is ready with its brand new ground up architecture whos main goal is to return to efficient performance.

Here is the cpu hierarchy for Cinebench R23 single core score




And now we have the 12900k too

it gets 2050 points in single core

https://videocardz.com/newz/intel-c...g-4-spotted-2k-points-in-cinebench-r23-teased

 

[Grim5]

let's hope Alder Lake's single core synthetic actually translates into something usable, unlike Rocket Lake.

Going to come down to latency.

rocket lake had a solid 20% ipc improvement but zero gaming improvement due to the increased memory and inter core latency. If they've fixed the latency problems then there is last years 20% ipc and alder lakes 20% ipc to take advantage of - 40% gaming improvement? Hopefully

Alder Lake will be launched on the 27th of October and can be pre ordered from stores on the same day with the review embargo ending on 4 November, same day that sale starts.

https://videocardz.com/newz/msi-has-just-confirmed-intel-alder-lake-cpu-launch-date-november-4th

timeline:

27 October: Alder Lake launched at Intel innovation event

27 October: Alder Lake preorders open right after the Intel innovation event finishes.

4 November: Customers will start to receive their pre order CPU

4 November: Review embargo ends and reviews will be published

 

[Grim5]

I will laugh my arse off if it is all hype like it was with Rocket Lake and the only reason we are getting a 3D stacked Zen 3 is because AMD are reacting to the hype.

Whoops...

These companies don't read wccftech, they already know exactly what each other is working on and where it's at.

vcache Zen3 is amd saying it's uncomfortable with zen3's perf per dollar and wants to maintain high margins till zen 4

 

[Grim5]

Waiting for DDR5 always seems very strange.

Has there ever been any previous memory generation where being an early adopter had made sense from performance, or cost, or longevity point of view?

At least the DDR4 early adopters should all have been on HEDT quad channel so even if speeds were poor they had bandwidth.

This time with dual channel mainstream desktop leading, those who pay through the nose for what will quickly become the equivalent of what DRR4-2133 became to DDR4-3200 won't even have particularly high bandwidth.

Leaks so far have shown DDR5 running quad channel on the 12900k using z690 boards

and that's probably why there are no dual ddr4/5 mobos leaked so far - because it would require 6 ram slots right next to the cpu socket which is too much for consumer desktop boards outside of hedt or servers

 

[Grim5]

My comment did say advertise. Neither marketing or advertising are known for being bothered about truths.

EBay listings are proof of this

according to eBay sellers, a 5ghz 9900k = 40ghz cpu because 5*8 = 40

 

[Grim5]

Lenovo has announced you can buy its prebuilt Legion desktop PCs featuring an RTX3080ti and 12900k on a z690 board and DDR5 memory on 29 October

 

[Grim5]

That i9 box looks cool, its transparent and what looks like a gold wafer inside that the 12900k sits on

 

[Grim5]

Here come the samples.

Those are engineering samples probably stolen from AIB motherboard factories given they have a whole tray of 12900k chips

 

[Grim5]

Intel actually supply ES chips to users. I’ve seen a few in prebuilts over the years.

well that would be stupid and surely illegal

because yuki_ans bought one of the ES2 12900k chips and tested it, he also posted photos here

the ES2 12900k has a max clock speed of 4.5ghz, well short of the 5.3ghz max single core the retail chip has so if Intel put this ES2 into a prebuilt and advertised it as a 12900k that would be super misleading
