  • Semiconductor research group IMEC has published a roadmap taking the industry far beyond 1nm.  (Tom's Hardware)

    The most advanced process currently in production (at TSMC and Samsung) is a nominal 4nm.  Nothing about the process is truly 4nm, but it's as much 4nm as the old 14nm process was 14nm, so it's useful for comparison.

    The roadmap looks forward to the 3nm and 2nm nodes that are already under development at TSMC, Samsung, and Intel - and then beyond all the way to what they call A2 - a nominal 0.2nm - sometime around 2036.

    By which time I hope to be less concerned about annual increments in CPU performance, but faster computers let us solve problems that are too expensive to be practical at the moment, so this is a win even if you don't plan to put together a 26th generation Intel gaming rig with dual RTX 18080 Ti cards to play Minecraft 1.37.

    There's not a lot of detail about the sub-1nm nodes, but at 2nm they expect a billion transistors per square millimetre - about 6 times the current 5nm process.

  • Some next-gen AMD motherboards appear to have two chipsets.  (Tom's Hardware)

    There will be two chipsets available for Ryzen 7000 when it shows up later this year - the mainstream B650 and the high-end X670.  But it seems that they might be the same chip, only the X670 is two B650s.

    Which would make complete sense and fits in with AMD's design strategy for the past several years - design one really good chip and then glue a bunch of them together for bigger systems.

    A Ryzen desktop CPU consists of one or two CPU chiplets (up to 8 cores each) and an I/O chiplet.  The current motherboard chipset is the exact same chip as the I/O chiplet on the CPU itself, just rotated 180 degrees so the two can face each other.

    They're probably not going to do that with this generation because the new CPUs will have embedded graphics on the I/O chiplet, so it makes sense to have a generic motherboard chipset and use one on mainstream boards and two on high-end ones.

    Or the leaks might all be wrong.  One or the other.


  • But they're going to show off these motherboards tomorrow so we don't have to wait long to find out.


  • Apple is planning to expand manufacturing outside China.  (9to5Mac)

    The company is looking toward India (where labour relations have been somewhat fraught) and Vietnam.


  • Apple is also dumping a Chinese display manufacturer and sourcing from South Korea instead.  (WCCFTech)

    BOE reportedly decided to adjust the designs for their iPhone 13 screens to cut costs - without bothering to tell Apple.

1 Apple:  Good.  It's about time Chinese manufacturers started paying the price for lowering quality after acceptance BS.
I've mentioned before, I think, the custom keyboard I ordered as part of a group buy in March 2019.  This February, the people running the group buy contacted me and offered to let me switch to a different group buy that was being run, because the factory who was supposed to make the first one ghosted them.  There's not much you can do when a Chinese company does this to you--I just hope the keybs were to be paid for on delivery.
And the nice thing is that the replacement GB is for a newer version of the Ergodox so it's a slight upgrade.  I should hopefully get it late Q2/early Q3.

2 The guy who runs Avalanche Press had an amusing story about a Chinese publisher who held his products for ransom (Demanded more money in exchange for releasing the already-paid-for products from customs.)....Then turned around a year or so later asking if he had anymore printing jobs for them.  A fly on the wall of that conversation would have been amusing.

Speaking of games, anyone still has the link to that archive of paper and pencil game modules in digital files?

The Trove?  Seems to be deader than a very dead thing.  Even the backup torrents are deceased.

Apple pies are delicious. But never mind apple pies. What colour is a green orange?
