  • Intel's 13900K has a PassMark score.  (WCCFTech)

    PassMark - the benchmark used on CPUBenchmark.net - isn't a perfect benchmark, since there's no perfect benchmark except running your own application on the target hardware.  But I've found it to map very closely to the stuff I run, so it's the one I pay attention to.

    Score is 4833 single-threaded and 54,433 multi-threaded.  That's around the same multi-threaded score as the 24 core Threadripper 3960X, which uses 280W.

    On the other hand, the 3960X came out nearly three years ago, the 13900K uses up to 350W itself if you take off the limits, and the 13900K is also a 24 core CPU.

    On the third hand, the 13900K is 80% faster on single-threaded tasks on its Performance cores; it's the Efficiency cores that drag the overall score down.

    Still, if the difference between the cores doesn't matter to you, you're getting a workstation-class CPU from a couple of years ago in a standard desktop.

Tech News

  • Meanwhile the 7950X has been pushed to 6.5GHz on all cores.  (WCCFTech)

    On liquid nitrogen, yes, so this is probably not something you'll be doing yourself.  And it set some benchmark records, but again, not something you'll see direct benefits from.

    What is interesting though is that it only used 270W to do it - something that high-end Intel desktop chips can do without overclocking at all.

    I mean, that's still a lot, but it suggests that a good water cooler should be able to  support a respectable all-core overclock on this beastie.


  • Get3D generates 3D models from images.  (GitHub)

    It's another of the recent wave of AI-based image generation tools, though it takes a slightly different tack, analysing sets of images and trying to build a consistent 3D model from them.  The 2D tools - like Midjourney, which I've been playing with - don't actually have that kind of model of the shape of things, and will simply forget that a person's arms should be roughly the same length, for example, and end with hands.

    Since Midjourney (and similar tools) can take an image as reference, you could run the training data through Get3D, generate meshes, render them out into a scene, and then play that scene into the 2D generator to get a final product with consistent geometry, in that people don't suddenly have two heads.


  • The new wave of JavaScript web frameworks and why they should all burn.  (Front End Mastery)

    "Inspired by PHP" is a label very much akin to "LD 50 1ng/kg".


  • Nobody wants plant-based meat.  (The Guardian)

    A vegan friend mentioned that she tried these products a couple of times and couldn't stand the taste.  If you you're not vegan or vegetarian, traditionally plant-based meat - the kind where you have a cow eat the grass for you - is just as healthy and a lot cheaper.


  • NASA's test launch for the Artemis Moon rocket has been scrubbed for the third time in a row.  (CNN)

    Unexpectedly.


  • People can't even be bothered to steal Amazon's Rings of Power series.  (TorrentFreak)

    I might check it out at some point.  They actually did a pretty good job on Good Omens, and I have a Prime subscription for the free delivery (a big deal now that I'm 300 miles by road from the nearest warehouse).


  • Meanwhile I'm watching Kumo Desu Ga, Nani Ka? a.k.a So I'm a Spider, So What?

    It's the usual power-trip wish-fulfilment story of a teenage shut-in transported to a world that works like a computer game where they get untold power, except that first, the main character is a girl - common in early "isekai" stories, less so now - and second, in the fantasy world, she's a spider.

    It works because being a spider, even a magical spider in a magical world, is pretty awful, and because she survives through intelligence and determination, not through luck or being handed the world on a plate.

    I hesitated to watch this one because I'd already read a thousand pages of the manga and I knew the anime took a different approach to the story.  But not to worry, while the approach is different, the story itself is intact.

    Some things that take a long time to surface in the manga are apparent right away in the anime, but that turns out not to spoil things because even then you still don't know everything that's going on.  My guess based on those thousand pages turned out to be dead wrong.

  • Nvidia's new graphics cards are two to four times faster than the previous generation - if you are using ray tracing and upscaling.  (PC Magazine)

    If you're not using ray tracing and upscaling, they're not.

    Except somehow in the case of Microsoft Flight Simulator, where they are - and somehow the RTX 4080 is the same speed as the much more expensive RTX 4090.


