Intel "Nova Lake-S" 28-Core SKU With bLLC to Draw Nearly 300 W at PL2
Intel's upcoming "Nova Lake-S" desktop processors are nearing launch, and the rumor mill is intensifying as we receive more information about clock speeds, core configurations, and power consumption. According to a post on the Weibo forums, Intel's 28-core SKU with a big last-level cache (bLLC) integrated into the package will reach up to 296 W of power consumption at the Power Level 2 (PL2) setting. This is the maximum power draw the CPU can achieve during short bursts of turbo clocking, reaching its peak. Compared to the current top-end "Arrow Lake-S" 24-core Core Ultra 9 285K, which has a PL2 setting of 250 W, the additional four LPE-Cores on the latest "Nova Lake-S" will increase that number by about 18.4%.
Previously, we learned that "Nova Lake-S" will be very power-hungry, especially in the top-end SKUs. For example, Intel's top-end, overclocking-focused, dual compute die "Nova Lake-S" CPU with 52 cores will feature a PL2 mode with a power level of 474 W. This is an unprecedented number for an Intel consumer desktop platform, typically expected from a high-end desktop (HEDT) design. However, since this is a 52-core design that can be overclocked, it represents the highest CPU PL2 setting that Intel will be shipping with "Nova Lake-S." For single compute die SKUs, the PL2 limit appears to be 296 W.Finally, this could be the previously leaked Intel Core Ultra 9 4950K, identified as a 28-core "Nova Lake-S" desktop chip. It features 8 "Coyote Cove" P-Cores, 16 "Arctic Wolf" E-Cores, and 4 LPE-Cores. Intel is testing many SKUs for "Nova Lake-S," and a four-digit naming scheme could be necessary due to the numerous SKUs and configurations, so the new naming scheme might be on the way.

The TPU review thumbnail says it all.
For the power consumption of mainstream chips across workloads, it's enough if you read reviews and get informed, so that you don't post nonsense.

Right now a 16 core 9950X(3D) goes to a max of 210 W. That's 13.1 W per core.

The node jump argument is valid until frequency comes into play. If the 6.5 GHz rumors are accurate the very high frequency needs some juice and power ceiling to back it up.
So 300 W / 24 = 12.5 W per core.
As I said right at the edge, I wouldn't be surprised if it's higher, after all the 7950X and 9950X3D2 both go over 250 W.
If core count stays the same then yes power draw is expected to progressively decrease with each smaller node, but here we're talking about a 50% core increase which would create a two steps forward one step back type of situation.Then brace yourself. You're setting yourself up for disappointment with such sky-high expectations.
The "10800X3D" does not need more than the 170 W of today's 9900X (both 12 core CPUs) to beat the 270K in MT which goes up to 260 W.
You would have to trim quite a bit of 270K's power ceiling to match the "10800X3D" and that means losing some percentages compared to stock. Meanwhile you just add a multiplier to today's 9900X's relative performance score (to estimate the Zen6 SKU) and bang you're past the stock 270K.
Oh oh I know what you're going to say, why don't we increase the power draw of the "10800X3D" to match the 270K's? So maybe then the efficiency is ruined. Yeah but if it wins at 170 W it will also win (bigger) at 260 W, which means beating the 270K at the same wattage aka being more efficient.
How's that working out for ya?

