    AMD has outdone themselves yet again! Their lineup looks fantastic and I'm glad to see they aren't resting on their laurels. Highlights:

    • Genoa lineup has 16-96 cores/32-192 threads (lineup chart)
    • Support for 6 TB per socket of 12-channel DDR5-4800
    • AVX-512 support
      • On top of that, their AVX-512 extensions enable some ML workloads to be run on CPU (!!!)
    • 14% IPC uplift
    • CXL support (CXL.mem only for now)
    • Massive datacenter cost savings: 1, 2 (edit: Imgur backup in case those links 404)
    • Also laid out the roadmap for the rest of 4th-gen Epyc:
      • Genoa - general purpose
      • Bergamo - targeted to cloud providers; Zen 4C, up to 128 cores
      • Genoa-X - targeted to HPC; 3D V-Cache
      • Siena - targeted to telco/edge (lower-end servers)

    All I have to say is...wow.

    The possibilities here are enormous. Especially CXL, which I really don't think is being given enough attention. Having a shared memory bank that can be accessed in a cache-coherent manner is insane for HPC and HA applications.

    And Intel still hasn't released Sapphire Rapids. I wonder if they're going to delay it again after this tour de force.

    To quote SemiAnalysis:

    The 4th generation Epyc Genoa launch marks the 3rd consecutive generation where AMD beats Intel in the majority performance metrics. Rome and Milan made the cloud players start buying a lot of AMD, and Genoa is when the volumes jump across most remaining markets and end users. SemiAnalysis believes the gap between Genoa and Sapphire Rapids is larger than the gap between Milan and Ice Lake.

    I've been following this trial (and the Texas one) closely and I'm elated at this verdict. Even though it'll likely be tied up in (and reduced on) appeals for some time, it's a very clear message to any Alex Jones-wannabes.

    That said, I'm sure Alex Jones hasn't learned anything (or rather, he can't, because much like Joshua Moon, he's unemployable at this point - this grift is all he's got). Infowars continues to run the ad featuring footage from the trial about the cyrpto "donations" page, I'm sure they'll take clips from the verdict to run during ad breaks as well.

    I wouldn't be surprised if they were considering/neogotiating deals from AMD or Intel either (but can't say anything currently due to contractual obligations), but due to margins in the GPU business being what they are, I wouldn't be surprised if they just abandoned GPUs entirely.

    But as Greg said, they don't need GPUs to survive. Quite the contrary: although they might have to downsize some, GPUs have been (effectively) a cost center for much of the life of the 20- and 30-series, not a profit center.

    I'd love to see EVGA compliment their AMD motherboards with AMD GPUs, but I'd totally understand if they truly are throwing in the towel on GPUs.

    I agree with both takes. In the short term, I expect other AIBs will hesitantly take on some of EVGA's allocation (hesitantly because the 4000 series is likely to lose money at first due to the economy, crypto crash (and death of PoW profitability), etc.), but barring an executive shakeup that reverts the relationship with AIBs to what it once was, I would be shocked if EVGA is the only company to dump Nvidia.

    This is huge. EVGA was Nvidia's leading AIB for awhile (not sure if they still were in recent years, but they were certainly near the top), so to see them exit the market is almost unthinkable.

    If you don't have time to watch the video, these are the important bits:

    1. EVGA will cease all video card manufacturing operations.
    2. Existing customers will remain supported by EVGA’s warranties.
    3. EVGA has withheld inventory to help replace and fulfill cards as needed.
    4. EVGA expects to run out of RTX 30-series video cards by end of 2022.
    5. EVGA is staying in business.
    6. EVGA is not selling its business.
    7. EVGA will NOT expand into new product categories.
    8. NVIDIA was notified in April of 2022. (Edit: This was a misstatement. EVGA meant to say June, not April.)
    9. EVGA has thus far not entertained the idea of Intel or AMD partnerships.
    10. EVGA finished engineering samples of RTX 40-series cards, but will not be selling them.
    11. EVGA claims that employees will be reallocated.
    12. EVGA's belief is that NVIDIA has screwed it over.

    GPUs did make up ~78% of EVGA's revenue, but the margins were already quite low before the crypto bust (they never marked up cards by hundreds of dollars and sold to miners like ASUS, Gigabyte, etc.). Now, only 3060s and below are profitable, even before Nvidia decided to undercut all their AIBs by selling hundreds below MSRP.

    The more I think about it, the more it makes sense. Nvidia is clearly intending to eliminate the AIBs from the equation like 3dfx tried to do in the 90s, and EVGA is cutting its losses before that happens. Fundamentally, AIBs cannot compete with Nvidia on price because Nvidia doesn't have to pay the markup on their own chips, and with how little board customization is allowed these days, AIBs can't compete on much besides the cooler and power delivery.

