  • AMD's 4th gen Epyc Genoa will have stuff unless it doesn't. (WCCFTech)

    Specifically, up to 96 Zen 4 cores, 12-channel DDR5, 128 lanes of PCIe 5.0, and a 6096-pin socket.  In a two-socket system 48 PCIe lanes of each CPU will be used as interconnect, making 160 lanes available for I/O.

    Supposedly with a 320W TDP configurable up to 400W.  Current Threadrippers peak at 280W, and most Epycs are lower; 400W is rather a lot.

    But a 96-core 4th gen will easily match two 64-core 2nd gen Epycs.  It will also have twice the I/O bandwidth and more than twice the memory bandwidth.

    I had seen speculation of 96 cores and wondered how they'd fit the 12 chiplets required - even with 5nm it would be a tight fit.  The answer is, make the socket bigger.

    It's also rumoured to support AVX-512 which is currently the only server benchmark Intel can still win.

    It won't appear until the first half of next year, though.

  • Wonder if they'll support three channel DDR5 on socket AM5.  The desktop I/O die is currently one quarter of the Epyc I/O die, so if they keep that ratio, it would mean three memory channels.

    Doubt it - though it would make for amazing APUs

  • WASM everywhere everywhere. (GitHub)

    It's a Web Assembly interpreter compiled using that run-anywhere C library.


  • Don't plug your new Arm-based Macbook into that USB-C dock.  (ZDNet)

    Because it might die.

    Two points worth noting.  First, Apple blames the dock.  Second, they've released a software patch for it.

  • The invoice for the viewscreen was in your spam folder.  (ZDNet)

    Alexa supports over 90,000 Skills.  What do they all do?  Amazon doesn't know, or much care.

  • Microsoft has a patch for that horrible NTFS bug, where you can scramble your filesystem by opening a file with a particular name.  (Hot Hardware)

    You can't have it.

    The patch, that is, not the bug.  The bug you can have.

    To be fair, this is because they are allowing beta testers to beta test.  Pushing a buggy filesystem patch out to a billion users would not end well.

Disclaimer: But it would certainly end.

1 Yeah, I'm irritated that I'm still using Windows, but so far that is a little eased by the fact that they aren't yet shown to be hitting the maximum level of Big Tech screwed up. 

I'm a little unnerved by the switch in harassment to change from using a local account to using a Microsoft account from 'remind me again later' to 'remind me again in three days'. 

I always planned for that machine to duel boot Linux, but have been too busy to finish figuring out what I need, and some of the programs I need to use right now may be Windows only.

2 Also, interesting thought.

The justification for Microsoft's odious subscription based licensing is that they cannot pay for their software engineering with a more user friendly model. 

Recently had a discussion/thought about tech when societal issues cause a decline in the effective level of wealth. 

An early collapse is expected with the Biden affair, because of the wealth destruction.  But the rot that underlies the Biden affair dates back thirty years, at least.

So, some of the effects on tech of the wealth destruction may be hitting some places early.  Perhaps as Apple has gone, so will Microsoft, and eventually worse.

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