Intel Meteor Lake 16-Core, 14-Core CPUs Surface In New Benchmarks

Intel is readying its 14th Generation Meteor Lake processors for the second half of the year. A product of the chipmaker's Intel 4 (previously 7nm) manufacturing process, Meteor Lake will arrive for both laptop and desktop formats but presumably on the former first. Unearthed by hardware detective momomo_us, we get a first peek at two alleged Meteor Lake processors for mobile devices.

Intel continues to go down the hybrid path with Meteor Lake. Meteor Lake, which features a multi-tile design, will employ Redwood Cove performance cores (P-cores) to handle heavy workloads while saving the Cresmont efficient cores (E-cores) for simpler tasks. The design allows for maximizing performance without sacrificing power consumption. However, Meteor Lake may feature a third type of core, presently rumored as the LP E-cores (low-power efficient cores). The rumor appears to be legit since an Intel patent has shown two additional Cresmont cores inside the SoC tile, which appears to feature a larger process node.

Meteor Lake has four tiles: Graphics, SoC, CPU, and IOE. The LP E-cores reside inside the SoC tile, which performs functions equivalent to the I/O Die (IOD) in AMD Ryzen processors. According to previously leaked documents, Meteor Lake supports "Low-power island CPU offload," implying that the LP E-cores' job may involve taking care of processes when the processor is in idle or sleep mode. If accurate, it would substantially help reduce power consumption in laptops. Meteor Lake, like previous hybrid chips before it, will look good on paper due to the overall high core count. In Meteor Lake's case, we would also factor in the LP E-cores.

The first Meteor Lake sample emerged with 14 cores that likely adhere to a 4P + 8E design, whereas the second Meteor Lake sample has 16 cores that should stick to a 6P + 8E layout. The remaining two cores in both engineering sample (ES) processors are from the LP E-cores. The 14-core Meteor Lake chip reportedly has 14MB of L2 cache and 16MB of L3 cache. The processor has a 3.26 GHz clock speed. The processor may very well be the recently leaked Core Ultra 5 1003H. On the other hand, the 16-core variant appears to have 18 MB of L2 cache and 24MB of L3 cache. It runs with a 3.07 GHz base clock and a 4.2 GHz boost clock.

However, the SiSoftware benchmark report doesn't pick up Meteor Lake's L4 cache (ADM or Adamantine). Although Intel's patent doesn't specifically mention Meteor Lake, early Linux patches have suggested that ADM is present on the upcoming 7nm processors.

Intel's hosting a series of Vision 2023 regional events this month, starting one that took place at Orland between May 8 and May 10. There are still three more on the chipmaker's list: Taipei (May 24 to May 25, Shanghai (May 30 to May 31), and Amsterdam (June 13 to June 14). Therefore, we may learn more about Meteor Lake in the upcoming weeks.

    The core/thread count is actually been misreported by the SiSoftware benchmark.

    Yes, this is the actual core layout config. 16-core variant will be based on a 6 P-Core + 8 E-Core + 2 E-Core layout while the 14-core variant is based on a 4 P-Core + 8 E-Core + 2 E-Core layout. The additional 2 cores are part of the SOC tile.

    Also, these are confirmed to be mobile parts. Since there has been rumors that we won't get a desktop variant in MTL series. Chances are slim.

    A simple and easy way to confirm whether this is a Meteor Lake chip is the fact that it houses 128 EUs which is only possible on Meteor Lake chips, since Raptor Lake and Alder Lake Xe GPUs max out at 96 EUs & they also don't operate at clock speeds of over 2 GHz (2100 MHz in this case).

    A desktop part seems unlikely due to the 128 EU GPU config. Or whether Intel will really put a 128 EU iGPU within its mainstream consumer desktop processors, remains to be seen ?

    As I've said before, I think putting the two LP E-cores in the SoC tile was genius.

    The SoC configuration with LP cores are most certainly mobile parts. Intel could release a 128EU desktop part, but I doubt it will with MTL as it's their first foray into tiles in mainstream. I'm really looking forward to die shots of tiled processors with different IGP/SoC/IO tiles.

    Within the last week, I saw a couple of web pages saying there were strong rumors that Meteor Lake will be mobile only.

    Next 2 desktop series supposed to be Raptor Lake refresh followed by Arrow Lake.

    All no more than rumor.

    Supposed to be getting rid of the "i" branding designation also, in favor of "Core Ultra".

    Meteor Lake will be crazy if it does all the stuff that has been rumored to date, including adding an L4 cache (less than 1 GB?) and an AI accelerator.

    A socketed Intel APU with all the EUs would be really interesting. People to this day are buying relatively weak 5600G/5700G desktop APUs, and are hungry for AM5 ones.

    Will the TSMC tiles in Meteor Lake limit supply compared to previous chips it sends millions of to OEMs?

    Mobile MTL chips will make their way into some mini PCs. If the price is right, just buy some OEM system.

    Can we not call it LP-E cores?

    That's confusing and a unnecessarily long acronym.

    Why not just call it L-cores?

    L = Low-Power cores.

    I think the point is that their microarchitecture is the same as the other E-cores. The differences are: where they're situated, the process node on which they're made (because of which tile they're on), and the clock speed limits to which they're subject (which would be responsible for the Low Power). So, I fully understand the desire to convey that they're E-cores, but primarily (exclusively?) engaged when the system is in a Low Power mode.

    I don't think LP-E cores will help in heavily multithreaded tasks. But the power savings aspect will still be worth it for mobile. Even a 2w Bay Trail Atom can handle audio and video playback. I just hope the switching between the LP-E cores and the rest is fast enough that we don't notice the slowdown from using the SOC ones.

    If these LP-E cores are used for I/O only it could be a winning design.
    Let these cores take care of HDD/SSD read/writes, memory management,Ethernet management,Sound, Windows maintenance etc....
    That leaves the P and E cores for programs only.
    And when not needed can be turned off or put in deep sleep mode.
    Maybe?

    We get a first peek at Meteor Late processors, not peak.