  • Nvidia also explained why the new cards are so much more expensive than the previous generation: Because.  (PC Magazine)


  • And to gamers who are saying that the 4080 is really just a renamed 4070 to justify the high pricing, Nvidia had this response: Nuh-uh.  (PC Magazine)

    Nvidia is handing a golden opportunity to AMD and Intel here.  Intel simply isn't in a position to take advantage of it, but AMD might be.

    We'll see what they have up their sleeves on November 3.

Petaflopmobiles R Us Edition

Top Story

  • Nvidia had its big announcement.  (AnandTech)

    Lots of stuff, but the most immediately interesting are the RTX 4080 and 4090.  (Tom's Hardware)

    The 4090, launching October 12, has twice the performance of the 3090 Ti - from 40 TFLOPs to over 80 TFLOPs - while being 20% cheaper.  Which would be more impressive if the 3090 Ti hadn't been priced at $2000.

    The 4080 will arrive in November in two models, with 12GB of RAM and 40 TFLOPs at $900, and 16GB of RAM and 48 TFLOPs at $1200.  That's a significant difference; either the 16GB model should be called the 4080 Ti or the 12GB model should be the 4070 Ti.

    While the base 4080 has the same compute power as the 3090 Ti at less than half the price, it also has half the memory and half the memory bandwidth.  Nvidia is making up for that by increasing the on-chip cache from 6MB to 48MB (and 96MB on the 4090).

    AMD did that with the Radeon RX 6000 range, and it worked pretty well.  The options for doubling bandwidth over the 3090 Ti are pretty much restricted to HBM, which isn't exactly cheap.  On the other hand, moving from Samsung's 8nm process to TSMC's 4nm meant Nvidia had a huge number of transistors to play with - up from 28 billion on the 3090 Ti to 76 billion on the 4090 - so using five billion or so on cache was not a hard call to make.

    While $900 for the smaller RTX 4080 looks good compared to the $2000 3090 Ti, it doesn't look nearly so good when compared with the $700 RTX 3080, and gamers don't seem to be happy.  It's about 30% more expensive and offers about 30% more performance.

    Oh, an interesting point: They're PCIe 4.0.  Which means they'll work fine with my Bae case, though the standard 4090 might not fit.

Duck Tape Edition

Top Story

  • I managed to snag an Xbox Series X. The local electronics store - local to my old place in Sydney, that is - had it in stock a week after I handed in the keys, but only for in-store purchases. But the "notify me" button on the Microsoft store had changed to a "buy now" button when I checked today. The buy now button didn't work, but when I logged in and went back through the Xbox page I was able to add it to my cart and checked out.

    Since I am now moderately far from the madding crowd, I should have it in two weeks.


  • I also managed to snag the cord for my new electric mower, something I somehow avoided for 15 years with the previous one. So into town I went for some pliers and electrical tape. I have pliers and electrical tape... Somewhere.  Easier to go into town.


  • I've been hearing what sounded like ducks out the back of the house the past couple of weeks, but never caught sight of anything duck-like. Until today, walking back from the shops (which is quite a hike - there's a 400 foot elevation difference) I came across a herd of wild ducks crossing the street a couple of blocks from my house.

    So, yes. Ducks.


  • Australian mining company Fortescue Metals Group plans to spend $6 billion on "Net Zero" investments by 2030 - including hydrogen. (Financial Times)

    Hydrogen is useless as a mainstream fuel. The energy density is terrible and it leaks through everything. Anyone pushing it as a fuel is trying to sell you something.

  • The case for my new computer - the limited edition Hololive one - has shipped.

    I don't have any parts to go in it, but I'll sort that out in coming months.

    One thing: The case is laid out such that the graphics card is vertical, using a right-angle PCIe adaptor.  This is common in the kind of flashy show-off cases I don't usually buy, and by usually I mean ever.

    The PCIe adaptor is PCIe 4.  The CPU, motherboard, and graphics card I'll be buying will all support PCIe 5.  I think it will automatically fall back to PCIe 4.  If not I will be quite irked.

