Intel is expanding its line of low-power, high-performance Core M processors. This fall the company launched the first Core M chips based on 5th-gen “Broadwell” architecture. Now Intel is adding 4 new models.

Like their predecessors, the new chips all have 4.5 watt TDPs, but some of the new models offer higher CPU and graphics speeds.

CPU-World has a good overview of what’s new, but here’s a quick run-down of the new processors:

  • Core M-5Y10c: This chip has the same CPU speed as the slightly older M-5Y10, but has a 300 MHz graphics clock speed instead of 100 MHz
  • Core M-5Y31: This chip is similar to the M-5Y10c, but has faster CPU speeds, with a 900 MHz base frequency and support for turbo speeds up to 2.4 GHz
  • Core M-5Y51: This one has a 1.1 GHz clock speed and Turbo speeds up to 2.6 GHz.
  • Core M-5Y71: The most powerful model has CPU speeds of 1.2 GHz / 2.9 Ghz and GPU speeds of 300 MHz / 900 MHz. Compare that with the Core M-5Y70 which launched in the third quarter, and which has 1.1 GHz / 2.6 GHz CPU and 100 MHz / 900 MHz GPU speeds.

All of the chips are dual-core processors with support for hyperthreading, and while they have have power consumption similar to what you’d expect from an Intel Atom processor, they offer significantly higher processing power.

Intel plans to expand its 5th-gen Core “Broadwell” lineup in 2015 to include higher-power, higher-performance chips for laptops and desktops. Many of the first systems to feature Core M chips including thin-and-light notebooks, tablets, and 2-in-1 systems where low power consumption allows for long battery life and thin, fanless designs.

  1. “Core M-5Y71: ….. CPU and 100 MHz / 850 MHz GPU speeds” I think it’s 900 MHz GPU speeds… Copy/Paste much?

  2. So 5Y51 better than 5Y70? When will devices with these new cpus be released?

  3. I’d be interested in a fanless 11-13″ ultrabook, even if it was the lowest-spec CPU. I don’t mind the noise of a fan, its just a longevity thing for me. Every laptop I’ve owned gets hotter (and consequently, slower) after about 6 months, and its always because it fills up with dust. Disassembling a laptop is not one of my favorite chores.

  4. All reviews i’ve read of fanless 11.6″ cheapish notebooks this and last year, that have pictures taken of the insides, looked like companies (lenovo, acer, etc) didn’t do jackshit to design or efficiently cool any of those notebooks. There were just empty places for fan, weirdly cut (leftover?) pieces of bare metal for cooling etc. and casing identical to the ones that have a fan.

  5. The older 5Y10 did not have hyper threading. But 5Y10c will support it.

    1. I’m not sure that your statement is correct. HT is not really a thing what you can simply fuse out. Maybe they just didn’t list it in the feature list, because everyone knows that a Core is HT.

  6. the 4.5w power number is good for thermal design, but what I would really like to see how well it can be software throttled (like apple’s cyclone, nvidia’s k1 Denver and qualcomm’s 805). With Atom being so gutless, core CPU really needs to move into the tablet space. I really look forward to the in-depth power reviews in the coming months.

  7. I’d only use a Core M chip on an 11.6″ or smaller screened device. Will I ever be able to see a quad core i7 on a 12.5″ – 13.3″ screened notebook? I was hoping that the ThinkPad X200 line would continue to be the most powerful 12.5″ business notebook but Lenovo decided to turn it into a gimped soldered down parts ultrabook with the X240 generation.

    1. It’s sad that Lenovo turned the X200 series ThinkPad into an ultrabook. The X200 ThinkPads were my go to notebook for portability yet still a full powered device. Replaceable parts was great too. I use the ExpressCard slot for non-USB based RS-232 and ADCs which is gone in the current generation.

      The new keyboard, trackpad/trackpoint and less durability are unfortunate as well.

    2. Check the Clevo w230ss, you can use an I7 quad core in 13.3 screen notebooks. (I just ordered one)

  8. Waiting to see what Asus will present in the coming month, I’m no longer interested in the power hungry i7 core proc… I’d rather a double battery life, silent work, portability and medium video settings in games then the powerful i7 machines…

  9. I’m hoping OEMs can make a fanless 11.6″ or smaller notebook with these Core Ms. So far Lenovo failed with their fan cooled 13.3″ and large bezeled Yoga 3 Pro which suffers from thermal throttling despite the fan going at full speed. Maybe there shouldn’t be so much emphasis on thinness.

  10. It’s getting to the point where I’m going to upgrade my HTPC just to save power! 😉
