  • New Intel 10th-gen H-series chips launched, suitable for 2020 MacBook Pro refresh

    mdriftmeyermdriftmeyer
    From TechPowerUp



    it appears DDR5 will give us much more in the baseline Mac across the board. When Apple goes LPDDR5 no more 8GB systems. They'll just use 16GB, but seeing DDR5 going up to 64GB per DIMM is sweet. That's a four fold increase. The Mac Mini should be up to 128GB and so should the Macbook Pro future models. The iMac if it has 4 slots we get 256GB, etc.

    These are not suitable for Mac. They are slower, hotter and far more power hungry than AMD. Results already show they are 14nm retreads.


    The base frequency of this chip is 2.4 GHz, and it has a regular 45 W TDP (sustained power), which can be run in cTDP up mode for 65 W. Two other plus points on this chip is that it is unlocked, for when an OEM provides more thermal headroom, and it supports DDR4-2933, which is an upgrade over the previous generation. Intel's recommended PL2 (turbo power) for the Core i9 is 135 W, and Intel says the recommended 'Tau' is set to 56 seconds for the i9, and 28 seconds for all the other CPUs. OEMs don't often adhere to these values for notebooks, but they are provided as a guide. It does mean that in order to hit 5.3 GHz, the Core i9 is by default allowed to take 135 W across two cores, or 67.5 W per core. Even at 60W per core, you're looking at 50A of current per core... in a laptop.

  • Elon Musk uses iPhone email bug to illustrate the importance of software innovation

    I admire what Musk does.  He's a rockstar in my book... but whatever Musk.  Maybe it's "fresh blood" engineers that are breaking the software?  Maybe it's not iOS that was buggy, but maybe identified a problem with Musk's email system?  Lot's of assumptions being made here.

    Fresh blood is necessary in every industry.  Experience, especially of those that have been in the industry a while is even more preferred as far as I'm concerned. 

    He's an overrated ass hat.

  • ARM Mac Pro coming sooner rather than later, says Jean-Louis Gassee

    Anyone who works in or develops HPC software cringes at this.  Sure it's likely you can make an ARM chip with the performance of high-end Xeons, but the world of HPC software is a million years away from XCode app development where you can flip a switch to build for a new architecture. There are so many bespoke libraries (e.g. Intel MKL) and years of optimization that have gone into getting HPC code to run fast on AVX Xeons.

    Apple is a bit-player in HPC with the Mac Pro because of their 'war' with nVIDIA ( cutting off access to the compute power of their massively parallel GPUs)  - it would just sideline them even more if they went ARM.
    GC (Grand Central) is Apples answer, as parallelism is the answer to supercomputer power.
    Works fine with XCode.


    Grand Central works as well as the Backplane and interprocessing designs of the CPU architecture. In short, it's not a panacea. Slap two TR or EPYC CPUs in today's Mac Pro and you've got 128 Cores/ 256 threads that nothing ARM designs with it's energy footprint limitations will ever touch. Zen 3 arrives this Fall. Sorry, but no, Apple won't invest heavy resources for a small market product. They'll decide between continuing with Intel, or finally move forward on AMD Zen.

    RDNA 2.0 is about to come out and it lays to waste the GPGPUs custom designed by AMD already. The rational mind says Zen 3/RDNA 2.0/Afterburner 2.0 in the next Mac Pro.

    It won't just be Apple. Costco searches every employee, every day of the week.