As a reminder, Meteor Lake silicon in a compute tile was also too weak for desktop CPUs. That's why the whole generation on initial 1851 socket was cancelled and motherboards were hidden for a year by vendors. We saw ES of Meteor Lake S CPUs. In place of those, Raptor Lake refresh was introduced and 1851 delayed the whole year.You were rambling about MT efficiency. Money does not measure MT efficiency. Are you not aware of this? That's why I gave you TPU graph, to find out what the measure was. How about you learn this, once and for all, and stop wasting everyone's time for a change?
Anyways, as ive said, I find it highly unlikely for the 300$ zen 6 product to be more efficient at ISO power in MT compared to arrowlake, let alone novalake. Amd has good cpus but efficiency especially in MT workloads isn't their forte.
Blender:
9900X (173 W) , 70 s
270K Plus (~250 W) 56 s
9950X (~220 W) , 56 s (for more context)
270K Plus is 20% faster with 45% more power and 100% more cores. Bravo?
Have you got any data for 270K Plus running Blender on 170 W? It will likely score way lower. Is this what you wish to call 'significantly faster'?Again, money does not measure MT efficiency. Stop with this brain dead nonsense. When you introduce another variable, you need to name it accordingly.The MT efficiency graph was posted for you. You don't need much effort to look at it and understand it. Or perhaps you do.
I don't think I've seen a 720p display in over 12 years.
And why according to you - UMA denies upgrading your ram if with full dynamic UMA you can share your ram with the GPU too?
Low res reduces GPU bottleneck so you can correctly assess how strong the CPU is.
If one CPU is weak at low res it will also be weak at higher res.
Conversely 2160p increases GPU bottleneck so that reveals how strong a GPU is.
Moreover the DLSS Performance for 1440p output is 720p internal.
DLSS Performance for 2160p output is 1080p internal.
Those upscaled 720p to 1440p/1080p to 2160p are somewhat more taxing than native 720p/1080p but much easier than native 1440p or 2160p.
So I'd be fine with a high-end APU with something like 48-64 RDNA5 CUs + 128GB of LPDDR6, it'd be a much better portable solution than a conventional laptop with a CPU and GPU. I could stick with that for a good 4–5 years.
Enough time for better hardware to emerge or for the machine apocalypse to arrive.
There is no information indicating 20a and intel 4 cannot manufacture DT cpus. In fact, precisely because they possess the capability to manufacture DT cpus, intel had the relevant plans.sufficient for an estimate that is 70% accurate
It's not that complicated.
I use the single CCD to dual CCD scaling using the following CPUs.
Max power draw values
Frequency
Old data 2024
New data 2026
Performance
Conclusion
Also there is no such thing as "max power" for chips. They would use as much power as Intel wants them to use. If they want to release it at 200w they will, if they want to release it at 999w they will do that. The power limit isn't anything that's inherent to the CPU, it's a decision made by the marketing department, that's why I don't pay attention to it and I go with ISO comparisons.
17% more performance for 50% higher power is a great result. Take a 9800x 3d and try to get a 17% higher score in Cinebench. You think you can do that with less than 50% more power? :p
edit: I checked KeyShot which seems to be one of the worst case scenarios for Intel, and yeah, the gap widens quite a bit.
The thing is the apps that go way past the cap limit will be hurt the most, it doesn't seem very dramatic when looking at an average which contains ST workloads which remain unaffected.
Using the 14900K test I have estimated how the 270K would fare using a 175 W cap here. Using the CB scores as a reference. But it only works for the average not precisely determining the result per app.
You can see in the table the column marked "tested" for 14900K, those are the actual results from the review, then the "estimated" column uses the CB score as reference and then rule of three for the apps which go above the 200 W cap. Based on the power draw difference.
And the estimation is very accurate overall but not so much per app.
And I used the same approach for 270K.
So the thing with significant power capping is that the heavy MT apps get hurt most, and that's the intended usage of these SKUs, heavy MT. Thus capping the dual tile heavily might mean losing it's performance edge over the AMD counterpart, so now they're neck and neck let's say for the sake of argument both in perf and efficiency.
Then what's the point?
Just to win? For bragging rights?
That's stupid.
And there was talk of an extra EPS connector on the mobo, WTF, so making things more complicated and more expensive just for a pissing contest?
When they could make it more tame and keep it more affordable. Of course power draw also has implications for cooling.
So if they're interested in making a statement, as in "we won, chest pounding moment" and an "enthusiast" platform, where it's solely about the absolute performance and not the compromises to get there (including the buckets of money to have such a rig) then yeah they might aim more for perception and emotion rather than reality and reason.

Still I have some doubts about NL, power maxxing is a very cheap approach and the risk of overusing it is real.
It's good that AMD didn't repeat the 7950X with the 9950X and 9950X3D. They did with the 9950X3D2 but I don't care about that SKU.
They did juice the 9800X3D and 9850X3D because they needed the gaming king to remain king.
Now with the "10800X3D" there will be enough core firepower for MT that will satisfy many users.
So no need to juice as hard as with the previous 8 core SKUs.
If the 7800X3D was at 80 W, then 9800X3D and 9850x3D should have been at 120 W not 150 W.
But as I said there was a bit of pressure on them and initially it seemed like Zen5 underdelivered hence Zen 5%.
So they pushed it a bit more with the 9800X3D which came later because they also needed a very clear gap between it and the 7800X3D.
Again the statement dilemma, how clear does the statement have to be?
Meanwhile Intel made clear progress from Raptor Lake to Arrow Lake regarding power draw, but they were still rather high at max, and unfortunately it didn't help as AMD still won.
That's the point, there was no need for those MTPs, even with them overall the CPUs lost. Not by much but they lost. Also dead platform syndrome didn't help either with the adoption rates.
Just telling it like it is.
I'm expecting a bipolar approach with NL, very low idle power draw, very good ST performance and low power draw but then unhinged MT power draw to reach for the performance crown like there's no tomorrow (and thus rather poor efficiency at max).
I still want Intel to score a modest win overall, but man I'm losing faith. All the better, means I can't be very disappointed if they flop, however I can be very pleasantly surprised if they hit the bullseye.
But yeah Hybrid arch complicates things.Surpassing the 14900K is a piece of cake for the upcoming arch.

The first hurdle is the 20% gap between the 9800X3D and the 270K.
NL bLLC can take care of that, however going one on one with the "10800X3D" will be a very hard battle in gaming.
They're not going to repeat the Arrow Lake Plus prices with NL bLLC. Not even with the vanilla ones, although those might be significantly cheaper.
I'm expecting the single tile with bLLC at $550-600.
In our region (at least) the mofo retailers started to hike the LGA1851 mobos mostly after Plus Refresh launch. The CPUs being semi-charity meant being more attractive and thus the mobos were sought after too. Which contrasts with the lowered prices from 2025 when Arrow Lake was ignored and thus the mobos dropped significantly.
Still the AM5 counterparts are arguably more expensive.
It's not only RAM prices, it's also lack of progress. It all got derailed. If the RAMpocalypse hadn't happened, then CUDIMM kits would've gotten cheaper, the higher capacity kits would've slowly increased in frequency, more and more kits would've appeared with single sided 32GB modules and basically every other aspect that can be considered progress.
But it seems that for the NL and Zen6 launch the majority of available RAM kits will be bottom of the barrel in specs. Monstrously overpriced of course.
Unless the RAM kit makers (so not the DRAM makers, the big three) have stored some chips in order to muster some fancier kits for these CPU launches.
Hard to be enthusiastic all things considered.