    This video from JayzTwoCents also does a good job explaining the situation: https://www.youtube.com/watch?v=12Hcbx33Rb4

    What the fuck. That is insane. It's one thing when companies without a strong engineering culture take the "we test in prod" approach, but Twitter has kernel devs on staff because they've run into so many weird bugs at their scale (source: read it on HN at some point), I never would have thought they'd be one of those companies.

    Edit: Arbybear's comment has the article about Twitter's kernel devs, which was linked on HN.

    Some other Tweets from the thread that I found interesting:

    https://twitter.com/benjaminopowers/status/1569690510486343680

    Grassley noting that Twitter is outsourcing moderation to other countries, and the moderators lack tools and translators in some cases.

    This (sadly) doesn't surprise me at all, Twitter is far from the only company who does this.

    https://twitter.com/benjaminopowers/status/1569691440308961280

    Mudge leads off by saying Twitter is a decade behind competitors when it comes to security standards. Says company is misleading everyone from lawmakers to board of directors.

    https://twitter.com/benjaminopowers/status/1569691968849969158

    "This kind of vulnerability is not in the abstract. It's not far fetched to say that employees inside the company could take over the accounts of all of the senators in this room."

    This tracks with what I've read about a bunch of web3 hacks:

    According to zachxbt, he has been selling access to a Twitter admin panel, which allows employee-level access to Twitter tools. This might explain how many of the accounts were compromised despite being protected by multi-factor authentication.

    I have better data security practices for my side projects. This is jaw-droppingly bad. The potential for bad actors is huge - you could dox a lot of people just by pulling the geolocation data they've logged, which is apparently wide open to every employee.

    https://twitter.com/benjaminopowers/status/1569698169478422529

    "It [Twitter] is unable (to delete data) because they do not know where it is so they are unable to comply," said Mudge.

    I think it's also safe to assume they cannot fulfill discovery obligations if they don't know where things are stored. I wonder if their legal team has ever raised this issue before.

    Edit: Apparently, the "employees accessing user info for malicious purposes" idea I floated has already happened, but not for doxxing - it was for helping the Saudi government identify political dissidents.

    Sources:

    “Several Twitter users, who either followed Mr. Al-Ahmed’s Twitter account and/or had direct contact with him through the use of Twitter’s private messaging feature, have disappeared, been arrested, or have been executed,” the complaint said.

    Bitwarden has been a wonderful password manager (I've been paying for premium for several years now), but this worries me a bit. Investors always want returns, and I worry about the ways they might seek to get them.

    That said, assuming they keep their morals, I am quite curious what they're planning in regards to this:

    You will also see Bitwarden expand those efforts into areas such as passwordless, with new login options between Bitwarden clients, and developer solutions, to assist in the expansion of developer cloud deployments so prevalent today

    I found out about this from this comment, and it seemed surreal. The more I read about it, the crazier it gets.

    Basically, due to a 2017 Florida supreme court decision, if you sue your insurance company over a denied claim (like if a roof repairer intentionally billed your insurance an absurd amount), your attorney can collect 2-2.5x their hourly rate in fees separate from your payout. At that point, the incentive is to milk insurers dry, and, well, they have... 6 have been liquidated, 3 entered liquidation this year, more are ceasing operations in Florda, and those left are dropping policyholders by the boatload and raising rates.

    What's more, the Sunshine State is a standout nationwide. More than 75%, three quarters of all property insurance litigation in the entire country originates in Florida.

    Given how often Florida gets severe storms, this is an orchard ripe for the picking.

    The decision in question was issued on October 19, 2017, WILLIAM JOYCE, et al vs. FEDERATED NATIONAL INSURANCE COMPANY.

    From 4chan:

    It's the real deal. The dump contains, among others:
    The current driver source.
    Future driver source including unreleased ada and hopper codenames, the unannounced blackwell codename, all 3 of them are chiplet based and heavily riscv internally for the supporting processors (PM, decoding, encoding, and so on).
    Production and debug firmwares for everything. This would make nouveau work on latest GPUs, but it won't happen due to licensing issues.
    CUDA + every library, compiler and tool, including the enterprise ones, sources.
    The toolchain is very flexible, supports multiple GCC and MSVC versions, with a bit of work that would possibly mean supporting newer GPUs on older Windows versions in some fashion.

    This dumps gives us insight into the upcoming 5 years of GPU releases as well.
    The only thing that is saving nvidia right now is that the actual GPU chip schematics haven't leaked... yet.

    It's unfortunate that none of this will make its way into Nouveau, but at least we got some interesting information out of it.

    Edit: Apparently there's a DX12 for Windows 7 DLL (from Microsoft) in there...with a PDB (and nothing was stripped!). What a find.