  • What does the future of AI hold for us?  Well first of all replacing the subliterate cretins who write for The Atlantic.  (The Atlantic)
    I recently started fooling around with Sudowrite, a tool that uses the GPT-3 deep-learning language model to compose predictive text, but at a much more advanced scale than what you might find on your phone or laptop. Quickly, I figured out that I could copy-paste a passage by any writer into the program’s input window and the program would continue writing, sensibly and lyrically. I tried Kafka. I tried Shakespeare. I tried some Romantic poets. The machine could write like any of them. In many cases, I could not distinguish between a computer-generated text and an authorial one.
    I've read GPT-3 text.  It's bullshit.  No matter the subject, it reads like pomo litcrit, because there is no mind behind it.  Indeed the entire point of GPT-3 is style over substance.
    I was delighted at first, and then I was deflated. I was once a professor of Shakespeare; I had dedicated quite a chunk of my life to studying literary history. My knowledge of style and my ability to mimic it had been hard-earned. Now a computer could do all that, instantly and much better.
    Most people are not brave enough to admit they are so bad at their jobs they can be replaced by a chat bot.
    If you asked GPT-3 to continue, say, a Wordsworth poem, the computer’s vocabulary would never be one moment before or after appropriate usage for the poem’s era. This is a skill that no scholar alive has mastered.
    If that's a skill no scholar has mastered, how can you tell that GPT-3 is doing it?

    To those who know nothing, everything is magic.

  • Sony has showed off a new range of PCIe 5 SSDs for PCs.  (Tom's Hardware)

    Sony previously released its own SSDs specifically for the expandable storage for the PS5 (which has strict performance rules), and it looks like the company plans to keep making them.  Speeds of these models are up to 9500MBps, and capacities up to 4TB.


  • AMD's Threadripper processors are twice as fast for developing large software project as Intel's best workstation chips.  (WCCFTech)

    Now, that's comparing a 64 core AMD chip to a 32 core Intel chip, so it's not unexpected.  But even the 32 core AMD chip is 50% faster than the 32 core Intel model.  The 64 core Threadripper has always been constrained by power and heat.


  • If you click Show Password in Chrome or Edge and you have Enhanced Spell Check turned on - or in the case of Edge, the Spelling & Grammar add-on installed - your browser might send your password straight to Google or Microsoft.  (Bleeping Computer)

    Oops.


  • Intel's NUC 12 Enthusiast is available for pre-order.  (Liliputing)

    This model has Intel's own Arc A770 dedicated graphics and a 330W power brick, so it's really, really not something anybody should be buying, particularly not at a starting price of $1699.


  • On the other hand, it looks like the regular NUC 12 is also shipping.  It comes with an Alder Lake 1240P or 1260P CPU, slots for up to 64GB of DDR4 SODIMMs and an M.2 slot, two USB 4 ports and two HDMI ports supporting a total of four 4k displays, and four regular USB ports.

    These new chips are quite a bit faster than the 11th gen equivalents, at least for multi-threaded tasks.

    I'd much rather have a Ryzen 6800U, but I don't think there's a mainstream NUC with that CPU yet.


  • Speaking of four 4k displays, HP's Pavilion Plus 14 can run two 4k screens via USB C and a third via HDMI.  That's nice to see given that some recent Dell models have been cut back and can only run one external monitor at 4k.

    The Framework laptop doesn't have a fixed port arrangement - it has four little modules that slot in with whatever mix of ports you want.  If you want four HDMI ports, you can do that.

    But the integrated graphics can only support four displays in total, including the laptop screen, so what happens if you have four monitors connected?  Answer: The fourth is disabled, until you close the lid of the laptop, when it is automatically enabled.

    That's pretty good.

A Plague On Both Your Datacenters Edition

Top Story

  • It seems like only yesterday that I mentioned Texas House Bill 20, legislation that attempted to designate large social networks as "common carriers" just like phone companies, severely limiting the companies' ability to engage in viewpoint discrimination. That legislation, and a similar bill in Florida, had been blocked at the district court level.

    Which injunction has just been overturned, nay, not so much overturned as nuked from orbit. (The Volokh Conspiracy)
    A Texas statute named House Bill 20 generally prohibits large social media platforms from censoring speech based on the viewpoint of its speaker.

