  • Why Apple uses integrated memory in Apple Silicon -- and why it's both good and bad

    Misses the other major benefit of SOC integrated memory. In a traditional system if I want to move an image from memory to a graphics card that image data has to be copied from the CPU's RAM to the RAM on the GPU, byte by byte. Similarly, if I want the GPU to perform some action on that image and return it then the result needs to be copied once more from the GPU back to the CPU.

    In Apple's SOC design, you do little more than hand the address of the data in RAM to the GPU, which then can perform the operation in place. You get tremendous gains in throughput when you don't have to copy data back and forth.

  • First Apple Silicon Developer Transition Kit benchmarks show Rosetta performance impact

    I know people are waiting to see what kind of numbers this machine puts out, but in a recent interview with John Gruber Apple’s Craig Federighi wanted to stress that the Developer Transition Kit that was released this week should not be compared to any future consumer product.

    “Even that DTK hardware, which is running on an existing iPad chip that we don’t intend to put in a Mac in the future, it’s just there for the transition, the Mac runs awfully nice on that system.”

    “It’s not a basis on which to judge future Macs, of course, but it gives you a sense of what our silicon team can do when they’re not even trying,” Federighi continued. “And they’re going to be trying.”

  • Apple turns off data protection in the UK rather than comply with backdoor mandate

    I’m not a lawyer, of course, but what’s the difference between getting a court ordered warrant to enter someone’s home or workplace if they are under investigation for bad acts against the population or the government and doing the same thing to investigate same on someone’s phone?  
    How do you find a balance between keeping people safe and respecting the rights of the individual?
    The point remains that you can't have a "secure" backdoor that's only open to certain people. It's impossible to make. So sooner or later it will be compromised and abused and then everyone is screwed.

  • Oracle will move headquarters to Texas from California

    ...and best of all, their state government stays out of the way.
    I assume that's code for letting corporations and business do whatever the hell they want?

    My take on it is simply that office space, cost-of-living and housing has grown so high in the Bay area that moving elsewhere seems like a good deal. 

    Unfortunately for your rant, in all likelihood the net result of all of those people moving to Austin is that AUSTIN real estate prices are going to start skyrocketing, and that all of those transplanted people are going to want the same level of services they once had in CA.

    The same exact thing happened to Colorado and Denver and Boulder a couple of decades ago when the tech boom hit with people moving there from CA... with the same exact result. Housing and COL went up, and the state started going Blue...

    Oh, what’s the view like way up there on the moral high ground?
    One could equally well ask how the view is from your mom's basement....

    But seriously. All you did was attempt to display your own superiority stance concerning his own stance. What was the point?

  • White House says Trump doesn't want to harm Apple and iPhone prices won't rise

    In the case of Walmart, apparently there are a lot of "was $19.95", "now $34.95"-style signs up all over the store.

    Of course, in most of the videos I've seen, people are blaming Walmart for "price gouging".

    And not placing the blame where it truly belongs.

  • Mac Studio 2023 review: You probably want this, and not the Mac Pro

    Probably this is common knowledge, but why has Apple made so much Not user upgradable? Is it to sell more new machines ? Is it to eliminate technical problems when users upgrade? Conceptually, I want more control of the thing I pay thousands for. 
    One thing is that all of the RAM in onboard the SOC and shared between the CPU, GPU, and various other systems like the NE. THat's where a lot of the performance comes from in that memory is on the chip and it doesn't have to go to an external bus to get it. Further, moving something like a shader or bitmap from the CPU to the GPU is basically just passing a pointer, as opposed to copying a bunch of bytes back and forth.

    Adding external RAM kills off aspect of the performance.
