  • First M3 benchmarks show big speed improvements over M2

    5nM/3nM = 1.6 recurring, suggesting a move from the 5nM process to the 3nM process would yield a 67% improvement in speed/power ratio. We are not seeing that.

    Not accounting for other changes and just looking at the size reduction ratio alone, I think the math would suggest that 3nM is a 40% reduction of 5nM, so maybe a 40% increase in speed?
    You guys are referring to a concept called "Denard Scaling", but that hasn't actually held up since the late 1990s, and it took a nosedive in the 2000s after 28nm.  Today's denser processor nodes lead to only single digit percent increases in performance.  Some of this is because voltage scaling slowed down.  Some parts, like caches, haven't shrunk at the same rate.  The capacitance of wires and devices is going up.  I remember NVIDIA was freaking out after the 28 nm node, because following that, even the cost per transistor wasn't going down.

  • Arm wants more than $0.30 per iPhone from Apple, but won't get it

    Yes -and just as Fujitsu designed the SVE SIMD extensions for ARM, it was Apple that created the 64-bit ARM ISA (v8+), totally redesigning it in the process, as they were the first company on Earth to require 64-bit ARM CPUs.  We used to joke about how the new ISA was "ARM" in name only.  So in theory, they could license the ISA to ARM.  And of course, Apple hasn't used the ARM microarchitecture since the Newton - it's a total Apple design.  So what benefit does Apple get from the ARM name?  Just participation in a wide software ecosystem, where people have already created "ARM" versions of popular software, vs the smaller number of companies who would make things for "Apple Silicon".

  • Mac Pro in danger after fumbled Apple Silicon launch

    The biggest apparent technical issue seems to be the failure of the quad-die Apple Silicon chip.  Perhaps they could make up for this with a dual socket system?  In principle, GPU support is a driver issue, not a HW issue.  It'd also be great if they found a way to do a two tiered memory system, so you could add terabytes of DRAM to the embedded system.  It sounds difficult, but Apple already pulled something similar off with the old two tiered SSD/HDD systems.  You'd let the 192GB of on-die RAM page out to the 8 TB of DIMMs.

    I think the main reason to design and support the Mac Pro, even if it loses money overall, is the halo effect.  People who love to use the MacOS, but need to do a larger scale project, particularly with GPUs, suddenly find they are forced to leave the Mac eco system. Just knowing that it is possible to still use MacOS at the higher end provides a layer of comfort in Mac based businesses thinking of expanding in the future.  It also might help with other products on Apple's road map, if it gains them experience in pushing Apple Silicon and GPUs to higher performance levels.

  • 'Minecraft: Java Edition' gets Native Apple Silicon support

    FWIW, I found the best performance using Azul's Java 17 ARM64 JDK with ManyMC.  It's truly amazing - peak is about 100x faster in everything - imagine selecting a Minecraft world and being able to start playing in less than 4 seconds! :). Minecraft and Java really seems to have the single greatest speedup going native of all applications.  For me, #2 was Blender, which was about 12x faster.

  • 'Minecraft: Java Edition' gets Native Apple Silicon support

    Your mileage obviously may vary.  I have a 16" Macbook Pro with the 10 CPUs and 32 GPU cores.  Running straight x86 Java Minecraft through Rosetta is honestly barely playable - sometimes you can get 20 fps, but you get frequent slowdowns.  It's a lot like trying to play Minecraft on my 2015 MBP.  Then I used MultiMC with (and this is important) an ARM version of Java that is NOT the one that comes bundled with MacOS.  I was shocked to immediately get 500-700 frames per second, just like YouTubers got!  But I found this was a peak case - it can drop as low as 60FPS.  But mind you, this is at high resolution and a render/simulation distance of the full 32 chunks.  (It you use the java that's bundled with Macs, you only get about 45 fps.)

    I've been doing a lot of comparisons with M1 native versions vs Intel, and Minecraft hit the #1 spot, often running a solid 100x faster in the best case, and about 5x faster in the worse case.  I will be overjoyed if the new Minecraft Java for M1 will be this good.  All they ever had to do was switch out which JVM they bundled Minecraft with, but I'm not surprised they kept this really low key - they don't want people noticing how much faster Java with M1 is versus Bedrock on Wintel.

  • Apple Car is a matter of 'when, not if' claims analyst

    Guys, no one is implying Apple will make a physical car.  It's like AppleTV - initially, everyone hoped for an amazing Apple TV that was transparent and thin.  But it ended up just being a little box you hook up to a normal TV.  There's no reason to think this wouldn't be similar in concept to car play.  Apple would just be helping car companies that need to play catch up on things like self driving features, etc.  And they could go to town integrating the infotainment/entertainment systems with their own stuff.

  • Netflix says use Safari on Apple Vision Pro, because you aren't getting an app

    Well, I'd say Disney Plus is the main competitor to Netflix, and Apple embraced Disney Plus and made it the premier video streaming app on VP.  That wouldn't make Netflix feel warm and fuzzy.  Honestly, the browser version of Netflix is great - the only big flaw is that so far, Netflix seems to block 4K and 4K/HDR on browsers - that would be a huge bummer for VP.  But I agree - it's not a market yet.

  • Apple looking to the past, working on how to put a Mac in a keyboard

    Buy a 16" Macbook Pro with an 8TB hard drive.  Tear the screen off with your bare hands.  Done. :)

  • Stolen Device Protection to thwart iPhone thieves with passcodes with time delay

    BirderGuy said:
    I’m not sure why this is necessary if you have two factor authentication set up.  Even if they get into the phone they would need the code sent to a trusted device.  No?  


    My understanding is one such trusted device is the phone itself, which the thief would be holding?  Plus, on a typical phone, if he had the passcode, he could then see all your emails and texts.

  • If you're using a Magic Keyboard, you've opened up an attack vector

    maltz said:
    I've never really understood the popularity of wireless mice and keyboards, but especially keyboards.  Mice, ok, the cord can be annoying if it tends to get hung up on something, but rearranging the cord or desk layout has always fixed that for me.  But keyboards are stationary.  What's the point of it being wireless?  And having to mess with charging and/or changing batteries is a hassle.

    That's not to say there aren't ANY use cases - I have a wireless keyboard/trackpad combo for my HTPC for when the IR remote doesn't suffice, for example.  And our conference room at work has wireless so the computer driving the large display there can be used by anyone at the table.  But the typical "sitting at your desk using your computer" case I don't really get.
    I'm guessing most of the time this isn't by choice.  For example, there was a long era where Apple devices didn't have enough ports, and splitters can only do so much.  And then there's iPads - AFAIK, most third party keyboards must be wireless, although now that iPads have USB-c ports, maybe a wireless keyboard would work.

    Honestly, for me, the worst thing about wireless stuff is you have to always wonder if it's charged enough. :)