    The platforms urge us to hold that the statute is facially unconstitutional and hence cannot be applied to anyone at any time and under any circumstances.
    In urging such sweeping relief, the platforms offer a rather odd inversion of the First Amendment. That Amendment, of course, protects every person’s right to "the freedom of speech.” But the platforms argue that buried somewhere in the person’s enumerated right to free speech lies a corporation’s unenumerated right to muzzle speech.

    The implications of the platforms’ argument are staggering. On the platforms’ view, email providers, mobile phone companies, and banks could cancel the accounts of anyone who sends an email, makes a phone call, or spends money in support of a disfavored political party, candidate, or business. What’s worse, the platforms argue that a business can acquire a dominant market position by holding itself out as open to everyone—as Twitter did in championing itself as "the free speech wing of the free speech party.” Blue Br. at 6 & n.4. Then, having cemented itself as the monopolist of "the modern public square,” Packingham v. North Carolina, 137 S. Ct. 1730, 1737 (2017), Twitter unapologetically argues that it could turn around and ban all pro-LGBT speech for no other reason than its employees want to pick on members of that community, Oral Arg. at 22:39–22:52.

    Today we reject the idea that corporations have a freewheeling First Amendment right to censor what people say. Because the district court held otherwise, we reverse its injunction and remand for further proceedings.
    Since the entire purpose of Twitter post-2018 - at least as its senior executives would have it - is to engage in viewpoint discrimination to protect leftists from reality, this is potentially devastating to the platform.

    It would also affect Facebook, of course, and comments on platforms such as YouTube and Instagram, but those platforms at least have other functions, whether you consider them worthwhile or not.

    Expect Twitter to become even more frantic in its efforts to be taken over by its most hated enemy, because if HB 20 or the similar Florida legislation survives the court challenges, Elon Musk is the only thing that stands between them and oblivion.

  • EVGA - the largest of Nvidia's video card partners - is so sick of dealing with the GPU company's bullshit that they've exited the marked entirely. (Tom's Hardware)

    Which is no small thing because video cards make up 80% of EVGA's revenue. Though not necessarily 80% of its profits - low margins, or right now, negative margins, being a major point of contention leading to the breakup.

    EVGA has said it has no plans to switch to making AMD cards instead. All warrantees for existing cards will continue to be honoured.




  • On the other hand GPU mining of Ethereum is now toast. (Tom's Hardware)

    This should help with the availability of next generation cards, though not sp much with Nvidia's financials, because they sold a lot of cards to miners over the last two years.


  • The 7900X is 30% faster than the 5900X. (Tom's Hardware)

    In both single and multi-threaded tests. This Geekbench which is not a great benchmark, but when comparing two almost identical CPUs it's a pretty good indication of what to expect.

    This also puts the 12 core 7900X well ahead of the 16 core 5950X. In fact, it would put the 7900X around the same level as the 28 core Xeon Gold 6348, which sells for close to $3000.

    This also puts it ahead of Intel's 12900K in both single and multi-threaded tests. (WCCFTech)

    Though of course Intel has the 13900K coming soon, which will offer significantly better multi-threaded performance because it has an extra 8 Efficiency cores.

    The WCCFTech article has a score for the 7950X as well, which puts it at 31% faster than the 7900X. Perfect scaling would be around 35% (extra cores and a small clock speed boost) so that is quite good.

    I'm looking forward to seeing more detailed benchmarks later this month, because I'm planning to build either a 7900X or 7950X system before Christmas.

  • The MOS 7600 is a microcontroller after all.  (Old VCR)

    This chip powered home versions of Pong and some other very early - very early - video games.  Since there was no published documentation and this was over 40 years ago, nobody knew whether the game was built into the chip at the hardware level (possible for something as simple as Pong) or a program written into the chips ROM, if it had any ROM.

    The solution?  Sand off the top of the chip very carefully - very carefully - and look at it under a microscope.  If you know what to look for you can see ROM and RAM and things like shift registers and logic arrays.
