Intel "Lunar Lake-U" 17W Processor Offers Almost 50% Multithreaded Perf Boost Over "Meteor Lake" 15W Despite Lack of HTT

[btarunr]

There is some confidence behind removing HTT (Hyper-Threading technology) for the P-cores of its upcoming processor generations. Apparently "Lunar Lake" 17 W U-segment processors offer a substantial multithreaded performance gain of almost 50% over the current-generation "Meteor Lake," enabling Intel to do away with the power- or cache overheads that come with HTT. "Lunar Lake" will be Intel's third microarchitecture powering mobile processors under the Core Ultra brand; and its U-segment SKUs meant for ultraportables will come with processor base power values of 17 W. Intel will probably revise its platform specifications for the U-segment to denote 17 W, up from the current 15 W. Bionic Squash, a reliable source with Intel leaks, suggests so. The processors will come with a configurable base power of up to 30 W.

Intel "Lunar Lake" microarchitecture has a lot in common with the upcoming "Arrow Lake." For starters, both microarchitectures use the same combination of "Lion Cove" P-core architecture, and "Skymont" E-core architecture; however "Lunar Lake" comes with changes in the core-configuration, and the use of more advanced foundry nodes for some of its tiles. "Lunar Lake," much like "Meteor Lake," comes with a design priority for mobile platforms, which is why Intel is planning to launch this shortly after "Arrow Lake," with some reports even speaking of a late-2024 debut for the U-segment.



If the late-2024 debut rumor for "Lunar Lake" holds true, then it's conceivable that OEMs already have engineering samples and reference platforms for the chip, so they could evaluate and design their future notebook models with them. Apparently, some of these OEMs are already evaluating the performance on offer, which is where the leaks about the "almost 1.5x" performance gain over "Meteor Lake" seem to be coming from. Bionic Squash says that the number is based on multithreaded tests run on Cinebench R23 and Geekbench 5.4.5. "Lunar Lake" will see Intel push its notebook OEM partners to implement the "Lunar Lake-MX" MoP processor into their designs to achieve mainboard footprints and device dimensions rivaling the Apple MacBook Air. An MoP (memory on package) processor sees the Foveros tile processor and LPDDR5X memory modules share a single fiberglass substrate, to reduce PCB footprint.

50% mmm quite a substantial improvement

 

[SL2]

With 4 P-cores instead of 2 it better be.

Add 13 % higher power consumption.

Still impressive.

 

[DaemonForce]

This is very cool. I'd like to build a high availability NAS with this.

 

[Space Lynx]

MSI Claw 2 or perhaps even RoG Ally 2? hmmhmm

 

[Vayra86]

Perhaps Intel is really just better off making quadcores all the time?

Every time they get back to it, its something nice.

 

[roberto888]

Truly unprecedented gains! Having more actual P-cores will give you more performance than Hyper-Threaded ones. Ground breaking.

More BS claims from a BS CPU that won't be in a laptop for years on a BS lithography that has been talked about for so long that by the time this BS ships other chips will all be on TSMC 3N or 2N.

Fake 17W better than fake 15W*
*Under specific conditions and benchmarks

Is any laptop CPU actually enforcing the TDP limits anymore?
(Same goes for AMD)

Unless someone measures the power with an instrument, these perf/W claims mean nothing for laptops

Hmmm

Just arch improvements or another case of OS scheduler??

Doubling the P-core count could also make a difference.
