Intel Unveils New Coffee Lake 8th Gen Core Line-Up With First Core i9 Mobile CPU (hothardware.com) 73

MojoKid writes: Intel is announcing a big update to its processor families today, with new 8th Gen Coffee Lake-based Core chips for both mobile and desktop platforms. On the mobile side of the equation, the most interesting processors are no doubt Intel's new six-core Coffee Lake parts, starting with the Core i7-8750H. This processor comes with base/max single-core turbo boost clocks of 2.2GHz and 4.2GHz respectively, while the Core i7-8850H bumps those clocks to 2.6GHz and 4.3GHz respectively. Both processors have six cores (12 threads), a TDP of 45 watts and 9MB of shared Smart Cache.However, the new flagship processor is without question the Intel Core i9-8950HK, which is the first Core i9-branded mobile processor. It retains the 6/12 (core/thread) count of the lower-end parts, but features base and turbo clocks of 2.9GHz and 4.8GHz respectively. The chip also comes unlocked since it caters to gaming enthusiasts and bumps the amount of Smart Cache to 12MB. Intel is also announcing a number of lower powered Coffee Lake-U series chips for thin and light notebooks, some of which have on board Iris Plus integrated graphics with 128MB of on-chip eDRAM, along with some lower powered six-core and quad-core desktop chips that support the company's Optane memory in Intel's new 300 series chipset platform.

    I am curious if these chips will break compatibility with the previous Meltdown and Spectre data sharing apps. Have they made changes to this feature set?
  • by Anonymous Coward on Tuesday April 03, 2018 @12:19PM (#56373301)

    So do these new chips have Meltdown and Spectre hardware fixes?

      No. Only workarounds in microcode that reduce performance.

        They also contain Intel's patented Deflect-Towards-AMD technology.

        Neither. Branch prediction is so Central to the CPU architecture that it can't be disabled. MS is working on it's compiler to see if can do special assembly tricks to hide the cache.

        Linux has kernel hacks which attempt to hide the data from the cache which hackers can still overide with skill

        • My understanding was that Intel's version of branch-prediction applies an access-rights check too late (allowing Meltdown snooping). That doesn't sound like it couldn't be fixed, especially since AMD doesn't have that same problem.
          • It can be fixed with a new architecture but not with a new microcode (microcode can only change so much).
          • Meltdown allows you to use timing attacks to snoop data across a system call. This is because Intel used an optimisation where they treated system calls as branches, whereas on AMD chips they resulted in a pipeline stall. The Spectre vulnerabilities work at the same hardware privilege level, though not necessarily at the same software privilege level (for example, you can read past a bounds check in a NaCl or JavaScript sandbox and read memory outside of the sandbox, which gives you the memory disclosure

        • Anyway, Facebook leaks data on our behalf, so why bother.

    In the meantime they have posted that there will be *NO* microcode updates for the older generations as stated in https://newsroom.intel.com/wp-content/uploads/sites/11/2018/04/microcode-update-guidance.pdf (serach for "stopped").

    There are software workarounds, but well... still leaves a bad taste considering they originally wanted to develop new microcode for those generations.

  • So, at long last, does this 9th generation Intel Core processor make coffee, as suggested by its name ?

    Come on now, we developers have been waiting ages for this essential feature !

    It's all window dressing. This is about as exciting as the difference between a 2017 Hyundai Elantra and and 2018 Hyundai Elantra. We are approaching almost a decade since Intel offered anything significantly different or improved.

      That is because Moore's Law has been dead for sometime now, because physics. Digital computing is reaching a dead end now. Apple is smart to start creating their new chips because Intel has hit a ceiling with nowhere to go.

        Digital computing is reaching a dead end now.

        Not until Netcraft confirms it.

      • Graphics cards has done fine.
        Ryzen did too.

        The problem is lack of competition.
        See what Nvidia do now as far as new models go.

    • We are approaching almost a decade since Intel offered anything significantly different or improved.

      One of the hardest lessons for hardware tech entrepreneurs to learn is that IT and personal-computing buyers, the majority of business for Intel, is not really interested in anything "different." What they want is what they bought last year faster and cheaper and 101% software compatible.

    • To extend your analogy, I would certainly purchase a 2018 Hyundai Elantra over my current 2008 model. But I've heard there were some safety risks with the newer ones, so I'll go with the Tesla (AMD).

  • Thought it said Intel Unveils Coffee Latte....

  • Laptops for content creators and CAD designers have been stuck in 4-Core, 3.3 - 3.7 GHz land for many, many years. 6 cores, 4.8 GHz max and also Optane memory will definitely make a difference in this area. If your last Core i7 laptop was bought 2 - 3 years ago, a new Core i9 laptop should feel much faster in comparison. I would have loved 8-cores instead of 6, but maybe that's coming next.

      "Laptops for content creators and CAD designers have been stuck in 4-Core, 3.3 - 3.7 GHz land for many, many years."

      That's because CAD has historically been gimped by GPU performance, not CPU performance. Please try your pondering again when you have actually used CAD machines for over 20 years!

    • I expect the 64-128MB of eDDR as a L4 cache will have more of an impact. For FPGA place and route, we've found that the desktop versions with this are about 50% faster than anything else on the market (performance is dominated by the sequential bits of the algorithm and the working set doesn't fit in cache).

    Every time I see the word "unveil", I first wonder, how long was it veiled to begin with? Then I wonder, how many more iterations are still "veiled", awaiting the perfect time to "unveil", so as to maximize profits?

    I imagine a bunch of marble pedestals with thin white sheets over them, each with red LCD displays counting down...... every now and then an alarm goes off and the room full of monkeys next door starts typing till they come up with a name......

  • Doesn't California now consider anything with "Coffee" in the name to be a carcinogen?
  • if AMD didn't come up with its competitive lineup. Suddenly intel is all interested in making chips that are beyond regular evolution process of last 5-10 yrs.

      They seriously need to check their prices too. I just retired an I3 machine taking only the vid and p/s to the new one, and had a thought about keeping the old one going with a slightly upgraded cpu. Seeing I5's going for only slightly less than the Ryzen 1700X I just went with for my main, I changed my mind quickly. Utterly ridiculous.

        Intel commands a premium with it's brand name. Especially among gamers where an i5 is faster than a Ryzen

    16 pci-e lanes ought to be enough for everyone.

    I wonder how jittery a processor designed with a LAKE of coffee will be. Bet it makes the computer really good at taking a SHIT though, amiright?!?

    "There's a "z390" (?) is a cannonlake chipset or "PCH" - and it's coming out next year - but that chipset is only for cannonlake processors, except there are (apparently) none of those planned for desktop."

    No sign of this chipset, no sign of an 8 core processor.
    Note this: https://www.intel.com/content/... [intel.com]

    The new chipsets do include the rumoured 'free' "Intel® Wireless-AC MAC"
    As well as a newer USB revision, 3.1 vs 3.0

    So what you end up with is the 'premium' z370
