  • Tested: Will the new i7 Mac mini run faster with new thermal paste?

    I just finished testing the i3, i5 and i7 versions of the Mac mini with a variety of tests including power & heat generation. These were all tested stock 8 GB ram, all with 256 GB storage - not opened, no change in thermal paste.

     I found that with the i7 during a first test, or beginning of a long CPU intensive task starts off fast and got a result of about 1200 in Cinebench, then with additional tests (or continued long run) it scales down power usage from peaks up to around 150 watts to in the 90 watt range when Cinebench scores dropped as low as 1173 - but after 30-60 seconds the fan ramps up, and the performance goes back up - along with electricity usage where it climbs back up to 110-120 watt range and performance to match. I actually had the highest Cinebench score after the CPU was hot, and the fun was running at high speed when it hit reliably in the 1200 range with a peak of 1228. It does pump out quite a bit of heat.
    The i3 in the testing I was doing did not seem to have much of a change at all between tests, and even after running for a while I could barely hear the fan with barely warm air coming out.
    The i5 had a little bit of a variance, more than the i3, but not nearly as much as the i7 - it did generate more heat than the i3, no where near as much as the i7 - fan also barely audible. Running the same tests with the old 2012 quad-i7 it's fans were for sure the loudest - even the base 2018 i3 is faster than the 2012 quad-i7 in all tests, with the GPU scores being over 4x faster in CineBench & GeekBench.

     The Cinebench GPU test was also faster on the i7 where it reliably gets 44fps while the i3 & i5 were only getting around 41 fps. It is strange with all of them having the same integrated video, I even went back and re-tested to verify when I noticed it. (running a more advanced 3D app like Unigine Heaven or Valley it was only around 4fps so useless for gaming without an eGPU - I did test the BlackMagic eGPU with Radeon Pro 580 it jumped the same Heaven & Valley tests to around 36 fps with Ultra or Extreme settings - over 60fps with medium settings. while using around 130 watts of total power for Mac mini plus eGPU. Heaven in particular did get a slightly higher frame rate with Ultra settings on the i7 with eGPU than the i3 or i5 models which were only getting 29 fps)
    A better eGPU with an Nvidia card like 1080Ti or newer should be very usable not only for games, but things like video rendering with Premiere.

  • Researcher demos new macOS Keychain exploit, holds data from Apple in protest

    benji888 said:
    This is bogus:

    1) the person trying to steal your passwords has to first have access to your Mac.
    2) he then ran some app to get your passwords...I’m guessing all this app does is enter your Mac’s password for the keychain items automatically and then extracts them and displays them all in a list, so, again, back to 1).
    3) you can also lock keychain so that it has to be opened with a password, so they’d need not only your Mac’s password, but keychain’s password...this is not the default for keychain.
    1&2) It can be chained with other exploits - zero-day, or known for older MacOS versions which this exploit affects. 3) try this, and see how long you can run with keychain staying locked, especially while browsing sites that require logins, apps during startup, etc...

  • Does Apple have any premium buyers left for the iPhone XS and iPhone XS Max?

    Some of us only update once every 3-4 years - in my case I've been on a 4 year path - iPhone 4 to iPhone 6 to having ordered the iPhone XS (hopefully .5 to 1.5 weeks to arrive now after pre-ordering it last Friday morning)

  • Editorial: No Bill Gates, Windows was not iPhone's 'natural' nemesis

    If you want to argue over what is or is not "natural," I think there's a case to be made that things like monopolists, dictators, oppression, and violence are more "natural" than free markets, democracy, cooperation, and peace. In nature, it's a brutish battle to the death for survival. It has only been through human civilization that these other ideas (free markets, democracy, etc) have come into being. I certainly prefer the artificial human construct of peace than the natural state of conflict.

    Says someone who has never studied nature, or even read many articles.
    Many/most animals and insects cooperate - some even between species - scarcity of resource leads to conflict for sure, but so many operate as packs, herds, pods and more.  (There was relatively recent documented cases of humpback whales defending many other species from Orcas, even calling in reinforcements and extended standoffs, while reading about the recent ones it's mentioned that such things have been noticed for decades)


    "Current management at Microsoft has mostly corrected course"  - what? they have abandoned phones and most mobile devices other than 2-in-1 devices like the Surface.  They have refocused on server & cloud more than anything.  I guess the cloud part could be the corrected course - the rest is just defending monopolies.

    what the heck is TDS? I don't see anything that references that acronym in the story or comments.

  • Microsoft blocks Windows 10 update over Boot Camp driver issue

    Note that Microsoft supports Macs for longer than Apple does. The only reason why Apple does not support their computers for longer is because they want to force users to upgrade to their latest hardware even if it is slower than the computer they currently own (compare the latest Mac Mini to a top of the line 2011 iMac).
    There are things like 32 vs 64 bit in various components, features of the GPU (Metal support being the biggest thing to cause older models to drop off supported list), wifi, bluetooth and more.

    Why not compare the top of the line 2019 iMac to the Top of the Line 2011 iMac? or 2018 Mac mini vs the 2011 Mac mini?  They are very different class computers

    The 2018 Mac mini will out perform the top i7 2011 iMac's in most specs except GPU probably - 
    using GeekBench as an example 2018 Mac mini with i7 gets around around 5700 single core, and 24000 multi-core
    the 2011 iMac top-end i7 gets around a 3400-3600 single, with the top scores showing 11000-12000
    Disk performance is many times faster in the 2018 Mac mini - high-end SSD in new vs traditional HDD - or a much older model SSD was still SATA speed limited , as is wifi & bluetooth performance better on the new hardware.
    in GPU performance it looks like the Radeon HD 6970M is about 34% faster on average than the Intel Integrated 630 video - I'm honestly surprised it's that close - but there are GPU elements that the Intel 630 is faster at, so it's not a complete win for the 2011 iMac, and throw a cheap RX 580 in an eGPU case can get much faster performance (something I will actually be doing some app tests today or tomorrow with)
