Article seems not correct to call this High Bandwidth Flash, which seems to specifically mean what SK Hynix & SanDisk are doing, which is a chiplet that is alongside a GPU. https://www.tomshardware.com/pc-components/dram/sandisks-new...

Scaling to PCIe 6 is more bandwidth yes. But HBF is supposed to be going far faster, is the perception.

I don't know if the CCDs can actually use that much bandwidth. It's really for the GPU.

There were sometimes quite notable differences between 32-core ThreadRipper at quad channel ddr5 6400mhz vs 4800mhz. https://www.phoronix.com/review/threadripper-9000-ddr5-6400-...

Indeed yes it seems like the dual channel 6000MHz wasn't the limiting factor in many* tests. But also the lower power 395 has a couple massive wins, and I suspect it was almost entirely the memory bandwidth. For example the LLM test on page 2: it was that memory bandwidth making that colossal difference.

There were also tests like OpenVINO where memory bandwidth was the factor, but the x3d's cache was evidently big enough, with it easily scoring first place, the Strix Halo second, then the regular 9950 last place!

In a lot of tests, it seems like the extra 100w the 9950's were getting probably helped a lot!

I had a lot of years thinking multi-seat was the coolest & wanting to see it everywhere. Still think it's rad and obvious, but it's not clear how it'd fit into my life, what it would be for. This is cool to see & a great use.

It's a pity lpddr hasn't gained the higher capacity DDR recently gained.

That there are 48 and 64gb DDR dimms now has been such a sweet boost. It'd be awesome if 6x64GB were possible for Medusa Halo (384GB) but seems right now like only half that will be possible (192GB).

Feels likely to be a pretty direct test of memory bandwidth. Strix Halo (the AI Max+ 395) has quad ddr5-8000, which is both twice the width and more mhz. This is a great opportunity to see what workloads will make use of the 3d-vcache too!

I'm personally pretty excited for a new round of Mobile on Desktop. Usually a pretty good % of desktop speed, but tuned for much lower power, and the price is usually a little better. I have the Minisforum 795s7 with the 7945hx, which is a delightful zen4 that's very affordable. https://www.tomshardware.com/pc-components/cpus/amd-unleashe...

Wyoming and South Dakota seem even worse, having passed laws requiring age verification for sites with anything potentially harmful to minors. https://www.eff.org/deeplinks/2025/08/book-bans-internet-ban...

What a shameful era. These fools delegintize the state, delegitimize the legal system. Engaged in absolute foolery.

The suggestion I saw was that residents of these states need to comb through every government site they can and sue the government for anything that could be harmful to youth that they find. Theres really no practical limit no possible implementation that the state has allowed other than to age verify pretty much everything; return-to-sender-ing the paper bag of flaming dog shit seems like a semi necessary step here.

One thing that I think this discussion is highlighting to me is that there's very little support in the web standard (as implemented by browsers) for surfacing resources to users that aren't displayable by the browser.

Consider, for example, RSS/Atom feeds. Certainly there are <link /> tags you can add, but since none of the major browsers do anything with those anymore, we're left dropping clickable links to the feeds where users can see them. If someone doesn't know about RSS/Atom, what's their reward for clicking on those links? A screenful of robot barf.

These resources in TFA are another example of that. The government or regulatory bodies in question want to provide structured data. They want people to be able to find the structured data. The only real way of doing that right now is a clickable link.

XSLT provides a stopgap solution, at least for XML-formatted data, because it allows you to provide that clickable, discoverable link, without risking dropping unsuspecting folks straight into the soup. In fact, it's even better than that, because the output of the XSLT can include an explainer that educates people on what they can do with the resource.

If browsers still respected the <link /> tag for RSS/Atom feeds, people probably wouldn't be pushing back on this as hard. But what's being overlooked in this conversation is that there is a real discoverability need here, and for a long time XSLT has been the best way to patch over it.

Really wish registerProtocolHandler were more popular. And I really wish registerContentType hadn't been dropped!

Web technology could be such a nexus of connectivity. We could have the web interacting with so much, offering tools for so much. Alas, support has largely gotten worse decade by decade. And few have taken up the chance.

Bluesky is largely using at:// urls. Eventually we probably could argue for support for our protocol. But web+at:// is permission less. Tools like https://pdsls.com can just become web based tools, with near no effort, if they want.

Amazing technique. Previous submissions, and another good one on load balancing via PoTRC

Luck. And capturing strong network effect.

The ascents of the era all feel like examples of anti-markets, of having gotten yourself into an intermediary position where you control both side's access.
