  • Early M2 benchmarks show clear CPU, GPU performance gains over M1

    Where is the Mac Pro? What chip will it use? Graphics? Memory? Slots? This is the real mystery.

  • You can still get a M2 13-inch MacBook Pro soon, as long as you want a stock configuration...

    It doesn’t matter how great apple’s designs are if they can’t manufacture them. 

    Time to take diversification away from China into account at the design stage. “But can we build it in Mexico?” should be asked about every new design from now on.
    I agree. If we need cheaper places to offshore then why not green our own backyard? After NAFTA passed net immgration with Mexico dropped to zero where it remains today. Immgration Central America could be the same if we began to focus on North and Central America for all of our resources, instead of China. Won't need a WALL if these countries were doing better economical and it would buffer our defense, manufacturing and natural resource pool.

  • Everything we know about the redesigned MacBook Air with M2 processor

    All I want is a 14" M2 (base processor) with MagSafe, 2-Thunderbolt ports,  32-GB RAM and support for 2-monitors. A few extra cores, the media engine and real function keys will round things out well, provided it has a black bezel and keys. Love to have colors but not with white anything.

  • Apple Silicon Mac Pro could combine two M1 Ultra chips for speed

    My guess is that the Mac Pro will use the same M1 Ultra as the Mac Studio does.  The difference will be in the system around the SoC.  With a larger form factor, they have more cooling potential and could bump up the clock rates a little... but really, the M1 Ultra is a monster as it is (both in terms of size and performance).  I would just take what Turnes said at face value, this is already the last of the M1 series.  And I think we will see a Mac Pro that uses it.

    So what could differentiate the Mac Pro?  In a word:  expandability.

    1) PCIe slots.  The M1 Ultra seems to have plenty of I/O potential, and a fast PCIe bridge chip would easily enable a lot of expansion potential.

    2) Drive bays.  The Mac Pro would have the same built-in super fast SSD, but in a large case a whole lot of additional storage can be accommodated.

    3) RAM.  This is where it gets tricky.  The Apple Silicon approach is to use in-package memory, and there are real constraints on how much can be put into a single package.  Some Pros just need more than can be fit into a single package, or more than is worth building in the TSMC production run.  So conventional DIMMs are needed to supplement the super fast in-package memory.  The question is, how does OSX use it?  Apple seems to want to keep the programming model simple (i.e. CPU/GPU shared memory with a flat/uniform 64-bit virtual address space), so having some fast vs slow areas of memory doesn't seem like the direction they want to go in (although they could and just rely on the M1 Ultra's ENORMOUS caches).  They are already doing virtual memory paging to flash, however... so why not do virtual memory paging to the DIMMs instead?  Big DMA data transfers between in-package and on-DIMM memory across the very fast PCIe 5.0 lanes would ensure that the available bandwidth is used as efficiently as possible, and the latency is masked by the big (page-sized) transfers.  A 128GB working memory (the in-package RAM) is huge, so doing VMM to get to the expanded pool is not as bad as you might think.  Such a memory scheme may even just sit on PCIe cards so buyers only need to pay for the DIMM slots if they really need it.  Such "RAM disk" cards have been around for ages, but are usually hampered by lack of direct OS support... and issue Apple could fix easily in their kernel.

    One thing for sure,  they won't include any drive bays for 5.25" devices or conventional hard drives. There is no advantage to having those devices inside of the case from a power, cooling or speed perspective. I also suspect the use of some kind of proprietary RAM expansion.

  • New Mac mini & display in 2022, Mac Pro & iMac Pro coming in 2023 says Ming-Chi Kuo

    We now know the MacMini is not getting a PRO or MAX chip, which is what I've been saying all along. I'm guessing the bare bones Studio starts at no less than $2k but it's likely to be closer to $3k. The Mini will simply get the base M2 that's coming with a few extra graphics core and probably the enhanced media encoder/decoder.
